Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic product processing and polishing technology, and specifically discloses a polishing device with a flipping function for processing plastic products. Background Technology
[0002] After injection molding, plastic products often have defects such as burrs, parting lines, and ejector pin marks on their surface due to factors such as overflow at the mold parting surface and demolding stress. These defects directly affect the product's sealing performance, assembly accuracy, and appearance quality, requiring multiple surfaces of the product to be polished. At this time, a polishing device with a flipping function is needed.
[0003] Existing grinding devices with flipping function, although equipped with a rotating clamping mechanism, adopt a single-degree-of-freedom flipping structure, which can only achieve 180° planar flipping. This makes it difficult to adapt to the multi-faceted processing requirements of plastic parts, and the clamping force is not adjustable, which can easily lead to product deformation. Therefore, a grinding device with flipping function for processing plastic products is needed to solve this problem. Utility Model Content

By using two flipping mechanisms in alternating cooperation, different sides of the workpiece can be clamped and exchanged, which facilitates grinding of the non-clamped surfaces and achieves the purpose of grinding multiple surfaces. In addition, the clamping force can be adjusted by a pressure sensor to prevent the workpiece from deforming during the clamping process.

The output ends of both second electric push rods pass through the U-shaped frame and are fixedly connected to a rectangular plate. Pressure sensors are installed on the opposite sides of the two rectangular plates. An auxiliary plate is fixedly connected to the opposite sides of the two pressure sensors.

[0024] The flipping mechanism includes a fixed plate 2 fixedly connected to the base 1. A first electric push rod 3 is installed on the outer wall of the fixed plate 2. The output end of the first electric push rod 3 passes through the fixed plate 2 and is fixedly connected to a drive seat 4. A rectangular groove 5 is opened through the outer wall of the drive seat 4. A third motor 6 is installed inside the rectangular groove 5.

The two second electric push rods 8 are activated to simultaneously advance the rectangular plate 9. The clamping force is monitored in real time by the pressure sensor 10. When the pressure value reaches the preset threshold, the advancement stops. At this time, the auxiliary plate 11 is in contact with the surface of the workpiece. At this time, the upper surface of the workpiece can be ground. After the upper surface is ground, the third motor 6 is activated to drive the U-shaped frame 7 and the workpiece to flip and grind the other side of the workpiece.
[0027] The left-side flipping mechanism is activated, and the first electric push rod 3 is started to push the drive seat 4 to move along the slide, so that the U-shaped frame 7 moves directly below the grinding mechanism.

The two second electric push rods 8 are started to advance the rectangular plate 9 synchronously. The clamping force is monitored in real time by the pressure sensor 10. When the pressure value reaches the preset threshold, the advancement stops. At this time, the upper and lower end faces of the workpiece are clamped by the two clamping plates 17. Then, the front flipping mechanism is reset, so that the two clamping plates 17 are away from the workpiece. Then, the third motor 6 located on the left-side flipping mechanism is started to drive the U-shaped frame 7 and the workpiece to flip 90 degrees. Then, the first motor 12 is started to drive the clamping plates 17 and the workpiece clamped by the two clamping plates 17 to rotate, so that the grinding surface of the workpiece faces upward, so that multiple surfaces of the workpiece can be ground continuously.
[0028] As a technical optimization of this utility model, the grinding mechanism includes a bracket 13 fixedly connected to the upper end of the base 1. A third electric push rod 14 is installed at the upper end of the bracket 13. The output end of the third electric push rod 14 passes through the bracket 13 and is fixedly connected to a frame 15.

[0033] In this embodiment, one U-shaped frame 7 is set vertically and the other U-shaped frame 7 is placed horizontally, which can facilitate clamping different surfaces of the workpiece.
[0034] As a technical optimization of this utility model, the outer walls of both auxiliary plates 11 abut against the inner wall of the U-shaped frame 7.
[0035] In this embodiment, the outer walls of both auxiliary plates 11 abut against the inner wall of the U-shaped frame 7, which can increase the stability of the movement of the auxiliary plates 11.
[0036] As a technical optimization of this utility model, a controller is installed on the outer wall of the bracket 13.
[0037] In this embodiment, the controller is electrically connected to the first motor 12, the second motor 16, the third motor 6, the first electric actuator 3, the second electric actuator 8, the third electric actuator 14, and multiple pressure sensors 10, and the controller can control the operation of each component.
[0038] The working principle and usage process of this utility model are as follows: When in use, the flipping mechanism located at the front works first: the controller starts the first electric push rod 3 to push the drive seat 4 to move along the slide groove, so that the U-shaped frame 7 moves to the bottom of the grinding mechanism, and the workpiece is placed between the two auxiliary plates 11. The two second electric push rods 8 are started to push the rectangular plate 9 synchronously. The clamping force is monitored in real time by the pressure sensor 10. When the pressure value reaches the preset threshold, the pushing stops. At this time, the auxiliary plate 11 is in contact with the surface of the workpiece. At this time, the upper surface of the workpiece can be ground. After the upper surface is ground, the third motor 6 is started to drive the U-shaped frame 7 and the workpiece to flip and grind the other side of the workpiece.
[0039] Next, the left-side flipping mechanism is activated, and the first electric push rod 3 is started to push the drive seat 4 to move along the slide, so that the U-shaped frame 7 moves directly below the grinding mechanism. At this time, the two clamping plates 17 are located at the upper and lower ends of the workpiece respectively. The two second electric push rods 8 are started to synchronously advance the rectangular plate 9. The clamping force is monitored in real time by the pressure sensor 10.

Then, the first motor 12 is started to drive the clamping plates 17 and the workpiece clamped by the two clamping plates 17 to rotate, so that the grinding surface of the workpiece faces upward, so that multiple surfaces of the workpiece can be ground continuously.
