[0007] As an improvement, the number of the support plates is four, and the number of the slip rings is two.

[0008] As an improvement, the bidirectional lead screw passes through the base and is rotatably connected to the base. A second hand wheel is provided at one end of the bidirectional lead screw, and a screw is threadedly connected to the second hand wheel.

[0009] As an improvement, the fixing frame includes an integrally formed fixing plate and a fixing bar, the fixing bar passes through the base, and the fixing bar is slidably connected to the supporting plate.

[0010] As an improvement, the longitudinal section of the fixing strip is T-shaped, and the longitudinal section of the fixing plate is L-shaped.

[0011] As an improvement, the two ends of the slide seat are respectively in the shape of a quadrangular column and a quadrangular pyramid.

[0019] The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0020] A roller ring outer circle processing fixture comprises a base 1, a limiting component and an adjusting component are connected to the base 1, the limiting component comprises a slide 8 slidably connected to the base 1, four supporting plates 7 slidably connected to the slide 8, a plurality of fixing frames 3 slidably connected to the supporting plates 7, and a screw 10 threadedly connected to the slide 8, the slide 8 is provided with a plurality of inclined grooves 11 slidably connected to the supporting plates 7, the fixing frame 3 comprises an integrally formed fixing plate and a fixing bar, the fixing bar passes through the base 1, the fixing bar is slidably connected to the supporting plates 7, the fixing bar has a T-shaped longitudinal section, the fixing plate has an L-shaped longitudinal section, and the two ends of the slide 8 are respectively in the shape of a quadrangular prism and a quadrangular pyramid;

[0021] A driving assembly is provided between the screw 10 and the base 1, and the driving assembly includes a worm wheel connected to the screw 10, a worm 9 penetrating the base 1 and rotatably connected to the base 1, the worm 9 is meshed with the worm wheel, and the screw 10 is rotatably connected to the base 1. A first hand wheel 4 is provided at one end of the worm 9 to facilitate the rotation of the worm 9;

[0022] The adjustment assembly includes two slip rings 2 that are slidably connected to the base 1, and a bidirectional lead screw 12 that is threadedly connected to the slip ring 2. The slip rings 2 are located at both ends of the bidirectional lead screw 12. The fixing frame 3 passes through the slip ring 2 and is slidably connected to the slip ring 2. The bidirectional lead screw 12 passes through the base 1 and is rotatably connected to the base 1. A second hand wheel 5 is provided at one end of the bidirectional lead screw 12, and a screw 6 is threadedly connected to the second hand wheel 5.

[0023] Working principle: Figure 1 As shown, the base is connected to the roller ring external cylindrical processing machine, and then the roller ring is sleeved on the base;

[0024] like Figure 4 As shown, the bidirectional lead screw 12 is rotated by the second hand wheel 5, the bidirectional lead screw 12 drives the two slip rings 2 to move, and the slip ring 2 drives the fixed frame 3 to move horizontally along the support plate 7 until the roller ring can be directly lifted by the horizontal right-angle edge of the fixed plate on the fixed frame 3, and only a 1-2mm gap is left between the roller ring and the vertical right-angle edge of the fixed plate on the fixed frame 3, and then the screw 6 is tightened to make it abut against the base 1 to prevent the second hand wheel 5 from rotating by itself;

[0025] like Figure 3 As shown, by rotating the first hand wheel 4, the worm 9 drives the worm wheel to rotate, and the worm wheel moves the slide 8 to the right through the screw 10. The slide 8 squeezes the support plate 7 through the inclined groove 11 to push the fixed frame 3 to move. The eight fixed frames 3 expand outward from the base 1 at the same time so that they all abut against the inner side of the roller ring to fix it. The L-shaped fixing plate can limit the two ends of the roller ring to prevent it from flying out during external circle processing. It has good safety and will not affect the processing of the external circle. Due to the unidirectional transmission of the worm wheel and worm 9, the worm wheel can be prevented from rotating by itself, and the outer circle of the roller ring can be processed in cooperation with the roller ring external circle processing machine.

[0026] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
