Embodiment Construction

[0008] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0009] Such as figure 1 As shown, the quick-change work chuck includes a power shaft 301 , a housing 302 , a bearing seat 303 , a clamping body 304 , an elastic sleeve 305 , a locking nut 306 , a retaining ring 307 , and a grinding rod 308 .

[0010] During actual work, put the grinding head rod 308 into the power shaft 301 and the elastic sleeve 305. Since the elastic sleeve is an elastic split sleeve, it cooperates with the lock nut 306 as a tapered surface. When the lock nut is turned, it will move axially, so that The elastic sleeve 305 produces clamping deformation, thereby clamping the grinding head rod. Conversely, loosen the grinding rod.

[0011] The above description is an explanation of the present invention, not a limitation of the invention. For the limited scope of the present invention, refer to the claims. The present inv...

Abstract

The invention relates to a quick-mounting working chuck, which comprises a power shaft, a casing, a bearing block, a holder, an elastic sleeve, a locknut, a retainer ring and a grinding head rod, wherein the grinding head rod is installed in the power shaft and the elastic sleeve, the elastic sleeve is an elastic open sleeve and is matched with the conical surface of the locknut, when the locknut is rotated, the elastic sleeve can be clamped and deformed to clamp the grinding head rod. The quick-mounting working chuck has compact structure and easy clamping, and can quickly clamp and replace polishing working chucks which are suitable for aluminum parts.

Description

technical field [0001] The invention relates to the field of machining equipment, in particular to a quick-change work chuck. Background technique [0002] The quick-fit work chuck is a commonly used structure on machine tool equipment and electric tools, and is used to quickly replace and fasten the head tool of the processing equipment. However, the current quick-change work chucks generally have the characteristics of large volume and complicated clamping, and are especially not suitable for grinding operations where the workpiece is aluminum. Contents of the invention [0003] Aiming at the disadvantages of the above-mentioned existing quick-change work chucks for thin-walled parts, such as large volume and inconvenient clamping, the applicant provides a quick-change work chuck with a reasonable structure, which is compact in size and convenient in clamping. [0004] The technical scheme adopted in the present invention is as follows: [0005] A quick-change work chu...
