Abstract

The utility model discloses a grinding disc device, comprising a grinding disc, a shaft end retaining ring, a double-cone sleeve pad between discs and a shaft. A plurality of grinding discs are staggerly distributed and sleeve the shaft. The double-cone sleeve pad between discs is disposed between two adjacent grinding discs. The shaft end retaining ring is disposed at the tail end of the shaft. The grinding disc is Delta-shaped, and two adjacent grinding discs are arranged in an angle of 30 DEG. More than two grinding discs can form a set according to the angle with each two grinding discs are arranged at interval. The grinding disc device is advantageous in that the grinding efficiency is high; the grinding process has axial and radial grindings, which greatly improves the grinding efficiency; as the grinding disc is Delta-shaped, materials are saved, weight is reduced and load to the shaft and machine vibration are reduced; as linear velocity at the waist position of the disc which is also the long arc of the contour is decreased, wearing is greatly declined.

Description

The abrasive disk device

Technical field

The utility model belongs to the surface of the work milling tool, is specifically related to a kind of abrasive disk device.

Background technology

Grinder is that a kind of high efficiency superfine grinding of production nano material disperses machinery, and abrasive disk is the core component of agitation grinding.Existing abrasive disk generally adopts circular design, on card, opens assisted millings such as groove miscellaneous or hole, and not only easy to wear, efficient is low, when rotating at a high speed, also is prone to vibrations.

Summary of the invention

In order to overcome the problems referred to above that the prior art field exists, the purpose of the utility model is, a kind of abrasive disk device is provided, and improves grinding efficiency, reduces wear extent, saves material.

The abrasive disk device that the utility model provides; It comprises pad between abrasive disk, shaft end ring, bipyramid sleeve dish, axle; Some abrasive disks are interspersed and are sleeved on the axle, and pad is arranged between adjacent two abrasive disks between bipyramid sleeve dish, and shaft end ring is arranged on the tip of the axis.Be uniform-distribution with three macropores and three apertures on the said abrasive disk card, macropore and aperture distribute alternately.Three less pitch-rows are nearer from the center of circle, also can be distributed on the circle of same size for the big aperture of disc of minor diameter.

Said abrasive disk be shaped as the delta type that english equivalents is DELTA, be 30 ° of angle between adjacent two abrasive disks, two above discs can be formed a cover according to this angle, per two dishes are spaced intermediate.Three macropores on each abrasive disk are positioned at the position at three angles, and aperture is evenly distributed between macropore.

The device that the utility model provides, its beneficial effect are that this abrasive disk device grinding efficient is high; And in process of lapping, have concurrently axial and radially grinding, improved grinding efficiency greatly, the design of DELTA type; Saved material, reduced weight, reduced the load of axle and the vibration of machine; Pan Yaochu is that the linear velocity of the oval arc of profile is lower, and wear extent significantly reduces.

Mark among the figure:

1. abrasive disk; 2. shaft end ring; 3. sunk screw; 4. fill up between bipyramid sleeve dish; The axle.

The specific embodiment

With reference to the accompanying drawings, in conjunction with an embodiment, the abrasive disk device to the utility model provides carries out detailed explanation.

Embodiment

With reference to Fig. 1-Fig. 3; The abrasive disk device of present embodiment; It comprises fill up 4 between abrasive disk 1, shaft end ring 2, sunk screw 3, bipyramid sleeve dish, axle 5, some abrasive disks 1 are interspersed and are sleeved on the axle 5, pad 4 is arranged between adjacent two abrasive disks between bipyramid sleeve dish; Shaft end ring 2 is arranged on the end of axle 5, connects fixing by sunk screw 3.Be uniform-distribution with three macropores and three apertures on the said abrasive disk card, macropore and aperture distribute alternately.Three less pitch-rows are nearer from the center of circle.

Said abrasive disk is that english equivalents is the delta type of DELTA.The typing of abrasive disk DELTA type dish: the maximum outside diameter of dish is made as D, and the point of the D/3 that then upwards squints from the center of circle is another center of circle, and is that radius is done circular arc with 3/4D, and circular arc and great circle are connected the enclose inside figure of formation mutually.The diameter of macropore is about keyway edge half the to the top edge distance, and is in the centre position of outer edge, and three holes are uniformly distributed with; Bore edges was to half of lower limb distance in the diameter of aperture was about, and was in the centre position of outer edge, and three holes are uniformly distributed with.Five abrasive disks are angle, and two above discs can be formed a cover according to this angle, and per two dishes are spaced intermediate.Three macropores on each abrasive disk are positioned at the position at three angles, and aperture is evenly distributed between macropore.

Claims

1. abrasive disk device; It is characterized in that: it comprises pad between abrasive disk, shaft end ring, bipyramid sleeve dish, axle; Some abrasive disks are interspersed and are sleeved on the axle, and pad is arranged between adjacent two abrasive disks between bipyramid sleeve dish, and shaft end ring is arranged on the tip of the axis.

2. abrasive disk device according to claim 1 is characterized in that: be uniform-distribution with three macropores and three apertures on the said abrasive disk card, macropore and aperture distribute alternately.

3. abrasive disk device according to claim 1 is characterized in that: said abrasive disk be shaped as the delta type that english equivalents is DELTA, be 30 ° of angle between adjacent two abrasive disks.
