[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figure 1-4 A 3D-printed mirror surface treatment device for vehicle interior parts includes a base 1. Two push components are symmetrically fixed on one side of the upper end face of the base 1, and each push component is connected to a push plate 11. Each push plate 11 is provided with an adaptive clamp. A lifting bracket is fixed on the other side of the upper end face of the base 1. A bracket is installed on the lifting bracket. A reciprocating component is installed on the bracket. An angle adjustment frame is installed on the reciprocating component. A polishing component is installed on the angle adjustment frame.

[0024] The adaptive clamp includes T-shaped clamping rods 19 that are equidistantly inserted into the push plate 11. A retaining ring 17 is fixed on the outer wall of the middle part of each T-shaped clamping rod 19, and a spring 18 is sleeved on the part of each T-shaped clamping rod 19 located between the retaining ring 17 and the push plate 11.

[0025] The pushing assembly includes two first electric push rods 9 fixed to the side of the upper surface of the base 1. One end of the two first electric push rods 9 is connected to a U-shaped plate 10, and the pushing plate 11 is fixed to both sides of the U-shaped plate 10.

[0026] The lifting bracket includes a U-shaped rod 3 fixed to the upper surface of the base 1. Lifting blocks 2 are slidably sleeved on the vertical sections on both sides of the U-shaped rod 3. A second electric push rod 4 is installed between the upper end of the lifting block 2 and the lower end of the horizontal section of the U-shaped rod 3.

[0027] The bracket includes a U-shaped crossbeam 7 fixed to the bottom of one side of the lifting block 2, and a vertical pole 16 is fixed to one end of the upper surface of the U-shaped crossbeam 7.

[0028] The reciprocating assembly includes a threaded rod 5 rotatably mounted on a vertical pole 16 via bearings, a first servo motor 14 fixed on a lifting block 2, the output end of the first servo motor 14 connected to one end of the threaded rod 5, a movable plate 6 screwed onto the threaded rod 5, a mounting frame 15 fixed to the bottom of one side of the movable plate 6, and sliding sleeves 8 slidably sleeved on both sides of the U-shaped crossbeam 7. A connecting rod 12 is fixed to the opposite side of each of the two sliding sleeves 8, and the opposite ends of the two connecting rods 12 are respectively fixed to the opposite outer walls of the mounting frame 15.

[0029] The angle adjustment frame includes two rotating rods 22 that are rotatably mounted on the inner walls of opposite sides of the mounting frame 15 via bearings. Each of the opposite ends of the two rotating rods 22 is connected to a U-shaped base 20. A third electric push rod 21 is rotatably mounted between one side of the moving plate 6 and the upper end face of the U-shaped base 20.

[0030] The polishing assembly includes a second servo motor 23 fixed on a U-shaped base 20, the output end of which extends below the mounting frame 15 and is fitted with a polishing wheel 13.

[0031] The interior trim piece to be polished is placed on the base 1. The first electric push rods 9 on the two push plates 11 are used to move the two push plates 11, causing the T-shaped clamps 19 on the push plates 11 to contact the interior trim piece. The T-shaped clamps 19 contact different positions on the interior trim piece, and the springs 18 on each T-shaped clamp 19 are compressed to ensure that each T-shaped clamp 19 can adapt to the curved surface of the interior trim piece, thus clamping it. The first servo motor 14 drives the threaded rod 5 to rotate, causing the threaded rod 5 to drive the moving plate 6 to move the mounting frame 15 back and forth. The connecting rod 12 and the sliding sleeve 8 move on the U-shaped crossbeam 7 to maintain the stability of the moving mounting frame 15. The second servo motor 23 drives the polishing wheel 13 to rotate, and the extension and retraction of the second electric push rod 4 drives the lifting block 2 to move up and down, so that the polishing wheel 13 contacts the surface of the interior trim. As the polishing wheel 13 moves, the surface of the interior trim is polished. The extension and retraction of the third electric push rod 21 can be controlled to drive the U-shaped base 20 to rotate at a certain angle, so as to facilitate the adjustment of the tilt angle of the polishing wheel 13, so as to reduce the contact area between the polishing wheel 13 and the interior trim and prevent over-polishing.

[0032] Example 2 is an optimization based on Example 1, specifically:

[0033] Each T-shaped clamp 19 has a rubber pad at its end. The rubber pad prevents the T-shaped clamp 19 from scratching the interior trim parts when it comes into contact with them, thereby reducing the scrap rate.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
