Description

Technical Field

[0001] This utility model relates to the field of electronic expansion valve nut assembly technology, and in particular to electronic expansion valve nut assembly equipment. Background Technology

[0002] Electronic expansion valves utilize electrical signals generated by the regulated parameters to control the voltage or current applied to the expansion valve, thereby achieving the purpose of regulating the liquid supply. Stepless variable capacity refrigeration systems have a wide range of liquid supply regulation and require fast adjustment response. Traditional throttling devices such as thermostatic expansion valves are difficult to perform well, while electronic expansion valves can meet the requirements very well.

[0003] The valve body of the electronic expansion valve includes a stainless steel shell, a magnetic rotor, a nut, a screw, a needle valve, a body, and a connecting pipe. The electronic expansion valve controls the up and down movement of the valve stem by rotating the motor rotor, thereby adjusting the opening of the valve needle and regulating the flow rate. The motor rotor uses a permanent magnet, and the magnetic attraction or repulsion between the magnetic poles induced by the rotor and the magnetic poles induced by the stator winding causes the rotor to rotate. The coil is controlled by a wired control motherboard, which issues control commands and applies pulse voltage to the motor stator winding to drive the rotor.

[0004] The assembly of electronic expansion valve nuts is generally done manually. However, manual assembly is inefficient, cumbersome in personnel management, and difficult to control in terms of quality, thus reducing the efficiency and quality of electronic expansion valve nut assembly.

[0005] Therefore, it is necessary to provide electronic expansion valve nut assembly equipment to solve the above-mentioned technical problems. Utility Model Content

[0044] The working principle of the electronic expansion valve nut assembly equipment provided by this utility model is as follows:

[0045] A rotating disk 17 with controllable rotation angle is installed on the top of the assembly table 6 via a drive assembly 19. Then, by simply placing eight positioning components—comprising a support plate 221, a first telescopic rod 222, a movable ring 226, a mounting frame 224, a positioning ring 223, and a contact sensor 227 mounted on a fixed base 225—each station on the rotating disk 17 can complete a portion of the assembly process, greatly improving assembly efficiency and quality while reducing costs.

Then, the drive component 19 drives the rotating plate 17 to adjust the progress at a certain angle. At the same time, it is fixed by the first telescopic rod 222 and the movable ring 226 on the corresponding positioning component. Then, the second feeding vibratory plate 11 and the third feeding vibratory plate 12 can be used to install the structure that needs to be installed inside the valve body in sequence. During this process, the movable ring 226 on the first telescopic rod 222 can contact the adjacent positioning ring 223 in sequence to fix the valve body, which is convenient for nut or structure assembly. At the same time, the quality inspection component 9 performs quality inspection.

[0046] Compared with related technologies, the electronic expansion valve nut assembly equipment provided by this utility model has the following advantages:

[0047] To improve the efficiency and quality of electronic expansion valve nut assembly, a rotating disk 17 with controllable rotation angle is installed on the top of the assembly table 6 via a drive assembly 19.
