An impeller and bush assembly machine

Abstract

The invention relates to an assembling machine for impellers and linings. The assembling machine comprises a rotary fixing rack and a pressure-transferring rack. The rotary fixing rack comprises a six-rowed frame. A circular hole is formed in the center of the six-rowed frame. A U-shaped hole is formed in each side end face of the six-rowed frame. A U-shaped groove matched with each U-shaped hole is formed in the inner side of the corresponding U-shaped hole. A circular ring is fixed to the lower end of the six-rowed frame. Four sliding supporting seats are uniformly arranged at the lower end of the circular ring. A circle of inner teeth are arranged on the inner side face of the circular ring. A first driving wheel is engaged with the inner teeth. The first driving wheel is connected with a first motor. An auxiliary block with the diameter being equal to that of a circular hole is fixed in the six-rowed frame. A notch matched with the U-shaped grooves is formed in one side of the auxiliary block. According to the assembling machine, the rotary fixing rack can rotate automatically, automatic replacement and feeding of workpieces to be assembled are achieved, and the automation level is improved; under the intermittent thrust of a rotating disc, assembly of the linings and the corresponding impellers is achieved through the cooperation of the pressure-transferring rack and the six-rowed frame, and manual labor amount is reduced.

Description

technical field [0001] The invention relates to the technical field of auto parts processing equipment, in particular to an impeller and bushing assembly machine. Background technique [0002] In the cylinder of the automobile engine, there are many water channels for cooling water circulation, which are connected with the radiator (commonly known as the water tank) placed in the front of the automobile through water pipes to form a large water circulation system. On the upper water outlet of the engine, there is a A water pump, driven by the fan belt, pumps out the hot water in the water channel of the engine cylinder and pumps in the cold water. [0003] The impeller in the water pump rotates under the drive of the driving device. In order to improve the life of the impeller, a bush made of copper alloy with good wear resistance is usually installed on the shaft hole of the impeller, and the bush and the shaft hole of the impeller need to be used Interference fit is used ...

Problems solved by technology

[0003] The impeller in the water pump rotates under the drive of the driving device. In order to improve the life of the impeller, a bush made of copper alloy with good wear resistance is usually installed on the shaft hole of the impeller, and the bush and the shaft hole of the impeller need to be used Interference fit is used to improve the tightness of the combination of the two. However, interference fit assembly is difficult and requires high pressing force. In order to improve the efficiency of interference fit assembly, people need a method for impeller and bushing interference assembly. special device for
