[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 to 6 shown, the present utility model provides a fixture for working roll processing, including an operating board 1. Clamping mechanisms 2 are installed at both the left and right ends of the operating board 1. The two groups of clamping mechanisms 2 are connected by a moving mechanism 3, and the moving mechanism 3 is located at the bottom of the operating board 1;

[0025] The clamping mechanism 2 includes a lifting board 21, an arc plate 22, a connecting block 23, a transmission rod 24, and a round block 25. Both sides of the arc plate 22 are fixedly installed on the top surface of the lifting board 21 through stabilizing blocks. The bottom surface of the connecting block 23 is fixedly connected to one side of the top surface of the lifting board 21. The outer circle of one end of the transmission rod 24 is rotatably connected to the inner wall of the connecting block 23, and the other end of the transmission rod 24 is fixedly connected to the inner wall of the round block 25.

[0026] Adopting the above solution: The clamping mechanism 2 is moved to a suitable position through the moving mechanism 3, so that the working roll can be fixed by the clamping mechanism 2. When fixing the working roll, an adjustable clamping force is available, which can adapt to working rolls of different diameters and lengths, facilitating workers to more easily fix the working roll and keep it stable during the processing, thereby improving work efficiency and processing accuracy.

[0027] As Figures 1 to 6 shown, scale rulers are fixedly connected to both sides of the top surface of the operation board 1, support legs are equidistantly installed at the four corners of the bottom surface of the operation board 1, sliders 211 are fixedly connected to both sides of the top surface of the lifting board 21, and a moving sleeve 212 is fixedly connected to the middle end of the bottom surface of the lifting board 21. Fixed pieces are provided on both sides of the connecting block 23. Chutes adapted to the sliders 211 are opened on both sides of the top surface of the operation board 1 away from the scale rulers, and the two chutes are arranged in parallel.

[0028] Adopting the above solution: Through the insertion hole opened inside the arc-shaped plate 22 located at the right end of the operation board 1, it is convenient to connect the transmission rod 24 with an external driving device, thereby driving the working roller to rotate. The designs of the moving sleeve 212 and the slider 211 play the role of facilitating the movement of the arc-shaped plate 22 and the lifting board 21.

[0029] As Figures 1 to 6 shown, the moving mechanism 3 includes a bidirectional threaded rod 31, a driving motor 32, and a limiting plate 33. The surface of the bidirectional threaded rod 31 is threadedly connected to the inner wall of the moving sleeve 212. The outer rings at both ends of the bidirectional threaded rod 31 are rotatably connected to the inner walls of the limiting plates 33 through bearings. One end of the bidirectional threaded rod 31 penetrates through the limiting plate 33 at the right end and is spline-connected to the output end of the driving motor 32. The bottom surfaces of the two limiting plates 33 are fixedly connected to both sides of the bottom surface of the operation board 1. Connecting frames are fixedly connected to both sides of the driving motor 32, and one ends of the connecting frames are connected to the inner side of the right end of the operation board 1. A slide rail adapted to the moving sleeve 212 is opened inside the operation board 1, and the two clamping mechanisms 2 are located on the same horizontal line.

[0030] Adopting the above solution: By driving the bidirectional threaded rod 31 to rotate through the driving motor 32, the clamping mechanism 2 can be driven to move, which is convenient for adjusting the clamping mechanism 2 according to the diameter and length of the working roller, saving time and effort in use and improving work efficiency. The design of the connecting frame facilitates the fixing of the driving motor 32 and ensures the stability of the driving motor 32 during operation.

[0031] The working principle and usage process of the present utility model: When it is necessary to fix the working roller, start the driving motor 32 to drive the bidirectional threaded rod 31 to rotate, thereby driving the two moving sleeves 212 to approach each other, and then driving the arc-shaped plate 22 to approach each other. When the arc-shaped plate 22 is moved to a position suitable for clamping the working roller, adjust the lifting board 21 to a suitable height according to the diameter of the working roller, then place both ends of the working roller on the arc-shaped plate 22, and finally connect the transmission rod 24 and the working roller through the round block 25 to clamp the working roller.
