Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figure 1-4 As shown, this utility model provides an automatic burr removal device for the outer diameter of plastic products, comprising: a base 1, on which a reduction motor 2 is mounted, the reduction motor 2 being an integrated servo motor and a reducer, with its output shaft extending upward perpendicularly to the surface of the base 1; a contour positioning block 3 is mounted on the top of the reduction motor 2, the bottom of the contour positioning block 3 being connected to the output shaft of the reduction motor 2 and capable of rotating with it, the shape of the contour positioning block being adapted to the inner surface shape of the plastic product, used to position the plastic product and prevent the product from deviating significantly from the axis during rotation, and capable of rotating together with it under the drive of the reduction motor 2; a pressing mechanism is mounted above the contour positioning block 3. 4. The pressing mechanism 4 can press the plastic product firmly on top of the contour positioning block 3 after it is positioned, preventing the product from slipping during rotation and ensuring that the plastic product can rotate stably around the output shaft of the reduction motor 2 during deburring. A deburring mechanism is provided on one side of the contour positioning block 3, which includes a moving base 5. A knife holder cylinder 6 and a knife holder 7 are mounted at the front end of the moving base 5. A blade 8 is mounted at the front end of the knife holder 7. The blade 8 can adhere to the surface of the plastic product under the action of the knife holder cylinder 6, and clean the burrs on its outer diameter edge in conjunction with the rotation of the plastic product. After deburring is completed, the knife holder cylinder 6 drives the knife holder 7 to retract, and the reduction motor 2 stops rotating. Through the above structural coordination, the process of removing burrs from the outer diameter of the plastic product is automated, improving the product's appearance quality and reducing the labor intensity of operators.

[0033] The pressing mechanism 4 includes a rotary pressing cylinder 401, a rotating rod 402, and a pressing head 403. The bottom of the rotary pressing cylinder 401 is fixedly connected to the side or edge of the contour positioning block 3, and its top end is at least 10cm above the surface of the contour positioning block 3. One end of the rotating rod 402 is connected to the end of the push rod of the rotary pressing cylinder 401, and the pressing head 403 is connected to the other end of the rotating rod 402 and extends downward. By rotating the rotary pressing cylinder 401, the rotating rod 402 can be rotated to the top of the contour positioning block 3 or moved away from it, which facilitates the positioning of plastic products on the contour positioning block 3. After the plastic product is positioned, the pressing head 403 rotates to the top of it and moves downward under the drive of the rotary pressing cylinder 401 to press on the surface of the plastic product. The pressing head 403 is a flexible pressing head to avoid damaging the surface of the plastic product. There are two sets of pressing mechanisms 4, which can be used together to ensure that the plastic product is pressed tightly when cleaning burrs, and to avoid scratches on the product surface due to uneven rotation.

[0034] Furthermore, the surface of the base 1 is provided with two parallel dovetail grooves 9. The dovetail grooves 9 are set from the edge of the base toward the contour positioning block 3. The bottom of the movable seat 5 is provided with a slider 10 that is adapted to slide with the dovetail grooves 9. By the cooperation of the slider 10 and the dovetail grooves 9, the position of the movable seat 5 on the base 1 can be adjusted so that it is close to the contour positioning block 3. Both ends of the movable seat 5 are provided with an integral connecting block 11. The connecting block 11 is equipped with a tightening screw 12. By tightening the tightening screw 12, it can be made to cooperate with the base 1 and be tightened to fix the position of the movable seat 5.

[0035] In this embodiment, the blade holder 7 is mounted on the front end of two guide rods 13, and a spring 14 is sleeved on the front end of the guide rods 13. The rear ends of the two guide rods 13 pass horizontally through the movable seat 5. When the blade 8 is pressed against the outer periphery of the plastic product, the spring 14 is in a compressed state. The front end of the blade holder cylinder 6 is L-shaped and can be locked on the side of the blade holder 7 away from the spring 14. When the movable seat 5 moves close to the contour positioning block 3, by extending the blade holder cylinder 6, the blade holder 7 can be extended under the rebound action of the spring 14, so that the blade 8 is pressed against the outer diameter of the plastic product to be deburred. The spring 14 can ensure the cutting force of the blade 8, thereby removing the burr.

[0036] In this embodiment, an adjusting rod 15 is fitted onto the outer side of the guide rod 13. The outer periphery of the adjusting rod 15 is provided with an external thread that is threaded to the movable seat 5. A ball bearing is provided between the inner wall of the adjusting rod 15 and the outer periphery of the guide rod 13. By rotating the adjusting rod 15, one end can extend out from the front end of the movable seat 5, and the end of the spring 14 abuts against the end face of the adjusting rod 15. The adjusting rod 15 is screwed closer to the tool holder 7, thereby adjusting the compression of the spring 14 to achieve the effect of adjusting the cutting force of the blade 8. By providing the ball bearing, it is possible to prevent the guide rod 13 from shaking or generating large friction with the inner wall of the adjusting rod 15 when rotating the adjusting rod 15, thus affecting the position of the tool holder 7. The front end of the guide rod 13 is embedded in or threadedly connected to the tool holder 7, which facilitates the overall installation and disassembly of the tool holder 7. The position of the blade 8 on the tool holder 7 can be adjusted, which is convenient for fine-tuning the position of the blade 8 after the movable seat 5 is moved into place.

[0037] The base 1 is also equipped with a start / stop button 16, which can control the rotation of the pressing cylinder 401 to clamp the product and the start / stop of the geared motor 2, thereby performing automatic deburring operations. The side of the base 1 is equipped with an external signal port 17, which facilitates the connection of an external robotic arm for picking up and placing plastic products, realizing production line automation and improving production efficiency.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
