Description

Technical Field

[0001] This utility model relates to the field of plastic parts processing technology, specifically to a plastic surface treatment device. Background Technology

[0002] Plastics are materials that exhibit plastic behavior. Plasticity means that when subjected to external force, they deform and retain their original state after the force is removed. The elastic modulus of plastics is between that of rubber and fiber. They can undergo a certain degree of deformation under stress. Soft plastics are similar to rubber, while hard plastics are similar to fiber.

[0003] Currently, when processing plastic sheets, it is necessary to remove burrs from their surface. Existing plastic deburring devices usually cannot fix the plastic sheets in place, which causes the plastic sheets to easily shift during deburring, reducing the efficiency of deburring.

Figures 1 to 3 The plastic surface treatment equipment in this embodiment includes a processing box 1, a clamping mechanism inside the processing box 1, an electric push rod 2 fixedly mounted on the top of the processing box 1, a mounting frame 20 fixedly mounted on the output end of the electric push rod 2, a drive motor fixedly mounted inside the mounting frame 20, and a grinding disc 21 mounted on the output end of the drive motor.

[0014] In the above scheme, the clamping mechanism includes a frame 4 fixed in the processing box 1. A horizontal plate 40 is provided in the middle of the frame 4, and a fixed plate 42 is provided on one side of the horizontal plate 40. A drive assembly is provided on the horizontal plate 40 and the fixed plate 42. Two sets of symmetrical clamping plates 5 are provided above the horizontal plate 40 and the fixed plate 42. A guide rod 50 is provided on one side of the clamping plate 5. A mounting base 41 is provided on one side of the frame 4. The guide rod 50 is slidably connected to the mounting base 41. A first connecting arm 6 is rotatably connected to the mounting base 41. A second connecting arm 60 is hinged to one end of the first connecting arm 6. A third connecting arm 61 is hinged to one end of the second connecting arm 60. The second connecting arm 60 is hinged to the clamping plate 5. A connecting frame 7 is hinged to the middle of the second connecting arm 60.

[0015] In the above scheme, the drive component includes a slide rail 9 set at the bottom of the horizontal plate 40, two sets of slide plates 82 are symmetrically installed on the slide rail 9, and the top of the slide plate 82 is fixedly connected to the connecting frame 7; a drive arm 81 is hinged on the slide plate 82, and a connecting block 80 is hinged to one end of the drive arm 81; a cylinder group 8 is provided on the fixed plate 42, and the output end of the cylinder group 8 is fixedly connected to the connecting block 80.
