Description

Technical Field

[0001] The utility model relates to the field of grinding wheel processing, in particular to a grinding wheel for chamfering inside a cylindrical tube shell. Background Art

[0002] Ceramic materials are made of ceramic blanks through high-temperature sintering. They generally have the characteristics of high strength, high density, and high wear resistance. Ceramic materials undergo physical and chemical reactions during the high-temperature sintering process, causing changes in their composition, performance, strength, etc., and are also accompanied by shrinkage in their external dimensions. Cylindrical ceramic materials shrink in size during the high-temperature sintering process, causing slight deformation of the ceramic, making the inner diameter of the cylindrical shell ceramic irregular and circular.

[0003] In order to solve the problem that the inner diameter of the cylindrical ceramic shell is irregular and circular, chamfering is generally used. The existing chamfering technology mainly uses three grippers on a lathe to add ceramic products, and then grinds them by hand with a file or by a universal cylindrical grinder using a rod-shaped grinding wheel. However, manual grinding is inefficient, labor-intensive, and has certain safety hazards. The grinding method using a rod-shaped grinding wheel on a grinder will cause uneven chamfering.

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0022] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0024] like Figure 1 and Figure 2As shown, the utility model is a grinding wheel for chamfering inside a cylindrical tube shell, comprising a grinding wheel body 1, which is in a truncated cone shape; a protrusion 3, wherein the protrusion 3 is multiple, the multiple protrusions 3 are arranged at intervals on the side wall of the grinding wheel body 1, and the protrusions 3 are evenly distributed along the circumference of the grinding wheel body 1; and a groove, wherein grooves 4 are provided between the protrusions 3.

[0025] The grinding wheel body 1 of this embodiment is preferably made of diamond resin, which can ensure that ceramic parts can be easily ground without causing bumps to the ceramics. The side wall of the grinding wheel body 1 is the outer curved surface of a truncated cone structure, and the evenly arranged protrusions 3 can grind cylindrical ceramics. The device is extended into the irregular concave part of the cylindrical ceramic for rotational grinding, which can achieve the effect of uniformly processing the inner chamfer.

[0026] The angle R formed between the side and bottom of the grinding wheel body 1 satisfies: 30°≤R≤60°. R is 45°. The preferred size of the angle α between the side and bottom of the grinding wheel body 1 of this embodiment is 45° or 30°≤α≤60°, and the multiple angle designs are suitable for use in multiple scenarios.

[0027] One end of the protrusion 3 extends to the top of the grinding wheel body 1, and the other end extends to the bottom of the grinding wheel body 1. The surface of the protrusion 3 is the grinding wheel surface. Figure 2 As shown, the present embodiment has 8 protrusions 3, but it is not limited thereto, and may also have 6 or 10 protrusions. The grinding wheel surface provided on the surface of each protrusion 3 can grind the irregular circles on the cylindrical ceramic to further ensure the grinding quality.

[0028] The groove is an arc-shaped groove. Figure 2 As shown, the groove is an arc-shaped groove. The arc-shaped groove can prevent the debris generated by the grinding wheel during grinding from being easily adhered and accumulated in the grinding wheel, making the grinding wheel easier to clean.

[0029] The grinding wheel body 1 is also provided with a rotating shaft 2, and the rotating shaft 2 is connected to the grinding wheel body 1. The grinding wheel handle is detachably connected to the grinding wheel body 1, or is integrally connected. In this embodiment, the grinding wheel body 1 is detachably connected to the rotating shaft 2, which makes it easier to replace the grinding wheel body 1 during use. Therefore, on the one hand, the grinding wheel body 1 of different specifications can be replaced during the grinding process to meet different grinding process requirements, which is convenient for improving the grinding quality and grinding efficiency. On the other hand, when the grinding wheel body 1 is damaged, the grinding wheel body 1 can be replaced independently, thereby reducing the use cost of the grinding wheel substrate and thus reducing the production cost.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
