Description

Technical Field

[0001] This utility model relates to tire production auxiliary equipment, specifically a large tire flipping device. Background Technology

[0002] Currently, after the tires are vulcanized, large engineering tire companies in China use the tire loading mechanism built into the vulcanizing machine to place the large tires flat on the tire transport trolley in front of the vulcanizing machine. Then, the tire transport trolley transports the large tires to the pre-treatment station, where manual cleaning of tire hair and debris is performed. At this time, the large tires need to be stood upright to clean the tire hair and debris on both sides.

[0003] Because large engineering tires are heavy, generally weighing between 300 kg and 1200 kg, it is difficult to stand them upright by manpower. They need to be lifted by a crane in the factory building and secured with ropes, which is very inconvenient. Furthermore, if the crane needs to be used for vulcanizing machine maintenance or mold replacement, it will have to wait, resulting in low work efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a large tire flipping device that can replace manual labor and improve work efficiency.

[0005] A large tire-turning device capable of solving existing technical problems includes a lifting mechanism, a turning mechanism, and a clamping mechanism, the difference being:

[0006] 1. The lifting mechanism includes lifting plates symmetrically arranged on the left and right. Each lifting plate is mounted on the frame via front and rear linear guide rail pairs. A lifting cylinder is correspondingly provided on the frame to drive each lifting plate to move up and down.

[0007] 2. The flipping mechanism includes a turntable centrally mounted in each lifting plate via a rotating joint, and each lifting plate is provided with a flipping motor that drives the turntable to rotate via a gear transmission pair I.

[0008] 3. The clamping mechanism includes a fork arm clamping frame located inside each lifting plate. Each fork arm clamping frame is mounted on a corresponding turntable via guide rods and guide sleeves on both sides of the shaft. Each turntable is equipped with a clamping motor that drives each fork arm clamping frame to move left and right via a gear transmission pair II and a screw and nut transmission pair.

[0009] Furthermore, one structure of each linear guide pair includes a slidingly fitted linear guide and a slide block, wherein the linear guide is mounted on the frame and the slide block is mounted on the lifting plate.

[0010] Furthermore, one structure of each gear transmission pair I includes a meshing driving pinion I and a semi-circular large rack, wherein the driving pinion I is mounted on the rotating shaft of the reversing motor, and the semi-circular large rack is mounted on the turntable.

[0011] Furthermore, one structure of each guide rod and guide sleeve pair includes a slidingly fitted guide rod and a guide sleeve, wherein the guide sleeve is installed inside the turntable and the guide rod is installed on the fork arm clamping frame.

[0012] Furthermore, one structure of the lead screw and nut transmission pair includes a toothed nut screwed onto the lead screw, the toothed nut being centrally mounted inside the turntable, and the lead screw being mounted on the fork arm clamping frame; one structure of the gear transmission pair II includes a meshing driving large gear II and a driven small gear II, the driving large gear II being mounted on the rotating shaft of the clamping motor, and the driven small gear II being the toothed portion of the toothed nut exposed on the turntable.

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

[0014] The structure of this utility model's large tire flipping device adopts a positioning clamping form. The fork arm clamping frame achieves linear motion through gear transmission pair II and screw nut transmission pair to ensure applicability to large tires of different specifications. Large tires can be flipped through gear transmission pair I, filling a market gap and being easy to operate. Attached Figure Description

[0021] The technical solution of this utility model will be further described below with reference to the embodiments shown in the accompanying drawings.

[0022] The large tire flipping device of this utility model includes a lifting mechanism (left and right configuration), a flipping mechanism (left and right configuration), and a clamping mechanism (left and right configuration) based on the frame 2.

[0023] The frame 2 includes left and right symmetrical portal frames and front and rear crossbeams (left and right directions) connecting the left and right portal frames. Linear guide rails 8 are installed on the inner sides of the front and rear vertical beams of each portal frame. A lifting cylinder 3 is centrally mounted on the top crossbeam (front and rear direction) of each portal frame. Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown.

[0024] Each lifting mechanism includes a lifting plate 1 (square plate) located within each portal frame. Upper and lower sliding seats 9 are mounted on the front and rear end faces of the lifting plate 1. The upper and lower sliding seats 9 on the front face of the lifting plate 1 are slidably mounted on the front linear guide rail 8, and the upper and lower sliding seats 9 on the rear face of the lifting plate 1 are slidably mounted on the rear linear guide rail 8. The cylinder rods of each lifting cylinder 3, extending downwards (through the top crossbeam), are screwed to the top of the corresponding lifting plate 1. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown.

[0025] Each tilting mechanism includes a turntable 4 centrally mounted within a rotating hole in each lifting plate 1. The axial limiting end of the turntable 4 relies on a step on the turntable 4, and the other end relies on an annular baffle installed between the turntable 4 and the lifting plate 1. A coaxial semi-circular rack 11 is mounted on the lower inner side of each turntable 4. A tilting motor 5 with a rotary encoder is mounted at the lower front corner of the outer side of each lifting plate 1. The rotating shaft of each tilting motor 5 passes inward through the corresponding lifting plate 1. A driving pinion I 10 meshing with the semi-circular rack 11 is mounted on the extended end of the rotating shaft of the tilting motor 5. Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown.

[0026] Each clamping mechanism includes a fork-arm clamping frame 6 located inside each turntable 4. Each fork-arm clamping frame 6 is slidably mounted in a corresponding guide sleeve on each turntable 4 via guide rods 14 on both sides of the center of the turntable 4. A toothed nut 13 is installed inside the center of each turntable 4, and a lead screw 12 is screwed into the toothed nut 13. The inner end of each lead screw 12 is screwed to the corresponding fork-arm clamping frame 6, and a limit nut is screwed onto the outer end of each lead screw 12. The small gear portion of each toothed nut 13 is exposed inside the corresponding turntable 4. A clamping motor 7 with a rotary encoder is installed on the outer side of each turntable 4. The rotating shaft of the clamping motor 7 passes inward through the turntable 4, and the driving large gear II 15 that meshes with the small gear portion of each toothed nut 13 is installed on the extended end of the rotating shaft of the clamping motor 7. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown.

[0027] In the above structure, the left and right lifting plates 1 rise or fall synchronously; the left and right turntables 4 rotate 90° clockwise or 90° counterclockwise synchronously; and the left and right fork arm clamps 6 move synchronously relative to each other and move closer or further apart.

[0028] The operation mode of this utility model is as follows:

[0029] 1. When using, set the position of the limit nut on the screw 12 according to the diameter of different large tires 16, so that the distance between the left and right fork arm clamps 6 (in a horizontal position) is greater than the diameter of the large tire 16, and adjust the left and right fork arm clamps 6 to a suitable height.

[0030] 2. Use the tire transport trolley 17 to transport the large tire 16 to the middle of the left and right arm clamps 6.

[0031] 3. The left and right clamping motors 7 rotate synchronously, and through the gear transmission pair II (the driving large gear II 15 meshing with the toothed nut 13) and the screw nut transmission pair (the toothed nut 13 and the screw 12 that are screwed together), the left and right arm clamping frames 6 move towards each other to clamp the large tire 16.

[0032] 4. The cylinder rods of the left and right lifting cylinders 3 retract synchronously, and the left and right lifting plates 1 drive the left and right arm clamps 6 to lift the large tire 16 to a suitable flipping position.

[0033] 5. The left and right flipping motors 5 rotate synchronously, and through the left and right gear transmission pairs I (the driving pinion I 10 meshes with the semi-circular large rack 11), they drive the left and right turntables 4 and the left and right fork arm clamps 6 to rotate 90° clockwise, thereby rotating the horizontal large tire 16 into an upright state.

[0034] 6. Manually clean the large tires 16 of tire hair and debris.

[0035] 7. After the cleaning operation is completed, the left and right lifting cylinders 3 extend synchronously to lower the upright large tire 16 onto the tire transport trolley 17. The left and right clamping motors 7 reverse synchronously, driving the left and right arm clamping frames 6 to move in opposite directions (return to the initial position) and release the clamping of the large tire 16.

[0036] 8. After the large tire 16 is transferred out of the clean area by the tire transport trolley 17, the left and right arm clamps 6 are simultaneously reversed to the horizontal and raised back to the initial position, waiting for the delivery of the next large tire 16.
