Abstract
The invention relates to a blind-hole nesting back-pushing type cutting device which is arranged on a special machine tool or a lathe and is used for nesting processing of blind-hole parts. The invention comprises a basic seat arranged on a machine work table or a lather slipway and a cutting-tool array fixedly clamped on the basic seat. An annular cutting-tool rest which does an arc movement is respectively articulated with the front end and the back end of the cutting-tool array. A cutting body is fixedly arranged on the annular cutting-tool rest. One end of a hinge rod is articulated with the arc top end of the annular cutting-tool rest, and the other end of the hinge rod is articulated with a sliding rod which is connected with an output end of a feeding box. The sliding rod dose a straight-line feeding movement in virtue of the feeding box. The bottom size accuracy and the surface accuracy of the manufactured blind-hole are higher than that manufactured by the nesting processing method. The invention has higher cutting efficiency, can completely preserve a material core and save materials, and has no damage to the processed internal surface.
Description
Technical field
The present invention relates to a kind of being installed on special purpose machine tool or the lathe blind hole part is carried out jacking processing and cuts off the non-penetrated hole jacking back push type cutting device of expecting core, especially be fit to the high high pressure deep hole cylinder body of required precision, the processing of special alloy deep hole cylinder body.
Background technology
At present, the jacking mode is adopted in domestic processing to the blind hole part more.Its processing cost is low, efficient is high, and can also save the blanking core and make other part, be a great problem but take out the material core behind the jacking.Conventional method is that pincers worker will expect that with instrument core interrupts, and will expect that again core takes out.This mode efficient is very low, and is difficult to the material core is interrupted from root, can't back chipping.Run into the blind hole of alloy material, can only little by little interrupt taking-up to the material core, destroyed the material core and also caused easily processing the destruction of endoporus.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art and provide a kind of blind hole processing mode that adopts efficient economizing to solve the material core and cut off problem, can finish how much requirements of drawing at the bottom of to the hole, higher surface accuracy can also be arranged, the non-penetrated hole jacking back push type cutting device of complete reservation material core.
The object of the present invention is achieved like this: comprise the pedestal that is installed on special plane workbench or the lathe slide unit, fix to clamp the blade row on pedestal, the two point articulated ring-like knife rests that the movement in a curve done is arranged before and after on blade row, on ring-like knife rest, be mounted with cutter hub, the end that hinge-rod is arranged at the arc top upper hinge of ring-like knife rest, the other end and the sliding bar of hinge-rod are hinged, sliding bar is connected with the output of feed box, and sliding bar promotes to do the straight-line feed motion by feed box.
Feed box comprises bearing, is installed in the nut shaft on the bearing, and an end of nut shaft is fixedlyed connected with handwheel, and the other end of nut shaft is connected with screw flight, and screw rod is connected with sliding bar.
Blade row is positioned at a side of pedestal, and feed box is positioned at the opposite side of pedestal, and sliding bar passes pedestal and is connected with screw rod.
On blade row, fix the push rod lid of promising sliding bar guiding.
The cutter hub blade is 90 ° of cutting knifes of three swords, and main cutting edge and cutter hub are 15 ° of drift angles, and the cutter hub afterbody is cylindric, is fixed on the position of ring-like knife rest arc top.
The present invention has following advantage
1, the blind hole bottom that processes, dimensional accuracy and surface accuracy all are higher than the jacking mode and process the precision level that can reach, and can be used as semifinishing and use.
2, has higher cut-out efficient.
3, can be complete retain the material core, saved material.
4, can not damage the inner surface of having processed.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a structure of the cutter body schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, the present invention includes the pedestal 7 that is installed on special plane workbench or the lathe slide unit, fix to clamp the blade row 6 on pedestal 7, the two point articulated ring-like knife rests 2 that the movement in a curve done is arranged before and after on blade row 6, on ring-like knife rest 2, be mounted with cutter hub 1, the end that hinge-rod 3 is arranged at the arc top upper hinge of ring-like knife rest 2, the other end of hinge-rod 3 and sliding bar 4 are hinged, and sliding bar 4 is connected with the output of feed box 11, and sliding bar 4 promotes to do the straight-line feed motion by feed box 11.
Feed box 11 comprises bearing 10, is installed in the nut shaft 9 on the bearing 10, and an end of nut shaft 9 is fixedlyed connected with handwheel 12, and the other end of nut shaft 9 is threaded with screw rod 8, and screw rod 8 is connected with sliding bar 4.When handwheel 12 and nut shaft 9 rotated, screw rod 8 moving linearlies that are threaded with nut shaft 9 promoted sliding bar 4 and also do the straight-line feed motion.
Blade row 6 is positioned at a side of pedestal 7, and feed box 11 is positioned at the opposite side of pedestal 7, and sliding bar 4 passes pedestal 7 and is connected with screw rod 8.
On blade row 6, fix the push rod lid 5 of promising sliding bar 4 guiding.Push rod lid 5 also can be called fairlead, and sliding bar 4 is through in the fairlead, and fairlead plays guide effect.
As shown in Figure 2, cutter hub 1 blade is 90 ° of cutting knifes of three swords, and main cutting edge and cutter hub 1 are 15 ° of drift angles, and cutter hub 1 afterbody is cylindric, is fixed on the position of ring-like knife rest 2 arc tops.
The present invention is installed in pedestal 7 on special plane workbench or the lathe slide unit, and pedestal 7 clamps and fixing blade row 6.Feed box 11 is contained in the afterbody of blade row 6, and feed box is made up of nut shaft 9 and bearing 10, and an end connects the other end and connects with screw rod 8 with handwheel 12, and screw rod 8 has been formed catch bar with sliding bar 4, and push rod lid 5 is fixed on and is sliding bar 4 guiding on the blade row 6.The cutter part is made up of cutter hub 1 and ring-like knife rest 2, and ring-like knife rest 2 two-end-points and blade row 6 are hinged, and an end of arc top and hinge-rod 3 is hinged, and sliding bar 4 is hinged with the other end of hinge-rod 3.Add man-hour workpiece 14 with the lathe main axis rotation, reverse handwheel 12 nut shafts 9 rotates thereupon, screw rod 8 is released to workpiece 14 directions, it is that circular motion is done in the center of circle with the pin joint of blade row 6 and ring-like knife rest 2 that sliding bar 4 is subjected to the effect of screw rod 8 to promote hinge-rod 3, ring-like knife rest 2, cutter hub 1, centering angle during near 90 ° material core 13 both be cut off.
Mounting base on special plane workbench or lathe slide plate is equipped with the cut-out blade row that is consistent with jacking blade row size in the pedestal of two bodies about dividing, and the handwheel of feed box connects with the feed nut axle.Catch bar one end is that screw rod connects with the feed nut axle, and to be rectangular shaft accurately slided and hinged with hinge-rod along the workpiece direction by the effect of blade row guider the other end.Hinge-rod and ring-like knife rest are hinged, and the special metals cutter head is housed on the knife rest, and knife rest two-end-point and blade row are hinged.Device start, workpiece is with the lathe main axis rotation.Rotate handwheel, feed nut rotates with handwheel, and screw rod is promoted to the workpiece direction, and hinge-rod promotes ring-like knife rest and moves along an arc direction under the screw rod thrust, and cutter is done the cutting of arc direction with ring-like knife rest.The material core both was cut off when knife rest was fed to centering angle near 90 °.Withdraw from blade row and take out the material core, this operation finishes.
