Description

Technical Field

[0001] This invention relates to the field of CNC machining center technology, and more specifically, to a fully automatic CNC machining center. Background Technology

[0002] CNC lathes and turning centers are high-precision, high-efficiency automated machine tools. Equipped with multi-station turrets or power turrets, these machines possess a wide range of machining capabilities, capable of processing complex workpieces such as straight cylinders, inclined cylinders, arcs, and various threads, grooves, and worm gears. They feature linear interpolation, circular interpolation, and various compensation functions, demonstrating excellent economic benefits in the mass production of complex parts. (Background information follows.)

[0003] In the current CNC lathe machining process, loading and unloading are generally done manually, which consumes a lot of labor costs and has low production efficiency. In order to improve production efficiency, robotic arms are also used for loading and unloading. However, when loading and unloading certain tubular parts, the robotic arms have low precision in loading and unloading parts, which makes it impossible to accurately load and unload parts, thus affecting the final machining accuracy of the parts.

[0004] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Summary of the Invention

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0022] As shown in the figure, a fully automatic CNC machining center includes two CNC lathes 1 arranged side by side. A guide rail 2 is provided on one side of the CNC lathe 1, and a robotic arm 3 is slidably connected to the guide rail 2. A suction cup 4 is provided at the movable end of the robotic arm 3. The center also includes a drive device (specifically a lead screw motor, which will not be described in detail in this embodiment) for driving the robotic arm 3 to slide along the guide rail 2. A material placement seat 5 is provided at one end of the guide rail 2, and a material receiving seat 6 is provided at the other end. A first vision detection device 7 is provided above the material placement seat 5, and its electrical signal is connected to the robotic arm 3. A first positioning component 8 is provided between the material placement seat and one of the CNC lathes 1, and a second positioning component 9 is provided between the two CNC lathes 1.

[0023] During production, the parts to be processed are placed on the placement seat 5. The surface of the placement seat is visually inspected by the first vision inspection device 7, and the visual signal is sent to the robotic arm 3. The robotic arm 3 accurately grasps the parts according to the visual signal and sends the parts into the first positioning component 8. After positioning the parts, the parts are grasped and placed into the adjacent CNC lathe 1. After the first processing is completed, the robotic arm 3 takes out the processed parts and moves towards another CNC lathe 1 through the drive device. The parts are first placed in the second positioning component 9 for positioning, and then placed into another CNC lathe 1. After processing is completed, the robotic arm 3 places the processed parts onto the receiving seat 6, thereby automatically completing the processing of the parts and automatically positioning the parts to ensure processing accuracy and improve processing efficiency.

[0024] The first positioning component 8 includes a frame 10, on the surface of which a positioning plate 11 is provided. A triangular groove 12 is formed on one side of the positioning plate 11, and a pusher 13 is also provided on the side of the frame 10 facing the opening of the triangular groove 12. Two positioning strips 14, parallel to the inner walls of the triangular groove 12, are provided within the positioning plate 11. A sliding groove 15 penetrates the inner wall of the positioning plate 11. A sliding rod 16, slidably connected to the positioning strips 14 within the sliding groove 15, is fixedly connected to each positioning strip. The component also includes a first driving member for driving the sliding rod 16. After a part is placed on the surface of the frame 10, the pusher 13 pushes the part towards the triangular groove 12, while the first driving member moves the two positioning strips 14 towards the part and presses them against the side wall of the part, thereby positioning the part and ensuring the accuracy of the robotic arm 3's gripping. (The second positioning component has the same structure as the first positioning component 8 and will not be described again in this embodiment.) A vertically arranged connecting rod 17 is fixedly connected to the bottom of the sliding rod 16. A sliding groove 15 penetrates the lower surface of the positioning plate 11 to allow the connecting rod 17 to slide. The frame 10 has a sliding groove 18 penetrating its bottom for the connecting rod 17 to slide. The sliding groove 18 is parallel to the sliding groove 15. The first driving component includes a driving rod 19 slidably connected to the bottom of the frame 10. A limiting groove 20 is formed along the length of the driving rod 19. The connecting rod 17 passes through and is slidably connected in the limiting groove 20. The component also includes a first cylinder 21 for driving the driving rod 19 to move in a direction perpendicular to the line connecting the two connecting rods 17. The first cylinder 21 drives the driving rod 19 to move, thereby driving the two connecting rods 17 to move along the sliding groove 18, thereby controlling the movement of the two positioning bars 14 closer to or further away from the part.

[0025] At the bottom of the frame 10, guide rods 22 perpendicular to the drive rod 19 are provided at both ends. Guide grooves are formed on the opposite sidewalls of the two guide rods 22 along their length. Guide blocks 23 are slidably connected to the drive rod 19 at both ends to ensure the stability of the drive rod 19 during operation.

[0026] The pusher component 13 includes a push rod 24 slidably connected to the surface of the frame 10, and a second cylinder 25 for driving the push rod 24 toward the positioning plate 11. An angle adjustment plate 26 is provided on the surface of the push rod 24 facing the positioning plate 11, and a second driving member is provided on the push rod 24 for driving the angle adjustment plate 26 to slide along the length of the push rod 24. When the second cylinder 25 pushes the push rod 24 toward the part and positions the part, the second driving member drives the angle adjustment plate 26 to rotate, thereby adjusting the angle position of the part.

[0027] The upper surface of the push rod 24 has a groove 27 along its length. A slider 28 is slidably connected within the groove 27. An angle adjustment plate 26 is fixedly connected to the slider 28. The second driving component includes a threaded rod 29 rotatably connected within the groove 27. The threaded rod 29 passes through and is threadedly connected to the slider 28. One end of the push rod 24 is equipped with a motor 30 for driving the threaded rod 29. The motor 30 drives the threaded rod 29, thereby causing the slider 28 and the angle adjustment plate 26 to move along the direction of the groove 27.

[0028] A rubber plate 31 is provided on the surface of the angle adjustment plate 26 facing the positioning plate 11 to increase the surface friction of the angle adjustment plate 26. The positioning strip 14 is smoothly arranged on the surface of the part. When the angle adjustment plate 26 is pressed against the surface of the part and moves, it can smoothly drive the part to rotate.

[0029] It also includes a control center 32, and a second vision detection device (not shown in the figure) is provided at the movable end of the robotic arm. The first vision detection device 7, the second vision detection device, the first cylinder 21, the second cylinder 25 and the motor are all electrically connected to the control center. The position of the processed parts can be observed in real time through the second vision detection device, and the robotic arm 3, the first positioning component 8 and the second positioning component can be controlled to accurately position the parts and place or grasp them.

[0030] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
