Grooving device for outer surface of lining

Abstract

The invention relates to a grooving device for the outer surface of a lining. The grooving device comprises a bottom plate. A clamping device is arranged on the left side of the bottom plate. A cutting device is arranged on the right side of the bottom plate and comprises a slideway on the bottom plate, a sliding frame in the slideway, a threaded rod arranged on the right side of the sliding frame, a first air cylinder installed on the upper portion of the sliding frame, an installation plate installed on a shaft of the first air cylinder, a motor installed on the installation plate and a cutting piece installed on a shaft of the motor. A sheave driving mechanism is used for driving a supporting frame used for containing the lining to rotate, intermittent rotation of the supported lining can be realized, and therefore the purpose of evenly grooving the lining is realized. Compared with an existing driving method through a stepping motor, a controller is eliminated, the cost is reduced, and the work stability is good. A sliding plate is pressed through an inverted circular truncated cone pressing block.

Description

technical field [0001] The invention relates to the technical field of auto parts processing equipment, in particular to a device for opening grooves on the outer surface of a bush. Background technique [0002] On the upper water outlet of the engine, a water pump is installed, which is driven by the fan belt to pump out the hot water in the water channel of the engine cylinder and pump in the cold water. [0003] The impeller in the water pump generally rotates under the drive of the rotating shaft. In order to improve the life of the impeller, a bush made of copper alloy with good wear resistance is usually installed at the shaft hole of the impeller, and the bush and the shaft hole of the impeller need to be used Interference fit to improve the tightness of the two, however, the relative sliding between the bush and the shaft hole will still occur during long-term use, which will reduce the rotation speed of the impeller and affect the cooling performance of the water pu...

Problems solved by technology

[0003] The impeller in the water pump generally rotates under the drive of the rotating shaft. In order to improve the life of the impeller, a bush made of copper alloy with good wear resistance is usually installed at the shaft hole of the impeller, and the bush and the shaft hole of the impeller need to be used Interference fit to improve the tightness of the combination of the two. However, during long-term use, there will still be relative sliding between the bush and the shaft hole, which will reduce the rotation rate of the impeller and affect the cooling performance of the water pump. Therefore, people usually use it on the side of the bush. There is a groove on the upper surface, and the bush is clamped in the shaft hole by using the groove. However, the outer surface of the bush is a curved surface, which is difficult to process and clamp.
