Portable oil seal press-fitting device

Abstract

The invention discloses a portable oil seal press-fitting device. The portable oil seal press-fitting device is characterized by comprising a connecting plate (3), a positioning mechanism, a locking mechanism, a press-fitting mechanism and a driving power mechanism; the positioning mechanism is detachably connected in the locking mechanism and located below a pressure head push rod (7) in the press-fitting mechanism; the lower end of the positioning mechanism is connected with a transmission oil pump assembly (30) to be press-fitted in a matched mode; the locking mechanism and the press-fitting mechanism are both connected with the driving power mechanism and controlled and driven by the driving power mechanism independently; the driving power mechanism is connected to the upper portion of the connecting plate (3); and the press-fitting mechanism and the locking mechanism are connected to the lower portion of the connecting plate (3). By the adoption of the structure, the oil seal press-fitting device is portable; and in addition, the positioning mechanism is connected with an oil seal installation hole of the transmission oil pump assembly in a matched mode, so that the press-fitting device and the transmission oil pump assembly are combined, and the press-fitting coaxiality of an oil seal is guaranteed.

Description

technical field [0001] The invention relates to the technical field of assembly tooling, in particular to a portable oil seal press-fitting device used on a gearbox oil pump assembly. Background technique [0002] The oil seal on the automobile transmission oil pump assembly is a key part to ensure the sealing performance. The traditional oil seal assembly adopts the press-fitting method, that is to say, the transmission oil pump assembly is placed on the press-fitting machine, and then the oil seal is sealed by the press-fitting machine. Press fit one by one to the oil pump assembly. For example, on the website of the State Intellectual Property Office, the publication number is CN104191207A "support wheel floating oil seal pressing machine" patent, which includes a workbench, frame, cylinder, fixed pressure head and movable pressure head, and the workbench is placed inside the frame The lower part of the cylinder, the cylinder body is fixed on one side of the frame, and t...

AI Technical Summary

Problems solved by technology

[0003] 1) It cannot be moved and carried, and when the oil seal has been installed in the transmission oil pump, it is necessary to replace the oil seal and the transmission oil pump cannot be moved, this kind of press machine is obviously not applicable

[0004] 2) In addition, it needs a frame to support the entire press-fitting device. In other words, the supporting wheels have to be moved to the workbench for press-fitting of the oil seal. Therefore, it is not difficult to see that the support The heavy wheel and the pressure head are separated, which will affect the position of the oil seal and the oil seal hole on the supporting wheel, resulting in poor coaxiality of its press fit
