Scribing clamp for working table surface

Abstract

The invention discloses a scribing clamp for a working table surface and belongs to the technical field of machine tool clamps. The scribing clamp for the working table surface comprises a base plate, a positioning base, a plug pin, positioning blocks, locking handles, a limiting pin, cushion blocks and an eccentric shaft. The base plate is horizontally arranged. The positioning base is fixed to the middle left portion of the upper surface of the base plate through a screw. The plug pin penetrates through a hole in a working table and is inserted into the positioning base. The cushion blocks are arranged on the left edge, the middle portion and the right edge of the front side and the rear side of the upper surface of the base plate correspondingly. The positioning blocks are fixed to the upper surfaces of the cushion blocks. The upper surface of the working table is positioned by means of the positioning blocks. The locking handles are connected with the cushion block in the middle portion through pins. The locking handle and the hinge pins can rotate around the cushion block in the middle portion jointly. According to the scribing clamp for the working table surface, the structure is simple, and a workpiece can be clamped conveniently; the eccentric shaft is used for locking, clamping is reliable, the scribing precision is high, and particularly when scribing needs to be conducted on a vertical machining center, since the vertical machining center is difficult to clamp, the efficiency can be greatly increased by the adoption of the scribing clamp.

Description

technical field [0001] The invention relates to the technical field of machine tool fixture design, in particular to a work table surface engraving fixture. Background technique [0002] With the development of the machinery industry, the market has higher and higher requirements for the function and precision of machine tools, so many manufacturers of machine tools have been produced, and the workbench is often adjusted on the machine tools to adapt to different shapes and sizes. The processing requirements of parts, in order to ensure the machining accuracy of workpieces, scale lines are drawn on the workbenches of most machine tools. Ordinary fixtures used for workbench engraving have complex structures, unreliable clamping, and low accuracy and efficiency. , so it is necessary to design a jig with simple structure, reliable clamping, high marking accuracy and high efficiency for workbench marking. Contents of the invention [0003] The purpose of the present invention...
