Problems solved by technology
If the arc groove is processed by milling, since the part requires that the bottom of the arc groove be flush with the empty groove at the bottom of the conical table, the milling cutter has a milling dead angle during milling, and the empty groove at the bottom of the conical table cannot be milled to , there will be residual material at the bottom of the arc-shaped groove, which cannot be cleaned; if EDM and powder metallurgy casting mold are used, not only the processing accuracy is poor, but also the processing efficiency is low, and the processing cost is also high

Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0024] Example. A method for processing the arc groove on the plunger type variable pump chuck, the method is to place the prefabricated plunger type variable pump chuck on the lower fixing plate of the punch press for vertical punching, and pass the punching die used for punching the arc groove One-time punching and forming, a cylindrical pin and a rhombic pin are fixed on the lower fixing plate to match with the sliding shoe hole of the chuck and play an orientation role. The prefabricated plunger type variable pump chuck is as follows: Figure 4 As shown, there is a group of sliding shoe holes 10 evenly distributed along the circumference on the part, and there is a raised conical platform 11 in the middle of the chuck. The conical platform 11 does not have an arc groove. There will be interference between the outer circles, which will aff...

Abstract
The invention discloses a processing method of an arc groove on a plunger type variable pump chuck. The processing method comprises the following steps of: fixing a prefabricated variable pump chuck on a punching machine with vertical stamping, and using the die for stamping the arc groove for one-time stamping forming; and one-time stamping forming by using the die for stamping the arc groove isas follows: a group of stamping platforms with edges are arranged at a central hole of the die plate corresponding to a central hole of the chuck along the periphery of the central hole, and then thedie is used for one-time stamping forming. The processing method not only improves the size precision of the arc groove on the chuck part, also improves production efficiency and reduces processing cost.
Description
technical field [0001] The invention relates to a method for processing an arc groove on a chuck of a plunger type variable displacement pump. Background technique [0002] There is a chuck part on the plunger type variable pump, which has a set of sliding shoe holes evenly distributed along the circumference, and a raised conical platform in the middle of the chuck, in order to prevent the conical platform from colliding with the step of the sliding shoe. Interference occurs between the circles, and a set of arc-shaped grooves corresponding to the sliding shoe holes are set along the circumference of the conical platform to avoid the sliding shoes and ensure the normal operation of the sliding shoes. [0003] Existing processing methods for arc-shaped grooves mainly include milling processing, electric discharge processing and powder metallurgy casting mold one-time die-casting processing methods. If the arc groove is processed by milling, since the part requires that the ...
