DETAILED DESCRIPTION

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes a polishing shaft 1 and a polishing disc 2; the polishing shaft 1 is connected to the motor in the polishing machine; a connecting hole 3 is provided through the polishing disc 2, a groove 4 is provided through the connecting hole 3, and the polishing shaft 1 is movably inserted into the connecting hole 3;

[0027] It also includes:

[0028] The limiting ring 5 is fixedly sleeved on the polishing shaft 1, and several limiting blocks 6 are fixedly provided at equal angles on the limiting ring 5. The limiting blocks 6 are movably inserted into the groove on the bottom surface of the polishing disk 2. The limiting ring 5 and the limiting blocks 6 play a limiting role, which makes it easy to temporarily restrict the polishing disk 2 to a suitable position.

[0029] Positioning rod 7, there are several positioning rods 7, which are movably inserted into the polishing shaft 1 at equal angles, and the positioning rods 7 are engaged with the inner wall of the groove 4 to fix the polishing disc 2 on the polishing shaft 1. A fixing frame 20 is fixedly installed inside the polishing shaft 1, and the end of the crossbar of the fixing frame 20 is movably inserted into the positioning rod 7. The crossbar of the fixing frame 20 restricts the movement direction of the positioning rod 7.

[0030] The rotating sleeve 8 is screwed onto the polishing shaft 1 using a bearing, and is located below the limiting ring 5. A slot 9 is provided through the ring wall of the rotating sleeve 8. After the bolt passes through the side wall of the rotating sleeve 8, it is threaded onto the rod wall of the polishing shaft 1. The rotating sleeve 8 plays an adjustment role. The rotating sleeve 8 is fixed onto the polishing shaft 1 by the bolt. A rotating groove 21 is provided on the outer wall of the rotating sleeve 8. A rotating pad 22 is provided on the outer wall of the rotating sleeve 8. The rotating groove 21 and the rotating pad 22 are used to increase the friction on the outer wall of the rotating sleeve 8, which facilitates the rotation of the rotating sleeve 8.

[0031] The movable rod 10 is movably disposed inside the polishing shaft 1. One end of several adjusting rods 11 is screwed to the top of the movable rod 10 using a hinge seat, and the other end of the adjusting rod 11 is screwed to the positioning rod 7 using a hinge seat. The bottom end of the movable rod 10 is provided with a connecting buckle 12, which is slidably disposed on the rod wall of the polishing shaft 1 and in the slot 9. The connecting buckle 12 drives the movable rod 10 to move up and down, thereby causing the movable rod 10 to drive the adjusting rod 11 to rotate and adjust the position of the positioning rod 7.

[0032] The top end of the polishing shaft 1 is provided with a sealing component 13, which includes:

[0033] Connecting rod 14, there are several connecting rods 14, one end of each connecting rod 14 is screwed into the top groove of the polishing shaft 1 by a spring-loaded pivot, and the other end of the connecting rod 14 is provided with a sealing rod 15. The sealing rod 15 is set to abut against the inner wall of the groove 4. By rotating the connecting rod 14, the sealing plate is movably locked between the polishing shaft 1 and the inner wall of the groove 4, thereby protecting the positioning rod 7 in the groove 4. The side walls of the several sealing rods 15 are provided with protective pads 18, and the protective pads 18 are set to abut against the inner wall of the groove 4 to improve the sealing between the sealing rod 15 and the inner wall of the groove 4.

[0034] Connecting rope 16, there are several connecting ropes 16, one end of each connecting rope 16 is connected to the connecting rod 14, and the other end of the connecting rope 16 passes through the side wall of the polishing shaft 1 and is connected to the positioning rod 7. The positioning rod 7, in conjunction with the connecting rope 16, drives the connecting rod 14 to rotate. Several protrusions 19 are provided in the top groove of the polishing shaft 1, and the protrusions 19 are arranged to abut against the connecting rope 16. The end of the protrusion 19 is hemispherical to prevent the connecting rope 16 from being worn.

[0035] The sealing block 17 consists of several blocks, which are fixedly arranged at equal angles on the inner wall of the groove 4. The sealing rod 15 is engaged with the sealing block 17. Through the cooperation of the sealing block 17 and the sealing rod 15, the polishing shaft 1 is sealed with the inner wall of the groove 4, which protects the positioning rod 7 to a certain extent.

[0036] When using this utility model, if the polishing disc 2 needs to be installed on the polishing shaft 1, first insert the polishing shaft 1 into the connecting hole 3 until the limiting block 6 is movably inserted into the groove on the bottom surface of the polishing disc 2, so that the top end of the polishing shaft 1 is located in the groove 4. Then rotate the rotating sleeve 8. The rotating sleeve 8 uses the slot 9 to drive the connecting buckle 12 to move upward. The connecting buckle 12 drives the movable rod 10 to move. The movable rod 10 drives the adjusting rod 11 to rotate. The adjusting rod 11 drives the positioning rod 7 to move along the direction of the horizontal bar of the fixing frame 20 until the positioning rod 7 movably abuts against the inner wall of the groove 4. The positioning rod 7 moves. Simultaneously, the connecting rope 16 moves, the connecting rope 16 drives the connecting rod 14 to rotate, and the connecting rod 14 drives the sealing rod 15 to rotate until the sealing rod 15 is movably locked in the groove 4. Together with the sealing block 17, the gap between the polishing shaft 1 and the groove 4 is sealed, thereby protecting the positioning rod 7. Finally, the rotating sleeve 8 is fixed to the polishing shaft 1 with bolts. When removing the polishing disc 2, first unscrew the bolts, then reverse the rotating sleeve 8 so that the positioning rod 7 retracts into the polishing shaft 1. The connecting rod 14 drives the sealing rod 15 to rotate to the top of the polishing shaft 1, and then the polishing disc 2 is removed from the polishing shaft 1.

[0037] Compared with the prior art, the beneficial effects of this utility model are:

[0038] The rotating sleeve 8, in conjunction with the connecting buckle 12, drives the movable rod 10 to move, and adjusts the rotation of the adjusting rod 11, thereby controlling the movement of the positioning rod 7. The contact state between the positioning rod 7 and the inner wall of the groove 4 controls the connection between the polishing disc 2 and the polishing shaft 1, making it easier to assemble and disassemble the polishing head on the polishing machine.

[0039] The enclosure component 13 is set up, and the connecting rope 16 is used to make the positioning rod 7 rotate through the connecting rope 16 when it moves, thereby adjusting the enclosure rod 15 to a suitable position, thereby blocking the gap between the polishing shaft 1 and the inner wall of the groove 4, and protecting the positioning rod 7 to a certain extent.

[0040] The protective pad 18 is set to improve the sealing between the sealing rod 15 and the inner wall of the groove 4, so as to prevent dust from entering the groove 4 and affecting the movement of the positioning rod 7;

[0041] A fixed frame 20 is set up to restrict the movement of the positioning rod 7, so that the positioning rod 7 can only move along the direction of the horizontal bar of the fixed frame 20.

[0042] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
