Description

Technical Field

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

[0002] In the field of machining, CNC lathes have become core processing equipment due to their high precision and stability. Loading and unloading, as key pre- and post-processing steps on lathes, directly affect production continuity, machining accuracy, and overall efficiency. With the transformation of manufacturing towards automation and intelligence, traditional manual or semi-automated loading and unloading methods are no longer sufficient to meet the demands of large-scale production. The research and application of automated loading and unloading robots for CNC lathes have become crucial for improving production automation and reducing manual intervention.

[0003] Currently, loading and unloading operations on CNC lathes are mostly done manually. Operators need to frequently travel between the raw material storage area and the lathe machining station, manually and accurately placing the materials to be processed into the lathe chuck. After processing, the finished products are manually removed. In some scenarios, simple fixtures are used to assist in positioning, but it is still necessary to manually monitor the material status and control the operation rhythm throughout the process. It is also necessary to strictly coordinate with the lathe machining process to avoid process disconnection.

[0004] However, manual operation involves large movements and a slow pace, and is susceptible to fatigue and lack of concentration, resulting in long loading and unloading intervals. This fails to fully utilize the high-speed processing capabilities of CNC lathes, leading to idle and wasteful equipment and making it difficult to meet the demand for efficient continuous processing in mass production. Therefore, an automatic loading and unloading robot for CNC lathes is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic loading and unloading robot for CNC lathes, which aims to solve the problem of low production efficiency in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic loading and unloading robot for CNC lathes, comprising a frame, wherein a loading and unloading mechanism is provided inside the frame, the loading and unloading mechanism includes a motor, the motor is fixedly installed on the right side of the frame, and the output end of the motor is fixedly connected to a first lead screw, which rotates through the right side of the frame and is fixedly connected to the left side of the inner wall of the frame. The inner wall of the frame is rotatably connected to a second lead screw. The outer wall of the first lead screw is fixedly fitted with a main gear, and the outer wall of the second lead screw is fixedly fitted with a driven gear, which meshes with the main gear. The outer walls of the first and second lead screws are threaded with moving blocks, and a pneumatic gripper is provided below the moving blocks.

[0007] As a further description of the above technical solution: a mounting plate is fixedly connected to the bottom of the movable block, and a first cylinder is fixedly connected to the top of the mounting plate, the output end of the first cylinder movably passing through the top of the mounting plate.

[0008] As a further description of the above technical solution: a mounting frame is fixedly connected to the bottom of the output end of the first cylinder, a second cylinder is fixedly connected to the side of the mounting frame, and the output end of the second cylinder moves through the side of the mounting frame and is fixedly connected to the pneumatic gripper.

[0009] As a further description of the above technical solution: a limiting rod is fixedly connected to the inner wall of the frame, and the limiting rod movably passes through the side of the moving block.

[0010] As a further description of the above technical solution: a collection mechanism is provided at the bottom of the frame, the collection mechanism includes a fixing plate, the fixing plate is fixedly connected to the bottom of the frame, and a collection frame is fixedly connected to the lower inner side of the fixing plate.

[0011] As a further description of the above technical solution: a spring is fixedly connected to the bottom of the inner wall of the collection frame, a buffer plate is fixedly connected to the top of the spring, and the buffer plate is slidably connected to the inner wall of the collection frame. A buffer pad is fixedly connected to the top of the buffer plate.

[0012] This utility model has the following beneficial effects: 1. In this utility model, the motor drives the first lead screw to rotate, and the main gear and the driven gear mesh to drive the second lead screw to rotate synchronously in the opposite direction. With the limit rod limiting the moving block, the height and front and rear positions of the pneumatic gripper are precisely adjusted by the first cylinder and the second cylinder to realize automatic loading and unloading of materials, greatly shortening the operation interval, avoiding the influence of human fatigue, giving full play to the processing efficiency of CNC lathe, and improving production efficiency and operation accuracy.

[0013] 2. In this utility model, the material protection is achieved through the collection mechanism at the bottom of the frame. The fixed plate firmly supports the collection frame. When the material slides down, it is first damped by the buffer pad, and then the impact force is further absorbed by the elastic cooperation of the buffer plate and the spring, which effectively avoids the material falling and being damaged. At the same time, the overall structure is compact and reasonable, the components are firmly connected, the operation is stable and reliable, the material loss in the production process is reduced, and the processing continuity is guaranteed.

[0017] Reference Figure 1 - Figure 3This utility model provides an embodiment of an automatic loading and unloading robot for a CNC lathe, comprising a frame 1, with a loading and unloading mechanism 2 inside the frame 1. The loading and unloading mechanism 2 includes a motor 21, which is fixedly mounted on the right side of the frame 1 to drive a first lead screw 22 to rotate. The output end of the motor 21 is fixedly connected to the first lead screw 22, and the first lead screw 22 rotates through the right side of the frame 1 and is fixedly connected to the left side of the inner wall of the frame 1 to drive one of the moving blocks 26 to move. A second lead screw 23 is rotatably connected to the inner wall of the frame 1 to drive the other moving block 26 to move. A main gear 24 is fixedly sleeved on the outer wall of the first lead screw 22, and a driven gear 25 is fixedly sleeved on the outer wall of the second lead screw 23. The driven gear 25 meshes with the main gear 24, so that the first lead screw 22 and the second lead screw 23 rotate synchronously in opposite directions. Moving blocks 26 are threadedly sleeved on the outer walls of the first lead screw 22 and the second lead screw 23, so that the two... The movable block 26 moves in the opposite direction. A limit rod 212 is fixedly connected to the inner wall of the frame 1. The limit rod 212 movably passes through the side of the movable block 26 to limit the movable block 26 so that it can only move horizontally and cannot rotate. A pneumatic gripper 211 is provided below the movable block 26 for gripping materials. A mounting plate 27 is fixedly connected to the bottom of the movable block 26 for mounting the first cylinder 28. The first cylinder 28 is fixedly connected to the top of the mounting plate 27. The output end of the first cylinder 28 movably passes through the top of the mounting plate 27 to drive the mounting frame 29 to rise and fall. The bottom of the output end of the first cylinder 28 is fixedly connected to the mounting frame 29 for mounting the second cylinder 210. The second cylinder 210 is fixedly connected to the side of the mounting frame 29, and the output end of the second cylinder 210 movably passes through the side of the mounting frame 29 and is fixedly connected to the pneumatic gripper 211 to drive the pneumatic gripper 211 to move back and forth.

[0018] Reference Figure 1 , Figure 3 The bottom of the frame 1 is provided with a collection mechanism 3, which includes a fixed plate 31. The fixed plate 31 is fixedly connected to the bottom of the frame 1 to support the collection frame 32. The collection frame 32 is fixedly connected to the lower inner side of the fixed plate 31 to collect materials that slip during the grabbing process. A spring 33 is fixedly connected to the bottom of the inner wall of the collection frame 32. A buffer plate 34 is fixedly connected to the top of the spring 33 and slides with the inner wall of the collection frame 32 to prevent materials from falling and getting damaged. A buffer pad 35 is fixedly connected to the top of the buffer plate 34 to further improve the buffering effect.

[0019] Working principle: After the motor 21 starts, it drives the first lead screw 22 to rotate. Since the main gear 24 on the first lead screw 22 meshes with the driven gear 25 on the second lead screw 23, the second lead screw 23 rotates synchronously in the opposite direction with the first lead screw 22. The limit rod 212 limits the moving block 26, so that the two moving blocks 26 move horizontally in opposite directions along the first lead screw 22 and the second lead screw 23 respectively. After the moving block 26 moves to the designated position, the first cylinder 28 drives the mounting frame 29 to rise and fall, adjusting the height of the pneumatic gripper 211. Then the second cylinder 210 pushes the pneumatic gripper 211 to move back and forth. The two pneumatic grippers 211 realize the loading and unloading of materials respectively. If the material slips during the gripping process, it will fall into the collection frame 32. The buffer pad 35 first contacts the material for initial buffering. The buffer plate 34 slides downward under the elastic action of the spring 33 to further absorb the impact force and avoid damage to the material.
