Description

Technical Field

[0001] The present invention relates to a diamond roller, and in particular to a diamond roller with a heat dissipation structure applied in the technical field of diamond rollers. Background Art

[0002] Diamond rollers are usually installed on the dressing device of a grinder to perform large-scale shaping grinding of workpieces. The outer contour, accuracy and size of the diamond roller are copied to the surface of the part being processed through the grinding wheel. When the diamond roller is working, it is in constant friction contact with the workpiece to be ground, causing severe heating on it.

[0003] The specification of Chinese invention patent CN202222543396.7 discloses "A high heat dissipation diamond roller". When the surface of the workpiece is ground by the set flat grinding surface, the temperature of the flat grinding surface will increase, and the heat generated by the flat grinding surface will be transmitted to the heat conductive ring, and then the heat conductive ring will transfer the heat to the heat conductive strip B. The heat inside the heat conductive strip B will be transmitted to the cooling water inside the cooling water chamber, and then absorbed by the cooling water, and the flat grinding surface will be dissipated. Heat is dissipated in time and will not affect the surface quality of the workpiece.

[0004] Most existing diamond rollers adopt air cooling and water cooling in the above patent. The cooling efficiency of air cooling is lower than that of water cooling, but water cooling requires continuous replacement of cooling water, and the consumption of cooling water is huge, which affects the production cost of machine tools. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the heat dissipation efficiency of air-cooling is lower than that of water-cooling, and the consumption of cooling water of water-cooling is huge, which affects the production cost of the machine tool.

[0006] In order to solve the above problems, the present invention provides a diamond roller with a heat dissipation structure, comprising a roller ring body, the outer ring of the roller ring body is fixedly connected with a friction ring, the inner ring of the roller ring body is provided with a water cooling groove, the inside of the water cooling groove is fixedly connected with an evaporation circle leaf, and both ends of the outside of the water cooling groove are fixedly connected with external radiating leaves;

[0007] One end of the roller ring body is rotatably connected to a heat dissipation ring, the bottom of the heat dissipation ring is fixedly connected to a bracket plate, the end of the bracket plate is fixedly connected to a water covering plate, the water covering plate is movably connected to the water cooling tank, and both ends of the water covering plate are provided with passage grooves corresponding to the movement of the evaporation circle leaf;

[0008] The top two ends of the heat dissipation ring are fixedly connected with an air inlet duct and an exhaust duct respectively, the inner ends of the air inlet duct and the exhaust duct are fixedly connected with a wind bin, and the outer ends of the air inlet duct and the exhaust duct are fixedly connected with an induced draft fan, and the opening of the wind bin faces the evaporation circle.

[0009] In the above-mentioned diamond roller with heat dissipation structure, by retaining a proper amount of cooling water at the bottom of the water-cooling groove, a layer of cooling water quickly adheres to the surface of the evaporation circle during the rotation of the roller ring. Through the rapid drying and evaporation of the cooling water, efficient heat dissipation of the diamond roller is achieved, and the consumption of cooling water is effectively reduced.

[0010] As a further improvement of the present application, the left and right ends of the bracket plate are respectively fixedly connected with a water inlet pipe and a drain pipe, both of which pass through the water-covering plate. An appropriate amount of cooling water is added to the water-cooling trough at the bottom of the water-covering plate through the water inlet pipe, and excess cooling water is discharged through the drain pipe.

[0011] As a further improvement of the present application, the bottom inner ends of the water inlet pipe and the drain pipe are fixedly connected with vertical pipes, and the length of the vertical pipe on the water inlet pipe is greater than that of the vertical pipe on the drain pipe. A water level sensor and a temperature sensor are fixedly connected to the middle part of the bottom end surface of the water covering plate. The longer vertical pipe allows new cooling water to be directly delivered to the bottom of the water cooling tank, and the water level sensor and the temperature sensor are used to detect the usage of the cooling water, so as to accurately replace the new cooling water.

[0012] As a further improvement of the present application, wiping pads are provided at both ends of the bottom of the water-covering plate, grooves are provided on the surface of the wiping pads corresponding to the passage grooves, and the wiping pads are made of sponge material. The cooling water is wiped to the surface of the evaporator page through the wiping pads, while preventing the evaporator page from carrying excess cooling water over the passage groove.

[0013] As another improvement of the present application, a water sealing strip is fixedly connected between the left and right ends of the two water wiping pads. The water sealing strip corresponds to the inner wall of the water cooling groove. The water sealing strip is used to prevent cooling water from overflowing from the left and right ends of the water covering plate.

[0014] As another improvement supplement of the present application, a water collection groove is provided on the upper surface of the water covering plate, the top end of the water sealing strip extends out of the upper surface of the water covering plate, the water collection groove is parallel to the water sealing strip, and a reflux hole is provided at the bottom of the water collection groove. The cooling water falling on the water covering plate is collected by the water collection groove and returns to the water cooling groove through the reflux hole, thereby effectively preventing the cooling water from leaking from the diamond roller.

[0015] As another improvement supplement to the present application, a seepage column is fixedly inserted inside the reflux hole. The seepage column is made of sponge material. The reflux hole is blocked by the seepage column to effectively prevent the water in the water cooling tank from passing through the reflux hole in reverse, and the cooling water in the water accumulation tank can provide the seepage column to infiltrate back into the water cooling tank.

[0016] As another improvement of the present application, an assembly flange is fixedly connected to one end of the roller ring body away from the heat dissipation ring, and an inner ring tube is fixedly connected to the inside of the assembly flange. The inner ring tube is sleeved with the heat dissipation ring. The assembly flange and the inner ring tube facilitate the installation and fixation of the diamond roller and effectively improve the installation stability of the heat dissipation ring.

[0017] As another improvement supplement of the present application, an annular groove is opened at the outer middle end of the inner ring tube, and the annular groove corresponds to the same plane as the water cooling groove. The water falling on the surface of the inner ring tube is concentrated in the annular groove, which effectively prevents the cooling water on the surface of the inner ring tube from being carried out of the diamond roller, thereby effectively reducing the influence of the leaked cooling water on the processing of the workpiece.

[0018] As another improvement supplement of the present application, the surface of the annular groove is equidistantly arranged with blocking ribs, and the outside of the blocking ribs is fixedly connected with water-throwing ribs. The cooling water on the surface of the inner ring tube is blocked by the blocking ribs and then thrown off by the water-throwing ribs, which effectively reduces the residence time of the cooling water in the annular groove, thereby further effectively preventing the cooling water on the surface of the inner ring tube from being carried out of the diamond roller.

[0019] In summary, the present invention opens a water cooling groove in the inner ring of the roller ring body, and stores an appropriate amount of cooling water at the bottom of the water cooling groove. During the rotation of the roller ring body, the cooling water at the bottom of the water cooling groove remains relatively unchanged due to the influence of gravity, and the water covering plate covers the cooling water, which effectively reduces the influence of the rotation force of the evaporation circle on the cooling water, effectively prevents the cooling water from overflowing the water cooling groove, and thus avoids the cooling water from leaking from the diamond roller. The evaporation circle will circulate through the cooling water, so that a layer of cooling water is quickly attached to the surface of the evaporation circle and other positions of the water cooling groove. Subsequently, the air circulation inside the water cooling groove is strengthened through the air inlet and exhaust ducts, so that the cooling water is quickly dried and evaporated, which is convenient for the water vapor to carry heat and quickly discharge it from the diamond roller, effectively improving the heat dissipation effect of the diamond roller, and effectively reducing the consumption of cooling water, and effectively reducing the processing cost of the machine tool.

[0033] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0034] The first implementation method:

[0035] Figure 1-5 A diamond roller with a heat dissipation structure is shown, comprising a roller ring body 1, the outer ring of the roller ring body 1 is fixedly connected with a friction ring 101, the inner ring of the roller ring body 1 is provided with a water cooling groove 102, the inside of the water cooling groove 102 is fixedly connected with an evaporation circle leaf 103, and both ends of the outside of the water cooling groove 102 are fixedly connected with outer fan leaves 104;

[0036] By retaining an appropriate amount of cooling water at the bottom of the water-cooling groove 102, a layer of cooling water quickly adheres to the surface of the evaporation ring 103 during the rotation of the roller ring body 1. Through the rapid drying and evaporation of the cooling water, efficient heat dissipation of the diamond roller is achieved and the consumption of cooling water is effectively reduced.

[0037] Figure 3-8 As shown, one end of the roller ring body 1 is rotatably connected to the heat dissipation ring 2, the bottom of the heat dissipation ring 2 is fixedly connected to the bracket plate 3, the end of the bracket plate 3 is fixedly connected to the water covering plate 4, the water covering plate 4 is movably connected to the water cooling groove 102, and both ends of the water covering plate 4 are provided with passage grooves 401 corresponding to the movement of the evaporation circle page 103, and both ends of the bottom of the water covering plate 4 are paved with wiping pads 402, and the surface of the wiping pad 402 is provided with grooves 403 corresponding to the passage groove 401, and the wiping pad 402 is made of sponge material, and the cooling water is wiped to the surface of the evaporation circle page 103 by the wiping pad 402, and the evaporation circle page 103 is prevented from carrying excess cooling water to overflow the passage groove 401, and a water sealing strip 404 is fixedly connected between the left and right ends of the two wiping pads 402, and the water sealing strip 404 corresponds to the inner wall of the water cooling groove 102, and the water sealing strip 404 is used to prevent the cooling water from overflowing from the left and right ends of the water covering plate 4;

[0038] When the diamond roller rotates, the water covering plate 4 covers the cooling water at the bottom of the water cooling groove 102, effectively reducing the overflow of the cooling water due to the rotation of the evaporation circle 103. The evaporation circle 103 rotates through the passage groove 401. At the same time, the water wiping pad 402 wipes the cooling water to the surface of the evaporation circle 103, and prevents the evaporation circle 103 from carrying excess cooling water to overflow the passage groove 401. At the same time, the water sealing strip 404 is used to correspond to the inner wall of the water cooling groove 102 to prevent the cooling water from overflowing from the left and right ends of the water covering plate 4, effectively improving the stability of the cooling water at the bottom of the water cooling groove 102, reducing the leakage of cooling water from the diamond roller, and thus reducing the influence of cooling water on the processed parts on the machine tool.

[0039] Figure 1 and Figure 3 As shown, the two ends of the top of the heat dissipation ring 2 are respectively fixedly connected with an air inlet duct 201 and an exhaust duct 202, the inner ends of the air inlet duct 201 and the exhaust duct 202 are fixedly connected with a wind bin 203, and the outer ends of the air inlet duct 201 and the exhaust duct 202 are fixedly connected with an induced draft fan 204, and the opening of the wind bin 203 faces the evaporation circle 103;

[0040] The air inlet 201 and the exhaust duct 202 drive the flow of air through the induced draft fan 204. The air input by the induced draft fan 204 to the air inlet 201 is diffused through the wind bin 203. The input cold air cools the evaporator circle 103 and the exposed inner wall of the water cooling tank 102, which is convenient for the rapid drying and evaporation of the cooling water. Then the exhaust duct 202 collects the hot air and water vapor through the wind bin 203 and discharges them out of the roller ring body 1, effectively improving the air circulation inside the roller ring body 1, thereby effectively improving the heat dissipation effect of the diamond roller.

[0041] Figure 6-8As shown, the left and right ends of the bracket plate 3 are respectively fixedly connected with a water inlet pipe 301 and a drain pipe 302, and the water inlet pipe 301 and the drain pipe 302 both penetrate the water covering plate 4, and a proper amount of cooling water is added to the water cooling tank 102 at the bottom of the water covering plate 4 through the water inlet pipe 301, and the excess cooling water is discharged by using the drain pipe 302, and the inner bottoms of the water inlet pipe 301 and the drain pipe 302 are fixedly connected with a vertical pipe 303, and the length of the vertical pipe 303 on the water inlet pipe 301 is greater than the length of the vertical pipe 303 on the drain pipe 302, and the middle part of the bottom end surface of the water covering plate 4 is fixedly connected with a water level sensor 304 and a temperature sensor 305, and the long vertical pipe 303 facilitates the new cooling water to be directly sent to the bottom of the water cooling tank 102, and the water level sensor 304 and the temperature sensor 305 are used to detect the use of cooling water, so as to facilitate accurate replacement of new cooling water;

[0042] The water inlet pipe 301 and the drain pipe 302 penetrate the water covering plate 4 to add a proper amount of cooling water to the water cooling tank 102. The vertical pipe 303 on the water inlet pipe 301 is longer than the vertical pipe 303 on the drain pipe 302, so that the newly added cooling water is directly sent to the bottom of the water cooling tank 102, while the cooling water with heat is at the top of the water cooling tank 102, which is convenient for suction by the drain pipe 302. The water level of the cooling water is detected in real time by the water level sensor 304 to control the amount of cooling water, and the water temperature of the cooling water is detected in real time by the temperature sensor 305, so that the cooling water can be replaced in time when the cooling water temperature is too high.

[0043] The second implementation method:

[0044] Compared with the first embodiment, this embodiment mainly adds a water accumulation groove 405 and an annular groove 502. The specific newly added structures are as follows, and the remaining structures are consistent with the first embodiment.

[0045] Figure 7-9 As shown, a water accumulation groove 405 is provided on the upper surface of the water covering plate 4, the top end of the water sealing strip 404 extends out of the upper surface of the water covering plate 4, the water accumulation groove 405 is parallel to the water sealing strip 404, and a reflux hole 406 is provided at the bottom of the water accumulation groove 405. The cooling water falling on the water covering plate 4 is collected by the water accumulation groove 405 and returns to the water cooling groove 102 through the reflux hole 406, effectively preventing the cooling water from leaking from the diamond roller. A seepage column 407 is fixedly inserted inside the reflux hole 406. The seepage column 407 is made of sponge material. The seepage column 407 is used to block the reflux hole 406, effectively preventing the water in the water cooling groove 102 from passing through the reflux hole 406 in the reverse direction, and the cooling water in the water accumulation groove 405 can provide the seepage column 407 to seep back into the water cooling groove 102;

[0046] When there is cooling water on the upper surface of the water covering plate 4, the water sealing strips 404 extending from the left and right ends of the water covering plate 4 are used to limit the cooling water, so that the cooling water is concentrated in the water accumulation groove 405, and drips back to the water cooling groove 102 through the reflux hole 406 in the water accumulation groove 405. The reflux hole 406 is blocked by the seepage column 407, which effectively prevents the water in the water cooling groove 102 from passing through the reflux hole 406 in the reverse direction, and the cooling water in the water accumulation groove 405 can provide the seepage column 407 to infiltrate back to the water cooling groove 102.

[0047] Figure 10-11 As shown, the roller ring body 1 is fixedly connected to an assembly flange 5 at one end away from the heat dissipation ring 2, and the inner ring tube 501 is fixedly connected to the inner side of the assembly flange 5. The inner ring tube 501 is sleeved with the heat dissipation ring 2. The assembly flange 5 and the inner ring tube 501 facilitate the installation and fixation of the diamond roller, and effectively improve the installation stability of the heat dissipation ring 2. An annular groove 502 is provided at the outer middle end of the inner ring tube 501, and the annular groove 502 corresponds to the same plane as the water cooling groove 102. The water falling on the surface of the inner ring tube 501 is concentrated in the annular groove 502, which effectively prevents To prevent the cooling water on the surface of the inner ring tube 501 from being brought out of the diamond roller, thereby effectively reducing the influence of the leaked cooling water on the processing of the workpiece, the surface of the ring groove 502 is evenly arranged with blocking ribs 503, and the outside of the blocking ribs 503 is fixedly connected with water-spinning ribs 504. The cooling water on the surface of the inner ring tube 501 is blocked by the blocking ribs 503 and then thrown off by the water-spinning ribs 504, effectively reducing the residence time of the cooling water in the ring groove 502, thereby further effectively preventing the cooling water on the surface of the inner ring tube 501 from being brought out of the diamond roller;

[0048] The assembly of the flange 5 and the inner ring tube 501 facilitates the installation and fixation of the diamond roller. At the same time, the heat dissipation ring 2 is stably mounted on the inner ring tube 501, which effectively improves the installation stability of the heat dissipation ring 2, thereby effectively improving the installation stability of the heat dissipation structure on the diamond roller. When the diamond roller rotates, the cooling water dripping onto the inner ring tube 501 is concentrated in the annular groove 502, preventing the cooling water from leaking out of the diamond roller along the inner ring tube 501. The cooling water on the annular groove 502 is blocked by the blocking rib 503, and then the water droplets are thrown out by the water-throwing rib 504. When the water droplets are thrown on the top of the water-cooling groove 102, the water droplets are integrated into the water film, and the cooling water continues to be dried and evaporated. The water droplets directly thrown on the water-cooling groove 102 flow back to the bottom of the water-cooling groove 102, effectively improving the utilization rate of the cooling water, and effectively reducing the residence time of the cooling water in the annular groove 502, thereby further effectively preventing the cooling water on the surface of the inner ring tube 501 from being taken out of the diamond roller.

[0049] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
