DETAILED DESCRIPTION

[0024] The following will be combined with the attached embodiment of the present utility model Figure 1-6 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] like Figures 1 to 6 As shown, the utility model discloses a bracket mechanism for grinding a plate roller, comprising a base 1, a sliding table 2 is arranged on the base 1, and a plate roller bracket 3 is arranged on the upper end of the sliding table 2. In this structure, the sliding table 2 is arranged on the base 1 for sliding forward and backward movement, and the sliding table 2 is equipped with a limiting arm 33, and the limiting arm 33 slides synchronously with the sliding table 2; a plurality of limiting holes 12 are opened on the side wall of the base 1 along the front-back direction, and the extending direction of the limiting holes 12 is perpendicular to the sliding direction of the sliding table 2, and at the same time, an elastic pushing member for driving the limiting arm 33 to slide along a second sliding direction is arranged between the limiting arm 33 and the sliding table 2, and the second sliding direction of the limiting arm 33 is consistent with the extending direction of the limiting hole 12, and a limiting block 34 for inserting into the limiting hole 12 is arranged on the limiting arm 33.

[0027] The working principle of this structure is as follows: since the elastic pushing member can push the limiting arm 33 along the extension direction of the limiting hole 12, the limiting block 34 can be pushed into the limiting hole 12 by the elastic pushing member to fix the plate roller bracket 3. When the plate roller bracket 3 needs to slide again, it only needs to push the limiting arm 33 in the opposite direction to make the limiting block 34 leave the limiting hole 12.

[0028] A more specific arrangement of the limiting arm 33 is as follows:

[0029] The left and right side walls of the base 1 are provided with limiting grooves 11, which extend from front to back, and the limiting holes 12 are distributed on the upper end surfaces of the limiting grooves 11; the left and right ends of the sliding platform 2 are fixedly connected with extension arms 31, and the extension arms 31 are provided with rotation holes 311, and a vertical rod 32 is arranged in the rotation holes 311 to slide up and down. The cross-sections of the rotation holes 311 and the vertical rod 32 are both circular, and the vertical rod 32 can rotate in the rotation holes 311. In this structure, the vertical rods 32 on the left and right sides of the sliding platform 2 are respectively located on the left and right sides of the base 1, and each vertical rod 32 is equipped with a limiting arm 33, which is horizontally arranged at the lower end of the vertical rod 32 and fixedly connected to the vertical rod 32, and the limiting block 34 is arranged on the upper end surface of the limiting arm 33, and the elastic pushing member is abutted between the upper end of the extension arm 31 and the upper end of the vertical rod 32, and the elastic pushing member can adopt a spring 35.

[0030] Through this structure, when the position of the plate roller bracket 3 needs to be fixed, the vertical rod 32 can be pressed downward first, and then the limit arm 33 and the limit block 34 can be turned into the limit groove 11 until the limit block 34 is aligned with the limit hole 12, and then the vertical rod 32 can be loosened to fix the plate roller bracket 3.

[0031] Furthermore, two sliding tables 2 are provided on the base 1, the sliding trajectories of the two sliding tables 2 are collinear, and the two sliding tables 2 are provided with a plate roller chuck 22 on the side facing away from each other. In this structure, tapered holes 23 are provided on the end surfaces opposite to each other of the two plate roller chucks 22. At the same time, a sliding mechanism for driving the plate roller chuck 22 to slide back and forth is provided on the sliding table 2. The sliding mechanism specifically includes a cylinder 21, which is fixedly arranged on the sliding table 2 and its piston rod is fixedly connected to the plate roller chuck 22.

[0032] This structure can not only fix the plate roller 4, but also effectively reduce the length of a single sliding table 2, which is beneficial to reducing the floor space of the base 1 and saving more space.

[0033] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
