Description

Technical Field

[0001] This utility model relates to the field of loading and unloading technology, and in particular to an automatic loading and unloading device for CNC lathes. Background Technology

[0002] In the automated machining process of CNC lathes, the stability and reliability of the automatic loading and unloading device directly affect production efficiency and machining quality.

[0003] Traditional CNC lathe loading and unloading devices typically use a feeding trough in conjunction with a drive mechanism to transport cylindrical workpieces. The cylindrical workpiece is placed in the feeding trough in a horizontal position.

[0004] However, when cylindrical workpieces are placed in the feeding trough in a flat position, the frictional resistance between the workpiece and the inner wall of the feeding trough is relatively large. This is especially true when the workpiece surface is rough or the feeding trough is worn after long-term use. This can easily cause the workpiece to become stuck in the feeding trough due to obstructed movement. In addition, some cylindrical workpieces are relatively light or are not arranged in an orderly manner in the feeding trough. They may not be able to slide down smoothly by their own weight, and may even tilt or stack. This can also easily cause the workpiece to become stuck in the feeding trough due to obstructed movement, making it impossible for subsequent processes to proceed smoothly and affecting the processing progress.

[0005] Therefore, it is necessary to provide an automatic loading and unloading device for CNC lathes to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides an automatic loading and unloading device for CNC lathes, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides an automatic loading and unloading device for CNC lathes, including: a feeding trough and a drive mechanism. A cylindrical workpiece is laid flat in the feeding trough. The device also includes: a movable baffle, which is located below the feeding trough. A bushing rod 2 is hinged to one side of the movable baffle near the feeding trough, and a thin plate is hinged to the other end of the bushing rod 2. The thin plate is located inside the feeding trough and at the bottom of the cylindrical workpiece.

[0008] The movable baffle can slide under the action of the drive mechanism, and the thin plate slides inside the feeding trough and under the cylindrical workpiece through the hinge at both ends of the bushing rod.

[0009] Preferably, a limiting plate is fixedly connected to the top of the feeding trough, and anti-jamming grooves are provided on the front and rear sides of the feeding trough. The thin plate is adapted to the anti-jamming grooves, and a fixed shaft is fixedly connected to the bottom of the feeding trough.

[0010] Preferably, a material return bin is fixedly connected to the bottom of the feeding trough, a material discharge trough is fixedly connected to the right side of the material return bin, two support rods are fixedly connected between the bottom of the material discharge trough and the material return bin, a material retrieval gate is provided on the left side of the material return bin, and guide plates are fixedly connected to the inner walls of the front and rear sides of the material return bin.

[0011] Preferably, the driving mechanism includes: a cylinder and a bushing rod, the bushing rod being fixedly connected to the telescopic end of the cylinder, and the cylinder being hinged to a fixed shaft.

[0012] Preferably, the movable baffle is slidably connected to the guide groove plate, an L-shaped push plate is fixedly connected to the top of the movable baffle, a fixed shaft is fixedly connected to the top of the movable baffle, and the movable baffle is hinged to the bushing rod one and the bushing rod two through the fixed shaft two.

[0013] Preferably, guide frames are fixedly connected to both sides of the thin plate, the guide frames are slidably assembled at the bottom of the feeding trough, and a fixed shaft three is fixedly connected to the bottom of the guide frame, and the bushing rod two is hinged to the thin plate through the fixed shaft three.

[0014] Preferably, a drive chamber is provided between the feeding trough and the unloading hopper, and the drive mechanism is located inside the drive chamber.

[0015] Compared with related technologies, the automatic loading and unloading device for CNC lathes provided by this utility model has the following beneficial effects:

[0016] The thin plate is located at the bottom of the cylindrical workpiece. When the moving baffle slides down under the action of the drive mechanism, it drives the thin plate to slide synchronously under the workpiece through the bushing rod two. The friction between the top of the thin plate and the cylindrical workpiece drives the moving baffle to slide, avoiding the cylindrical workpiece from getting stuck in the feeding groove due to excessive friction. For cylindrical workpieces that are lighter or irregularly arranged, the sliding of the thin plate can adjust their posture by applying a horizontal thrust, preventing the workpiece from tilting or stacking, and ensuring that the workpiece slides down smoothly in the feeding groove. This fundamentally solves the jamming phenomenon caused by insufficient gravity or posture problems in traditional feeding methods, thereby improving the processing efficiency of CNC lathes.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 5 An automatic loading and unloading device for a CNC lathe includes: a feeding trough 10, a return bin 20, a drive bin 30, a drive mechanism 40, a loading mechanism 50, and an anti-jamming mechanism 60. The feeding trough 10 is fixedly installed on the top of the return bin 20, and the drive bin 30 is located between the feeding trough 10 and the return bin 20. The drive mechanism 40 is located inside the drive bin 30, the loading mechanism 50 is located on the right side of the feeding trough 10, and the anti-jamming mechanism 60 is located inside the feeding trough 10. The drive mechanism 40 can drive the loading mechanism 50 and the anti-jamming mechanism 60 to work. A cylindrical workpiece enters the loading mechanism 50 through the feeding trough 10. The drive mechanism 40 drives the loading mechanism 50 to move to the clamping part of the CNC lathe. The completed cylindrical workpiece falls into the return bin 20. While the drive mechanism 40 drives the loading mechanism 50 to move, it also drives the anti-jamming mechanism 60 to move, preventing the cylindrical workpiece from getting stuck in the feeding trough 10.

[0025] The top of the feeding trough 10 is fixedly connected to a limiting plate 11 to prevent the cylindrical workpiece from falling. Anti-jamming grooves 12 are provided on the front and rear sides of the feeding trough 10, and a fixed shaft 13 is fixedly connected to the bottom of the feeding trough 10. The left side of the feeding trough 10 is the inlet and the right side is the outlet. The feeding trough 10 itself has a slope that is higher on the left and lower on the right.

[0026] The right side of the unloading bin 20 is fixedly connected to the feeding chute 21. The finished workpiece is guided into the unloading bin 20 through the feeding chute 21. Two support rods 211 are fixedly connected between the bottom of the feeding chute 21 and the unloading bin 20 to support the feeding chute 21. The left side of the unloading bin 20 is provided with a material retrieval door 22, which can be opened to retrieve the finished workpiece. The inner walls of the front and rear sides of the unloading bin 20 are fixedly connected to guide plates 23, and the guide plates 23 are close to the discharge port of the feeding chute 10.

[0027] The drive mechanism 40 includes a cylinder 401 and a bushing rod 402. The bushing rod 402 is fixedly connected to the telescopic end of the cylinder 401. The bushing rod 402 has a bushing. The cylinder 401 can push the bushing rod 402 to move when it extends out of the telescopic end. The cylinder 401 is hinged to the fixed shaft 13.

[0028] The feeding mechanism 50 includes: a movable baffle 501, an L-shaped push plate 502, and a fixed shaft 503. The movable baffle 501 is slidably connected to the guide groove plate 23, and the L-shaped push plate 502 is fixedly connected to the top of the movable baffle 501. The L-shaped push plate 502 is located at the outlet of the feeding trough 10, and the workpiece waiting to be fed is located on the L-shaped push plate 502. The fixed shaft 503 is fixedly connected to the top of the movable baffle 501, and the bushing rod 402 is connected to the fixed shaft 503. 03 is hinged. When the cylinder 401 is activated to push the first bushing rod 402 to move, the first bushing rod 402 pushes the moving baffle 501 along the direction of the guide plate 23 through the second fixed shaft 503 and transports the workpiece to the clamping part of the CNC machine tool. The moving baffle 501 blocks the next workpiece to be loaded in the feeding groove 10. After the moving baffle 501 is reset, it will enter the L-shaped push plate 502. At this time, the cylinder 401 body will rotate along the first fixed shaft 13.

[0029] The anti-jamming mechanism 60 includes: a thin plate 601, a guide frame 602, a fixed shaft 603, and a bushing rod 604. The thin plate 601 has slopes on both sides and is slidably fitted inside the feeding trough 10, adapting to the anti-jamming groove 12. The guide frame 602 is fixedly connected to the thin plate 601 and slidably fitted to the bottom of the feeding trough 10. The bottom of the guide frame 602 is fixedly connected to the fixed shaft 603. The bushing rod 604 has two bushings; one end of the bushing rod 604 is hinged to the fixed shaft 603, and the other end... Two bushings at one end are hinged to the fixed shaft 503, and the bushing of the bushing rod 402 is located between the two bushings of the bushing rod 604. When the cylinder 401 pushes the moving baffle 501 to move and feed the material, causing the fixed shaft 503 to move, the bushing rod 604 moves accordingly, and drives the guide 602 and the thin plate 601 to slide on the feeding groove 10. The thin plate 601 slides at the bottom of the workpiece, which can ensure that the cylindrical workpiece is stably fed in the feeding groove 10, and avoid the cylindrical workpiece from getting stuck due to friction, insufficient weight, etc. when it is lying flat.

[0030] The sliding of the thin plate 601 can actively lift the bottom of the workpiece and apply a horizontal thrust to workpieces with large friction, tilting or stacking, so that their center of gravity is rebalanced, thereby correcting the posture deviation of the workpiece and ensuring that it slides smoothly down the feed trough 10.

[0031] The working principle of the automatic loading and unloading device for CNC lathes provided by this utility model is as follows:

[0032] The drive mechanism 40 uses cylinder 401 as the power source. Cylinder 401 is hinged to fixed shaft 13 at the bottom of the feeding trough 10. Its telescopic end is fixedly connected to bushing rod 402. Bushing rod 402 is hinged to the moving baffle 501 of the feeding mechanism 50 through fixed shaft 2 503. At the same time, fixed shaft 2 503 is hinged to the thin plate 601 of the anti-jamming mechanism 60 through bushing rod 2 604, forming a linkage structure of "cylinder 401-bushing rod 402-fixed shaft 2 503-bushing rod 2 604-thin plate 601".

[0033] When cylinder 401 extends, it pushes bushing rod 402 forward. Bushing rod 402 drives moving baffle 501 and bushing rod 604 to move synchronously through fixed shaft 503. When cylinder 401 retracts, each component resets in the opposite direction, forming a cycle drive.

[0034] The cylindrical workpiece to be processed lies flat in the feeding trough 10. The limiting plate 11 at the top of the feeding trough 10 prevents the workpiece from falling. The L-shaped push plate 502 at the right outlet receives the first workpiece. The moving baffle 501 slides in the guide plate 23 to prevent subsequent workpieces from rolling down due to the slope of the feeding trough 10, ensuring that only one workpiece is conveyed per feeding.

[0035] Cylinder 401 extends, pushing bushing rod 402 forward. Bushing rod 402 drives moving baffle 501 to slide along guide plate 23 towards the CNC lathe clamping part via fixed shaft 2 503. The L-shaped push plate 502 at the top of moving baffle 501 simultaneously pushes the workpiece to the clamping position, completing the feeding. At this time, moving baffle 501 temporarily blocks the next workpiece in the feeding groove 10 to the left side of the discharge port. Cylinder 401 retracts, moving baffle 501 drives L-shaped push plate 502 to reset, and the next workpiece in the feeding groove 10 slides onto L-shaped push plate 502 due to gravity, waiting for the next feeding.

[0036] The thin plate 601 of the anti-jamming mechanism 60 is located inside the feeding trough 10. Its two sides are slidably mounted in the anti-jamming groove 12 at the bottom of the feeding trough 10 through the guide frame 602 to ensure accurate sliding direction. The bottom of the thin plate 601 is hinged to the fixed shaft 503 through the bushing rod 604. When the moving baffle 501 moves, the bushing rod 604 drives the thin plate 601 to slide synchronously at the bottom of the workpiece. When the thin plate 601 slides at the bottom of the workpiece, the direct friction between the workpiece and the feeding trough 10 is converted into sliding friction between the thin plate 601 and the feeding trough 10, reducing resistance. The slope design on both sides of the thin plate 601 can guide the cylindrical workpiece to move smoothly and reduce collision friction. If the cylindrical workpiece tilts due to insufficient weight or irregular arrangement, the sliding of the thin plate 601 will lift the bottom of the workpiece and apply horizontal thrust to correct its posture and avoid stacking and jamming.

[0037] When the feeding mechanism 50 feeds the material, the thin plate 601 moves synchronously to ensure that the workpiece always slides down smoothly.

[0038] The workpiece processed by the CNC lathe is detached from the clamping part and guided to the unloading chute 21 on the right side of the feeding chute 10 to the unloading bin 20. The support rod 211 at the bottom of the unloading chute 21 provides support. The unloading door 22 on the left side of the unloading bin 20 can be opened to remove the finished workpiece.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
