Description

Technical Field

[0001] This utility model relates to the field of abrasive and grinding tool technology, and specifically to an abrasive and grinding tool with good wear resistance. Background Technology

[0002] In grinding, abrasives or grinding wheels are commonly used as grinding tools to machine parts to meet certain technical requirements. Existing grinding wheels improve wear resistance by adding mixed fillers. However, the matrix layer on the outside of the grinding wheel base is a single piece. Therefore, when the matrix layer wears down to the point of being unusable, a new grinding wheel needs to be replaced, and the original grinding wheel base will be disassembled and discarded, resulting in waste. Therefore, this utility model provides an abrasive grinding wheel with good wear resistance to solve the above problems.

[0003] To address the aforementioned technical problems, Chinese Patent No. CN221111304U discloses an abrasive tool with good wear resistance, comprising a tool base, a baffle connected to the bottom surface of the tool base, a connecting ring connected to the top surface of the baffle, a wear-resistant layer connected to the outer surface of the connecting ring, and a first bolt penetrating the bottom surface of the baffle, with one end of the first bolt extending into a first fixing hole opened on the bottom surface of the tool base.

[0004] While the aforementioned existing technical solutions allow operators to replace severely worn wear-resistant layers, the disassembly and assembly operations required when replacing the wear-resistant layers, baffles, and connecting rings all necessitate workers to twist each set of bolts on both sides one by one for connection. This is cumbersome and time-consuming, increasing the workload of workers and consequently reducing work efficiency. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A wear-resistant abrasive tool includes a connecting seat 1, a support 2 overlapping the bottom end of the connecting seat 1, and a wear-resistant ring 3 installed on the outer side of the support 2. The connecting seat 1 is engaged with the support 2 via a pressing mechanism. An extension groove is provided on one side of the outer wall of the connecting seat 1 near the top. A rubber pad 4 is embedded in the bottom end of the connecting seat 1. The pressing mechanism includes a docking component, an abutting component, and an intercepting component. The docking component is used to initially dock the connecting seat 1 and the support 2. The abutting component is used to lock the positions of the connecting seat 1 and the support 2. The intercepting component is used to prevent accidental contact with the operating components from causing the connection to loosen. In use, the connecting seat 1 and the support 2 can be initially docked by the docking component, the positions of the connecting seat 1 and the support 2 can be locked by the abutting component, and the intercepting component prevents accidental contact with the operating components from causing the connection to loosen. The structure is simple and easy to operate. When the operator needs to replace it, they only need to press and pull to quickly replace the severely worn wear-resistant ring 3, reducing the workload of the operator and improving work efficiency.

[0025] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the docking assembly includes a through hole installed at one end of the rubber pad 4. A docking block 5 is installed on the inner side of the support 2 corresponding to the through hole. The bottom end of the connecting seat 1 has a docking groove that is slidably connected to the docking block 5. The docking block 5 and the docking groove are slidably connected. An installation groove is provided inside the connecting seat 1 on one side of the docking groove. First, when locking the connecting seat 1, it can be initially overlapped with the support 2, allowing the docking block 5 to enter the inner side of the docking groove. When continuously pressed, the rubber pad 4 is compressed.

[0026] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, limit seats 6 are installed at both ends of the inner wall of the mounting groove. A first limit groove is formed at the top of the limit seat 6. A first limit block 7 is slidably connected to the inner side of the first limit groove. A first spring 8 is installed between the first limit block 7 and the inner wall of the first limit groove. The abutment assembly includes a pressing block 9 installed at the other end of the first limit block 7. The opposite ends of the two sets of pressing blocks 9 and the docking block 5 are provided with a first slope 10 that fits against each other. A retraction groove is formed inside the pressing block 9 at the first slope 10. A retraction rod is rotatably connected to the inner side of the retraction groove. A retraction plate 11 is sleeved on the outer side of the retraction rod. A second slope that fits against the first slope 10 is formed on one side of the retraction plate 11. A torsion spring 12 is installed between one end of the retraction rod and the inner wall of the retraction groove. Both ends of the docking block 5 are provided with abutment grooves. Then, the docking block 5 contacts the two sets of extrusion blocks 9, and the opposing first slopes 10 press against each other. The first limiting block 7 moves along the inside of the first limiting groove and presses the first spring 8. The docking block 5 continues to press down and contacts the retraction plate 11. The first slope 10 presses against the second slope, forcing the retraction plate 11 to drive the retraction rod to press the torsion spring 12 to retract until the abutment groove is aligned with the retraction groove. Then, the retraction plate 11 is popped out by the torsion spring 12. At this time, the connecting seat 1 is released, and the rubber pad 4 rebounds and drives the abutment groove to abut against one end of the retraction plate 11, completing the locking.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a groove is provided on one side of the extrusion block 9, and a pull rod 13 is installed inside the groove. The pull rod 13 is slidably connected to the connecting seat 1. The end of the pull rod 13 extending to the inside of the extension groove is rotatably connected to a pull ring 14. Furthermore, when it is necessary to unlock the lock between the connecting seat 1 and the support 2, the buckle ring 17 can be fastened first to drive the second fixing plate to move upward. At the same time, the two sets of intercepting rods 18 slide upward. After moving away from the two sets of pull rods 13, the two sets of pull rods 13 can be pried apart in opposite directions, allowing the two sets of extrusion blocks 9 to actively move away from the docking block 5. The retraction plate 11 on it also moves away from the inside of the abutment groove and releases the abutment state. At this time, the rubber pad 4 rebounds due to its characteristics, and the docking block 5 rises a certain distance. At this time, the pull rod 13 will no longer be controlled and there will be no re-locking situation.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the interception assembly includes a first fixing plate 15 installed at one end of the top of the connecting seat 1. Positioning springs 16 are installed at both ends of one side of the first fixing plate 15. A second fixing plate is installed at the other end of the two sets of positioning springs 16. A buckle 17 is installed on one side of the second fixing plate. Two sets of interception rods 18 are installed on the other side of the second fixing plate. One end of the interception rod 18 extends into the inside of the extension groove. The interception rod 18 is slidably connected to the connecting seat 1. Furthermore, after relocking, the buckle 17 can be released to allow the positioning springs 16 to drive the two sets of interception rods 18 into the inside of the extension groove to block the pull rod 13 and prevent the pull rod 13 from slipping and accidentally touching, causing the component connection to become loose.

[0029] The implementation principle of the wear-resistant abrasive tool in this application embodiment is as follows: When locking the connecting seat 1, it can be initially overlapped with the support 2, allowing the mating block 5 to enter the mating groove. When continuously pressed, the rubber pad 4 is compressed, and the mating block 5 contacts the two sets of extrusion blocks 9. The opposing first slopes 10 press against each other, and the first limiting block 7 moves accordingly inside the first limiting groove and presses the first spring 8. When the mating block 5 continues to press down, it contacts the retraction plate 11. The first slope 10 presses against the second slope, forcing the retraction plate 11 to drive the retraction rod to press the torsion spring 12 to retract until the abutment groove is aligned with the retraction groove. Then, the retraction plate 11 is ejected by the torsion spring 12. At this time, the connecting seat 1 is released, and the rubber pad 4 rebounds, causing the abutment groove to abut against one end of the retraction plate 11, completing the locking. When the wear-resistant ring 3 has been used for a period of time... In cases of severe wear, when it is necessary to unlock the connection between the connecting seat 1 and the support 2, first fasten the buckle 17 to move the second fixing plate upward, while simultaneously sliding the two sets of intercepting rods 18 upward. After moving away from the two sets of pull rods 13, the two sets of pull rods 13 can be pried apart in opposite directions, allowing the two sets of pressing blocks 9 to actively move away from the mating block 5. The retraction plate 11 on it will also move away from the inner side of the abutment groove, releasing the abutment state. At this time, the rubber pad 4 rebounds due to its characteristics, and the mating block 5 rises a certain distance. At this point, even if the pull rod 13 is no longer controlled, there will be no re-locking. After relocking, the buckle 17 can be released to allow the positioning spring 16 to drive the two sets of intercepting rods 18 into the inner side of the extension groove, blocking the pull rod 13 and preventing the pull rod 13 from sliding and accidentally touching, causing the component connection to loosen.

The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
