Description

Technical Field

[0001] The utility model relates to the technical field of supercharger housing processing, and specifically, to an adjustable positioning device for supercharger housing processing. Background Technique

[0002] A supercharger is an important part used in an automobile. It mainly pre-compresses the air before it enters the cylinder, increases the intake air volume and improves the air density. Therefore, the supercharger is very important among automobile parts. There are also many types of superchargers, and different superchargers can be selected and installed according to actual needs. During the processing of the supercharger housing, a fixture is needed to position and fix it for processing operations.

[0003] After retrieval, the utility model patent with the publication number of CN210790095U discloses an adjustable tooling fixture for supercharger housing processing. An adjusting structure is connected above the clamping device, a fixing structure is connected to the adjusting structure, and a rotating structure is provided at the bottom of the clamping device. Through the drive of the telescopic column, the output end of the telescopic column can push the movable plate to move along the chute, so as to adjust the distance between the movable plate and the fixed plate to cope with different supercharger housings, making the utility model more practical. By rotating the adjusting rod, the adjusting rod can push the clamping plate to move. Since the clamping plate is movably connected to one end of the adjusting rod at the rear side, a cushion layer made of rubber is fixedly connected to one side of the clamping plate, which can increase the stability of the connection between the clamping plate and the housing. The working platform can be made more stable after being connected to the rotating structure through the reinforcing plate, and the working platform can be driven to rotate by the motor. By rotating the working platform, the processing position of the housing can be adjusted, making the processing more convenient and efficient.

[0004] However, the above patent still has the following deficiencies: Although the supercharger housing can be clamped and fixed through the cooperation of the baffle and the clamping plate, when processing and clamping multiple supercharger housings, it is not convenient to ensure that the clamping and fixing positions of each housing are the same, which affects the processing accuracy; and there are differences in the external dimensions of the supercharger housings, and it is not convenient to adjust the clamping plate to a suitable height to firmly clamp the housing. For this reason, we propose an adjustable positioning device for supercharger housing processing. Content of the Utility Model

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide an adjustable positioning device for supercharger housing processing.

[0013] Compared with the prior art, the advantages of the present utility model are as follows:

[0014] (1) In this utility model, the supercharger housing is placed on the clamping platform. The second motor drives the first bevel gear to rotate. Through the screw-thread fit between the first bevel gear and the second bevel gear, the lead screw is driven to rotate. By the screw-thread fit between the lead screw and the clamping block, the clamping block is driven to move. The clamping block is used to clamp and fix the supercharger housing on the top surface of the clamping platform. At the same time, multiple clamping blocks can clamp the transformer housing in the middle of the top surface of the clamping platform, realizing clamping and fixing the transformer housing at the same position on the top surface of the clamping platform, which improves the practicability of the positioning device.
