[0046] The driving hole is correspondingly arranged at the stroke of the output end of the driving member 56. The driving plate 57 can slide in the driving hole. The driving member 56 drives the driving plate 57 to slide in the driving hole, driving the adjustment plate 54 to move on the slide rail, thereby adjusting the position of the clamping jaw 55, so that the clamping jaw 55 can clamp or put down the supporting roller, thereby realizing the rapid grasping of the supporting roller.

[0047] like Figures 4 to 6 As shown, the clamping jaw 55 includes: a first clamping jaw group and a second clamping jaw group, the adjusting plate 54 includes: a first adjusting plate and a second adjusting plate, the first clamping jaw group is arranged on the first adjusting plate, the second clamping jaw group is arranged on the second adjusting plate, and the clamping mechanism 5 also includes: a synchronization plate 81 and a synchronization rod 82.

[0048] In this embodiment, a flexible layer is provided on the clamping part of the clamping jaw 55.

The synchronization rod 82 can slide in the long hole, and the middle of the synchronization plate 81 is rotatably connected to the fixed plate 51 through the center axis.

[0050] When the supporting roller needs to be clamped, the first adjustment plate and the second adjustment plate are driven by the driving member 56 to move relatively and approach each other, and the synchronization rod 82 slides in the long hole on the synchronization plate 81, so that the synchronization plate 81 rotates around the central axis, ensuring that the movement displacement of the first adjustment plate and the second adjustment plate is the same, and ensuring that the first clamping jaw group and the second clamping jaw group can clamp the supporting roller. In this embodiment, the driving member 56 can be a cylinder, a motor or a hydraulic cylinder, as long as it can move in a straight line.

[0051] like Figures 4 to 6 As shown, the clamping mechanism 5 further includes a rotating mechanism. The rotating mechanism includes a rotating member 71 and a rotating plate 72, one end of the rotating plate 72 is connected to the output end of the rotating member 71, and the other end is connected to the fixed plate 51, the rotating member 71 is arranged on the connecting plate 61, and the rotating member 71 is used to drive the rotating plate 72 to rotate.

[0052] The rotating plate 72 is driven to rotate by the rotating member 71 to drive the fixed plate 51 to rotate, thereby rotating the clamping jaw 55, and rotating the clamping jaw 55 to a suitable angle for clamping the supporting roller, ensuring that the clamping jaw 55 can clamp the supporting roller.

[0053] like Figure 3 to Figure 4 As shown, the visual mechanism 6 includes: a telescopic rod 62 and a photographing device 63. One end of the telescopic rod 62 is connected to the connecting plate 61, and the other end is connected to the photographing device 63, and the photographing device 63 is used to photograph the supporting wheels or the chassis 13.

[0054] The visual mechanism 6 is moved to the top of the supporting roller or chassis 13 by the mobile assembly 3, and the supporting roller or chassis 13 is photographed by the photographing device 63, and the photographed photos are transmitted to the control system, so that the control system moves the clamping mechanism 5 according to the photographed photos. The position of the photographing device 63 relative to the mobile assembly 3 can be adjusted by adjusting the length of the telescopic rod 62, so that the photographing device 63 can photograph supporting rollers or chassis 13 of different models. In this embodiment, the photographing device 63 can be a 3D camera.

[0055] like Figures 1 to 3 As shown, the moving assembly 3 includes: two support frames 31, a crossbeam 32, and a moving mechanism. The loading assembly 1 and the loading assembly 2 are both arranged between the two support frames 31, the crossbeam 32 is slidably arranged on the two support frames 31, and the moving mechanism is slidably arranged on the crossbeam 32. The moving mechanism includes: a moving frame 33, a rack, a lifting column 34, and a moving motor 35.

[0056] By slidingly setting the crossbeam 32 on the support frame 31 and slidingly setting the moving mechanism on the crossbeam 32, the moving mechanism can move between the loading component 2 and the loading component 1, and the moving motor 35 drives the gear to rotate, and the gear engages with the rack to make the lifting column 34 move up and down, so that the clamping jaw 55 moves up and down, and moves the clamping jaw 55 to the clamping point of the supporting wheel or the placement point of the supporting wheel.

[0057] like Figures 1 to 3 As shown, the feeding assembly 2 comprises: a feeding frame 21 and a positioning seat 22. The positioning seat 22 is arranged on the feeding frame 21, and the positioning seat 22 is used to place the supporting roller.

[0058] Grooves are provided on the positioning seat 22 at the two ends corresponding to the supporting rollers, so that the two ends of the supporting rollers are embedded in the grooves to realize the positioning of the supporting rollers, making it easier for the clamping assembly 4 to grab the supporting rollers.

[0059] like Figures 1 to 3 As shown, the material loading assembly 1 comprises: a loading platform 11, a universal wheel and a rotating mechanism 12. The universal wheel is arranged on the material loading platform 11, the rotating mechanism 12 is arranged on the material loading platform 11, and one end of the rotating mechanism 12 is connected to the chassis 13.

[0060] The excavator chassis 13 on the loading assembly 1 can be moved by the universal wheel to different workstations to improve the production efficiency of the excavator chassis 13. The excavator chassis 13 can be rotated by the rotating mechanism 12 to a required processing angle to improve production efficiency.

[0061] In general, the present application provides a clamping device, which moves the clamping component 4 to the top of the chassis 13 through the moving component 3, and the visual mechanism 6 photographs the installation point on the chassis 13 to determine the coordinates of the installation point to be placed, and the moving component 3 moves the clamping component 4 to the top of the loading component 2, and the visual mechanism 6 photographs the loading component 2, and transmits the photographed photos to the control system, and the control system makes a judgment based on the photographed photos. If the supporting roller is not photographed, the moving component 3 moves the clamping component 4 and moves the visual mechanism 6 to the next shooting point until the supporting roller is photographed. The control system performs calculation and analysis based on the position of the supporting roller in the photographed photos, controls the moving component 3 to move the clamping mechanism 5 to the clamping position, and clamps the supporting roller through the clamping mechanism 5. The control system then moves the clamping component 4 according to the coordinates of the previously photographed installation point, and places the supporting roller at the installation point on the chassis 13 through the clamping mechanism 5, so as to achieve fast and accurate movement of the supporting roller to the installation point, and effectively improve the installation efficiency of the supporting roller.

[0062] In this embodiment, the shooting position of the mounting point of the chassis 13 is pre-set according to the model of the chassis 13 and the model of the supporting roller, as long as the mounting point can be completely photographed. The shooting position of the supporting roller on the feeding component 2 is pre-set according to the model of the supporting roller, so that after the control system determines that the supporting roller is not photographed, it can immediately control the moving component 3 to move the visual mechanism 6 to the next shooting position, ensuring that the supporting roller is quickly and accurately moved to the mounting point.
