Abstract

The invention relates to a clamping workpiece on a working table for lathes and other machining equipment, in particular to a table clamp, and solves the problems that the conventional clamping workpiece has limited use range or a special clamp cannot be repeatedly used, the machining operation efficiency is low, the machining precision is hard to guarantee, and the like. The table clamp consistsof a table panel and a pressing device on the table panel, wherein the pressing device consists of a height adjustable supporting piece, a pressing block which is supported on the supporting piece, apressing lever and a supporting rod; the contact surface of the pressing block and the supporting piece is a curved surface and a pressing handle is arranged on the pressing block; one end of the pressing lever is hinged with the pressing block, and a rectangular gap is formed at the other end of the pressing lever; one end of the supporting rod is made into an inverted T-shape which is matched with an inverted T-shaped groove on the table panel; and symmetrical grooves are formed on the end faces of two sides of the supporting rod. The table clamp has wide application range; the volume rangeof workpieces clamped by the clamp is doubled; and the clamping positions of irregular workpieces are flexible. The table clamp has the characteristics of simple and reliable structure, convenient and fast operation and repeated use.

Description

technical field [0001] The invention relates to a clamping workpiece on the working table of machining equipment such as a milling machine, a drilling machine, a planer, and a lathe, in particular to a table clamp. Background technique [0002] Milling machines, drilling machines, planers, lathes and other machining equipment with worktables. The commonly used clamping workpieces are desktop vises, dividing heads or specially designed special fixtures fixed on the worktables. The degree head is suitable for occasions where the shape of the workpiece to be processed is relatively square and the volume is small. Usually, special-shaped workpieces with large volume need to be designed and manufactured, which not only increases the processing cost, prolongs the processing cycle, and increases the working intensity, but also usually It is relatively simple, rough, and cannot be reused. At the same time, this special fixture has poor adjustability when pressing the workpiece, and ...
