Fig. 5 shows the universal milling machine among Fig. 1, has a tool magazine to be hinged on its front end.
Illustrated universal milling machine comprises a fixing antitorque bearing 1, and this bearing has a top horizontal guide rail 2, and along this guide rail, the same CD-ROM drive motor of headstock 3 companies is guided and carries out lengthwise movement.In that being installed on the front end of bearing, 4, one work consoles 5 of vertical guide rail are in vertical motion through being guided on this guide rail.Have a workbench 6 on this work console 5 again, this workbench can with the perpendicular horizontal guide rail (not giving diagram) of the drawing of this figure on move.The workspace of cutter and workpiece are sandwiched in zone on the workbench 6, and to constitute border 7 by a chain-dotted line represented.
From Fig. 1 to Fig. 3, can see, lateral edges place at the close milling machine in the top of workbench 6 has connected a swing arm, and this swing arm is swung around a trunnion axis 9 at the side of workbench 6, at its free end a knife rest 10 has been installed, it can 11 rotations around an axle center like this.At this above knife rest 10, one row swing blade clamping apparatus 19 separately is installed, the one end opens wide, this device can make cutter 12 insert feathering axis 13 automatically, or in the vertical rotating shaft 14 of vertical working end 15, Fig. 2 (is seen, Fig. 3) around 45 ° of surfaces of headstock 3 for basal plane rotates in working end 15.Transmission device 16(is as shown in Figure 1) can adopt the piston cylinder formula, it is hinged on the workbench 6, and its piston rod acts in the swing arm 8.Below overhanging workbench 6, a toolbox 17 is arranged, it has an end baffle 18, and knife rest is in resting position in toolbox, can protect knife rest to make it avoid contacting metal bits and stream of drill cuttings like this.
In order to change the feathering axis cutter, knife rest 10 is become replacing position shown in Figure 2 from position horizontal hunting shown in Figure 1, be to drive here by drive transmission 16, the baffle plate 18 of toolbox 17 is opened.Swing arm 8 anglec of rotation with respect to the horizontal plane is approximately 45 °, and the long-armed of this swing arm should be selected like this, bumps with workbench 6 and certain workpiece of being clipped in the workspace in oscillating motion at the knife rest 10 of a side and cutter 12 avoiding.When the upper stages edge of milling machine one side is transferred in swing arm 8 (as shown in the figure), the length of this swing arm is greater than the degree of depth of workbench 6 and the catercorner length in zone 7.Workbench 6 is along making the knife rest 10 of going up pendulum locate in such a way with the translation and the work console 5 of the perpendicular direction of drawing along vertical the moving on the guide rail 4: specific empty blade clamping apparatus 19 and feathering axis 13 are in line.This sky blade clamping apparatus 19a carries out horizontal hunting around axis 11, thereby the axis of its center line and feathering axis forms straight line.Afterwards, the feasible used cutter 12a of feed motion that has the headstock 3 of feathering axis 13 transfers on the blade clamping apparatus 19a.Return headstock 3, after cutter 12b was loosened, blade clamping apparatus 19a put back, and like this, used cutter 12a just is in plumbness.For inserting a new cutter 12b, need repeat this operation, promptly, utilize travelling table 6 and gone up the toolframe of putting 10, blade clamping apparatus 19b and feathering axis 13 are formed straight line, and utilize blade clamping apparatus 19b to forward new cutter 12a to horizontal level from its upright position, and form straight line with rotation around the swing of axis 11.Another time feed motion of headstock 3 makes new cutter 12b transfer on the feathering axis 13 from blade clamping apparatus 19b.After this replacing process, utilize swing arm 8 knife rests 10 pendulum to get back in the toolbox 17, get back to its resting position.
Fig. 3 has illustrated the cutter changing situation of vertical rotating shaft.The same with cutter changing shown in Figure 2, move and separately carry out, the adjustment of cutter 12 is to realize corresponding to the rotation of the termination of swing arm 8 by knife rest 10, the cutter furnishing vertical direction that need be changed like this, the longitudinal axis formation straight line of its center line and vertical milling head 15.In this embodiment, the motion process that the cutter used is unloaded from vertical rotating shaft and the motion process that new cutter is installed on this rotating shaft do not realized by headstock 15, but finish by moving both vertically of work console 5.Yet under the enough situation of the rotating shaft amount of feeding, even the vertical rotating shaft 14 in can leaning on feeding and returning headstock 15 is realized this motion process that is connected.
In tool magazine shown in Figure 4, two swing arms are hinged on the both sides of workbench, each swing arm all is made up of two levers 30 and 31, and they connect by coupling arrangement 32 in the middle of.A linear actuator 33, for example a cylinder is connected with a support 34, and this support is installed in down on the lever 30, and this device 33 is also put lever 30 to shown in the chain-dotted line from the lower position shown in the solid line and is changed the position.Another linear actuator 35 is hinged on down on the lever 30, and its piston rod is connected on the support 36, and this support stretches out from the side of upper lever 31.At the free end of this upper lever 31, a knife rest 37 has been installed so that can be once around its longitudinal axis Rotate 180 °.In this tool magazine embodiment, this knife rest 37 has two row's blade clamping apparatus 39, and they are installed axisymmetricly, and this design is compared with the tool magazine of Fig. 1 to Fig. 3, and the cutter 40 and 41 of twice can be arranged.As shown in the figure, utilize this tool magazine, only the cutter changing on the vertical rotating shaft 14 is fallen, this practice makes more the structure of converting mechanism simplify greatly.In fact as can be seen, in practice, the cutter on the vertical rotating shaft 14 that need change usually will be more than the required cutter of changing on the feathering axis 13.Therefore, for the operation of a kind of automaton, utilizing programme controlled mode just to change cutter on the vertical rotating shaft, usually is more favourable, and can increase the capacity of tool magazine and be twice.Because vertical headstock will be narrower than headstock 3 usually in order to hold the fore-end of feathering axis 13, therefore, that blade clamping apparatus 39 can be installed on knife rest 37 is compacter, and in the process of cutter changing, vertical headstock 15 can not collide with the cutter on the adjacent blade clamping apparatus among the same row.For feathering axis and the cutter that need change at any special time, adopt same compactness to install to blade clamping apparatus, must need the cutter changed together to move on to one respectively so at any time and change on the position, bump with cutter adjacent in the tool magazine with the headstock of avoiding broad together with their blade clamping apparatus.Yet moving respectively of this blade clamping apparatus needs a kind of comparatively complicated transmission mechanism.For the blade clamping apparatus that will be fixed on the rotatable 180 ° knife rest is located exactly, this knife rest also can have a matrix part, for example, and part shown in the dotted line when knife rest swings in inactive state.
Embodiment in 5 with reference to the accompanying drawings, being some blade clamping apparatus that a row is installed on the knife rest 20 can be rotated around an axis 22 along this knife rest longitudinal extension separately.Knife rest 20 is installed on the beveled end member 23 of a swing arm 24, and the free end of this swing arm is hinged on the front bulkhead 25 of workbench 6, and it can be swung around a trunnion axis 26 like this.In order to change a cutter, this swing arm 24 can utilize a transmission device (not shown), for example a kind of piston horizontal pendulum to a vertical means according to Fig. 1, thus knife rest 20 is together with flatly launching before headstock once row's blade clamping apparatus 21 and cutter in the above 12.Utilize suitably moving of work console 5, workbench 6 and headstock 3 and moving respectively of rotating shaft 13 and 14, and utilize the rotation of each blade clamping apparatus 21 to move, in each case, the cutter of having used can be taken off and change a new cutter from level or vertical rotating shaft.
The present invention is not limited only to the scope of above-mentioned example embodiment.For example, swing arm can comprise two or more parts, and this part can adopt the telescopic interlocking thus can its length of conversion, has so just improved the stationkeeping ability in original state and cutter changing state.At last, in order to ensure reliable cutter changing process, provide a kind of locking or clamping device, this device acts in for example swing arm, and knife rest is fixed on its initial position, especially puts at it and carries out on the position of cutter changing.
