Embodiment Construction

[0042] The present invention will be further described below in conjunction with the examples and drawings, but the embodiments of the present invention are not limited thereto.

[0043] see Figure 5-Figure 11 , a method for processing a vane pump rotary vane of the present embodiment, comprising the following steps:

[0044] (1) Cutting: Select graphite sheet 1 and cut it according to the specifications.

[0045] (2) End face milling: first carry out rough milling to the first end face of the graphite sheet 1; then turn over the graphite sheet 1, carry out rough milling on the second end face, and then carry out fine milling on the second end face; finally, Turn over the graphite sheet material 1 again, and carry out fine milling processing to the first end face; The two sides of the finished sheet, these two sides are matched with the rotary vane groove in the rotor when used, there is no need to separately process the two sides of the rotary vane in the subsequent proces...

Abstract

The invention discloses a method for machining a vane of a graphite vane pump. The method comprises a step (1) of cutting, a step (2) of ablaengen, a step (3) of location hole drilling, a step (4) ofslitting, a step (5) of polishing and a step (6) of slicing. According to the method, vane machining precision can be ensured, the machining cycle is shortened, production efficiency is improved, andthe rate of finished products is high. In addition, the invention further discloses a special sawing machine clamp and a special milling machine clamp used by the machining method. The special sawingmachine clamp has very high adsorption capacity, and it is ensured that a graphite strip unit does not move in the process of forming the graphite strip unit; and by adopting the special milling machine clamp, a plurality of vanes can be machined, and machining efficiency is improved.

Description

technical field [0001] The invention relates to a part processing method of a graphite vane pump and a special fixture thereof, in particular to a processing method of a graphite vane pump rotary vane and a special fixture thereof. Background technique [0002] The vane pump vane is installed on the vane slot of the rotor. When the vane pump is working, the vane rotates with the rotor and reciprocates on the vane slot of the rotor. The vane is an important part of the vane pump. Its processing quality It will directly affect the working effect of the vane pump. Among them, the upper and lower end faces of the rotary vane cooperate with the end face of the inner cavity of the stator when working, and there are high requirements for the size, parallelism and flatness between the upper and lower end faces. [0003] The graphite rotary vane has the characteristics of small size, thin thickness, wear resistance and good brittleness. At the same time, the rotary vane needs to wor...
