Description

Technical Field

[0001] This utility model relates to a tire gripper specifically for tire vulcanizing machines, used for loading and unloading tires onto and off the tire vulcanizing machine. Background Technology

[0002] A tire vulcanizing machine is a specialized piece of equipment used for vulcanizing tires. It is mainly used in the production of passenger car and light and medium-duty truck tires. Through a hydraulic system and high temperature and pressure, the formed tire blank is vulcanized and shaped, achieving a cross-linking reaction of the rubber molecular chains, thereby solidifying the rubber and giving it properties such as elasticity and wear resistance. Because the vulcanization process requires the use of high-temperature steam, tire grippers are typically used to load and unload the tire blanks.

[0003] Existing tire vulcanizing machine grippers typically include a tire-gripping robot arm mounted on a rotating arm. The gripper arm moves to the tire blank to be vulcanized, then grasps the tire blank and moves it to the vulcanizing position of the vulcanizing machine, placing the tire blank there. The gripper arm then moves to a waiting area. After the tire blank has been vulcanized and set, the gripper arm moves back to the vulcanizing position to remove the vulcanized tire blank. This completes one cycle of loading and unloading tire blanks into the vulcanizing machine. This cycle can be repeated repeatedly to load and unload tire blanks.

[0004] However, existing tire vulcanizing machine grippers typically only have one tire gripping robot, which cannot load the next tire blank at the same time as unloading the previous one. This results in a long loading and unloading time and low efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a tire gripper specifically for tire vulcanizing machines, in order to solve the problem that existing tire grippers for tire vulcanizing machines have only one tire gripping robot arm, resulting in low efficiency in loading and unloading tires.

[0006] To solve the above problems, the tire gripper for tire vulcanizing machines involved in this utility model adopts the following technical solution: A tire gripper for a tire vulcanizing machine includes a base with a left and right turntable rotatable relative to it. Both turntables rotate around their central axes. The left turntable is driven by a left power mechanism, and the right turntable by a right power mechanism. Support columns are fixedly mounted on both turntables. Sliding arms are mounted on the support columns and guided vertically. A first power mechanism drives the sliding arms' vertical movement. Each sliding arm has an openable and closable mechanical gripper driven by a second power mechanism. The outer periphery of the base has a tire gripping station, a vulcanizing station, and a tire unloading station. At each workstation, the left turntable, with its mechanical gripper, reciprocates between the tire gripping station and the vulcanizing station. The right turntable, with its mechanical gripper, reciprocates between the vulcanizing station and the tire unloading station. The left power mechanism reciprocates within a specific angle. When the left power mechanism rotates to its two extreme angles, the left turntable, with its mechanical gripper, rotates to the tire gripping station and the vulcanizing station, respectively. The right power mechanism reciprocates within a specific angle. When the right power mechanism rotates to its two extreme angles, the right turntable, with its mechanical gripper, rotates to the vulcanizing station and the tire unloading station, respectively. The mechanical grippers on the left and right turntables are not simultaneously located at the vulcanizing station.

[0007] The mechanical gripper includes a fixed plate, and several claws are evenly distributed along the circumference below the fixed plate. The claws are slidably mounted on the fixed plate. When the claws are close to each other, the mechanical gripper closes; when the claws are far apart, the mechanical gripper opens.

[0008] The bottom wall of the fixed plate is provided with a slide rail, and the top wall of the claw is provided with a slide groove. The claw is slidably mounted on the fixed plate through the cooperation of the slide groove and the slide rail.

[0009] A push rod is hinged to the inner side of the chuck, and a hinge plate is hinged to the end of the push rod away from the chuck. The hinge plate is coaxial with the fixed plate, and the second power mechanism is disposed between the fixed plate and the hinge plate.

[0010] The outer side of the claw is provided with anti-slip protrusions.

[0011] The first power mechanism is a first cylinder, and the second power mechanism is a second cylinder.

[0012] The support column is provided with a T-shaped sliding groove, and the sliding arm is provided with a T-shaped sliding head. The sliding arm is guided and moved along the vertical direction and assembled on the support column through the cooperation of the T-shaped sliding head and the T-shaped sliding groove.

[0013] The left power mechanism is a first servo motor, and the right power mechanism is a second servo motor.

[0014] The rotation angle of both the first servo motor and the second servo motor is 180 degrees.

[0015] The outer periphery of the base of the tire gripper for a tire vulcanizing machine of this utility model has a tire gripping station, a vulcanizing station, and a tire unloading station. The left turntable, with its mechanical gripper, reciprocates between the tire gripping station and the vulcanizing station, and the right turntable, with its mechanical gripper, reciprocates between the vulcanizing station and the tire unloading station. Support columns are fixedly installed on both the left and right turntables. Sliding arms are mounted on the support columns and guided to move up and down in the vertical direction. The power driving the sliding arms to move up and down is a first power mechanism. Both sliding arms are equipped with openable and closable mechanical grippers, which are driven to open and close by a second power mechanism. The mechanical gripper on the left turntable is used to place the tire blank to be vulcanized into the vulcanizing machine, while the mechanical gripper on the right turntable is used to remove the vulcanized tire blank from the vulcanizing machine. During vulcanization, the mechanical gripper on the right turntable waits at the tire unloading station, while the mechanical gripper on the left turntable returns to the tire gripping station and waits. Once vulcanization is complete, the mechanical gripper on the right turntable moves to the vulcanizing station and removes the vulcanized tire blank from the vulcanizing machine. Simultaneously, the mechanical gripper on the left turntable grabs a new tire blank to be vulcanized from the tire gripping station, transports it to the vulcanizing station, and places it into the vulcanizing machine for vulcanization. This invention can simultaneously unload tire blanks from the vulcanizing machine and place new tire blanks to be vulcanized into it, resulting in shorter loading and unloading times and higher efficiency.

[0020] Specific embodiments of the tire gripper for tire vulcanizing machines involved in this utility model are described below. Figures 1-9The device includes a base 1 with mounting holes 20. These holes allow the tire gripper, specifically designed for tire vulcanizing machines, to be fixed in place, such as next to the vulcanizing machine, using additional bolts. This means the tire vulcanizing machine is detachable and can be used with different vulcanizing machines. The base 1 is equipped with a left turntable 2 and a right turntable 3, both rotatable relative to the base 1. Both turntables 2 and 3 can rotate around their own central axis. The left turntable 2 is driven by a left power mechanism, and the right turntable 3 is driven by a right power mechanism. The rotating mechanism has support columns 4 fixedly installed on both the left and right turntables 2 and 3. Slide arms 5 are mounted on the support columns 4, moving vertically along their respective axes. A first power mechanism drives the slide arms 5 to move vertically. Each slide arm 5 is equipped with an openable and closable mechanical gripper 6, which is driven to open and close by a second power mechanism. The mechanical grippers 6 are used to lift or remove the tire blank. When closed, the mechanical grippers 6 can extend into or exit the central hole of the tire blank to remove it. When open, the mechanical grippers 6... The system can support the tire blank outward from the center hole of the tire blank to lift it. During the rotation of the left turntable 2, its supporting column 4, sliding arm 5, and mechanical gripper 6 rotate together. During the rotation of the right turntable 3, its supporting column 4, sliding arm 5, and mechanical gripper 6 rotate together. The outer periphery of the base 1 has a tire gripping station, a vulcanizing station, and a tire unloading station. The left turntable 2, with its mechanical gripper 6, reciprocates between the tire gripping station and the vulcanizing station. The right turntable 3, with its mechanical gripper 6, reciprocates between the vulcanizing station and the vulcanizing station. The tire unloading station reciprocates. The left power mechanism reciprocates within a specific angle. When the left power mechanism rotates to its two extreme angles, the left turntable 2, along with its mechanical gripper 6, rotates to the tire gripping station and the vulcanizing station, respectively. The right power mechanism reciprocates within a specific angle. When the right power mechanism rotates to its two extreme angles, the right turntable 3, along with its mechanical gripper 6, rotates to the vulcanizing station and the tire unloading station, respectively. The mechanical grippers 6 on the left turntable 2 and the right turntable 3 are not simultaneously in the vulcanizing station. When the left turntable 2 rotates to the tire gripping station, its mechanical gripper 6 can lift the tire blank to be vulcanized. When the left turntable 2 rotates to the vulcanizing station, its mechanical gripper 6 can unload the tire blank to be vulcanized into the vulcanizing machine for vulcanization. When the right turntable 3 rotates to the vulcanizing station, its mechanical gripper 6 can lift the vulcanized tire blank from the vulcanizing machine. When the right turntable 3 rotates to the tire unloading station, its mechanical gripper 6 can unload the vulcanized tire blank.

[0021] Specifically, the mechanical gripper 6 has a fixed disk 9, and several claws 10 are evenly distributed along the circumference below the fixed disk 9. The claws 10 are slidably disposed on the fixed disk 9. When the claws 10 are close to each other, the mechanical gripper 6 closes; when the claws 10 are far apart, the mechanical gripper 6 opens.

[0022] Specifically, a slide rail 11 protrudes from the bottom wall of the fixed disk 9, and a slide groove 12 is provided on the top wall of the claw 10. The claw 10 is slidably mounted on the fixed disk 9 through the cooperation of the slide groove 12 and the slide rail 11.

[0023] Specifically, a push rod 13 is hinged to the inner side of the chuck 10, and a hinge plate 14 is hinged to the end of the push rod 13 away from the chuck 10. The hinge plate 14 is coaxial with the fixed plate 9, and a second power mechanism is disposed between the fixed plate 9 and the hinge plate 14. The second power mechanism can drive the hinge plate 14 to move closer to or away from the fixed plate 9 vertically. When the hinge plate 14 moves closer to the fixed plate 9, the chucks 10 move away from each other, and the mechanical gripper 6 opens; when the hinge plate 14 moves away from the fixed plate 9, the chucks 10 move closer to each other, and the mechanical gripper 6 closes.

[0024] Specifically, the outer side of the gripper 10 is provided with anti-slip protrusions 15. When the tire is lifted, the anti-slip protrusions 15 increase the friction between the gripper 10 and the tire blank, preventing the tire blank from falling off the mechanical gripper 6.

[0025] Specifically, the first power mechanism is the first cylinder 16, and the second power mechanism is the second cylinder 17. The cylinder body of the first cylinder 16 is fixed on the support column 4, and the piston rod of the first cylinder 16 is fixed on the sliding arm 5; the cylinder body of the second cylinder 17 is fixed on the sliding arm 5, and the piston rod of the second cylinder 17 passes through the through hole on the fixed plate 9 and is then fixed on the hinge plate 14.

[0026] Specifically, the support column 4 is provided with a T-shaped groove 18, and the sliding arm 5 is provided with a T-shaped sliding head 19. The sliding arm 5 is guided and moved along the vertical direction and assembled on the support column 4 through the cooperation of the T-shaped sliding head 19 and the T-shaped groove 18.

[0027] Specifically, the left power mechanism is the first servo motor 7, and the right power mechanism is the second servo motor 8. The base 1 has a left receiving hole and a right receiving hole. The housing of the first servo motor 7 is fixed in the left receiving hole, and the shaft of the first servo motor 7 is fixed on the left turntable 2; the housing of the second servo motor 8 is fixed in the right receiving hole, and the shaft of the second servo motor 8 is fixed on the right turntable 3.

[0028] Specifically, the rotation angle of both the first servo motor 7 and the second servo motor 8 is 180 degrees.

[0029] In the initial state, the mechanical gripper 6 on the left turntable 2 is in the tire gripping position, and the mechanical gripper 6 on the right turntable 3 is in the tire unloading position; the piston rod of the first cylinder 16 is at its maximum stroke, and the sliding arm 5 is at its highest point; the piston rod of the second cylinder 17 is at its maximum stroke, the pawls 10 are close together, and the mechanical gripper 6 is in the closed state. In use, the base 1 of the tire gripper for the tire vulcanizing machine is fixed to the ground foundation using the separately provided bolts, aligning its vulcanizing position with the vulcanizing position of the separately provided vulcanizing machine. Then, the first cylinder 16 on the left is activated, causing its piston rod to move to its minimum stroke position, driving the left sliding arm 5 to slide down to the lowest point to prepare to grip the tire blank to be vulcanized. Next, the second cylinder 17 on the left is activated, causing its piston rod to move to its minimum stroke position, driving the left mechanical gripper 6 to open and support the tire blank to be vulcanized. Then, the first cylinder 16 on the left is activated again, causing the left sliding arm 5 to slide back to the highest point. Then, the first servo motor 7 is activated, driving the left turntable 2 and the mechanical gripper 6 on it to move to the vulcanizing position. After that, the first cylinder 16 on the left is activated again, causing the left sliding arm 5 to slide back to the lowest point, and the second cylinder 17 on the left is activated, driving the left mechanical gripper 6 to close, thus unloading the tire blank to be vulcanized into the vulcanizing position. After that, the first cylinder 16 on the left, causing the left sliding arm 5 to slide back to the highest point. At the first point, the first servo motor 7 drives the left turntable 2, along with its mechanical gripper 6, back to the tire gripping station. After vulcanization, the second servo motor 8 is activated, driving the right turntable 3, along with its mechanical gripper 6, to rotate to the vulcanization station. Then, the first cylinder 16 on the right is activated, causing the right sliding arm 5 to slide to the lowest point to prepare to grip the vulcanized tire blank. Next, the second cylinder 17 on the right is activated, causing its piston rod to move to the minimum stroke position to drive the right mechanical gripper 6 to open, thus supporting the vulcanized tire blank. Then, the first cylinder 16 on the right is activated, causing the right sliding arm 5 to slide back to the highest point. Then, the second servo motor 8 is activated, driving the right turntable 3, along with its mechanical gripper 6, back to the tire unloading station. Then, the first cylinder 16 on the right is activated again, causing the right sliding arm 5 to slide back to the lowest point, and the second cylinder 17 on the right is activated, causing the right mechanical gripper 6 to close, thus unloading the vulcanized tire blank into the tire unloading station. Finally, the first cylinder 16 on the right is activated, causing the right sliding arm 5 to slide back to the highest point. This completes one tire loading and unloading operation. While the mechanical gripper 6 on the right removes the vulcanized tire blank, the mechanical gripper 6 on the left simultaneously removes the next tire to be vulcanized. At the same time, the second servo motor 8 drives the right turntable 3, with the mechanical gripper 6 on it, back to the tire unloading station, while the first servo motor 7 drives the left turntable 2, with the mechanical gripper 6 on it, to turn towards the vulcanization station.
