Description

Technical Field

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

[0002] In existing CNC lathe machining processes, traditional loading and unloading methods mainly rely on manual operation. Each operator can only be responsible for loading and unloading one CNC lathe. This production mode is particularly inefficient in mass production. First, manual loading and unloading not only limits the improvement of production efficiency, making it difficult for overall production capacity to meet market demand; second, frequent loading and unloading operations are extremely labor-intensive for workers. After working for a long time, workers are prone to fatigue. In this high-intensity working environment, even slight carelessness by workers can lead to workplace accidents, making automated loading and unloading impractical. Therefore, we propose an automatic loading and unloading device for CNC lathes. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic loading and unloading device for CNC lathes, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic loading and unloading device for a CNC lathe, comprising a base, wherein a first rack and a second rack are slidably mounted on the top two sides of the base, the teeth of the first rack and the second rack are arranged opposite to each other, a speed-changing gear is provided between the first rack and the second rack, the speed-changing gear is rotatably mounted on the top of the base, the teeth on both sides of the speed-changing gear mesh with the first rack and the second rack respectively, a support plate is fixedly connected to one side of the top of the base, and a feeding pipe is fixedly connected to the outer wall of the support plate;

[0005] The second rack is fitted onto the outer wall of the feeding top rod. A discharge track is fixedly connected to one side wall of the base. Parts are provided in the inner cavity of the discharge track. The feeding top rod is positioned directly opposite the discharge port of the discharge track. The discharge track is located on one side of the hydraulic chuck. A discharge assembly is installed on one side of the hydraulic chuck.

[0006] By adopting the above technical solution, the parts are first transported to the end of the unloading track via the unloading track. Then, the X-axis slide table drives the entire device to move. When it moves to the hydraulic chuck, the adjusting bolt can push the first rack to move, thereby driving the speed-changing gear to rotate. The speed-changing gear drives the second rack to move, thereby driving the feeding rod to move, thus pushing the parts into the hydraulic chuck, thereby realizing loading. During unloading, the unloading pipe is aligned with the hydraulic chuck by adjusting the movement of the X-axis and Y-axis. Then, by releasing the hydraulic chuck, the unloading assembly can unload the parts into the unloading pipe.

[0007] In a preferred embodiment of the present invention, the unloading assembly includes a sleeve fixedly installed on one side of the hydraulic chuck, a matching unloading push rod is inserted into the inner cavity of the sleeve opening, a first spring is fixedly connected to the inner end of the unloading push rod, and the other end of the first spring is fixedly connected to the end face of the inner cavity of the sleeve.

[0008] By adopting the above technical solution, during unloading, the material unloading pipe is aligned with the hydraulic chuck by moving the X-axis and Y-axis. Then, the hydraulic chuck is released, and the first spring pushes the unloading rod to move, thereby pushing the parts into the unloading pipe and realizing automated unloading.

[0009] In a preferred embodiment of this utility model, a micro switch contact is fixedly fitted on the outer wall of one end of the feeding top rod. A micro switch is installed on one side of the top of the base near the micro switch contact. The micro switch is fixedly connected to the second rack via a mounting bracket. A sliding block adapted to a sliding cavity opened in the inner cavity of the second rack is fixedly fitted on the outer wall of the feeding top rod. A second spring is fixedly connected to one side wall of the sliding block. The second spring is sleeved on the feeding top rod and fixedly connected to the other end of the second rack and the inner wall of the sliding cavity.

[0010] By adopting the above technical solution, the micro switch and the industrial control computer of the machine tool are electrically connected. When the part is being fed, if there is jamming or debris causing the feeding to be incomplete, the second spring on the feeding rod is compressed, the micro switch contact is displaced, and the micro switch output signal is connected in parallel with the pause button circuit of the CNC lathe, commanding the equipment to pause and alarm, thus ensuring the reliability of production.

[0011] In a preferred embodiment of this utility model, the adjusting bolt and the threaded hole on the end face of the first rack engage.

[0012] In a preferred embodiment of this utility model, a fixed base plate is fixedly connected to the bottom of the base, and the fixed base plate has mounting holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This application discloses an automatic loading and unloading device for a CNC lathe. By fixing the device to the X-axis slide of the lathe, the workpiece can be fed into the hydraulic chuck along the unloading track. Then, the device is moved so that the adjusting bolt abuts against the hydraulic chuck. Under the action of gear drive, the feeding rod pushes the workpiece into the hydraulic chuck and pushes the unloading rod to compress the spring, thus completing the loading. During unloading, the hydraulic chuck is released, and the material is pushed into the discharge pipe by the spring pushing the unloading rod. This achieves automated loading and unloading, which is beneficial to improving processing efficiency, reducing the labor intensity of workers, and preventing work-related accidents.

[0023] Please see Figure 1-5This utility model provides a technical solution: an automatic loading and unloading device for a CNC lathe, including a base 7, on which a first rack 2 and a second rack 15 are slidably mounted on the top two sides of the base 7 respectively, the teeth of the first rack 2 and the second rack 15 are arranged opposite to each other, and a speed-changing gear 3 is arranged between the first rack 2 and the second rack 15. The speed-changing gear 3 is rotatably mounted on the top of the base 7, and the teeth on both sides of the speed-changing gear 3 mesh with the first rack 2 and the second rack 15 respectively.

[0024] The second rack 15 is fitted onto the outer wall of the feeding push rod 9. A discharge track 1 is fixedly connected to one side wall of the base 7. A part 10 is provided in the inner cavity of the discharge track 1. The feeding push rod 9 is positioned directly opposite the discharge port of the discharge track 1. The discharge track 1 is located on one side of the hydraulic chuck 14. A sleeve 18 is fixedly installed on one side of the hydraulic chuck 14. A matching discharge push rod 11 is inserted into the inner cavity of the sleeve 18. A first spring 19 is fixedly connected to the inner end of the discharge push rod 11. The other end of the first spring 19 is fixedly connected to the inner end face of the sleeve 18. A support plate is fixedly connected to one side of the top of the base 7. A discharge pipe 12 is fixedly connected to the outer wall of the support plate.

[0025] It should be understood that in actual use, the part 10 is first transported to the end of the unloading track 1, and then the entire device is moved by the X-axis slide table. When it moves to the hydraulic chuck 14, the adjusting bolt 13 can push the first rack 2 to move, thereby driving the speed change gear 3 to rotate. The speed change gear 3 drives the second rack 15 to move, thereby driving the feeding push rod 9 to move, thus pushing the part 10 into the hydraulic chuck 14, thereby realizing loading. During loading, the part 10 will push the unloading push rod 11 from... The compression of the first spring 19 stores energy, and then the hydraulic chuck 14 clamps the part 10. The X slide is then moved away from the hydraulic chuck 14, and the Y-axis sliding device is used to move the processing mechanism to the workpiece for processing without affecting it. During unloading, the feeding pipe 12 is aligned with the hydraulic chuck 14 by moving the X and Y axes. Then the hydraulic chuck 14 is released, and the first spring 19 pushes the feeding rod 11 to move, thereby pushing the part 10 into the feeding pipe 12, thus realizing automated loading and unloading.

[0026] Furthermore, a fixed base plate 8 is fixedly connected to the bottom of the base 7. The fixed base plate 8 has mounting holes, and the fixed base plate 8 makes it convenient to install and fix the entire device.

[0027] Furthermore, the threaded hole on the end face of the adjusting bolt 13 engages with the threaded hole of the first rack 2, thereby rotating the adjusting bolt 13 to adjust the length of the extended bolt 13, so that the moving distance of the first rack 2 can meet the moving distance requirements when the hydraulic chuck 14 abuts.

[0028] like Figure 1 and 2 As shown; a micro switch contact 5 is fixedly mounted on the outer wall of one end of the feeding rod 9, and a micro switch 6 is installed on one side of the top of the base 7 near the micro switch contact 5. The micro switch 6 is fixedly connected to the second rack 15 through the mounting bracket 4. A sliding block 16 that matches the sliding cavity opened in the inner cavity of the second rack 15 is fixedly mounted on the outer wall of the feeding rod 9. A second spring 17 is fixedly connected to one side wall of the sliding block 16. The second spring 17 is sleeved on the feeding rod 9 and is fixedly connected to the other end of the second rack 15 and the inner wall of the sliding cavity.

[0029] It should be understood that the micro switch 6 is electrically connected to the industrial control computer of the machine tool. When part 10 is being fed, if there is jamming or debris causing the feeding to be incomplete, the second spring 17 on the feeding rod 9 is compressed, the micro switch contact 5 is displaced, and the output signal of the micro switch 6 is connected in parallel with the pause button circuit of the CNC lathe, commanding the equipment to pause and alarm, thus ensuring the reliability of production.
