Description

Technical Field

[0001] This utility model relates to the field of manufacturing technology, and in particular to an automatic feeding device for CNC machine tools. Background Technology

[0002] With the rapid development of the manufacturing industry, computer numerical control machine tools (CNC machine tools) have been widely used in the field of mechanical processing due to their significant advantages such as high precision, high efficiency and high degree of automation. In the CNC machine tool processing, the loading process is the starting point of the entire production process, and its efficiency and stability directly affect the subsequent processing quality and overall production efficiency.

[0003] Existing automatic feeding systems for machine tools typically involve placing iron bars on a feeding device, which then uses multiple power components to push the bars one by one into the placement slot before conveying them to the machine tool's feed inlet. However, during the conveying process, the iron bars are easily affected by external forces such as vibration, resulting in displacement or detachment. This leads to inaccurate feeding positioning or interrupted feeding, severely affecting the stability of the conveying process and the continuity of processing, thus reducing processing efficiency.

[0004] Therefore, it is necessary to design an automatic feeding device for CNC machine tools that can automatically convey and flip iron bars for feeding while clamping and fixing the iron bars to prevent them from shifting or falling off, thereby improving the stability of conveying and processing efficiency. Utility Model Content

An adjusting component for adjusting the angle of iron bars is provided between the clamping component and the feeding frame 3.

[0021] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the conveying assembly includes a guide plate 7, a slide bar 8, a first telescopic spring 9, and a slide rail 10. The left and right sides of the feeding frame 3 are slidably connected to the slide bar 8. The upper side of the slide bar 8 is connected to the guide plate 7. The guide plates 7 are all folded to facilitate compression. The slide bar 8 is connected to the feeding frame 3 by the first telescopic spring 9. The lower part of the slide bar 8 is connected to the slide rail 10.

[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the clamping assembly includes a placement slot 11, rollers 111, a second sliding frame 12, a second telescopic spring 13, a clamping frame 14, and a second pulley 15. The placement slot 11 is rotatably connected to the slide rail 10. Rollers 111 are rotatably connected to both the left and right sides of the placement slot 11. The rollers 111 are in contact with the slide rail 10. The rollers 111 are all made of rubber and have good wear resistance. The second sliding frame 12 is slidably connected to the middle of the placement slot 11. The second telescopic spring 13 is connected between the second sliding frame 12 and the placement slot 11. The clamping frame 14 is rotatably connected to both the front and rear sides of the second sliding frame 12. The clamping frame 14 is rotatably connected to the placement slot 11. The second pulley 15 is rotatably connected to the upper part of the clamping frame 14.

[0023] like Figure 1 , Figure 2 and Figure 5As shown, the adjustment assembly includes a rack 16, a common gear 17, and a bevel gear 18. The rack 16 is connected to the lower right side of the feeding frame 3, and the common gear 17 is rotatably connected to the lower right side of the slide rail 10. The common gear 17 meshes with the rack 16. The left side of the common gear 17 and the lower side of the placement groove 11 are both connected to bevel gears 18, and the two bevel gears 18 mesh with each other.

[0024] This device can be used when automatic feeding of iron bars is required for CNC machine tool processing. The device is installed on the machine tool via mounting plate 1. The iron bar is then placed into the feeding frame 3, and slides down the frame onto the first sliding frame 5. Next, the processor activates the trackless cylinder 2 via the control module, causing the slider on the trackless cylinder 2 to move, which in turn moves the feeding frame 3, causing the second cylinder 61 to move to the height of the machine tool's feed inlet. After reaching the appropriate height, the trackless cylinder 2 is closed, and then the first cylinder 4 is activated, which in turn moves the first sliding frame 5. The frame 5 moves, blocking the iron bars above the lowest iron bar via the first sliding frame 5. Simultaneously, the lower part of the feeding frame 3 opens, allowing the lowest iron bar to slide onto the placement slot 11 and contact the second sliding frame 12, pressing it to move. The second telescopic spring 13 is stretched, causing the clamping frame 14 and the second pulley 15 to rotate and clamp the iron bar. As the first sliding frame 5 moves, it drives the first pulley 6 to move and rotate, contacting and pressing the guide plate 7. This causes the sliding rod 8 to move downwards, and the first telescopic spring... 9 is compressed, which in turn causes the slide rail 10 and the placement groove 11 to move downwards, so that the iron rod moves downwards to the position of the second cylinder 61, causing the ordinary gear 17 to move downwards. The ordinary gear 17 meshes with the rack 16, causing the ordinary gear 17 to rotate, which in turn drives the corresponding bevel gear 18 to rotate. The two bevel gears 18 mesh with each other, causing the second sliding frame 12 to rotate, which in turn causes the placement groove 11 to rotate along the slide rail 10, causing the roller 111 to rotate, which in turn drives the clamping frame 14 and the second pulley 15 to rotate, causing the plate to rotate 90 degrees. The guide plates 7 are all folded, and the rollers 111 are all made of rubber. Then, the second cylinder 61 is started. The extension end of the second cylinder 61 moves and pushes the iron bar to move and insert it into the machine tool feed port, disengaging it from the second sliding frame 12. This causes the second pulley 15 to rotate, the second extension spring 13 to rebound, and the second sliding frame 12 to move in the opposite direction and reset. This causes the clamping frame 14 and the second pulley 15 to move in the opposite direction and reset. Then, the second cylinder 61 operates in the opposite direction, causing the extension end of the second cylinder 61 to move and reset. Finally, the iron bar is processed and removed by the operation of the components on the machine tool.

[0025] During processing, the first cylinder 4 operates in reverse, causing the first sliding frame 5 to move in reverse and reset, blocking the lower part of the feeding frame 3. This causes the iron bar to slide downwards, simultaneously causing the first pulley 6 to move in reverse and reset, disengaging from the guide plate 7. The first telescopic spring 9 rebounds, causing the slide rod 8 and guide plate 7 to move in reverse and reset. This also causes the slide rail 10 and placement groove 11 to move upwards, causing the ordinary gear 17 to move upwards and reset. The ordinary gear 17 meshes with the rack 16, causing the ordinary gear 17 to rotate in reverse, which in turn causes the placement groove 11 to rotate in reverse and reset. This causes the roller 111, clamping frame 14, and second pulley 15 to rotate and reset. The above operation is then repeated to convey and clamp the next iron bar, thus automatically conveying and flipping the iron bar for feeding while clamping and fixing it to prevent displacement or detachment, improving the stability of conveying and processing efficiency.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
