[0024] See also Figure 1-Figure 4 The utility model provides a correction device for a box-type vehicle body, which is used to correct the box body (plate-shaped) to ensure its flatness and avoid distortion, deformation, etc. Specifically, it includes a frame 1 and multiple correction mechanisms, which are described in detail below:

[0025] The frame 1 is used as a support and mounting carrier for placing the sheet material and installing the correction mechanism;

In the present embodiment, the frame 1 is a frame-shaped structure, which is welded from square steel. Specifically, it includes a rectangular frame, which is horizontally arranged. Legs are arranged at the bottom of the frame for supporting the rectangular frame. The rectangular frame serves as a support and mounting carrier. A support portion is arranged on the inner side of the rectangular frame, which can support the sheet material to form a placement area. In order to facilitate material movement, a roller conveyor can be arranged in the placement area. While achieving support, it is convenient to move the sheet material, that is, it is convenient to load and unload the material. In the present application, the roller conveyor includes a plurality of rollers, which have a certain radial bearing capacity. At the same time, there is a certain gap between two adjacent rollers, which is used for correcting the pressing of the material below.

[0027] Horizontal guide rails 11 are provided on both sides of the placement area, and the horizontal guide rails 11 are horizontally fixed on both sides of the rectangular frame.

[0028] The correction mechanism includes a first correction mechanism 3 and a second correction mechanism 2, and the structures thereof are described in detail below;

[0029] The first correction mechanism 3 includes a first slide 31, which is slidably mounted on the horizontal guide rail 11. There are two of them and they are symmetrically arranged. A vertically arranged first vertical guide column 32 is fixed on the first slide 31. The first vertical guide column 32 has an upper and lower end. A first bracket plate 34 and a second bracket plate 38 are fixed to the top and bottom of the first vertical guide column 32, respectively. The two ends of the first bracket plate 34 and the second bracket plate 38 are rigidly connected to the two first vertical guide columns 32, respectively, to form a whole. A first pressing plate 33 and a second pressing plate 39 are vertically slidably mounted on the two first vertical guide columns 32. The first pressing plate 33 is located at the upper end of the second pressing plate 39. Specifically, the first pressing plate 33 is located at the upper end of the placement area for pressing and correcting the top surface of the sheet material. The second pressing plate 39 is located at the lower end of the placement area for pressing and correcting the bottom surface of the sheet material. The first pressing plate 33 and the second pressing plate 39 are located on the same vertical plane for material pressing correction. A first oil cylinder 35 is vertically fixed on the first bracket plate 34. There are two first oil cylinders 35 that are symmetrically arranged on the first bracket plate 34, and their output ends are arranged downward. After passing through the first bracket plate 34, they are rigidly connected to the first pressing plate 33, and are used to drive the first pressing plate to move up and down. A second oil cylinder 381 is vertically fixed at the lower end of the second bracket plate 38. There are two second oil cylinders that are symmetrically arranged. The output ends of the second oil cylinders are arranged upward. After passing through the second bracket plate 38, they are rigidly connected to the second pressing plate 39, and are used to drive the second pressing plate 39 to move up and down. The first pressing plate 33 and the second pressing plate 39 are strip structures. The lower bottom surface of the first pressing plate 33 and the upper bottom surface of the second pressing plate 39 serve as pressing surfaces for squeezing the sheet material to make it flat.

[0030] The second correction mechanism 2 is one or two. In the present embodiment, it is two and is respectively arranged at the two ends of the first correction mechanism 3, i.e., the front end and the rear end. It includes a second slide 21. The second slide 21 is two and symmetrically slid on the two horizontal guide rails 11. A second vertical guide column 22 is vertically arranged on the second slide 21. A third bracket plate 24 is fixed on the top of the second vertical guide column 22. The two ends of the third bracket plate 24 are rigidly connected to the two second vertical guide columns 22 respectively. At the same time, a third pressing plate 23 is vertically slid on the second vertical guide column 22. The third pressing plate 23 is located above the placement area and is used for pressing and correcting the top surface of the sheet. A third oil cylinder 25 is vertically fixed on the third bracket plate 24. The third oil cylinder 25 is two and symmetrically arranged. The output end of the third oil cylinder 25 passes downward through the third bracket plate 24 and is connected to the third pressing plate 23, which is used to drive the third pressing plate to slide vertically to achieve pressing.

[0031] In order to improve the pressing effect, in the present application, an elastic pressing mechanism is arranged at the lower end of the first pressing plate 33 and the third pressing plate 23. The elastic pressing mechanism is multiple and arranged in sequence along the length direction of the first pressing plate 33 or the third pressing plate 23. Preferably, there are at least three of them, which are equidistantly arranged along the length direction of the first pressing plate or the second pressing plate.

[0032] Specifically, the elastic pressing mechanism includes a guide rod 37 vertically slidably mounted on the first pressing plate 33 or the third pressing plate 23. There are at least two guide rods 37 and they are arranged in parallel. A pressing block 36 is fixed at the lower end of the guide rod. The pressing block 36 is rigidly fixed to the lower end of the guide rod 37 of the same mechanism, so that the guide rod and the pressing block form a whole. At the same time, an elastic component is provided on the first pressing plate 33 or the third pressing plate 23. The elastic component makes the pressing block tend to move downward to achieve elastic contact. In this embodiment, the elastic component is a compression spring, which is sleeved on the guide rod. The upper end of the elastic component contacts the bottom surface of the first pressing plate 33 or the third pressing plate 23, and the lower end of the elastic component contacts the top of the pressing block. When the upward force borne by the pressing block is greater than the elastic force of the elastic component, the pressing block is forced to move upward; the pressing block is strip-shaped, specifically, a rectangular columnar structure, and the length direction of the pressing block is parallel to the length direction of the first pressing plate 33 or the third pressing plate 23.

[0033] In order to avoid scratching the sheet material due to rigid contact between the pressing block and the sheet material, a rubber layer is provided at the lower end of the pressing block. The thickness of the rubber layer is less than 5mm, which plays the purpose of elastic contact and avoids scratching the surface of the sheet material.

[0034] In order to improve the degree of automation and reduce labor intensity, the frame 1 is provided with driving mechanisms that are the same in number and one-to-one correspondence with the correction mechanisms. The driving mechanisms are cylinders or screws. When they are screws, they also include motors and nuts. The nuts are fixed on the slides, and the screws are threadedly connected to the nuts. The slides are driven to slide horizontally through the rotation of the screws. Two driving mechanisms are provided on each correction mechanism, which are respectively used to drive the two slides on the correction mechanism to move, so as to avoid the generation of force arms that affect the sliding effect.
