Detection device for center distance of circular arcs on two sides of inner wall of piston bridge and application method of detection device

Abstract

The invention discloses a detection device for center distance of circular arcs on two sides of the inner wall of a piston bridge, which is provided with a workbench, wherein a locating stopper and a meter frame are arranged on the workbench; the locating stopper is provided with a notch and a shaft hole; the shaft hole penetrates through the locating stopper from the top to the notch; a detection sliding block is inserted into the notch; the detection sliding block is provided with a locating hole; the detection end of the detection sliding block is a circular arc of which the radius is equal to the standard radius of the circular arcs on the two sides of the inner wall of the piston bridge; a locating core shaft is arranged in the shaft hole; a length measuring device is fixed on the meter frame; and a spring is fixed on the locating stopper. The application method comprises the following steps: inserting the locating core shaft into the shaft hole, locating the detection sliding block, and adjusting the reading of the length measuring device to zero; and lifting the locating core shaft, and abutting the swash plate socket of the piston against the detection sliding block, thus the reading of the length measuring device is the error of the center distance between circular arcs on the two sides of the inner wall of the piston bridge. The detection device and method have the advantages of high detection precision, are convenient in operation, and can meet the requirements for industrial production.

Description

technical field [0001] The present invention relates to a detection device and usage method of the arc center distance on both sides of the inner wall of the piston bridge part, more specifically to a detection device and the use thereof The method belongs to the technical field of automobile air-conditioning compressor manufacturing. Background technique [0002] Existing automobile air-conditioning compressor adopts swash plate type automobile air-conditioning compressor mostly, and the piston two ends of swash-plate type automobile air-conditioning compressor are cylinder shape, and the middle is swash plate socket. The two ends of the piston are the part between the cylinders, that is, the axial corresponding part of the swash plate socket, which is called the piston bridge. There are two arcs on both sides of the inner wall of the bridge. In the production of automobile air-conditioning compressors, the center distance of the two arcs on the two sides of the inner wall...
