Description

High-efficient abrasive disc

Technical Field

The utility model relates to an equipment technical field that mills specifically is a high-efficient abrasive disc.

Background

The abrasive disk is a carrier for coating or embedding an abrasive material so that the abrasive particles perform a cutting function and also a shaping tool for grinding a surface. Rotatable discs, cylinders, cones, plates, oilstones, sheets, tubes, rings, and specially shaped abrasive discs are all useful as abrasive tools.

The grinding disc of the grinding disc and the workpiece are mutually trimmed in the grinding process, and the geometric precision of the grinding disc is transferred to the workpiece to a certain degree, so that the processing surface of the grinding disc is required to have high geometric precision.

The main requirements for the grinding disc are:

(1) the hardness of the material is generally lower than that of a workpiece material, the structure is uniform and compact, impurities, foreign matters, cracks and defects do not exist, and the material has certain abrasive embedding humanity and soaking performance.

(2) Reasonable structure, good rigidity, precision retentivity and wear resistance. The working surface should have a high geometric accuracy.

(3) The chip removal performance and the heat dissipation performance are good.

The traditional grinding disc is easy to generate abrasive particle accumulation and damage to the surface of a workpiece in the using process, and simultaneously generates a large amount of heat to be sintered into thin blocks.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

In order to solve the above problem of the prior art, the utility model provides a high-efficient grinding disk solves traditional grinding disk and takes place the grit easily at the in-process that uses and pile up, harm workpiece surface, produces the problem that a large amount of heats sintered into the thin piece simultaneously.

(II) technical scheme

In order to achieve the above object, the utility model discloses a main technical scheme include:

the utility model provides a high-efficient abrasive disc, includes the disk body, a plurality of standing grooves have been seted up to angles such as disk body, the inside grinding roller that is provided with of standing groove, grinding roller middle part axis of rotation both ends fixedly connected with slider, standing groove upper portion open position is provided with sealed lid, the position still is provided with the spring between sealed lid and the slider, sealed lid still are provided with the locating pin with spring coupling department, the shaft hole has been seted up at the disk body middle part.

Preferably, the bottom of the grinding roller is positioned on one side below the disc body.

Preferably, the milling rollers are equiangularly arranged in six.

Preferably, the sealing cover and the tray body are fixedly connected through an inner hexagon bolt.

Preferably, the grinding roller is connected with a middle rotating shaft through a bearing.

Preferably, the grinding roller is of a frustum structure, and the diameter of the grinding roller close to the shaft hole is smaller than that of the grinding roller on the opposite side.

(III) advantageous effects

The utility model provides a high-efficient abrasive disc. The method has the following beneficial effects:

(1) the inside grinding roller that sets up of standing groove seted up through the disk body below, smash the time of milling to the material, apply external force to the grinding disk body, the roller of milling can carry out primary crushing to the material, continuously increase external force, make grinding roller bottom and disk body bottom be located same water flat line time, grinding roller and grinding table all mill the material, when meetting the grit and piling up, the roller of milling can overcome the elasticity of spring and upwards rise, avoid the damage of workpiece surface, reduce thermal piling up simultaneously.
