Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a drilling device for a universal joint fork of an automobile engine. Background Art

[0002] Universal joint forks are often used on drive shafts, usually located at the end of the transmission. Their outer circle and inner hole match the shaft at the end of the drive shaft. Their main function is to transmit torque and adjust the length and position relationship of the drive shaft.

[0003] In the process of drilling holes in the yoke, workers are often required to place the yoke to be drilled into a special fixture and then fix it before drilling. Moreover, only one yoke can be drilled at a time, which reduces the processing efficiency. Moreover, after the drilling is completed, it takes a lot of time for the workers to disassemble the drilled yoke. Moreover, the process is cumbersome and it is not convenient to drill holes in batches on the yoke, which reduces the practicality of the drilling equipment for the yoke of automobile engines.

[0004] For example, a car engine universal joint fork drilling device disclosed in Chinese patent CN210648633U can drill holes in the universal joint fork body in batches, and the fixing and disassembly processes are very simple and convenient, which greatly improves the drilling efficiency of the universal joint fork body. By setting the height of the bottom end of the drilling device body to be higher than the height of the extrusion plate, when the multi-stage hydraulic cylinder extends and drives the drilling device body and the extrusion plate to move downward, the two extrusion plates can first contact and press the upper universal joint fork body before the bottom end of the drilling device body can contact the universal joint fork body. The function of the first spring is that when the extrusion plate has contacted the universal joint fork body, the downward movement of the drilling device body can compress the first spring, so that the extrusion plate presses the universal joint fork body more tightly, thereby limiting the universal joint fork body, and the telescopic rod can make this process more stable.

[0005] However, when the device is drilling a hole in the universal joint fork, metal powder will be generated. The metal powder will be scattered in the air and inhaled by the workers, causing damage to the workers' bodies.

[0006] For this reason we urgently need to provide a kind of drilling equipment of automobile engine universal joint fork. Utility Model Content
