Movable vice body clamping tool for bench vices

Abstract

The invention relates to a movable vice body clamping tool for bench vices, which comprises a base, an abutting block, a bracket, a limiting component and an abutting cylinder, wherein the base can be fixed on a machine tool, the abutting block is fixed at the rear end part of the base, the bracket is fixed at the front end part of the base, the limiting component is arranged on the base and used for positioning a movable guide rail, the abutting cylinder is fixed on the bracket, the base is provided with a working plane matched with the bottom surface of a movable vice body, the bottom surface of the movable vice body is arranged on the base, the abutting block is protruded out of the working plane, the abutting block is provided with an abutting surface to be parallel to and in abutting fit with the rear end face of the movable vice body, and the abutting cylinder is provided with a piston rod for being abutted against the front end face of the movable vice body, and the axial lead of the piston rod is inclined and extends backwards and downwards. The clamping tool disclosed by the invention can rapidly and steadily clamp a movable vice body, so that when a machine tool carries out machining on the movable vice body, the machine tool or the movable vice body can not shake, thereby improving the machining accuracy of the movable vice body.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a clamping tool for a movable vise body of a bench vise. Background technique [0002] attached Figures 1 to 6 The internal structure of a common bench vise is shown, which includes a base 1, a fixed tong body 2 fixed on the base 1, a movable tong body 3 partially passing through the interior of the fixed tong body 2, and the interior of the fixed tong body 2 has The through groove 23 that runs through front and back, the bottom of the through groove 23 forms the support guide rail 24, and its movable clamp body 3 has the movable guide rail 33 that is positioned at the through groove 23 and can slide freely on the support guide rail 24, and the left and right sides of the movable guide rail 33 The surface has a smooth guide surface 331 that needs to be matched with the through groove 23 of the fixed guide rail. The rear end of the movable guide rail 33 has a rear end surface 332 that is incl...

Problems solved by technology

[0003] In the prior art, the processing of the movable vise body 3 of the bench vise is carried out on an ordinary milling machine or lathe. Since the movable vise body 3 is not a regular part, it is not easy to clamp it with ordinary clamps. Usually its processing accuracy is too low when the movable clamp body 3 is processed, and some surfaces that require higher processing accuracy, such as the guide surfaces 331 located on both sides of the movable guide rail 33 of the movable clamp body 3, if ordinary processing fixtures are used, then Can cause friction between the left and right side walls of the movable guide rail 33 and the left and right side inner walls of the through groove 23, the sliding stroke of the movable tong body 3 inside the fixed tong body 2 will be hindered, if the movable tong body is clamped twice, and Carrying out milling processing on the two guide surfaces separately, the processing process is cumbersome, and the cumulative error of each plane is relatively large, it is easy to cause the guide surfaces 331 on both sides of the movable clamp body moving guide rail 33 to be non-parallel
