[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0026] Please see Figures 1-5 This utility model provides a technical solution:

[0027] A bearing machining anti-deformation fixture includes a base plate 1, a magnetic plate 2, a bearing body 3, and a drive assembly 4. The top of the base plate 1 is fixedly connected to the drive assembly 4 by bolts. A clamping assembly 5 is fixedly connected to one side of the drive assembly 4. The drive assembly 4 includes a housing 41, with a rail groove 42 formed on the inner side of the housing 41. A hydraulic rod 43 is fixedly connected to the inner side of the housing 41. A rail plate 44 is fixedly connected to one end of the hydraulic rod 43. A first toothed plate 45 is fixedly connected to one side of the rail plate 44. The clamping assembly 5 includes a steel sheet 51, with a vertical outer side of the steel sheet 51 fixedly connected to... A directional slider 52 is connected to a steel plate 51. A linear spring 54 is fixedly connected to the outer side of the steel plate 51. A second toothed plate 53 is fixedly connected to one side of the steel plate 51. A rubber sheet 55 is fixedly connected to the side of the steel plate 51 away from the second toothed plate 53. The directional slider 52 is embedded in the inner side of the limiting groove 58. The limiting groove 58 is opened on the inner side of the folding frame 57. A spring telescopic rod 56 is fixedly connected to one side of the folding frame 57. One side of the spring telescopic rod 56 is fixedly connected to one side of the rail plate 44. The bottom end of the housing 41 is fixedly connected to the top end of the base plate 1 by bolts.

[0028] As a further implementation of this solution, a magnetic plate 2 is fixedly connected to the top of the substrate 1. The upper end of the magnetic plate 2 is attached to the bottom end of the bearing body 3, and the outer side of the bearing body 3 is in close contact with one side of the rubber sheet 55. Through the above arrangement, the magnetic plate 2 plays the role of temporarily limiting the bearing. The diameter of the magnetic plate 2 is smaller than the outer diameter of the bearing body 3 and larger than the inner diameter of the bearing body 3, thus providing temporary support for the bearing body 3.

[0029] As a further implementation of this solution, there are multiple drive components 4, and the number of drive components 4 is the same as the number of clamping components 5. The clamping components 5 are partially embedded inside the drive components 4. Through the above arrangement, multiple drive components 4 and clamping components 5 can clamp the bearing body 3 in multiple directions, thereby improving the stability of clamping the bearing body 3.

[0030] As a further implementation of this solution, the rail groove 42 is shaped as a three-section rectangle. The rail groove 42 passes through one end of the housing 41. A fixing groove is provided on the inner side of the housing 41 near the hydraulic rod 43. Limiting sliders are fixedly connected to the left and right sides of the rail plate 44. The rail plate 44 is slidably connected to the inner side of the rail groove 42 opened in the housing 41. The first toothed plate 45 is fixed with teeth on one end near the clamping assembly 5. Two first toothed plates 45 are fixed on one side of the rail plate 44. One side of the first toothed plate 45 meshes with one side of the second toothed plate 53. The positions of the first toothed plate 45 and the second toothed plate 53 correspond one-to-one. With the above arrangement, the clamping assembly 5 can be driven to move stably towards the bearing body 3. Through the meshing between the first toothed plate 45 and the second toothed plate 53, the movement of the steel plate 51 can be prevented, thus fixing the position of the steel plate 51.

[0031] As a further implementation of this solution, the steel sheet 51 protrudes from the outer side of the housing 41, and the rubber sheet 55 has stripes on the end away from the steel sheet 51. Two second toothed plates 53 are fixed on one side of the steel sheet 51. Directional sliders 52 are fixed to the top and bottom of the steel sheet 51. The end of the linear spring 54 away from the second toothed plates 53 is fixedly connected to the inner side of the folding frame 57. Limiting grooves 58 are opened at the upper and lower ends of the folding frame 57. The side of the steel sheet 51 away from the second toothed plates 53 is flush with the side of the folding frame 57 away from the spring telescopic rod 56. Folding frames 57 are installed at both ends of the steel sheet 51. Through the above settings, the contact area with the outer side of the bearing body 3 can be increased, preventing the bearing body 3 from deforming when clamping the bearing body 3, improving the processing quality of the bearing body 3. At the same time, this clamping method does not require manual intervention, improving the safety during operation. It does not require replacement of the arc plate or other parts, thus greatly improving the flexibility and application range of the fixture.

[0032] Workflow: When clamping bearings of different diameters, the bearing body 3 is placed on the upper end of the magnetic plate 2. Simultaneously, multiple hydraulic rods 43 are activated to move the rail plate 44 towards the bearing body 3. The rail plate 44 is slidably connected to the inner side of the rail groove 42, limiting its movement. The rail plate 44 drives the first toothed plate 45 and the clamping assembly 5 to move towards the bearing body 3. When the rubber sheet 55 is in contact with the outer side of the bearing body 3, both the rubber sheet 55 and the steel sheet 51 deform. During the deformation of the rubber sheet 55, the steel sheet 51 drives the directional slider 52 to move. The directional slider 52 is slidably connected to the inner side of the limiting groove 58, limiting the movement of both ends of the steel sheet 51. Simultaneously, the steel sheet 51 drives two linear... Spring 54 extends to a certain extent. As the rail plate 44 and the first toothed plate 45 move continuously, multiple spring telescopic rods 56 retract simultaneously. When the first toothed plate 45 meshes with the second toothed plate 53, it fixes the positions of both ends of the steel sheet 51. At this time, it can clamp bearing bodies 3 of different diameters. This clamping method can not only use the outer diameter of the bearing body 3, but also increase the contact area with the outer side of the bearing body 3, preventing the bearing body 3 from deforming when clamping it, thus improving the processing quality of the bearing body 3. At the same time, this clamping method does not require manual intervention, improving the safety during operation. It does not require the replacement of the arc plate or other parts, thus greatly improving the flexibility and application range of the fixture.

[0033] When resetting the device, the hydraulic rod 43 is activated to move the rail plate 44 away from the bearing body 3. As the rubber sheet 55 gradually moves away from the bearing body 3, the spring extension rod 56 pushes the folding frame 57, steel sheet 51, and second toothed plate 53 away from the first toothed plate 45. After the first toothed plate 45 and the second toothed plate 53 move away from each other, the two linear springs 54 pull the steel sheet 51 into the folding frame 57, thereby restoring the shape of the steel sheet 51 and facilitating the clamping of the bearing body 3 again.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
