Drilling device of speed changing drum

Abstract

The invention provides a drilling device of a speed changing drum. The drilling device comprises a bottom plate and an upper mold plate which are parallel to each other; a driving component for driving the bottom plate and the upper mold plate to relatively move is arranged between the bottom plate and the upper mold plate; the bottom plate is provided with a first drilling mold sleeve, and the upper mold plate is provided with a second drilling mold sleeve; the first drilling mold sleeve and the second drilling mold sleeve are provided with coaxial and opposite centers; and the first drilling mold sleeve and the second drilling mold sleeve are each provided with a drilling sleeve and a drill bit installed in the drilling sleeve. According to the drilling device of the speed changing drum, the first drilling mold sleeve and the second drilling mold sleeve are arranged on the bottom plate and the upper mold base which are parallel to each other, the distance between the bottom plate and the upper mold base can be changed, the coaxial and opposite centers are arranged on the two drilling mold sleeves, and hole drilling is carried out through the drilling bits on the two drilling mold sleeves after a speed changing drum prefabricated member is clamped through the centers; hole drilling at the two end faces is carried out at the same time, and other hole drilling operation is not needed; and the hole drilling positioning accuracy is improved, and the corresponding machining rate is improved.

Description

technical field [0001] The invention relates to the technical field of motorcycle parts processing, in particular to a gear shift drum drilling device. Background technique [0002] The transmission drum is a key part of the transmission mechanism in the motorcycle engine, and its machining accuracy directly affects the performance of the motorcycle's gear shifting and transmission. During the processing of the transmission drum, the axial ends of the drum need to be drilled at different positions. Existing drillers use traditional drilling machines, which can only process one hole on the end face at a time and need to manually replace and position the workpiece. The labor intensity is very high, and it is prone to problems such as drilling positions that do not meet the requirements and missing drilling. Problems, resulting in a low production pass rate of the transmission drum; how to improve the machining position accuracy of the drilling at both ends of the transmission...
