Description

Technical Field

[0001] This application relates to the field of tire delivery technology, and in particular to a tire gripping and moving mechanism. Background Technology

[0002] Tires are annular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are usually mounted on metal rims, supporting the vehicle body, cushioning external impacts, making contact with the road surface, and ensuring the vehicle's driving performance.

[0003] The traditional method of transporting tires from one workstation to the next involves manual handling, sometimes using auxiliary equipment such as hoists. However, this still requires a significant number of personnel, resulting in low efficiency, high labor intensity, and safety hazards, which can easily lead to accidents. With industrial development, a more efficient transportation method is needed to meet the needs of tire production activities, improve transportation efficiency, reduce labor intensity and labor costs, and enhance worker safety.

[0007] The clamping assembly includes a clamping base plate hinged to the gripping frame. The clamping base plate is driven to swing by a fourth power unit mounted on the gripping frame. Several diameter-expanding plates are distributed along the circumference of the clamping base plate. The several diameter-expanding plates are driven by a fifth power unit mounted on the clamping base plate and are moved radially along the circumference of the clamping base plate.

[0008] By adopting the above technical solution, the gripping frame is vertically slidably mounted on the lifting base frame, realizing the vertical lifting and sliding of the clamping assembly. The lifting base frame is horizontally slidably mounted on the transverse rail frame, realizing the transverse sliding of the clamping assembly. This comprehensively achieves both lateral and vertical movement of the clamping assembly. The fifth power unit drives several expansion plates to move, thereby expanding or contracting outwards, which can tighten the tire and achieve tire gripping and placement. The fourth power unit drives the clamping assembly to swing, allowing the expansion plates to swing between the horizontal and vertical directions, suitable for gripping and placing tires that are laid down or upright. In summary, this achieves tire gripping and movement, completes tire transport, saves labor costs, improves transport efficiency, and enhances personnel safety.

[0009] Optionally, the fixture base plate has several third slide rails distributed along the circumference, and the tails of several of the diameter-expanding plates slide in cooperation with the third slide rails via third sliders.

[0010] By adopting the above technical solution, the expanding plate and the fixture base plate slide together in the form of a slider rail, ensuring a stable connection and sliding fit between the expanding plate and the fixture base plate.

[0011] Optionally, a central column is provided at the center of several of the expansion plates, and the several expansion plates are hinged to the central column by a strut. The central column is driven by a fifth power unit to move axially.

[0012] By adopting the above technical solution, the central column can be moved circumferentially by the second power unit, and several expansion plates can be moved simultaneously by the struts, so as to realize the synchronous movement of several expansion plates and achieve diameter change.

[0013] Optionally, the expansion plate is provided with a plurality of strut hinge holes, and there are at least two struts. One end of the strut is hinged to the strut hinge hole, and the other end of the strut is hinged to the central column through a strut hinge seat.

[0015] Optionally, the support rod includes an end rod and an intermediate rod. The intermediate rod has an internal threaded hole, and one end of the end rod has an external thread. There are two end rods, which are threaded to both ends of the intermediate rod respectively.

[0016] By adopting the above technical solution, the overall length of the support rod can be adjusted through the threaded connection of the end rod and the middle rod, thereby adjusting the movable range of the expansion plate and realizing the adjustment of the expansion radius of the expansion plate to accommodate tires of different sizes.

[0017] Optionally, a first slide rail is provided on the transverse rail frame, and a first slider is provided on the lifting base frame, with the first slider slidingly engaging with the first slide rail; a rack is provided on the transverse rail frame in the same direction as the first slide rail, and a first power unit is provided on the lifting base frame, with the first power unit driving the gear meshing with the rack to rotate.

[0018] By adopting the above technical solution, the lifting base frame is connected to the transverse rail frame through the slider rail to achieve a sliding fit, which is stable and reliable; the lifting base frame is driven to slide through the gear and rack meshing transmission, which is also stable and reliable.

[0019] Optionally, a second slider is provided on the lifting base frame, and a second slide rail is provided on the gripping frame. The second slider and the second slide rail are slidably engaged. A threaded sleeve is rotatably provided on the lifting base frame, and a driven pulley is coaxially fixedly provided with the threaded sleeve. A second power unit is provided on the lifting base frame. The second power unit drives the active pulley to rotate, and a synchronous belt is provided between the active pulley and the driven pulley. A lead screw is threadedly engaged with the threaded sleeve, and the bottom end of the lead screw is connected to the gripping frame.

[0020] By adopting the above technical solution, the gripper is connected to the lifting base frame through the slider rail to achieve sliding engagement, which is stable and reliable; the gripper slides through the threaded engagement of the lead screw and the lead sleeve. This method is stable, reliable and highly accurate, and can also achieve a self-locking function to prevent the gripper from sliding unexpectedly and causing accidents.

[0021] Optionally, a third power unit is provided on the lifting base frame, the third power unit including a lifting cylinder, and the end of the telescopic rod of the lifting cylinder is connected to the gripping frame.

[0022] By adopting the above technical solution and setting up the lifting cylinder, the gripping frame can be directly driven to rise and fall.

[0023] Optionally, the fourth power unit includes a fourth cylinder, and there are two fourth cylinders. The two fourth cylinders are respectively hinged to both sides of the gripping frame, and the telescopic rods of the two fourth cylinders are respectively hinged to both sides of the clamp base plate.

[0024] By adopting the above technical solution and setting two fourth cylinders, it is possible to ensure that the clamping assembly swings while ensuring the stability of the clamping assembly swing, improving control accuracy, and preventing the clamping assembly from shaking.

[0025] Optionally, the head of the expanding plate is provided with an outward-flaring block, and a limiter is provided near the tail of the expanding plate, and the outer periphery of the expanding plate is arc-shaped.

Through the fourth power unit, the clamping assembly can be oscillated, allowing the expansion plates to swing between the transverse and vertical directions, suitable for gripping and placing tires that are laid down or upright. In summary, this achieves the gripping and movement of tires, completing tire transport, saving labor costs, improving transport efficiency, and enhancing personnel safety.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] The following is in conjunction with the appendix Figures 1 to 8 This application will be described in further detail.

[0043] This application discloses a tire gripping and moving mechanism.

[0044] Example 1

[0045] Reference Figures 1 to 7 A tire gripping and moving mechanism includes: a transverse rail frame 1, a lifting base frame 2, a gripping frame 6, and a clamping assembly.

[0046] The transverse rail frame 1 can be composed of rectangular tubes welded together, including the top rail frame and the support legs that support the rail frame.

[0047] A lifting base frame 2 is slidably mounted on a transverse rail frame 1. Two parallel slide rails 3 are mounted on the top rail frame. A first slider is mounted on the lifting base frame 2, and the first slider slides in engagement with the first slide rails 3. A rack 4 is mounted on the transverse rail frame 1 in the same direction as the first slide rails 3. A first power unit 5, which can be a first motor reducer, is mounted on the lifting base frame 2. Powered by a motor, the first power unit 5 drives the gear meshing with the rack 4 to rotate. The lifting base frame 2 is connected to the transverse rail frame 1 via the slider and slide rail, achieving a stable and reliable sliding engagement. The sliding of the lifting base frame 2 is achieved through the meshing transmission of the rack and gear 4, ensuring a stable and reliable engagement.

[0048] A gripping frame 6 is vertically slidably mounted on the lifting base frame 2. A second slider 7 is mounted on the lifting base frame 2. Two second slide rails 8 are parallel and spaced apart on the gripping frame 6. The second slider 7 and the second slide rails 8 are in sliding engagement. The gripping frame 6 is connected to the lifting base frame 2 through the slider and slide rails, achieving a stable and reliable sliding engagement.

[0049] A threaded sleeve 9 is rotatably mounted on the lifting base frame 2, and a driven pulley 10 is coaxially fixed to the threaded sleeve 9. A second power unit 11 is mounted on the lifting base frame 2. The second power unit 11 can be a second motor reducer unit, using motor power. The second power unit 11 drives the active pulley to rotate, and a synchronous belt is provided between the active pulley and the driven pulley 10. A lead screw 12 is threadedly engaged with the threaded sleeve 9, and the bottom end of the lead screw 12 is connected to the gripping frame 6. The sliding of the gripping frame 6 is achieved through the threaded engagement between the lead screw 12 and the threaded sleeve 9. This method is stable, reliable, and highly accurate, and can achieve a self-locking function to prevent accidental sliding of the gripping frame 6 and the occurrence of accidents.

[0050] The gripper assembly is located at the bottom of the gripper frame 6 and is used to grip the tire (the object to be gripped).

[0051] The fixture assembly includes a fixture base plate 13, a fourth power unit 14, an expansion plate 16, a fifth power unit 19, and a center column 17.

[0052] The fixture base plate 13 is hinged to the gripper frame 6. The fourth power unit 14 can be a fourth cylinder. There are two fourth cylinders, which are respectively hinged to both sides of the gripper frame 6. The extension rods of the two fourth cylinders are respectively hinged to both sides of the fixture base plate 13. By setting two fourth cylinders, the fixture base plate 13 is driven to swing up and down through the cylinder power, which can ensure the swing of the fixture assembly, while ensuring the stability of the swing of the fixture assembly, improving the control accuracy, and avoiding the shaking of the fixture assembly.

[0053] Four third slide rails 15 are distributed circumferentially on the fixture base plate 13, and the four slide rails are arranged radially. The tails of the four expansion plates 16 are slidably engaged with the third slide rails 15 through third sliders. The expansion plates 16 and the fixture base plate 13 are slidably engaged through the form of slider slide rails, ensuring a stable connection and sliding engagement between the expansion plates 16 and the fixture base plate 13. The center post 17 is set on the fixture base plate 13 at the center position of the four expansion plates 16. The four expansion plates 16 and the center post 17 are hinged to each other through support rods 18. Multiple support rod hinge holes are opened on the expansion plates 16. There are two support rods 18. One end of the support rod 18 is hinged to the support rod hinge hole, and the other end of the support rod 18 is hinged to the center post 17 through the support rod hinge seat. The multiple support rods 18 enable a more stable connection with the expansion plates 16, ensuring the stability of the expansion plates 16. The fifth power unit 19 is mounted on the fixture base plate 13 and drives the central column 17 to move axially. The fifth power unit 19 can be a fifth cylinder, which drives the central column 17 to move using cylinder power. By driving the central column 17 to move circumferentially through the fifth power unit 19, the four expansion plates 16 can be moved simultaneously through the support rod 18, so that the four expansion plates 16 can move synchronously, expanding outward or converging inward to achieve diameter change.

[0054] The support rod 18 includes an end rod and an intermediate rod. The intermediate rod has an internally threaded hole, and one end of the end rod has an external thread. There are two end rods, which are threaded to both ends of the intermediate rod respectively. By adjusting the threaded connection between the end rod and the intermediate rod, the overall length of the support rod 18 can be adjusted, thereby adjusting the movable range of the expansion plate 16 and realizing the adjustment of the expansion radius that the expansion plate 16 can expand to accommodate tires of different sizes.

[0055] An outward folding block 20 is provided at the head of the expansion plate 16, which folds outward. The outward folding block 20 at the head of the expansion plate 16 can limit the tire when the expansion plate 16 supports the tire, thus preventing the tire from falling off.

[0056] A limiter 21 is provided near the tail of the expansion plate 16. This limiter can be a rubber wheel. By setting the limiter 21 at the tail of the expansion plate 16, the expansion plate 16 is prevented from being inserted too much into the tire when gripping the tire, thus reducing the risk of damage.

[0057] The outer periphery of the expansion plate 16 is arc-shaped, which can ensure contact between the expansion plate 16 and the tire, increase the contact surface, and ensure stable gripping.

[0058] The gripping frame 6 is vertically slidable on the lifting base frame 2, enabling the clamping assembly to slide vertically. The lifting base frame 2 is horizontally slidable on the transverse rail frame 1, enabling the clamping assembly to slide horizontally. This combined achieves both horizontal and vertical movement of the clamping assembly. The fifth power unit 19 moves several expansion plates 16, expanding or contracting them outwards to tighten the tire, thus enabling the gripping and placement of the tire. The fourth power unit 14 causes the clamping assembly to swing, allowing the expansion plates 16 to swing between horizontal and vertical directions, suitable for gripping and placing tires that are laid down or upright. In summary, this achieves tire gripping and movement, completing tire transport, saving labor costs, improving transport efficiency, and enhancing personnel safety.

[0061] A third power unit 22 is provided on the lifting base frame 2. The third power unit 22 includes a lifting cylinder. The end of the telescopic rod of the lifting cylinder is connected to the gripping frame 6. By setting up the lifting cylinder, the gripping frame 6 can be directly driven to be raised and lowered.
