Indexing tool

Abstract

The invention relates to the field of key groove machining, and provides an indexing tool. The indexing tool comprises a base, and the base is provided with a circular main dial and installing holes;a vernier scale is installed on the base and can slide along the circular main dial, and the circular main dial and the vernier scale are locked through a locking mechanism; and the vernier scale is provided with a machining benchmark. The indexing tool is installed on a to-be-machined workpiece and installed on machining equipment together with the to-be-machined workpiece. The indexing tool is provided with the circular main dial and the vernier scale, and therefore indexing of the to-be-machined workpiece is achieved by adjusting the position of the vernier scale on the circular main dial and always ensuring that the machining benchmark on the vernier scale is located in the movement journey direction of a tool bit of the machining equipment. The indexing tool can be suitable for indexing shaft parts and hole parts simultaneously and can be used on any equipment with an indexing tool installing station, the two-way selection requirements between the equipment and the workpiece are reduced, and the applicability of the equipment and the applicability of the workpiece are enhanced.

Description

technical field [0001] The invention relates to the field of keyway processing, in particular to an indexing tool, more specifically an indexing tool for keyway processing. Background technique [0002] The keyway is generally a structure that transmits torque for rotary parts such as shafts and holes, and is affected by the magnitude of the torque. The number of keyways on rotary parts can be divided into single key, double key, spline, etc., and the keyway forms and angles are diverse. [0003] In the prior art, the multi-angle splines of shaft parts are generally indexed by indexing heads, special equipment or special forming tools; the multi-angle splines of hole parts are generally indexed by slotting machines, related special equipment or forming tools . The existing processing techniques and indexing methods of these two types of multi-angle spline workpieces all have the problems of low applicability to equipment (that is, the workpiece can only be processed on cer...

AI Technical Summary

Problems solved by technology

The existing processing techniques and indexing methods of these two types of multi-angle spline workpieces all have the problems of low applicability to equipment (that is, the workpiece can only be processed on certain types of equipment) and high equipment costs; The applicability of the processing equipment itself to the workpiece is also low (that is, the equipment can only process a certain range of workpieces)

[0004] Due to the dual selection of workpieces and equipment, it is difficult for general companies to independently complete the indexing of keyways with various dimensions and parameters with high quality and high efficiency. The main technical difficulty causing this double restriction lies in the division of multi-angle splines. Spend
