Background
In order to facilitate processing, grinding wheels with different granularities are fixedly sleeved on the cutter bar from top to bottom and sequentially grind workpieces. As shown in fig. 1, since the water inlet of each grinding wheel is located at the top of the grinding wheel, after a plurality of grinding wheels are stacked on the cutter bar up and down, the water inlet of the next grinding wheel is blocked by the previous grinding wheel, so that water cannot be normally supplied to the next grinding wheel.
As shown in fig. 2, in order to overcome the technical problem that water cannot be normally supplied to the next grinding wheel, in the prior art, a gasket is additionally arranged between two adjacent grinding wheels, so that a space communicated with a water inlet of the next grinding wheel is formed between the two adjacent grinding wheels, and cooling water is further input to the water inlet of the next grinding wheel through the space. The mode of adding the gasket has the following defects:
1. the additional arrangement of the gasket can influence the assembly precision of the grinding wheel, so that the processing quality is reduced;
2. the water pipe for providing cooling water from the outside is positioned above the workpiece, and when the machined grinding wheel is replaced, the water pipe and the grinding wheel synchronously move up and down until the corresponding grinding wheel corresponds to the position of the workpiece. Therefore, the water pipe is far away from the water inlet of the grinding wheel below, and cooling water is not easy to enter the water storage cavity of the grinding wheel below.

Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 3 to 5, a grinding wheel base with a communication structure includes cover plates 1, bases 2, and screws 13. A plurality of bases 2 are fixedly sleeved on the cutter bar 3 in sequence from top to bottom respectively, the cover plates 1 are arranged in one-to-one correspondence with the bases 2, and the cover plates 1 are fixed above the corresponding bases 2. The cover plate 1 and the base 2 are correspondingly spliced with a plurality of tooth plates 4 in an annular mode at positions close to the periphery, the cover plate 1, the base 2 and the tooth plates 4 form a grinding wheel with a water storage cavity 5 inside, and the cover plate 1 is provided with an annular water inlet 6 communicated with the water storage cavity 5 correspondingly. A water trough 7 communicated with the corresponding water storage cavity 5 is arranged between every two adjacent tooth sheets 4. The base 2 of all the grinding wheels except the lowermost grinding wheel is provided with a water conveying mechanism, the water conveying mechanism sucks cooling water downwards into the corresponding water storage cavity 5 through the water inlet 6, and the water conveying mechanism also blocks the part of the cooling water flowing downwards in the corresponding water storage cavity 5, so that the part of the cooling water flows radially and is thrown out through the water through groove 7. The screw of the screw 13 passes through the cover plate 1 and then is fixedly connected to the corresponding base 2 downwards at the inner side of the tooth piece 4, so that the cover plate 1 presses the tooth piece 4 on the corresponding base 2.
The water delivery mechanism comprises a drain 8 and a plurality of vanes 9. The lower water gap 8 is annular and is located at a position corresponding to the bottom of the water storage cavity 5 on the base 2, the water inlet 6 and the lower water gap 8 of the same grinding wheel are arranged and communicated up and down oppositely, and the lower water gap 8 of the previous grinding wheel is opposite to the water inlet 6 of the next grinding wheel up and down, so that the water storage cavity 5 of the previous grinding wheel is communicated with the water storage cavity 5 of the next grinding wheel. The vanes 9 are uniformly arranged in the respective collector nozzle 8. The lower nozzle 8 of the next grinding wheel is smaller than the width of the lower nozzle 8 of the previous grinding wheel, and the lower nozzle 8 of the uppermost grinding wheel is smaller than the width of the water inlet 6 of the grinding wheel, i.e. L1＞L2＞L3……。
The upper end of the cutter bar 3 is fixedly connected with the lower end of a taper shank 11 through a flange 10. A sleeve is fixed on the cutter bar 3 at a position corresponding to a position between the flange 10 and the uppermost grinding wheel, and the sleeve is used for increasing the distance between the flange 10 and the water inlet 6 of the uppermost grinding wheel, so that the externally-sprayed cooling water is prevented from being blocked by the flange 10 and enters the corresponding water storage cavity 5 through the water inlet 6 of the uppermost grinding wheel. The sleeving part is a gasket 12, and the gasket 12 is fixedly sleeved on the cutter bar 3 at a position corresponding to the position between the flange 10 and the uppermost grinding wheel.
The external water pipe sprays cooling water to the water inlet 6 of the uppermost grinding wheel, and the gasket 12 increases the distance between the flange 10 and the water inlet 6 of the uppermost grinding wheel, so that a certain space is formed between the flange 6 and the water inlet 6 of the uppermost grinding wheel, and the external water pipe can spray cooling water towards the water inlet 6 of the uppermost grinding wheel through the space formed by the flange 6 and the water inlet 6 of the uppermost grinding wheel. In addition, the blade 9 is arranged in the lower water port 8 on the uppermost grinding wheel base 2, the blade 9 synchronously rotates in the process of processing rotation to form downward suction force, and under the action of the suction force, cooling water sprayed by an external water pipe is sucked into the water storage cavity 5 through the water inlet 6 of the uppermost grinding wheel, so that sufficient cooling water can enter the water storage cavity 9 of the uppermost grinding wheel through the water inlet 6 of the uppermost grinding wheel.
The cooling water entering the water storage cavity 9 of the uppermost grinding wheel is divided into two branches (indicated by arrows in fig. 3) because the lower water gap 8 of the uppermost grinding wheel is vertically opposite to the water inlet 6, and the lower water gap 8 of the uppermost grinding wheel is smaller than the width of the water inlet 6 of the uppermost grinding wheel:
the base 2 of the uppermost grinding wheel blocks part of the cooling water flowing downwards at a position close to the water inlet 6, the blocked cooling water flows in a radial direction to form first branch cooling water, and the first branch cooling water is finally thrown out of a water through groove 7 of the uppermost grinding wheel to a working surface under the action of centrifugal force;
the cooling water which is not blocked by the base 2 of the uppermost grinding wheel passes through the water outlet 8 under the suction force of the blade 9 to form a second branch cooling water, and the second branch cooling water finally enters the water storage cavity 5 of the next grinding wheel from the water inlet 6 of the next grinding wheel.
In the water storage cavity 5 of each grinding wheel, two branches of cooling water are formed according to the principle, if the base 2 of the grinding wheel cannot block part of the cooling water flowing downwards to form the first branch of cooling water, most of the cooling water flows downwards, and finally, the grinding wheel above the base has the defect of insufficient cooling water. When the cooling water reaches the lowest grinding wheel, because the base 2 of the lowest grinding wheel is not provided with a water conveying mechanism (a water outlet 8 and a blade 9), the cooling water entering the water storage cavity 5 of the lowest grinding wheel can be thrown out of the working surface through the corresponding water through groove 7 under the action of centrifugal force.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
