Description
Technical field
The utility model belongs to field of mechanical technique, relates in particular to a kind of keyway broach Milling Process special fixture.
Background technology
Keyway broach, makes in machinery manufacturing industry, is mainly used in the high speed compound cutting element of processing automobile, motorcycle accessories bore.The structure entirety of keyway broach is strip, and comprise shank section and cutter tooth portion, in cutter tooth portion, homonymy is forward set side by side with multiple cutter tooth.In the process of keyway broach, for the geometry of vertical knee-type milling machine roughing keyway broach, comprise the roughing of the wide and shank of tooth stage rank, chip pocket, end face, key, require each end face corase grind of workpiece, and there is good geometric accuracy.In prior art, adopt traditional processing technology, when carrying out milling roughing to keyway broach each several part, once can only process a workpiece, and Milling Process operation each time, need clamping, positioning workpieces again, cause that technique is loaded down with trivial details, location is inaccurate, machining accuracy is poor, labour intensity is large, production efficiency is low.
Summary of the invention
The purpose of this utility model is overcome above-mentioned shortcoming and provide a kind of accurate positioning, reliable clamping, and structure is simple, be easy to manufacture, production efficiency is high, machining accuracy and uniformity good, and the keyway broach Milling Process special fixture of the Milling Process operation of keyway broach can be common to.
The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions:
Keyway broach Milling Process special fixture of the present utility model, comprise chuck body, some compression cushion blocks, wherein: described chuck body is provided with groove A and groove B, some compression cushion blocks are positioned at groove, and each compression cushion block is connected with chuck body by some hold-down bolts.
Above-mentioned keyway broach Milling Process special fixture, wherein: described compression cushion block is 2-3 part.
Above-mentioned keyway broach Milling Process special fixture, wherein: the working face of described each compression cushion block is parallel to each other.
Above-mentioned keyway broach Milling Process special fixture, wherein: horizontal location face and the perpendicular positioning face of described chuck body are orthogonal.
The utility model compared with prior art has obvious advantage and beneficial effect.From above technical scheme, chuck body is provided with some compression cushion blocks, and the working face of each compression cushion block is parallel to each other, and to ensure fixture accurate positioning, reliable clamping, and Grouped Jobs can be clamped.Each compression cushion block is connected with chuck body by some hold-down bolts, and workpiece pressing, the mode compressed by compressing cushion block multiple spot ensures reliable clamping, and controls the pinching deformation of workpiece preferably, thus ensure that machining accuracy.
In a word, the utility model has the following advantages:
1, this fixture accurate positioning, reliable clamping, structure is simple, is easy to manufacture, and can be common to the Milling Process operation of keyway broach;
2, operate, easy to adjust, easily grasp, machining accuracy and uniformity better;
3, because this fixture can realize processed in batches, decrease the clamping times of workpiece, substantially increase production efficiency relative to single-piece work, and make workpiece have good uniformity, reduce difficulty and the workload of subsequent handling, overall efficiency improves more than 3 times.

detailed description of the invention:
Below in conjunction with accompanying drawing and preferred embodiment, to according to keyway broach Milling Process special fixture detailed description of the invention, structure, feature and the effect thereof that the utility model proposes, be described in detail as follows.
See Fig. 1 to Fig. 3, keyway broach Milling Process special fixture of the present utility model, comprise chuck body 1, some compression cushion blocks 3, wherein: described chuck body 1 is provided with groove A4 and groove B5, some compression cushion blocks 3 are positioned at groove A4, and each compression cushion block 3 is connected with chuck body 1 by some hold-down bolts 2.Described compression cushion block 3 is 2-3 part.The working face of described each compression cushion block 3 is parallel to each other.Horizontal location face and the perpendicular positioning face of described chuck body 1 are orthogonal.
During use, see Fig. 4 to Fig. 6, workpiece 6 is put in groups the groove A4 of chuck body 1, after coarse positioning, suitably tighten hold-down bolt 2, by the pre-clamping work pieces 6 of clamping backing plate, by some hold-down bolt 2 workpiece pressings 6, realize multiple spot and compress, then with copper rod beat gently workpiece 6 above and side, workpiece 6 bottom surface is contacted with chuck body 1, end face is as far as possible concordant, then tightens hold-down bolt 2 clamping work pieces 6, processes.
The width of the groove A4 of the length of chuck body 1, width and clamping workpiece 6 is determined according to machine tool travel and workpiece 6 size.Horizontal location face and the perpendicular positioning face of chuck body 1 are orthogonal, and the working face of each compression cushion block 3 is parallel to each other, to ensure fixture accurate positioning, reliable clamping.Fixture is arranged on platen face during use, and levelling locating surface, make that horizontal location face is parallel with work top, perpendicular positioning face is parallel with workbench side-to-side movement, then by the groove B5 at two ends in chuck body 1, fixture of the present utility model is fixed on platen with T-slot bolt.Because the locating surface of fixture and the direction of motion of workbench are distinguished parallel, thus ensure that the geometric accuracy of machined surface can reach technological requirement.Because workpiece 6 is elongate articles, adopt the mode compressed by compressing cushion block 3 multiple spot to ensure reliable clamping, and control the pinching deformation of workpiece 6 preferably, thus ensure that machining accuracy.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, anyly do not depart from technical solutions of the utility model content, the any simple modification done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
