Description

Technical Field

[0001] This utility model relates to the field of diamond abrasive technology, specifically to a diamond abrasive made of wear-resistant composite material. Background Technology

[0002] Diamond and alloy composite abrasives are widely used in metal processing industries such as machinery manufacturing, as well as in the processing of non-metallic materials such as ceramics, glass, and stone. They are used for grinding and polishing material surfaces. Abrasives made from diamond and alloy composite materials are a type of artificial abrasive, specifically made by combining diamond abrasive with a high-strength alloy binder.

[0003] In the prior art, such as Chinese Patent Publication No. CN217943052U, a diamond grinding tool that is easy to change quickly is disclosed, including a base and nuts. A connecting shaft is fixedly installed in the middle of the upper end of the base, and a cross-shaped locking block is fixedly installed in the middle of the lower end of the base.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1-6 As shown, this utility model provides a technical solution: a diamond abrasive tool made of wear-resistant composite material, including a diamond grinding sleeve 1, a mounting base 2, and a mounting shaft 3. The inner side of the diamond grinding sleeve 1 has a slot 101, and a positioning block 11 is fixedly installed on the inner side of the diamond grinding sleeve 1. The surface of the mounting base 2 has a positioning groove 201, and the top of the mounting base 2 has an insertion hole 202. The mounting shaft 3 is slidably installed inside the insertion hole 202. A fixing plate 31 is fixedly installed on the surface of the mounting shaft 3, and a limit rod 32 is fixedly connected to the bottom of the fixing plate 31. The top of the mounting base 2 has a through hole 203 and two mounting holes 204. The interior of the mounting base 2 has a cavity 205. A rotating ring 4 is rotatably installed on the top of the mounting base 2, and a protrusion is fixedly installed on the top of the rotating ring 4. The bottom of the rotating ring 4 is fixedly connected to the push rod 42, and the bottom of the push rod 42 is fixedly connected to the connecting ring 43. The bottom of the mounting shaft 3 is rotatably mounted with the connecting sleeve 5. The movable block 6 is slidably mounted inside the cavity 205. The top of the movable block 6 is provided with a guide groove 601. The two sides of the movable block 6 are respectively fixedly connected with spring 61 and locking block 62. The positioning block 11 is T-shaped. The number of positioning blocks 11 is the same as the number of positioning grooves 201. The positioning blocks 11 are slidably mounted inside the positioning grooves 201. The push rod 42 slides through the inside of the mounting hole 204. The top of the connecting ring 43 is fitted to the bottom of the mounting base 2. One end of the surface of the push rod 42 is set inside the guide groove 601. The spring 61 is fixedly mounted inside the cavity 205. The locking block 62 slides outward to the inside of the locking groove 101.

[0026] In this embodiment, the positioning groove 201 on the surface of the mounting base 2 is aligned with the positioning block 11. The positioning block 11 is T-shaped. When the diamond grinding sleeve 1 is fitted and positioned on the surface of the mounting base 2, the height of the locking block 62 and the locking groove 101 can be aligned. The upper and lower ends of the push rod 42 are respectively connected and fixed to the rotating ring 4 and the connecting ring 43, so that the rotating ring 4 and the connecting ring 43 can abut against the upper and lower ends of the mounting base 2 respectively. The installed protrusion 41 facilitates the pushing of the rotating ring 4. One end of the push rod 42 is set in the guide groove 60. Inside the cavity 205, the shape of the guide groove 601 allows the push rod 42 to pull the movable block 6 to move when the rotating ring 4 is rotated. The movable block 6 and the locking block 62 move and retract into the cavity 205 at the same time. The spring 61 allows the movable block 6 and the locking block 62 to reset and move on their own when the rotating ring 4 is released. The locking block 62 can connect and fix the diamond grinding sleeve 1 to the mounting base 2 by moving and embedding it into the slot 101. The diamond grinding sleeve 1 can be installed and removed simply by pushing the rotating ring 4, which makes it convenient and quick to replace the diamond grinding sleeve 1.

[0027] Example 2

[0028] like Figures 1-6 As shown, the number of limiting rods 32 is the same as the number of through holes 203, and the limiting rods 32 are slidably installed inside the through holes 203. The bottom of the mounting shaft 3 is provided with a threaded inner hole 301. The mounting shaft 3 slides downward to the bottom of the mounting base 2. The top of the connecting sleeve 5 is provided with a groove 501. A screw 51 is fixedly installed inside the groove 501. The outer surface of the screw 51 is threadedly connected to the inner wall of the threaded inner hole 301.

[0029] In this embodiment, when the mounting shaft 3 is slidably inserted into the insertion hole 202, the limiting rod 32 is inserted into the through hole 203, so that when the mounting shaft 3 rotates, it can drive the mounting base 2 and the diamond grinding sleeve 1 to rotate together for grinding. The screw 51 is threadedly connected to the threaded inner hole 301 at the bottom of the mounting shaft 3. When the screw 51 and the threaded inner hole 301 are aligned and the connecting sleeve 5 is rotated, the connecting sleeve 5 can be fixed at the bottom of the mounting shaft 3. The fixing plate 31 and the connecting sleeve 5 clamp and limit the upper and lower ends of the mounting base 2 respectively. The groove 501 allows the connecting sleeve 5 to be sleeved on the bottom end of the mounting shaft 3, which can shorten the gap between the connecting sleeve 5 and the mounting base 2, increase the clamping force, thereby ensuring the stability of the diamond grinding sleeve 1 during use, and facilitating the installation and disassembly of the mounting base 2, so as to quickly replace the diamond grinding sleeve 1.

[0030] Working principle: When it is necessary to disassemble the diamond grinding sleeve 1 from the mounting base 2, the rotating ring 4 and push rod 42 are rotated by rotating the protruding block 41. Due to the shape of the guide groove 601, when the rotating ring 4 is rotated, the push rod 42 can pull the movable block 6 to move. The movable block 6 and the locking block 62 move and retract into the cavity 205 at the same time. At this time, the locking block 62 moves out from the slot 101. The diamond grinding sleeve 1 can be lifted upward to remove it from the surface of the mounting base 2, ensuring that the rotating ring 4 is pushed and fixed. Then, the new diamond grinding sleeve 1 is put on the surface of the mounting base 2 from top to bottom. The positioning block 11 is connected to the positioning groove 201. Then, the rotating ring 4 is released, and the spring 61 rebounds to make the movable block 6 and the locking block 62 move back to their original positions. When the locking block 62 moves outward and embeds into the slot 101, the diamond grinding sleeve 1 can be fixed on the surface of the mounting base 2. When the diamond grinding sleeve 1 is used, the mounting shaft 3 is connected and fixed to the motor output end. When the mounting shaft 3 is slidably inserted into the insertion hole 202, the limiting rod 32 is inserted into the through hole 203. Then, when the screw 51 on the connecting sleeve 5 is aligned with the threaded inner hole 301 and the connecting sleeve 5 is rotated, the connecting sleeve 5 can be fixed at the bottom of the mounting shaft 3. The fixing plate 31 and the connecting sleeve 5 respectively clamp and limit the upper and lower ends of the mounting base 2. The limiting rod 32 can make the mounting shaft 3 drive the mounting base 2 to rotate, thereby facilitating the quick installation and removal of the mounting base 2.
