[0028] Please refer to Figure 1-6 , the present utility model discloses a lightweight combined grinding wheel, including a bottom plate 1, a cover plate 2 and an adapter 3. The bottom plate 1 and the cover plate 2 are coaxially attached and are detachably connected through the adapter 3. A plurality of bosses 6 are formed on the surface of the bottom plate 1 facing away from the cover plate 2. The top surface of each boss 6 is covered with abrasive grains 7. The bosses 6 are spaced apart from each other, and a chip removal groove 4 is formed between two adjacent bosses 6. The chip removal groove 4 is used for discharging the grinding chips generated by grinding. The boss 6 and the bottom plate 1 are integrally formed by stamping.
[0029] Since the bottom plate 1 and the cover plate 2 are detachably connected, when the abrasive grains 7 on the boss 6 of the bottom plate 1 are worn or fall off, resulting in a deterioration of the grinding performance of the grinding wheel, the bottom plate 1 can be replaced separately. Therefore, compared with the existing brazed diamond grinding wheel, the lightweight combined grinding wheel of the present utility model has a longer service life.
[0030] Please refer to Figure 1 、 Figure 2 , the bottom plate 1 is disc-shaped, and its middle part is recessed along its own axis in the direction opposite to the protruding direction of the boss 6. The boss 6 is formed on the bottom plate 1. When the lightweight combined grinding wheel is working, the bottom plate 1 is subjected to greater force. Therefore, the bottom plate 1 can be made of A3 or No. 45 steel.
[0031] In a preferred embodiment of the present utility model, while ensuring the mechanical strength of the bottom plate 1, in order to minimize the weight of the bottom plate 1 as much as possible, the thickness of the bottom plate 1 is between 0.8 mm and 1.5 mm, such as 0.8 mm, 1 mm, 1.15 mm, 1.2 mm, 1.4 mm, 1.5 mm.
[0032] The cover plate 2 is disc-shaped, and its middle part is recessed along its own axis in the direction opposite to the protruding direction of the boss 6, and the shape of the recessed part is the same as that of the recessed part of the bottom plate 1, so that the recessed parts of the cover plate 2 and the floor can be nested. The main function of the cover plate 2 is to install the bottom plate 1 and facilitate the installation of the whole lightweight combined grinding wheel. To reduce the overall weight of the grinding wheel, the cover plate needs to be made of lightweight and high-temperature resistant materials, such as aluminum alloy and PET material.
[0033] In a preferred embodiment of the present utility model, while ensuring the mechanical strength of the cover plate 2, in order to minimize the weight of the cover plate 2 as much as possible, the thickness of the cover plate 2 is between 3 mm and 6 mm, such as 3 mm, 4 mm, 5 mm, 6 mm.
[0034] The overall diameter of the lightweight combined grinding wheel is between 75 mm and 230 mm, such as 75 mm, 100 mm, 150 mm, 200 mm, 230 mm.
[0035] At the same time, in order to further reduce the overall weight of the lightweight combined grinding wheel, a plurality of weight-reducing holes 8 are provided on both the bottom plate 1 and the cover plate 2. The weight-reducing holes 8 penetrate through the bottom plate 1 or the cover plate 2 along the thickness direction of the bottom plate 1 or the cover plate 2. The function of the weight-reducing holes 8 is to reduce the weight of the bottom plate 1 and the cover plate 2 without affecting their mechanical strength, so as to make the lightweight combined grinding wheel lighter.
[0036] The recesses of the bottom plate 1 and the cover plate 2 are nested to form the installation part 5. The adapter 3 includes a bolt 31 and a nut 32. The bolt 31 and the nut 32 cooperate to lock the bottom plate 1 and the cover plate 2. The bolt 31 is used to connect the lightweight combined grinding wheel to other devices. The bolt 31 can be connected to other devices by using its thread outside the nut 32, or can be connected to other devices by other suitable means.
[0037] In a preferred embodiment of the present invention, a screw hole 33 is provided along the axis of the bolt 31 through the bolt 31. In this way, while the bolt 31 and the nut 32 lock the bottom plate 1 and the cover plate 2, the connection between the lightweight combined grinding wheel and other devices can be achieved by using the screw hole 33 on the bolt 31.
[0038] The abrasive grains 7 are diamond abrasive grains. The diamond abrasive grains are fixed on the top surface of the boss 6 by brazing. The parameters of the diamond abrasive grains can be adaptively selected according to the usage scenario of the lightweight combined grinding wheel. In a preferred embodiment of the present invention, the particle size of the diamond abrasive grains is 212μm - 250μm. The brazing filler metal used for brazing the diamond abrasive grains is a nickel-based brazing filler metal, and its composition contains nickel, chromium, iron, and silicon. The percentage contents of nickel, chromium, iron, and silicon are: nickel 84% - 85%, chromium 4% - 5%, iron 6.5% - 7.5%, and silicon 4% - 5%. The diamond abrasive grains are brazed in a vacuum furnace, and the brazing temperature is 1020°C, with a holding time of 20 minutes.
[0039] The boss 6 grinds an object in combination with the abrasive grains 7 laid on its top surface. Therefore, the shape and quantity of the boss 6 are crucial for the grinding performance of the lightweight combined grinding wheel. The following shows the arrangement of the boss 6 by way of four different bosses 6 and their quantities:
[0040] In an embodiment of the present invention, the top surface of the boss 6 is elliptical. A plurality of bosses 6 are evenly spaced around the axis of the bottom plate 1. Specifically, please refer to Figure 3 , the quantity of the bosses 6 can be eight, and the eight bosses 6 are evenly spaced around the axis of the bottom plate 1, and the included angles between the major axes of the two ellipses corresponding to adjacent two bosses 6 are all equal.
[0041] In an embodiment of the present invention, the top surface of the boss 6 is arrow-shaped. A plurality of bosses 6 are evenly spaced around the axis of the bottom plate 1. Specifically, please refer to Figure 4 , the quantity of the bosses 6 can be twelve. The projection of the outer edge of the boss 6 along the axis of the bottom plate 1 on the bottom plate 1 is flush with the outer edge of the bottom plate 1. The twelve bosses 6 are evenly spaced around the axis of the bottom plate 1, and the arrows of the twelve bosses 6 all point in the same direction.
[0042] In an embodiment of the present utility model, the top surface of the boss 6 is trapezoidal. A plurality of bosses 6 are evenly spaced around the axis of the base plate 1. The two bases of the trapezoid corresponding to the boss 6 are both arc-shaped, and the centers of the circles are both located on the axis of the base plate 1. Among them, the base plate 1 with a longer length is closer to the outer edge of the base plate 1. The number of bosses 6 can be six or eight. Figure 5 The situation where the number of bosses 6 is six is shown. Figure 6 The situation where the number of bosses 6 is eight is shown.
[0043] In other embodiments of the present utility model, the shape and number of the bosses 6 can be appropriately changed according to the requirements in the actual application of the lightweight combined grinding wheel.
[0044] The lightweight combined grinding wheel of the present utility model forms a plurality of bosses 6 on the base plate 1, forms chip discharge grooves 4 between two adjacent bosses 6, and deposits diamond abrasive grains on the top surface of the bosses 6 by brazing. As a result, the chips generated during grinding of the lightweight combined grinding wheel can be discharged through the chip discharge grooves 4, improving the convenience of chip accommodation and discharge of the grinding wheel, reducing the dust generated during grinding, and improving the sharpness of the grinding wheel. At the same time, due to the convenience of chip accommodation and discharge. And, since the base plate 1 and the cover plate 2 are detachably connected, when the abrasive grains 7 are worn and fall off, resulting in a deterioration of the grinding performance of the grinding wheel, the base plate 1 can be replaced separately, thereby improving the service life of the grinding wheel.
[0045] In addition, the lightweight combined grinding wheel of the present utility model reduces the overall weight of the grinding wheel and achieves lightweight by opening weight reduction holes 8 on the base plate 1 and the cover plate 2 and selecting a lightweight and high-temperature resistant material as the cover plate 2.
[0046] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not used to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
