Abstract

The invention discloses a gear drilling tool which comprises an angle location mechanism and a base. The angle location mechanism comprises a locating turnplate capable of coaxially fixing a gear, a locating shaft coaxially arranged on the locating turnplate and locating ejector pins arranged on the base and used for fixing the position of the locating turnplate. One end of the locating shaft is inserted in the base and is in running fit with the base, a plurality of through holes formed in the axial direction of the locating turnplate are evenly formed in the circumferential direction of the locating turnplate, and the locating ejector pins are in sliding fit with the base in the axial direction of the locating turnplate to be used for being inserted in the through holes to fix the circumferential position of the locating turnplate. The gear drilling tool achieves rapid location through the matching of the through holes in the locating turnplate and the locating ejector pins, improves drilling efficiency and guarantees drilling precision.

Description

technical field [0001] The invention relates to a gear processing device, in particular to a gear drilling tool which can improve the processing efficiency of gear drilling. Background technique [0002] In the prior art, when drilling holes between the teeth of a transmission gear, after each drilling, the gear needs to be rotated by human eyes for positioning, and then the next drilling is performed. Drilling in this way not only has low drilling efficiency, but also easily counts the wrong number of teeth and causes the gear to be scrapped. [0003] In view of the above shortcomings, the inventors have designed a gear drilling tool to solve the above problems. SUMMARY OF THE INVENTION [0004] In view of this, the purpose of the present invention is to provide a gear drilling tool, which has the advantages of high drilling efficiency and accurate gear positioning when using the tool to drill the gear. [0005] The present invention solves the above-mentioned problems ...
