Description

Technical Field

[0001] The utility model relates to the field of gear shaft drilling, in particular to a gear shaft drilling positioning device. Background Art

[0002] A gear shaft is a mechanical element that mounts gears directly on a shaft, combining rotation, torque and bending moment. The main functions of a gear shaft include supporting gears, transmitting power, balancing torque and keeping gears in a fixed position. In gear transmission, the gear shaft transmits power through the mutual meshing of gears, transmitting the power of the prime mover to the corresponding mechanical parts to realize the operation of mechanical equipment. The design of the gear shaft usually requires consideration of its strength, stiffness, size and shape to ensure the normal operation of the gear and reduce stress concentration.

[0003] When processing the end of the gear shaft, it is usually necessary to use a positioning fixture to position it. When most gear shafts are centered, the mold is usually put on the gear shaft and positioned through the through holes on the mold. However, different types of molds are required for gear shafts of different specifications and sizes, which increases the processing cost. When the molds are connected, if molds of inconsistent specifications are used, they need to be disassembled and replaced, which is time-consuming and labor-intensive. In addition, debris will be generated during processing, which is more complicated to clean. Utility Model Content
