[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0035] Referring to Figures 1 - 3 , an embodiment provided by the present utility model: a quick connection mechanism for an abrasive tool and a grinding machine, comprising: a grinding machine body 1, which serves as the drive of the entire device, and a sleeve 2 is fixedly connected to the output end of the grinding machine body 1. A chute 5 and a concave hole 6 are provided inside the sleeve 2; a grinding plate 3, which is used for grinding an object, and a mounting shaft 4 is fixedly connected to the side wall of the grinding plate 3; a quick installation mechanism, which is arranged inside the mounting shaft 4 and is used for quickly fixing the mounting shaft 4 and the sleeve 2. The quick installation mechanism includes a central shaft 7, the side wall of the central shaft 7 is fixedly connected inside the mounting shaft 4, a sliding plate 8 is slidably connected to the side wall of the central shaft 7, a spring 9 is sleeved on the side wall of the central shaft 7, one end of the spring 9 is fixedly connected inside the mounting shaft 4, and the other end of the spring 9 is fixedly connected to the side wall of the sliding plate 8; a positioning column 10 is fixedly connected to the side wall of the central shaft 7, a clamping block 11 is slidably connected to the side wall of the positioning column 10, the side wall of the clamping block 11 is slidably connected inside the mounting shaft 4, the side wall of the clamping block 11 is slidably connected inside the concave hole 6, a first articulated frame 12 is fixedly connected to the side wall of the clamping block 11, a second articulated frame 13 is fixedly connected to the side wall of the sliding plate 8, a connecting plate 14 is rotatably connected between the first articulated frame 12 and the second articulated frame 13, a slider 15 is fixedly connected to the side wall of the mounting shaft 4, the side wall of the slider 15 is slidably connected to the side wall of the chute 5, and the side wall of the mounting shaft 4 is slidably connected inside the sleeve 2.

[0036] When installing the grinding machine body 1 and the grinding plate 3, first insert the mounting shaft 4 connected to the grinding plate 3 into the inside of the sleeve 2, and make the slider 15 connected to the mounting shaft 4 slide into the chute 5 opened inside the sleeve 2, and move the grinding plate 3 towards the grinding machine body 1, so that the mounting shaft 4 slides into the inside of the sleeve 2. During this process, the inner wall of the sleeve 2 will exert pressure on the clamping block 11, causing it to slide along the positioning column 10 into the inside of the mounting shaft 4. During the sliding process of the clamping block 11, one side of the connecting plate 14 will rotate inside the hinge bracket one 12, and the other side will rotate inside the hinge bracket two 13. At the same time, the sliding plate 8 will be pushed to both sides, squeezing the spring 9 to deform it. As the mounting shaft 4 goes deeper into the sleeve 2, when the clamping block 11 moves to the concave hole 6 opened inside the sleeve 2, at this time, the clamping block 11 will lose the extrusion pressure from the sleeve 2, so that the spring 9 loses pressure and resets. At this time, the spring 9 will push the sliding plate 8 to move, and cause the connecting plate 14 to deflect between the hinge bracket one 12 and the hinge bracket two 13, thereby pushing the clamping block 11 outwards and making it snap into the inside of the concave hole 6, thus completing the connection between the mounting shaft 4 and the sleeve 2, and completing the preliminary installation process of the grinding plate 3.

[0037] Referring to Figure 4 , a locking mechanism for locking the installation position of the grinding plate 3; the locking mechanism includes a fixing ring 16, the side wall of the fixing ring 16 is fixedly connected to the side wall of the grinding machine body 1, a first clamping ring 17 is fixedly connected to the side wall of the fixing ring 16, a first claw 18 is fixedly connected to the side wall of the fixing ring 16, a rotating ring 19 is arranged on one side of the fixing ring 16, a second claw 20 is fixedly connected to the side wall of the rotating ring 19, a second clamping ring 21 is fixedly connected to the side wall of the rotating ring 19, the second claw 20 is engaged with the first clamping ring 17, the first claw 18 is engaged with the second clamping ring 21, an annular groove 22 is opened inside the rotating ring 19, a connecting ring 23 is fixedly connected to the side wall of the grinding plate 3, and the side wall of the connecting ring 23 is rotatably connected inside the annular groove 22, and the grinding plate 3 is connected to the rotating ring 19 through the connecting ring 23.

[0038] After the connection between the mounting shaft 4 and the sleeve 2 is completed, the swivel ring 19 will fit against the fixed ring 16. In this state, the second pawl 20 and the second snap ring 21 connected to the swivel ring 19 will be misaligned with the first snap ring 17 and the first pawl 18 connected to the fixed ring 16. At this time, by twisting the swivel ring 19, the second pawl 20 and the second snap ring 21 are driven to move. As the second pawl 20 moves, it will gradually engage with the first snap ring 17. At the same time, the first pawl 18 will also gradually engage with the second snap ring 21, thus completing the locking of the grinding plate 3, preventing the mounting shaft 4 from falling out of the inside of the sleeve 2 during use, ensuring the stability of the entire device. After the installation is completed, by starting the grinding machine body 1, the sleeve 2 can be driven to rotate. Since the sleeve 2 is connected to the grinding plate 3, the rotation of the sleeve 2 will be transmitted to the grinding plate 3, causing the grinding plate 3 to rotate accordingly, and thus performing the grinding work.

[0039] Working principle: When installing the grinding machine body 1 and the grinding plate 3, first slide the slider 15 connected to the mounting shaft 4 into the chute 5 opened inside the sleeve 2, and then push it inward to move the grinding plate 3 in the direction of the grinding machine body 1. During the movement, the inner wall of the sleeve 2 will squeeze the clamping block 11 and make it slide into the inside of the mounting shaft 4. During the sliding of the clamping block 11, one side of the connecting plate 14 will rotate inside the first hinge bracket 12, and the other side will rotate inside the second hinge bracket 13, and push the sliding plate 8 to both sides, squeezing the spring 9 to deform it. As the mounting shaft 4 penetrates deeper into the sleeve 2, when the clamping block 11 moves to the concave hole 6 opened inside the sleeve 2, at this time the clamping block 11 will lose the force of the sleeve 2 squeezing it, so that the spring 9 loses pressure and resets. At this time, the spring 9 will push the sliding plate 8 to move, and make the connecting plate 14 deflect between the first hinge bracket 12 and the second hinge bracket 13, thus pushing the clamping block 11 outward and making it snap into the inside of the concave hole 6. At this time, the connection between the mounting shaft 4 and the sleeve 2 is completed;

[0040] After the connection between the mounting shaft 4 and the sleeve 2 is completed, the swivel ring 19 will fit against the fixed ring 16, and the second pawl 20 and the second snap ring 21 connected to the swivel ring 19 will be misaligned with the first snap ring 17 and the first pawl 18 connected to the fixed ring 16. At this time, by twisting the swivel ring 19 to drive the second pawl 20 and the second snap ring 21 to move, the second pawl 20 will gradually engage with the first snap ring 17. At the same time, the first pawl 18 will also gradually engage with the second snap ring 21, thus completing the locking of the grinding plate 3. Then, by starting the grinding machine body 1 to drive the sleeve 2 to rotate, and further drive the grinding plate 3 to rotate to perform the grinding work on the object.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
