Description

Technical Field

[0001] This utility model relates to the field of grinding tool technology, and in particular to a grinding wheel substrate. Background Technology

[0002] Abrasive wheels play an important role in industrial production and are widely used in industrial processing. They are mainly used for grinding and polishing. From large-scale production of automobiles, ships, and aviation equipment to small-scale production of jade, shoe heels, and stainless steel products, a large number of abrasive wheels are needed. Abrasive wheels belong to the category of industrial consumables and are also necessities in industrial production.

[0003] Abrasive wheels typically consist of a set of abrasive sheets stacked in an orderly manner on a base. The base is mostly made of plastic or mesh fiberglass. There are mounting holes in the middle of the base. The abrasive wheel is fixed to the connecting shaft of a special tool or angle grinder through the mounting holes for mechanical or manual grinding. The rotation of the connecting shaft of the angle grinder drives the abrasive wheel to rotate at high speed to grind and polish the workpiece.

[0004] When installing the abrasive wheel on the angle grinder, the inner side of the perforated ring on the base is fitted against the outer side of the limiting boss on the angle grinder's pressure plate. Then, the nut plate is threadedly connected to the angle grinder's connecting shaft, pressing the abrasive wheel between the nut plate and the pressure plate to limit and secure it. However, the nut plate, being a separate small part, is easily lost when installing or removing the abrasive wheel from the angle grinder, and replacing it with a compatible nut plate is quite troublesome. Summary of the Invention

[0005] To address the problem that existing grinding tools cannot disassemble or assemble grinding wheels if the small mounting and disassembly nut plate is lost, this utility model proposes a grinding wheel base. The mounting component is fixed in the mounting hole of the base by a fixing plate fixedly sleeved on the mounting cylinder. The internal thread on the inner side of the mounting cylinder enables quick disassembly and detachment of the grinding wheel from the grinding tool, improving the disassembly and assembly speed and preventing loss.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A grinding wheel base includes a mounting hole located in the center of the base. A mounting component is inserted through the mounting hole. The mounting component includes a mounting cylinder, and a fixing plate is fixedly sleeved on the outer side of the mounting cylinder. The area of ​​the fixing plate is larger than the area of ​​the mounting hole. One side of the fixing plate contacts the base and is fixedly connected to the base. The other end of the mounting cylinder extends out of the mounting hole, and the inner side of the mounting cylinder is provided with an internal thread. The internal thread on the inner side of the mounting cylinder engages with the external thread on the connecting shaft of the angle grinder to achieve quick assembly and disassembly of the grinding wheel base from the angle grinder.

[0008] Preferably, the mounting component further includes a first limiting plate and a second limiting plate. The first limiting plate is fixed to one end of the mounting cylinder and has an opening that mates with the mounting cylinder. The second limiting plate is fixed to the outside of the mounting cylinder. One side of the fixing plate contacts the first limiting plate, and the other side contacts the second limiting plate. The first and second limiting plates sandwich the fixing plate in the middle, and the fixing plate is then fixedly connected to the base to achieve the fixation of the mounting component to the base.

[0009] Preferably, the cross-section of the outer side of the mounting cylinder is a regular polygon. This prevents the mounting cylinder from rotating relative to the fixing plate during the grinding process, which could cause the grinding wheel base to detach from the angle grinder and create a safety hazard.

[0010] Preferably, the second limiting plate is located within the mounting hole. This prevents positional interference between the grinding wheel and the part to be ground during the grinding process.

[0011] Preferably, the fixing plate and the mounting cylinder are integrally formed.

[0012] Preferably, multiple toothed plates are evenly fixed to the outer circumferential surface of the fixing plate, and the toothed plates are inserted into the substrate at an angle. After the toothed plates are inserted into the substrate, they are not completely fixed to the substrate. At this time, they need to be baked at high temperature to make the substrate and the toothed plates bond together.

[0013] Preferably, the end face of the mounting cylinder is flush with the end face of the fixing plate.

[0014] The beneficial effects of this utility model through the above technical solution are as follows: In this utility model, an installation component is inserted into the installation hole in the middle of the base, and a fixing plate is fixed to the end of the installation component. The fixing plate has an opening that cooperates with the installation cylinder in the installation component, which allows the connecting shaft of the grinding tool to be inserted and threadedly connected to the installation cylinder, realizing the quick disassembly and reassembly of the grinding wheel on the grinding tool. Compared with the original installation method of clamping the grinding wheel between the pressure plate and the nut plate by the nut plate, the grinding wheel in this utility model is more stably fixed on the grinding tool, and at the same time, there is no problem that the grinding tool cannot be disassembled and reassembled after the nut plate is lost.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] like Figures 1 to 7 As shown, this embodiment provides a grinding wheel base, including a mounting hole 11 located in the middle of the base 1. A mounting component 2 is inserted through the mounting hole 11. The mounting component 2 includes a mounting cylinder 21. A fixing plate 3 is fixedly sleeved on the outer side of the mounting cylinder 21. The cross-section of the outer side of the mounting cylinder 21 is a regular hexagon. The cross-section of the inner side of the fixing plate 3 is also a regular hexagon, so as to avoid relative rotation between the mounting cylinder 21 and the fixing plate 3.

[0027] In this embodiment, the fixing plate 3 is fixedly sleeved on the mounting cylinder 21. Specifically, the mounting component 2 further includes a first limiting plate 22 and a second limiting plate 23. The first limiting plate 22 is fixed to one end of the mounting cylinder 21 and has an opening that mates with the mounting cylinder 21. The second limiting plate 23 is fixed to the outside of the mounting cylinder 21. One side of the fixing plate 3 contacts the first limiting plate 22, and the other side contacts the second limiting plate 23. The second limiting plate 23 is located inside the mounting hole 11. The other end of the mounting cylinder 21 extends out of the mounting hole 11, and the inner side of the mounting cylinder 21 has an internal thread 211. The first limiting plate 22 and the second limiting plate 23 clamp the fixing plate 3 in the middle, thereby connecting and fixing the mounting component 2 and the fixing plate 3.

[0028] refer to Figure 7 The specific installation method is as follows: First, insert the mounting cylinder 21, with the first limiting plate 22 fixed at its end, into the fixing plate 3. Then, thread the screw on the threading gun through the opening on the first limiting plate 22 and thread it onto the mounting cylinder 21. Then, fix the fixing plate 3 in place. The screw on the threading gun rotates, causing the mounting cylinder 21 to move inward on the screw on the threading gun. After moving to its limit, the thinner deformable part on the mounting cylinder 21 deforms into... Figure 7 The shape of the second limiting plate 23 in the middle clamps the fixing plate 3. This is a riveting process, which is existing technology.

[0029] Furthermore, the fixing plate 3 is located at the end of the mounting cylinder 21 and the end face of the mounting cylinder 21 is flush with the end face of the fixing plate 3. The area of ​​the fixing plate 3 is larger than the area of ​​the mounting hole 11. One side of the fixing plate 3 contacts the base 1 and is fixedly connected to the base 1.

[0030] Specifically, six toothed plates 31 are evenly fixed to the outer circumference of the fixing plate 3, and the toothed plates 31 are inserted into the base 1 at an angle. After the toothed plates 31 are bent and inserted into the base 1 at an angle, they are not yet completely fixed to the base 1. Then, through high temperature baking, the base 1 made of glass fiber will be bonded to the toothed plates 31, realizing the fixed connection between the fixing plate 3 and the base 1.

[0031] In another embodiment, the fixing plate 3 and the mounting cylinder 21 are integrally formed. In this case, the fixing plate 3 and the mounting cylinder 21 are a whole, and it is only necessary to fix the fixing plate 3 to the base 1 (the specific fixing method is the same as the above embodiment). In this embodiment, after the circular cylinder is drawn out by stamping on the iron plate, the internal thread is processed in the cylinder by tapping process to achieve the subsequent fixed connection with the angle grinder.

[0032] refer to Figures 8-9The base 1 is provided with a first mounting ring surface 12, an annular fixing surface 13 and a second mounting ring surface 14 from the inside to the outside. The first mounting ring surface 12 has a mounting hole 11 in the middle. The annular fixing surface 13 is an arc surface with a lower inner side and a higher outer side. Multiple abrasive blades 4 are inclinedly arranged on the second mounting ring surface 14. The multiple abrasive blades 4 are evenly fixed on the second mounting ring surface 14 to form an abrasive wheel. The abrasive blades 4 are glued to the base 1 by adhesive. The base 1 can be made of fiberglass mesh, metal or plastic.
