A kind of novel mechanical fixture
A kind of mechanical clamp is the utility model is related to, more particularly to a kind of novel mechanical fixture.
Fixture：It is used for fixing processing object during machine-building, is allowed to occupy correct position, receives to construct or examine
The device of survey.In a broad sense, any process in technical process, for dress that is rapid, easily and safely installing workpiece
Put, all can be described as fixture.Such as welding fixture, inspection jig, assembling jig, machine tool fixture etc..Wherein machine tool fixture is the most normal
See, be often simply called fixture.In workpieces processing on lathe, to make the surface energy of workpiece reach size as defined in drawing, geometric form
Shape and with the technical requirements such as the relative-position error of other surfaces, workpiece must be installed to (positioning) before processing, clip (folder
Tightly).Fixture usually by setting element (determining correct position of the workpiece in fixture), clamping device, to knife induction element (determine
The relative position or guiding tool orientation of cutter and workpiece), indexing means (workpiece is completed several stations in once mounting
Processing, have the groups such as circular index device and rectilinear movement indexing means two class, connecting element and clamp body (clamp base)
Into.Fixture species can be divided into by handling characteristics：1. universal fixture.Such as machine vice, chuck, sucker, dividing head and revolution
Workbench etc., there is very big versatility, can preferably adapt to the conversion of manufacturing procedure and processing object, its structure has been shaped, ruler
Very little, specification seriation, wherein a kind of most of standard accessories for becoming lathe.2. specificity fixture.For certain product zero
Clamping of the part on certain procedure is needed and specially manufactured and designed, and service object is single-minded, and specific aim is very strong, generally by product manufacturing
Factory's designed, designed.Common have turning attachment, fraise jig, drill jig (guiding cutter drill or the lathe of fraising on workpiece
Fixture), the boring template machine tool fixture of boring cutter bar bore hole on workpiece (guiding) and pallet (be used for transfer line of modular machine, automatic production line of modular machine
On mobile clamping).3. flexible jig.It can replace or the special fixture of adjustment element.4. built-up jig.By not similar shape
The fixture of the standardized component composition of shape, specification and purposes, it is the single-piece often replaced suitable for trial production of new products and product, small quantities of
Production and temporary duty.
Existing fixture has the drawbacks of certain in use, should not be dismounted in maintenance process, give after-sale service personnel
Bring the trouble in assembling, work efficiency drop；Secondly, during using fixture, will be led since centering is unstable
The force unbalance of fixture is caused, makes falling for caught object, causes many unexpected generations, brings unnecessary life, property
Loss.A kind of for this reason, it is proposed that novel mechanical fixture.

Compared with prior art, the utility model has the advantages that：When assembling the novel mechanical fixture, first use
Left positioning plate is fixed in mandrel by fixed pin, then installs upper backup pad in the other end of mandrel, processed with part in
Hole loads fixture for positioning datum, then coordinates by right positioning plate in mandrel and with inner bore of part, and control lever is inserted on fixture
And with nut check, thus by clamp on workpiece.Then spring pocket is inserted between mandrel and right positioning plate again
Gap in, install pressing plate, tighten the band shoulder nut in mandrel, spring pocket be pressed into, spring pocket can play self-centering
Effect, and the axis of mandrel and the axis of workpiece are consistent, installation is complete for fixture.By setting spring pocket, can have
Effect solves the problems, such as that above-mentioned centering is unstable.It is stronger and mechanical clamp assembling is simple.A kind of machine described in the utility model
Tool fixture, equipped with spring pocket and fixed pin, can more preferably be applicable in different operating situation, bring more preferable prospect of the application.
