[0002] Most of the traditional welding tooling tables are used in conjunction with welding robots, and their structure includes: a tooling table panel, which is fixedly supported on a support base and located below the welding robot's welding gun. When welding, first of all, the material must be loaded, that is, the workpiece to be welded is placed on the tooling table panel, and then the welding gun on the welding robot performs welding operations on the workpiece to be welded. After welding is completed, the material is unloaded, and the completed workpiece is removed from the tooling table panel by manual or equipment, and then the material is loaded again, and then the welding of the next workpiece is carried out. The disadvantages of the traditional welding tooling table used in conjunction with the welding robot include: on the one hand, the entire tooling table panel is located in the welding station of the welding robot, so that the welding robot stops working during the loading and unloading process, which will cause the work efficiency to be very low; on the other hand, whether it is a traditional welding tooling table or an improved welding tooling table on the existing market, it does not have the function of automatic unloading. After the welding of the workpiece is completed, most of them are still unloaded manually, resulting in high labor intensity and certain safety hazards. Summary of the invention

[0028] The track frame is composed of an outer shell plate 17 with an inner groove 17a, a first track plate 18 and a second track plate 19. The support base 1 is symmetrically provided with a slide groove 1a. The outer shell plate 17 is slidably installed in the slide groove 1a through two support rods 171 arranged at the bottom. The two support rods 171 are connected by a connecting sub-rod 172. The connecting sub-rod 172 is threadedly connected to the bidirectional screw rod 13. Through the forward and reverse rotation of the bidirectional screw rod 13, the track frames on the left and right sides can move relative to or oppositely, so that the foldable tooling welding plate can be folded. 3 is folded or unfolded; the No. 1 track plate 18 and the No. 2 track plate 19 are both installed in the inner groove 17a by screw connection; the No. 1 track plate 18 and the No. 2 track plate 19 are both connected in a detachable manner, the purpose of which is to facilitate future maintenance and replacement; the stepless speed regulating motor 12 is fixed to the outer side wall of the outer shell plate 17 on the left side. When in use, it is controlled by an external speed regulator. Through the control of the speed regulator, the stepless speed regulating motor 12 is started and stopped once, and the positions of the foldable tooling welding plates 3 in the two directions will be swapped once.

[0029] The shapes of the inner groove 17a, the No. 1 track plate 18, and the No. 2 track plate 19 are adapted to each other. When the No. 1 track plate 18 and the No. 2 track plate 19 are installed in the inner groove 17a by screws, there is a gap between the inner and outer end surfaces of the three, and the gap constitutes a circular track. The circular track is formed by the overlap of the circular track for moving the slide bar 9 and the circular track for moving the walking wheel 10.

[0030] Furthermore, in order to ensure that the operator is not injured by the welding slag splashed by the welding robot during the loading process and to prevent the strong light during welding from injuring the eyes, a protective isolation plate 21 is provided above the track frame. The isolation plate 21 is made of a filter material with high temperature resistance and a certain strength. The isolation plate 21 is a U-shaped structure, and the two ends are respectively fixed on the support base 2.

[0031] Working process:

[0032] The welding objects when the present invention is used are generally rectangular or square plates with welding holes and columnar components matching the welding holes. The welding purpose is to weld the columnar components to the plates through the welding holes.

[0033] The foldable tooling welding plate 3 has two states, one is an unfolded state, such as Figure 3 As shown, one is a folded state; the corresponding state can be changed according to actual conditions. This embodiment takes the unfolded state as an example.

[0034] Initially, the two foldable tooling welding plates 3 are respectively located at the front lower and rear upper positions, wherein the foldable tooling welding plate 3 at the rear upper position is placed with a plate with a welding hole and a columnar component initially placed in the welding hole, and the plate is fixed and clamped by fine-tuning the positioning assembly and the abutment plate 71. The welding robot is installed on the support base 2 through the slide rail 23 and the guide rail 24, and the welding gun on the welding robot can correspond to the position of the columnar component and the welding hole on the rear upper foldable tooling welding plate 3, and a plate collection box is placed under the unloading baffle 20.

[0035] When in use, the welding robot is driven by an external control system to weld the columnar component and the welding hole. During the welding process of the welding robot, the operator loads the foldable tooling welding plate 3 located in the front lower position. The loading process is to first place the plate with the welding hole on the foldable tooling welding plate 3, and use the L-shaped limit block 4 to clamp the two sides of the front end of the plate, and then vertically place the columnar component into the welding hole.

[0036] After the welding robot completes welding, the stepless speed regulating motor 12 is controlled by an external motor controller, and the foldable tooling welding plate 3 is driven to move counterclockwise from front to back on the circular track through the sprocket mechanism 8, the slide bar 9 and the walking wheel 10. After the stepless speed regulating motor 12 is started and stopped once, the positions of the two foldable tooling welding plates 3 at the front lower and rear upper positions are swapped once, that is, the foldable tooling welding plate 3 at the rear upper position moves to the front lower position, and the foldable tooling welding plate 3 at the front lower position moves to the rear upper position and a new round of welding operation is performed; wherein the foldable tooling welding plate 3 at the rear upper position is in the process of moving, and the welded plate thereon will be relatively abutted against the unloading baffle 20 below, thereby unloading the welded plate from the foldable tooling welding plate 3 and falling into the plate collection box.
