Description

Technical Field

[0001] The utility model belongs to the technical field of cutting tools, and particularly relates to an explosion-proof resin grinding wheel. Background Art

[0002] Resin grinding wheels are made of resin and offer high strength. They are used in cutting wheels, double-end grinding wheels, heavy-duty grinding wheels, and polishing wheels. They offer a certain degree of elasticity, low heat resistance, good self-sharpening properties, ease of manufacture, and a short production cycle. They are widely used for rough grinding, rough grinding, parting off, and free grinding, such as grinding steel ingots and deburring castings.

[0003] At present, the grinding surface of the grinding wheel we commonly use is a whole surface. When the grinding wheel rotates at high speed to grind the workpiece, high temperature will be generated in the contact area between the grinding wheel and the workpiece. This high temperature will reduce the hardness of the grinding wheel, thereby affecting the life of the grinding wheel itself and the parts are prone to thermal deformation due to excessive temperature. However, the heat dissipation effect of the existing grinding wheel is poor, which can easily accelerate the aging speed of the grinding wheel and reduce the service life. For this reason, we propose an anti-cracking resin grinding wheel. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the present invention is to provide an anti-cracking resin grinding wheel.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0006] An anti-explosion resin grinding wheel comprises an upper fixed base, a grinding wheel body and a lower fixed base arranged in sequence from top to bottom, the grinding wheel body being sandwiched between the upper fixed base and the lower fixed base, a plurality of bolts being connected between the upper fixed base, the grinding wheel body and the lower fixed base, and the upper fixed base and the lower fixed base being provided with a plurality of groups of air holes of different apertures;

[0007] The upper fixed base and the lower fixed base are both provided with matching gaskets, and the gaskets are radially connected with a plurality of heat sinks based on the center of the circle.

[0008] It is further defined that one side of the upper fixed base is connected to a threaded barrel, and one side of the lower fixed base is connected to an adaptive internal threaded insert barrel, and the upper fixed base is threadedly connected to the internal threaded insert barrel of the lower fixed base through the threaded barrel. Such a structural design can facilitate and quickly install and disassemble the upper fixed base and the lower fixed base, and has the effect of pre-installation and reinforcement of stable connection.

[0009] It is further defined that the apertures of each group of air holes dispersed outward from the center of the circle in the upper fixed base and the lower fixed base gradually become larger. Such a structural design allows for the stable installation of the grinding wheel body and more efficient heat dissipation of the outer side of the grinding wheel body close to the heat generated by the workpiece being processed.

[0010] It is further defined that the bolt is an external hexagonal bolt, the other end of the bolt is threadedly connected to a external hexagonal nut, and the upper fixed base and the lower fixed base are both provided with matching embedding grooves. Such a structural design can save installation space and facilitate the staff to install and remove the bolts.

[0011] It is further defined that the outer walls of the upper and lower fixed base shafts are connected with heat dissipation rings. Such a structural design can enhance the heat dissipation efficiency at the position where the upper and lower fixed bases contact the grinding wheel body.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model mainly includes three independent components: an upper fixed base, a grinding wheel body, and a lower fixed base. The upper fixed base and the lower fixed base are assembled, and the grinding wheel body is clamped between the upper fixed base and the lower fixed base, and then fixed by multiple bolts, which improves the installation stability of the grinding wheel body, facilitates subsequent installation and disassembly, and replaces different grinding wheel bodies, saving replacement costs;

[0014] 2. In addition, multiple gaskets arranged on the upper and lower fixed bases can exchange heat and cool the heated grinding wheel body. Multiple sets of air holes can facilitate ventilation, heat exchange and cooling of the heat sink, thereby improving the heat dissipation efficiency of the grinding wheel body, preventing the grinding wheel body from accelerating aging and cracking due to heat, and extending its service life.

[0015] 3. The upper fixed base and the lower fixed base can also play a certain anti-deformation effect on the grinding wheel body to prevent affecting the subsequent work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0028] Example 1, as Figure 1 、 Figure 2 and Figure 3 As shown, an explosion-proof resin grinding wheel, the grinding wheel body 2 is sandwiched between the upper fixed base 1 and the lower fixed base 3, a plurality of bolts 4 are connected between the upper fixed base 1, the grinding wheel body 2 and the lower fixed base 3, and the upper fixed base 1 and the lower fixed base 3 are both provided with a plurality of groups of air holes 301 of different apertures;

[0029] The upper fixed base 1 and the lower fixed base 3 are both provided with matching gaskets 5 , and the gaskets 5 are radially connected with a plurality of heat sinks 501 based on the center of the circle.

[0030] In this embodiment, the upper fixed base 1, the grinding wheel body 2 and the lower fixed base 3 are three separate components. The staff first needs to install the circular hole of the grinding wheel body 2 to the outside of the circular hole of the lower fixed base 3, and assemble the upper fixed base 1 to the lower fixed base 3, so that the upper fixed base 1, the grinding wheel body 2 and the lower fixed base 3 are closely spliced ​​and arranged, wherein the two gaskets 5 are located on both sides of the grinding wheel body 2, and then the upper fixed base 1, the grinding wheel body 2 and the lower fixed base 3 are connected and fixed by multiple bolts 4. This installation method is simple and easy to disassemble, which is convenient for subsequent replacement of the grinding wheel body 2 separately, saving the cost of overall replacement;

[0031] In addition, the multiple heat sinks 501 connected to the gasket 5 have the effect of heat exchange and cooling the heated grinding wheel body 2, and the multiple groups of air holes 301 set on the upper fixed base 1 and the lower fixed base 3 have the effect of ventilating, exchanging heat and cooling the heat sink 501, thereby improving the heat dissipation effect of the grinding wheel body 2, preventing the grinding wheel body 2 from accelerating aging and bursting, and extending its service life. The upper fixed base 1 and the lower fixed base 3 can also have a certain anti-deformation effect on the grinding wheel body 2 to prevent it from affecting subsequent work efficiency.

[0032] Example 2, as Figure 2 and Figure 3 As shown, this embodiment adds the following structure on the basis of embodiment 1: a threaded barrel 101 is connected to one side of the upper fixed base 1, and a matching internal threaded insert 302 is connected to one side of the lower fixed base 3. The upper fixed base 1 is threadedly connected to the internal threaded insert 302 of the lower fixed base 3 through the threaded barrel 101.

[0033] In this embodiment, the circular hole of the grinding wheel body 2 is sleeved onto the outer wall of the internal threaded insert 302, and then the threaded tube 101 of the upper fixed base 1 is threadedly connected to the inside of the internal threaded insert 302 of the lower fixed base 3, which has a quick pre-installation effect, thereby preventing the subsequent loosening of the bolt 4 and the direct falling off of the grinding wheel body 2.

[0034] Example 3, as Figure 2 and Figure 3 As shown, this embodiment adds the following structure on the basis of embodiment 1: the apertures of the groups of air holes 301 dispersed outward from the center of the circle in the upper fixed base 1 and the lower fixed base 3 gradually increase.

[0035] In this embodiment, the main heat generation position of the grinding wheel body 2 is at the edge of the outer wall of the shaft body, and the apertures of each group of air holes 301 dispersed outward from the center of the circle in the upper fixed base 1 and the lower fixed base 3 gradually become larger, which can increase the area of ​​the outer position of the same heat sink 501 in contact with the air, thereby improving the heat dissipation efficiency of the outer position of the heat sink 501.

[0036] Example 4, as Figure 2 and Figure 3 As shown, this embodiment adds the following structure on the basis of embodiment 1: the bolt 4 is an external hexagonal bolt, the other end of the bolt 4 is threadedly connected to an external hexagonal nut 401, and the upper fixed base 1 and the lower fixed base 3 are both provided with matching embedding grooves.

[0037] In this embodiment, after the upper fixed base 1, the grinding wheel body 2 and the lower fixed base 3 are assembled, each bolt 4 is threadedly connected to each corresponding mounting hole, and then the external hexagonal nut 401 is manually connected to the other end of the bolt 4, thereby reinforcing the bolt 4.

[0038] Example 5, as Figure 2 and Figure 3 As shown, this embodiment adds the following structure on the basis of embodiment 1: the outer walls of the upper fixed base 1 and the lower fixed base 3 are connected with heat dissipation rings 6.

[0039] In this embodiment, two heat dissipation rings 6 are respectively connected to both sides of the grinding wheel body 2 to improve the heat conduction and heat dissipation efficiency.
