Referring to FIG. 5, a preferred embodiment of a leak-proof adjustment system for a lathe is illustrated. A turret 30 is rotatably disposed on a lathe (not shown). In the figure, the turret 30 has more than one platform 32. Each platform 32 has a set of fixing holes 34 and a pair of water outlet holes 36. These water outlet holes 36 communicate with an inner diameter tool holder 10 fastened to the platform 32. The guiding fluid passes through a tool set 40 mounted on the inner diameter tool holder 10 to cause heat dissipation.

The tool set 40 has an inner diameter turning tool 42, and the inner diameter turning tool 42 is detachably disposed in an elastic water outlet knife cover 50. The elastic water outlet knife cover 50 is mounted on the inner diameter tool holder 10 and detachably supports the inner diameter turning tool 42 to perform a cutting operation on a workpiece (not shown) such as a hole, a hole or a groove.

In FIG. 12, two outer-diameter tool holders 14 of different structures are respectively arranged on the corresponding platforms 32 of the turret 30. Each outer diameter tool holder 14 is detachably installed with an outer diameter turning tool 48, and the outer diameter cutting tool 48 performs a cutting operation of an outer contour on a workpiece (not shown in the drawing).

Next, the inner diameter tool post 10 will be described in detail with reference to FIGS. 1 to 8. A tool set hole 11 is formed in the middle of the inner diameter tool holder 10, and a slit 18 cuts off the wall of the inner diameter tool holder 10 surrounding the tool set hole 11 to form an inner diameter tool holder 10 having a generally C-shaped structure. . A base 12 and a clamping arm 16 are on both sides of the tool set hole 11. The base 12 moves relative to the clamping arm 16 in the slit 18 to limit the volume of the tool set hole 11 gradually.

The inner diameter tool holder 10 also has a water channel 13, a set of knife sleeve locking holes 20, two sets of fastening screw holes 24, a set of clamping screw countersunk holes 28, and an adjustment structure. Wherein, the water channel 13 is a crisscross pipeline arranged at the base portion 12, and has a plurality of nozzles, which respectively lead to the tool set hole 11 and two sink grooves 19 in the base portion 12, each of which has an inner diameter knife seat 10 的 底面 15。 15 of the bottom surface.

When the inner diameter tool holder 10 is fixed to the platform 32 of the turret 30, these water inlet grooves 19 face the corresponding water outlet holes 36, allowing some fluids such as water and coolant to flow along the water channel 13 into the tool set of the inner diameter tool holder 10. The hole 11 generates a heat dissipation effect on the elastic water outlet knife cover 50 (and even the entire knife group 40).

Of course, the leak-proof structure of this embodiment is indispensable. The leak-proof structure is a water-stop pad 73 that can be placed in the corresponding water inlet groove 19 of the inner-diameter knife holder 10. The water stop pad 73 is limited by the wall of the inner diameter knife seat 10 surrounding the water inlet groove 19, and surrounds the area where the pipe opening of the water channel 13 communicates with the water outlet hole 36. Under the squeeze of the inner diameter knife seat 10 and the platform 32, the water stop pad 73 not only prevents the fluid from entering the water channel 13, but also prevents spillage.

The countersunk head hole 28 of the clamping screw penetrates the clamping arm 16, reaches the base 12, and communicates with the slit 18. A set of clamping screws 27 are respectively used to lock the base 12 through the countersunk holes 28 of the clamping screws, and the clamping arm 16 is close to the base 12 and the slit 18 is reduced, so that the flexible water outlet knife cover 50 and even the entire cutter set 40 are enclosed. The tool holder 10 is clamped.

The locking hole 20 of the tool sleeve is directly connected to the tool set hole 11 through the connection between the base 12 and the clamping arm 16. One of a set of knife sleeve locking screws 38 is locked into the corresponding knife sleeve locking hole 20, and presses the elastic water outlet knife sleeve 50 into the tool group placement hole 11 to assist the inner diameter tool holder 10 to clamp the elastic water outlet knife sleeve 50, and can prevent the tool set 40 from rotating relative to the inner diameter tool holder 10.

These fastening screw holes 24 pass through the base portion 12 and the clamping arm 16 on both sides of the tool set hole 11, allowing one of a group of fastening screws 23 to pass through the fastening screw holes 24 and lock into the fixing holes 34, so that the inner diameter knife seat 10 is fixed on the platform 32 of the turret 30.

The adjustment structure includes two sets of X-axis adjustment screws 21, two sets of X-axis adjustment holes 22, two sets of Y-axis adjustment screws 25, and two sets of Y-axis adjustment holes 26. Wherein, the X-axis adjustment holes 22 pass through two slide rails 17 protruding from the bottom surface 15 of the base 12, and each group of X-axis adjustment screws 21 is locked into the X-axis adjustment holes 22 of the slide rail 17. Each Y-axis screw locking hole 26 penetrates the inner diameter tool holder 10 (or the base 12) and communicates with the fastening screw hole 24. Each group of Y-axis adjustment screws 25 is locked into the Y-axis adjustment hole 26.

When adjusting the knife holder 10, first loosen the fastening screw 23 to release the tightening state of the inner diameter knife holder 10. Because the diameter or length of the fastening screw hole 24 is larger than the diameter of the fastening screw 23, the Y-axis adjustment screw 25 abuts the fastening screw 23, and the inner diameter tool holder 10 is displaced in the direction of arrow 33 in FIG. 8. Alternatively, through the distance 29 between the two slide rails 17 and the turret 30, the X-axis adjusting screw 21 is pressed against the turret 30, and the inner diameter tool holder 10 is moved in the direction of arrow 31 in FIG. 2. Alternatively, the X and Y two-axis adjustment screws 21 and 25 are used to adjust the inner diameter tool holder 10 to rotate in the direction of arrow 35 in FIG. 8. After the adjustment is completed, the fastening screw 23 is locked again, so that the inner diameter tool holder 10 can maintain a new angle on the turret 30.

In FIGS. 5 and 9, the inner diameter turning tool 42 has a tool bar 44, and a tool head 46 is secured to the tool bar 44, and the tool head 46 is provided with a blade portion 41. An insertion hole 52 is penetrated through the center of the elastic water outlet knife cover 50 along the length direction, and a gap 54 is cut in the elastic water outlet knife cover 50 surrounding the wall of the insertion hole 52, so that the elastic water outlet knife cover 50 has a C-shaped structure design. When the elastic water outlet knife cover 50 is inserted into the tool set hole 11 of the inner diameter tool holder 10, the clamp arm 16 cooperates with the base 12 to press the elastic water outlet knife cover 50, and relatively reduces the movable space of the gap 54 to assist the elastic water outlet knife cover 50. The tool holder 44 of the inner diameter turning tool 42 is clamped.

The two sets of knife bar pressing holes 51 pass through the wall of the elastic water outlet knife cover 50 directly to the insertion hole 52, allowing a group of knife bar locking screws 53 to lock into the corresponding knife bar pressing holes 51, and the knife bar 44 penetrates into the elastic water knife. A part of the sleeve 50 exerts a pressing action, so that the knife rod 44 is fixed in the elastic water outlet knife sleeve 50.

An outer surface of the elastic water outlet knife cover 50 forms a water inlet groove 56, and the water inlet groove 56 and the gap 54 are on both sides of the insertion hole 52. A water inlet hole 58 is formed on the bottom surface of the water inlet groove 56 along the radial direction of the elastic water outlet knife cover 50, and the insertion hole 52 is communicated with the outside through the water inlet hole 58. In addition, a circle of embossing 55 on the outside of the flexible water outlet knife cover 50 facilitates the holding of the elastic water outlet knife cover 50 and smoothly enters and exits the tool set hole 11 of the inner diameter tool holder 10.

When the elastic water outlet knife cover 50 is fixed to the inner diameter tool holder 10, the water inlet groove 56 of the inner diameter turning tool 42 covers the open end of the water channel 13 to the tool set hole 11 so that the water inlet hole 58 and the water inlet groove 19 ( (See Figure 3). In this way, the fluid enters the insertion hole 52 of the elastic water outlet knife cover 50 and generates a heat conduction effect with the tool bar 44 to dissipate the heat generated by the inner diameter turning tool 42 during cutting to obtain a cooling effect.

As shown in Figures 10 and 12, the specific structure of one of the two outer tool holders 14 is roughly the same as the inner tool holder, with the following differences: First, there is no clamping arm and only the base 12 is left. The top surface of the base 12 is flat.

Secondly, there is no hole for cutting tools, and naturally there is no need for clamping screws and countersunk holes for clamping screws. However, the outer diameter tool holder 14 has an additional turning tool insertion area 79, which can be assembled into a clamping group 80 to sink into the square groove on the side of the base portion 12.

The clamping group 80 includes: a screw 64 and a pad body 66 that are locked into a screw hole 68 formed in the pad body 66 and can be displaced relative to the pad body 66; the pad body 66 is fastened to an outer diameter knife seat 14 surrounds the wall of the turning tool inserting area 79, and the limiting outer diameter turning tool 48 is assembled in the turning tool inserting area 79 of the outer diameter tool holder 14 in the radial direction of the turret 30.

Third, the outer diameter tool holder 14 also has two spray heads 60, which are arranged on the top surface of the base portion 12 and communicate with the water channel 13, and can guide the fluid to spray to the outer diameter turning tool 48.

Fourth, the outer diameter tool holder 14 has a tool water inlet hole 62 formed on the wall surface of the base portion 12 surrounding the turning tool insertion area 79 and connecting the water channel 13 and the tool water inlet hole 78 (see (Figure 3), can guide the fluid flow to the outer diameter turning tool 48.

Figures 11 and 12 show the structure of the remaining OD tool holders 14, which are approximately the same as those of the OD tool holders in Figure 10. The differences are as follows: First, the turning tool inserting area 79 sinks into the top surface of the base 12, and its staggering In the longitudinal direction of the slide rail 17.

Secondly, the number of screws 64 in the clamping group 80 has been increased from one to two, and is locked on the same side of the cushion body 66. The clamping outer diameter turning tool 48 is assembled to the outer diameter tool holder according to the axis of the turret 30 A turning tool of 14 is placed in the area 79.

Third, these spray heads 60 are disposed on the side of the base portion 12 and can also direct fluid flow to the outer diameter turning tool 48 of the turning tool inserting area 79.

In FIGS. 13 to 15, the outer diameter turning tool 48 is different from the inner diameter turning tool. The difference between the two lies in: First, there is no elastic water outlet knife cover, and the outer diameter turning tool 48 can be used alone.

Next, the outer diameter turning tool 48 has a combined structure. In other words, the cutter bar 44 and the cutter head 46 are separated, and the two are used in combination.

In the present embodiment, the tool bar 44 has two end surfaces 61, and a multi-fork groove 72 is formed on one of the two end surfaces 61. A flow channel 74 is inserted in the center of the multi-fork groove 72, and the flow channel 74 is connected to one end. The auxiliary screw hole 71 and a cutter water inlet hole 78 allow a stop screw 70 to be locked into the stop screw hole 71. The multi-fork groove 72 has a three-fork shape, and the stop screw hole 71 and the tool water inlet hole 78 are on different sides of the tool bar 44. In some embodiments, the multi-fork slot 72 may be two- or four-forked.

Next, the cutter head 46 has a cutting edge portion 41 and a center post 45. The center post 45 is hollow, and it is at a different end of the cutter head 46 from the blade part 41, and a positioning groove 47 is formed on the outer surface of the center post 45. The cutter head 46 also has a plurality of claw blocks 43. These claw blocks 43 conform to the shape of the multi-fork groove 72 and protrude around the center post 45.

When the central post 45 is inserted into the flow path 74, the claw blocks 43 are concave-convexly fitted with the multi-fork grooves 72, preventing the cutter bar 44 and the cutter head 46 from rotating with each other. The stop screw 70 penetrates into the positioning groove 47 and causes a positioning effect on the center post 45. The tool water inlet hole 78 communicates with the tool water inlet hole 62 (refer to FIGS. 10 and 11) of the outer diameter tool holder 14, and allows fluid to flow to the blade portion 41 through the inside of the outer diameter turning tool 48. Two O-rings 76 are sleeved on two O-ring grooves 49 formed in the central pillar 45. When the central pillar 45 is inserted into the flow channel 74, the O-rings 76 have a leak-proof function.
