[0023] Example 1

[0024] like Figures 1-4 As shown in the figure, the polishing device for automotive decorative accessories proposed in this embodiment includes a mounting bracket 1, a rotating mechanism, a polishing mechanism, and multiple sets of clamping components.

[0025] The rotating mechanism includes a rotating shaft 3, a servo motor 4, and two turntables 2. The rotating shaft 3 is rotatably mounted on the mounting bracket 1, and the two turntables 2 are respectively located at both ends of the rotating shaft 3. The servo motor 4 is mounted on the mounting bracket 1 and its output shaft is connected to the rotating shaft 3. Furthermore, a PLC controller 5 is mounted on the bracket 1.

[0026] At least three sets of clamping assemblies are provided; multiple sets of clamping assemblies are installed in a ring array on the outer periphery of the rotating shaft 3. The clamping assemblies include a decorative strip mounting plate 6, a second fixed clamping plate 92, a movable clamping plate 93, and two first fixed clamping plates 91. The second fixed clamping plate 92 and the two first fixed clamping plates 91 are all fixedly connected to the decorative strip mounting plate 6. The movable clamping plate 93 is slidably disposed on the decorative strip mounting plate 6. A drive assembly for driving the movable clamping plate 93 to move is installed on the decorative strip mounting plate 6. The drive assembly includes a threaded rod 18, a threaded sleeve 19, and a knob 21. The decorative strip mounting plate 6 has a movable groove 601 for the movable clamping plate 93 to slide. The threaded sleeve 19 is rotatably mounted on the end of the decorative strip mounting plate 6. The threaded rod 18 is fixedly connected to the movable clamping plate 93 and threadedly connected to the threaded sleeve 19. The knob 21 is connected to the outer end of the threaded sleeve 19. Gears 20 are fixed on multiple threaded sleeves 19. An incomplete gear ring 22 is fixedly connected to the mounting bracket 1 on the side adjacent to the gear 20.

[0027] The polishing mechanism includes a lifting plate 7, a polishing roller 8, a first motor 10, and a roller frame 11. The lifting plate 7 is vertically slidably mounted on the upper end of the mounting bracket 1, the roller frame 11 is mounted on the bottom end of the lifting plate 7, the polishing roller 8 is rotatably mounted on the roller frame 11, and the first motor 10 is mounted on the roller frame 11 with its output shaft connected to the rotating shaft of the polishing roller 8.

[0028] The working principle of this technical solution is as follows:

[0029] Clamping stage: The operator places the long decorative strip to be polished on the decorative strip mounting plate 6. The two long sides of the decorative strip are limited by two first fixed clamping plates 91, and one end is abutted by a second fixed clamping plate 92 to form a preliminary positioning. The operator manually rotates the knob 21 to drive the threaded sleeve 19 to rotate. The threaded sleeve 19 drives the threaded rod 18 connected to it to move axially, thereby pushing the movable clamping plate 93 to slide along the movable groove 601 toward the decorative strip. The coordinated action of the movable clamping plate 93, the fixed clamping plate 91 and the second fixed clamping plate 92 completes the stable clamping of the decorative strip.

[0030] Polishing stage: Servo motor 4 starts, driving the rotating shaft 3 to rotate multiple sets of clamping components in the ring array. The decorative strip passes through the polishing area at a uniform speed with the turntable 2. It should be noted that the multi-station design has more than or equal to 3 sets of clamping components. When one workpiece is being polished, the other stations can load and unload materials simultaneously, improving efficiency.

[0031] Adaptive polishing: When the decorative strip rotates to the top, its edge chamfer first contacts the polishing roller 8. The polishing roller is controlled by gravity and the lifting plate 7 to be in the lowest position, accurately matching the chamfer contour. The first motor 10 drives the polishing roller to rotate at high speed to polish the contact surface. As the rotating shaft 3 continues to rotate, the polished surface of the decorative strip and the chamfers on both sides contact the polishing roller in turn. The vertical sliding of the lifting plate 7 keeps the polishing roller in contact with the side curved surface.

[0032] Automatic unloading stage: When the clamping assembly carrying the polished decorative strip rotates to the unloading station, gear 20 meshes with the incomplete gear ring 22. During rotation, gear 20 rotates, causing the threaded sleeve 19 to rotate in the opposite direction, which in turn drives the threaded rod 18 to retract and the movable clamping plate 93 to move. In this state, the limit on the decorative strip can be released. After the clamping state is released, the decorative strip automatically falls to the collection area or belt conveyor under the action of gravity, without manual intervention. The incomplete gear ring 22 is designed to only trigger the rotation of gear 20 at the unloading station, while maintaining a clamped state at other positions to ensure safety.

[0033] Example 2

[0034] like Figure 3As shown, this embodiment proposes a polishing device for automotive decorative parts. Compared with the first embodiment, in this embodiment, the roller frame 11 is slidably installed at the bottom end of the lifting plate 7. The lifting plate 7 is equipped with a power component for driving the roller frame 11 to reciprocate. The power component includes a second motor 12, a cam 13, a connecting slider 14, a guide rod 15, and a spring 16. The second motor 12 is installed on the lifting plate 7, the cam 13 is connected to the output shaft of the second motor 12, the connecting slider 14 is connected to the roller frame 11, the lifting plate 7 has a sliding hole for the connecting slider 14 to slide, two mounting blocks 17 are arranged side by side on the lifting plate 7, the guide rod 15 is connected between the two mounting blocks 17, the connecting slider 14 is slidably arranged on the guide rod 15, and the spring 16 is sleeved on the guide rod 15.

[0035] In this embodiment, the second motor 12 drives the cam 13 to rotate, which pushes the connecting slider 14 to move laterally back and forth along the guide rod 15. The roller frame 11 drives the polishing roller 8 to swing left and right, and the spring 16 provides the restoring force to ensure that the polishing roller evenly covers the surface of the decorative strip and avoids excessive wear in some areas. The reciprocating motion of the polishing roller achieves multi-angle coverage, eliminates polishing dead angles, and evenly improves the smoothness.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
