The rotating assembly 30 is disposed on the base plate 10, and the rotating assembly 30 includes a rotating motor 31, a transmission gear set 32, and a rotating disk 33. The rotating motor 31 is in transmission connection with the transmission gear set 32, the rotating disc 33 is meshed with the transmission gear set 32, and the box body 20 is arranged on the rotating disc 33 and is coaxially arranged with the rotating disc 33.

The balance assembly 50 includes a mounting body 52 disposed around the box body 20, a first magnetic attraction member 54 disposed on the mounting body 52, and a second magnetic attraction member 56 disposed on the box body 20, wherein the first magnetic attraction member 54 and the second magnetic attraction member 56 are mutually repulsive and are corresponding in position.

During grinding, the vibration assembly 40 vibrates the housing 20, thereby causing a certain displacement between the abrasives in the housing 20. Meanwhile, the rotating motor 31 rotates, and the rotation is transmitted to the rotating disk 33 through the transmission gear set 32, so that the box body 20 rotates, on one hand, the collision speed between the grinding materials and the workpiece is increased, on the other hand, the effect of stirring the grinding materials is also achieved, and therefore the grinding quality is good, and the grinding efficiency is high. The first magnetic attraction piece 54 on the mounting body 52 and the second magnetic attraction piece 56 on the box body 20 repel each other, so that the box body 20 can be prevented from tilting due to rotation when vibrating, the box body 20 can vibrate in a large amplitude, and the grinding effect is further improved.

When the box 20 is vibrated, the box 20 is in an unbalanced state, that is, the bottom surface is high in some points and low in some points, and if the box 20 is rotated again, the box 20 may be inclined due to a centrifugal force caused by the rotation, thereby affecting grinding of the product. The mounting body 52 is fixed on the base plate 10 through a support pipe, and the first magnetic attraction piece 54 on the mounting body 52 is equivalent to pushing force on the box body 20, so that the box body 20 to be inclined is restored to balance, and the product can be well ground.

In this embodiment, the first magnetic member 54 is disposed around the inner wall of the mounting body 52, and the second magnetic member 56 is disposed around the outer wall of the box 20. Specifically, the first magnetic member 54 and the second magnetic member 56 can be continuously and integrally disposed around each other, or can be separated into several sections. In another embodiment, the width of the first magnetic attraction element 54 is greater than or equal to the width of the second magnetic attraction element 56, so that the second magnetic attraction element 56 can be always within the force-bearing range of the first magnetic attraction element 54. The first magnetic attraction piece 54 and the second magnetic attraction piece 56 can be realized by magnets, and the opposite surfaces of the first magnetic attraction piece 54 and the second magnetic attraction piece 56 are different magnetic poles, so that repulsion force is generated.

The second magnetic parts 56 are at least two groups, two groups of the second magnetic parts 56 are respectively arranged at the bottom and the top of the box body 20, at least two groups of the first magnetic parts 54 are arranged, and two groups of the first magnetic parts 54 are respectively arranged at the bottom and the top of the installation body 52. At least two sets of the first magnetic attraction pieces 54 and the second magnetic attraction pieces 56 respectively generate repulsion forces on the top and the bottom of the box body 20, so that the box body 20 can be kept well balanced.

During grinding, the vibration assembly 40 vibrates the housing 20, thereby causing a certain displacement between the abrasives in the housing 20. At the same time, the rotary motor 31 rotates, and the rotation is transmitted to the rotary disk 33 through the transmission gear set 32, so that the housing 20 rotates.

The rotary disk 33 includes a rotary gear 331 and a disk body 332 fixed to the rotary gear 331. Wherein, the rotary gear 331 is provided with a plurality of lightening holes to reduce the weight of the rotary gear.

A plane bearing 34 is arranged between the rotating disc 33 and the bottom plate 10, so that the rotating disc 33 and the bottom plate 10 can be rotatably connected. The rotary disc 33 is provided on the upper ring of the flat bearing 34 and the lower ring of the flat bearing 34 is provided on the base plate 10.

The rotating assembly 30 further includes a rotating cylinder shaft 35 rotatably disposed on the base plate 10. The rotating disc 33 is fixed at the upper end of the rotating cylinder shaft 35, and the radial movement of the rotating disc 33 is limited by the rotating cylinder shaft 35, so that the rotating disc 33 is prevented from retreating to be separated from the transmission gear set 32 in work. Wherein, the rotary disk 33, the plane bearing 34 and the rotary cylinder shaft 35 are coaxially arranged.

The rotating cylinder shaft 35 comprises a shaft disc 351 and a shaft rod 352, the shaft disc 351 is fixedly connected with the rotating disc 33, the upper end of the shaft rod 352 is connected with the shaft disc 351, and the lower end of the shaft rod 352 is rotatably arranged in a shaft hole formed in the bottom plate 10 in a penetrating mode.

The vibration motor 41 includes a motor body and eccentric blocks disposed at both ends of the motor body, and drives the box body 20 to vibrate by unbalance generated when the eccentric blocks rotate. During vibration, the spring assembly 42 of the support box 20 absorbs vibration energy through extension and contraction, so that the vibration is prevented from being transmitted to the vibration seat 43, and the working stability of the rotating assembly 30 is further influenced.

The vibration seat 43 is hollow and cylindrical, the spring group 42 comprises a plurality of springs which are annularly arranged on the vibration seat 43 at intervals, the upper end of the vibration motor 41 is fixed in the box body 20, and the lower end of the vibration motor extends into the vibration seat 43, so that the structure is more compact.
