[0031] like Figure 1 As shown, Figure 1 The left and right directions in the text are horizontal. Figure 1 The front-to-back direction is the longitudinal direction. Figure 1 The up-down direction in the vertical direction is the vertical direction. The frame body 20 can slide in the front-to-back direction relative to the walking chassis 10, and the front side of the frame body 20 forms a placement space. In each clamping assembly 30, the connecting arm 31 extends longitudinally, the end of the connecting arm 31 facing the rear side is the first end 311, and the end of the connecting arm 31 facing the front side is the second end 312. The first end 311 of the connecting arm 31 is connected to the corresponding mounting area on the mounting plate 21, and the second end 312 of the connecting arm 31 is provided with a clamp 32. By connecting the connecting arm 31 to different mounting holes 212 in the mounting area, the connection position of the clamping assembly 30 and the frame body 20 can be adjusted, so that the multiple clamps 32 in the multiple clamping assemblies 30 are spaced apart along the outer contour of the side panel, and the outer contour of the side panel is clamped together from different positions to clamp the side panel in the placement space. A plurality of running wheels are installed at the bottom of the running chassis 10. A receiving opening is provided at the position of each running wheel of the running chassis 10.

[0033] In one embodiment, the clamp 32 includes a first jaw 321, a second jaw 322 and a driving member 33. The first jaw 321 is fixed to the second end 312 of the connecting arm 31, and the second jaw 322 is hinged to the second end 312 of the connecting arm 31. The driving member 33 is used to drive the second jaw 322 to rotate in a direction close to or away from the first jaw 321, so as to correspondingly make the second jaw 322 cooperate with the first jaw 321 to clamp or loosen the side panel.

[0034] like Figure 4 As shown, the clamp 32 is disposed at the second end 312 of the connecting arm 31, the first jaw 321 in the clamp 32 remains fixed, and the second jaw 322 is hinged to the second end 312 of the connecting arm 31 and can rotate relative to the hinge point. When the side panel needs to be clamped, the driving member 33 drives the second jaw 322 to approach the first jaw 321 until the second jaw 322 and the first jaw 321 clamp the side panel in the middle. When the side panel needs to be loosened, the driving member 33 drives the second jaw 322 away from the first jaw 321 to increase the distance between the two, thereby releasing the clamping force on the side panel. The design of the clamp 32 enables the clamping assembly 30 to flexibly adapt to side panels of different sizes and shapes.

[0035] In one embodiment, the driving member 33 is a cylinder, and the output shaft of the cylinder is connected to the second jaw 322 to drive the second jaw 322 to move closer to or away from the first jaw 321. Each cylinder is provided with a corresponding valve, and each valve is mounted on the frame 20 or extends outside the frame 20 through an extension tube, so that the operator can control the valve easily.

[0037] Furthermore, the end of the second jaw 322 is connected to a contact column 3221 by a ball joint, and the ball joint allows the contact column 3221 to rotate relative to the second jaw 322 in multiple directions. When the second jaw 322 and the first jaw 321 cooperate to clamp the side panel, the contact column 3221 can adjust its own direction according to the shape of the side panel, ensuring that the contact column 3221 abuts against the side of the side panel in the most secure direction, ensuring that the contact column 3221 and the first jaw 321 achieve the best cooperation state, so that the clamp 32 can firmly clamp side panels of different shapes.

[0039] It should be noted that the mounting block 211 is determined according to the arrangement position and adjustment range of each clamping assembly 30, and one or more mounting areas are formed on the same mounting block 211 to ensure that the connecting arms 31 in each clamping assembly 30 are connected to the corresponding mounting area. The first end 311 of each connecting arm 31 is bolted to the mounting hole 212 in the mounting area, which facilitates the assembly and disassembly of the clamping assembly 30 and the mounting block 211, so that each clamping assembly 30 can be adjusted to different positions according to the different clamping requirements of the side panels of different shapes, ensuring that multiple clamping assemblies 30 can clamp the side panels together firmly.

[0040] In one embodiment, a limiting rod 22 is connected to the side of the frame 20 facing the placement space. The limiting rod 22 is arranged horizontally. Two first limiting columns 221 are respectively arranged at both ends of the limiting rod 22.

When the side panel is located in the placement space, multiple clamps 32 clamp the side panel from the top, and two first limit posts 221 simultaneously abut against the bottom of the inner wall of the side panel to abut the side panel from the inside. The upper end of each first limit post 221 is ball-jointed with an abutment post 3221 to ensure that the first limit post 221 can abut against the inner wall of the side panel from multiple directions, so that the first limit post 221 can adapt to side panels of various shapes.

[0042] In one embodiment, the frame 20 is connected to a positioning column 23 on one side of the placement space through a connecting plate. The positioning column 23 extends longitudinally and is used to cooperate with the positioning hole on the side panel so that the connecting plate abuts against the outer wall of the side panel.

[0043] Furthermore, the frame 20 is connected to the positioning column 23 through a vertically arranged connecting plate. The side panels are provided with positioning holes. The positioning column 23 extends into the placement space and extends into the positioning hole to accurately position the side panels. When the positioning column 23 extends into the positioning hole, the connecting plate abuts against the outer wall of the side panels, so that the connecting plate and the first limiting column 221 respectively press the side panels from the outer wall and the inner wall of the side panels to ensure that the side panels remain fixed in the longitudinal direction.

[0044] In one embodiment, a second limiting column 24 is connected to one side of the frame 20 facing the placement space. The second limiting column 24 extends transversely and is used to abut against the side wall of the side panel.

[0045] Furthermore, the frame body 20 is connected to the second limiting column 24 through a connecting rod, so that the second limiting column 24 extends into the placement space. A locking ring is provided at the end of the connecting rod, and a fastening bolt is passed through the locking ring. The second limiting column 24 passes through the locking ring laterally and can move laterally relative to the locking ring. The fastening bolt is used to fasten the second limiting column 24. The side panels are formed with abutment surfaces along the side surfaces in the lateral direction. The second limiting column 24 can remain fixed under the cooperation of the locking ring and the fastening bolts, and abut against the abutment surface of the side panels, so that the second limiting column 24 abuts the side panels in the lateral direction, ensuring that the side panels remain fixed in the lateral direction.

[0046] In one embodiment, a longitudinally extending slide rail 11 is disposed on the traveling chassis 10 , a slider 25 is disposed at the bottom of the frame body 20 , and a slide groove slidably matched with the slide rail 11 is formed on the slider 25 .

[0047] like Figure 3 As shown, the frame 20 is placed on the slide rail 11 through the slider 25 and can slide along the slide rail 11, so that the frame 20 can slide toward the placement space when it needs to clamp the side panel, and can slide away from the placement space after completing the detection of the side panel. The movement is convenient and stable.

[0048] In one embodiment, two adjustment components 12 are provided on the walking chassis 10, each adjustment component 12 includes an adjustment nut seat 122 and an adjustment screw 121, the adjustment nut seat 122 is connected to the walking chassis 10 and extends upward, and a screw hole that threadably matches the adjustment screw 121 is opened on the top of the adjustment nut seat 122; the adjustment screw 121 in one of the adjustment components 12 extends longitudinally and passes through the corresponding screw hole, and the adjustment screw 121 can abut the frame 20 along the longitudinal direction; the adjustment screw 121 in the other adjustment component 12 extends transversely and passes through the corresponding screw hole, and the adjustment screw 121 can abut the frame 20 along the transverse direction.

[0049] Furthermore, the two adjustment components 12 are both arranged on the top surface of the walking chassis 10, wherein the adjustment screw 121 in one of the adjustment components 12 extends longitudinally and can longitudinally abut the frame 20, so that the frame 20 slides along the slide rail 11 under the pushing action of the adjustment screw 121, so as to achieve fine adjustment of the position of the frame 20. The adjustment screw 121 in the other adjustment component 12 extends transversely and can transversely abut the frame 20, so that under the pushing action of the adjustment screw 121, the slider 25 at the bottom of the frame 20 abuts against the slide rail 11, so as to achieve the fixation of the position of the frame 20. The two adjustment components 12 cooperate with each other, so that the frame 20 can slide along the slide rail 11 according to the detection requirements of the side panels, and can also keep the frame 20 fixed during the detection process of the side panels, thereby achieving accurate detection of the side panels.
