Description

Technical Field

[0001] This invention relates to the field of grinding wheel technology, and specifically to an active heat dissipation grinding wheel. Background Technology

[0002] In industrial production, grinding wheels are often used to grind workpiece materials. When grinding workpieces and other materials, a lot of grinding heat is often generated due to friction. If this heat cannot be dissipated in time, it can easily cause problems such as burns and cracks on the workpiece surface, which seriously affects the surface processing quality of the workpiece.

[0003] In existing technologies, most methods improve heat dissipation efficiency by increasing the heat dissipation area or changing the grinding wheel configuration. However, the actual heat dissipation effect is not ideal, and it is easy to cause grinding debris to fill the material during the grinding process and cause poor chip removal. This not only scratches the surface of the workpiece, but also seriously affects the service life of the grinding wheel.

[0004] Therefore, it is necessary to design a grinding wheel that can actively dissipate heat during use to solve the above-mentioned technical problems. Summary of the Invention

Detailed Implementation

[0017] The technical solution of the present invention will be further described in detail below through specific embodiments. Example

[0018] like Figure 1-5As shown, this invention provides an active heat dissipation grinding wheel, including a grinding wheel body. The grinding wheel body includes a base 1, with a through hole in the center of the base 1 and an annular grinding layer 2 around the periphery of the base 1. A flat cylindrical shell 3 is provided inside the through hole. Multiple positioning cylinders 12 are fixedly arranged circumferentially inside the base 1 along the shell 3. A counterweight 11 is slidably arranged inside the positioning cylinder 12. An annular limiting plate 17 for the counterweight 11 is provided inside the positioning cylinder 12. A chip removal channel 5 is provided inside the base 1 corresponding to each positioning cylinder 12. The chip removal channel 5 penetrates the grinding layer 2. A slider 7 is slidably arranged inside the chip removal channel 5. The slider 7 is provided with a guide hole for chip removal. A guide rod 6 is fixed inside the channel 5 for the guide hole. A thrust spring 8 is provided inside the chip removal channel 5 to apply elastic thrust to the slider 7. The chip removal channel 5 is connected to the through hole through the connecting channel 9. A chip removal hole 5-1 extending to the chip removal channel 5 is provided on the side of the base 1. A through hole 1 corresponding to the connecting channel 9 and a through hole 2 corresponding to the positioning cylinder 12 are provided on the housing 3. One end of the slider 7 is connected to the pull rope. The other end of the pull rope passes through the through hole 1, goes around the reversing wheel 4 rotatably set in the housing 3, and then passes through the through hole 2 to enter the positioning cylinder 12 and connects with the counterweight 11. Multiple oiling components 13 are provided around the periphery of the grinding wheel body in the circumferential direction.

[0019] To improve the cooling rate of the grinding area and prevent workpiece burns, the aforementioned oiling assembly 13 includes a housing 13-1 fixed within the base 1. A steel ball 13-4 is disposed within the housing 13-1. One end of the housing 13-1 has a through hole for part of the steel ball 13-4 to pass through. A pressure plate 13-2 for the steel ball 13-4 is also disposed within the housing 13-1. An elastic push rod 13-3 is disposed within the housing 13-1. The telescopic end of the elastic push rod 13-3 is connected to the pressure plate 13-2. A support tube 13-12 is disposed through the pressure plate 13-2. One end of the support tube 13-12 has an oil brush 13-13. The oil brush 13-13 includes a base plate and a sponge fixed on the base plate. The sponge portion is in contact with the steel ball 13-4. The end of the support tube 13-12... The outer shell 13-1 extends into the sponge. The outer shell 13-1 also has an outer shell 13-5. The outer shell 13-5 contains a partition 13-6, forming an oil cavity 13-7 between the partition 13-6 and the outer shell 13-5. The partition 13-6 also has an oil outlet 13-9. An n-shaped rod 13-8 slides through the pressure plate 13-2, with both ends connected to the pressure plate 13-2. The oil outlet 13-9 is connected to the support tube 13-12 via a connecting hose 13-11. The n-shaped rod 13-8 also has a conical head 13-10 for the oil outlet 13-9. The outer shell 13-5 also has an oil inlet 13-14 extending out of the base 1, with a sealing plug at the oil inlet 13-14. The grinding layer 2 has a notch for the steel ball.

[0020] To further improve the cooling rate of the grinding area, the above-mentioned through hole corresponds to the rear side of the housing 3 as an air inlet chamber 1-1. The housing 3 is provided with a support rod 14 coaxial with the housing 3 in the air inlet chamber 1-1, and the support rod 14 is provided with multiple fan blades 15. The side wall of the air inlet chamber 1-1 is provided with multiple exhaust ducts 1-2 that penetrate the substrate 1 and the grinding layer 2.

[0021] To facilitate the driving and installation of the grinding wheel, the aforementioned through hole corresponds to a positioning hole 1-3 on the front side of the housing 3 for the drive rod. The base 1 has multiple positioning grooves 1-4 extending radially outward from the positioning holes 1-3, and each positioning groove 1-4 has multiple threaded cylinders 1-6. During actual installation and use, the end of the drive rod is inserted into the positioning hole 1-3. A positioning plate corresponding to the positioning groove 1-4 is fixed to the drive rod. The positioning plate has mounting holes corresponding to the threaded cylinders 1-6. The positioning plate is fixedly installed to the grinding wheel using fastening bolts corresponding to the threaded cylinders 1-6.

[0022] It should be noted that when the grinding wheel is in use, its rotation relies on centrifugal force to make the counterweight 11 and the end of the positioning cylinder 12 away from the housing 3 fit together. When the counterweight 11 and the end of the positioning cylinder 12 away from the housing 3 fit together, the slider 7 does not block the chip removal hole 5-1.

[0023] To facilitate cleaning of the chip removal channel 5, metal bristles are provided on the slider 7 for the chip removal channel 5.

[0024] To improve the performance of the grinding layer 2, diamond particles are evenly distributed in the grinding layer 2 itself.

[0025] To further improve the structural strength of the grinding wheel, a fiberglass mesh 16 is provided inside the aforementioned substrate 1.

[0026] To improve chip removal speed during workpiece grinding, multiple chip removal grooves 1-7 are provided on both sides of the grinding wheel body.

[0027] To facilitate the positioning of the counterweight 11, the positioning cylinder 12 is provided with an annular limiting plate 17 for the counterweight 11.

[0028] To ensure that the counterweight 11 can slide smoothly inside the positioning cylinder 12, a through air hole is provided on the counterweight 11.

[0029] Considering that the grinding wheel reaches high temperatures during operation, the pull rope is made of metal fiber to ensure its structural strength.

[0030] The specific working principle of this invention is as follows: When the grinding wheel is in use, it rotates at high speed, and the counterweight 11 pulls the slider 7 to move, thereby opening the chip removal hole 5-1. When grinding the workpiece, the hot airflow carries some chips out from the chip removal channel 5 and the chip removal hole 5-1, and some chips are discharged from the chip removal groove 1-7.

[0031] In addition, when grinding the workpiece, the steel ball 13-4 in the oiling assembly 13 comes into contact with the material being ground. At this time, the steel ball 13-4 pushes the pressure plate 13-2 to move, and then the pressure plate 13-2 pushes the n-shaped rod 13-8 to move. Then the conical head 13-10 opens the oil outlet 13-9. Next, the cooling oil in the oil chamber 13-7 is discharged through the oil outlet 13-9, and then enters the sponge of the oil brush 13-13 through the connecting hose 13-11 to be applied to the surface of the steel ball 13-4. The steel ball 13-4 then applies the oil to the grinding area, thereby accelerating the cooling speed of the grinding area.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
