Polishing device for electronic expansion valve production

Abstract

The invention discloses a polishing device for electronic expansion valve production. The polishing device comprises a roller, a top plate, a bottom plate and a sieve plate, springs are fixedly installed at the two ends of the top surface of the bottom plate, the top plate is fixedly installed at the top ends of the springs, the output end of a first motor is connected and installed in the middle of the bottom surface of the top plate, and the first motor is installed at the top end of a support through bolts and threads; and the support is fixedly installed in the middle of the top surface of the bottom plate, shaft seats are fixedly installed at the two ends of the top surface of the top plate, the roller is rotatably installed in the shaft seats, inserting grooves are formed in the two sides of the interior of the roller, and inserting plates are inserted into the inserting grooves and arranged at the two ends of the sieve plate. A vibration motor is used for driving abrasive sand in the roller to vibrate, so that the expansion valve in the abrasive sand is polished and ground, a rotating mechanism is used, the abrasive sand can flow away through screen holes through rotation during discharging, the expansion valve is left on the surface of the sieve plate, the expansion valve can be conveniently taken out at a time and used by workers conveniently, efficiency is improved, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of polishing, in particular to a polishing device for electronic expansion valve production. Background technique [0002] As a new type of control element, the electronic expansion valve has become an important part of the intelligentization of the refrigeration system, and it is also an important means and guarantee for the real realization of the optimization of the refrigeration system. It is applied in more and more fields. The application of electronic expansion valve will become more and more mature with the progress and development of technology. [0003] The existing electronic expansion valve needs to go through a polishing step during manufacture. Due to the irregular shape of the electronic expansion valve, a vibration polishing machine is often used for polishing. Picking out in the grinding, if most electronic expansion valves are polished and polished, it will take a lot of time to pick them ...

Problems solved by technology

[0003] The existing electronic expansion valve needs to go through a polishing step during manufacture. Due to the irregular shape of the electronic expansion valve, a vibration polishing machine is often used for polishing. Picking out in the grinding, if most electronic expansion valves are polished and polished, it will take a lot of time to pick them out manually, which wastes time and energy and reduces production efficiency
