Positioning clamp for machining triangular workpiece

Abstract

The invention discloses a positioning clamp for machining a triangular workpiece. The positioning clamp has a clamping mechanism that is connected to the interior of a mounting groove. The clamping mechanism comprises a mounting base, a first clamping piece and a second clamping piece; the mounting base is embedded into the mounting groove; the mounting base is rotatably connected with the first clamping piece and the second clamping piece, torsional springs are arranged at the rotary joints of the mounting base and the first clamping piece and the second clamping piece, the first clamping piece and the second clamping piece are symmetrically arranged, and the first clamping piece and the second clamping piece are used for clamping and fixing the triangular workpiece from two inclined planes; a second clamping seat is used for supporting and fixing the triangular workpiece from the flat plane; the two side faces of the triangular workpiece can be positioned through the clamping mechanism, then the second clamping seat is used for positioning the flat plane, and therefore three-face positioning is achieved, the positioning face is wide, the positioning structure is more stable and firmer, and the problem that the triangular workpiece is difficult to position is solved.

Description

technical field [0001] The invention belongs to the technical field of machine tool fixtures, in particular to a positioning fixture for triangular workpiece processing. Background technique [0002] Machine tool fixture is a device used to clamp the workpiece on the machine tool; it is characterized by compact structure, quick, convenient and labor-saving operation, and can ensure high machining accuracy and production efficiency; it is in contact with the positioning datum of the workpiece and used for Determine the correct position of the workpiece in the fixture, so as to ensure the relative correct position of the workpiece relative to the tool and the machining movement of the machine tool during processing; at present, the machine tool fixture is mainly a sliding clamping seat and a fixed clamping seat, two clamping The seat cooperates to clamp the workpiece from both sides; [0003] When clamping and positioning a triangular workpiece, since the current fixture can ...

AI Technical Summary

Problems solved by technology

[0003] When clamping and positioning a triangular workpiece, since the current fixture can only fix two parallel and symmetrical surfaces, the current fixture can effectively locate the triangular workpiece, and can only be replaced with a special fixture as a whole, resulting in an increase in production costs. The production process, and the special fixture needs to be operated one by one, the operation is complicated
