Description

Technical Field

[0001] This utility model relates to the field of diamond abrasives, and more particularly to a modular diamond abrasive. Background Technology

[0002] Diamond grinding tools are manufactured using different binders and diamond abrasives. They are mainly used for grinding, polishing, and grinding materials such as cemented carbide and stone. With their excellent hardness and sharpness, low grinding temperature due to high thermal conductivity, excellent wear resistance and long service life, high precision machining capabilities, and wide adaptability, diamond grinding tools have become efficient, reliable, and multifunctional grinding tools. They are particularly suitable for precision machining of hard materials, significantly improving machining efficiency and workpiece quality.

[0003] Traditional diamond grinding wheels typically consist of a single, integrated grinding head. However, during use, this head wears down, often requiring complete replacement. In contrast, existing technology offers a partially replaceable diamond grinding wheel. For example, Chinese Patent Application No. CN202322218840.2 discloses a modular diamond grinding wheel. This utility model discloses a modular diamond grinding wheel, belonging to the field of grinding wheel technology. It includes a mounting plate and several grinding blocks. The mounting plate has several stop openings arranged in a ring around the mounting plate, allowing grinding blocks to be inserted. The length direction of the stop openings is aligned with the diameter direction of the mounting plate. The mounting plate is movably equipped with a control component that allows multiple grinding blocks to be inserted simultaneously into the stop openings. This modular diamond grinding wheel ensures the stability of the connection between the grinding blocks and the mounting plate while increasing the convenience of replacing grinding blocks.

[0004] However, the above technology has the following problems: the mounting plate only fixes the grinding block through the metal braided strip in the second limiting groove. The two ends of the metal braided strip are fixed in the second limiting groove by the pull head one and pull head two. The metal braided strip will inevitably undergo inelastic deformation under long-term tension, which will lead to the risk of the grinding block falling out. In addition, it is difficult to achieve zero tolerance between the grinding block and the first limiting groove. The grinding block will inevitably loosen to a certain extent in the first limiting groove. Therefore, it is very unsafe to fix the grinding block in the first limiting groove only by the metal braided strip. Additional fixing measures are required to ensure the safe use of the grinding tool. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes a modular diamond abrasive tool, which can solve the problem of insufficiently secure fixing of the abrasive block in the prior art.

[0006] A modular diamond abrasive tool includes a mounting plate on which a plurality of grinding blocks for grinding are mounted. The mounting plate has a mounting hole in the center. The mounting plate is mounted to a rotating device through the mounting hole. The rotating device drives the mounting plate to rotate about its own axis.

[0007] The mounting plate has several mounting slots on its side, and the bottom surface of the mounting slot is parallel to the top surface of the mounting plate. The slot opening extends from the side of the mounting plate to the top surface of the mounting plate. The slot openings on the side and top of the mounting plate are the side opening and the top opening, respectively. The grinding block can be inserted into the mounting slot from the side opening along the slot. After the grinding block is inserted, a part of the grinding block protrudes from the top opening along the axis of the mounting plate.

[0008] The mounting slots are evenly distributed on the mounting plate with the axis of the mounting plate as the center, and the mounting slots do not interfere with each other. The mounting slots do not interfere with the mounting holes.

[0009] The mounting plate is provided with a primary locking mechanism on both sides of the groove on the top surface. The primary locking mechanism can initially lock the grinding block after it is inserted into the mounting groove to prevent the grinding block from shifting.

[0010] The side opening of the mounting groove is provided with a secondary locking mechanism, which can further fix the grinding block and prevent the grinding block from coming out of the side opening.

[0011] Furthermore, the cross-section of the mounting groove perpendicular to the axis of the mounting plate is fan-shaped, the arc edge of the fan-shaped groove coincides with the arc edge of the outer periphery of the mounting plate, and the axis of symmetry of the fan-shaped groove intersects with the axis of the mounting plate. The cross-section of the grinding block perpendicular to the axis of the mounting plate matches the cross-section of the mounting groove perpendicular to the axis of the mounting plate.

[0012] Furthermore, the top surface opening is provided with a flange that protrudes inward parallel to the top surface of the mounting plate at the edge near the top surface of the mounting plate. The flange can hold the grinding block in the mounting groove, so that the grinding block cannot move in the mounting groove in a direction perpendicular to the top surface of the mounting plate.

[0013] Furthermore, locking holes are provided on both sides of the grinding block that contact the two sides of the mounting groove. The axis of the locking hole is parallel to the top surface of the mounting plate and perpendicular to the two sides of the mounting groove. The first-level locking mechanism includes movable holes opened on the two sides of the mounting groove. The axis of the movable hole is parallel to the top surface of the mounting plate. A locking pin is coaxially arranged in the movable hole. A spring is arranged between the locking pin and the end face of the movable hole. The spring can push the locking pin into the locking hole. After the locking pin is pushed into the locking hole, a part of it is still in the movable hole, so that the grinding block cannot move along the groove.

[0014] Furthermore, a movable rod is coaxially fixedly connected to the side of the locking pin away from the grinding block. A movable groove with an opening facing the top surface of the mounting plate is provided on the end face of the movable hole away from the grinding block. The movable rod protrudes from the movable groove through the end face. A trigger is provided at one end of the movable rod located in a part of the movable groove. The trigger protrudes from the top surface of the mounting plate. Pulling the trigger in the movable groove to move away from the grinding block can move the locking pin toward the end face of the movable hole, thereby releasing the locking of the grinding block. The trigger can also be locked on the end face of the movable groove near the movable hole to prevent the locking pin from being ejected from the movable hole by the spring.

[0015] Furthermore, the movable slot is disposed between two mounting slots, and both ends of one movable slot are simultaneously penetrated by movable rods. Both ends of the movable rods away from their respective connected locking pins are provided with triggers. The movable slot can accommodate the stroke of two triggers simultaneously pulling the locking pins connected on both sides back into the movable hole.

[0016] Furthermore, a first threaded hole is provided at the bottom of the movable groove. The axis of the first threaded hole is perpendicular to the top surface of the mounting plate. When the trigger is not pulled, it abuts against the two end faces of the movable groove under the action of the spring. A detachable fixing block is provided between the triggers. The fixing block is provided with a second threaded hole. When the first threaded hole and the second threaded hole are coaxial, a bolt can be coaxially screwed into the first threaded hole and the second threaded hole to fix the fixing block. After the fixing block is fixed in the movable groove, the trigger can be fixed and cannot be pulled, thereby fixing the locking pin in the locking hole.

[0017] Furthermore, after the grinding block is installed into the mounting groove, the outer edge of the grinding block is flush with the outer periphery of the mounting plate, and a pair of third threaded holes are provided on both sides of the side opening of the mounting plate. The axis of the third threaded hole intersects and is perpendicular to the axis of the mounting plate. A fixing baffle is installed on the side opening, and a pair of fourth threaded holes are provided on the fixing baffle. Bolts can be coaxially screwed into the third threaded holes and the fourth threaded holes, thereby fixing the fixing baffle on the side opening and further locking the grinding block.

[0018] This utility model has the following advantages: the grinding block is initially fixed by the locking pins set on both sides of the mounting groove, and the locking pins can be moved relatively easily and quickly, which facilitates the installation of the grinding block. On this basis, the trigger at one end of the locking pin can be further fixed by the fixing block, which further strengthens the locking firmness of the grinding block. In addition, the fixing baffle set on the side opening also further fixes the grinding block. With the cooperation of the first-level locking mechanism and the second-level locking mechanism, the problem of insufficient fixing of the grinding block in the prior art is solved, and the installation of the grinding block is relatively simple.

[0024] The present invention will now be described with reference to the accompanying drawings:

[0025] like Figure 1 As shown, a modular diamond abrasive tool includes a mounting plate 1, on which a plurality of grinding blocks 2 for grinding are mounted, and a mounting hole 3 is provided in the center of the mounting plate 1. The mounting plate 1 is mounted to a rotating device through the mounting hole 3, and the rotating device drives the mounting plate 1 to rotate about its own axis.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, the mounting plate 1 has several mounting grooves 4 on its side, and the bottom surface of the groove 4 is parallel to the top surface 5 of the mounting plate. The groove opening of the mounting groove 4 extends from the side of the mounting plate 1 to the top surface 5 of the mounting plate 1. The groove openings of the mounting groove 4 on the side and top surface 5 of the mounting plate 1 are the side opening 6 and the top opening 7, respectively. The grinding block 2 can be inserted into the mounting groove 4 from the side opening 6 along the groove. After the grinding block 2 is inserted, a part of the grinding block 2 protrudes from the top opening 7 along the axial direction of the mounting plate 1.

[0027] like Figure 1 As shown, several mounting slots 4 are evenly distributed on the mounting plate 1 with the axis of the mounting plate 1 as the center, and each mounting slot 4 will not interfere with each other, and the mounting slots 4 will not interfere with the mounting holes 3.

[0028] like Figure 1 As shown, a primary locking mechanism is provided on both sides of the groove on the top surface 5 of the mounting plate. The primary locking mechanism can initially lock the grinding block 2 after it is inserted into the mounting groove 4 to prevent the grinding block 2 from shifting.

[0029] like Figure 1 , Figure 4As shown, the side opening of the mounting groove 4 is provided with a secondary locking mechanism, which can further fix the grinding block 2 and prevent the grinding block 2 from coming out of the side opening 6.

[0030] like Figure 1 , Figure 4 As shown, preferably, the cross-section of the mounting groove 4 perpendicular to the axis of the mounting disk 1 is fan-shaped, the arc edge of the fan-shaped groove coincides with the arc edge of the outer periphery of the mounting disk 1, and the axis of symmetry of the fan-shaped groove intersects with the axis of the mounting disk 1. The cross-section of the grinding block 2 perpendicular to the axis of the mounting disk 1 matches the cross-section of the mounting groove 4 perpendicular to the axis of the mounting disk 1.

[0031] like Figure 1 , Figure 4 As shown, preferably, the top surface opening 7 is provided with a flange 8 that protrudes inward parallel to the top surface 5 of the mounting plate near the edge of the mounting plate top surface 5. The flange 8 can hold the grinding block 2 in the mounting groove 4, so that the grinding block 2 cannot move in the mounting groove 4 in a direction perpendicular to the top surface 5 of the mounting plate.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, preferably, locking holes 9 are provided on the two sides of the grinding block 2 that contact the two sides of the mounting groove 4. The axis of the locking holes 9 is parallel to the top surface 5 of the mounting plate and perpendicular to the two sides of the mounting groove 4. The first-level locking mechanism includes movable holes 10 opened on the two sides of the mounting groove 4. The axis of the movable holes 10 is parallel to the top surface 5 of the mounting plate. A locking pin 11 is coaxially arranged in the movable holes 10. A spring 12 is arranged between the locking pin 11 and the end face of the movable holes 10. The spring 12 can push the locking pin 11 into the locking holes 9. After the locking pin 11 is pushed into the locking holes 9, a part of it is still located in the movable holes 10, so that the grinding block 2 cannot move along the groove.

[0033] like Figure 1 , Figure 2 , Figure 4 As shown, preferably, the locking pin 11 is coaxially fixedly connected to a movable rod 13 on the side away from the grinding block 2. The movable hole 10 has a movable groove 14 with an opening facing the top surface 5 of the mounting plate on the side away from the grinding block 2. The movable rod 13 protrudes through the end face and into the movable groove 14. A trigger 15 is provided at one end of the movable rod 13 located in a part of the movable groove 14. The trigger 15 protrudes from the top surface 5 of the mounting plate. Pulling the trigger 15 in the movable groove 14 to move away from the grinding block 2 can move the locking pin 11 toward the end face of the movable hole 10, thereby releasing the locking of the grinding block 2. The trigger 15 can also be stuck on the end face of the movable groove 14 near the movable hole 10 to prevent the locking pin 11 from being ejected from the movable hole 10 by the spring 12.

[0034] like Figure 1 and Figure 2 As shown, preferably, the movable groove 14 is disposed between two mounting grooves 4, and both ends of one movable groove 14 are simultaneously penetrated by movable rods 13. Both ends of the movable rods 13 away from their respective connected locking pins 11 are provided with triggers 15. The movable groove 14 can accommodate the stroke of the two triggers 15 simultaneously pulling the locking pins 11 connected on both sides back into the movable hole 10.

When the trigger 15 is not pulled, it abuts against the two end faces of the movable groove 14 under the action of the spring 12. A detachable fixing block 16 is provided between the triggers 15. The fixing block 16 is provided with a second threaded hole 18. When the first threaded hole 17 and the second threaded hole 18 are coaxial, a bolt can be coaxially screwed into the first threaded hole 17 and the second threaded hole 18, thereby fixing the fixing block 16. After the fixing block 16 is fixed in the movable groove 14, the trigger 15 can be fixed and cannot be pulled, thereby fixing the locking pin 11 in the locking hole 9.

[0036] like Figure 1 and Figure 4 Preferably, after the grinding block 2 is installed into the mounting groove 4, the outer edge of the grinding block 2 is flush with the outer periphery of the mounting plate 1, and a pair of third threaded holes 19 are provided on both sides of the side opening 6 of the mounting plate 1. The axis of the third threaded hole 19 intersects and is perpendicular to the axis of the mounting plate 1. A fixing baffle 21 is installed on the side opening 6. A pair of fourth threaded holes 20 are provided on the fixing baffle 21. Bolts can be coaxially screwed into the third threaded holes 19 and the fourth threaded holes 20, thereby fixing the fixing baffle 21 to the side opening 6 and further locking the grinding block 2.

[0037] It should be noted that the rotating device mentioned in this utility model can be a motor or other device that can rotate the mounting plate 1. This utility model does not limit the rotating device used, and the side of the grinding block 2 away from the mounting groove 4 is the grinding surface. The grinding block 2 can be replaced according to the usage.

[0038] The method of using this utility model is as follows: During installation, the grinding block 2 is inserted into the groove from the side opening 6. When inserted, since the cross-section of the mounting groove 4 of the grinding block 2 perpendicular to the axis of the mounting plate 1 is fan-shaped, the two sides of the grinding block 2 can push the locking pin 11 back into the movable hole 10. When the locking pin 11 corresponds to the locking hole 9, the locking pin 11 is ejected and pushed into the locking hole 9 under the action of the spring 12. At this time, the movable rod 13 drives the trigger 15 to move towards the two end faces of the movable groove 14. After the trigger 15 abuts against the two end faces of the movable groove 14, the fixing block 16 is placed... The grinding block 2 is initially fixed by inserting it into the movable groove 14 and fixing the fixing block 16 by coaxially screwing bolts into the first threaded hole 17 and the second threaded hole 18. The fixing block 16 limits the trigger 15. Then, the grinding block 2 is initially fixed by coaxially screwing bolts into the side opening 6 to install the fixing baffle 21. The fixing is then completed. When disassembling, the fixing block 16 needs to be removed from the movable groove 14 and the fixing baffle 21 also needs to be removed. Then, the trigger 15 is pulled to release the locking pin 11 from the locking hole 9, and the grinding block 2 can be taken out.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
