Static hydraulic pump motor oil seal packaging technology apparatus

Abstract

The name of the invention is hydrostatic pump motor oil seal assembly tool, which relates to an oil seal assembly tool. It mainly solves the problem that when the oil seal is assembled, the hammer is used to knock back and forth along the edge of the oil seal back and forth, the force is uneven, and the oil seal is easily cracked by directly hitting the oil seal. In the present invention, an oil seal upper end cover positioning shaft and a central positioning shaft are fixed perpendicular to the base on the upper end surface of the base, a handle support plate is fixed perpendicular to the base on the side of the end surface of the base, and a handle support plate is fixed on the end of the handle support plate. The handle arranged parallel to the base, and the oil seal fixing seat are connected to the central positioning shaft through clearance fit. When the present invention is in use, the oil seal fixing seat is positioned through the central positioning shaft on the base, and the end cover is positioned through the two end cap positioning shafts and the central positioning shaft, so that the operation is convenient, safe and reliable; the handle support plate of the present invention and The handle adopts a lever principle, which is easy to operate, labor-saving and high in work efficiency.

Description

technical field [0001] The invention relates to an oil seal assembly tool, in particular to a hydrostatic pump motor oil seal assembly process device and method. Background technique [0002] The existing pump motor oil seal assembly method is to take the skeleton oil seal of model SG65×90×12 as an example, place it horizontally on the end cover of the pump motor, align the inner hole of the oil seal with the hole of the end cover, and use a wooden hammer to evenly seal the oil seal along the edge of the oil seal. Tap to enter. This assembly method has several disadvantages. First, this type of oil seal is made of HG4-692-67 material, and a spring is installed inside. Knocking may easily cause the internal spring to loosen. After the spring fails, the pump motor will leak oil. The second is that in the process of knocking, due to uneven force and direct knocking on the oil seal, it is easy to crack the oil seal. The third is that the uneven force of knocking back and forth...

AI Technical Summary

Problems solved by technology

This assembly method has several disadvantages. One is that this type of oil seal is made of HG4-692-67 material, and there is a spring inside. Knocking may easily cause the internal spring to loosen. After the spring fails, the pump motor will leak oil.

Second, in the process of knocking, due to uneven force and direct knocking on the oil seal, it is easy to crack the oil seal

The third is that the uneven force of knocking back and forth will cause the oil seal assembly to be biased, and it must be replaced when disassembling and reinstalling, which not only wastes costs, but also affects work efficiency.

Therefore, the assembly method of the oil seal seriously affects the quality of the oil seal, and also causes the quality failure of the pump motor due to oil leakage caused by the crack of the oil seal.
