[0002] A ball mill is a key device for crushing materials and then pulverizing them. It is widely used in production industries such as cement, silicate products, new building materials, refractories, fertilizers, non-ferrous metal beneficiation, and glass ceramics, for dry or wet grinding of various ores and other grindable materials. The working principle of the ball mill is mainly through the rotation of the cylinder body, so that the grinding media in the cylinder, such as steel balls, impact and grind the materials under the action of inertia and centrifugal force, so as to achieve the purpose of pulverization.

[0003] As a key supporting component of the ball mill, the quality and machining accuracy of the ball base directly affect the overall performance and stability of the ball mill; the main function of the ball base is to support and fix the cylinder body, ensure that the cylinder body can run smoothly during rotation, and at the same time withstand the impact and wear from the grinding media and materials. At present, when processing the ball base, the fixing method adopted is to directly fix the lower end surface of the ball base on the support seat through a fixture, and by changing the angle of the processing tool, process the surface to be processed of the ball base. It is necessary to frequently change the processing tool, which not only affects the processing efficiency, but also has low processing accuracy and cannot meet the requirements in actual use. Therefore, there is an urgent need for improved technology in the market to solve the above problems. Content of the Utility Model

Through the tooling, the surface to be processed of the ball base can be kept parallel to the bottom plate, and the inclined surface of the product can be cooperated with the processing tool for processing, without changing the angle of the processing tool, improving the processing quality and processing efficiency, and effectively solving the problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A fine machining tool for a ball base of a ball mill, including a bottom plate, a T-shaped vertical plate, a connecting plate and a tightening assembly. T-shaped vertical plates are symmetrically arranged on the left side of the upper surface of the bottom plate. An inclined surface one is arranged on the upper surface of the T-shaped vertical plate. A T-shaped inclined plate is arranged on this inclined surface one. A limiting groove is arranged on the lower surface of the T-shaped inclined plate, and the limiting groove is stuck on the inclined surface of the T-shaped vertical plate. The upper surface of the T-shaped inclined plate is set as an inclined surface two, and the included angle between the inclined surface two and the horizontal plane is greater than the included angle between the inclined surface one and the horizontal plane. A top block is arranged on the upper surface of the bottom plate. Tightening assemblies are respectively arranged on the outer side surface of the T-shaped vertical plate and the front and rear side surfaces on the right side of the bottom plate. The tightening assembly includes a tightening seat, a threaded ejector rod is threadedly connected to the tightening seat, and the inner end of the threaded ejector rod is rotatably connected with a tightening disc.

[0006] Further, the T-shaped vertical plates are fixedly connected by a connecting plate, and lifting lugs are respectively arranged on the left and right side surfaces of the bottom plate.

[0007] Further, four tightening assemblies are provided, with two in a group. The height of the left tightening assembly is higher than that of the right tightening assembly.

[0008] Further, a first side plate is arranged on the outer side surface of the T-shaped vertical plate, and second side plates are respectively arranged on the front and rear side surfaces of the right side of the bottom plate.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] 1. The tooling can keep the surface to be machined of the ball base parallel to the bottom plate, and the inclined surface of the product can cooperate with the machining tool for machining without the machining tool changing the angle, improving the machining quality and efficiency.

[0011] 2.

[0012] 3. Through this tooling, the overall performance and stability of the ball mill reach the most reasonable state of design, with higher working efficiency. Compared with the traditional tooling fixing method, it can better guarantee the product quality, thus saving the production and manufacturing cost, improving the production and delivery cycle of the ball mill, and satisfying the customers.

Specific implementation manner

[0019] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0020] Please refer to Figures 1-5 , the present utility model provides a technical solution: a fine machining tooling for the ball base of a ball mill, including a bottom plate 9, a T-shaped vertical plate 2, a connecting plate 3 and a tightening assembly. T-shaped vertical plates 2 are symmetrically arranged on the left side of the upper surface of the bottom plate 9. The upper surface of the T-shaped vertical plate 2 is provided with a first inclined surface 13, and the first inclined surface 13 contacts the inclined surface of the ball base 14 to play a supporting role. A T-shaped inclined plate 15 is arranged on the first inclined surface 13. The lower surface of the T-shaped inclined plate 15 is provided with a limiting groove 16, and the limiting groove 16 is stuck on the inclined surface of the T-shaped vertical plate 2. The upper surface of the T-shaped inclined plate 15 is set as a second inclined surface 17, and the angle between the second inclined surface 17 and the horizontal plane is greater than the angle between the first inclined surface 13 and the horizontal plane. The first inclined surface 13 can meet the fixing requirements of the ball base 14 with a conventional structure. When the ball base 14 changes, the fixing requirements of different specifications of the ball base 14 can be met by adding a T-shaped inclined plate 15 and changing the inclination angle, that is, through the second inclined surface 17. A top block 7 is arranged on the upper surface of the bottom plate 9, and the top block 7 plays a role in restricting the lower end of the ball base 14 to prevent the ball base 14 from sliding on the inclined surface. Tightening assemblies are respectively arranged on the outer side surface of the T-shaped vertical plate 2 and the front and rear side surfaces on the right side of the bottom plate 9. The tightening assembly includes a tightening seat 10, a threaded ejector rod 11 is threadedly connected to the tightening seat 10, and the inner end of the threaded ejector rod 11 is rotatably connected with a tightening disc 12. By turning the threaded ejector rod 11 with a wrench, the threaded ejector rod 11 moves inward under the action of the thread, and the ball base 14 is firmly fixed through the tightening disc 12.

[0021] The T-shaped vertical plates 2 are fixedly connected through the connecting plate 3. The T-shaped vertical plates 2 are reliably connected together through the connecting plate 3, improving the pressure-bearing capacity of the T-shaped vertical plates 2 and at the same time reducing the probability of deformation of the T-shaped vertical plates 2. Lifting lugs 8 are respectively arranged on the left and right end side surfaces of the bottom plate 9, and the lifting lugs 8 are used to lift the device for easy transportation.

[0022] The tightening components are set to four, with two as a group. The position height of the tightening components on the left is higher than that of the tightening components on the right.

[0023] A first side plate 1 is arranged on the outer side surface of the T-shaped vertical plate 2. The front and rear side surfaces on the right side of the bottom plate 9 are respectively provided with second side plates 5. The tightening seats 10 are fixed on the first side plate 1 and the second side plates 5. Adjusting holes 4 for fixing the tightening seats 10 are respectively arranged on the first side plate 1 and the second side plates 5. The adjusting holes 4 are arranged at equal intervals. The tightening seats 10 are fixedly connected with the tightening seats 10 through adjusting screws 6. By loosening the adjusting screws 6, the position of the tightening seats 10 on the side plates can be changed, and then the distance between the tightening seats 10 can be adjusted to meet the fixing requirements of ball bases 14 of different specifications.

[0024] During use: Place the ball base 14 on the first inclined surface 13 so that the lower end of the base 14 abuts against the top block 7. Rotate the threaded ejector rod 11 with a wrench. The inner end of the threaded ejector rod 11 abuts against the side surface of the ball base 14 through the tightening disc 12. The four tightening components firmly fix the ball base 14 on the tooling. Wait until the inclined surface of the ball base 14 is parallel and matched with the bottom plate 9, and then perform precision turning.
