Machining Technology of the Eccentric Circle of the Joint Part of the Pump Body

Abstract

The present invention relates to the field of mechanical processing of pump bodies, in particular to a process for processing eccentric circles at the junction of pump bodies. The last eccentric circle is processed by an L-shaped tool holder. The processing process is as follows: a. Remove the first area to be processed The remaining part of the lower surface of the abdominal cavity; b. Remove the lower half of the straight wall part of the second area to be processed; c. Remove the rounded part of the second area to be processed close to the lower surface of the abdominal cavity, and first process the rounded corner counterclockwise part, and then process clockwise to remove the second half of the rounded part; d, remove the remaining part of the upper surface of the abdominal cavity in the first area to be processed; e, remove the upper half of the straight wall part of the second area to be processed ; f. To remove the rounded part of the second area to be processed close to the upper surface of the abdominal cavity, first remove the first half of the rounded part counterclockwise, and then remove the second half of the rounded part clockwise. The invention solves the processing problem of the last eccentric circle and ensures the processing quality.

Description

technical field [0001] The invention relates to the field of mechanical processing of a pump body, in particular to an eccentric circle processing technology of a joint part of a pump body. Background technique [0002] In the process of pump body processing, eccentric circle processing is often required at the junction of the pump body abdominal cavity. If multiple eccentric circles are designed within the basic circle of the pump body abdominal cavity, the radius of the machining rotation area of ​​the last eccentric circle will be very small. Such as Figure 1~4 As shown, the eccentric circles in the basic circle of the abdominal cavity of the pump body are smoothly connected in turn to form an arc-shaped cavity wall, and the last eccentric circle has the largest depth of the abdominal cavity, and the radius of the machining rotation area is the smallest. In the above-mentioned machining rotation area, once out of this area, the tool holder of the tool will touch the basi...

AI Technical Summary

Problems solved by technology

like Figure 1~4 As shown, the eccentric circles in the basic circle of the abdominal cavity of the pump body are smoothly connected in turn to form an arc-shaped cavity wall. The depth of the abdominal cavity of the last eccentric circle is the largest, and the radius of the machining rotation area is the smallest. In the above-mentioned machining rotation area, once out of this area, the tool holder of the tool will touch the basic circle, and in such a narrow space, ordinary tool holders cannot enter, and the tool protrudes too long, which is prone to tool strength. The problem is that it is not enough to cut, and it is difficult to align multiple eccentric circles at the same time. There is no tool setting reference, and it is impossible to measure the size of the eccentric circle after machining.
