Indexing mechanism

Abstract

The invention discloses an indexing mechanism. A guide sleeve is arranged on a vertical plate; the back part of a rotating shaft is supported in the guide sleeve through two bearings ; an indexing disc is fixedly arranged on the front part of the rotating shaft in a sleeving manner; three-jaw chuck mounting holes are uniformly distributed in the indexing disc along the circumferential direction; the outer circle surface of the indexing disc is provided with four indexing pits along the circumferential direction; a central angle between the first indexing pit and the second indexing pit is 45 degrees; a central angle between the first indexing pit and the third indexing pit and a central angle between the third indexing pit and the fourth indexing pit are 135 degrees; the back end of a connecting plate is perpendicularly fixed with the right end face of the vertical plate; a bolt spring locking pin with threads is arranged in a mounting hole in the front end part of the connecting plate; a steel ball of the bolt spring locking pin with the threads can be clamped in the indexing pits in the indexing disc. According to the indexing mechanism, a rotation angle can be known when the steel ball of the bolt spring locking pin with the threads is clamped in two different indexing pits successively, the rotation angle is an indexing angle of a workpiece, the whole indexing process is clear, simple and convenient, errors occur difficultly, and the indexing efficiency and accuracy are high.

Description

Technical field [0001] The invention belongs to the field of indexing, and particularly relates to an indexing mechanism. Background technique [0002] Indexing is an important task before processing gears. At present, indexing is generally performed by an indexing head. The indexing head is inconvenient to operate, easy to make mistakes, and low indexing efficiency. Therefore, it is urgent to solve this problem. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide an indexing mechanism that is convenient to operate and not easy to make mistakes. [0004] The technical scheme of the present invention is as follows: an indexing mechanism, which is characterized in that it comprises a horizontal base plate (1), a rotating shaft (5) and a connecting plate (8), wherein a vertical base plate (1) is fixedly provided at the front end of the top surface A guide sleeve (3) is installed in the mounting hole of the vertical plate (2), and...
