Description
Technical Field
[0001] The utility model relates to the technical field of plunger pump part processing, in particular to a hand-held oil distribution disc tightening tooling. Background Technique
[0002] At present, there are already power tools in the prior art that can complete the grinding of the oil distribution disc, but manual grinding can never be replaced. Most of the output power of the plunger pump is affected by the matching degree between the cylinder block and the oil distribution disc. Technicians can judge the matching degree between the oil distribution disc and the cylinder block by observing the contact part of the scratch marks. In addition, before reassembling the oil distribution disc on the plunger pump, it is necessary to grind the oil distribution disc, remove the scratches and reduce the thickness of the oil distribution disc to a certain extent, and then reassemble it on the plunger pump for further testing until the plunger pump reaches the expected output power. When the expected output power is reached, the assembly of the plunger pump is completed. When grinding a single oil distribution disc, manual grinding is required. After manual grinding for a long time, it is easy to get tired, which will reduce the grinding accuracy. Moreover, there is no special tool for clamping the oil distribution disc in the existing tools, and the operator can only hold the oil distribution disc by hand for grinding. It is not only easy to slip but also difficult to control the force and angle, which is prone to safety accidents, greatly reducing the work efficiency and the operator's ability to control the grinding effect.
