Description
Technical field
The utility model relates to a kind of fixture, is specifically related to a kind of fixture for the machining crankshafts locating slot.
Background technology
The afterbody of bent axle need have a specific locating slot, this locating slot is to need the milling cutter mill off, the degree of accuracy and the precision of therefore processing locating slot will be very important, what use in the production and processing at present is that alignment pin on the stationary fixture blocks bent axle, interfix by pneumatic paw again, such fixed form makes easily in operating process and the bent axle displacement causes the not high quality problem of processing precision of products that serious will cause product rejection.
The utility model content
The purpose of this utility model is to provide a kind of fixture for the machining crankshafts locating slot, improves the positional precision of bent axle locating slot, has reduced fraction defective.
For realizing this purpose, the utility model has adopted following technical scheme:
A kind of fixture for the machining crankshafts locating slot, comprise base, stationary fixture, pneumatic paw and milling cutter, described milling cutter is located at described base one side, described stationary fixture is located on the described base, described pneumatic paw is located at described stationary fixture, also comprises fixed block, and described fixed block comprises fastener groove and locator card key, described fixed block is fixed in described stationary fixture side by screw, and described locator card key is located at described fastener groove one side.
Preferably, described fixed block is an irregular polygon steel plate.
Further, be provided with the stainless steel ball in the described locator card key.
Further, the diameter of described ball is 5mm.
The utility model contrast prior art has following advantage: simple in structure, easy to operate, increase the position that fixed block changes fixation workpiece, and can effectively improve the positional precision of locating slot, reduce fraction defective.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model partial enlarged drawing;
Accompanying drawing 3 is the utility model side sectional view;
Accompanying drawing 4 is specifically implemented structural representation for the utility model.
The specific embodiment
Referring now to accompanying drawing, further describe the utility model.
As shown in Figure 1, a kind of fixture for the machining crankshafts locating slot, comprise base 1, stationary fixture 2, pneumatic paw 3 and milling cutter 4, milling cutter 4 is located at base 1 one sides, and stationary fixture 2 is located on the base 1, and pneumatic paw 3 is located at stationary fixture 2, also comprise fixed block 5, fixed block 5 comprises fastener groove 51 and locator card key 52, and fixed block 5 is fixed in stationary fixture 2 sides by screw 6, and locator card key 52 is located at fastener groove 51 1 sides.
As Fig. 2, Fig. 3, shown in Figure 4, in order better to play fixation, fixed block 5 is an irregular polygon steel plate, steel plate can carry bigger pressure and guarantee in the process that lathe mills and can not rupture, service life can be longer, established a locator card key 52 in fastener groove 51 1 sides, corresponding with eccentric outer 7 footpaths of bent axle, be provided with stainless steel ball 521 in the locator card key 52, the diameter of ball 521 is 5mm, use stainless steel ball 521 can not produce any scratch to the eccentric external diameter 7 of bent axle, better guarantee product quality.
The utility model contrast prior art has following advantage: simple in structure, easy to operate, increase the position that fixed block changes fixation workpiece, and can effectively improve the positional precision of locating slot, reduce fraction defective.
Above-described the utility model embodiment does not constitute the restriction to the utility model protection domain.Any modification of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present utility model.
