[0028] As Figures 1-4 shown, the present application provides a welding fixture with adjustable spacing, including a clamping structure 1 and an adjusting structure 2. The clamping structure 1 includes two groups of columns 101. Two cross plates 102 are installed on the opposite surfaces of the two groups of columns 101. An installation column 104 is fixedly connected to the opposite surfaces of the four cross plates 102. A clamping jaw 105 is fixedly connected to the opposite surfaces of the two installation columns 104. The adjusting structure 2 includes a base 201. The adjusting structure 2 includes a base 201. Two sliders 202 are arranged inside the base 201. A bidirectional lead screw 204 is threadedly connected to the middle of the two sliders 202.

[0029] The clamping jaw 105 includes a locking block 1051. A mating block 1052 is provided at the top of the locking block 1051. A threaded rod 1053 is threadedly connected to the middle of the mating block 1052. The bottom of the threaded rod 1053 is rotatably connected to the locking block 1051. Two clamping jaws 1055 are movably connected to both sides of the mating block 1052.

[0030] Locking blocks 1054 are fixedly connected to the ends of the two clamping jaws 1055 and the bottom of the locking block 1051.

[0031] Chutes 1058 penetrating the clamping jaws 1055 are provided at the front parts of the two clamping jaws 1055. Positioning pins 1057 are connected to both sides of the locking block 1051. The two positioning pins 1057 are slidably connected in the chutes 1058.

[0032] A rotating pin 1056 is arranged at the connection position between the clamping jaw 1055 and the mating block 1052. The rotating pin 1056 penetrates the chute 1058 and the mating block 1052.

[0033] A chute adapted to the column 101 is provided at the top of the base 201.

[0034] In the middle of the two sliders 202, a bidirectional lead screw 204 is provided, and one end of the bidirectional lead screw 204 extends out of the base 201 and is connected to a runner 205.

[0035] On both sides of the two sliders 202, guide rods 203 connected to the base 201 are provided, and the sliders 202 are slidably connected to the guide rods 203.

[0036] The threaded rod 1053 is threadedly connected to the locking block 1051

[0037] Working principle:

[0038] Before using the device, first check each component of the device to ensure that each component of the device fits properly and that the device can work properly.

[0039] When the user needs to fix the pipe, insert the welding ends of the two pipes into the two clamping claws 105 so that the welding ends of the two pipes correspond to each other. Adjust the threaded rod 1053 according to the size of the pipe. The rotation of the threaded rod 1053 drives the locking block 1051 to rise. The rising of the locking block 1051 drives the two positioning pins 1057 to slide in the chute 1058, so that the two clamping jaws 1055 rotate around the rotating pin 1056 in the mating block 1052, realizing the expansion of the two clamping jaws 1055. After the pipe is inserted, rotate the threaded rod 1053 in the reverse direction to lock the pipe.

[0040] After the pipe is locked, rotate the runner 205 to cause the runner 205 to drive the bidirectional lead screw 204 to rotate. The rotation of the bidirectional lead screw 204 drives the respective sliders 202 to approach each other. The mutual approach of the two sliders 202 drives the clamping structure 1 connected to the sliders 202 to approach each other. When the pipes fixed on the clamping structure 1 are butted, stop rotating the runner 205, and the staff performs welding operations on it.

[0041] By providing the clamping structure 1, the device can fix pipes with different diameters, making the application range of the device wider. At the same time, by providing the adjustment structure 2, the device can perform adaptive adjustment, avoiding problems in the operation of welding personnel due to fixed positions.
