DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0020] As Figures 1-5 shown in the welding tooling for assembling the skateboard assembly group, it includes a base 1. At the four corners of the top of the base 1, there are respectively two oil cylinder seat positioning seats 2 and connecting ear seat positioning seats 12. Two oil cylinder seat spacers 3 are installed through the sides of the oil cylinder seat positioning seats 2. A slider positioning shaft 5 and an oil cylinder seat positioning shaft 6 are respectively slidably inserted into the interiors of the two oil cylinder seat spacers 3. On one side of the connecting ear seat positioning seat 12, there is a connecting ear seat positioning plate 16. The connecting ear seat positioning plate 16 is installed on the top of the base 1. A connecting ear seat spacer 15 is installed through the side of the connecting ear seat positioning plate 16. A connecting ear seat positioning shaft 13 is inserted between the connecting ear seat spacer 15 and the connecting ear seat positioning seat 12. A plurality of longitudinal middle beam positioning plates 7 are installed on the top of the base 1. The oil cylinder seat positioning shaft 6 is used to be inserted into the through hole of the oil cylinder seat in the skateboard assembly, while the slider positioning shaft 5 abuts against the side of the square tube arranged longitudinally. The connecting ear seat positioning shaft 13 is used to be inserted into the connecting ear seat in the skateboard assembly. The plurality of longitudinal middle beam positioning plates are used to support the multiple middle beam square tubes in the skateboard assembly.

[0021] A pipe end positioning shaft 14 is installed through the side of the connecting ear seat positioning seat 12. The pipe end positioning shaft 14 is used to laterally limit one end of the two longitudinally arranged square tubes.

[0022] On one side of the two connecting ear seat positioning plates 16, there are both skateboard oil cylinder lower support positioning seats 17. The skateboard oil cylinder lower support positioning seats 17 are installed on the top of the base 1. An oil cylinder support positioning shaft 18 is installed through the top end of the skateboard oil cylinder lower support positioning seat 17. A steel pipe positioning plate 19 is installed at the top end of the oil cylinder support positioning shaft 18. The steel pipe positioning plate 19 presses on the top of one of the horizontally arranged square tubes. The oil cylinder support in the skateboard assembly is assembled on the top of one of the horizontally arranged square tubes. The inner cavity of the oil cylinder support can allow the steel pipe positioning plate 19 to pass through, and the oil cylinder support positioning shaft 18 is inserted between the oil cylinder support and the top end of the connecting ear seat positioning plate 16 to fix the position of one of the horizontally arranged square tubes.

[0023] On one side of the two oil cylinder seat positioning seats 2, there are both hook bucket plate inner positioning seats 8. The two hook bucket plate inner positioning seats 8 are installed on the top of the base 1. The hook bucket plate inner positioning seats 8 are used to press on the top of the other horizontally arranged square tube to limit its position.

[0024] The sides of the plurality of longitudinal middle beam positioning plates 7 are respectively in a stepped shape or an arc shape, which is convenient to be set according to the horizontal plane or arc surface at the bottom of the square tube, and is convenient to support the square tube.

[0025] On the other side of each of the two oil cylinder seat positioning seats 2, a push rod seat 20 is provided. The push rod seat 20 is installed on the top of the base 1, and a screw tube 4 is installed on the top of the push rod seat 20. A threaded push rod 9 is inserted into the internal thread of the screw tube 4. In the skateboard assembly, the oil cylinder seat is assembled on the top of the longitudinally arranged square tube. By rotating the threaded push rod 9, the threaded push rod 9 moves spirally in the screw tube 4, facilitating one end of the threaded push rod 9 to abut against the side of the oil cylinder seat, thereby playing a role in laterally limiting the oil cylinder seat.

[0026] Between the two oil cylinder seat positioning seats 2 and the connecting ear seat positioning seat 12, a support square tube 10 and a fixed stop tube 11 are provided. Both the support square tube 10 and the fixed stop tube 11 are installed on the top of the base 1. The support square tube 10 is used to support the base of the longitudinally arranged square tube in the skateboard assembly, and the fixed stop tube 11 is used to limit one side of the longitudinally arranged square tube, preventing the longitudinally arranged square tube from shifting in position when being bottled with the horizontally arranged square tube.

[0027] Working principle: First, in the two horizontally arranged square tubes in the skateboard assembly, one horizontally arranged square tube is placed on the bottom ends of the two hook bucket plate inner positioning seats 8, and the other horizontally arranged square tube is placed on the tops of multiple arc-shaped longitudinal middle beam positioning plates 7. Then, the two longitudinally arranged square tubes in the skateboard assembly are respectively placed on the tops of the four support square tubes 10. Next, the two connecting ear seats in the skateboard assembly are placed at the ends of the two longitudinally arranged square tubes. By inserting one end of the two push connecting ear seat positioning shafts 13 into the inner holes of the two connecting ear seats, the positions of the two connecting ear seats are fixed. Then, the two oil cylinder seats are placed on the tops of the other ends of the two longitudinally arranged square tubes, and then the two oil cylinder seat positioning shafts 6 are pushed into the two oil cylinder seats. Next, multiple middle beam square tubes are placed on the tops of multiple stepped longitudinal middle beam positioning plates 7, and the two ends of the multiple middle beam square tubes are respectively in contact with the sides of the two horizontally arranged square tubes, thereby completing the bottling and fixing of multiple components in the skateboard assembly, facilitating subsequent welding operations.
