Anti-deformation special-shaped grinding wheel

Abstract

The invention discloses an anti-deformation special-shaped grinding wheel which comprises a base body and a grinding ring. Hollowed non-entity machining zones which do not participate in grinding are uniformly distributed on the special-shaped grinding surface of the grinding ring, and the other parts are served as entity machining zones which participate in grinding; the total circumferential line length of the entity machining zones at different axial positions corresponds to the machining allowance of parts to be machined at the same position, and the corresponding relation is direct proportion relation or similar to direct proportion relation, so that an equiform wearing structure of the special-shaped grinding surface is formed; a flow channel is manufactured inside the base body to be communicated with the non-entity machining zones; cooling water is injected into the base body through a water inlet of the base body and is applied to a grinding contact surface zone through the flow channel, so that an comprehensive cooling system which can ensure that a plurality of common external cooling type equipment can be conveniently converted into internal cooling type equipment is formed. The grinding wheel has the advantages that the deformation of the special-shaped grinding surface is small when the grinding wheel is operated, rapid cooling and rapid chip removal can be realized, the grinding wheel is applied to rapid and high-speed machining, the surface machining quality of work pieces is improved, the sharpness of the grinding wheel is kept, and the service life is prolonged.

Description

(1) Technical field: [0001] The invention relates to a grinding tool, in particular to an anti-deformation special-shaped grinding wheel. (two) background technology: [0002] The grinding of metal or non-metallic materials is done with grinding wheels. For plane processing, grinding wheels with a flat grinding surface (or a flat running track) are used, while for special-shaped edging processing, special-shaped grinding surfaces are often used. Grinding wheel. The shape of the special-shaped grinding surface of the grinding wheel corresponds to the corner shape requirements of the material. The commonly used corner shape of the final forming is arc, and there are other shapes besides the arc, such as regular geometric shapes, or straight lines, arcs, Irregular geometric shapes composed of line segments such as curves. [0003] For blanks with special-shaped edging, a machining allowance should be reserved, and the machining allowance is not reserved for the shape of the s...

Problems solved by technology

[0007] Due to the need to solve the layout of the internal cooling pipeline and the connection and sealing of the grinding wheel shaft and the water inlet and outlet of the grinding wheel central shaft hole, it is the reason for the complexity of the cooling mechanism of the internal cooling grinding machine, which in turn increases the manufacturing cost of the internal cooling grinding machine. Moreover, ordinary grinding wheels cannot be used on internally cooled grinding machines, and special grinding wheels with cooling structures must be used, resulting in an increase in the final comprehensive processing cost

[0008] In addition, no matter whether the ordinary grinding wheel is used on the external cooling grinding machine or the internal cooling grinding wheel is used on the internal cooling grinding machine, the grinding surface structure of the current technology determines that the threads brought out by the powder chips are large and the amount of limited

The discharge rate and amount of dust will directly affect the processing quality and efficiency. When the powder is difficult to be completely brought out, the processing quality and efficiency will be reduced. This is also the key to the inability to improve the working efficiency of the grinding wheel.
