Description

Technical Field

[0001] The utility model relates to the technical field of bushing processing, in particular to an automatic feeding device for a bushing cutting machine. Background Art

[0002] In moving parts, parts wear due to long-term friction. When the clearance between the shaft and the hole wears to a certain extent, the parts must be replaced. Therefore, designers choose materials with lower hardness and better wear resistance as sleeves or bushings during design. This can reduce the wear of the shaft and the seat. When the sleeve or bushing wears to a certain extent, it is replaced. This can save the cost of replacing the shaft or seat. Generally speaking, the sleeve and the seat adopt an interference fit, and the shaft adopts a clearance fit. Because wear cannot be avoided anyway, the service life can only be extended, and shaft parts are relatively easy to process. Some new designers do not like this design, thinking that it increases costs during manufacturing. However, after a period of use, it still needs to be modified according to this method during maintenance, but the modification can easily reduce the accuracy of the equipment.

[0003] Some bushings exist in a tubular structure (hereinafter referred to as "bushing tubes") before being processed into finished products. Such bushings can be processed into finished products through simple processing such as cutting. Existing bushing tubes require manual loading when cutting. This loading method is slow and debris will be ejected during the cutting process, posing a safety hazard to the workers. This requires the use of a loading device for loading, but the existing loading device cannot load the bushing tubes individually. If too much material is loaded at one time, large errors will occur during the cutting process.

[0004] Therefore, those skilled in the art provide an automatic loading device for a bushing cutting machine to solve the problems raised in the above background technology. Utility Model Content

[0022] The frame 1 is a processing platform for bushing cutting commonly used on the market. The hopper 2 is installed above the frame 1. The conveying frame 3 can convey the bushing tube. The conveying frame 3 is set to be tilted downward. The bushing tube can roll down from the conveying frame 3 by its own gravity. There can be two guide plates 4. The receiving groove 5 is opened on the top of the guide plate 4. The receiving groove 5 is located in the middle and lower part of the guide plate 4. The partition plate is rotatably connected to the receiving groove 5. The width of the partition plate is adapted to the bushing tube. The partition plate is composed of a front baffle 6 and a rear baffle 7. When the front baffle 6 extends out of the receiving groove 5, the rear baffle 7 will gradually enter the receiving groove 5. When the front baffle 6 is extended to the maximum angle, the rear baffle 7 will completely enter the receiving groove 5. At this time, the rear bushing tube can enter between the front baffle 6 and the rear baffle 7 until the bushing tube can rest on the front baffle 6. When the rear baffle 7 extends out of the receiving groove 5, the front baffle 6 will gradually enter the receiving groove 5. When the rear baffle 7 is extended to the maximum angle, the front baffle 6 will completely enter the receiving groove 5. At this time, the bushing tube between the front baffle 6 and the rear baffle 7 will slide down from the conveying frame 3, and the rear bushing tube will be blocked by the rear baffle 7.

[0023] In one embodiment, specifically, the switching assembly includes a rotating shaft 8 connected to the middle of multiple partition plates, the rotating shaft 8 is rotatably connected to the guide plate 4, the rotating shaft 8 is fixedly matched with the partition plate, and one end of the rotating shaft 8 is connected to a toggle rod 9; the bottom of the guide plate 4 is slidably connected to a movable plate 10, and a long groove 11 is provided on the movable plate 10 to cooperate with the toggle rod 9. A telescopic rod 12 is installed at the bottom of the guide plate 4, and the output end of the telescopic rod 12 is connected to the movable plate 10. The rotating shaft 8 is rotatably connected to the conveyor frame 3. The rotating shaft 8 passes through the guide plate 4, and the rotating shaft 8 is connected to the partition plate for rotation. The rotation of the rotating shaft 8 can drive the partition plate to rotate. The toggle rod 9 is fixedly connected to one end of the rotating shaft 8. The movable plate 10 is slidably connected to the bottom of the guide plate 4. The long slot 11 is opened on the movable plate 10, and the toggle rod 9 is slidably connected to the long slot 11. The telescopic rod 12 can be purchased directly from the market. The telescopic rod 12 is fixedly connected to the guide plate 4. The telescopic rod 12 can drive the movable plate 10 to move when it is extended and retracted. The movement of the movable plate 10 can drive the partition plate to rotate through the rotating shaft 8, which can facilitate the loading of the bushing pipe.

[0024] Among them, the frame 1 is provided with a fixed seat 13 for fixing the cutting machine, and a plurality of receiving plates 14 are installed on the fixed seat 13; a positioning frame 15 is provided on both sides of the fixed seat 13, and a deceleration plate 16 is provided on the opposite side of the two positioning frames 15, and a spring 17 is provided between the deceleration plate 16 and the positioning frame 15. The fixed seat 13 is fixedly connected to the frame 1, and there are multiple receiving plates 14. The receiving plates 14 are fixedly connected to the fixed seat 13, and the bushing pipe falling from the guide plate 4 can enter the multiple receiving plates. The connecting plate 14 is used to facilitate the loading of the bushing tube. The positioning frame 15 is fixedly connected to both sides of the fixing seat 13. The two deceleration plates 16 are respectively hinged on the positioning frame 15. The spring 17 is located between the deceleration plate 16 and the positioning frame 15. The spring 17 is a lightweight spring 17 commonly found on the market. The force required for the deformation of the spring 17 is relatively small. When the bushing tube falls between the two deceleration plates 16, the bushing tube can push the two deceleration plates 16 away and then fall onto multiple receiving seats, which can reduce the speed of the bushing tube when it falls to the receiving seat and avoid deformation of the bushing tube.

[0025] On the basis of the above embodiment, specifically, the frame 1 is provided with a material guide push cylinder 18 for driving the sleeve pipe to be cut to move. The material guide push cylinder 18 can be purchased directly from the market. The material guide push cylinder 18 can push the sleeve pipe into the cutting machine, which can facilitate the cutting of the sleeve pipe by the cutting machine.

[0026] When in use, the bushing tube is placed on the conveying rack 3, and the bushing tube will roll downward on the inclined conveying rack 3 due to its own gravity. When the bushing tube at the bottom moves to the front baffle 6, the movable plate 10 is driven to move by the telescopic rod 12, and the movement of the movable plate 10 can drive the rotating shaft 8 to rotate through the toggle rod 9, and the rotation of the rotating shaft 8 can drive the partition plate to rotate. When the front baffle 6 completely enters the receiving groove 5, the bushing tube at the bottom loses its obstruction and rolls down between the two deceleration plates 16, and is placed between the front baffle During the process of plate 6 entering the receiving groove 5, the rear baffle 7 will gradually extend out of the receiving groove 5. The rear baffle 7 can block the subsequent bushing tubes to avoid loading multiple bushing tubes at one time. Then, the front baffle 6 is driven to reset by the telescopic rod 12 again, and the rear baffle 7 completely enters the receiving groove 5. At this time, the bushing tube closest to the front baffle 6 will pass over the rear baffle 7 and stop on the side of the front baffle 6. The falling bushing tube will push open the two retarder plates 16 and fall onto multiple receiving seats. Then, the bushing tube is pushed to the cutting machine for cutting through the material guide cylinder 18.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
