[0023] As Figures 1-5 shown, a surface treatment device for an elastic element of a sound-insulating coupling proposed by the present invention includes a frame 1, a grinding unit 2, a swinging unit 3, a reset unit 4, and a clamping unit. The grinding unit 2 is rotatably arranged on the frame 1; the grinding unit 2 includes a driving roller 201 rotatably arranged on the mounting frame 103, two driven rollers 202 both slidably arranged on the mounting frame 103 and located on both sides of the opening respectively, a grinding belt 203 arranged on the driving roller 201 and the driven rollers 202, and a first motor 205 arranged on the mounting frame 103 and having an output end connected to the driving roller 201.

[0024] The grinding unit 2 further includes two guide rollers 204 both rotatably arranged on the mounting frame 103 and located on both sides of the driving roller 201; the wrap angle between the grinding belt 203 and the driving roller 201 can be changed through the guide rollers 204, so that the driven roller 202 can effectively transmit power regardless of its position, avoiding slipping and failure. The guide rollers 204 are slidably connected to the grinding belt 203. The swinging unit 3 is rotatably arranged on the frame 1, and its output end is connected to the grinding unit 2; the reset unit 4 is arranged on the frame 1, and its output end is connected to the swinging unit 3; the clamping unit is slidably arranged on the frame 1.

[0025] It includes a bottom plate 101, a support frame 102 disposed on the bottom plate 101, and a mounting frame 103 disposed on the support frame 102 and having an opening.

[0026] In this embodiment, the coupling elastic element to be polished is sleeved on the inner clamping assembly 5, and the inner wall of the coupling elastic element is supported by the inner clamping assembly 5, so that it is convenient to polish the outer surface of the coupling elastic element; the moving assembly 7 drives the rotating assembly 6 to move, and the rotating assembly 6 drives the inner clamping assembly 5 to move towards the polishing belt 203, so as to squeeze the polishing belt 203 and make the inner clamping assembly 5 drive the coupling elastic element to move into the opening. At this time, the swing unit 3 drives the driven roller 202 to close, so that the wrap angle between the polishing belt 203 and the coupling elastic element can be increased, and the polishing can be more intensive, improving the polishing effect. And the inclined assembly 8 drives the rotating assembly 6 to incline, and the rotating assembly 6 drives the inner clamping assembly 5 to incline, so as to polish the edge of the coupling elastic element and remove the burrs generated during production. Embodiment

[0027] As Figures 1-5 As shown, a surface treatment device for a sound-insulating coupling elastic element proposed by the present invention. Compared with the first embodiment, in this embodiment, a sliding groove 1031 is provided on the mounting frame 103; the swing unit 3 includes two rotating arms 301 with one end rotatably disposed on the mounting frame 103 and the other end rotatably connected to the driven roller 202, two connecting rods 302 with one end rotatably disposed on the rotating arm 301, and a sliding rod 303 slidably disposed on the rotating arm 301; the rotating part of the driven roller 202 is located at the sliding groove 1031; the reset unit 4 includes a connecting rod 401 slidably disposed on the mounting frame 103 and connected to the sliding rod 303, a guide rail 402 disposed on the mounting frame 103 and slidably connected to the connecting rod 401, and an elastic member 403 disposed on the guide rail 402 and abutting against the connecting rod 401.

[0028] In this embodiment, the elastic member 403 pushes the connecting rod 401 to move, the connecting rod 401 drives the sliding rod 303 to move, the sliding rod 303 drives the connecting rod 302 to move, the connecting rod 302 drives the rotating arm 301 to incline, so as to drive the rotating arm 301 to open towards both sides, so as to drive the driven roller 202 and make the polishing belt 203 in a tensioned state.

[0029] When grinding, the grinding belt 203 is squeezed and deformed. At this time, the rotating arm 301 rotates, driving the driven roller 202 to close and reducing the distance between the two driven rollers 202. This can increase the contact area between the grinding belt 203 and the elastic element, facilitating the grinding process more conveniently. Moreover, it can ensure that the grinding belt 203 is in a taut state. And because the part of the grinding belt 203 in contact with the elastic element is lifted, the grinding belt 203 will undergo a convergent deformation, enabling it to adhere to the upper and lower edges of the elastic element, thus improving the grinding effect.

Compared with Embodiment 1 or Embodiment 2, in this embodiment, the clamping unit includes a rotating assembly 6 slidably arranged on the bottom plate 101, an inner clamping assembly 5 arranged at the output end of the rotating assembly 6, and a moving assembly 7 arranged on the bottom plate 101 for driving the rotating assembly 6 to move.

[0033] A guiding groove 6041 is arranged on the sliding frame 604; the inclination assembly 8 includes two sliding columns 801 arranged on the rotating frame 601 and slidably arranged in the guiding groove 6041, two sliding blocks 802 arranged on the sliding frame 604 and slidably connected to the sliding columns 801, a connecting frame 803 slidably arranged on the sliding frame 604 and connected to the two sliding blocks 802, and a telescopic cylinder 804 arranged on the sliding frame 604 with its output end connected to the sliding block 802.

[0034] In this embodiment, an elastic element is sleeved on the inner clamping assembly 5. By filling the inner clamping assembly 5 with gas, the airbag inside the inner clamping assembly 5 expands, driving the movement of the outer shell of the inner clamping assembly 5, so that it can abut against the inner wall of the elastic element, thereby clamping and fixing the elastic element, and facilitating the grinding treatment of the outer wall of the elastic element.

[0035] The telescopic cylinder 804 moves through the sliding block 802. The sliding block 802 drives the sliding column 801 to move. The sliding column 801 drives the rotating frame 601 to tilt, so that the rotating frame 601 drives the rotating shaft 603 to tilt. The rotating shaft 603 drives the inner clamping assembly 5 to tilt, so that the inner clamping assembly 5 drives the elastic element to tilt. When the side facing the grinding unit 2 is in the upward view angle, that is, the inner clamping assembly 5 tilts away from the grinding unit 2, the lower edge of the elastic element can be ground to remove the edge burrs. When the side facing the grinding unit 2 is in the downward view angle, the upper edge of the elastic element can be ground.
