Description

Technical Field

[0001] The utility model relates to the technical field of grinding discs, in particular to a lower grinding disc with a radial heat dissipation structure. Background Art

[0002] The lower grinding disc generates a large amount of heat during high-speed grinding. If the heat is not dissipated in time, it may cause thermal deformation of the grinding disc, affecting machining accuracy and service life. Existing lower grinding discs mostly use a labyrinth-style cooling channel, where the coolant flows in from the outside, flows unidirectionally through a complex path within the disc, and then is discharged. However, the coolant flow resistance increases at the turns of the labyrinth-style channel, which easily forms flow dead zones and increases the risk of blockage. In addition, because the coolant gradually heats up along the long path, the local cooling effect decreases, which can easily lead to local overheating, thus affecting the grinding quality.

[0003] In order to solve the above problems, the utility model proposes a lower grinding disc with a radial heat dissipation structure to solve the above problems. Utility Model Content

[0004] The purpose of the present invention is to address the deficiencies of the prior art and provide a lower grinding disc with a radial heat dissipation structure to solve the problems raised in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lower grinding disc with a radial heat dissipation structure, comprising a disc body, an inner ring groove is provided at the center of the disc body, a circle of water inlet holes is evenly provided on the side wall of the inner ring groove, a cooling channel is provided in the disc body, the cooling channel is radially arranged in the disc body, the water inlet is connected with the cooling channel, a cooling channel processing hole connected with the cooling channel is provided at the outer edge of the disc body, a blocking wire is provided on the cooling channel processing hole, and a cooling channel lower water outlet connected with the cooling channel is provided on the lower side wall of the disc body.

[0006] Preferably, the number of the water inlet holes is equal to the number of the cooling channels.

[0007] Preferably, the number of the cooling channel processing holes, the cooling channel lower water outlets and the cooling channel is equal, that is, each cooling channel is provided with a cooling channel processing hole and a cooling channel lower water outlet.

[0008] Preferably, the cooling channel is a through hole provided in the disc body.

[0009] Preferably, the aperture of the cooling channel is enlarged in the latter half.

[0010] Preferably, each of the cooling channels is linear.

[0011] Preferably, there are 36 cooling channels in total, and the angle between every two adjacent cooling channels is 10°.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The radial cooling channel design allows the coolant to flow in from the center of the disk and flow radially outward, shortening the flow path. The aperture of the cooling channel increases in the latter half, increasing the cooling area and reducing the temperature rise of the coolant in the channel, thereby improving the overall cooling efficiency.

[0014] The coolant spreads evenly from the center outward through centrifugal force, reducing flow resistance and preventing local overheating, thereby ensuring a more uniform temperature distribution. BRIEF DESCRIPTION OF THE DRAWINGS
