[0058] It should be noted that the existing automated welding process for bicycle frame production requires positioning tooling to limit the position of the frame tubes for welding. However, when positioning the frame tubes, the positioning tooling often interferes with the welding equipment, thereby affecting the welding progress. It is even necessary to continuously adjust the limit position of the frame tubes during the welding process to ensure complete welding, which is inefficient and prone to welding deviations.

[0059] Specifically, in this embodiment, this solution mainly adopts the arrangement of the main frame assembly 2, the chassis assembly 4, the adjustment assembly 3 and the positioning assembly 1; during use, the positioning tool is moved to the vicinity of the welding equipment and the bicycle tube frame, and the control motor 3012 in the main control mechanism 301 is controlled according to the welding position direction of the bicycle tube frame to be welded.

[0060] Start and control the use of the distance adjustment hydraulic cylinder 3023 to pull the position between the two positioning components 1 on each adjustment component 3 so that the two on each adjustment component 3 can achieve better adaptability with the vehicle tube frame;

[0061] Place the bicycle tube frame to be welded above the positioning assembly 1 provided at the lower end, and use the positioning assembly 1 provided at the upper end to limit the upper portion of the bicycle tube frame to complete the positioning of the bicycle tube frame. Then, cooperate with another positioning tool to position another bicycle tube frame to be welded. Then, according to the butt joint condition of the welding position between the two bicycle tube frames, move the positioning tool to adjust the butt welding position. At this time, the welding position between the two bicycle tube frames is outside the two positioning tools, so that the welding equipment can perform welding.

[0062] Then, the main pushing hydraulic cylinder 306 is started and controlled to push the main regulating mechanism 301 outward, and then, in conjunction with the setting of the upper connecting frame mechanism 305, the main regulating mechanism 301 and the positioning assembly 1 and the vehicle tube frame set at the bottom can be flexibly moved outward, so that the connection between the positioning assembly 1 and the vehicle tube frame and the main frame assembly 2 forms an outward convex shape, so that the structural position on the adjustment assembly 3 is away from the welding position on the vehicle tube frame, reducing interference with the welding operation of the welding equipment, thereby providing an operable range for the welding operation, minimizing welding interruptions, and improving welding integrity and accuracy; at the same time, the position of the upper positioning suction cup 304 is lifted and moved so that the top of the upper positioning suction cup 304 is fitted with the bottom of the upper positioning plate 3054, and the upper positioning suction cup 304 is started, and the bottom of the upper positioning plate 3054 is fitted by the upper positioning suction cup 304, thereby achieving the stability of the internal structure between the adjustment components 3 at this time;

[0064] In this embodiment, by adjusting the setting of the component 3 and cooperating with the main frame component 2, during use, the positioning tool is moved to the vicinity of the welding equipment and the bicycle tube frame, and the regulating motor 3012 in the main regulating mechanism 301 is controlled according to the welding position direction of the bicycle tube frame to be welded, and the regulating motor 3012 drives the turntable and the angle frame 3013 to rotate, thereby adjusting the distance adjustment mechanism 302 and the clamping direction of the positioning component 1 to match the placement direction of the bicycle tube frame to be welded, and the bicycle tube frame to be welded is placed above the positioning component 1 set at the lower end, and the upper part of the bicycle tube frame is limited by the positioning component 1 set at the upper end to complete the positioning of the bicycle tube frame, and then cooperate with another positioning tool to position the other bicycle tube frame to be welded, and then according to the butt connection condition of the welding position between the two bicycle tube frames, the positioning tool is moved to adjust the butt connection welding position. At this time, the welding position between the two bicycle tube frames is outside the two positioning tools, so that the welding equipment can perform welding;

[0065] Then, the main pushing hydraulic cylinder 306 is started and controlled to push the main regulating mechanism 301 outward. In conjunction with the setting of the upper connecting frame mechanism 305, the main regulating mechanism 301 and the positioning assembly 1 and the vehicle tube frame arranged at the bottom can be flexibly moved outward, so that the connection between the positioning assembly 1 and the vehicle tube frame and the main frame assembly 2 forms an outward convex shape, so that the structural position of the adjustment assembly 3 is away from the welding position on the vehicle tube frame, reducing interference with the welding operation of the welding equipment, thereby providing an operable range for the welding operation, minimizing welding interruptions, and improving welding integrity and accuracy.

[0066] In conjunction with the upper positioning hydraulic cylinder 303, the position of the upper positioning suction cup 304 can be lifted and lowered so that the top of the upper positioning suction cup 304 is in contact with the bottom of the upper positioning plate 3054. The upper positioning suction cup 304 is activated to contact the bottom of the upper positioning plate 3054 through the upper positioning suction cup 304, thereby maintaining the stability of the internal structure between the adjustment components 3 at this time.

[0067] In this embodiment, by manipulating the setting of the distance adjustment mechanism 302, during use, the distance adjustment hydraulic cylinder 3023 is started and controlled to pull the position between the two positioning components 1 on each adjustment component 3, so that the two on each adjustment component 3 can achieve better adaptability with the vehicle tube frame.
