Description

Technical Field

[0001] This invention relates to the field of diamond grinding wheel technology, specifically an electroplated composite diamond grinding wheel. Background Art

[0002] As is well known, diamond grinding wheels are a type of diamond tool, mainly used for surface grinding of various refractory materials. A diamond grinding wheel consists of a base and a cutting head, allowing the electroplated diamond grinding wheel to maintain high precision and stability during use. This improves the accuracy of the grinding process. The diamond grinding wheel is mounted on the output shaft of an angle grinder or polishing machine, which drives the diamond grinding wheel to rotate via the output shaft, enabling the diamond grinding wheel to perform grinding processing on the material.

[0003] The production steps of the electroplated combined diamond grinding wheel are as follows: (1) Making the electroplated diamond plate: Place the metal plate substrate in the electroplating solution, and deposit the metal on the surface of the metal plate substrate through the electroplating principle, so that the metal deposition covers the diamond and forms the electroplated diamond plate; (2) Cutting treatment of the cutting head: According to the shape of the grinding wheel substrate, the electroplated diamond plate is cut into the outer circle of the grinding wheel substrate by cutting equipment to make the cutting head of the electroplated diamond grinding wheel; (3) Welding treatment: The grinding wheel cutting head is placed on the welding surface of the grinding wheel substrate by welding equipment and welded. After the welding is completed, the complete electroplated combined diamond grinding wheel is obtained.

[0004] For example, the patent entitled "A Combined Diamond Grinding Wheel" published on July 1, 2022, with announcement number CN216859420U, discloses a combined diamond grinding wheel, including a mounting disc, a connecting cylinder connected to one side of the mounting disc, a wheel disc connected to one end of the connecting cylinder, a first cutting head connected to one side of the wheel disc, side plates connected to all four sides of the connecting cylinder, a second cutting head connected to the outer side of the side plates, a lead screw inside the connecting cylinder, bearings fitted at both ends of the lead screw, bearing seats fitted to the outer side of the bearings, one side of the bearing seats connected to the inner side of the connecting cylinder, several sliders fitted to the outer side of the lead screw, first connecting blocks installed on all four sides of the sliders, a second connecting block connected to one side of the first connecting block, one end of the second connecting block penetrating the inner side of the connecting cylinder, the second connecting block and the connecting cylinder being slidably connected, and one end of the second connecting block being connected to the inner side of the side plates. This type of combined diamond grinding wheel has a simple and reasonable structure, novel design, and is easy and convenient to operate. It can effectively achieve multi-functional grinding, and the grinding depth can be adjusted, making it highly practical.

[0005] The shortcoming of the existing technology is that after the diamond grinding wheel is installed on the output shaft, the output shaft drives the diamond grinding wheel to rotate in order to achieve grinding of the material. When the diamond grinding wheel grinds the material, the cutting edge of the diamond grinding wheel must be pressed tightly against the material to grind the material. However, when the edge of the diamond grinding wheel is pressed tightly against the material, the edge of the diamond grinding wheel is easily broken or bent due to excessive force, which will damage the diamond grinding wheel and affect the grinding efficiency and quality of the material. Summary of the Invention

[0006] The purpose of this invention is to provide an electroplated combined diamond grinding wheel to solve the technical problems in related technologies.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an electroplated combined diamond grinding wheel, comprising an output shaft and a grinding wheel body, wherein the grinding wheel body is mounted on the output shaft, and a plurality of cutter heads are disposed on the end face of the grinding wheel body, the cutter head body comprising a metal plate body and a diamond sheet body, two diamond sheet bodies being connected to both sides of the same metal plate body, the thickness of the cutter head body being adjustable, and further comprising an auxiliary unit, wherein the auxiliary unit comprises an auxiliary shaft, the auxiliary shaft being fixedly mounted on the output shaft, and a plurality of elastic telescopic compression rods being uniformly disposed along the circumferential direction on the auxiliary shaft, the auxiliary shaft and the plurality of elastic telescopic compression rods abutting against the end face of the grinding wheel body opposite to the cutter head body.

[0008] As described above, the elastic telescopic extrusion rod includes auxiliary rods. Multiple auxiliary rods are evenly arranged along the circumferential direction on the auxiliary shaft. Each auxiliary rod has a positioning rod at its end. Each positioning rod has a sliding groove. A pressing rod is slidably installed in each sliding groove. Each pressing rod and its corresponding inner wall of the sliding groove are connected by a first elastic element. The first elastic element provides elastic force to the pressing rod, so that the pressing rod and the edge of the grinding wheel body abut against each other.

[0009] The auxiliary unit further includes a straight plate. Multiple straight grooves are evenly opened on the outer wall of the auxiliary shaft along its circumferential direction. A straight plate is slidably installed in each of the straight grooves. A square groove is opened on each of the auxiliary rods. A straight plate is slidably installed in each of the square grooves. Each straight plate and the inner wall of the square groove are connected by a driving component.

[0010] As described above, the auxiliary shaft is provided with a plurality of slots evenly distributed along its circumferential direction. Each slot is connected to its corresponding straight groove. A driven plate is slidably installed in each slot. Each driven plate and the inner wall of its corresponding slot are connected by a second elastic member.

[0011] As described above, each of the driven plates is uniformly provided with a plurality of first teeth, and each of the straight plates is uniformly provided with a plurality of second teeth.

[0012] As described above, each of the straight slots is equipped with a transmission gear via a positioning shaft. Each of the transmission gears meshes with the first tooth on its corresponding driven plate and with the second tooth on its corresponding straight plate.

[0013] As described above, the grinding wheel body is divided into a grinding wheel disc and a cutter head body. The grinding wheel disc is mounted on the output shaft and abuts against the end of the auxiliary shaft. Multiple mounting grooves are evenly opened along the circumferential direction on the outer wall edge of the grinding wheel disc, and a cutter head body is welded into each mounting groove.

[0014] As mentioned above, the end of the output shaft is threaded, and the grinding wheel disc is mounted on the output shaft by a nut and a washer.

[0015] As described above, a wedge plate is provided on each of the two sides of each straight groove on the auxiliary shaft, and a wedge surface is provided on the side wall of the square groove of each auxiliary rod. The two wedge plates on the same straight groove side and the two wedge surfaces on the corresponding auxiliary rod are wedge-shaped to each other.

[0016] The aforementioned straight plates and the inner walls of the square grooves are each connected by a third elastic element.

[0017] The beneficial effects of this invention are as follows: When the grinding wheel body grinds the material, the grinding wheel body is mounted on the output shaft. Since the elastic telescopic extrusion rod is pressed against the outer wall of the grinding wheel body, the elastic telescopic extrusion rod performs a pressing operation on the outer edge of the grinding wheel body. When the output shaft drives the grinding wheel body to grind the material, the edge of the grinding wheel body grinds the material, making the grinding wheel body more uniformly stressed and preventing damage caused by uneven stress on the grinding wheel body, thereby improving the efficiency of material grinding.

[0036] In order to make those skilled in the art better understand the technical solution of the present invention, Figure 1 To the attached Figure 15 The present invention is further described in detail.

[0037] One embodiment of the present invention relates to an electroplated combined diamond grinding wheel, comprising an output shaft 1 and a grinding wheel body 2. The grinding wheel body 2 is mounted on the output shaft 1. Multiple cutter heads 10 are disposed on the end face of the grinding wheel body. Each cutter head 10 comprises a metal plate body 101 and a diamond sheet body 102. Two diamond sheet bodies 102 are connected to both sides of the same metal plate body 101. The thickness of the cutter head body 10 is adjustable. The invention also includes an auxiliary unit, comprising an auxiliary shaft 3. The auxiliary shaft 3 is fixedly mounted on the output shaft 1. Multiple elastic telescopic compression rods are uniformly disposed on the auxiliary shaft 3 along its circumferential direction. The auxiliary shaft 3 and the multiple elastic telescopic compression rods abut against the end face of the grinding wheel body 2 opposite to the cutter head body 10.

[0038] Specifically, a diamond grinding wheel is a device used for grinding materials. The electroplated composite diamond grinding wheel (i.e., the grinding wheel body 2) is produced through electroplating. The grinding wheel body 2 consists of a grinding disc 9 and a cutter head body 10. The grinding disc 9 is fixedly connected to the output shaft 1 and abuts against the end of the auxiliary shaft 3. Multiple mounting slots are evenly distributed along the circumferential direction on the outer edge of the grinding disc 9. Each mounting slot contains a welded cutter head body 10. The cutter head body 10 includes a metal plate body 101 and diamond sheet bodies 102. Two diamond sheet bodies 102 are connected to both sides of the same metal plate body 101. The two outer surfaces of the cutter head body 10 are diamond sheet bodies 102. The two diamond sheet bodies 102 are connected to the metal plate body 101 by brazing, gluing, or mechanical means (e.g.,...). Figure 1As shown), heat dissipation grooves 103 are provided on both sides of the metal plate body 101 and at the connection part of the two diamond sheet bodies 102 (as shown). Figure 3 As shown), when the cutter head body 10 grinds the material, friction occurs between the cutter head body 10 and the material, causing the temperature of the cutter head body 10 to rise. The heat dissipation groove 103 dissipates the heat generated by friction between the cutter head body 10 and the material, reducing the operating temperature of the cutter head body 10. The connecting surfaces of the two diamond sheet bodies 102 and the metal plate body 101 are welded into the mounting groove. The thickness of the cutter head body 10 is adjustable; that is, when the thickness of the cutter head body 10 needs to be adjusted, the two cutter head bodies 10 are connected in the middle through a metal plate body 101, thereby realizing the thickness adjustment of the cutter head body 10 (e.g., Figure 2As shown), when the grinding wheel body 2 grinds the material, it does so by the cutter head body 10 pressing against the material. The cutter head body 10 can be a block with an arc-shaped structure, where each arc-shaped structure is an arc-shaped structure in the same rotation direction (i.e., in the rotation direction of the output shaft 1). The cutter head body 10 can also be a block-shaped structure. Both types of structures enable the cutter head body 10 to grind the material. The output shaft 1 is a rotatable shaft. The output shaft 1 can be welded to the output end of the power component (the power component is a device that can rotate, preferably a motor), or it can be directly used as the output shaft 1 of the power component. The end of the output shaft 1 is... The threaded grinding wheel disc 9 is mounted on the output shaft 1 via a nut 14 and a washer. The auxiliary unit includes an auxiliary shaft 3, which is fixedly mounted on the output shaft 1, forming a section with a larger radial dimension on the output shaft 1. The elastic telescopic compression rod includes auxiliary rods 4. Multiple auxiliary rods 4 are evenly arranged along the circumferential direction on the auxiliary shaft 3. Each auxiliary rod 4 has a positioning rod 5 at its end. Each positioning rod 5 has a groove 6, and a pressing rod 7 is slidably installed in each groove 6. Each pressing rod 7 and the inner wall of its corresponding groove 6 are connected by a first elastic element 8. The auxiliary unit also includes a straight plate 11, which is mounted on the outer wall of the auxiliary shaft 3 along the... The grinding wheel has multiple straight grooves 12 evenly spaced in its circumferential direction. A straight plate 11 is slidably installed in each straight groove 12. A square groove 13 is opened on each auxiliary rod 4. A straight plate 11 is slidably installed in each square groove 13. Each straight plate 11 and the inner wall of the square groove 13 are connected by a driving component (not shown in the figure). When the grinding wheel is assembled, the positioning rod 5 and the clamping rod 7 abut against the edge of the grinding wheel disc 9 (the side away from the cutter head body 10). The grinding wheel disc 9 is fixedly installed on the output shaft 1 by the nut 14 and the washer, so that the grinding wheel disc 9 abuts against the auxiliary shaft 3. Since the clamping rod 7 and the sliding groove 6 are connected by the first elastic element 8 (the first elastic element 8 is capable of...) The first elastic element 8 provides a certain elastic force to the clamping rod 7, so that the positioning rod 5 is pressed against the outer wall of the grinding wheel disc 9 (that is, the positioning rod 5 is pressed against the back of the cutter body 10 on the grinding wheel disc 9). This allows the clamping rod 7 to provide a certain support force to the grinding wheel body 2. When the grinding wheel body 2 grinds the material, the output shaft 1 drives the cutter body 10 on the grinding wheel body 2 to grind the material. Under the clamping action of the clamping rod 7, the grinding wheel body 2 is subjected to more uniform force when grinding the material, preventing damage caused by uneven force on the grinding wheel body 2, thereby improving the efficiency of material grinding.

[0039] The shortcoming of the existing technology is that after the diamond grinding wheel is installed on the output shaft 1, the output shaft 1 drives the diamond grinding wheel to rotate to achieve grinding of the material. When the diamond grinding wheel grinds the material, the cutting edge of the diamond grinding wheel must be pressed against the material to grind it. However, when the edge of the diamond grinding wheel is pressed against the material, the edge of the diamond grinding wheel is easily broken or bent due to excessive force, which will damage the diamond grinding wheel and affect the grinding efficiency and quality of the material.

[0040] The beneficial effects of this embodiment are as follows: When the grinding wheel body 2 grinds the material, the grinding wheel body 2 is installed on the output shaft 1. Since the elastic telescopic extrusion rod is pressed against the outer wall of the grinding wheel body 2, the elastic telescopic extrusion rod performs the pressing operation on the outer edge of the grinding wheel body 2. When the output shaft 1 drives the grinding wheel body 2 to grind the material, the edge of the grinding wheel body 2 grinds the material, making the grinding wheel body 2 more uniformly stressed, preventing damage caused by uneven stress on the grinding wheel body 2, and thus improving the efficiency of material grinding.

[0041] In another embodiment of the present invention, a plurality of slots 15 are uniformly formed along the circumferential direction on the auxiliary shaft 3. Each slot 15 is interconnected with its corresponding straight groove 12. A driven plate 16 is slidably installed in each slot 15. Each driven plate 16 and the inner wall of its corresponding slot 15 are connected by a second elastic member 17. A plurality of first teeth 18 are uniformly arranged on each driven plate 16, and a plurality of second teeth 19 are uniformly arranged on each straight plate 11. A transmission gear 20 is installed in each straight groove 12 through a positioning shaft. Each transmission gear 20 meshes with the first teeth 18 on its corresponding driven plate 16 and with the second teeth 19 on its corresponding straight plate 11.

[0042] Specifically, when the worker installs the grinding wheel body 2 onto the output shaft 1, the grinding wheel disc 9 on the grinding wheel body 2 pushes the driven plate 16 to slide towards one end of the slot 15, causing the driven plate 16 to compress the second elastic element 17 (the second elastic element 17 is a component capable of telescoping and resetting, preferably a spring), so that the second elastic element 17 is in a compressed state. At the same time, since the driven plate 16 is evenly provided with first teeth 18, and the first teeth 18 mesh with the transmission gear 20, when the driven plate 16 and the first teeth 18 slide towards one end of the slot 15, the driven plate 16 drives the transmission gear 20 to rotate around the positioning shaft through the first teeth 18. Since the transmission gear 20 meshes with the second teeth 19 on the straight plate 11, the transmission gear 20 drives the straight plate 11 to slide towards one end of the slot 15 within the straight groove 12, that is, the grinding wheel body 2 drives the driven plate 16 away from the nut 14. The driven plate 16 drives the straight plate 11 to move closer to the nut 14 via the transmission gear 20. This causes the straight plate 11 to drive the auxiliary rod 4 to slide closer to the grinding wheel body 2. The auxiliary rod 4 drives the positioning rod 5 and the clamping rod 7 to move to the edge of the grinding wheel disk 9, so that the grinding wheel disk 9 is pressed against the auxiliary shaft 3. Since the clamping rod 7 and the slide groove 6 are connected by the first elastic element 8 (the first elastic element 8 is a component that can extend and return, preferably a spring), the first elastic element 8 provides a certain elastic force to the clamping rod 7, so that the positioning rod 5 is pressed against the outer wall of the grinding wheel disk 9 (that is, the positioning rod 5 is pressed against the back of the cutter body 10 on the grinding wheel disk 9 under the drive of the driving element). This makes the clamping rod 7 provide a certain support force to the grinding wheel body 2, so that the grinding wheel body 2 is subjected to more uniform force when grinding materials, preventing damage caused by uneven force on the grinding wheel body 2, thereby improving the efficiency of material grinding.

[0043] In another embodiment of the present invention, a wedge plate 21 is provided on each of the two sides of each straight groove 12 on the auxiliary shaft 3, and a wedge surface 22 is provided on the side wall of each square groove 13 of the auxiliary rod 4. The two wedge plates 21 on the side of the same straight groove 12 and the two wedge surfaces 22 on the corresponding auxiliary rod 4 are wedge-shaped to each other; each straight plate 11 and the inner wall of the square groove 13 are connected by a third elastic member 23.

[0044] Specifically, during the process of the grinding wheel body 2 driving the driven plate 16 to slide away from the nut 14, the driven plate 16 drives the straight plate 11 to move closer to the nut 14 through the transmission gear 20. This causes the straight plate 11 to drive the auxiliary rod 4 to slide closer to the grinding wheel body 2. Since the side wall of the square groove 13 at the bottom of the auxiliary rod 4 is provided with a wedge-shaped surface 22, during the process of the straight plate 11 driving the auxiliary rod 4 to slide closer to the grinding wheel body 2, the wedge-shaped surface 22 and the wedge plate 21 on the auxiliary rod 4 are wedge-shaped and engage with each other. Under the pushing action of the wedge plate 21, the auxiliary rod 4 slides away from the output shaft 1. The auxiliary rod 4 drives the positioning rod 5 to slide away from the output shaft 1. The positioning rod 5 drives the pressing rod 7 to slide away from the output shaft 1 through the sliding groove 6. Since the straight plate 11 and the inner wall of the square groove 13 are connected by a third elastic element 23, the auxiliary rod 4 engages with the third elastic element 23. The elastic element 23 (the third elastic element 23 is a component capable of telescoping and resetting, preferably a spring) undergoes a certain stretching operation, so that the third elastic element 23 is in a stretched state. That is, during the sliding process of the straight plate 11 and the auxiliary rod 4 towards the end closer to the grinding wheel body 2, the auxiliary rod 4 drives the pressing rod 7 to slide away from the output shaft 1 through the positioning rod 5, so that the pressing rod 7 moves to a suitable position, so that the pressing rod 7 can press against the edge of the grinding wheel body 2. As those skilled in the art will know, the inclination angle of the inclined surface of each wedge plate 21 and the inclination angle of the wedge surface 22 on each auxiliary rod 4 can be adjusted according to the radius of the grinding wheel body 2, so as to ensure that the auxiliary rod 4 drives the pressing rod 7 to press against the edge of the grinding wheel body 2. That is, the inclination angle and inclination direction of the inclined surface of each wedge plate 21 and the wedge surface 22 on each auxiliary rod 4 can be adjusted (e.g., Figure 12 As shown, the inclination angle of the wedge plate 21 and the wedge surface 22 tilts upwards from the end closer to the grinding wheel body 2 to the end farther away from the grinding wheel body 2; this is the first state. Figure 13 As shown, the inclination angle of the wedge plate 21 and the wedge surface 22 is inclined downward from the end near the grinding wheel body 2 to the end away from the grinding wheel body 2 (this is the second state). As those skilled in the art will know, the grinding wheel body 2 used on the same angle grinder or grinding machine has the same specifications. The inclined surface of the wedge plate 21 and the wedge surface 22 on each auxiliary rod 4 can be adaptively adjusted according to the model of different angle grinders or grinding machines and the specifications of the grinding wheel body 2, so that the auxiliary rod 4 can drive the clamping rod 7 to move to the position of pressing against the edge of the grinding wheel body 2 under the clamping action of the wedge plate 21.

[0045] In another embodiment of the present invention, the center of the grinding wheel disk 9 is a circular groove. Multiple clearance grooves 24 are uniformly formed on the grinding wheel disk 9 along the circumferential direction of the circular groove. Multiple arc-shaped grooves 25 are uniformly formed on the grinding wheel disk 9 along its circumferential direction. The two ends of each arc-shaped groove 25 are interconnected with their adjacent clearance grooves 24. A limiting arc-shaped rod 26 is slidably disposed within each arc-shaped groove 25. Each limiting arc-shaped rod 26 and the inner wall of the arc-shaped groove 25 are connected by a fifth elastic element 27. Multiple locking blocks 28 are uniformly arranged along the circumferential direction on the portion of the output shaft 1 located between the nut 14 and the output shaft 1. Each locking block 28 and its corresponding clearance groove 24 are interlocked and engaged. Each locking block 28 abuts against two limiting arc-shaped rods 26 within the same clearance groove 24.

[0046] Specifically, since the existing connection between the grinding wheel body 2 and the output shaft 1 is mostly circular, when the grinding wheel body 2 rotates and grinds the material, the material is hard, causing the grinding wheel body 2 to remain stationary while the output shaft 1 rotates, thus preventing the grinding wheel body 2 from grinding the material. In this embodiment, the center of the grinding wheel body 2 is set as an annular groove, and multiple clearance grooves 24 are evenly arranged in the circumferential direction of the annular groove. A locking block 28 is set on the output shaft 1, so that the locking block 28 cooperates with the clearance groove 24. Since the limiting arc rod 26 and the inner wall of the arc groove 25 are each connected by a fifth elastic element 27, the limiting arc rod 26 is in a stationary state under the elastic force of the fifth elastic element 27 (the fifth elastic element 27 is an element that can extend and retract and return, preferably a spring). Figure 9 As shown), when the worker installs the grinding wheel disc 9 onto the output shaft 1, the worker mates the clearance groove 24 on the grinding wheel disc 9 with the locking block 28 on the output shaft 1, so that the end of the limiting arc rod 26 abuts against the end of the locking block 28. When the output shaft 1 drives the grinding wheel body 2 to grind the material, when the grinding wheel body 2 is pressed against the material, the output shaft 1 drives the locking block 28 to rotate a certain amount within the clearance groove 24 (that is, the grinding wheel body 2 will not rotate under the pressure of the material, while the output shaft 1 will rotate a certain amount, and the grinding wheel body 2 and the material will rotate). The output shaft 1 rotates to a certain extent until the locking block 28 abuts against the side wall of the relief groove 24. Due to the abutting action between the locking block 28 and the relief groove 24, the locking block 28 drives the grinding wheel body 2 to rotate through the relief groove 24, causing the grinding wheel body 2 to grind the material. At the same time, the locking block 28 drives the limiting arc rod 26 to rotate to a certain extent within the arc groove 25, causing the limiting arc rod 26 to perform a certain compression operation on the fifth elastic element 27, so that the fifth elastic element 27 is in a compressed state (e.g., Figure 10As shown), the two limiting arc rods 26 can clamp a locking block 28, ensuring that the locking block 28 is always in the limiting position. Through the mutual clamping and positioning between the locking block 28 and the relief groove 24, the grinding wheel body 2 and the output shaft 1 will not rotate freely when grinding the material, thus improving the stability of the grinding wheel body 2 in grinding the material.

[0047] In another embodiment of the present invention, each of the wedge plates 21 is provided with a positioning unit, and each positioning unit is used to position the auxiliary rod 4. The positioning unit includes a positioning plate 29. Each wedge plate 21 on the same side of the straight groove 12 is provided with a positioning plate 29. Each positioning plate 29 has a positioning groove 30. A triangular positioning block 31 is slidably disposed in each positioning groove 30. A driven rod 32 is connected to each triangular positioning block 31. A pushing groove 33 is provided on each driven rod 32. A square rod 34 is slidably installed in each pushing groove 33. Each square rod 34 and the inner wall of the corresponding pushing groove 33 are connected by a fourth elastic member 35.

[0048] Specifically, because the wedge plate 21 and the wedge surface 22 are wedge-shaped and engaged with each other, and the first elastic element 8 is in a compressed state, the auxiliary rod 4 will be subjected to the elastic force of the first elastic element 8, causing a tendency for relative sliding between the wedge plate 21 and the wedge surface 22. Positioning processing of the wedge plate 21 and the wedge surface 22 is required. During the process where the output shaft 1 drives the locking block 28 to rotate within the relief groove 24 until the locking block 28 abuts against the side wall of the relief groove 24, the output shaft 1 drives the positioning plate 29 to rotate through the wedge plate 21. Furthermore, because the driven rod 32 and the square rod 34 are connected by the fourth... The elastic element 35 (the fourth elastic element 35 is a component capable of telescopic return, preferably a spring) is connected. Under the elastic force of the fourth elastic element 35, the square rod 34 abuts against the side wall of the grinding wheel body 2. Since the grinding wheel body 2 provides a certain friction force to the square rod 34, the positioning plate 29 drives the driven rod 32 and the square rod 34 to rotate, causing the square rod 34 and the driven rod 32 to drive the triangular positioning block 31 to slide towards the end near the wedge plate 21, so that the triangular positioning block 31 moves to the end of the contact position of the wedge surface 22 of the wedge plate 21, so that the triangular positioning block... 31. The gap between the wedge surface 22 and the wedge plate 21 is positioned (that is, the triangular positioning block 31 is inserted into the gap between the wedge surface 22 and the wedge plate 21, so that the triangular positioning block 31 performs positioning work on the wedge surface 22 and the wedge plate 21), to prevent the auxiliary rod 4 and the wedge surface 22 from sliding on the wedge plate 21, thereby affecting the thrust provided by the auxiliary rod 4 and the clamping rod 7 to the grinding wheel body 2, and improving the stability of the position of the auxiliary rod 4 and the wedge surface 22 on the wedge plate 21. As those skilled in the art will know, even if the grinding wheel body 2 The friction provided to the square rod 34 does not cause the square rod 34 and the driven rod 32 to rotate, so the triangular positioning block 31 does not slide out of the positioning groove 30. However, by setting a groove on the grinding wheel disk 9 corresponding to the square rod 34, the groove on the grinding wheel disk 9 can position the square rod 34 to a certain extent. This ensures that when the grinding wheel disk 9 and the output shaft 1 rotate, the square rod 34 and the driven rod 32 can rotate with the output shaft 1, so that the square rod 34 and the driven rod 32 can drive the triangular positioning block 31 to position the gap between the wedge surface 22 and the wedge plate 21.

[0049] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
