Embodiment 1

[0029] Such as Figure 1-5 As shown, a device for adjusting the height of an impeller by press-fitting includes a connection plate 1, a pressure head 2 and a fixed core 3. The bottom of the connection plate 1 is connected with a pressure head 2, and a through hole 14 is provided in the pressure head 2. , the upper part of the through hole one 14 is provided with threads, and the upper part of the through hole one 14 is threadedly connected with an adjustable nut 6. When in use, the indenter and the connecting plate have a clearance fit, and the pressure can be adjusted by rotating the adjustable nut. High height, simple structure, convenient adjustment, no need to remake related equipment, reduce the workload of the staff, save time, improve the test efficiency and save costs in the test products that need frequent adjustment. The outside of the adjustable nut 6 is provided with threads, and the outside of the adjustable nut 6 is threadedly connected with a lock nut 7. When in...

Embodiment 2

[0032] Such as Image 6 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that a sealing ring 8 is provided at the connection between the bottom of the fixed core 3 and the impeller 15, and when in use, the gap between the fixed core and the impeller can be increased. The friction between the impellers can be fixed on the fixed core under the friction force.

Embodiment 3

[0034] Such as Figure 7 As shown, the structure of this embodiment is basically the same as that of Embodiment 2, the difference is that: the through hole 2 4 is provided with an internal thread, the upper part of the pressure head 2 is provided with an external thread, and the pressure head 2 is threaded It is fixed on the bottom of the connection plate 1, and it is convenient to disassemble and install the connection plate and the indenter when in use, and it is convenient to use.

Abstract

The invention discloses an impeller press fitting height adjusting device, and belongs to the technical field of automobile water pump impeller mounting equipment. The impeller press fitting height adjusting device comprises a connecting disk (1), a pressure head (2) and a fixed core (3), wherein the pressure head (2) is connected to the bottom of the connecting disk (1); a through hole I (14) isformed in the pressure head (2); threads are formed in the upper part of the through hole I (14); an adjustable nut (6) is connected to the upper part of the through hole I (14) through threads; threads are formed outside the adjustable nut (6); a locking nut (7) is connected to the outside of the adjustable nut (6) through the threads; the fixed core (3) is arranged in the through hole I (14), and comprises a first part (3-A), a second part (3-B), and a third part (3-C); the first part (3-A) is arranged in the adjustable nut (6); and a spring (9) sleeves the second part (3-B). Through adoption of the impeller press fitting height adjusting device disclosed by the invention, the problem that the impeller press fitting height is inconvenient to adjust is solved, the operation is simple, andthe testing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of installation equipment for impellers of automobile water pumps, in particular to an impeller press fitting height adjustment device. Background technique [0002] Impeller press-fitting is generally the last process in the water pump assembly. During the press-fitting process of the water pump impeller, the impeller needs to be press-fitted on the pump shaft with a pressure head, but in the process of operation, the position of the impeller press-fitting needs to be controlled. , the traditional solution is to set limit posts on both sides of the equipment to control the height of the impeller press-fitting, but since the limit posts are fixed on both sides of the equipment, in the test that needs to adjust the press-fit height many times, It often fails to meet the proper range required by the installation, so it is necessary to adjust the distance between the limit column and the fixed core, and press a...
