Description

Technical Field

[0002] A valve is a device used to control the flow of fluids (such as liquids, gases, steam, etc.), usually composed of valve body, valve cover, valve core and valve seat. Valves can be used to adjust the flow, pressure, direction and other parameters of the fluid. They are widely used in various industrial fields and equipment, including pipeline systems, chemical plants, power plants, water supply systems, automobile engines, etc. In the production process of some valves, because the materials of the valves and flange rings are different, it is usually necessary to produce the valves and the flange rings at both ends of the valves separately, and then use the valve welding table to fix and weld them to produce compliant valves.

[0031] In the above technical solution, multiple second springs 402 are used to elastically connect multiple circularly distributed arc plates 401 on the rotating column 8, so that multiple flange rings can be sleeved outside the multiple arc plates 401, so that the utility model can shorten the time of sleeved flange rings during the continuous welding process, thereby speeding up the entire welding process and improving the efficiency of valve welding.

[0032] In the utility model, the pushing assembly 5 includes a cylinder 501, which is fixedly connected to the fixed plate 10. A connecting plate 502 is provided at the output end of the cylinder 501. A ring plate 503 is provided on the top of the connecting plate 502. The ring plate 503 is sleeved on the outer arc surface of the arc plate 401, and the inner diameter of the ring plate 503 is larger than the diameter of the rotating column 8.

[0033] In the above technical solution, by setting the cylinder 501 so that air can be taken in, the movement of the cylinder 501 can drive the ring plate 503 connected to the output end of the cylinder 501 through the connecting plate 502 to move toward one end of the flange ring, and then push the flange ring to move toward one end of the valve, thereby facilitating the welding between the flange ring and the valve.

[0034] In the utility model, a sliding vertical plate 11 is slidably arranged on the right side of the top of the workbench 1, and a mounting column 12 is rotatably connected to the sliding vertical plate 11. The mounting column 12 is arranged coaxially with the rotating column 8, and an elastic clamping mechanism 13 is arranged on the outer cylindrical surface of the mounting column 12 near one end of the rotating column 8.

[0035] In the above technical scheme, a sliding vertical plate 11 is slidably set on the workbench 1, and a mounting column 12 is rotatably connected on the sliding vertical plate 11, and then a flange ring can be sleeved by utilizing an elastic clamping mechanism 13 installed on the mounting column 12, so that the sliding vertical plate 11 moves to the left, which can drive the flange ring sleeved on the elastic clamping mechanism 13 to move toward one end of the principle rotating column 8 of the valve. Combined with the pushing component 5, the flange ring on the arc plate 401 is pushed toward the valve end under the push of the ring plate 503. The utility model can weld the flange rings at both ends of the valve in sequence.

[0036] It is worth noting that: the elastic clamping mechanism 13 in the present invention is similar in structure to the elastic clamping component 4, so no excessive explanation is given in the present invention, and a pushing component 5 can also be installed on the sliding vertical plate 11 to push the flange ring; in the present invention, the first motor 201 and the second motor 301 are both electrically connected to the external circuit through the controller, and the air inlet and outlet of the cylinder 501 are controlled by the controller.

[0037] The working principle of a valve welding platform of the utility model is:

[0038] When in use, firstly, multiple flange rings are put on multiple arc plates 401, and flange rings are put on the elastic body clamping mechanism, and then the valve is inserted on the rotating shaft, and the first motor 201 is started. The operation of the first motor 201 drives the first threaded rod 204 to rotate, and then the telescopic column 205 threadedly connected with the first threaded rod 204 can be pushed to move rightward in the telescopic groove. After the telescopic column 205 moves to the right in the telescopic groove and contacts the first inclined surface 206 and the second inclined surface 212, the first motor 201 continues to operate, and the telescopic column 205 continues to move rightward to abut and push the slider 209, and the slider 209 moves in the second slide groove 208 toward the outer cylindrical surface of the rotating column 8, and at the same time drives the second mounting plate 215 to slide away from the first mounting plate 213. The first spring 214 is stretched to fix the valve on the rotating shaft, and the cylinder 501 is started to drive the ring plate 503 to move toward the valve end. When the flange ring on the rightmost end of the arc plate 401 close to the valve side abuts against the valve, the sliding vertical plate 11 is moved toward the valve end, driving the flange ring on the elastic clamping mechanism 13 to abut against the other end of the valve. Finally, the second motor 301 is started to drive the rotating column 8 to rotate slowly, so that the flange rings at both ends of the valve can be welded.

[0039] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
