Problems solved by technology

However, the current press-fitting tool is easy to damage the oil seal during the press-fitting process. The process of the oil seal being pressed into the rear end cover of the crankshaft is not pressed in as a whole, but unilaterally pressed in, so it is difficult to ensure the tightness of the oil seal. It is difficult to ensure the position of the oil seal in the rear end cover of the crankshaft after being press-fitted

Embodiment Construction

[0011] Referring to FIG. 1 , the press-fit tool is composed of a support base 1 , a press-fit sleeve 3 , a positioning pin 5 and a guide rod 6 . A positioning pin 5 is knocked into the support seat 1 through interference fit, and a guide rod 6 is arranged on the support seat 1 corresponding to the center position of the rear end cover 2 of the crankshaft. The guide rod 6 and the center hole 31 of the shank of the press fitting sleeve Clearance fit, referring to Fig. 2 and Fig. 3, the bottom end of the press-fit sleeve 1 is in interference fit with the crankshaft rear oil seal 4, and a positioning slope 32 is provided at the bottom end.

[0012] See Figure 1 for the oil seal after press-fitting the crankshaft. First, fix the support base 1 with positioning pins and guide rods on the workbench with four M6 bolts, then place the crankshaft rear end cover 2 on the support base 1, and pass the support base The positioning pin 5 on 1 is positioned with the clearance of the positioni...

Abstract

A press tool for installing the back oil seal for the crankshaft of engine is composed of a supporter, a locating pin inserted in the supporter for locating the back end cover of crankshaft, a guide rod on said supporter, relative to the central position of back end cover and matched with the central hole of press sleeve, and a press sleeve for guiding the back oil seal and transferring pressure to it.

Description

technical field [0001] The invention belongs to the technical field of engine assembly, and in particular relates to a tool for installing an engine crankshaft oil seal. Background technique [0002] When the engine rear oil seal is assembled, it needs a relatively large pressure to press into the crankshaft rear end cover. During the assembly process, it is required not to damage the oil seal, and the position where the oil seal is pressed into the crankshaft rear end cover must meet the technical requirements, otherwise it will cause engine leakage. Oil. However, the current press-fitting tool is easy to damage the oil seal during the press-fitting process. The process of the oil seal being pressed into the rear end cover of the crankshaft is not pressed in as a whole, but unilaterally pressed in, so it is difficult to ensure the tightness of the oil seal. It is difficult to ensure the position of the oil seal in the rear cover of the crankshaft after being pressed. Con...
