Detachable type Z-direction cutter assembly on machine tool

Abstract

The invention provides a detachable type Z-direction cutter assembly on a machine tool and belongs to the technical field of machine tool equipment. By means of the detachable type Z-direction cutterassembly on the machine tool, the technical problem that the Z-direction cutter assembly on an existing machine tool is high in the cost and inconvenient to use is solved. The Z-direction cutter assembly comprises a base. Fixing block assemblies are fixedly arranged on one side of the base. A rotatable screw is arranged on the other side of the base. A servo motor by which the screw can be drivento rotate is fixedly arranged at one end of the base. A sliding base is in threaded connection with the screw. A cutter fixing sleeve and a driving motor by which the cutter fixing sleeve is driven torotate are arranged on the sliding base. A synchronizing wheel is further arranged on the output shaft of the driving motor. A cutter is fixed to an end of the cutter fixing sleeve through a cutter fixing lock. The axis direction of the screw is consistent with the axis direction of the cutter fixing sleeve. By means of the detachable type Z-direction cutter assembly on the machine tool, existingmachine tool equipment can be conveniently reformed; multiple Z-direction cutter assemblies can also be used simultaneously; the Z-direction cutter assembly is relatively flexible, convenient to assemble and high in universality; and the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of machine tools and relates to a tool assembly on a machine tool, in particular to a detachable Z-direction tool assembly on a machine tool. Background technique [0002] Machine tools are equipment used to process and manufacture mechanical parts. With the improvement of production technology, CNC machine tools are more and more widely used. CNC machine tools are usually composed of control systems, servo systems, detection systems, and mechanical transmission systems. The control system is used for the calculation, management and control of the CNC machine tool. Data is obtained through the input medium, and the data is interpreted and calculated and has an effect on the machine tool; the servo system drives the machine tool according to the instructions of the control system, so that the tools and parts execute the CNC code regulations. The movement of the machine tool; the detection system is used to de...

AI Technical Summary

Problems solved by technology

[0004] The machine tools in the above patent documents are equipped with double Z-axis and double-spindle structures. After assembly and fixation, a compound tool assembly structure is formed. The overall cost is relatively high, and the Z-axis structure cannot be reduced or increased according to needs, and the use is not flexible enough.

[0005] In addition, the Z-direction tool assembly in the prior art is mainly driven by a synchronous wheel synchronous belt and can only realize a single drilling function. Poor, no pollution, less noise advantages, but synchronous belt transmission also has its fatal disadvantages: the belt is easy to twist, deform, scratch, poor precision, not resistant to oil, small torque, small machine rigidity, easy to break the belt, etc.

In addition, due to the special requirements of its use environment, this type of Z-axis assembly is only suitable for specific machine tools, and cannot be comprehensively applied to the precision transformation of most machine tools
