[0022] It should be noted that the bottom plate support mechanism 2 includes a fixing seat and a limiting gear. The fixing seat is bolted to the top of the base 1. The limiting gear is rotatably connected to the top of the fixing seat. The position of the limiting gear on the top of the fixing seat is adjustable.

[0023] It should be noted that the driving mechanism 6 provided in the device can not only drive the downward pressure limit mechanism 7 to move to achieve position adjustment, but also synchronously drive the side panel support mechanism 4 to move to achieve position adjustment. The driving mechanism 6 synchronously drives the downward pressure limit mechanism 7 and the side panel support mechanism 4 to move, thereby ensuring that the center point position remains unchanged, facilitating assembly operation and achieving good use effect.

[0024] like Figure 1-Figure 4 As shown, in some embodiments, the side plate support mechanism 4 includes a threaded rotating cylinder 41, a guide sleeve 42, a ring gear 43, a first threaded screw 44, a guide shaft 45, a mounting seat 46, a pneumatic push rod 47 and a side support wheel 48. The threaded rotating cylinder 41 is symmetrically rotatably connected to the inner wall of the stand 3, the guide sleeve 42 is symmetrically fixedly connected to the inner wall of the stand 3 and is located on the outside of the threaded rotating cylinder 41, the ring gear 43 is fixedly connected to the surface of the threaded rotating cylinder 41 and is connected to one end of the driving mechanism 6, and the first threaded screw 44 is connected to the inner wall of the stand 3.

The pneumatic push rods 47 are electrically connected to the external control console.

[0025] It should be noted that: the structure and connection relationship of the side panel support mechanism 4 are further explained. By changing the position of the side panel support mechanism 4, the side panels installed at different positions on the base plate are clamped and fixed, and the use effect is good. When in use, the rotation of the ring gear 43 synchronously drives the threaded rotating drum 41 to rotate, and the rotation of the threaded rotating drum 41 synchronously drives the first threaded screw 44 to move to one side, and synchronously drives the mounting seat 46, the pneumatic push rod 47 and the side support wheel 48 to move. During the movement, the guide sleeve 42 and the guide shaft 45 play a role of limiting and guiding, which improves its operating stability and has a good use effect.

[0026] like Figure 1-Figure 4 As shown, in some embodiments, the positioning mechanism 5 includes an infrared ranging transmitting end 51 and an infrared ranging receiving end 52. The infrared ranging transmitting end 51 is threadedly connected to the inner wall of one set of guide shafts 45, and the infrared ranging receiving end 52 is threadedly connected to the inner wall of the guide sleeve 42 and corresponds to the position of the infrared ranging transmitting end 51.

The surface of the slide 62 is symmetrically integrally formed with bumps, and one group of the bumps is formed by a strip. The guide groove 200 passes through the outside of the stand 3 and is fixedly connected to a pointer 63. Scale lines 64 are provided on the surface of the stand 3 at positions corresponding to the position of the pointer 63. Both ends of the second threaded screw 61 pass through the outside of the stand 3 and are fixedly connected to side gears 65.

The linkage gear 67 is rotatably connected to the surface of the base 1 and is respectively connected to the side gear 65 and the ring gear 43 through the toothed synchronous belt 66. One end of the central axis of the linkage gear 67 passes through the interior of the base 1 and is fixedly connected to the output end of the drive motor 8.

[0029] It should be noted that an encoder 10 is provided on the surface of the driving motor 8 and is electrically connected to the controller 9. The encoder 10 is used to detect the number of rotations of the driving motor 8 in real time and send the data information to the controller 9. The controller 9 determines the displacement information of the downward limit mechanism 7 and the side panel support mechanism 4 based on the number of rotations data, and compares the data information with the detection of the positioning mechanism 5 to improve the displacement accuracy and achieve good use effect.

[0030] It should be noted that: the structure and connection relationship of the driving mechanism 6 are further explained. The driving mechanism 6 is set to not only drive the downward pressure limit mechanism 7 to move to achieve position adjustment, but also synchronously drive the side plate support mechanism 4 to move to achieve position adjustment. The downward pressure limit mechanism 7 and the side plate support mechanism 4 are synchronously driven to move by the driving mechanism 6 to ensure that the center point position remains unchanged, which is convenient for assembly operation and has a good use effect. When in use, the driving motor 8 rotates and synchronously drives the linkage gear 67 to rotate. The linkage gear 67 rotates and synchronously drives the side gear 65 and the ring gear 43 to rotate through the toothed synchronous belt 66. The rotation of the side gear 65 synchronously drives the second threaded screw 61 to rotate, the rotation of the ring gear 43 synchronously drives the threaded drum 41 to rotate, the rotation of the second threaded screw 61 synchronously drives the slide 62 and the downward pressure limit mechanism 7 to move to one side, the rotation of the threaded drum 41 synchronously drives the first threaded screw 44 to move and is consistent with the moving direction of the slide 62, the first threaded screw 44 synchronously drives the mounting seat 46, the pneumatic push rod 47 and the side support wheel 48 to move, and the synchronous movement of the slide 62 and the mounting seat 46 ensures that the positional relationship between the side support wheel 48 and the lower support wheel 72 remains unchanged, which is convenient for assembly operation and has a good use effect.

[0031] like Figure 1-Figure 4 As shown, in some embodiments, the downward pressure limiting mechanism 7 includes a lower hydraulic cylinder 71 and a lower support wheel 72. The lower hydraulic cylinder 71 is bolted to the bottom of the slide 62, and the lower support wheel 72 is rotatably connected to the bottom of the lower hydraulic cylinder 71. The lower hydraulic cylinder 71 is electrically connected to the external control console.

[0032] It should be noted that: the structure and connection relationship of the downward pressure limit mechanism 7 are further explained. The lower hydraulic cylinder 71 is electrically connected to the external control console to facilitate assembly and unified operation. It is used separately from the controller 9 in this device to facilitate separate control and good use effect.

[0033] like Figure 1-Figure 4 As shown, in some embodiments, the center point between the two sets of side plate supporting mechanisms 4 corresponds to the center point of the downward pressing limiting mechanism 7 and is on the same axis.

[0034] It should be noted that the same axis design ensures that the stroke of the pneumatic push rod 47 remains unchanged, which is convenient for maintaining a stable clamping force. At the same time, there is no need to adjust the clamping force, which saves time and effort and has a good use effect.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
