Problems solved by technology

The above press-fitting method has the following problems: at least two people are required to operate, the operation is time-consuming and laborious, and the assembly efficiency is extremely low. Two people can only install 18 pieces in 8 hours a day. More importantly, the yield rate is low, and the yield rate is only 70%.
The invention ensures that the shaft-connected bearing is free from force during press-fitting, but the operation is complicated, the efficiency of press-fitting the bearing is low, and the yield is low

Abstract

The invention discloses an assembling device and method for a shaft connection bearing of an engine cooling water pump. The assembling device comprises a workbench which is provided with a fixture body. A pressing mechanism is arranged on the fixture body. The workbench is provided with a bearing righting guiding and positioning mechanism. The bearing righting guiding and positioning mechanism comprises a guiding rod arranged inside the workbench, and the guiding rod and a telescopic rod of the pressing mechanism are coaxial. The guiding rod is in elastic connection with the workbench. A guiding head matched with a shaft of the shaft connection bearing is arranged at the upper end of the guiding rod. According to the assembling method, the precision for installing the bearing is high, and the bearing cannot be damaged, so that the installing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of installation equipment for automobile water pump bearings, in particular to an assembly device and an assembly method for shaft-connected bearings of an engine cooling water pump. Background technique [0002] The key to the assembly of shaft-connected bearings is that during the assembly process, the bearing rolling elements cannot bear the pressure fitting force, the bearing rolling elements cannot bear the axial pressure, and the irregular center of gravity of the pump body is easy to shift. Another key point is that the pump body and the bearing inner core ( For the separation type water pump (it is the pump shaft) there should be no relative displacement during the press-fitting process, that is, the dead pump body and the inner core of the bearing must be fixed. The existing press-fitting method is to adopt manual press-fitting, put the pump body on the workbench, one hand supports the pump body to ...
