[0019] See Figure 1-4 This utility model relates to an automatic straight seam welding trolley for pipes, including a linear guide rail 1, a rack 2, a mounting base 3, a control box 4, a power battery 5, a drive motor 6, a bracket 7, and a welding torch adjustment assembly. A slide block 8 is slidably mounted on the linear guide rail 1, and the mounting base 3 is mounted on the slide block 8. The rack 2 is disposed on the side of the linear guide rail 1. The linear guide rail 1 is fixed to a base plate 9, and the rack 2 is connected to the side of the base plate 9 by screws. Multiple magnetic switches 10 are spaced apart at the bottom of the base plate 9. The magnetic switches 10 are used to magnetically attach the device to the workpiece to be welded. The mounting base 3 is Z-shaped and includes a horizontal top mounting section, a horizontal bottom mounting section, and a vertical mounting section. The horizontal top mounting section of the mounting base 3 is fixedly equipped with the control box 4 and the power battery 5. The power battery 5 provides power. The control box 4 centrally houses the electrical buttons for convenient operation. The horizontal bottom mounting part of the mounting base 3 is hinged to the clutch plate 11, the vertical mounting part of the mounting base 3 is connected to the bracket 7, the bracket 7 is connected to the welding torch adjustment assembly, the welding torch adjustment assembly is connected to the welding torch chuck 12, the welding torch chuck 12 is used to hold the welding torch, the bracket 7 is inverted T-shaped, and the top of the bracket 7 is also equipped with a push-pull handle 13.

[0020] The clutch plate 11 is connected to the motor base 14, and the drive motor 6 is fixed on the motor base 14. The output gear shaft 6.1 of the drive motor 6 is adapted to the rack 2. The drive motor 6 is provided with a motor cover 15, which covers the hinge between the clutch plate 11 and the mounting base and protects the hinge and the drive motor. The clutch plate 11 is provided with a locking pin 16. The horizontal bottom mounting part of the mounting base 3 is provided with a hole corresponding to the locking pin 16. The locking pin 16 can move to insert or withdraw into the horizontal bottom mounting part of the mounting base to lock or loosen the mounting base 3. The locking pin 16 is a knob plunger self-locking spring positioning pin. When the locking pin 16 is locked, the output end of the drive motor 6... The output gear shaft 6.1 meshes with the rack 2. The drive motor 6 drives the output gear shaft 6.1 to move linearly along the rack 2, which in turn drives the mounting base 3, bracket 7, welding torch adjustment assembly, and welding torch chuck 12 to move linearly along the linear guide rail 1, realizing the automatic linear movement of the trolley and thus achieving automatic welding of the straight seam of the pipe. When the locking pin 16 is released, the clutch plate 11 rotates around the hinge point, causing the motor base 14, drive motor 6, and its output gear shaft 6.1 to swing, thereby disengaging the output gear shaft 6.1 from the rack 2. The push-pull handle 13 pushes the trolley horizontally, and under the sliding action of the slide 8 and the linear guide rail 1, the trolley moves quickly to the designated position (welding position). The clutch plate 11 has a first limiting screw 17 and a second limiting screw 18 on both sides of the swing direction. The first limiting screw 17 is set in the vertical mounting part of the mounting base 3, and the second limiting screw 18 is set in the horizontal bottom mounting part of the mounting base 3. Installing the drive motor and control box separately facilitates heat dissipation for each component and extends the service life of the welding carriage.

[0021] The welding torch adjustment assembly includes a swing arm 19, a cross slide base 20, a cross slide 21, and a welding torch angle adjuster 22. The swing arm 19 is hinged to one bottom end of the bracket 7 and is locked by a locking wrench 23. The bottom end of the bracket 7 on this side has an arc-shaped groove corresponding to the locking wrench 23. The swing arm 19 is connected to the cross slide base 20, which is used to fix the cross slide 21. The cross slide 21 is connected to the welding torch angle adjuster 22, which is connected to the welding torch chuck 12. The cross slide 21 adjusts the left-right and up-down positions of the welding torch. Under the combined action of the swing arm 19 and the cross slide 21, the welding torch can be adjusted in all directions. A welding torch angle adjuster 22 is provided for fine-tuning the welding torch angle and can be selected according to actual welding needs.

[0022] The welding torch chuck 12 and the rack 2 are arranged on both sides of the linear guide rail 1 to balance the trolley. In order to prevent sparks from splashing, a baffle 24 is also provided between the linear guide rail 1 and the welding torch chuck 12. The baffle 24 is fixed on the bracket 7.

[0023] The bracket 7 is also connected to the welding torch auxiliary bracket 25, which is used for the installation of the pipe clamp 26 to fix the body of the welding torch.

[0024] The linear guide rail 1 has anti-detachment limiters 27 at both ends along its length. When the trolley moves to the anti-detachment limiter 27, the corresponding rack has a notch, so that the output gear shaft of the drive motor can rotate freely at the anti-detachment limiter to ensure safety.

[0025] Operating instructions: Place the linear guide rail with the magnetic switch installed on the surface of the workpiece to be welded, and turn on the magnetic switch to make the linear guide rail firmly set on the workpiece. Loosen the locking pin 16, and the output gear shaft 6.1 disengages from the rack 2. The trolley is pushed horizontally by the push-pull handle 13. Under the sliding action of the slide block 8 and the linear guide rail 1, the trolley moves quickly and moves to the welding start position. The position of the welding gun is adjusted so that the welding gun is aimed at the gap of the pipe. Tighten the locking pin, and the output gear shaft 6.1 of the drive motor 6 meshes with the rack 2. Press the start switch, and the drive motor 6 drives the output gear shaft 6.1 to move linearly along the rack 2, which in turn drives the mounting base 3, bracket 7, welding torch adjustment assembly and welding torch chuck 12 to move linearly along the linear guide rail 1, thereby realizing the automatic linear movement of the trolley and thus realizing the automatic welding of the straight seam of the pipe.

[0026] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
