Measuring equipment for eccentric shaft

Abstract

The invention relates to measuring equipment for an eccentric shaft, which is easy to determine the radial dimension of a part on the outer peripheral surface of the eccentric shaft. The measuring equipment for the eccentric shaft is used for measuring an eccentric shaft which is used by a compressor and provided with a shaft main body and an eccentric portion eccentric relative to a rotary centerline of the shaft main body. The measuring equipment comprises a supporting part, a driving part, a measuring part and a control part, wherein the supporting part is used for supporting the eccentricshaft to rotate around the rotary center lien of the shaft main body; the driving part is used for enabling the eccentric shaft supported by the supporting part to rotate around the rotary center line of the shaft main body; the measuring part is provided with a contact and a conversion portion, the contact is set to be abutted with the outer peripheral surface of the eccentric shaft supported bythe supporting part, move in a preset direction perpendicular to the rotary center line of the shaft main body of the eccentric shaft along with the rotation of the eccentric shaft and output position information, and the conversion portion obtains the radial dimension of the part on the outer peripheral surface of the eccentric shaft according to a corresponding relation between the position information output by the contact and the radial dimension of the part on the outer peripheral surface of the eccentric shaft; and the control part controls the operation of the measuring equipment 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
