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 compression mechanism and a second compression mechanism, wherein the clamp base is of a cuboid structure; the first electric telescopic rod is mounted in the middle of the clamp base; the upper telescopic end of the first electric telescopic rod is connectedto a fixed plate; the upper end of the fixed plate stretches out of the upper end surface of the clamp base; a second electric telescopic rod and a third electric telescopic rod are fixedly mounted on two sides of the upper end surface of the clamp base, separately; a first clamping plate is fixedly connected to the right telescopic rod of the second electric telescopic rod; a second clamping plate is fixedly connected to the left telescopic end of the second electric telescopic rod; and the first compression mechanism is rotatably connected to the upper side of the first clamp through a first bolt. The clamp of the machine tool can clamp two workpieces at one time, is firm to clamp through two compression mechanisms, can clamp workpieces of various specifications and dimensions, and is high in clamping efficiency and high in practicality.

Description

technical field [0001] The invention belongs to the technical field of clamping parts equipment for machine tools, and in particular relates to a clamp for machine tools. 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 ...

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.
