[0012] A valve processing device and method, comprising the valve processing device described above, and the steps are as follows:
[0013] Step 1: Open the glass door at the front end of the processing room, put the valve to be processed on the electric turntable, first grind the valve surface to remove oil, welding slag, rust, oxide scale and other impurities on the valve surface, make the valve surface smoother, and provide a good foundation for the subsequent painting work. Adsorb the grinding equipment to the fixed point magnetic seat at the lower end of the translation slot for installation and positioning, close the glass door, the glass door is equipped with a sealing strip, after closing, the processing environment in the processing room is separated from the outside world, and a relatively sealed environment is formed inside, so that the gas and dust generated by the processing valve are not easy to leak out, and the gas and dust can be centrally processed through the debris discharge channel at the lower end;
[0014] Step 2: Next, the hydraulic cylinder group is started to drive the two sets of symmetrically distributed active clamping blocks and driven clamping blocks to move inward synchronously.

The painting operation is the same as the grinding operation in step 3, and fine processing can be carried out by adjusting the rotation of the valve and the position of the paint head;
[0017] Step 5: At the same time, the linkage arms A and B of the linkage assembly can also drive the cleaning scraper at the front end to move up and down closely in contact with the surface of the glass door, effectively removing dust, paint residues and other impurities stuck to the glass door, ensuring that the staff can clearly observe every detail of the processing process through the glass door, which is conducive to monitoring the processing quality and discovering problems in a timely manner. The warm air outlet at the rear end moves up and down to achieve uniform heating of the valve surface in the processing area and accelerate the drying process of the coating, which not only shortens the processing cycle, but also improves the quality and adhesion of the coating.
[0018] Beneficial effects of the present invention:
[0019] The present invention adopts a modular quick-release design for the processing equipment, so that the polishing equipment and the paint spraying head can be replaced according to different processing requirements.

[0033] Step 2: Next, the hydraulic cylinder group 6 is started to drive the two groups of symmetrically distributed active clamping blocks 7 and driven clamping blocks 8 to move inward synchronously. At the same time, the linkage assembly at the lower end pushes the electric turntable 10 to move upward, so that the valve to be processed is stably clamped between the active clamping block 7 and the driven clamping block 8;
[0034] When the clamping action is performed, the two hinged rods 902 of the linkage assembly slide along the track groove 905 on the surface of the limit plate 901 and change the angle.
