Description

Technical Field

[0001] The invention relates to the field of arc welding devices, in particular to an automatic arc welding device for valve assembly. Background Art

[0002] Arc welding is the most widely used welding method in industrial production. The metal to be welded is used as one electrode and the welding rod is used as the other electrode. When the two electrodes are close to each other, an arc is generated. The heat generated by the arc discharge (commonly known as arc burning) is used to melt the welding rod and the workpiece together and form a weld after condensation, thereby obtaining a strong joint in the welding process. Valves are one of the widely used fluid control equipment. As an important part of the pipeline system, there are many specifications and types of valves, and their functions are also different. The manufacturing process of the valve will directly affect the safe operation of the pipeline equipment. Valve welding is one of the key processes in the entire manufacturing process. In order to adapt to the connection between different pipelines, it is often necessary to make a sleeve connection at the valve connection port to meet the actual pipeline connection requirements. The existing processing method is mainly to connect by welding. During the welding process, the following problems are very likely to occur:

[0003] 1. When welding the valve to the flange sleeve, the center of the sleeve needs to be aligned with the center of the valve connection port, which requires precise positioning of the valve and the flange sleeve. This makes the valve fixing process more complicated and cumbersome, leading to low valve welding efficiency.

[0004] 2. At the same time, since the welded valve needs to be inspected, it is necessary to wait for the welded part to cool down before manual inspection, which makes the inspection of the valve after welding extremely inconvenient. Summary of the Invention

[0041] See also Figure 6 The cleaning mechanism 20 includes a storage bucket 201, which is placed on the top of the support platform 1. An industrial vacuum cleaner 202 is fixedly installed on the top of the support platform 1. A suction tube 203 is fixedly sleeved on the side of the industrial vacuum cleaner 202, and one end of the suction tube 203 is fixedly sleeved on the top of the storage bucket 201; by setting the cleaning mechanism 20, when the valve welding process is carried out, the industrial vacuum cleaner 202 is started, so that the industrial vacuum cleaner 202 can absorb the air inside the protective cover 22 through the storage bucket 201, so that the metal debris inside the protective cover 22 can enter the storage bucket 201 along with the air, thereby achieving the effect of collecting welding debris, avoiding the problem of difficult cleaning when welding debris falls into the interior of the welding device, thereby improving the cleanliness of the interior of the welding device.

[0042] See also Figure 1 and Figure 6 One end of the absorption tube 203 is fixedly connected with a filter cover 24, and the material of the filter cover 24 is activated carbon material. By setting the filter cover 24, when absorbing welding exhaust gas, the filter cover 24 can adsorb and filter nitrogen oxides in the exhaust gas, thereby avoiding the problem of nitrogen oxides being directly discharged into the air during exhaust gas discharge, causing the air around the welding device to be polluted, thereby improving the cleanliness of the valve during welding.

[0043] The working principle of the present invention is as follows: when the valve body 2 and the flange sleeve 3 are being fixedly welded, the valve body 2 and the flange sleeve 3 are inserted and sleeved on one end of the positioning sleeve 10. At this time, the No. 1 motor 9 is started, so that the No. 1 motor 9 can drive the pushing column 11 to move horizontally through the threaded column 12, that is, drive the pushing cone 15 to squeeze the extrusion seat 16 uniformly distributed around the outside, so that the extrusion seat 16 can drive the external stretching frame 17 to stretch, prompting the stretching frame 17 to uniformly squeeze the inner wall of the valve body 2 and the flange sleeve 3, so that the valve body 2 and the flange sleeve 3 can be quickly concentric with the positioning sleeve 10, that is, the effect of rapid concentricity of the valve body 2 and the flange sleeve 3 is achieved, and then the valve body 2 and the flange sleeve 3 are quickly fixed concentrically, thereby achieving the effect of rapid concentricity of the valve body 2 and the flange sleeve 3. The positioning and fixing efficiency of the valve is greatly improved, that is, the welding processing efficiency of the valve is improved. When the valve body 2 and the flange sleeve 3 are annularly welded, the rotary table 8 is rotated so that the rotary table 8 can drive the valve body 2 to rotate through the positioning sleeve 10, so that the valve body 2 can drive the welding part to rub against the wire brush 183, so that the virtual welding slag at the welding part can be quickly removed, thereby making it convenient for the staff to observe the weld when the valve body 2 is welded, avoiding the need to wait for the valve body 2 to be welded and cooled before manual inspection, which is a time-consuming problem. Therefore, the convenience of valve welding inspection is improved. When the valve welding is completed, the No. 1 motor 9 is started so that the No. 1 motor 9 can drive the push column 11 to move horizontally in the opposite direction through the threaded column 12. When the positioning sleeve 10 is rotated, the stretching frame 17 is driven to rotate, so that the stretching frame 17 is driven to rotate directly above the positioning sleeve 10, thereby causing the stretching frame 17 to fall freely. As a result, the magnet plate 21 is driven to drive the stretching frame 17 to be adsorbed and fixed inside the positioning sleeve 10, thereby achieving the storage and fixing effect of the stretching frame 17, thereby facilitating multiple fixations of the valve. When the valve body 2 is fixed, the electric slide rail 4 is started, so that the electric slide rail 4 drives the sliding table 6 to move horizontally through the sliding seat 5, that is, the valve body 2 is driven to move horizontally through the positioning sleeve 10, thereby achieving the effect of adjusting the welding position of the valve body 2. When the valve body 2 needs to be welded, the sliding table is moved horizontally. 6, so that the sliding platform 6 can drive the valve body 2 to move horizontally to the inside of the protective cover 22 through the positioning sleeve 10, so that the protective cover 22 can seal the outside of the valve body 2, thereby avoiding the problem of workers being injured when high-temperature metal debris splashes during the welding of the valve body 2, thereby improving the safety of the valve welding. When the No. 1 motor 9 drives the push column 11 to move horizontally through the threaded column 12, the limit bar 23 can limit the horizontally moving push column 11, thereby avoiding the problem of deflection when the threaded column 12 drives the push column 11 to move, thereby achieving the limiting effect of the push column 11 when it moves horizontally, that is, improving the stability of the push cone 15 when it moves horizontally. When performing annular welding of the valve body 2, start the No. 2 motor 192,The second motor 192 is able to drive the worm gear 191 to rotate slowly through the worm 193, that is, to drive the rotary table 8 to rotate slowly, so that the rotary table 8 can drive the valve body 2 to rotate slowly through the positioning sleeve 10, thereby achieving the rotation effect of the valve body 2 during welding, thereby bringing convenience to the annular welding of the valve. When the valve is welded, the industrial vacuum cleaner 202 is started, so that the industrial vacuum cleaner 202 can absorb the air inside the protective cover 22 through the storage barrel 201, so that the metal debris inside the protective cover 22 can enter the storage barrel 201 along with the air, thereby achieving the effect of collecting welding debris, avoiding the problem of welding debris falling into the interior of the welding device and being difficult to clean, thereby improving the cleanliness of the interior of the welding device. When absorbing welding exhaust gas, the filter cover 24 can absorb and filter nitrogen oxides in the exhaust gas, thereby avoiding the problem of nitrogen oxides being directly discharged into the air during exhaust gas emission, causing pollution of the air around the welding device, thereby improving the cleanliness of the valve welding.

[0044] It should be noted that the present invention is not limited to the specific structures shown in the drawings in the above embodiments, and various changes can be made thereto within the scope of knowledge possessed by ordinary technicians in this field.
