Clamp of machine tool

Abstract

The invention discloses a clamp of a machine tool. The clamp comprises a clamp base, a first electric telescopic rod, a fixed plate, a first compressing mechanism and a second compressing mechanism, wherein the clamp base is of a cuboid structure; the first electric telescopic rod is arranged on the middle part in the clamp base; the telescopic upper end of the first electric telescopic rod is connected with the fixed plate; the upper end of the fixed plate extends out to the upper end surface of the clamp base; a second electric telescopic rod and a third electric telescopic rod are separately fixedly arranged on two sides of the upper end surface of the clamp base; the right side telescopic end of the second electric telescopic rod is fixedly connected with a first clamping plate; the left side telescopic end of the second telescopic rod is fixedly connected with a second clamping plate; and the upper part of the first clamping plate is rotatably connected with the first compressingmechanism through a first bolt. By adopting the clamp, two groups of workpieces can be clamped synchronously, and clamping is firm through the two compressing mechanisms; workpieces of various specifications and sizes can be clamped; clamping efficiency is high; and practicability is high.

Description

technical field [0001] The invention belongs to the technical field of machine tool clamping parts equipment, and in particular relates to a machine tool clamp. Background technique [0002] Machine tool fixture is a device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position for construction or inspection. In a broad sense, any process in the process, the device used to install the workpiece quickly, conveniently and safely, can be called a fixture. When processing a workpiece on a machine tool, in order to make the surface of the workpiece meet the technical requirements such as the size, geometric shape, and position accuracy with other surfaces specified in the drawing, the workpiece must be installed (positioned) and clamped (clamped) before processing. . [0003] At present, when machining parts on machine tools, it is relatively simple to clamp standard parts with fixtures, but when clamping workpieces...

AI Technical Summary

Problems solved by technology

[0003] At present, when machining parts on machine tools, it is relatively simple to clamp standard parts with fixtures, but when clamping irregularly sized workpieces, the fixtures will not be firm or unstable, causing potential safety hazards. At the same time, the current fixture height It cannot be changed. When clamping and processing parts with slightly higher or lower heights, instability will occur, and it cannot adapt to multiple sets of workpieces with specifications and sizes, which increases production costs.
