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 201 , a clamping sleeve 202 , a clamping body 203 , a bevel 204 , a locking nut 205 , and a grinding rod 206 .

[0010] During actual work, the keyway is opened on the grinding head rod 206, the clamping body 203 and the grinding head rod are put into the power shaft 201 together, and the locking nut 205 is rotated, because the clamping sleeve 202 and the clamping body 203 are in an arc Cooperating, the axial movement of the locking nut 205 causes a slight swing of the clamping body 203 , thereby clamping the grinding head rod 206 .

[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 invention can be modified in any fo...

Abstract

The invention relates to a quick-change working chuck, which comprises a power shaft, a clamping sleeve, a clamping body, an inclined surface, a locking nut and a grinding head rod, wherein a key groove is formed on the grinding head rod and is arranged in the power shaft together with the clamping body; the clamping sleeve is in arc fit with the clamping body; and an axial movement of the locking nut slightly swings the clamping body; therefore, the grinding head rod is clamped. The quick-change working chuck is compact in structure and convenient to clamp, can rapidly clamp and replace a grinding head, and is applied to 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...
