[0002] As is known to all, the diamond grinding wheel is a type of diamond tool, which is mainly suitable for surface grinding processing of various refractory materials. The diamond grinding wheel is composed of a base and a cutter head, so that the electroplated diamond grinding wheel can maintain high precision and stability during use, and can improve the accuracy of the electroplated diamond grinding wheel in grinding materials. The diamond grinding wheel is installed on the output shaft of the angle grinder or grinder, and the angle grinder or grinder drives the diamond grinding wheel to rotate through the output shaft, so that the diamond grinding wheel can grind the material.

[0003] The production steps of the electroplated combined diamond grinding wheel are as follows: (1) Production of 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 wraps the diamond to form an electroplated diamond plate; (2) Cutting head processing: According to the shape of the grinding wheel substrate, the electroplated diamond plate is cut into the shape of the outer circle of the grinding wheel substrate by cutting equipment to produce the cutter head of the electroplated diamond grinding wheel; (3) Welding processing: Place the grinding wheel cutter head on the welding surface of the grinding wheel substrate by welding equipment, and obtain a complete electroplated combined diamond grinding wheel after welding is completed.

[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] An embodiment provided by the present invention relates to an electroplated combined diamond grinding wheel, comprising an output shaft 1 and a grinding wheel body 2, wherein the grinding wheel body 2 is mounted on the output shaft 1, and a plurality of cutter head bodies 10 are arranged on the end face of the grinding wheel body, wherein the cutter head body 10 comprises a metal plate body 101 and a diamond sheet body 102, and the two diamond sheet bodies 102 are connected on both sides of the same metal plate body 101. The thickness of the cutter head body 10 is adjustable, and the auxiliary unit also includes an auxiliary unit, wherein the auxiliary unit includes an auxiliary shaft 3, and the auxiliary shaft 3 is fixedly mounted on the output shaft 1, and a plurality of elastic telescopic extrusion rods are evenly arranged on the auxiliary shaft 3 along its circumferential direction, and the auxiliary shaft 3 and the plurality of elastic telescopic extrusion rods are in contact with the end face of the grinding wheel body 2 facing away from the cutter head body 10.

[0038] Specifically, the diamond grinding wheel is a device for grinding materials. The electroplated combined diamond grinding wheel is a diamond grinding wheel (i.e., the grinding wheel body 2) produced by electroplating treatment. The grinding wheel body 2 is divided into a grinding wheel disc 9 and a cutter head body 10. The grinding wheel disc 9 is fixedly connected to the output shaft 1 and abuts against the end of the auxiliary shaft 3. The outer wall edge of the grinding wheel disc 9 is evenly provided with a plurality of mounting grooves along its circumferential direction. A cutter head body 10 is welded in each mounting groove. The cutter head body 10 includes a metal plate body 101 and a diamond sheet body 102. The 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 the diamond sheet body 102. The two diamond sheet bodies 102 are connected to the metal plate body 101 by brazing, gluing or mechanical means (such as Figure 1As shown), heat dissipation grooves 103 are provided on both sides of the metal plate body 101 and the connection portion 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, and the heat dissipation groove 103 can generate heat by friction between the cutter head body 10 and the material for heat dissipation, thereby reducing the temperature of the cutter head body 10 during operation. The connecting surfaces of the two diamond sheet bodies 102 and the metal plate body 101 are welded in the mounting groove, and 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 through a metal plate body 101 in the middle, thereby realizing the thickness adjustment of the cutter head body 10 (as shown). Figure 2As shown), when the grinding wheel body 2 is grinding the material, the cutter head body 10 is in close contact with the material, so that the cutter head body 10 grinds the material. The cutter head body 10 can be a block-shaped arc structure, and each arc structure is an arc structure in the same rotation direction (that is, in the rotation direction of the output shaft 1). The cutter head body 10 can also be a block-shaped structure, which can 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 part (the power part is a device that can rotate, preferably a motor), or it can be directly used as the output shaft 1 of the power part. The end of the output shaft 1 is Threaded, the grinding wheel disc 9 is mounted on the output shaft 1 through a nut 14 and a washer. The auxiliary unit includes an auxiliary shaft 3, and the output shaft 1 is fixedly sleeved with an auxiliary shaft 3, that is, a section with a larger radial dimension is formed on the output shaft 1. The elastic telescopic extrusion rod includes an auxiliary rod 4, and a plurality of auxiliary rods 4 are evenly arranged on the auxiliary shaft 3 along its circumferential direction. A positioning rod 5 is provided at the end of each auxiliary rod 4, and a slide groove 6 is provided on each positioning rod 5. A tightening rod 7 is slidably installed in each slide groove 6, and each tightening rod 7 is connected to the inner wall of the corresponding slide groove 6 by a first elastic member 8. The auxiliary unit also includes a straight plate 11, and the outer wall of the auxiliary shaft 3 is along the upper edge. A plurality of straight grooves 12 are evenly opened in the circumferential direction, and a straight plate 11 is slidably installed in each straight groove 12. A square groove 13 is opened on each auxiliary rod 4, and a straight plate 11 is correspondingly 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 member (not shown in the figure). When the grinding wheel is assembled, the positioning rod 5 and the clamping rod 7 are pressed against the edge of the grinding wheel disc 9 (the side away from the cutter head body 10), and 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 is pressed against the auxiliary shaft 3. Since the first elastic member 8 (the first elastic member 8 is capable of The first elastic member 8 provides a certain elastic force for 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 head body 10 on the grinding wheel disc 9), so that the clamping rod 7 provides a certain supporting force for the grinding wheel body 2. When the grinding wheel body 2 grinds the material, the output shaft 1 drives the cutter head body 10 on the grinding wheel body 2 to grind the material. Under the clamping action of the clamping rod 7, the force on the grinding wheel body 2 when grinding the material is more uniform, preventing damage caused by uneven force on the grinding wheel body 2, thereby improving the efficiency of material grinding.

[0039] The deficiency 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 realize the grinding of the material. When the diamond grinding wheel is grinding the material, the cutter head on the edge of the diamond grinding wheel is tightly pressed against the material to grind the material. When the edge of the diamond grinding wheel is tightly pressed against the material for grinding, the edge of the diamond grinding wheel is easily broken or bent due to excessive force on the edge of the diamond grinding wheel, thereby causing damage to the diamond grinding wheel, thereby affecting the grinding efficiency and quality of the material.

[0040] The beneficial effect of this embodiment is that: when the grinding wheel body 2 is grinding 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 is pressed against the edge of the outer wall 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 evenly stressed, preventing damage caused by uneven stress on the grinding wheel body 2, and thereby improving the efficiency of material grinding.

[0041] In another embodiment provided by the present invention, a plurality of slots 15 are evenly provided on the auxiliary shaft 3 along its circumferential direction, and each of the slots 15 is communicated with its corresponding straight slot 12, and a driven plate 16 is slidably installed in each of the slots 15, and each of the driven plates 16 and the inner wall of the corresponding slot 15 is connected by a second elastic member 17; a plurality of first teeth 18 are evenly provided on each of the driven plates 16, and a plurality of second teeth 19 are evenly provided on each of the straight plates 11; a transmission gear 20 is installed in each of the straight slots 12 through a positioning shaft, and each of the transmission gears 20 is meshed with the first teeth 18 on the corresponding driven plate 16, and each of the transmission gears 20 is meshed with the second teeth 19 on the corresponding straight plate 11.

[0042] Specifically, when the staff is installing the grinding wheel body 2 on the output shaft 1, the grinding wheel disc 9 on the grinding wheel body 2 pushes the driven plate 16 to slide toward one end inside the slot 15, so that the driven plate 16 squeezes the second elastic member 17 (the second elastic member 17 is a component that can be telescopically reset, preferably a spring), so that the second elastic member 17 is in a compressed state. At the same time, since the first teeth 18 are evenly provided on the driven plate 16, and the first teeth 18 are meshed with the transmission gear 20, when the driven plate 16 and the first teeth 18 slide toward one end inside the slot 15, the driven plate 16 drives the transmission gear 20 to rotate with the positioning axis as the center through the first teeth 18. Since the transmission gear 20 and the second teeth 19 on the straight plate 11 are meshed with each other, the transmission gear 20 drives the straight plate 11 to slide in the straight groove 12 toward the outer end of the slot 15, that is, the grinding wheel body 2 drives the driven plate 16 to the end away from the nut 14 The cam 14 is pressed against the workpiece 11 and the cam 16 is engaged with the workpiece 11, and the cam 14 is engaged with the workpiece 11, and the cam 16 is engaged with the workpiece 11, and the cam 16 is engaged with the workpiece 11.

[0043] In another embodiment provided by the present invention, a wedge-shaped plate 21 is provided on each side of each straight groove 12 on the auxiliary shaft 3, and a wedge-shaped surface 22 is provided on the side wall of the square groove 13 of each 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-fitted with 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, in the process that the grinding wheel body 2 drives the driven plate 16 to slide toward the end away from the nut 14, the driven plate 16 drives the straight plate 11 to move toward the end close to the nut 14 through the transmission gear 20, so that the straight plate 11 drives the auxiliary rod 4 to slide toward the end close to the grinding wheel body 2. Since the side wall of the square groove 13 at the bottom end of the auxiliary rod 4 is provided with a wedge-shaped surface 22, in the process that the straight plate 11 drives the auxiliary rod 4 to slide toward the end close to the grinding wheel body 2, the wedge surface 22 on the auxiliary rod 4 and the wedge plate 21 cooperate with each other in a wedge shape. Under the pushing action of the wedge plate 21, the auxiliary rod 4 slides toward the end away from the output shaft 1, and the auxiliary rod 4 drives the positioning rod 5 to slide toward the end away from the output shaft 1. The positioning rod 5 drives the clamping rod 7 to slide toward the end 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 the third elastic member 23, the auxiliary rod 4 is pressed against the third elastic member 23. The elastic member 23 (the third elastic member 23 is a component capable of telescopic reset, preferably a spring) performs a certain stretching operation, so that the third elastic member 23 is in a stretched state, that is, in the process of the straight plate 11 and the auxiliary rod 4 sliding toward one end of the grinding wheel body 2, the auxiliary rod 4 drives the clamping rod 7 to slide toward the end away from the output shaft 1 through the positioning rod 5, so that the clamping rod 7 moves to a suitable position, so that the clamping rod 7 can be clamped against the edge position of the grinding wheel body 2. It is known to those skilled in the art that 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 clamping rod 7 to be clamped against the edge position of the grinding wheel body 2, that is, the inclined surface of each wedge plate 21 and the inclination angle and inclination direction of the wedge surface 22 on each auxiliary rod 4 can be adjusted (such as Figure 12 As shown, the inclination angle of the wedge plate 21 and the wedge surface 22 is inclined upward from the end close to the grinding wheel body 2 to the end away from the grinding wheel body 2, which is the first state; Figure 13 As shown, the inclination angles of the wedge plate 21 and the wedge surface 22 are inclined downward from the end close to the grinding wheel body 2 to the end away from the grinding wheel body 2, which is the second state). People skilled in the art will know that the specifications of the grinding wheel body 2 used on the same angle grinder or grinder are the same. 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 models of different angle grinders or grinders and the specifications of the grinding wheel body 2, so that the auxiliary rod 4 can drive the pressing rod 7 to move to a position that presses against the edge of the grinding wheel body 2 under the pressing action of the wedge plate 21.

[0045] In another embodiment provided by the present invention, the center position of the grinding wheel disc 9 is a circular groove body, and a plurality of clearance grooves 24 are evenly provided on the grinding wheel disc 9 in the circumferential direction of the circular groove body. A plurality of arc grooves 25 are evenly provided on the grinding wheel disc 9 along its circumferential direction, and the two ends of each arc groove 25 are respectively communicated with the adjacent clearance grooves 24. A limiting arc rod 26 is slidably provided in each arc groove 25, and each limiting arc rod 26 and the inner wall of the arc groove 25 are connected by a fifth elastic member 27. The part of the output shaft 1 located between the nut 14 and the output shaft 1 is evenly provided with a plurality of clamping blocks 28 along its circumferential direction. Each clamping block 28 is plugged into and matched with the corresponding clearance groove 24, and each clamping block 28 is respectively pressed against two limiting arc rods 26 in the same clearance groove 24.

[0046] Specifically, since the connection position between the existing grinding wheel body 2 and the output shaft 1 is mostly a circular structure, when the grinding wheel body 2 rotates and grinds the material, the grinding wheel body 2 is pressed against the material and the output shaft 1 rotates due to the hardness of the material, which causes the grinding wheel body 2 to be unable to grind the material. In this embodiment, the center of the grinding wheel body 2 is set as an annular groove body, and a plurality of clearance grooves 24 are evenly arranged in the circumferential direction of the annular groove body, and a clamping block 28 is provided on the output shaft 1 so that the clamping block 28 cooperates with the clearance groove 24. Since the limiting arc rod 26 and the inner wall of the arc groove 25 are connected by a fifth elastic member 27, the limiting arc rod 26 is in a stationary state (such as Figure 9 As shown), when the staff installs the grinding wheel disc 9 on the output shaft 1, the staff fits the clearance groove 24 on the grinding wheel disc 9 with the block 28 on the output shaft 1, so that the end of the limiting arc rod 26 and the block 28 abut against each other. When the output shaft 1 drives the grinding wheel body 2 to grind the material, when the grinding wheel body 2 and the material are pressed against each other for grinding, the output shaft 1 drives the block 28 to rotate to a certain extent in the clearance groove 24 (that is, the grinding wheel body 2 will not rotate under the action of the material, while the output shaft 1 rotates to a certain extent, and the grinding wheel body 2 and The output shaft 1 rotates to a certain extent until the clamping block 28 is pressed against the side wall of the clearance groove 24, so that the clamping block 28 is pressed against the side wall of the clearance groove 24. Due to the pressing effect between the clamping block 28 and the clearance groove 24, the clamping block 28 drives the grinding wheel body 2 to rotate through the clearance groove 24, so that the grinding wheel body 2 grinds the material. At the same time, the clamping block 28 drives the limiting arc rod 26 to rotate to a certain extent in the arc groove 25, so that the limiting arc rod 26 performs a certain extrusion operation on the fifth elastic member 27, so that the fifth elastic member 27 is in a compressed state (such as Figure 10As shown in the figure), the two limiting arc rods 26 can press against a clamping block 28, so that the clamping block 28 can always be in the limiting position. Through the mutual pressing and positioning between the clamping block 28 and the clearance groove 24, the grinding wheel body 2 and the output shaft 1 will not idle when grinding the material, thereby improving the stability of the grinding wheel body 2 in grinding the material.

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

[0048] Specifically, since the wedge plate 21 and the wedge surface 22 are wedge-shaped with each other, and the first elastic member 8 is in a compressed state, the auxiliary rod 4 will be subjected to the elastic force of the first elastic member 8, so that there is a tendency for relative sliding between the wedge plate 21 and the wedge surface 22, and the wedge plate 21 and the wedge surface 22 need to be positioned. When the output shaft 1 drives the block 28 to rotate in the clearance groove 24 until the block 28 is pressed against the side wall of the clearance groove 24, the output shaft 1 drives the positioning plate 29 to rotate through the wedge plate 21, and since the driven rod 32 and the square rod 34 are connected by the fourth The fourth elastic member 35 is connected to the square rod 34 under the elastic force of the fourth elastic member 35. The square rod 34 is pressed against the side wall of the grinding wheel body 2. Since the grinding wheel body 2 provides a certain friction force for the square rod 34, the positioning plate 29 drives the driven rod 32 and the square rod 34 to rotate, so that the square rod 34 and the driven rod 32 drive the triangular positioning block 31 to slide toward one end of the wedge plate 21, so that the triangular positioning block 31 moves to the end of the abutment position of the wedge surface 22 of the wedge plate 21, so that the triangular positioning block The triangular positioning block 31 is inserted into the gap between the wedge surface 22 and the wedge plate 21 to position the wedge surface 22 and the wedge plate 21, thereby preventing 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 holding 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. It is known to those skilled in the art that even if the grinding wheel body 2 The friction force provided for the square rod 34 does not drive the square rod 34 and the driven rod 32 to rotate, so that the triangular positioning block 31 does not slide out of the positioning groove 30. It is also possible to provide a groove corresponding to the square rod 34 on the grinding wheel disc 9 so that the groove on the grinding wheel disc 9 can position the square rod 34 to a certain extent, ensuring that when the grinding wheel disc 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.
