Problems solved by technology

[0010]The purpose of the present invention is to solve the existing water pump water seal installation, when the assembly force is transmitted to the ball through the pump shaft, there will be a relative gap between the ball and the raceway. The force causes the balls and raceways to leave marks, so that the bearings leave hidden troubles. A new water pump water seal installation method and tooling are proposed. This water pump water seal installation method and tooling can effectively prevent when the assembly force passes through. After the pump shaft is transferred to the ball, a relative force will be generated between the ball and the raceway, causing the ball and the raceway to leave marks

Embodiment 1

[0030] The wedge iron self-locking adjustment mechanism 2 includes an upper wedge iron 6 and a lower wedge iron 7, wherein the upper wedge iron 6 is connected with the moving block 8 installed in the shaft hole 16 of the water pump, and the upper wedge iron 7 only It can move up and down together with the moving block 8; the lower wedge iron 7 is located under the upper wedge iron 6, and the upper wedge iron 6 and the lower wedge iron 7 adopt self-locking slopes to be close together.

[0031] There is a screw hole 9 on the side of the lower wedge iron 7, one end of the manual adjustment handle 3 is installed in the screw hole 9, and the other end of the manual adjustment handle 3 is installed on the side of the water pump water seal installation tool base 1. Manually adjust the inside of the handle sleeve 10.

[0032] The manual adjustment handle 3 is covered with a compression spring 11, one head of the compression spring 11 is placed on the side of the lower wedge iron 7, an...

Embodiment 2

[0038] The water pump water seal installation tool base 201 is one piece, and a water pump shaft hole 216 is vertically opened on the upper end surface of the water pump water seal installation tool base 201, and a floating moving block capable of moving up and down is installed in the water pump shaft hole 216 208; There is a wedge iron installation hole 215 on the side of the water pump water seal installation tooling base, and the upper wedge iron 206 and the lower wedge iron 207 are installed in the wedge iron installation hole 215, and the upper wedge iron 206 and the floating moving block 208 are threaded. Firmly connected together, so that when the upper wedge iron 206 reciprocates laterally in the lower wedge iron 207, the upper wedge iron 206 can only drive the floating moving block 208 to move up and down.

Abstract

The invention provides a water pump water seal floating assembly method and a floating tool. A floating adjusting device is disposed in a water pump water seal installation tool base, the floating adjusting device is made to make contact with the bottom of a water pump shaft all the time in the water seal installation process, accordingly axial action force generated in the water seal installation process is transmitted to the floating adjusting device through the water pump shaft and then transmitted to the tool base through the floating adjusting device, and influences of axial action force on a bearing are eliminated in the water seal installation process. The situation that distance changes of the shaft end of a water seal and the end face of a water pump body is affected by errors between accessories is compensated for through a floating wedge self-locking adjusting mechanism, so that the wedge self-locking adjusting mechanism is closely attached to the lower end face of the water pump shaft. In the water pump water seal installation process, the axial action force for installing the water seal is transmitted to the water pump water seal installation tool base through the wedge self-locking adjusting mechanism, axial-action-force-free floating installation of the water pump water seal bearing is achieved, a wedge makes contact with the bottom of the shaft all the time, and damage of assembly force from the shaft to the bearing is offset.

Description

technical field [0001] The invention relates to a water pump assembly method and assembly tooling, in particular to a water pump water seal installation method and assembly tooling, the water pump water seal installation method and assembly tooling can effectively solve the problem of water pump water seal assembly process The errors produced in the manufacturing process of water pump parts make it possible for the water pump to effectively solve the problem of assembly force acting on the bearing when assembling the water seal, and eliminate the potential failure of the bearing due to assembly resistance. Background technique: [0002] The function of the water seal is to play the role of sealing, which is to use the effect of water to prevent material leakage; the other is to cool and lubricate the sealing surface to reduce the wear on the shaft. The pump water seal is to use a balance between the high-pressure water and the internal pressure of the pump, which is equival...
