A plurality of first fixing grooves 5 are opened at the top end of the positioning table 1 and on both sides of the adjusting seat 9. Four positioning pins 6 are threadedly connected inside any four first fixing grooves 5. The four positioning pins 6 are symmetrically arranged. A plurality of second fixing grooves 11 are opened at the top end of the lifting plate 10. Two positioning seats 12 are threadedly connected inside any two second fixing grooves 11. The two positioning seats 12 are symmetrically arranged. By providing the square through holes 2, the positioning and guiding of the positioning plates 4 can be realized.

[0023] As Figure 3 and Figure 4 shown in the figure, a second bidirectional lead screw 13 is rotatably connected inside the adjusting seat 9. Two driven blocks 14 are engaged with the outer surface of the second bidirectional lead screw 13. A connecting rod 15 is rotatably connected to the top end of each of the two driven blocks 14. The other ends of the two connecting rods 15 are rotatably connected to the bottom end of the lifting plate 10. By providing the connecting rods 15, the lifting plate 10 can be lifted during the movement of the driven blocks 14, realizing the adjustment of the position of the connecting plate 24.

[0024] As Figure 4 shown in the figure, one end of the second bidirectional lead screw 13 penetrates through one side wall inside the adjusting seat 9 and is fixedly connected with a polygonal connecting column 18. A movable sleeve 19 is slidably connected to the outer surface of the polygonal connecting column 18. A fixed seat 17 is fixedly connected to one side of the adjusting seat 9 and at the position of the second bidirectional lead screw 13. One end of the movable sleeve 19 is inserted into the fixed seat 17. The positioning of the second bidirectional lead screw 13 is realized through the cooperation of the movable sleeve 19 with the polygonal connecting column 18 and the fixed seat 17, improving the stability of the structure after adjustment.

[0025] As Figure 4 shown in the figure, a limiting plate 20 is fixedly connected to one end of the polygonal connecting column 18.

A connecting plate 24 is clamped inside the two positioning seats 12 at the top of the lifting plate 10. Both sides of the connecting plate 24 are in close contact with one side of the two garbage classification bins 23 respectively.

[0029] The present utility model provides a positioning tooling for the welding production of garbage bins. The specific working principle is as follows:

[0030] The staff places the two garbage classification bins 23 to be welded and the connecting plate 24 in the positioning seats 12 on the positioning table 1 and the lifting plate 10 respectively. Then, the first bidirectional lead screw 3 is rotated to drive the two positioning plates 4 to perform a contraction movement in the square through hole 2, pushing the two garbage classification bins 23 to move on the positioning table 1 and finally clamping and positioning with the connecting plate 24 clamped on the adjustment base 9, so that the two garbage classification bins 23 and the connecting plate 24 are closely attached together for welding positioning. When the size of the garbage bin to be welded and positioned changes, the positions of the positioning pins 6 and the positioning seats 12 on the positioning table 1 and the lifting plate 10 are adjusted to position the two sides and two ends of the garbage classification bin 23 and the connecting plate 24. Then, by pulling out the movable sleeve 19 from the fixed seat 17 and rotating the movable sleeve 19, the second bidirectional lead screw 13 connected to the polygonal connecting column 18 is driven to rotate. The second bidirectional lead screw 13 drives the two driven blocks 14 to perform an unfolding movement, so that the connecting rod 15 moves and lifts the lifting plate 10, making the height of the connecting plate 24 reach a suitable position. Then, the movable sleeve 19 is inserted into the fixed seat 17 to complete the adjustment.
