Description

Technical Field

[0001] The present invention relates to the technical field of vulcanizing machine processing equipment, and more particularly to a tire vulcanizing gripping mechanism. Background Art

[0002] The tire vulcanization gripper is a device used to remove the tire from the vulcanizer. The function of the tire vulcanization gripper is to use a robotic arm and gripper to accurately remove the tire and place it in a designated location for subsequent operations.

[0003] After searching, the utility model patent with publication number CN213919233U discloses a gripping mechanism for a tire conveying device for a vulcanizer. The gripping mechanism is arranged at the rear of the vulcanizer frame and includes a truss column arranged on a vulcanization trench and at least one truss robot slidably mounted on the truss column. The truss column extends from a green tire storage area to a finished tire storage area. The truss robot includes at least one truss robot claw that can slide up and down and move left and right on the truss column to grasp green tires and finished tires. However, in the prior art, the vulcanizer manipulator is provided with a pair of front and rear manipulators. The traditional method is that the front manipulator grasps the green tire and the rear manipulator grasps the vulcanized tire. This method occupies a large space in the vulcanizer and wastes a certain amount of space. When the device is in use, the device has no limiting mechanism, making it difficult to limit the screw, resulting in the screw on the device being easily loosened after long-term use. In addition, the device has no sealing mechanism, making it difficult to seal the screw and rotating block, resulting in the screw and rotating block on the device being easily rusted. Therefore, improvement is needed. Summary of the Invention

[0039] In this embodiment, by pulling the slide rod 91 to move, after the slide rod 91 moves to the specified position, the screw 4, the annular sleeve 7 and the limiting groove 8 and other components are installed to the specified position on the device, and then the slide rod 91 is moved into the limiting groove 8, so that the screw 4 and other components are limited, preventing the screw 4 on the device from loosening after long-term use.

[0040] For details, please refer to Figure 6 The upper end of the sliding plate 94 is fixedly connected to a fixing block 95 , and the upper end of the fixing block 95 is fixedly connected to a pull ring 96 .

[0041] In this embodiment, the pull ring 96 is designed to drive the sliding plate 94 and other components to move.

[0042] For details, please refer to Figure 8An elastic card block 914 is clamped inside the second card slot 913 , and the elastic card block 914 is fixedly connected to the connecting rod 911 .

[0043] In this embodiment, the connection rod 911 can be limited by designing the elastic block 914 .

[0044] For details, please refer to Figure 6 One end of the spring 920 is fixedly connected to the slide rod 91 , and the other end of the spring 920 is fixedly connected to the connecting plate 2 .

[0045] In this embodiment, the spring 920 is designed so that the slide bar 91 has an elastic force.

[0046] Working principle: Before the device is used, the pull ring 96 is pulled to move in the direction away from the sliding block 93. The movement of the pull ring 96 drives the fixed block 95 to move. The movement of the fixed block 95 drives the sliding plate 94 to move. The movement of the sliding plate 94 drives the sliding block 93 and other components to move. The movement of the sliding block 93 drives the groove 97 and the slide rod 91 to move. The movement of the groove 97 drives the ball 98 to move. When the slide rod 91 moves, the spring 920 is compressed. After the slide rod 91 moves to the specified position, the moving rotating block 5 drives the screw rod 4 and the annular sleeve 7 to move. The screw 4 moves from the connecting plate 2 to contact the connecting piece 3, and then the rotating block 5 is rotated to drive the screw 4 and the annular sleeve 7 to rotate. The screw 4 rotates and generates a threaded motion with the connecting piece 3, thereby causing the screw 4 to produce a relative displacement. After the screw 4 rotates to the specified position in the connecting piece 3, the pull ring 96 is released, and the elastic force of the spring 920 pushes the slide rod 91 to move. The slide rod 91 moves The movement drives the sliding block 93 and other components to move, and the sliding rod 91 moves into the limiting groove 8, thereby limiting the screw 4 and other components to prevent the screw 4 on the device from loosening after long-term use. When lubricating oil needs to be added to the ball 98, the cover body 916 is removed from the oil filling hole 915, and the lubricating oil is poured from the oil filling hole 915 into the oil storage sponge 99, and the cover body 916 is installed back into the oil filling hole 915, and the handle 912 is moved downward. The handle 912 moves downward to drive the connecting rod 911 to move downward, and the connecting rod 911 moves downward to drive the elastic block 914 and the pressure rod 910 to move downward. The elastic block 914 moves downward and moves out of the second slot 913. The pressure rod 910 moves downward to compress the oil storage sponge 99, thereby causing the oil stored in the oil storage sponge 99 to flow from the oil outlet 917 and the connecting hole 918 into the groove 97, so that the oil stored on the ball 98 is added;

[0047] When the device is in use, the manipulator structure of the vulcanizer is redesigned, the front manipulator is removed and the intelligent logistics trolley is placed at the rear side of the vulcanizer, so that the rear manipulator can take care of grabbing the tire blank, loading the tire blank, grabbing the finished tire, and unloading the finished tire, thus reducing the occupied space;

[0048] When it is necessary to prevent the screw 4 and the rotating block 5 on the device from rusting, the mobile connecting sleeve 63 moves toward the rotating block 5, and the movement of the connecting sleeve 63 drives the sealing sleeve 64, the connecting block 62 and the first card groove 65 to move. The connecting block 62 moves into the connecting groove 61. During the movement of the connecting block 62, it contacts the card block 66, which causes the card block 66 to move toward the elastic sponge 69. The movement of the card block 66 drives the slide groove 67 and the friction block 611 to move. The movement of the card block 66 compresses the elastic sponge 69, and the friction block 611 moves. After friction occurs with the friction plate 612, the connecting block 62 and the first clamping groove 65 move to the specified positions in the connecting groove 61, thereby causing the connecting sleeve 63 and the sealing sleeve 64 to move to the specified positions. The elastic force of the elastic sponge 69 pushes the clamping block 66 to move, and the movement of the clamping block 66 drives the slide groove 67 and the friction block 611 to move. The clamping block 66 moves into the first clamping groove 65, thereby limiting the sealing sleeve 64 and other components, and thus sealing the screw 4 and the rotating block 5 to prevent the screw 4 and the rotating block 5 on the device from rusting.

[0049] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, and these changes should be covered by the scope of protection of the present invention.
