Problems solved by technology

There are three disadvantages of press-fitting in this way: 1) Most of the water pump body is irregular in shape, and there is a biased situation. After the pump body is placed, the center of the bearing will shift; , after the pump body is put in, the small end of the bearing is offset, and the bias pressure is generated when the water seal is pressed.
3) The above press-fitting method requires at least two people to operate, which is time-consuming and labor-intensive, and the assembly efficiency is extremely low. Two people can only install 20 pieces in 8 hours a day. More importantly, the yield is low, and the yield is only 60%.
The press-fitting efficiency of the utility model is improved, and the positioning of the water seal is not accurate, and it is easy to crush the water pump and the bearing

Abstract

The invention discloses a water seal assembling device and method for an engine cooling water pump. The water seal assembling device comprises a workbench and a centering and press-fitting mechanism arranged on the workbench. The center of the workbench is provided with a water seal locating and guiding mechanism. The centering and press-fitting mechanism comprises a floating supporting mechanism connected with the workbench through a lifting mechanism, a clamp body located on the floating supporting mechanism and a press-fitting mechanism located on the upper portion of the floating supporting mechanism. The floating supporting mechanism comprises a lifting plate arranged on the workbench and a floating plate connected with the lifting plate through a rolling mechanism. By means of the assembling method, accuracy of water seal installation is high, damage to a bearing is avoided and mounting efficiency is high.

Description

technical field [0001] The invention relates to the technical field of installation equipment for an automobile water pump water seal, in particular to a water seal assembly device and an assembly method for an engine cooling water pump. Background technique [0002] Centrifugal water pumps are widely used in automobile engines, and their basic structure is composed of water pump body, bearing, water seal, impeller, pulley and other components. According to different bearing structures, it can be divided into shaft-connected structure water pumps and separate structure water pumps. Shaft-connected structure water pumps are water pumps that use shaft-connected bearings. The traditional assembly method is as follows: the water seal is installed on the water seal pressure head; the large surface of the pump body faces upward, and the water pump assembly with the bearing installed is positioned by the outer circle of the large end of the bearing and the small end surface of the...
