Description

Technical Field

[0001] This utility model relates to the field of tire processing technology, and in particular to an automatic deburring device for rubber tires. Background Technology

[0002] Tires are ring-shaped elastic rubber products fitted onto vehicles or machinery. Their main functions are to support the vehicle body, cushion impacts, ensure driving performance, and adapt to various mechanical requirements under complex road conditions.

[0003] After vulcanization or cutting, burrs or flash are easily generated on the inner edges, outer surfaces, and beads of rubber tires. These burrs not only affect the appearance quality of the tires but may also cause safety hazards during subsequent assembly or use, such as poor sealing and abnormal friction noise. Currently, tire deburring is mostly done manually with hand-held grinding tools, which results in uneven grinding force and range, and is prone to missed grinding or over-grinding, affecting the tire processing accuracy and lacking practicality. Therefore, it is necessary to redesign an automatic deburring device for rubber tires to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic deburring device for rubber tires.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic deburring device for rubber tires includes a base. A screw is rotatably mounted on the upper surface of the base via a movable frame. A stepper motor connected to the screw is fixedly mounted on the outer wall of the movable frame. A movable block is threadedly mounted on the outer wall of the screw via a limiting mechanism. A connecting plate is fixedly connected to the outer wall of the movable block via a connecting rod. A bearing is fixedly mounted on the outer wall of the connecting plate through an installation opening. A rotating shaft is fixedly mounted on the inner ring of the bearing. A servo motor connected to the rotating shaft is fixedly mounted on the outer wall of the connecting plate via a support mechanism. Multiple electric push rods are fixedly mounted on the end of the rotating shaft via a connecting block. Each extension end of the electric actuator is fixedly equipped with a support block. A support plate is fixedly installed on the upper surface of the base. The outer wall of the support plate has a movable opening. Two side movable plates are slidably installed inside the movable opening through a sliding mechanism. A side grinding plate is fixedly installed on the inner wall of each of the two side movable plates. A first servo hydraulic cylinder is fixedly installed on both outer walls of the support plate through a connecting mechanism. The extension ends of the two first servo hydraulic cylinders are respectively fixedly connected to the outer wall of the side movable plate on the same side. An upper movable plate is fixedly connected to the inner top wall of the support plate through a second servo hydraulic cylinder. An upper grinding plate is fixedly installed on the bottom wall of the upper movable plate.

[0007] Preferably, the limiting mechanism includes a limiting rod fixedly installed inside the movable frame, the limiting rod sliding through the movable block.

[0008] Preferably, the support mechanism includes a support frame fixedly installed on the outer wall of the connecting plate, and the servo motor is fixedly installed on the outer wall of the support frame.

[0009] Preferably, the connecting mechanism includes a connecting frame fixedly installed on the outer wall of the support plate, and the first servo hydraulic cylinder is fixedly installed on the inner wall of the connecting frame.

[0010] Preferably, two stabilizing rods are fixedly installed on the upper end face of the upper movable plate, and both stabilizing rods slide through the support plate.

[0011] Preferably, a controller is fixedly installed on the upper surface of the base, and the controller is electrically connected to the stepper motor, the servo motor, each electric push rod, the two first servo hydraulic cylinders and the second servo hydraulic cylinder.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up components such as the first servo hydraulic cylinder, the side moving plate, the second servo hydraulic cylinder and the upper moving plate, the positions of the side grinding plate and the upper grinding plate can be flexibly adjusted according to the tire size, so that they fit tightly against the tire surface. When the tire rotates, it can be ground evenly in all directions, avoiding the problems of missed grinding or over-grinding in manual grinding, improving the deburring accuracy and consistency, and ensuring the tire processing quality.

[0015] 2. By setting up components such as screws, limit rods, and moving blocks, a precise and stable transfer structure is formed. The screw is driven to rotate by a stepper motor, which drives the moving block to move axially. The limit rod restricts the rotation of the moving block, ensuring its smooth linear sliding. This allows the tire to accurately stop at the grinding station, ensuring alignment accuracy, meeting the transfer and adjustment needs of tires of different specifications, running smoothly, and ensuring consistent deburring.

Detailed Implementation

[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] Reference Figure 1-5 An automatic deburring device for rubber tires includes a base 1. A screw 3 is rotatably mounted on the upper surface of the base 1 via a movable frame 2. A stepper motor 4 connected to the screw 3 is fixedly mounted on the outer wall of the movable frame 2. A movable block 6 is rotatably mounted on the outer wall of the screw 3 via a limiting mechanism. A connecting plate 8 is fixedly connected to the outer wall of the movable block 6 via a connecting rod 7. A bearing 9 is fixedly mounted on the outer wall of the connecting plate 8 through an installation opening. A rotating shaft 10 is fixedly mounted on the inner ring of the bearing 9. A servo motor 12 connected to the rotating shaft 10 is fixedly mounted on the outer wall of the connecting plate 8 via a support mechanism. Multiple electric push rods 14 are fixedly mounted on the end of the rotating shaft 10 via a connecting block 13. Each electric push rod... Support blocks 15 are fixedly installed on the telescopic ends of the 14 bases. Support plates 16 are fixedly installed on the upper surface of the base 1. The outer wall of the support plate 16 has a movable opening. Two side movable plates 18 are slidably installed inside the movable opening through a sliding mechanism. Side grinding plates 19 are fixedly installed on the inner walls of the two side movable plates 18. First servo hydraulic cylinders 21 are fixedly installed on the outer walls of both sides of the support plate 16 through a connecting mechanism. The telescopic ends of the two first servo hydraulic cylinders 21 are fixedly connected to the outer walls of the side movable plates 18 on the same side. An upper movable plate 23 is fixedly connected to the inner top wall of the support plate 16 through a second servo hydraulic cylinder 22. An upper grinding plate 25 is fixedly installed on the bottom wall of the upper movable plate 23.

[0024] Furthermore, these support blocks 15 can be adjusted in position by extending and retracting the electric push rod 14 according to the inner diameter of the tire, thereby stably supporting tires of different sizes and ensuring that the tires do not shift during the deburring process.

[0025] The limiting mechanism includes a limiting rod 5 fixedly installed inside the movable frame 2, and the limiting rod 5 slides through the movable block 6.

[0026] Furthermore, the setting of the limit rod 5 can effectively restrict the movement trajectory of the moving block 6, prevent it from rotating with the screw 3 when the screw 3 rotates, and ensure that the moving block 6 can only move stably along a straight line.

[0027] The support mechanism includes a support frame 11 fixedly installed on the outer wall of the connecting plate 8, and a servo motor 12 fixedly installed on the outer wall of the support frame 11.

[0028] Furthermore, the support frame 11 provides a stable mounting base for the servo motor 12, which can reduce the impact of vibration generated by the servo motor 12 during operation on the rotation accuracy of the rotating shaft 10 and ensure the smoothness of the tire rotation process.

[0029] The connecting mechanism includes a connecting frame 20 fixedly installed on the outer wall of the support plate 16, and a first servo hydraulic cylinder 21 fixedly installed on the inner wall of the connecting frame 20.

[0030] Furthermore, the connecting frame 20 can firmly fix the first servo hydraulic cylinder 21 on the support plate 16 to prevent it from shifting its position when pushing the side moving plate 18, thus ensuring the stability of the grinding force of the side grinding plate 19.

[0031] Two stabilizing rods 24 are fixedly installed on the upper end face of the upper movable plate 23, and both stabilizing rods 24 slide through the support plate 16.

[0032] Furthermore, the stabilizer bar 24 can guide the upper moving plate 23 when it moves up and down, preventing the upper moving plate 23 from tilting due to uneven force, and ensuring that the contact position between the upper grinding plate 25 and the tire is accurate.

[0033] A controller 26 is fixedly installed on the upper surface of the base 1. The controller 26 is electrically connected to the stepper motor 4, the servo motor 12, each electric push rod 14, the two first servo hydraulic cylinders 21 and the second servo hydraulic cylinder 22.

[0034] Furthermore, the controller 26 enables precise setting and real-time control of the operating parameters of each component, such as adjusting the speed of the stepper motor 4 to control the tire's movement speed, making the deburring process more automated and intelligent.

[0035] A collection box 27 is slidably installed inside the base 1, and a collection opening that mates with the collection box 27 is provided on the upper surface of the base 1.

[0036] Furthermore, the location of the collection opening corresponds to the grinding area, allowing the burrs and debris generated during grinding to fall more smoothly into the collection box 27. The sliding installation design of the collection box 27 makes it convenient for staff to remove and clean it regularly, keeping the working environment of the device clean.

[0037] In use, the tire to be processed is placed on the outside of each support block 15. The controller 26 controls multiple electric push rods 14 to extend synchronously, causing each support block 15 to move outward synchronously and tighten the inner wall of the tire, thus fixing the tire. After the tire is fixed, the controller 26 starts the stepper motor 4, which drives the screw 3 to rotate inside the moving frame 2. Since the moving block 6 is threadedly connected to the screw 3 and the limiting rod 5 slides through the moving block 6, the moving block 6 moves smoothly along the length of the limiting rod 5 under the drive of the screw 3. Through the connecting rod 7, the connecting plate 8 moves synchronously, thereby moving the tire to the grinding area of ​​the support plate 16. When the tire reaches the preset grinding position... At this time, the controller 26 controls the stepper motor 4 to stop working. Subsequently, the controller 26 sends control signals to the first servo hydraulic cylinders 21 on both sides according to the width and outer diameter parameters of the tire to be processed. After receiving the signal, the first servo hydraulic cylinder 21 pushes the side moving plate 18 to slide along the moving opening of the support plate 16 until the side grinding plates 19 on both sides are tightly attached to the side walls of the tire. At the same time, the controller 26 controls the second servo hydraulic cylinder 22 to start. The extension end of the second servo hydraulic cylinder 22 drives the upper moving plate 23 to move downward. The upper moving plate 23 moves downward smoothly under the guidance of the stabilizer 24, so that the upper grinding plate 25 contacts the top surface of the tire.

[0038] After the grinding position is adjusted, the controller 26 starts the servo motor 12. The output shaft of the servo motor 12 drives the connecting block 13 and the tire supported by the support block 15 to rotate synchronously through the rotating shaft 10. During the rotation of the tire, the side grinding plate 19 and the upper grinding plate 25 continuously grind the burrs on the surface of the tire. The rubber debris generated by grinding falls into the collection box 27 through the collection opening on the upper end of the base 1, realizing the centralized collection of waste. When the tire is ground for a preset time, the controller 26 controls the servo motor 12, the first servo hydraulic cylinder 21 and the second servo hydraulic cylinder 22 to stop working in sequence. The side grinding plate 19 and the upper grinding plate 25 are reset under the drive of the first servo hydraulic cylinder 21 and the second servo hydraulic cylinder 22 respectively. Then, the controller 26 controls the stepper motor 4 to rotate in the opposite direction and move the ground tire to the initial loading position.

[0039] Finally, the controller 26 controls the electric push rod 14 to retract, and the support block 15 moves inward synchronously and separates from the inner wall of the tire. The operator can then remove the processed tire, completing a complete deburring operation. If continuous operation is required, the above operation process can be repeated. During the entire operation, the collection box 27 can be pulled out from the base 1 at any time to clean up the collected rubber debris, ensuring the continuous and stable operation of the device. The controller 26 can pre-store grinding parameters for various tire specifications. The operator only needs to select the appropriate parameter based on the actual tire model to achieve automated grinding, greatly improving the equipment's versatility and ease of operation.

[0040] 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.
