[0002] Valves and pipe fittings include valves and pipe fittings, which are both used in pipeline connections or control systems. Valves and pipe fittings cannot exist independently, but complement each other. The welding process in the manufacture of valves and pipe fittings is a key process link, which ensures the sealing performance and structural integrity of the valve. By selecting appropriate welding methods, materials and processes, and strictly controlling the welding quality, the sealing performance and structural integrity of the valve can be ensured to meet the needs of various industrial applications.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown, the present invention provides a welding device for manufacturing valve pipe fittings, including a main body support 100 and a welding gun 200, and also includes:

[0034] A positioning component 300, the positioning component 300 is arranged inside the main frame 100;

[0035] A supporting component 400, the supporting component 400 is mounted on the upper end of the main support 100, and the supporting component 400 and the positioning component 300 are in the same vertical plane;

[0036] The positioning component 300 includes a support base 301 rotatably connected to the main support 100, a first telescopic rod 304 is fixedly connected inside the support base 301, a limited extrusion rod 305 is fixedly connected to the output end of the first telescopic rod 304, a first limiting rod 306 is fixedly connected to the top of the support base 301, a limited sliding groove 307 is provided inside the first limiting rod 306, and a positioning extrusion block 308 is slidably connected inside the limiting sliding groove 307;

[0037] The supporting component 400 includes a second telescopic rod 401 and a supporting frame 403 fixedly connected to the main frame 100 . The output end of the second telescopic rod 401 is fixedly connected to a sliding frame 404 . The middle and lower ends of the sliding frame 404 are provided with a fork-shaped supporting block 406 .

[0038] The above solution is adopted: the bottom of the valve body 500 is pressed against the fork-shaped support block 406 located at the lower side, so that the valve body 500 can be placed between a pair of fork-shaped support blocks 406, and then the valve body 500 is released, and the valve body 500 is driven by the spring 405 to move upward, and the second limit rod 402 is inserted into the top of the valve body 500, and then the pipe body 600 is sleeved on the first limit rod 306 and placed on the top of the support base 301, and the pipe body 600 and the valve body 500 are quickly placed;

[0039] The second telescopic rod 401 pushes the sliding bracket 404 to move downward along the support frame 403 until the valve body 500 conflicts with the pipe body 600, and then the first telescopic rod 304 is started, and the limiting extrusion rod 305 is pushed to slide upward by the first telescopic rod 304, so that the limiting extrusion rod 305 squeezes the positioning extrusion block 308 to expand around, so that the positioning extrusion block 308 conflicts with the pipe body 600 and the valve body 500, and squeezes the pipe body 600 and the valve body 500 to move until all the positioning extrusion blocks 308 conflict with the valve body 500 and the pipe body 600, thereby completing the positioning and fixing of the pipe body 600 and the valve body 500, and then the driving assembly 302 can drive the support base 301 through the transmission gear 303 to drive the valve body 500 and the pipe body 600 to rotate, and the welding gun 200 performs welding.

[0040] like Figures 2 to 5 As shown, the positioning component 300 also includes a driving assembly 302 fixedly connected to the inside of the main bracket 100, and a transmission gear 303 is fixedly connected to the middle of the support base 301. The driving assembly 302 is used to drive the transmission gear 303 to rotate. The limiting extrusion rod 305 is slidably connected to the inside of the first limiting rod 306. The positioning extrusion block 308 is in conflict with the limiting extrusion rod 305. The inner and outer sides of the bottom of the positioning extrusion block 308 are provided with inclined surfaces. The top of the limiting extrusion rod 305 is in an arc shape and conflicts with the inner inclined surface of the positioning extrusion block 308.

[0041] The above scheme is adopted: by setting a driving component 302 and a transmission gear 303, the driving component 302 drives the transmission gear 303 to rotate, so that the transmission gear 303 drives the support base 301 to rotate, and the support base 301 drives the pipe body 600 and the valve body 500 to rotate, so as to weld them, and by setting a limiting extrusion rod 305 and a positioning extrusion block 308, the limiting extrusion rod 305 extrude the positioning extrusion block 308 to expand, and by providing inclined surfaces at the top of the limiting extrusion rod 305 and the inner bottom of the positioning extrusion block 308, it is convenient for the limiting extrusion rod 305 to push and extrude the positioning extrusion block 308 to expand.

[0042] like Figures 2 to 6As shown, a sloped protrusion block 309 is provided inside the first limiting rod 306 , and the sloped protrusion block 309 is distributed in a ring shape inside the first limiting rod 306 and corresponds to the position of the positioning extrusion block 308 . The sloped protrusion block 309 is inclined downward toward the first telescopic rod 304 , and the sloped protrusion block 309 conflicts with the positioning extrusion block 308 .

[0043] The above scheme is adopted: the design of the inclined surface protrusion block 309 can facilitate the expansion and closing of the positioning extrusion block 308. By setting the inclined surface protrusion block 309 to be inclined downward toward the first telescopic rod 304, the positioning extrusion block 308 can move and expand along the inclined surface protrusion block 309 when being squeezed by the limiting extrusion rod 305. At the same time, after the limiting extrusion rod 305 releases the squeezing of the positioning extrusion block 308, the positioning extrusion block 308 loses support and will move downward along the inclined surface protrusion block 309 under the action of gravity, and then close to release the interference with the valve body 500 and the pipe body 600, and quickly release the fixation of the pipe body 600 and the valve body 500.

[0044] like Figures 6 to 8 As shown, the second limiting rod 402 is rotatably connected to the top of the inner side of the sliding bracket 404, the sliding bracket 404 is slidably connected to the support frame 403, the bottom of the sliding bracket 404 is fixedly connected to the spring 405, the fork-shaped support block 406 is fixedly connected to the sliding bracket 404 and the spring 405 respectively, the bottom of the second limiting rod 402 is in contact with the valve body 500, the valve body 500 is in contact with the fork-shaped support block 406, and when the valve body 500 is placed between a pair of fork-shaped support blocks 406, the spring 405 is squeezed to expand, and then the top of the valve body 500 is inserted by the second limiting rod 402, and then the spring 405 contracts, pushing the valve body 500 to rise and contact the second limiting rod 402.

[0045] The above scheme is adopted: by setting the support component 400, the second telescopic rod 401 drives the sliding bracket 404 to move up and down, so that the fork-shaped support block 406 drives the valve body 500 to move synchronously, so that the valve body 500 conflicts with the pipe body 600, and at the same time, the first limit rod 306 is inserted into the valve body 500. The setting of the second limit rod 402 enables the valve body 500 to rotate synchronously with the support base 301. The setting of the spring 405 enables the fork-shaped support block 406 at the bottom to be temporarily squeezed and moved downward when the valve body 500 is placed. After the second limit rod 402 is inserted into the top of the valve body 500, the spring 405 can contract to make a pair of fork-shaped support blocks 406 clamp and support the valve body 500, so that the valve body 500 remains stable.

[0046] like Figure 2 , Figure 4 , Figure 5 and Figure 7As shown, a pipe body 600 is placed on the top of the support base 301, and the pipe body 600 is sleeved on the outside of the first limiting rod 306. The pipe body 600 conflicts with the positioning extrusion block 308. The pipe body 600 is located at the bottom of the valve body 500, and the bottom of the valve body 500 is on the same vertical line as the first limiting rod 306. The valve body 500 is driven downward by the fork-shaped support block 406, so that the valve body 500 conflicts with the pipe body 600, and at the same time, the first limiting rod 306 is inserted into the valve body 500.

[0047] By adopting the above scheme: by setting the first limiting rod 306, the pipe fitting body 600 can be placed conveniently and quickly. At the same time, the positioning extrusion block 308 set inside the first limiting rod 306 can quickly position the valve body 500 and the pipe fitting body 600, so that the valve body 500 and the pipe fitting body 600 are aligned and in a matching state, thereby completing the positioning conveniently and quickly and preparing for welding.

[0048] like Figures 2 to 8 As shown, the first telescopic rod 304 pushes the limiting extrusion rod 305 to slide upward, so that the limiting extrusion rod 305 squeezes the positioning extrusion block 308 to expand in all directions, and the positioning extrusion block 308 is in conflict with the pipe body 600 and the valve body 500, and the pipe body 600 and the valve body 500 are squeezed to move to a matching state. The welding gun 200 is fixedly connected to the lower side of the main bracket 100 and is located on the side of the support base 301. The gun head end of the welding gun 200 faces the contact point between the pipe body 600 and the valve body 500 at the top of the support base 301.

[0049] The above scheme is adopted: the limiting extrusion rod 305 is pushed to slide upward by the first telescopic rod 304, and the limiting extrusion rod 305 will first conflict with the bottom inclined surface of the positioning extrusion block 308, and then the limiting extrusion rod 305 squeezes the positioning extrusion block 308 to expand around, so that the positioning extrusion block 308 conflicts with the pipe fitting body 600 and the valve body 500, and squeezes the pipe fitting body 600 and the valve body 500 to move until the positioning extrusion block 308 conflicts with the valve body 500 and the pipe fitting body 600, thereby completing the positioning and fixing of the pipe fitting body 600 and the valve body 500, and then the driving assembly 302 can drive the support base 301 through the transmission gear 303 to drive the valve body 500 and the pipe fitting body 600 to rotate, and the welding gun 200 welds them at the same time.

[0050] The working principle and use process of the present invention are as follows: when in use, firstly, the pipe fitting body 600 is sleeved on the first limiting rod 306 and placed on the top of the support base 301, and then the bottom of the valve body 500 is pressed against the fork-shaped support block 406 located at the lower side, so that the valve body 500 can be placed in the middle of a pair of fork-shaped support blocks 406, and then the valve body 500 is released, and the valve body 500 is driven by the spring 405 to move upward, and the second limiting rod 402 is inserted into the top of the valve body 500, so as to complete the placement of the pipe fitting body 600 and the valve body 500;

[0051] The second telescopic rod 401 pushes the sliding bracket 404 to move downward along the support frame 403 until the valve body 500 conflicts with the pipe body 600, and then the first telescopic rod 304 is started, and the limiting extrusion rod 305 is pushed to slide upward by the first telescopic rod 304, so that the limiting extrusion rod 305 squeezes the positioning extrusion block 308 to expand around, so that the positioning extrusion block 308 conflicts with the pipe body 600 and the valve body 500, and squeezes the pipe body 600 and the valve body 500 to move until all the positioning extrusion blocks 308 conflict with the valve body 500 and the pipe body 600, thereby completing the positioning and fixing of the pipe body 600 and the valve body 500, and then the driving assembly 302 can drive the support base 301 through the transmission gear 303 to drive the valve body 500 and the pipe body 600 to rotate, and the welding gun 200 performs welding.
