A rotary-guided push-type pressure oil seal tooling

Abstract

The invention discloses a rotary steering push type oil seal pressing tooling and belongs to the technical field of toolings. The tooling comprises a pilot sleeve, wherein an internal threaded section is arranged at one end of the pilot sleeve; an oil sealing groove matched with an oil seal is formed in the other end of the pilot sleeve; a pressing plate groove communicated with the inner threaded section and the oil sealing groove is arranged between the inner threaded section and the oil sealing groove; a pressing plate is arranged in the pressing plate groove; the diameter of the pressing plate groove is not larger than that of the oil sealing groove; a threaded rod is connected with the inner threaded section; pin holes are formed in the pressing plate; pilot pins in clearance fit with the pin holes are arranged in the pin holes; the pressing plate is connected with the pilot sleeve through the pilot pins. According to the tooling provided by the invention, the threaded rod rotates in the pilot sleeve and is propped into the pressing plate, so that the oil seal is press-fitted in place through the pressing plate; moreover, the application of force is more uniform and controllable, and the accuracy and yield of the press-fitting are improved.

Description

technical field [0001] The invention relates to the field of tooling technology, in particular to a rotary guide propulsion type pressure oil seal tooling. Background technique [0002] At present, manual pressure oil seals usually use stepped shafts, and the oil seals are pressed on the stepped shafts by using the steps of the stepped shafts. During the pressing process, the pressure exerted by humans is used to complete the assembly of the oil seals, but it is difficult to control during the pressing process. , it is prone to artificially applied uneven strength and deflection during press-fitting, resulting in the press-fitted oil seal not meeting the requirements, and the pass rate of press-fitting is low and unstable. Contents of the invention [0003] The purpose of the present invention is to provide a rotary-guided push-type oil seal tooling to solve the problem of uneven strength and deflection during press-fitting caused by relying on manual pressure when the exi...
