Description

Technical Field

[0001] This utility model relates to the technical field of gear production equipment, specifically a lubricating pinion production equipment. Background Technology

[0002] Lubricating pinions are used in conjunction with lubrication pumps or distributors. By meshing with the gear being lubricated, and maintaining the meshing end of the lubricating pinion, lubricant is dissipated, allowing the lubricant to evenly cover the gear being lubricated. During the manufacturing process of the lubricating pinion, mounting holes are machined into it to facilitate connection with other components.

[0003] Chinese utility model patent application CN108500320A discloses a drilling machine for gear processing. This drilling machine includes a first motor with a threaded rod fixedly connected to its output end. A support plate is located on top of the first motor, and a second motor is located on top of the support plate. A drilling tool is fixedly connected to the output end of the second motor. A first push rod is fixedly connected to the bottom of the support plate, and a first locking block is fixedly connected to the end of the first push rod away from the support plate. The end of the drilling tool away from the second motor sequentially penetrates the outer surface of the support plate, the outer surface of the first push rod, and the outer surface of the first locking block, extending to the outside of the first locking block. A first pull ring is fixedly connected to the bottom of the support plate. A pressure box is located on one side of the first motor, and the second push rod is located inside the pressure box. This drilling machine for gear processing has the advantages of simple structure, high working efficiency, and automatic drilling of gears. However, after drilling a gear, the machine cannot promptly detect when drilling is complete. Continuing to drill may damage the drill table and reduce the drilling efficiency of the lubricated pinion. Therefore, improvements are necessary. Utility Model Content

The lifting mechanism drives the drill bit downward to drill a hole in the lubricating pinion blank. The drill bit pierces the lubricating pinion blank. As the drill bit descends, it pushes the moving rod downwards, and the positioning block on the moving rod descends with it. After the positioning block disengages from the positioning hole, the connecting plate stops rotating with the shaft, and the rotational speed of the lubricating pinion blank begins to decrease, allowing the operator to quickly know that drilling is complete. The lifting mechanism moves upwards, and the moving rod moves upwards under the action of the return spring. The positioning block re-enters the positioning hole, controlling the drive mechanism to drive the shaft to rotate in the opposite direction. The stud does not rotate under the action of the counterweight, and the connecting ring moves downwards along the stud, releasing the lubricating pinion blank and completing the lubricating pinion drilling operation. Compared with the prior art, the lubricating pinion production device of this utility model allows for notification after drilling is completed, avoiding damage to the drill table caused by the drilling mechanism and helping to improve the production efficiency of lubricating pinions.
