Automatic detection mechanism of automobile air-condition compressor valve body

Abstract

The invention discloses an automatic detection mechanism of an automobile air-condition compressor valve body. The automatic detection mechanism comprises a machine frame, wherein the machine frame is provided with an index plate through a rotary shaft, the side face of the index plate is provided with at least three station grooves, the rotary shaft is connected with a driving shaft used for driving through a rotary shaft transmission assembly, the driving shaft is connected with a cam through a cam transmission assembly, the position, on one side of the index plate, of the end face of the machine frame is provided with a detection part, the detection part comprises a fixed base and a lifting detection head, an elastic part is disposed between the lifting detection head and the fixed base, the top of the lifting detection head extends to one side to form a ball head stretching into the upper concave spherical face and the lower concave spherical face of the valve body, the bottom of the lifting detection head extends to one side to form a bending portion, and the curved face of the cam abuts against the end face of the bending portion. The automatic detection mechanism achieves detection automation of the valve body, improves detection efficiency, reduces labor intensity of workers, and guarantees stability and reliability of transmission precision.

Description

technical field [0001] The invention relates to a detection technology for automobile air-conditioning accessories, in particular to an automatic detection mechanism for a valve body of an automobile air-conditioning compressor. Background technique [0002] The air conditioner compressor is an essential device for temperature regulation in the car, and its main function is to compress and transport refrigerant. The valve body is the core part of the air-conditioning compressor, please refer to figure 1 as shown, figure 1 It is a schematic diagram of the structure of the valve body of an automobile air-conditioning compressor. There is a plane 161 at its upper end, a C-shaped groove 163 at the top, and an upper concave spherical surface 162 and a lower concave spherical surface 164 at the opening of the C-shaped groove 163. The upper concave spherical surface 162 and the lower concave spherical surface The spherical surfaces 164 are oppositely arranged to cooperate with th...

Problems solved by technology

At present, there is no special automatic testing equipment for this valve body product, and it is completely classified by manual testing. This kind of testing has the following disadvantages: (1) manual operation, the risk of random errors is great; (2) the parts are small in size and large in number, and The accuracy level is high, and the measurement process requires hand-eye coordination. At the same time, it is necessary to observe and record the measurement data. The work intensity is high, which is prone to visual fatigue and increases the probability of workers suffering from visual diseases; (3) The output of the test is easily affected by factors such as worker fatigue. impact, yield instability
