Description

Technical Field

[0001] The utility model relates to the technical field of automobile supercharger impeller manufacturing, in particular to a clamp for manufacturing automobile supercharger impellers. Background Art

[0002] The automobile supercharger impeller converts the mechanical energy of the prime mover into the static pressure energy and dynamic pressure energy of the working fluid. The impeller refers to the wheel disc equipped with moving blades, which is a component of the impulse turbine rotor. It can also refer to the general term for the wheel disc and the rotating blades installed on it. The fixture is needed in the production process of the automobile supercharger impeller.

[0003] The patent document with publication number CN218800654U discloses an impeller production fixture. In view of the poor fixing effect of the existing automobile impeller production fixture, the automobile impeller is prone to fall off when clamped and fixed, which makes the automobile impeller prone to processing damage. Therefore, the utility model proposes an impeller production fixture. The following scheme is proposed, which includes an outer shell, a tray is fixedly installed on the top of the outer shell, and symmetrically arranged clamps are arranged on the inner side of the outer shell. The number of clamps is two, and symmetrically arranged mounting plates are fixedly installed on the bottom inner wall of the outer shell. In the utility model, the clamp in the current position can be unlocked by pulling the unlocking rod, and then the handle can be rotated to control the clamp to fit with the impeller to achieve the positioning of the impeller, and then the unlocking rod is released to automatically position the position of the clamp, which greatly increases the stability of the impeller positioning.

[0004] The tray of the device in the above technical solution is fixedly installed on the top of the shell, which makes it inconvenient to rotate the tray. When other positions of the impeller need to be processed, the staff needs to walk around the device, which is very time-consuming and labor-intensive, increasing the workload of the staff, and the process of clamping the impeller is also very troublesome. The staff needs to pull the unlocking lever first and then rotate the handle, which reduces the working efficiency of the device. Therefore, we propose a clamp for manufacturing automotive supercharger impellers to solve this problem. Utility Model Content
