Description

Technical Field

[0001] The utility model relates to the technical field of oil seal pressing, in particular to an oil seal pressing device. Background Technique

[0002] An oil seal is a mechanical component used to seal grease. It isolates the components that need to be lubricated in the transmission components from the external components, thereby avoiding the leakage of lubricating oil. It is widely used in automotive components, such as power take-off oil seals, transmission first shaft cover oil seals, rear bearing cover oil seals, etc. The current batch pressing method for oil seals is a special press, and the base below and the press head above are both special tooling;

[0003] For example, in the utility model patent with the publication number CN207746658U, an oil seal pressing device is disclosed. The purpose is to keep the parts and the oil seal press head concentric by using a positioning and guiding device, which can ensure that the oil seal and the parts are concentric and the oil seal does not skew during the pressing process, avoiding the problem of the oil seal being trimmed during the pressing process due to the skew of the oil seal;

[0004] However, although the existing pressing device meets the installation quality problem, it is necessary to install the next part and oil seal after the pressing is completed, with low efficiency and unable to efficiently install oil seals for batch parts. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides an oil seal pressing device to solve the problems raised in the above background technique.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: an oil seal pressing device, including a press, a press head, and a base. The base is fixedly installed on the working table of the press. A rotating shaft is rotatably installed on the base. Two die seats are fixedly installed on both sides of the bottom of the rotating shaft through a first connecting rod. Two sleeves are installed on both sides above the rotating shaft by using a second connecting rod. The two sleeves are vertically corresponding to the two die seats. A lifting rod is slidably installed in the sleeve, and a die head is fixedly installed at the bottom of the lifting rod.

[0007] Preferably, a baffle is fixedly installed at the upper end of the lifting rod, and a spring is installed between the baffle and the sleeve on the outer side of the lifting rod.

[0008] Preferably, mounting brackets are fixedly arranged on both sides above the rotating shaft. An opening is formed in the mounting bracket, and the second connecting rod is hinged on one side of the opening close to the rotating shaft.

[0009] Preferably, the included angle between the two die seats is 180 degrees.

[0010] Beneficial Effects

[0011] The utility model provides an oil seal pressing device, which has the following beneficial effects: by respectively arranging a die head and a die base on both sides of a rotating shaft, an oil seal and parts can be installed on the die head and die base on the other side while pressing, improving the production efficiency. At the same time, it avoids the need for workers to put their hands under the pressing head during crimping, improving the safety of the workers. By pulling the die base, the rotating shaft can be rotated, facilitating the position adjustment. By pulling the sleeve upward, the die head can face the worker, facilitating the installation of the oil seal on the die head. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0016] Please refer to Figure 1-2 , the present utility model provides a technical solution: an oil seal pressing device, including a press 1, a pressing head 2, and a base 3. The base 3 is fixedly installed on the working table of the press 1. A rotating shaft 4 is rotatably installed on the base 3. Two die bases 6 are fixedly installed on both sides of the bottom of the rotating shaft 4 through a first connecting rod 5. The die bases 6 are used to place parts. Two sleeves 7 are installed on both sides above the rotating shaft 4 through a second connecting rod 14. The two sleeves 7 are vertically corresponding to the two die bases 6. A lifting rod 8 is slidably installed in the sleeve 7. The bottom of the lifting rod 8 is fixedly installed with a die head 9. The die head 9 is provided with a stepped groove. The oil seal can be sleeved on the stepped groove to be installed on the die head 9. By pressing the lifting rod 8 down with the pressing head 2, the die head 9 can be inserted into the part, thereby installing the oil seal in the part.
