[0015] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there can be an intermediate element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time: Example

[0017] Reference Figure 1-Figure 6According to an embodiment of the utility model, a pipeline welding auxiliary clamp comprises two abutting welding pipes 10 and a circular ring 11, the inner circumference of the circular ring 11 is slidably connected with two sliding blocks 13, the sliding block 13 on the left side is connected with two front and rear symmetrical clamping blocks 14 through a fixed rod, the ends of the two clamping blocks 14 away from each other are fixed with a connecting frame 15, and the connecting frame 15 is threadedly connected with a threaded abutting rod 16, the two clamping blocks 14 are arranged in a V shape at an angle close to the end of the welding pipe 10, and a bidirectional screw 22 is rotatably connected to the sliding block 13 on the right side, and the outer circumference of the bidirectional screw 22 is provided with two front and rear thread grooves with opposite threads, and the front and rear ends of the two bidirectional screws 22 are threadedly connected with screws The threaded clamp block 24, the two threaded clamp blocks 24 are fixed with an extension slide 17 away from each other, and the two extension slides 17 are connected with a sliding plate 18 that can slide up and down, and the sliding plate 18 is threadedly connected with a locking screw 23, which extends to the end of the extension slide 17 and penetrates the sliding plate 18 to abut against the end surface of the extension slide 17, and the sliding plate 18 is elastic. The upper ends of the two sliding plates 18 are fixed with a fixed plate 19, and the two fixed plates 19 are slidably matched with a guide slide frame 20, and the fixed plate 19 is connected with a spring near the end of the guide slide frame 20, and the spring abuts against the guide slide frame 20, and the guide slide frame 20 is threadedly connected with a threaded rod 21, and a handle 12 is fixed in the ring 11;

[0018] When using, for example Figure 1 As shown, the welding pipe 10 is set vertically upward, and the user holds the handle 12 and moves the ring 11 closer, so that the clamping block 14 at the left end of the ring 11 abuts against the circumference of the welding pipe 10, and the V-shaped inclined surfaces of the front and rear clamping blocks 14 abut against the circumference of the welding pipe 10. The user rotates the threaded push rod 16 threadedly connected to the connecting frame 15 to rotate the threaded push rod 16 into the welding pipe 10 and approach it. The threaded push rod 16 abuts against the welding pipe 10 near the end of the welding pipe 10, and the welding pipe 10 is clamped by the threaded push rod 16 and the left and right clamping blocks 14 to complete the fixed connection. Then the user places the welding pipe 10 at the threaded clamping block 24. Similarly, the threaded rod 21 and the threaded guide frame 20 cooperate with each other, so that the threaded rod 21 and the threaded clamping block 24 clamp the circumference of the welding pipe 10, and by pushing the guide frame 20 part, the sliding block 13 rotates circumferentially in the ring 11, so that the welding pipe 10 is as shown in FIG. Figure 1 The lateral abutment welded pipe 10 is shown;

[0019] When the fitting position of two welding pipes 10 is not the set position, the user rotates the locking screw 23 to disengage the locking screw 23 from the abutment with the extension slide 17, and the sliding plate 18 can slide freely up and down at the extension slide 17. The user rotates the bidirectional screw 22 to make the bidirectional screw 22 drive the two threaded clamps 24 connected by threads to move forward and backward, and the two threaded clamps 24 approach each other or move away from each other, thereby changing the spacing between the two threaded clamps 24, so that the sliding plate 18 slides up and down, and adjusts the height position of the welding pipe 10 at the clamping end to adjust it to the corresponding set position for electric welding. By rotating the locking screw 23 in the opposite direction, the locking screw 23 is re-engaged with the welding pipe 10 for clamping to prevent the welding pipe 10 from sliding.
