Two connecting rods 42 are hinged on the hinge 41, and two cleaning plates 43 are slidably installed on the operating table 1. The two connecting rods 42 are hinged to the two cleaning plates 43 respectively. When the hydraulic cylinder 21 moves, the hydraulic cylinder 21 drives the hinge 41 to move to the left. When the hinge 41 moves to the left, it drives the two cleaning plates 43 to move away from each other through the two connecting rods 42. The two cleaning plates 43 clean the surface of the operating table 1 during movement.

[0030] A protective assembly 5 is provided on the operating table 1. The protective assembly 5 includes two mounting columns 51. A protective plate 52 is rotatably installed between the two mounting columns 51. Two telescopic rods 53 are installed on the operating table 1. The two telescopic rods 53 are slidingly connected to the protective plate 52. Two pull rods 54 are hinged on the two inner clamps 25 respectively. The two pull rods 54 are hinged to the protective plate 52. When the two inner clamps 25 move away from each other, the two inner clamps 25 drive the protective plate 52 to rotate downward through the two pull rods 54. The two mounting columns 51 and the two telescopic rods 53 support and fix the protective plate 52.

[0031] In this embodiment, the cleaning component 4 is provided so that the two cleaning plates 43 can clean the surface of the operating table 1 by moving themselves before and after the welding operation, so as to avoid the accumulation of a large amount of welding slag on the surface of the operating table 1 after long-term use. A large amount of welding slag is difficult to clean after agglomeration, which may affect subsequent welding operations; the protection component 5 is provided so that before the welding operation begins, the protection plate 52 can be rotated downward to partially protect the two front fork tubes. Since other parts have been installed on some of the front fork tubes, during the welding operation, the protection plate 52 can protect other parts and paint, so as to avoid sparks generated during the welding operation from splashing onto other parts and causing certain damage to the front fork assembly. When the welding operation is completed and the front fork assembly is disassembled, the protection plate 52 rises and resets without affecting subsequent operations.

[0032] The utility model relates to a welding jig for a front fork assembly of a children's electric scooter. When in use, the front fork assembly is mainly divided into two front fork tubes and a head tube, and an outer clamping block 24 and an inner clamping block 25 form a group. The staff places the two front fork tubes on a plurality of clamping plates 27 between the two groups of outer clamping blocks 24 and the inner clamping blocks 25. At this time, the staff can adjust the positions of the two outer clamping blocks 24 according to the specifications of the front fork assembly and rotate the ball screw 28. The ball screw 28 drives the two outer clamping blocks 24 to move in the opposite direction on the mounting seat 23 through the cooperation of the two threaded grooves and the balls. When the clamping plates 27 on the two outer clamping blocks 24 contact the two front fork tubes, the clamping plates 27 stop. The ball screw 28 is stopped and the hydraulic cylinder 21 is started. When the hydraulic cylinder 21 moves, it drives the curved slider 22 to move to the left. During the movement of the curved slider 22 to the left, it contacts the two interference rods 26 and drives the two interference rods 26 to move away from each other. The two interference rods 26 respectively drive the two inner clamping blocks 25 to move away from each other. The two inner clamping blocks 25 respectively drive the four clamping plates 27 to move towards the two front fork tubes until the four clamping plates 27 hold the two front fork tubes. At this time, the eight clamping plates 27 apply pressure to the two front fork tubes at the same time to complete the clamping of the two front fork tubes. The staff places the head tube on the base 36 in advance. When the hydraulic cylinder 21 moves, the fork frame 31 moves to the left. During the movement of the fork frame 31 to the left, it contacts the two connecting slide bars 32 and drives the two connecting slide bars 32 to move in the direction of approaching each other. The two connecting slide bars 32 respectively drive the two mounting blocks 33 to move in the direction of approaching each other. The two mounting blocks 33 respectively drive the two clamping blocks 35 to move in the direction of approaching the head tube through the two spring pieces 34 until the two clamping blocks 35 clamp the head tube stably. Through the setting of the front fork tube clamping assembly 2, the staff can adjust the position of the two outer clamping blocks 24 through the ball screw 28 to adapt to front fork tubes of different specifications and models. , and then through the cooperation of the two inner clamping blocks 25, the eight clamping plates 27 clamp the two front fork tubes stably, and through the cooperation of the eight clamping plates 27 and multiple springs, the eight clamping plates 27 can adapt to the outer wall shapes of different front fork tubes and can provide a certain shock absorption effect, thereby improving the clamping applicability of front fork tubes of various models and specifications; through the setting of the head tube clamping assembly 3, the two clamping blocks 35 can clamp the head tube while the two inner clamping blocks 25 move, and through the setting of the two spring pieces 34, the two clamping blocks 35 can effectively clamp head tubes of various different diameters, thereby improving the work efficiency of the clamping and fixing operation.

[0033] When the hydraulic cylinder 21 moves, the hydraulic cylinder 21 drives the hinge 41 to move to the left. When the hinge 41 moves to the left, the two cleaning plates 43 are driven to move away from each other through the two connecting rods 42. The two cleaning plates 43 clean the surface of the operating table 1 during movement. By setting the cleaning component 4, the two cleaning plates 43 can clean the surface of the operating table 1 by their own movement before and after the welding operation, so as to avoid the accumulation of more welding slag on the surface of the operating table 1 after long-term use. More welding slag is difficult to clean after agglomeration, which may affect subsequent welding operations. When the two inner clamping blocks 25 move away from each other, the two inner clamping blocks 25 respectively drive the protective plates through the two pull rods 54. 52 rotates downward, and the two mounting columns 51 and the two telescopic rods 53 support and fix the protective plate 52. When the two inner clamping blocks 25 are reset, the two inner clamping blocks 25 drive the protective plate 52 to reset through the two pull rods 54. Through the setting of the protective component 5, before the welding operation begins, the protective plate 52 can be rotated downward to partially protect the two front fork tubes. Since other parts have been installed on some front fork tubes, during the welding operation, the protective plate 52 can protect other parts and paint to prevent sparks generated during the welding operation from splashing onto other parts and causing certain damage to the front fork assembly. When the welding operation is completed, when the front fork assembly is disassembled, the protective plate 52 rises and resets without affecting subsequent operations.
