In the process of diesel engine assembly, in order to ensure product quality, it is necessary to torque the fastening nuts of the assembled gear chamber, bearings, and hydraulic pump gears according to the process requirements. Since there is no effective fixing device to fix them, in the actual assembly process, Workers can only clamp the gear of the hydraulic pump with a vise, and then use a wrench to torque the fastening nut. This method of operation has low work efficiency, high labor intensity, and is easy to damage the gear of the hydraulic pump, thereby affecting the quality of the hydraulic pump.

Embodiment Construction
[0023] The present invention will be further described below in conjunction with the specific embodiments in the accompanying drawings.
[0024] refer to Figure 1-5 , a hydraulic pump gear tightening device of the present invention includes a workbench 1 on which an adjusting plate 3 for supporting the gear chamber 2 is detachably arranged. The height of the adjusting plate 3 can be adjusted according to the nut 5 to be tightened. Properly change the tightening state of the gear 7 to be fastened. In actual application, the gear chamber 2 is fixedly attached to the top surface of the adjustment plate 3, and there is also a clamp on the work table 1 that can clamp the adjustment plate 3 and the gear chamber 2. The clamping device 4 on the workbench 1 is to prevent the gear chamber 2 from shaking during the tightening process. At one end of the adjusting plate 3, there is a positioning sleeve 6 that can accommodate the nut 5 to be tightened to fix it. An isolation gap 12 is pro...
