Measuring equipment for eccentric shafts

Abstract

Disclosed is a measuring device for an eccentric shaft, which can easily determine the radial dimension of the portion on the outer peripheral surface of the eccentric shaft. The eccentric shaft measuring device of the present invention is used for measuring an eccentric shaft used in a compressor, which has a shaft main body and an eccentric portion eccentric with respect to the rotation center line of the shaft main body, and includes: a support portion for supporting the eccentric shaft so as to be able to rotate around The rotation center line of the shaft main body rotates; the driving part is used to rotate the eccentric shaft supported on the support part around the rotation center line of the shaft main body; The outer peripheral surface of the supported eccentric shaft abuts, and moves in a preset direction perpendicular to the rotation center line of the shaft body of the eccentric shaft with the rotation of the eccentric shaft, and outputs position information, and the conversion part outputs position information according to the contact The correspondence relationship with the radial dimension of the portion on the outer peripheral surface of the eccentric shaft is used to obtain the radial dimension of the portion on the outer peripheral surface of the eccentric shaft; and a control unit controls the operation of the measuring device for the eccentric shaft.

Description

technical field [0001] The present invention relates to a measuring device for an eccentric shaft for measuring the dimension of an eccentric shaft used in a compressor having a shaft main body and an eccentric portion eccentric with respect to the rotation center line of the shaft main body. Background technique [0002] In the past, there was a compressor, which included: an eccentric shaft, such as Figure 6 It has a shaft main body 311X and an eccentric portion 312X protruding radially outward from an axial middle portion of the shaft main body 311X; a first bearing supporting one end side of the eccentric shaft; a cylinder body, the The cylinder block has a storage chamber for storing the eccentric portion; and a second bearing supporting the other end side of the eccentric shaft, and supporting one end side of the eccentric shaft by the first bearing, In a state where the cylinder accommodates the eccentric portion and the second bearing supports the other end of the e...

Problems solved by technology

[0004] However, in the above-mentioned compressor, since the shaft main body 311X of the eccentric shaft protrudes from the eccentric portion 312X toward both ends in the axial direction, the measurement of the radial dimension of the eccentric portion 312X of the eccentric shaft is hindered, so the conventional measurement efficiency is usually very low. , significantly restricting the manufacturing efficiency of the compressor
