Specific embodiments

[0027] The following will further elaborate on the specific embodiments of the present utility model in conjunction with the attached Figures 1-4 drawings.

[0028] As Figures 1-4 shown, a device for reducing the deformation of a steel door leaf includes a frame body 5. A first clamping plate 1 that slides relative to each other front and back is provided on the frame body 5, and two second clamping plates 2 that can slide left and right are also provided on the frame body 5;

[0029] A vertically sliding support plate 3 is provided on the frame body 5, and a plurality of support rods 4 with adjustable lengths are provided on the support plate 3.

[0030] In this device, the door leaf to be welded is placed on the frame body 5, and then the first clamping plate 1 is used to clamp the transverse end of the door leaf, and the second clamping plate 2 is used to complete the clamping of the longitudinal end of the door leaf. In this way, the entire door leaf is fixed, and the deformation during welding can be reduced to a certain extent. Moreover, at this time, the first clamping plate 1 and the second clamping plate 2 can match steel door leaves of various sizes.

[0031] Third cylinders are respectively fixed at the left end and the right end of the frame body 5, and the other end of the third cylinder is fixedly connected to the second clamping plate 2. The movement of the third cylinder drives the second clamping plate 2 to slide, thereby completing the clamping of the door leaf.

[0032] Furthermore, after the door leaf is clamped and fixed, the support plate 3 slides vertically to an appropriate height, and then the horizontal position and length of the support rod 4 are adjusted to complete the support of the door leaf. In this way, the deformation of the door leaf during welding can be reduced.

[0033] The middle part of the frame body 5 is a hollow structure, and the support plate 3 can slide through the frame body 5;

[0034] A support plate 6 is fixed to the lower end of the frame body 5, and a first cylinder is fixed to the upper end of the support plate 6. The upper end of the first cylinder is fixedly connected to the support plate 3.

[0035] A hollow rectangular hole is provided on the frame body 5, and the support plate 3 can slide through the rectangular hole. By the movement of the first cylinder, the support plate 3 is driven to slide vertically.

[0036] A sleeve 7 is fixed to the upper end of the support plate 6, and a guide rod 8 is slidably arranged in the sleeve 7. The upper end of the guide rod 8 penetrates through the sleeve 7 and is fixedly connected to the support plate 3.

[0037] The guide rod 8 will not be separated from the sleeve 7. Through the cooperation between the guide rod 8 and the sleeve 7, the vertical sliding effect of the support plate 3 is ensured.

[0038] A plurality of rectangular blocks 9 that slide horizontally are provided on the support plate 3, and the support rod 4 is connected to the rectangular blocks 9. The distance between two adjacent rectangular blocks 9 is always equal.

[0039] In this device, there are a plurality of rectangular blocks 9. The support rod 4 is fixedly connected to the rectangular blocks 9. The movement of the rectangular blocks 9 drives the support rod 4 to slide horizontally. Because when welding, the horizontal rectangles between the welding points are almost the same. Therefore, we adjust the horizontal position of the support rod 4 to try to match the welding points as much as possible, so as to reduce the degree of deformation during welding. The support rod 4 supports the door leaf to reduce deformation.

[0040] A plurality of cross scissor-like link structures are provided on the support plate 3, and the rectangular blocks 9 are connected to the link structures;

[0041] The link structure includes a first link 10 and a second link 11 that are cross-hinged to each other. The rectangular block 9 is connected to the hinge joints of the first link 10 and the second link 11;

[0042] The first link 10 is hinged to the second link 11 in an adjacent link structure, and the second link 11 is hinged to the first link 10 in an adjacent link structure.

[0043] In this device, a scissor-like link structure is adopted. This structure is relatively common, so no more details will be elaborated. The rectangular block 9 is fixedly connected to the hinge shafts at the hinge joints of the first link 10 and the second link 11. In this way, when the link structure moves, it drives the rectangular block 9 to move together, and it can ensure that the distance between two adjacent rectangular blocks 9 is always the same, so as to match the welding points.

[0044] A fixed rod 12 is fixed to the support plate 3, and the fixed rod 12 slidably penetrates through a plurality of rectangular blocks 9.

[0045] In this device, the setting of the fixed rod 12 ensures the horizontal sliding effect of the rectangular blocks 9.

[0046] A second cylinder 13 is fixed on the support plate 3, and the second cylinder 13 is fixedly connected to the outermost rectangular block 9.

[0047] Through the second cylinder 13, the outermost rectangular block 9 is driven to slide horizontally. When the outermost rectangular block 9 slides, it drives a plurality of rectangular blocks 9 to move together, and then drives a plurality of support rods 4 to move.

[0048] A bidirectional threaded rod 14 is rotatably provided on the frame body 5. The thread directions of the bidirectional threaded rod 14 are opposite. Two first clamping plates 1 are respectively threadedly connected to both sides of the bidirectional threaded rod 14. When the bidirectional threaded rod 14 rotates, it drives the two first clamping plates 1 to slide relatively;

[0049] A guide rod 15 is fixed to the upper end of the frame body 5, and the guide rod 15 can slidably penetrate through the two first clamping plates 1.

[0050] A hand wheel is fixed on the outside of the bidirectional threaded rod 14. By driving the hand wheel to rotate, the bidirectional threaded rod 14 is driven to rotate, and then the two first clamping plates 1 are driven to slide relatively. And the threaded connection has a good self-locking effect, which can well ensure the stability of the first clamping plate 1 after sliding.

[0051] The support rod includes a hollow round tube 16. Second threaded rods 17 that slide back and forth are respectively provided on the front and rear sides of the round tube 16. The outer ends of the second threaded rods 17 penetrate through the round tube 16 and are located outside the round tube 16. Nuts 18 are rotatably connected to both the front and rear ends of the round tube 16. The nuts are threadedly connected to the second threaded rods 17. Square plates 19 are fixed to the outer ends of each second threaded rod 17.

[0052] In this device, a guide disk is fixed to the inner end of the second threaded rod 17. A plurality of guide grooves are provided on the round tube 16. Guide blocks that can slide are provided in the guide grooves. The guide blocks penetrate through the guide grooves and are fixedly connected to the guide disk, so as to achieve the horizontal sliding effect of the second threaded rod 17.

[0053] By rotating the nuts 18, the second threaded rods 17 are driven to slide horizontally, and then the square plates 19 are driven to move, completing the support for the door leaf. In this way, the deformation amount can be reduced during subsequent welding.

[0054] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
