Abstract
The invention discloses a clamp for shaft flat grinding, which solves the problems of an existing shaft clamp that the clamping and positioning are not stable and the using of the clamp is limited. The clamp comprises a substrate, wherein the substrate is provided with a first clamping block and a second clamping block arranged opposite to the first clamping block; the first clamping block is provided with two connecting shafts; the two connecting shafts are positioned on the same side face; the second clamping block is penetrated on the two connecting shafts; a clamping portion of a workpiece is formed between the first clamping block and the second clamping block; a reset spring is arranged on each connecting shaft and positioned between the two clamping blocks; the side face, at the back of the first clamping block, of the second clamping block is provided with a compressing cam abutting against the second clamping block; a locating shaft is arranged on the substrate and positioned at the geometric center of the clamping portion; at least three clamping jaws are uniformly distributed on the circumference of the locating shaft. The clamp is stable to clamp and position, and has practicability.
Description
Technical field
The present invention relates to Machining Technology, be specifically related to a kind of fixture for axle class plain grinding.
Background technology
Fixture is widely used in the processing and manufacturing of workpiece.The plain grinding processing of shaft-like workpiece is the basis of following process, and its machining accuracy is larger on the processing impact of subsequent workpiece, therefore, the plain grinding processing of shaft-like workpiece is had to certain required precision.At present, for the fixture of axle class plain grinding, often have the following disadvantages: 1. during clamping, generally only with alignment pin location, owing to having gap between the inner circle of shaft-like workpiece and alignment pin, therefore often cause workpiece to rock bias, reduce machining accuracy; Therefore 2. fixture clamping part is unadjustable, and fixture can only clamp a kind of workpiece of specific dimensions, and fixture utilization rate is low, it is limited to use.
Summary of the invention
The invention provides a kind of fixture for axle class plain grinding, to solve, the clamping position that existing axle class fixture exists is unstable, fixture is used limited problem.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
Fixture for axle class plain grinding, comprise pedestal, the second clamp that pedestal is provided with the first clamp and is oppositely arranged with the first clamp, the first clamp is provided with two connecting axles, two connecting axles are positioned at same side, described the second clamp is located on two connecting axles, between the first clamp and the second clamp, form the clamping part of workpiece, on each connecting axle, between two clamps, be equipped with back-moving spring, the the second clamp dorsad side of the first clamp is provided with the compression cam offseting with the second clamp, the geometric center place that is positioned at clamping part on pedestal is provided with locating shaft, circumferential uniform at least three claws of locating shaft.
Beneficial effect of the present invention: because this fixture the second clamp is arranged on two connecting axles, therefore, when the first clamp has the second clamp to coordinate holding workpiece, can regulate the distance between the second clamp and the first clamp according to the diameter of shaft-like workpiece, and then regulate the space of clamping part to realize the clamping of different size workpiece; Due to circumferential uniform at least three claws at locating shaft, therefore, when shaft-like workpiece is located, claw will block the inner circle of shaft-like workpiece, and claw is uniform, can guarantee the stability that holds, and workpiece can not produce and rock, and can improve the machining accuracy of workpiece.
Further, the first clamp and the second clamp side direction are respectively equipped with towards identical V-shaped groove, and described retaining part is between two V-shaped grooves.During holding workpiece, the cylindrical that is blocked shaft-like workpiece by the groove edge of two V-shaped grooves carries out clamping position to workpiece, can further guarantee the stability of clamping.
Accompanying drawing explanation
Fig. 1 is that the present invention is for the structural representation of the fixture embodiment of axle class plain grinding;
Fig. 2 is the top view that Fig. 1 embodiment axis class polishes fixture.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
As Fig. 1, shown in Fig. 2, this fixture comprises pedestal 1, the second clamp 3 that pedestal 1 is provided with the first clamp 2 and is oppositely arranged with the first clamp 2, the first clamp 2 is provided with two connecting axles 5, two connecting axles are positioned at same side, the second clamp 3 is located on two connecting axles, between the first clamp 2 and the second clamp 3, form the clamping part of workpiece, the first clamp 2 and the second clamp 3 side direction are respectively equipped with towards identical V-shaped groove 8, retaining part is between two V-shaped grooves, on each connecting axle, between two clamps, be equipped with back-moving spring 6, the the second clamp 3 dorsad side of the first clamp 2 is provided with the compression cam 4 offseting with the second clamp 3, compressing cam is connected with handle, the geometric center place that is positioned at clamping part on pedestal 1 is provided with locating shaft 7, circumferential uniform three claws of locating shaft 7.
Claims (2)
1. for the fixture of axle class plain grinding, comprise pedestal, the second clamp that pedestal is provided with the first clamp and is oppositely arranged with the first clamp, it is characterized in that, the first clamp is provided with two connecting axles, two connecting axles are positioned at same side, described the second clamp is located on two connecting axles, between the first clamp and the second clamp, form the clamping part of workpiece, on each connecting axle, between two clamps, be equipped with back-moving spring, the the second clamp dorsad side of the first clamp is provided with the compression cam offseting with the second clamp, the geometric center place that is positioned at clamping part on pedestal is provided with locating shaft, circumferential uniform at least three claws of locating shaft.
