[0027] like Figures 1 to 4 As shown, the present invention provides a positioning welding auxiliary fixture, including a base plate 1, a fixed support assembly 2, an adjustable support assembly 3 and a clamping assembly 4.

[0028] The fixed support assembly 2 includes a fixed plate 201 fixedly arranged at one end of the bottom plate 1, a magnetic plate 202 is installed on the inner side of the fixed plate 201, the magnetic positioning sleeve 203 can be adsorbed and installed on the magnetic plate 202, and a side pipe sleeve 20 is nested in the magnetic positioning sleeve 203;

[0029] The adjustment support assembly 3 includes a sliding plate 301 slidably mounted on the other end of the bottom plate 1 and a rotating plate 302 hingedly mounted on the far end of the sliding plate 301. A second magnetic plate 303 is mounted on the inner side of the rotating plate 302. The second magnetic positioning sleeve 304 can be adsorbed and mounted on the second magnetic plate 303. Another sleeve 20 is nested in the second magnetic positioning sleeve 304. The rotation angle of the rotating plate 302 can be adjusted by an angle adjustment mechanism. Specifically:

[0030] The angle adjustment mechanism includes a support rod 1 308 hingedly installed in the middle of the rotating plate 302, and a support rod 2 309 hingedly installed in the lower section of the rotating plate 302, a connecting rod 310 arranged parallel to the rotating plate 302 is hingedly installed between the support rod 1 308 and the support rod 2 309, a sliding support block 306 is installed on the hinge axis of the support rod 2 309 and the connecting rod 310, a sliding support plate 307 is hingedly installed at the end of the support rod 1 308, and the sliding support block 306 and the sliding support plate 307 are slidably arranged on the slide rail 305 of the base plate 1.

[0031] The sliding support plate 307 can be locked with the bottom plate 1 by a locking member. The locking member includes a plurality of positioning holes 1 311 arranged in parallel on a positioning plate on one side of the bottom plate 1, and a positioning hole 2 312 is provided on the side wall of the sliding support plate 307, wherein one of the positioning holes 1 311 and the positioning hole 2 312 are connected by a positioning pin 313.

[0032] The clamping assembly 4 includes a sliding box 402 slidably mounted on the base plate 1 , a guide groove 401 is provided on the base plate 1 , the sliding box 402 is slidably arranged on the guide groove 401 , and the guide groove 401 is arranged parallel to the sliding direction of the sliding plate 301 .

[0033] Two clamping plates 405 with adjustable spacing are slidably mounted on the sliding box 402, and the clamping plates 405 are used to clamp on both sides of the pipe 30. Specifically:

[0034] A bidirectional lead screw 403 is arranged on the sliding box 402 perpendicular to the sliding direction of the sliding plate 301. One end of the bidirectional lead screw 403 is driven to rotate by a turntable 406. The two clamping plates 405 are respectively mounted on two screws of different rotation directions of the bidirectional lead screw 403 through lead screw nuts (not shown in the figure). The moving directions of the two clamping plates 405 are limited by the slide grooves set on the sliding box 402.

[0035] Two sets of mutually parallel limiting plates 404 are arranged opposite to the two clamping plates 405 .

[0036] The working principle of the device of the present invention is:

[0037] First, the two pipe sleeves 20 are respectively sleeved on the corresponding magnetic positioning sleeve 1 203 and magnetic positioning sleeve 2 304 , and the two pipe sleeves 20 are sleeved on both sides of the pipe 30 .

[0038] After that, one side of the magnetic positioning sleeve 1 203 is adsorbed on the magnetic plate 1 202, and the position of the sliding plate 301 is adjusted horizontally along the bottom plate 1, and then the rotating plate 302 is rotated so that one end of the magnetic positioning sleeve 2 30 can be adsorbed on the rotating plate 302 where the magnetic plate 2 303 is located. At this time, the rotating turntable 406 is rotated, and the clamping plates 405 with different rotation directions mounted on the bidirectional lead screw 403 will move toward each other, and the two sets of limit plates 404 connected thereto will clamp on both sides of the pipe fitting 30, so that the pipe fitting 30 and the pipe sleeves 20 at both ends are located on the same vertical plane. In this process, the magnetic positioning sleeve 2 304 and the magnetic positioning sleeve 1 203 can be displaced in a small range relative to their respective magnetic plates.

[0039] Finally, the sliding support plate 307 is pressed inwardly so that the support rod 1 308 and the support rod 2 309 are supported on the middle and bottom of the rotating plate 302 respectively, and the position of the sliding support plate 307 relative to the bottom plate 1 is locked with the positioning pin 313 .

[0040] The device of the present invention can achieve preliminary pre-support of the pipe fitting 30 and the pipe sleeves 20 on both sides by fixing the support component 2 and adjusting the cooperation between the support components 3, and then further achieve clamping of the pipe fitting 30 between the pipe sleeves 20 through the clamping component 4. Since the relative angle between the pipe sleeves 20 is fixed, the pipe fitting 30 will not be easily twisted during the clamping process, thereby achieving pre-clamping of the pipe fitting 30 and the pipe sleeves 20 at both ends. Finally, the relative position between the welded parts is locked by the angle adjustment mechanism. The device provides a welding fixture that is suitable for welded parts with different angles of pipe sleeves and different bending directions of pipe fittings, thereby improving the welding quality and processing efficiency of the product.

[0041] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
