Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheels, in particular to a diamond grinding wheel. Background Art

[0002] Diamond grinding wheel is a high-performance abrasive tool that uses artificial diamond as abrasive. It is composed of diamond abrasive grains, binder and matrix. Diamond abrasive grains are the main working part of the grinding wheel, responsible for cutting and grinding workpieces; the binder is used to fix the diamond abrasive grains on the grinding wheel matrix; the matrix is the supporting structure of the grinding wheel.

[0003] As a high-performance abrasive tool, diamond grinding wheels have standardized control over their wear state. When the wear state of diamond grinding wheels exceeds the standardized range, new diamond grinding wheels need to be replaced. However, since the wear of diamond grinding wheels only occurs on the diamond layer of the working part, and even the different parts of the diamond layer that contact the workpiece may cause different wear states in different parts of the diamond layer, replacing the entire diamond wheel will increase costs invisibly, and it is not conducive to the optimal use of resources.

[0031] Please refer to Figure 1 , the present invention provides a diamond grinding wheel, including a substrate 1 and a diamond layer assembly 2 assembled on the substrate 1. Combining Figure 1 and Figure 2 , an installation groove 12 is inwardly formed on the upper surface of the substrate 1, and a locking assembly 3 is installed in the installation groove 12; specifically, combining Figures 2 to 4 as shown, the locking assembly 3 includes a gear 31 installed in the installation groove 12 and an L-shaped toothed plate 32 meshed with the gear 31; specifically, the L-shaped toothed plate 32 includes a toothed driving plate 321 meshed with the gear 31, a driven plate 322 fixedly connected to the driving plate 321 and forming an "L" shape with the driving plate 321, and an L-shaped locking piece 323 fixedly connected to the driven plate 322. Returning to Figure 2 and Figure 3, a slot 11 is formed inward on the outer peripheral surface of the base body 1, and the slot 11 is located below the installation groove 12, that is, the installation groove 12 is located above the slot 11; avoidance grooves 13 perpendicular to the advancing direction of the slot 11 and penetrating the slot 11 and the installation groove 12 are formed on the inner walls of the two sides of the advancing direction of the slot 11. The active plate 321 is arranged perpendicular to the advancing direction of the slot 11, the driven plate 322 is arranged parallel to the advancing direction of the slot 11 and is connected to the inner wall of the installation groove 12 through a reset member 4. Specifically, the reset member 4 in this embodiment is a reset spring, and there are 2 reset springs which are respectively connected to both ends of the driven plate 322. The L-shaped locking member 323 passes through the installation groove 12 and enters the slot 11. Specifically, when the reset member 4 is compressed and deformed, the locking member 323 moves into the avoidance groove 13, and when the reset member 4 remains in its original state, the locking member 323 is inserted into the diamond layer assembly 2.

[0032] Refer to Figure 3 , the diamond layer assembly 2 includes a diamond layer 21 adapted to the outer peripheral surface of the base body 1 and closely attached to each other, and a plug board 22 fixedly assembled with the diamond layer 21 and inserted into the slot 11 to realize the connection between the base body 1 and the diamond layer assembly 2. Locking grooves 221 are formed inward on the two side surfaces of the advancing direction of the plug board 22. Specifically, the diamond layer assembly 2 is inserted into the slot 11 through the plug board 22, and when the reset member 4 returns to its original state, it drives the locking member 323 to be inserted into the locking groove 221 to realize the connection between the diamond layer assembly 2 and the base body 1. The diamond layer 21 is adapted to the outer peripheral surface of the base body 1, and adjacent diamond layers 21 are closely attached to form a whole; in this embodiment, the number of the diamond layer assemblies 2 is set to 4, and the 4 diamond layer assemblies 2 surround the outer periphery of the base body 1 and form a whole with the base body 1.

[0033] To strengthen the connection between the diamond layer assembly 2 and the base body 1, connection grooves 14 are symmetrically formed on both sides of the outer peripheral surface of the base body 1 where the slot 11 is located, and the diamond layer 21 is fixedly assembled with connectors 23 corresponding to and adapted to the connection grooves 14. When the diamond layer assembly 2 is installed, while the plug board 22 is inserted into the slot 11, the connectors 23 are inserted into the connection grooves 14 to strengthen the connection between the diamond layer assembly 2 and the base body 1.

[0034] To avoid hard collisions when the plug board 22 is inserted into the slot 11 and hard collisions when the workpiece has a high hardness during work, please refer to Figure 3 , a buffer member 5 is arranged at the bottom end of the advancing direction of the slot 11. Specifically, the buffer member 5 includes a buffer plate 51 and buffer connectors 52 connecting the buffer plate 51 and the inner wall of the bottom end of the slot 11. Specifically, the buffer connectors 52 in this embodiment are buffer springs and there are two buffer springs which are respectively connected to both ends of the buffer plate 51. When the plug board 22 is inserted into the slot 11 or the workpiece has a high hardness, the buffer member 5 provides a buffer force to give the diamond layer assembly 2 a corresponding buffer space, avoiding damage to the diamond layer assembly 2 caused by hard collisions.

[0035] Please refer toFigure 1 and Figure 4 At the opening of the installation groove 12, a cover plate 6 forming a groove with the upper surface of the base body 1 is provided. A knob 7 passing through the cover plate 6 is fixedly connected to the rotating shaft of the gear 31. Specifically, when a force is applied to the knob 7, the knob 7 transmits the force to the gear 31, thereby driving the L-shaped toothed plate 32 to move. When the L-shaped toothed plate 32 moves, it squeezes the reset member 4 to cause it to be compressed and deformed. When the force on the knob 7 is removed, the reset member 4 releases the compressive force for restoring deformation to the L-shaped toothed plate, so that the L-shaped toothed plate 32 drives the gear 31 to drive the knob 7 to return to the initial position.

[0036] The application process of a diamond grinding wheel provided by an embodiment of the present application is as follows: During assembly, a force is applied to the knob 7 to transmit the force to the gear 31. The gear 31 rotates and drives the engaged L-shaped toothed plate 32 to move close to the inner wall of the installation groove 12. While moving, the driven plate 322 squeezes the reset member 4, causing the reset member 4 to be compressed and deformed. At this time, the L-shaped locking member 323 moves along with the driven plate 322 and moves into the avoidance groove 13. At this time, the insertion plate 22 of the diamond layer 21 assembly 2 is inserted into the insertion slot 11. When the external force on the knob 7 is removed, the reset member 4 releases the compressive force for restoring deformation, pushes the L-shaped toothed plate 32 to move away from the inner wall of the installation groove 12, and at the same time drives the gear 31 to rotate to drive the knob 7 to return to the initial position. The L-shaped locking member 323 moves along with the driven plate 322 and is inserted into the locking groove 221 of the insertion plate 22, realizing the connection between the diamond layer assembly 2 and the base body 1. At the same time, the connecting member 23 of the diamond layer assembly 2 is inserted into the connecting groove 14 while the insertion plate 22 is inserted into the insertion slot 11. After all the diamond layer assemblies 2 are connected, the adjacent diamond layers 21 are closely attached to form an integral body. At this time, the assembly of the diamond grinding wheel is completed. Then, it is connected to mechanical equipment such as a grinding machine through the base body 1, and the workpiece is processed under the drive of the mechanical equipment. When it is detected that the wear rate of a certain part of the diamond layer 21 or the overall diamond layer 21 exceeds the standard range, the replacement work of the diamond layer 21 is carried out. Specifically, a force is applied to the knob 7 to rotate the gear 31, driving the engaged L-shaped toothed plate 32 to move close to the inner wall of the installation groove 12. While moving, the driven plate 322 squeezes the reset member 4, causing the reset member 4 to be compressed and deformed. At this time, the L-shaped locking member 323 moves along with the driven plate 322 and moves into the avoidance groove 13, releasing the connection between the diamond layer assembly 2 and the base body 1. The diamond layer 21 assembly 2 can be pulled out from the insertion slot 11, and then a new diamond layer 21 assembly 2 can be replaced as in the above installation steps.

[0037] The diamond grinding wheel provided by the present application has the advantages that the corresponding diamond layer 21 can be replaced according to the specific wear condition, and the replacement operation is simple, reducing the application cost and improving the optimal application of resources.

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 made 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.
