Embodiment Construction

[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0020] see Figure 1 to Figure 3 As shown, the present invention is a lathe spindle end clamping block specially used in the knurling process of the shaft section without a center hole. One end is provided with a first placement groove 10, and the lathe spindle end clamp block 2 is symmetrically provided with four internally threaded through-holes 12 whose bottom ends in the first placement groove 10.

[0021] The assembly method of the present invention is as follows. First, one end of the lathe spindle end clamp block 2 is placed in the lathe spindle chuck 1, and one end of the processed shaft section 5 is inserted into the first placement groove 10, and then fixed with the locking screw 7. The second The size file D1 of a placement groove 10...

Abstract

The invention discloses a lathe spindle end fixture block special for a knurling process of a shaft section without a central hole. The section of the lathe spindle end fixture block is convex, one end of the lathe spindle end fixture block is placed in a lathe spindle chuck, a first containing groove is arranged at the other end of the lathe spindle end fixture block, and four internally threaded through holes with bottoms ending at the first containing groove are symmetrically arranged on the lathe spindle end fixture block. The lathe spindle end fixture block is simple in structure and convenient in use.

Description

technical field [0001] The invention relates to a mold fixing device, in particular to a lathe spindle end clamping block specially used in the knurling process of the shaft section without a center hole. Background technique [0002] In mechanical products, some transmission mechanisms need to use the shaft as a coupling-linkage light-load transmission member, or as the hand-holding part of the handle rod (operating rod). In order to increase the surface friction, the circumferential surface of the shaft should be knurled processing, so as to achieve the purpose of power transmission. [0003] It is difficult to process the circumferential surface knurling of a shaft section without a center hole at both ends of the machined shaft section or a shaft section taken from a certain long axis due to the lack of center hole positioning. [0004] When processing the knurling process on the circumferential surface of the shaft section without a center hole, the "clip-top" process ...
