Description

Technical Field

[0001] The utility model relates to the technical field of axle braking, in particular to a positioning tooling for press-fitting an oil seal cover on an axle head. Background Art

[0002] In the axle braking industry, the use of an axle head and an oil seal cover is indispensable. The oil seal cover needs to be press-fitted onto the axle head with interference fit. It is required that the oil passage side holes on the oil seal cover be aligned with the oil passage side holes on the axle head. However, in the traditional press-fitting process, due to the absence of a positioning device, it is impossible to ensure the alignment of the oil passage side holes on the axle head and the oil seal cover. Moreover, after press-fitting misalignment occurs, it will cause the product to be scrapped, greatly affecting the production efficiency and causing waste of raw materials. Summary of the Utility Model

[0003] To solve the above technical problems, the utility model provides a positioning tooling for press-fitting an oil seal cover on an axle head, which can improve the processing efficiency.

[0004] A positioning tooling for press-fitting an oil seal cover on an axle head of the utility model includes a bottom plate and a support column. The support column is arranged at the top end of the bottom plate and is tubular. It also includes an oil seal cover positioning component and an axle head positioning component, and the oil seal cover positioning component and the axle head positioning component are respectively arranged at the top end of the support column. When in use, place the oil seal cover on the oil seal cover positioning component, then insert the axle head upside down into the oil seal cover and position it through the axle head positioning component, and then operate the press-fitting device, so that the axle head and the oil seal cover are in interference fit while the oil passage side holes on the axle head coincide with the oil passage side holes on the oil seal cover, improving the processing efficiency and reducing material waste.

[0005] Preferably, the oil seal cover positioning component includes a positioning sleeve and a ball plunger bolt. The positioning sleeve is arranged at the top end of the support column, and the ball plunger bolt is arranged on the support column. The moving end of the ball plunger bolt extends to the inner side of the positioning sleeve. Place the oil seal cover into the positioning sleeve while the ball plunger bolt clamps the oil passage side holes on the oil seal cover, thereby completing the positioning of the oil seal cover and ensuring the direction of the oil passage side holes on the oil seal cover.

[0006] Preferably, the axle head positioning component includes a side positioning plate and an axle head positioning pin. The support column is arranged on the support column, and the axle head positioning pin is slidably arranged on the side positioning plate. Insert the axle head upside down into the oil seal cover, insert the axle head positioning pin on the side positioning plate into the oil passage side holes on the axle head, thereby ensuring that the directions of the oil passage side holes on the axle head and the oil seal cover are the same. Then move the axle head positioning pin away from the oil passage side holes on the axle head, and then start the press-fitting device, so that the axle head keeps moving vertically downward and does not rotate. When the axle head and the oil seal cover are in interference fit, the oil passage side holes on the axle head coincide with the oil passage side holes on the oil seal cover, improving the processing efficiency.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows: during use, place the oil seal cover on the oil seal cover positioning component, then insert the shaft head upside down into the oil seal cover and position it through the shaft head positioning component, and then operate the press-fitting equipment, so that the shaft head and the oil seal cover are in interference fit and the oil passage side holes of the shaft head and the oil seal cover coincide, improving the processing efficiency and reducing material waste.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] For the convenience of understanding the utility model, the utility model will be described more comprehensively below with reference to the relevant drawings. The utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive. Embodiment

[0013] As Figures 1 to 3 shown, a shaft head press-fitting oil seal cover positioning tooling of the utility model includes a bottom plate 8 and a support column 7. The support column 7 is arranged at the top end of the bottom plate 8. The support column 7 is tubular. The tooling further includes an oil seal cover positioning component and a shaft head positioning component. The oil seal cover positioning component and the shaft head positioning component are respectively arranged at the top end of the support column 7;

[0014] The oil seal cover positioning component includes a positioning sleeve 5 and a ball plunger bolt 6. The positioning sleeve 5 is arranged at the top end of the support column 7, and the ball plunger bolt 6 is arranged on the support column 7. The moving end of the ball plunger bolt 6 extends to the inner side of the positioning sleeve 5;

[0015] The shaft head positioning component includes a side positioning plate 3 and a shaft head positioning pin 4. The support column 7 is arranged on the support column 7, and the shaft head positioning pin 4 is slidably arranged on the side positioning plate 3.

[0016] In this embodiment, the oil seal cover 2 is placed into the positioning sleeve 5, and at the same time, the ball plunger bolt 6 is used to clamp the oil seal cover oil passage side hole 10 on the oil seal cover 2, so as to complete the positioning of the oil seal cover 2. The shaft head 1 is inserted upside down into the oil seal cover 2, and the shaft head positioning pin 4 on the side positioning plate 3 is inserted into the shaft head oil passage side hole 9 on the shaft head 1, so as to ensure that the directions of the shaft head oil passage side hole 9 and the oil seal cover oil passage side hole 10 are the same. Then, the shaft head positioning pin 4 is moved away from the shaft head oil passage side hole 9. After that, the pressing equipment is started, so that the shaft head 1 moves vertically downward and does not rotate. When the shaft head 1 and the oil seal cover 2 are in interference fit, the shaft head oil passage side hole 9 and the oil seal cover oil passage side hole 10 are aligned and coincide.
