Problems solved by technology

There are deficiencies in the above detection method: 1. There are measurement errors in the measured distance between the center of the two-section arc of the piston and the thickness of the slant plate; , the last selected hemisphere deviates from the actual calculated value
The above two points lead to a large error in the final actual matching result

Embodiment Construction

[0026] see figure 1 , image 3 , the fixed structure of the swash plate includes two V-shaped positioning seats 3, the heights of the two V-shaped positioning seats 3 are the same, and the two V-shaped positioning seats 3 are provided with a pressure block 6. The inner side of one of the V-shaped positioning seats 3 is provided with a swash plate axial positioning rod 4, and the outside of the other V-shaped positioning seat 3 is provided with a swash plate axial tightening member 5, and the axis of the axial positioning rod 4 is in line with the two The central line of the two V-shaped positioning seats is vertical, and the axial tightening member 5 of the swash plate can adopt some tightening structures in the existing mechanical field. To save space, it will not be described in detail here.

[0027] The piston support includes two piston rest blocks 8 with grooves 7 fixed on the workbench 1. In order to make the piston 10 have a better limit during the test, the two sides...

Abstract

The invention discloses a detection device of a swash plate and piston axial matched gap and a using method thereof. The detection device comprises an operating platform, and a swash plate fixed structure, a piston support and a displacement measurement mechanism are arranged on the operating platform. The piston support comprises two piston placing blocks provided with grooves and fixed on the operating platform, and a pit is arranged in the middle position at the bottom of the groove of one piston placing block. The positions of the piston placing blocks are that when two ends of a piston are placed in the grooves of the piston placing blocks, a swash disc fixed on the swash plate fixed structure is right inserted in a swash disc socket of the piston, an axis of the piston and an axis of the swash disc fixed on the swash plate fixed structure are in a same horizontal height, and measure points of the displacement measurement mechanism is placed at the bottom of one end of the piston on the groove with the pit. The detection device of the swash plate and piston axial matched gap can improve selection and matching accuracy to meet requirements of volume production, and the using method has the advantages of being simple and convenient in operation.

Description

technical field [0001] The present invention relates to a detection device and a use method for the axial cooperation gap between the swash plate and the piston, more specifically a detection device and the use method for the axial cooperation gap between the swash plate and the piston of the swash plate type automobile air-conditioning compressor. Automotive air-conditioning compressor manufacturing technology field. 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. There are two circular arcs on both axial sides of the inner wall of the swash plate socket. During the operation of the automobile air-conditioning compressor, two hemispheres need to be installed on the two sides of the inner wall of the swash plate socket of the piston. The...
