[0020] 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.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Reference Figure 1-4 An automatic deburring device for injection molded parts includes a support frame 1, a conveyor belt 2 fixedly connected to the top of the support frame 1, multiple mounting plates 3 fixedly connected to the support frame 1, mounting columns 8 fixedly connected to the top of each mounting plate 3, each mounting column 8 having a limiting groove, a servo motor 10 fixedly connected to the top of the mounting column 8, a lead screw mechanism connected to the servo motor 10, a web plate 7 connected to the lead screw mechanism via a connecting mechanism, a rotating mechanism connected to the mounting plates 3, and a grinding mechanism connected to the web plate 7 via the rotating mechanism.

[0023] The lead screw mechanism includes a movable block 12, which has a threaded opening. The inner wall of the threaded opening has an internal thread. The output end of the servo motor 10 is fixedly connected to a lead screw 9. The outer wall of the lead screw 9 has an external thread. The internal thread and the external thread are threadedly connected. The outer wall of the movable block 12 is slidably connected to the inner wall of the limiting groove.

[0024] The mounting column 8 has a limiting groove inside, which is used to guide and limit the rotation of the moving block 12. In this way, under the drive of the servo motor 10, the rotation of the lead screw 9 can make the moving block 12 move up and down along the limiting groove. This design can precisely control the position of the moving block 12, thereby driving other mechanisms connected to it to work together.

[0025] The connecting mechanism includes two connecting rods 13. The outer wall of the moving block 12 is fixedly connected to a symmetrically arranged first mounting block, and the outer wall of the web plate 7 is fixedly connected to a symmetrically arranged second mounting block. The two connecting rods 13 have a first mounting port and a second mounting port. The inner wall of the first mounting port is rotatably connected to the outer wall of the first mounting block, and the inner wall of the second mounting port is rotatably connected to the outer wall of the second mounting block. This design allows the vertical movement of the moving block 12 to be converted into the swing of the web plate 7, thereby adjusting the working angle of the grinding mechanism.

[0026] The rotating mechanism includes two symmetrically arranged fixed plates 4 fixedly connected to the top of the mounting plate 3. Oppositely arranged rotating pins 6 are fixedly connected to the outer walls of the two fixed plates 4. A handle plate 5 is rotatably connected to the outer wall of the rotating pin 6, and the handle plate 5 is fixedly connected to the web plate 7. This ensures that the grinding mechanism maintains the appropriate angle and position under different conditions, effectively contacting the surface of the burr to be repaired.

[0027] The grinding mechanism includes a grinding roller 19, with second flanges 17 fixedly connected to both ends. A drive motor 14 is fixedly connected to the outer wall of one of the handle plates 5, and a rotating shaft is fixedly connected to the output end of the drive motor 14, passing through the handle plate 5. A rotating shaft 15 is rotatably connected to the outer wall of the other handle plate 5. Both the rotating shaft 15 and the rotating shaft are fixedly connected to the ends of a first flange 16. The first flange 16 and the second flange 17 are connected by multiple bolts 18, facilitating the replacement of the grinding roller 19. This enables quick installation and disassembly of the grinding roller 19.

[0028] The grinding roller 19 is located at the opening formed at the ends of the two handle plates 5.

[0029] The specific working principle of this utility model is as follows:

[0030] In the initial state, the injection molded part to be deburred is first placed on the conveyor belt 2. The conveyor belt 2, fixed on the support frame 1, will transport the injection molded part to the deburring station along a predetermined track. Multiple mounting plates 3 on the support frame 1 provide a stable support structure. After the servo motor 10 is started, it will drive the lead screw 9 to rotate. Since the lead screw 9 matches the internal thread in the moving block 12, the moving block 12 will move up and down along the limiting groove on the mounting column 8 under the drive of the lead screw 9. As the moving block 12 rises or falls, the first mounting block fixedly connected to it will also move accordingly. The connecting rod 13 in the connecting mechanism will move through its internal first... The mounting port and the second mounting port are respectively connected to the moving block 12 and the web plate 7, so that the movement of the moving block 12 can be smoothly transmitted to the web plate 7, causing the web plate 7 to complete the vertical displacement, thereby adjusting the grinding position. On the other hand, the rotating mechanism consists of two symmetrically arranged fixed plates 4 fixed on the top of the mounting plate 3 and a rotating pin 6 on the outside of the fixed plates 4. The handle plate 5 is sleeved on the outside of the rotating pin 6 and can rotate freely. The handle plate 5 and the web plate 7 are fixedly connected. This ensures that the grinding assembly can change the angle as needed to adapt to the edges of injection molded parts with different positions and shapes, ensuring the consistency and reliability of the grinding effect.

[0031] The drive motor 14 in the grinding mechanism is fixed on one of the handle plates 5 and drives the rotating shaft 15 and the connected first flange 16 to rotate rapidly. The grinding roller 19 is driven to rotate at high speed through the bolt 18 between the first flange 16 and the second flange 17. The grinding roller 19 is located in the gap between the ends of the two handle plates 5 and can directly contact the burr part of the injection molded part. Under the combined action of high speed rotation and proper position, the burrs are removed efficiently and accurately.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
