Problems solved by technology

[0003] However, the press-fitting machine usually performs press-fitting with the initially given pressure value. Due to the influence of the precision of the water pump body, shaft-connected bearings, and water seals, there will be certain tolerances in the dimensions of the water pump body, shaft-connected bearings, and water seals. If the assembly is carried out according to the traditional press-fitting method, there is a problem that the shaft-connected bearing and the water seal are too deep or too shallow to be pressed into the water pump body, making it difficult to accurately control the fit between the water pump body, shaft-connected bearing and water seal. Within a more reasonable range, it is easy to cause large differences in the performance of the output automotive mechanical water pumps and poor consistency

Abstract

The invention discloses assembling equipment for an automobile mechanical water pump, which comprises a workbench, a placing and positioning mechanism used for vertically placing a shaft connecting bearing and a water seal, a water pump body fixing seat and a pressing mechanism provided with a pressing head are sequentially arranged on the workbench from bottom to top, a through hole allowing the shaft connecting bearing and the water seal to penetrate through is formed in the water pump body fixing seat, the pressing head, the center hole of a water pump body fixedly installed on the water pump body fixing seat and the through hole are coaxially arranged from top to bottom in the vertical direction, the placing and positioning mechanism can be horizontally and movably arranged on the workbench and used for sequentially moving the shaft connecting bearing and the water seal to the position under the through hole, and the pressing mechanism is provided with a pressure sensor used for detecting the pressure value of the pressing head, a displacement sensor used for detecting the pressing stroke of the pressing head and a PLC with a preset displacement range and a preset pressure value range. The assembling equipment has the advantage that the produced automobile mechanical water pump is good in consistency.

Description

technical field [0001] The invention belongs to the technical field of assembly equipment for automobile parts, in particular to an assembly equipment for an automobile mechanical water pump. Background technique [0002] Automobile mechanical water pumps are usually composed of water pump body, shaft-connected bearing, water seal and other components. As well as the interference fit between the water seal and the water pump body, the traditional assembly method is to use a press machine for assembly, first place the water pump body on the workbench, then place the shaft-connected bearing and water seal on the workbench in turn Located on the axis of the water pump body, the shaft-connected bearings and water seals are press-fitted into the water pump body one by one by a press-fitting machine. [0003] However, the press-fitting machine usually performs press-fitting with the initially given pressure value. Due to the influence of the precision of the water pump body, shaf...
