Technical Field

[0001] The utility model belongs to the technical field of mechanical tooling, and particularly relates to a fixing tooling for machining the hole surface of a swash plate. Background Art

[0002] A swash plate type axial piston pump is composed of a swash plate, a plunger, a block body, a valve plate and a transmission shaft. There is an inclination angle between the cylinder block and the swash plate. The plungers are evenly distributed in the cylinder block, and their heads are tightly pressed on the swash plate through the action of a spring return mechanism and oil pressure. When the transmission shaft rotates, the plungers not only rotate with the cylinder block but also make reciprocating linear motion in the plunger holes of the cylinder block.

[0003] When the existing fixing tooling for the swash plate clamps the swash plate, due to the shielding of the tooling, it is impossible to simultaneously meet the machining of the holes and surfaces of the swash plate, and only single machining can be carried out. Usually, the swash plate needs to be removed, re-clamped, and then another machining step is carried out. The operation is relatively cumbersome and the machining accuracy cannot be guaranteed.

[0004] Therefore, in order to solve the above problems, it is very necessary to provide a fixing tooling for machining the hole surface of a swash plate. Content of the Utility Model
