Clamp splice composite set specially used for centre-hole-free shaft section knurling process

Abstract

The invention discloses a clamp block composite set specially used for a centre-hole-free shaft section knurling process. The clamp block composite set comprises a lathe main shaft end clamp block, a lathe tail bed end clamp block and multiple locking screws, and the cross section of the lathe main shaft end clamp block is of a shape like a Chinese character tu; one end of the lathe main shaft end clamp block is arranged in a lathe main shaft chuck, the other end of the lathe main shaft end clamp block is provided with a first placing groove, and the lathe main shaft end clamp block is symmetrically provided with four internal thread through holes the hole bottoms of which are ended in the first placing groove; one end of the lathe tail bed end clamp block is provided with a second placing groove, the other end of the lathe tail bed end clamp block is provided with a bearing chamber, the bearing chamber is internally provided with a bearing, and one end of a pinnacle cone of a lathe tail bed end is connected with the bearing chamber; and the lathe tail bed clamp block is symmetrically provided with the four internal thread through holes the hole bottoms of which are ended in the second placing groove, and the locking screws are arranged in the internal thread through holes. The clamp block composite set provided by the invention has the advantages of simple structure, convenience in use, and exact positioning.

Description

technical field [0001] The invention relates to a mold fixing device, in particular to a clamp block combination device specially used in the knurling process of a 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. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a clamping block combination device s...

AI Technical Summary

Problems solved by technology

[0003] It is difficult to machine due to the lack of center hole positioning for the shaft section that has no center hole at both ends of the machined shaft section or the shaft section that has been removed from a long axis for knurling on the circumferential surface
