The fixture is aligned on a machine tool, is convenient for fixation, can realize automatic center determination of workpieces with different diameters, can realize the machining of holes with any angle in the radial direction, and is suitable for linear cutting, ignition sparks, milling machines, drilling machines and the like.

Description

Axle class radial porous clamp for machining

Technical field

The present invention relates to mechanical field, particularly relate to a kind of axle class radial porous clamp for machining.

Background technology

Along with the growing of commodity economy and the raising gradually of scientific and technological level, speed, benefit have become the focus that everybody pays close attention to.The technological innovation of machining class is also extremely urgent, makes large quantities of numerical control devices instead of traditional equipment, is traditional processing just genuine in place?

When adopting wire cutting machine tool to process the square hole on certain Fig. 1 workpiece aborning; ensure the symmetrical clamping of square hole and conical rod; often there will be following problem: (1) Linear cut exists much inconvenience when centering; the position processed is on processing axis; the symmetrical precision of original wire hole is not often very high, be used as lathe automatically divide in fabrication hole can not ensure machining accuracy.(2) some part used in the past, and existing square hole can need again to expand because of crimp, with original hole as a point mesopore, can not bring difficulty to processing.(3), when the appearance and size of workpiece is different, often processing once will to a cutter, and spended time is more, and machining accuracy is lower.(4) circular hole is vertical with square hole, and rotate with omnipotent index dial and realize, platen does not have enough spaces.(5) be much necessary in processing to design and produce a kind of simple frock adapting to the axle class processing of different-diameter, during cutting square hole, in can realizing easily point, levelling row and any rotation, namely ensure working (machining) efficiency and symmetrical precision, make again the structure of fixture simple and easy to make.

For the processing of this kind of round piece square hole, in first will dividing accurately.Present numerically controlled wire cutting machine has endoporus automatically to divide middle function, tool setting speed can be improved and symmetry accurate.When generally cutting square hole, can at working position subdrilling through wires hole, as shown in Figure 1, when utilizing this hole to carry out point middle, the precision of symmetry and perpendicularity finally determines the positional precision of institute's machining hole.Must be accurate when this just requires driller's skill hole, but the borehole accuracy on similar knife bar one similar round workpiece is often difficult to ensure, and the error of pincers worker drilling machine boring, generally at more than 0.1mm, is difficult to ensure final technological requirement.For this kind of problem, in real work often clamping workpiece well after, put on molybdenum filament, although precision has certain guarantee, speed is slow.In order to prevent the crooked of square hole and round bar, also parallel with machine tool guideway by beating table adjustment round bar axis, and often process a workpiece and will again once, namely waste time and energy by centering, a middle function of automatically dividing for lathe is not also fully played.If piece count is more, working (machining) efficiency seems very low.

For the processing of the circular hole on this kind of round piece, ensure that circular hole has just become top priority with square hole is vertical.Except machining center with except utilizing special purpose machine tool, omnipotent index dial is often utilized to assist realization in reality, although can accurately rotate to 90 °, ensure crudy, but require that operator can be familiar with the operation of omnipotent index dial, and the cost that is conscientious, careful, that secondly drop into that works is also higher, platen must can place the space of index dial.

Summary of the invention

The object of the invention is to for processing in prior art that certain axial workpiece radial hole efficiency is low, the problem of deficiency in economic performance, the axle class radial porous clamp for machining providing a kind of structure simple, practical, easy to operate.

A kind of axle class radial porous clamp for machining, comprises base, base is fixed with two for supporting the first support column of axle to be processed, one end of axle to be processed is provided with the protractor for measuring for machining hole angle.

Further, axle class radial porous clamp for machining as above, comprise fixed head, one end of described fixed head is fixed on base by the second support column, the other end is provided with a breach, be connected with the 3rd support column in this indentation, there by the first screw, the bottom of the 3rd support column is fixed on base.

Further, axle class radial porous clamp for machining as above, described first support column is y-type structure.

Beneficial effect:

Fixture is centering, convenient fixing on lathe, can realize the workpiece of different-diameter, automatically determine center; The processing being mutually unspecified angle hole can be realized in radial direction; Be suitable for Linear cut, some spark, milling machine, drilling machine etc.

Detailed description of the invention

For making the object, technical solutions and advantages of the present invention clearly, below technical scheme in the present invention be clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.

As shown in Figure 2, axle class radial porous clamp for machining provided by the invention comprises two Y type support columns 3 for supporting axle to be processed, and these two support columns 3 are fixed on the two ends of base by locking nut 4; Move in process for preventing axle 2 to be processed, with fixed head 1 at two support columns (the second support column 6, second support column 13) workpiece pressing, radial hole is at any angle mutually in order to realize processing on workpiece, in one end of axle to be processed, fixed by protractor 8 with the 4th support column 7, the bottom of two the 4th support columns 7 is all fixed on base 5 by locking nut 4.The horizontal amount of described protractor 8 being hinged with the first turning cylinder 11, first turning cylinder 11 is hinged on the second turning cylinder 10, the second turning cylinder 10 is arranged porose, is inserted with bearing pin 9 in hole.

Operation principle:

As shown in Figure 2, fixture placed, adjust, be fixed on platen.Machining shaft 2 is fixed on " Y " t shore by fixed head 1.First process radial hole at left end, dimensional requirement and alignment pin 9 prepare.Unscrew the screw 12 of the 3rd support column 13 one end, axle is turned around be positioned over " Y;; on t shore; be connected with protractor by alignment pin, turning cylinder, rotate the first turning cylinder 11 adjustment amount hornwork to required angle, tighten the screw of the 3rd support column 13; lock shaft, just can process next radial hole.Fixture of the present invention also can be used as single hole processing and uses.

Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
