[0029] The left side of the upper end of the tooling bracket 1 is fixedly connected to the edge positioning component I3, and the tooling bracket 1 is provided with four clamping positioning components 4 that span the tooling bracket 1. The four clamping positioning components 4 are arranged on the tooling bracket 1 at intervals in the horizontal direction, and an edge positioning component II5 is provided between adjacent clamping positioning components 4 and fixed on the tooling bracket 1.

[0030] Combine Figure 4 、 Figure 5 As shown, the side positioning assembly II5 is used to perform transverse positioning on the right side of the shorter workpiece, and the side positioning assembly I3 is used to perform transverse positioning on the left side of the workpiece.

[0031] Combine Figure 3 As shown, the clamping and positioning assembly 4 spans the tooling bracket 1, and a pressure strip 42 is fixedly connected to the pressure positioning base 41, and an inverted T-shaped slot 43 is formed between the pressure strip 42 and the pressure positioning base 41. Two slide blocks 44 are slidably connected in the T-shaped slot 43, and the lower end of the slide block 44 is connected to a screw nut pair I. The two ends of the screw of the screw nut pair I rotate in opposite directions, and the two ends of the screw are respectively connected to the two slide blocks 44 through two movable nuts. The upper ends of the two slide blocks 44 are fixedly connected to a clamping head 45, and the two clamping heads 45 are installed oppositely. One end of the screw nut pair I is transmission-connected with a driving member I 46, and the driving member I 46 is fixedly connected to one side of the clamping and positioning base 41. The screw nut pair I is installed in the clamping and positioning base 41, and its extension direction is parallel to the length direction of the pressure strip 42. The driving member I 46 drives the two slide blocks 44 through the screw nut pair I, thereby driving the two clamping heads 45 to perform centering and clamping movement.

[0032] The four hydraulic motors in the clamping and positioning assembly 4 are controlled by four valves, ensuring independent operation of each motor and significantly improving tooling compatibility. Furthermore, hydraulic pressure detection and control are integrated to freely adjust the hydraulic pressure, achieving variable clamping and release forces, preventing tooling from jamming during centering and clamping.

[0033] A shooting switch 11 is also installed on the pressing and positioning base 41 to ensure the safety of the tooling during loading and unloading and welding.

[0034] Example 1, combined with Figure 1 、 Figure 2The three clamping and positioning assemblies 4 on the right side are shown, and the lower ends of the clamping and positioning base 41 are slidably connected to the tooling bracket 1 through the guide rail slider assembly 6.

The driving part Ⅱ8 is fixedly installed on the tooling bracket 1, and the screw nut pair Ⅱ7 is installed on the tooling bracket 1, and its extension direction is parallel to the length direction of the tooling bracket 1. The guide rail extension direction of the guide rail slider assembly 6 is parallel to the extension direction of the screw nut pair Ⅱ7. The driving part Ⅱ8 can drive the clamping and positioning base 41 to move along the guide rail through the screw nut pair Ⅱ7.

The guide rail and slider assembly 6 is equipped with an accordion shield assembly 9 to ensure a long service life. During the processing, dust will not enter the guide rail and avoid affecting the movement.

[0038] Each slider is equipped with a manual oil filling port to facilitate later maintenance.

[0039] Each mobile assembly is equipped with a drag chain to facilitate wiring and ensure the overall aesthetics of the tooling.

If the workpiece interferes with the clamping component, consider moving the centering clamping component as a whole. At this time, it is necessary to control the driving component II8 to control the direction of movement to avoid interference with the workpiece and achieve loading.

[0046] 4. At this time, the workstation starts welding;

[0047] 5. At this point, the tank loading process is completed;
