[0027] As shown in Figure 1 and Figure 2 , the present application provides a vibration grinding and polishing device, which comprises a soundproof box 2 provided with a box cover 1, a grinding and polishing box 3 with an open top is arranged in the soundproof box 2, the grinding and polishing box 3 is fixed in the soundproof box 2 by a plurality of vibration springs 4, specifically, four vibration springs 4 are arranged at the four corners of the bottom of the grinding and polishing box 3, one end of the vibration spring 4 is fixedly connected with the bottom of the grinding and polishing box 3, and the other end of the vibration spring 4 is fixedly connected with the inner bottom of the soundproof box 2, open the box cover 1, put the polishing medium (such as grinding stone) and the parts into the grinding and polishing box 3, the polishing medium and the parts should be less than two-thirds of the volume of the grinding and polishing box 3 to avoid overflowing when vibrating, start the vibration motor 5 and close the box cover 1, under the action of the vibration motor 5 and the vibration spring 4, the grinding and polishing box 3 will produce three-dimensional vibration, this vibration makes the parts and the polishing medium make complex motion in the grinding and polishing box 3, so that the polishing medium and the surface of the parts collide and rub with each other, for the protruding part of the surface of the parts, the polishing medium will remove it through repeated impact and grinding, so that the surface of the parts becomes smooth gradually, the bottom of the grinding and polishing box 3 is provided with a vibration motor 5, the inner wall of the soundproof box 2, the inner wall of the box cover 1 and the outer wall of the grinding and polishing box 3 are all provided with sound-absorbing cotton 6, compared with the prior art, the noise generated inside the device (such as the noise generated by the collision of the parts and the polishing medium, the noise generated by the operation of the vibration motor 5 and the grinding and polishing box 3) is difficult to directly diffuse outward, greatly reducing the noise pollution to the surrounding environment such as the workshop, creating a relatively quiet working atmosphere for the operators and the surrounding area, and protecting the hearing health of the operators.

[0028] As shown in Figure 2 , one side of the grinding and polishing box 3 is provided with a discharge pipe 7, the discharge pipe 7 is provided with a discharge valve 8, the soundproof box 2 is provided with a discharge hopper 9, the inlet of the discharge hopper 9 is located below the discharge port of the discharge pipe 7, the discharge port of the discharge hopper 9 extends to the outside of the soundproof box 2, and the discharge port of the discharge hopper 9 is provided with a soundproof sealing assembly 10, when the polishing operation is finished, only the discharge valve 8 and the soundproof sealing assembly 10 need to be opened, and the material can flow out smoothly along the discharge pipe 7, avoiding the tedious operation of manually taking out the material from the box, greatly improving the discharging efficiency and saving the labor and time cost.

[0029] As Figure 1 shown, the soundproof sealing assembly 10 comprises a soundproof board 101, a locking screw 102, a hand wheel 103 and a locking rod 104, the discharge port of the discharge hopper 9 is provided with a clamping groove 11, the locking rod 104 is placed in the clamping groove 11, the locking rod 104 is provided with a threaded hole, the locking screw 102 penetrates through the threaded hole and is threadedly connected with the locking rod 104, the hand wheel 103 is fixedly arranged at one end of the locking screw 102, the locking screw 102 away from the hand wheel 103 can abut against the soundproof board 101 at the discharge port of the discharge hopper 9 by rotating the hand wheel 103, when the device is running, the noise in the soundproof box 2 can be prevented from spreading to the workshop from the discharge port of the discharge hopper 9, when discharging, the hand wheel 103 is rotated to loosen the abutment of the locking screw 102 on the soundproof board 101, the soundproof board 101 is removed, and then the locking screw 102, the hand wheel 103 and the locking rod 104 are removed, so that the parts and polishing medium falling into the discharge hopper 9 can flow out of the discharge port of the discharge hopper 9.

[0030] As Figure 2 shown, the inner wall of the grinding and polishing box 3 is attached with a rubber layer 12, during the grinding and polishing process, the parts and polishing medium will move violently in the box and collide with each other, the rubber layer 12 has a buffering effect, when the parts contact the wall of the box, the rubber layer 12 can effectively prevent the surface of the parts from being scratched or dented, thereby ensuring the quality of the surface of the parts.

[0031] As Figure 1 and Figure 2 shown, the box cover 1 and the soundproof box 2 are locked by magnetic attraction, the magnetic attraction makes the opening and closing operation of the box cover 1 extremely simple and fast, when the box cover 1 needs to be opened, a small external force is only needed to overcome the magnetic force, and the box cover 1 can be easily lifted; when the box cover 1 needs to be closed, the box cover 1 is only needed to be close to the soundproof box 2, and the magnetic force will automatically attract and lock the box cover 1 in the appropriate position, specifically, the bottom of the box cover 1 and the top of the soundproof box 2 are both fixedly provided with a magnet, the mutual attraction of the two magnets connects the box cover 1 and the soundproof box 2.

[0032] As Figure 2 shown, one side of the box cover 1 is hinged to the soundproof box 2 through a hinge 13, the side of the box cover 1 away from the hinge 13 is provided with a handle 14, the hinge action of the hinge 13 forms a stable connection structure between the box cover 1 and the soundproof box 2. When the box cover 1 needs to be opened or closed, the box cover 1 can stably rotate along the axis determined by the hinge 13, avoiding unstable conditions such as shaking, deviation or collision of the box cover 1 with the soundproof box 2, and the handle 14 provides a convenient force application position for the operator.

[0033] As Figure 2As shown, the sound-absorbing cotton 6 and the inner wall of the soundproof box 2, the sound-absorbing cotton 6 and the inner wall of the box cover 1, and the sound-absorbing cotton 6 and the outer wall of the grinding and polishing box 3 are connected by a magic tape (not shown in the figure). The sound-absorbing cotton 6 is connected by the magic tape, so that the installation process of the sound-absorbing cotton 6 becomes simple and fast. Compared with the traditional glue sticking or complex mechanical fixing method, by the magic tape, only the sound-absorbing cotton 6 needs to be aligned and pressed lightly, so that the fixing can be realized. When the sound-absorbing cotton 6 needs to be replaced after long-term use, or needs to be disassembled due to some reasons (such as damage, cleaning, etc.), the advantage of the magic tape connection method is more obvious. Only the magic tape needs to be torn off lightly, so that the sound-absorbing cotton 6 can be taken off, without causing damage to the surface of the soundproof box 2, the box cover 1 or the grinding and polishing box 3. Specifically, the magic tape is divided into a hook surface and a fuzzy surface. The hook surface is fixed on the inner wall of the soundproof box 2, the inner wall of the box cover 1 and the outer wall of the grinding and polishing box 3 (which can be fixed by using glue or the like), and the fuzzy surface is pasted on the back of the sound-absorbing cotton. When the sound-absorbing cotton is installed, only the fuzzy surface needs to be pasted with the hook surface.

[0034] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
