Abstract

This utility model discloses a machine tool clamping assembly, including a convenient rotating mechanism, a clamping mechanism, and a fixing mechanism. The convenient rotating mechanism includes a mounting plate with a mounting groove inside. A fixing rod is fixedly connected inside the mounting groove. A motor is fixedly mounted at one end of the fixing rod, and a rotating shaft is fixedly connected to the output end of the motor. A first electric push rod is fixedly mounted at one end of the rotating shaft. Through the convenient rotating mechanism, activating the first electric push rod extends it, pushing a limiting disc to slide within the limiting groove of the mounting frame until the locking block disengages from the groove. This allows the mounting frame to be manually rotated. When micro-rotation is not required, the mounting frame can be rotated to align the locking block with the groove. The first electric push rod then drives the limiting disc back to its original position, causing the locking block to re-engage in the groove, thereby fixing the mounting frame and the angle of the entire clamping assembly.

Description

Machine tool clamping assembly

Machine tools refer to machines for manufacturing machines, also known as machine tools or machine tools, which are mainly used for machining surfaces of revolution bodies, such as cylindrical surfaces, conical surfaces, threads, etc. It is one of the most widely used machine tools, for example, in a machine manufacturing factory, the machine tool can be used for machining various shaft parts, a blank (such as cylindrical steel) is clamped on a main shaft of the machine tool, a shaft meeting the size requirement can be turned by adjusting the position and the feeding speed of a cutter, and the diameter, the length, the surface finish and the like of the shaft can be controlled by the machining of the machine tool.

In the actual operation of a machine tool, the clamping assembly plays a key role in fixing the object to be machined. Most of the existing clamping assemblies rely on mechanical control to realize rotation, and the traditional rotation mode has obvious limitations and lacks a convenient manual control and adjustment function.
