AI Technical Summary

Technical Problem

The existing dual pump gap measurement method is cumbersome and difficult to apply to situations where there are large quantities of products, which affects the measurement speed.

Method used

A double pump clearance measuring tool is designed, which abuts the end of the drive shaft through the thimble module in the clearance measuring unit, and twitches the drive shaft to move, indirectly measures the gap between the bottom surface of the sliding shoe and the swash plate plane, and uses transmission The shaft is slid to achieve measurement.

Benefits of technology

The speed and efficiency of the double pump clearance measurement are improved, the cumbersome problems of existing methods are solved, and the faster clearance measurement is achieved.

Abstract

The invention relates to the field of double pump clearance measurement, in particular to a double pump clearance measurement tool and a double pump clearance measurement method. Comprising a supporting unit, a first locking unit, a second locking unit, a third locking unit, a first positioning unit, a second positioning unit and a gap measuring unit. A transmission shaft is arranged in the double pump, and the clearance value between the transmission shaft and a pump body of the double pump in the axial direction of the transmission shaft is K; wherein one end of the duplex pump is fixed in the first bearing part, the other end of the duplex pump is fixed in the second cavity, the transmission shaft penetrates through the first cavity and abuts against one end of the ejector pin module, the central axis of the ejector pin module and the central axis of the transmission shaft are on the same straight line, and the displayed numerical value of the numerical value display module is K1; the transmission shaft is shifted to push the ejector pin module to move in the axial direction until the transmission shaft stops moving, and the reading of the numerical value display module is K2; and K is equal to K2-K1. In this way, the problem that an existing duplex pump gap measuring method is complex is solved.
