Automatic detection device for valve core of automotive air conditioner

Abstract

The invention discloses an automatic detection device for a valve core of an automotive air conditioner. The automatic detection device comprises a pedestal, a material feeding mechanism, a detection guide rail, a driving component and a detection head component, wherein the material feeding mechanism is arranged on the pedestal; a feeding hole, a material guiding trough and a discharging hole are formed in the detection guide rail; the discharging end of the material feeding mechanism corresponds to the position of a material conveying hole; the detection head component is located above the material guiding trough; the driving component for driving the valve core in the material guiding trough to move is mounted corresponding to the material guiding trough. According to the automatic detection device for the valve core of the automotive air conditioner, the valve core is automatically detected; the detection efficiency is increased, and the labor intensity of a worker is greatly reduced; the stability and reliability of the transmission accuracy are guaranteed due to a pure mechanical structure design.

Description

technical field [0001] The invention relates to a detection technology for automobile air conditioner accessories, in particular to an automatic detection device for a valve core of an automobile air conditioner. 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 spool is the core part in the piston of the air conditioner compressor, please refer to figure 1 as shown, figure 1 It is a structural schematic diagram of the spool of an automobile air-conditioning compressor. The spool is hemispherical and includes a flattened top end 40. The flattened top end 40 is smoothly connected to a spherical surface 41 through rounded corners. A cylindrical section 42 extends from the bottom of the spherical surface 41. There are also smooth transitions with rounded corners. [0003] In order to ensure the matching tolerance between the valve core ...

AI Technical Summary

Problems solved by technology

At present, there is no special automatic testing equipment for this spool 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 very high; (2) the size of the parts is small (about 13mm) and the quantity It is large and has a high level of precision. Manual work needs to be done repeatedly, such as loading, testing, recording, and unloading, which is prone to visual fatigue and increases the chance of workers suffering from visual diseases; (3) The output of testing is easily affected by worker fatigue. Influenced by other factors, the output is not stable
