[0004] In the existing technology, when machining on a CNC lathe, it is necessary to load parts. However, due to the different shapes of the parts, the loading structure cannot adapt to the use of various parts, resulting in the parts not being accurately positioned during loading. Insufficient matching of the positioning surfaces often leads to initial posture deviation, affecting the machining accuracy. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that the initial posture deviation of parts is often caused by insufficient matching of positioning surfaces during loading due to the different shapes of the parts, which affects the processing accuracy. Therefore, an automatic feeding CNC lathe is proposed.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1-5As shown, this utility model provides an automatic feeding CNC lathe, including a CNC lathe body 1. A mounting plate 3 is fixedly connected to one side of the CNC lathe body 1. A switching mechanism 4 is mounted on one side of the mounting plate 3. Feeding mechanisms 2 are mounted at both ends of the top of the switching mechanism 4. The two feeding mechanisms 2 include a feeding frame 23. A fixing plate 27 is fixedly connected to the inner side of the feeding frame 23. A first electric push rod 24 is fixedly connected to one side of the fixing plate 27. One end of the first electric push rod 24 passes through the fixing plate 27 and is fixedly connected to a movable sleeve 25. A guide rail 22 is slidably connected to the middle of the movable sleeve 25. A second electric push rod 28 is fixedly connected to the top of the movable sleeve 25. One end of the second electric push rod 28 passes through the movable sleeve plate 25 and is fixedly connected to a pneumatic finger 26. The top end of the pneumatic finger 26 is fixedly connected to one end of the guide rail 22. A guide rod 21 is fixedly connected to the inner side of the feeding frame 23. The outer side of the guide rod 21 is slidably connected to the movable sleeve plate 25. A fixed plate 27 is fixedly connected to the outer side of the guide rod 21. A steering wheel 48 is fixedly connected to the outer side of the steering rod 44. A guide groove 47 is opened on one side of the steering wheel 48. A sliding rod 49 is slidably connected inside the guide groove 47. One end of the sliding rod 49 is rotatably connected to a fourth electric push rod 410. The other end of the fourth electric push rod 410 is rotatably connected to the outer side of the switching column 43.

[0025] Feeding mechanisms 2 are installed at both ends of the steering rod 44. The second electric push rod 28 drives the pneumatic finger 26 to move. The guide rail 22 slides in the middle of the moving sleeve 25, causing the pneumatic finger 26 to move linearly in the vertical direction. The first electric push rod 24 drives the moving sleeve 25 to move. The moving sleeve 25 slides outside the guide rod 21, causing the moving sleeve 25 to move linearly in the horizontal direction, thus adjusting the horizontal position of the pneumatic finger 26. The pneumatic finger 26 includes a cylinder, a guide rail, a transmission structure, and gripping fingers. The cylinder drives the transmission structure to work, adjusting the distance between the two gripping fingers. This allows for the gripping and fixing of parts. By adjusting the horizontal and vertical positions of the pneumatic fingers 26, the loading and unloading positions of the parts can be adjusted. This method is applicable to feeding different parts and improves the positioning accuracy of the parts. During loading and unloading, the fourth electric push rod 410 drives the sliding rod 49 to move. The sliding rod 49 slides inside the guide groove 47, driving the steering wheel 48 to move. One end of the steering wheel 48 drives the steering rod 44 to rotate, thereby deflecting the angle of the feeding frame 23. For irregularly shaped parts, the loading angle of the parts can be adjusted during loading to improve the accuracy of positioning inside the CNC lathe body 1.

[0026] Example 2: Figure 3 and Figure 5As shown, the switching mechanism 4 includes a steering rod 44, with both ends of the steering rod 44 fixedly connected to one side of the two feeding frames 23 respectively. A switching column 43 is rotatably connected to the middle of the steering rod 44, and a positioning seat 45 is rotatably connected to the bottom end of the switching column 43. The bottom of the positioning seat 45 is fixedly connected to one side of the mounting plate 3. A gear 46 is fixedly connected to the outside of the switching column 43. A rack 42 meshes with the outside of the gear 46. A moving block 411 is fixedly connected to one side of the rack 42. A third electric push rod 41 is fixedly connected to one end of the moving block 411. One side of the third electric push rod 41 is fixedly connected to the other side of the mounting plate 3. A guide frame 412 is fixedly connected to the other side of the mounting plate 3. The inner side of the guide frame 412 is fixedly connected to the outer side of the moving block 411.

[0027] The overall effect of this embodiment is that, after one set of feeding mechanisms 2 feeds the parts onto the CNC lathe body 1, and another set of feeding mechanisms 2 clamps the parts, the third electric push rod 41 drives the moving block 411 to move. The moving block 411 slides inside the guide frame 412, causing the moving block 411 to make linear motion. The movement of the moving block 411 can drive the rack 42 to move. The rack 42 meshes with the gear 46, causing the gear 46 to rotate. The switching column 43 rotates accordingly, switching the position of the two sets of feeding mechanisms 2. The parts loading and unloading operations can be performed simultaneously, improving the processing efficiency of the CNC lathe body 1 on the parts.

[0028] The device's operation and working principle are as follows: The pneumatic finger 26 grips and fixes the parts. The second electric push rod 28 drives the pneumatic finger 26 to move, making it move vertically. The first electric push rod 24 drives the moving sleeve 25 to move, adjusting the horizontal position of the pneumatic finger 26. By adjusting the horizontal and vertical positions of the pneumatic finger 26, different parts are fed. The fourth electric push rod 410 drives the sliding rod 49 to move, sliding inside the guide groove 47, which in turn drives the steering wheel 48 to move, deflecting the angle of the feeding frame 23 and adjusting the feeding angle. One feeding mechanism 2 feeds the parts onto the CNC lathe body 1. After the other feeding mechanism 2 clamps the parts, the third electric push rod 41 drives the moving block 411 to move, causing the rack 42 to move and the gear 46 to rotate. The switching column 43 rotates accordingly, switching the positions of the two feeding mechanisms 2. This allows for simultaneous parts loading and unloading operations.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
