Description

Technical Field

[0001] The utility model relates to the technical field of diamond rollers, in particular to an assembled diamond roller. Background Art

[0002] In the production process of diamond rollers, the wheel base is usually processed first, and then the diamond particles are fixed to the surface of the wheel base by brazing or electroplating. Therefore, the surface structure of the wheel base determines the structure of the diamond roller, which is relatively restrictive.

[0003] In addition, the wheel base of the diamond roller generally adopts an integral structure. During use, if the diamond particles on the local surface of the wheel base fall off, the entire diamond roller will be scrapped. Because users usually do not have the conditions and technology to repair the diamond roller, they can only replace the entire roller, which is costly and wasteful, and needs to be improved.

[0016] The following combination Figures 1 and 2 The technical solution of the present utility model is further illustrated by specific embodiments.

[0017] like Figure 1 The assembled diamond roller shown includes: a wheel base mounting sleeve 1, a wheel base assembly and a ventilation pipe 2. An annular baffle 3 is concentrically arranged on the wheel base mounting sleeve 1. In this embodiment, the baffle 3 and the wheel base mounting sleeve 1 adopt an integrated steel structure with high strength.

[0018] The wheel base mounting sleeve 1 is provided with an array of ventilation holes 7 extending axially along the wheel base mounting sleeve 1 . The ventilation holes 7 can reduce the dead weight of the wheel base mounting sleeve 1 and also provide ventilation, thereby improving the heat dissipation effect of the wheel base mounting sleeve 1 .

[0019] like Figure 1 As shown, the wheel base assembly includes a first wheel base plate 11, a second wheel base plate 12 and a third wheel base plate 13 which are concentrically arranged in sequence in front of the front face of the baffle 3. The corresponding wheel base shape is formed by the different outer diameter specifications of the first wheel base plate 11, the second wheel base plate 12 and the third wheel base plate 13.

[0020] In this embodiment, the diameters of the inner holes 16 of the first wheel substrate 11 , the second wheel substrate 12 and the third wheel substrate 13 correspond to the outer diameter of the wheel base mounting sleeve 1 , ensuring the concentricity of the first wheel substrate 11 , the second wheel substrate 12 and the third wheel substrate 13 .

[0021] like Figure 2 As shown, a first diamond particle layer 8 is provided on the outer circumference of the first wheel substrate 11. The first diamond particle layer 8 is formed by fixing diamond particles on the outer circumference of the first wheel substrate 11 by brazing or electroplating. Similarly, a second diamond particle layer 9 is provided on the outer circumference of the second wheel substrate 12, and a third diamond particle layer 10 is provided on the outer circumference of the third wheel substrate 13. Figure 1 As shown, after the first wheel substrate 11, the second wheel substrate 12 and the third wheel substrate 13 are assembled, the first diamond particle layer 8, the second diamond particle layer 9 and the third diamond particle layer 10 are combined together and assembled into a specific shape, which is more flexible to use.

[0022] In addition, when the first diamond particle layer 8, the second diamond particle layer 9 or the third diamond particle layer 10 is partially damaged, the corresponding first wheel substrate 11, the second wheel substrate 12 or the third wheel substrate 13 can be replaced. The operation is simple and there is no need to scrap the entire layer, which reduces maintenance costs.

[0023] Positioning pins 18 are arranged at intervals on the front of the baffle 3, passing through the first wheel base plate 11 and the second wheel base plate 12 and extending to the third wheel base plate 13. In this embodiment, positioning blind holes 17 corresponding to the positioning pins 18 are concavely provided on the front of the baffle 3. The positioning pins 18 are welded and fixed on the positioning blind holes 17, with precise positioning and a firm structure after welding.

[0024] like Figure 2 As shown, positioning through holes 14 corresponding to positioning pins 18 are provided on the first wheel substrate 11, the second wheel substrate 12 and the third wheel substrate 13. The positioning of the first wheel substrate 11, the second wheel substrate 12 and the third wheel substrate 13 is achieved through the positioning pins 18. They rotate synchronously with the wheel base mounting sleeve 1 to avoid relative torsion of the first wheel substrate 11, the second wheel substrate 12 and the third wheel substrate 13, and have high structural stability.

[0025] A first insertion hole corresponding to the ventilation pipe 2 is provided in a circular array on the baffle 3. The ventilation pipe 2 is arranged in the first insertion hole and passes through the first wheel substrate 11, the second wheel substrate 12 and the third wheel substrate 13. A retaining ring 4 is provided at the tail end of the ventilation pipe 2 on the back side of the baffle 3 to limit the axial position of the ventilation pipe 2 and ensure structural stability.

[0026] In this embodiment, the first wheel substrate 11, the second wheel substrate 12 and the third wheel substrate 13 are provided with second jacks 15 corresponding to the ventilation pipe 2, which facilitates assembly. The ventilation pipe 2 further improves the structural stability of the first wheel substrate 11, the second wheel substrate 12 and the third wheel substrate 13 after assembly, and the ventilation pipe 2 can be ventilated for air cooling, thereby improving the air cooling effect of the first wheel substrate 11, the second wheel substrate 12 and the third wheel substrate 13 after assembly.

[0027] In addition, the ventilation pipe 2 can be made of a copper pipe, which has a good heat conduction effect and is beneficial to the heat dissipation of the first wheel substrate 11, the second wheel substrate 12 and the third wheel substrate 13 during operation.

[0028] A nut 6 is provided on the ventilation pipe 2 in front of the third wheel substrate 6. Figure 1 As shown, the ventilation pipe 2 is provided with a gasket 5 located between the third wheel substrate 13 and the nut 6. The ventilation pipe 2 is provided with an external thread corresponding to the nut 6 to facilitate the disassembly and assembly of the nut 6. The gasket 5 is pressed by the nut 6 to tighten the third wheel substrate 6 by using the gasket 5 to prevent the first wheel substrate 11, the second wheel substrate 12 and the third wheel substrate 13 from loosening.

[0029] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
