Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a tool chuck for numerical control machine tools that is easy to use. Background Art

[0002] CNC machine tool is the abbreviation of digitally controlled machine tool, which is an automated machine tool equipped with a program control system. The tool chuck is a tool for fixing the tool, which is usually used in CNC machine tool processing to ensure the stability and accuracy of the tool.

[0003] For example, the application number is 202322003176.X, which is a CNC machine tool tool chuck. The rubber pad increases the friction on the tool handle, so that the tool handle is firmly clamped in the chuck body to prevent shaking, thereby reducing the wear on the tool handle; through the reset action of the first spring and the second spring, the fixed clamping block is clamped into the fixed clamping slot, thereby achieving the limit, making it easy to disassemble without the need to disassemble the entire chuck body, thus facilitating maintenance and reducing maintenance costs.

[0004] It has the following disadvantages:

[0005] 1. Due to the elasticity of the rubber pad, the tool handle has an outward centrifugal force when it rotates. The rubber pad is easily deformed under the force, which will cause the tool handle to shake during the rotation process. The shaking of the tool handle will affect the accuracy of the workpiece processing;

[0006] 2. Since the first spring and the second spring are exposed outside the chuck housing, when the chuck body is rotating at high speed, the first spring and the second spring exposed outside the chuck housing will increase the wind resistance of the chuck housing. The increase in wind resistance will increase the electrical energy required for the rotation of the chuck housing.

[0007] Therefore, we propose an easy-to-use CNC machine tool tool chuck to solve the above problems. Utility Model Content

[0035] The clamping assembly can be provided to firmly clamp the CNC machine tool tool body 3 inserted into the insertion port 2, thereby preventing the CNC machine tool tool body 3 in the insertion port 2 from shaking during rotation, thereby affecting the accuracy of workpiece processing.

[0036] A limit plate 14 is provided at the bottom inner end of the insertion port 2. Four limit plates 14 are provided and arranged in a rectangular shape.
