[0031] An angle adjustment mechanism 50 is provided on the platform plate 10. The angle adjustment mechanism 50 includes an adjustment gear 51 connected to one end of the moving slide rail 30, a hollow fixed block 52 installed on one side of the adjustment gear 51, a movable shaft 53 passing through the fixed block 52, a tooth block 54 connected to the movable shaft 53 near one end of the adjustment gear 51, a spring 56 sleeved on the movable shaft 53, a limiting ring 57 located on the movable shaft 53 near the tooth block 54, and a pull button 55 on the movable shaft 53 on the opposite side of the tooth block 54; the adjustment gear 51 is rotatably connected to the platform plate 10.

[0032] Specifically, please refer to the appendix Figure 1 In addition, mounting plates 70 are provided on both sides of the platform plate 10, and strip-shaped slot holes are provided on the mounting plates 70.

[0033] It should be noted that in this embodiment, by installing positioning pins in the strip-shaped slot holes of the mounting plates 70, the fixed installation of the device on the tabletop can be realized to ensure stability.

[0034] Specifically, please refer to the appendix Figure 2 and the appendix Figure 5 It can be seen that the vertical cross-sections of the fixed slide rail 20 and the moving slide rail 30 are both T-shaped structures, and a sliding block 41 adapted to the slide rail is provided at the bottom of the positioning block 40.

[0035] It should be noted that in this embodiment, the T-shaped fixed slide rail 20 and the moving slide rail 30 can make the sliding block 41 slide more stably on the slide rail.

[0036] Specifically, please refer to the appendix Figure 5 On the side of the sliding block 41, a positioning bolt 43 is installed, and the end of the positioning bolt 43 is in contact with the slide rail.

[0037] It should be noted that in this embodiment, by loosening the positioning bolt 43, the sliding block 41 can be slid on the slide rail, thereby adjusting the position of the positioning block 40, and by tightening the positioning bolt 43, the position of the positioning block 40 can be fixed, which is convenient for the butt joint of the welding part of the automobile pipe fitting.

[0038] Specifically, please refer to the appendix Figure 5 A chute 42 is provided on the positioning block 40. The positioning assembly 60 includes a fixed clamping plate 61 installed on one side of the top of the positioning block 40, a lead screw 63 rotatably connected in the chute 42, a moving clamping plate 62 slidably connected to the lead screw 63 through a nut, and a turning knob 64 connected to the lead screw 63.

[0039] It should be noted that in this embodiment, by rotating the turning knob 64, the position of the moving clamping plate 62 can be adjusted, so as to adjust the distance between the fixed clamping plate 61 and the moving clamping plate 62, thereby fixing steel pipes of different thicknesses.

[0040] Specifically, please refer to the attached Figure 5 . Rubber pads 80 are provided on the mutually approaching surfaces of the fixed clamping plate 61 and the movable clamping plate 62.

[0041] It should be noted that in this embodiment, the rubber pads 80 can increase the frictional resistance, thereby stably clamping the automotive pipe fittings.

[0042] Specifically, please refer to the attached Figure 6 . One end of the rotary knob 64 is provided with a coupling shaft 65. One end of the coupling shaft 65 is sleeved inside the lead screw 63. The coupling shaft 65 and the lead screw 63 can slide relative to each other. A toothed disc 66 is fixedly connected to the side of the positioning block 40. The coupling shaft 65 passes through the center of the toothed disc 66. Tooth patterns adapted to each other are provided on the surface of the rotary knob 64 close to the toothed disc 66.

[0043] It should be noted that in this embodiment, when it is necessary to adjust the distance between the fixed clamping plate 61 and the movable clamping plate 62, the rotary knob 64 can be pulled outwards to separate the tooth pattern on the rotary knob 64 from the toothed disc 66. Then the rotary knob 64 is rotated for adjustment. After the adjustment is completed, the rotary knob 64 is pushed inwards to engage the tooth pattern on the rotary knob 64 with the toothed disc 66, thereby fixing the rotary knob 64 and completing the locking to prevent the fixed clamping plate 61 and the movable clamping plate 62 from being unable to stably clamp the automotive steel pipe all the time.

[0044] Specifically, please refer to the attached Figure 6 . Anti-slip stripes are provided on the side surface of the rotary knob 64.

[0045] Specifically, please refer to the attached Figure 4 . Anti-slip stripes are provided on the pull knob 55.

[0046] It should be noted that in this embodiment, the anti-slip stripes can increase the frictional resistance, thereby rotating and pulling the rotary knob 64 and the pull knob 55 more effectively.

[0047] Specifically, please refer to the attached Figure 1 and the attached Figure 3 . A secondary block 31 is installed at one end of the movable slide rail 30 away from the adjustment gear 51. A pulley 32 is rotatably connected to the bottom of the secondary block 31.

[0048] It should be noted that in this embodiment, when the movable slide rail 30 rotates around the adjustment gear 51, the pulley 32 contacts and slides on the platform plate 10, so that the movement of the movable slide rail 30 is smoother and the angle adjustment is more convenient to complete.

[0049] The specific operation method of the present invention is as follows:

[0050] First, place two automotive steel pipes on the two positioning blocks 40, and then adjust the distance and angle of the positioning blocks 40 according to the butt welding joint of the steel pipes.

[0051] Pull the knob 55 outward to withdraw the detent block 54 from the adjustment gear 51. Then, the movable slide rail 30 can be rotated to complete the angular change of the steel pipe on the movable slide rail 30. After the adjustment is completed, release the knob 55, and the limiting ring 57 is pushed by the force of the spring 56 to reset the detent block 54 and insert it into the adjustment gear 51 to complete the fixation of the movable slide rail 30.

[0052] Then loosen the positioning bolt 43, and the slider 41 can slide on the slide rail to adjust the position of the positioning block 40. Tighten the positioning bolt 43 to fix the position of the positioning block 40.

[0053] Finally, align the welding positions of the two steel pipes, then pull the knob 64 outward to separate the tooth pattern on the knob 64 from the gear disc 66. Then rotate the knob 64 for adjustment to adjust and fix the distance between the fixed clamping plate 61 and the movable clamping plate 62 to fix steel pipes of different thicknesses. After the adjustment is completed, push the knob 64 inward to engage the tooth pattern on the knob 64 with the gear disc 66.

[0054] Finally, welding can be carried out.

[0055] The present invention has been described exemplarily in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
