Abstract
The invention discloses a shaft key slot milling clamp, which solves the problem that workpiece positioning of an existing clamp is not accurate. The clamp comprises a substrate, a first clamping jaw, a second clamping jaw, a V-shaped clamping block which is arranged on the substrate and used for placing a workpiece, a first sliding rod and a second sliding rod, wherein the first clamping jaw and the second clamping jaw are respectively arranged on the two sides of the V-shaped clamping block; the upper parts of the first clamping jaw and the second clamping jaw are both clamping ends of the workpiece; the first clamping jaw is hinged to the substrate; the lower part of the second clamping jaw is fixed on the substrate; a through hole is formed in the clamping block; the through hole is internally provided with the first sliding rod; one end of the first sliding rod abuts against the first clamping jaw, and the other end of the first sliding rod abuts against one end of the second sliding rod; the second sliding rod is matched with the second clamping jaw in a sliding sleeve manner; the other end of the second sliding rod is connected with a handle; a locating plate is further arranged in the side direction of the clamping block; the locating end of the locating plate is hook-shaped; the end face of the locating end and the side face of the clamping block are on the same line. The clamp can ensure the accuracy of workpiece placement and clamping positioning.
Description
Technical field
The present invention relates to Machining Technology, be specifically related to a kind of shaft key groove milling clamper.
Background technology
fixture is widely used in the processing and manufacturing of workpiece.At present.Often there is following problem in the fixture to the processing of shaft-like workpiece keyway: in single-piece, small lot batch manufacture, because clamping position is inaccurate, often will lean on operative employee in initiating process, constantly to carry out manual synchronizing clamping device and carry out keyway milling operation again, Workpiece Machining Accuracy is poor, inefficiency.
Summary of the invention
The invention provides a kind of shaft key groove milling clamper, with what solve that existing clamping device exists, workpiece is located to inaccurate problem.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
Shaft key groove milling clamper, comprise pedestal, the first jaw and the second jaw, be arranged on the V-arrangement grip block for place work piece on pedestal, the first slide bar and the second slide bar, the first jaw and the second jaw are separately positioned on the both sides of V-arrangement grip block, the first jaw and the second jaw top are the bare terminal end of workpiece, the first jaw is articulated with pedestal, the second jaw bottom is fixed on pedestal, wherein, on described grip block, have through hole, in through hole, be provided with the first slide bar, first slide bar one end and the first jaw offset, the first slide bar other end and second slide bar one end offset, the second slide bar coordinates with the second jaw sliding sleeve, the other end of the second slide bar is connected with handle, side direction at described grip block is also provided with location-plate, the positioning end of described location-plate is hook-shaped, the end face of described positioning end and the side of grip block are on the same line.
The operation principle of this fixture is as follows: workpiece is inserted in V-arrangement grip block, because the second slide bar coordinates with the equal sliding sleeve of the second jaw, first slide bar one end and the first jaw offset, therefore promoting the second slide bar advances, the second slide bar promotes the first slide bar motion, and the first slide bar props up the first jaw bottom, will make to put outside the first jaw bottom, the middle part of the first jaw is hinged, and therefore the top of the first jaw is by interior pendulum clamping work pieces.
This fixture is inserted in process at workpiece, positioning end by location-plate is positioned, workpiece outer rim is inserted in V-arrangement grip block along the same line is concordant with grip block side, and assurance workpiece is accurately inserted in grip block, and guarantees that the geometric center of workpiece and the center of grip block are on the same line; This fixture, by V-arrangement grip block and two common holding workpieces of jaw, can be guaranteed the accuracy of shaft-like workpiece clamping position, improves the machining accuracy of workpiece.
Further, this clamping device also comprises back-moving spring, is provided with the second through hole on described grain-clamping table, and described back-moving spring is arranged in described through hole, and described back-moving spring one end is connected with the first jaw, and the back-moving spring other end is connected with the second jaw.If unclamp workpiece, back-moving spring can make the first jaw automatically reset, handled easily.
