[0035] Please refer to Figures 1-5 As shown, a building welding surface pretreatment mechanism, the building welding surface pretreatment mechanism includes:

[0036] An automatic expansion component 1, a grinding part 2 is fixedly arranged on the automatic expansion component 1, and the automatic expansion component 1 can automatically expand when rotating;

[0037] A telescopic adjustment component 3, the telescopic adjustment component 3 is fixedly connected to the automatic expansion component 1, the telescopic adjustment component 3 can telescopically move, and the telescopic adjustment component 3 can drive the automatic expansion component 1 to rotate.

[0038] Through the above technical solution, in order to solve the problem in the prior art that when an ordinary grinding treatment device grinds the inner wall of a building metal pipe, it is difficult to deeply grind the inner wall of the pipe, this application designs the telescopic adjustment component 3 and the automatic expansion component 1. By the combined use of the telescopic adjustment component 3 and the automatic expansion component 1, it can be more convenient to extend into the interior of the pipe for rotary grinding, and at the same time, it can effectively automatically adapt to metal pipes with different apertures, and can make the grinding part 2 automatically fit the inner wall of the pipe during grinding, which is convenient for effectively grinding the inner wall of the metal pipe and solves the problem in the prior art that it is not convenient to grind the inner wall of the metal pipe.

[0039] The automatic expansion component 1 includes a circular shell 101, a first connecting shaft 102, an eccentric weight 103, a moving column 104 and a moving rod 107. A number of first connecting shafts 102 are fixedly arranged in the inner cavity of the circular shell 101, and an eccentric weight 103 is rotatably connected to each of the number of first connecting shafts 102. Through this technical solution, when the circular shell 101 rotates, the eccentric weight 103 can be driven to deflect by the action of centrifugal force.

[0040] A number of moving columns 104 are slidably arranged on the side wall of the circular shell 101, and the number of moving columns 104 corresponds to the number of eccentric weights 103 one by one, and one end of the moving column 104 contacts the eccentric weight 103. Through this technical solution, when the eccentric weight 103 deflects, the moving column 104 can be pushed to move outward by extrusion.

[0041] One end of the moving column 104 is fixedly connected with a circular plate 105. One end of a reset spring 106 is fixedly connected to the side wall of the circular plate 105, and the other end of the reset spring 106 is fixedly connected to the outer wall of the circular shell 101.

One end of a compression spring 108 is fixedly connected to the other end of the moving rod 107, and the other end of the compression spring 108 is fixedly connected to the inner cavity wall of the moving column 104. Through this technical solution, when the inner wall of a building metal pipe needs to be polished, the automatic expansion component 1 can be moved into the metal pipe. The rotation of the circular shell 101 can drive the grinding part 2 to rotate. At the same time, the eccentric weight 103 deflects, so that the moving column 104 moves. The movement of the moving column 104 can drive the moving rod 107 to move, thereby driving the grinding part 2 to move, so that the grinding part 2 automatically fits on the inner wall of the pipe, and the inner wall of the pipe is polished by the rotation of the grinding part 2, which can effectively adapt to pipes with different inner diameters within a certain range.

One end of the power rotating shaft 307 is fixedly connected to the automatic expansion component 1. Through this technical solution, the rotation of the power rotating shaft 307 can be driven by the operation of the power motor 306, thereby driving the automatic expansion component 1 to rotate. The movement of the automatic expansion component 1 can be driven by the telescopic movement of the telescopic cylinder 301 to adjust the position.

[0046] A fixed base 5 is fixedly connected to the bottom end of the support frame 4. A second connecting shaft 6 is rotatably connected to the top end of the support frame 4. An adjusting arm 7 is fixedly connected to the second connecting shaft 6. One end of the adjusting arm 7 is rotatably connected to a first connecting member 9.
