Clamping device of numerical control machine tool

Abstract

The invention discloses a clamping device of a numerical control machine tool, and belongs to the technical field of numerical control machine tools. The clamping device comprises a workbench and a supporting seat, the workbench is placed on the ground, the supporting seat is fixedly arranged on the workbench, clamping equipment is further arranged on the supporting seat, a containing groove is formed in the supporting seat, and the clamping device is in running fit with the supporting seat; and the clamping equipment comprises a driving assembly, a matching assembly, a clamping assembly and two fixing assemblies, the driving assembly is arranged in the containing groove in the supporting seat, the matching assembly is arranged on the driving assembly, the clamping assembly is arranged on the matching assembly, the fixing assemblies are arranged on the matching assembly, the two fixing assemblies are symmetrically arranged on a driving frame, and a machining device is further arranged on the workbench. A machined part is fixed through the clamping equipment, and the situation that when the machined part is machined, due to rapid rotation of a driving motor, the machined part is loosened during rotation, the machining precision of the machined part is affected, and the product quality of the machined part is poor is prevented.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a clamping device for numerical control machine tools. Background technique [0002] The clamping device, of course, refers to the device that the CNC machine tool clamps the parts when processing the parts, which is convenient for the processing of the CNC machine tool. The commonly used clamping devices include (spiral) clamping devices, wedge clamping devices and eccentric clamping devices. , the clamping should not destroy the positioning of the workpiece, or produce excessive clamping deformation, but also have sufficient clamping force to prevent the workpiece from vibrating during processing, sufficient clamping stroke, fast clamping action, and easy operation , safe and labor-saving, the manual clamping mechanism must have reliable self-locking properties, and the motorized clamping device must take into account the clamping self-locking and the st...

Problems solved by technology

[0005] An embodiment of the present invention provides a clamping device for a numerically controlled machine tool to solve the problem that the workpiece may loosen during rotation due to the rapid rotation of the drive motor, which affects the machining accuracy of the workpiece and may lead to product failure of the workpiece. The quality is poor, and the inner wall of the processed part may be rusted or other problems caused by long-term placement, which may cause the inner wall of the processed part to be uneven, so that the processed part may shake when it is fixed, which affects the quality of the processed product.
