Description
Technical field
This utility model relates to grinding machine field, particularly to a kind of fixture for grinding machine.
Background technology
Grinding machine is to utilize grinding tool that surface of the work is carried out the lathe of grinding.Most grinding machine is that the emery wheel using high speed rotating carries out grinding, and workpiece needs to utilize special fixture that piece-holder is stable processing when.
At present; processing some lock units when; owing to the medial aperture of lock unit is the structure of spline; stable in order to ensure it is fixed, it will usually utilizes just lock unit to be stuck in above the clamping joint of spline structure, then utilizes end face nut screwing clamping; fixture under this structure; although the stable rotation driving lock unit that can be stable, can there is certain friction, cause the abrasion on surface in its lock unit and clamping joint during inserting and extracting between the two.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is the fixture for grinding machine providing a kind of clamping relatively stable.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of fixture for grinding machine, including the chuck body being connected with grinding machine, it is equipped with tensioning shaft in described chuck body, described tensioning shaft is by realizing axial motion with the threaded engagement of chuck body, described tensioning shaft outer cover is provided with disc spring, the latch for clamping lock unit it is integrally formed with outside described disc spring, be integrally formed with on described tensioning shaft with disc spring inside conflict fixture block, the internal ring of described disc spring is connected with described chuck body.
Pass through technique scheme, owing to conflicting with chuck body in disc spring side, therefore disc spring is after by the extruding of briquetting, it can expand toward outside, shifted from butterfly toward flat shape, like this just can allow the clamping that the spline inside latch and lock unit is stable, it is ensured that both can keep relative stablizing by mutually extruding.
This utility model is further arranged to: described latch quantity is three and is uniformly distributed along described disc spring outer surface.
By technique scheme, three reciprocal latch structure are relatively simple, it is possible to the relatively stable card is caught, and can most probable latch quantity be preferably minimized, it is ensured that the stable folding and unfolding of disc spring while ensureing structure.
This utility model is further arranged to: the cross section of described latch is rectangle.
By technique scheme, rectangular cross section ensure with lock unit above clamping relatively stable, reduce the gap between mutual clamping as far as possible, it is ensured that the stability of junction.
This utility model is further arranged to: described disc spring is made up of steel alloy.
By technique scheme, the structure of steel alloy is relatively stable, possesses enough elasticity, it is possible to ensure that disc spring is shunk the most for a long time.
This utility model is further arranged to: described fixture block is annular.
By technique scheme, the fixture block of annular more average on stress, it is possible to uniform drive disc spring to expand, it is ensured that overall stabilized driving.
In sum, what this utility model in contrast to prior art has the beneficial effect that the expansion structure utilizing disc spring and fixture block, it is possible to the less gap eliminated between clamping joint and lock unit, it is ensured that being stably connected with between the two.The most this clamping is the quickest, it is only necessary to is turned inside by tensioning shaft and just can complete tensioning, the most quickly.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
A kind of fixture for grinding machine, including the chuck body 1 being connected with grinding machine, chuck body 1 is cylindrical, the clamping joint of hollow it is integrally formed with on chuck body 1 one end, chuck body 1 other end is for being connected with driving head on grinding machine, grinding machine can drive chuck body 1 to rotate, thus drives chuck body 1 workpiece above to rotate.
Such as Fig. 1, tensioning shaft 2 it is equipped with in chuck body 1, tensioning shaft 2 one end is inserted into inside chuck body 1, tensioning shaft 2 is by realizing axial motion with the threaded engagement of chuck body 1, it is square toes 22 that tensioning shaft 2 is positioned at the one end outside chuck body 1, can engage with spanner so that the drive tensioning shaft 2 that spanner can be stable rotates, tensioning shaft 2 is integrally formed with an annular fixture block 21.
Tensioning shaft 2 outer cover is provided with disc spring 3, the shape of disc spring 3 is as shown in Figure 2, the latch 31 for clamping lock unit it is integrally formed with outside disc spring 3, the quantity of latch 31 has three and is uniformly distributed along disc spring 3 outer surface, three latch 31 structures are relatively simple, relatively stable can be blocked and be caught, can most probable latch 31 quantity be preferably minimized while ensureing structure, it is ensured that the stable folding and unfolding of disc spring 3.Wherein, the cross section of latch 31 is rectangle, rectangular cross section ensure with lock unit above clamping relatively stable, reduce the gap between mutual clamping as far as possible, it is ensured that the stability of junction.Disc spring 3 is made up of steel alloy, and the structure of steel alloy is relatively stable, possesses enough elasticity, it is possible to ensures that disc spring 3 is stable and shrinks for a long time.
Installing when, the internal ring of disc spring 3 is connected with chuck body 1 one.This fixture for grinding machine is mounted in above grinding machine work when, the when of utilizing its clamping lock unit, its work process is as follows: be enclosed within by lock unit outside jump ring, then tensioning shaft 2 is inserted in jump ring, overlap upper ejector lever the most again on square toes 22 and tensioning shaft 2 spiral is entered in chuck body 1, the most progressively have an effect, by fixture block 21, disc spring 3 is opened and make it ensure that be connected stablizes with the extruding of lock unit inwall.Unload lower ejector lever afterwards, start grinding machine and just can start machined.Its unloading process has only to above-mentioned steps reverse operating one time, it becomes possible to realize, and whole to remove and install process very convenient, quick, and clamps relatively stable.
The above is only exemplary embodiment of the present utility model, and not for limiting protection domain of the present utility model, protection domain of the present utility model is determined by appended claim.
