Description

Technical Field

[0001] The utility model relates to the field of machinery, and specifically relates to a grinding wheel cooling device. Background Art

[0002] During the process of machining workpieces by traditional surface grinders, the heat generated during machining will be conducted into the grinding wheel base body, causing the size of the grinding wheel to change, thereby affecting the stability of the machining size of the workpiece. Existing grinding wheel cooling devices have certain deficiencies in terms of cooling effect, adjustability, and maintenance convenience. Content of the Utility Model

[0003] To solve the above problems, the utility model discloses a grinding wheel cooling device.

[0004] The specific technical solution is as follows: A grinding wheel cooling device is provided with a cooling disc. The cooling disc is fixed at the lower part of the surface grinding wheel by screws. A water distribution disc is connected to the lower end of the cooling disc. The surface grinding wheel is connected to a grinding wheel flange. The surface grinding wheel and the grinding wheel flange are jointly connected to a grinding wheel spindle to form an integral body. Through holes are provided inside the grinding wheel spindle and the grinding wheel flange to form a passage. A cavity is provided inside the surface grinding wheel. A gap is left between the cooling disc and the upper end of the cavity. A water distribution hole is provided in the middle of the cooling disc.

[0005] Studs are provided on both the cooling disc and the water distribution disc. The cooling disc and the water distribution disc are connected by the studs.

[0006] The outer edge of the water distribution disc is chamfered.

[0007] A diversion platform is provided at the center of the water distribution disc. The diversion platform is conical.

[0008] The advantages of the utility model are as follows: The water distribution hole provided at the center of the cooling disc divides the cooling water into two flow directions. One part is mainly used to cool the grinding wheel base body, and the other part is mainly used to cool and wash the surface of the grinding wheel, making the surface of the grinding wheel base body cooler more fully. The gap amount among the grinding wheel, the cooling disc, and the water distribution disc can be set as needed. The cooling disc and the water distribution disc can be quickly replaced.

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0014] A grinding wheel cooling device is provided with a cooling disk 4, and the cooling disk 4 is fixed to the lower part of the surface grinding wheel 3 by screws 6. A water distribution disk 5 is connected to the lower end of the cooling disk 4. The surface grinding wheel 3 is connected to a grinding wheel flange 2, and the surface grinding wheel 3 and the grinding wheel flange 2 are jointly connected to a grinding wheel spindle 1 to form an integral body. Through holes are provided inside the grinding wheel spindle 1 and the grinding wheel flange 2 to form a passage 1a, and a cavity 3a is provided inside the surface grinding wheel. A gap is left between the upper end portions inside the cooling disk 4 and the cavity 3a, and a water distribution hole is provided in the middle of the cooling disk 4.

[0015] Studs are provided on both the cooling disk 4 and the water distribution disk 5, and the cooling disk 4 and the water distribution disk 5 are connected by studs 7. The studs 7 are provided for connecting the cooling disk 4 and the water distribution disk 5. At the same time, setting three or more studs 7 can adjust the distance between the water distribution disk 5 and the cooling disk 4, thereby adjusting the water flow of the cooling water.

[0016] In order to make the water path of the cooling water smooth, the outer edge of the water distribution disk 5 is chamfered.

[0017] In order to quickly divide the cooling water flowing from top to bottom, a diversion platform 8 is provided at the center of the water distribution disk. The diversion platform 8 is conical or the shape of the diversion platform 8 can be a convex platform structure with a cross-sectional area gradually increasing from top to bottom, as long as a slope is set to change the water flow direction of the cooling water from vertical flow to horizontal flow.

[0018] The working principle of the present utility model is as follows: The grinding wheel spindle 1 drives the surface grinding wheel 3 to rotate. When rotating, the cooling water flowing in from the center of the spindle is divided into two parts by the central hole on the cooling disk 4. One part remains on the cooling disk 4 to cool the grinding wheel base, and the other part flows to the water distribution disk 5. Through the rotation of the grinding wheel spindle 1, the cooling water is thrown onto the inner end face of the surface grinding wheel to cool and wash the inner end face of the surface grinding wheel.

[0019] The sizes and gaps of the cooling disk 4 and the water distribution disk 5 can be designed according to the size and space of the surface grinding wheel, that is, by adjusting the studs, the distance between the cooling disk and the water distribution disk can be adjusted to achieve the maximum cooling effect.
