Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0022] like Figures 1 to 4As shown, the utility model provides a roller frame bracket processing fixture, including a base plate 1, a bracket body 2 is arranged on the top of the base plate 1, the bottom of the bracket body 2 is in contact with the top of the base plate 1, both sides of the bottom of the base plate 1 are fixedly connected with U-shaped plates 3, the four corners of the bottom of the U-shaped plate 3 are movably connected with rollers 4 through axle pins, and a limiting component 5 for limiting the U-shaped plate 3 is arranged on the top of the base plate 1.

[0023] refer to Figure 1-4 As shown, the limit assembly 5 includes a motor 51, the top of the motor 51 is fixedly connected to the bottom of the base plate 1, the output end of the motor 51 is fixedly connected to a rotating plate 52, both sides of the top of the rotating plate 52 are provided with rotating frames 53, the top of the rotating plate 52 is movably connected to the rotating frame 53 through an axle pin, the outer side of the rotating frame 53 is fixedly connected to a placing plate 54, the top of the placing plate 54 is fixedly connected to a limit plate 55, and the top of the limit plate 55 passes through the top of the base plate 1.

[0024] As a technical optimization scheme of the utility model, through the mutual cooperation of the motor 51, the rotating plate 52, the rotating frame 53, the placing plate 54 and the limiting plate 55, when the motor 51 is started, the rotating plate 52 can be driven to rotate. The rotation of the rotating plate 52 drives the rotating frame 53 to move inward through the axle pin. The rotating frame 53 moves inward and drives the placing plate 54 and the limiting plate 55 to move inward. The limiting plate 55 moves inward to limit the bracket body 2 on the top of the bottom plate 1.

[0025] refer to Figure 1-4 As shown, the front and rear sides of the top of the rotating frame 53 are fixedly connected with stabilizing blocks 6, and the front and rear sides of the bottom of the bottom plate 1 are provided with stabilizing grooves 7, and the stabilizing blocks 6 and the stabilizing grooves 7 are slidably connected.

[0026] As a technical optimization solution of the utility model, the stabilizing block 6 and the stabilizing groove 7 cooperate with each other to limit the rotating frame 53, thereby preventing the rotating frame 53 from being separated from the rotating plate 52 during movement, thereby causing the rotating frame 53 to be unable to effectively drive the placement plate 54 and the limiting plate 55 to contact the bracket body 2, thereby causing the limiting plate 55 to be unable to effectively limit the bracket body 2.

[0027] refer to Figure 1-4 As shown, a circular sleeve 56 is fixedly connected to the inner wall of the limiting plate 55, a circular block 57 is slidably connected inside the circular sleeve 56, a circular rod 58 is fixedly connected to the inner side of the circular block 57, the inner end of the circular rod 58 passes through the inner side of the circular sleeve 56, a rubber pad 59 is fixedly connected to the inner side of the circular rod 58, and the inner side of the rubber pad 59 contacts the surface of the bracket body 2.

[0028] As a technical optimization scheme of the utility model, through the mutual cooperation of the circular sleeve 56, the round block 57, the round rod 58 and the rubber pad 59, the limiting plate 55 can move inward to drive the circular sleeve 56 to move inward, and the circular sleeve 56 moves inward to drive the round block 57, the round rod 58 and the rubber pad 59 to move inward. When the rubber pad 59 contacts the bracket body 2, since the surface of the bracket body 2 is not flat, the rubber pad 59 will contact the raised part of the bracket body 2, thereby driving the round rod 58 and the round block 57 to slide outward inside the circular sleeve 56, so that the rubber pad 59 will contact the bracket body 2, thereby improving the stability of the bracket body 2 when limiting.

[0029] refer to Figure 1-4 As shown, a spring 8 is sleeved on the surface of the round rod 58 , the inner end of the spring 8 is fixedly connected to the outer side of the round block 57 , and the outer end of the spring 8 is fixedly connected to the inner wall of the round sleeve 56 .

[0030] As a technical optimization solution of the utility model, by setting the spring 8, the round block 57 can always bear the elastic force of the spring 8, so that the round rod 58 and the rubber pad 59 can also always bear the elastic force of the spring 8, so that the rubber pad 59 and the bracket body 2 will automatically reset after separation.

[0031] refer to Figure 1-4 As shown, a protection box 9 is fixedly connected to the bottom of the base plate 1 , the motor 51 is located inside the protection box 9 , and heat dissipation grooves 10 are provided on the front and rear sides of the protection box 9 .

[0032] As a technical optimization solution of the utility model, the protection box 9 and the heat dissipation slot 10 cooperate with each other to protect the motor 51 and prevent foreign matter from entering the motor 51 and causing damage to the motor 51.

[0033] refer to Figure 1-4 As shown, the front side and the rear side of the top of the placement plate 54 are fixedly connected with reinforcing ribs 11 , and the inner side of the reinforcing ribs 11 and the front side and the rear side of the limiting plate 55 are fixedly connected.

[0034] As a technical optimization solution of the present invention, by providing reinforcing ribs 11, the limit plate 55 can be supported to prevent the inner top of the limit plate 55 from being clamped too much, thereby causing the bottom of the limit plate 55 to break.

[0035] The working principle and use process of the utility model are as follows: when in use, the user places the bracket body 2 on the top of the bottom plate 1. When the bracket body 2 needs to be moved, the user can start the motor 51 to drive the rotating plate 52 to rotate. The rotating plate 52 rotates and drives the rotating frame 53 to move inward through the axle pin. The rotating frame 53 moves inward to drive the placement plate 54 and the limiting plate 55 to move inward. The limiting plate 55 moves inward to drive the circular sleeve 56 to move inward. The circular sleeve 56 moves inward to drive the round block 57, the round rod 58 and the rubber pad 59 to move inward. When the rubber pad 59 contacts the bracket body 2, since the surface of the bracket body 2 is not flat, the rubber pad 59 will contact the raised part of the bracket body 2, thereby driving the round rod 58 and the round block 57 to slide outward inside the circular sleeve 56, so that the rubber pad 59 will all contact with the bracket body 2, so as to limit the position. Finally, the user can push the bottom plate 1 to move the bracket body 2 and move to the next step for processing.
