Description

Technical Field

[0001] This utility model relates to the field of feeding mechanisms, and in particular to a feeding mechanism for CNC machining centers. Background Technology

[0002] The feeding mechanism for CNC machining centers is a feeding mechanism that conveys and places materials during the processing of materials by CNC machining centers. It can replace manual material placement, increase processing efficiency, and is widely used in CNC machining centers.

[0003] However, when using clamping structures, current common feeding mechanisms can usually only achieve simple linear material conveying or single-directional positioning, resulting in poor flexibility and adaptability. When processing workpieces requiring multi-angle machining or irregular shapes, the machining process often needs to be interrupted, and operators must manually adjust the angle and posture of the material, or use other auxiliary equipment for secondary positioning. This manual intervention not only significantly reduces production efficiency and increases labor intensity, but also affects the final machining accuracy due to human positioning errors, even leading to an increase in scrap rate. In addition, some existing automated feeding mechanisms are insufficient in terms of motion stability. For example, during lifting or lateral movement, traditional chain or gear transmissions are prone to vibration and impact, which may cause slight displacement or loosening of the clamped material. This is unacceptable for high-precision machining scenarios. At the same time, the functional modules of most mechanisms are independent and have low integration, resulting in a complex system structure, large space occupation, and low collaborative work efficiency. Utility Model Content

[0004] The main objective of this invention is to provide a feeding mechanism for CNC machining centers, which can effectively solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A feeding mechanism for a CNC machining center includes a mounting plate, a rotating base, a movable lead screw, a movable motor, and a lead screw sleeve. The rotating base is fixedly mounted on the lower end of the mounting plate. The movable lead screw is movably mounted on the front end of the mounting plate. The movable motor is fixedly mounted on one side of the mounting plate. The lead screw sleeve is threaded onto the outer side of the movable lead screw. A mounting panel is fixedly mounted on the front end of the lead screw sleeve. A lifting motor is fixedly mounted on the rear end of the mounting panel. A first pulley and a second pulley are fixedly mounted on the front end of the mounting panel, with the first pulley positioned above the second pulley. A lifting belt is movably mounted on the outer side of the first and second pulleys. A clamping structure is fixedly mounted on one side of the first and second pulleys at the front end of the mounting panel.

[0007] As a further embodiment of this utility model, the rotating shaft of the mobile motor passes through one side of the mounting plate and is fixedly connected to the moving lead screw, and the mounting panel is located in front of the mounting plate.

[0008] As a further embodiment of this utility model, a guide rail is fixedly installed at the front end of the mounting platform at the lower end of the moving lead screw, and a moving slider is slidably installed on the outer side of the guide rail, with the mounting panel fixedly installed at the front end of the moving slider.

[0009] As a further embodiment of this utility model, the shaft of the lifting motor passes through the mounting panel and is fixedly connected to the first pulley, and the first pulley and the second pulley rotate synchronously through the lifting belt.

[0010] As a further embodiment of this utility model, the clamping structure includes a lifting guide plate, a lifting mounting plate, a rotary motor, a clamping cylinder, and a clamping plate. The lifting guide plate is fixedly installed at the front end of the mounting panel, and the lifting mounting plate is slidably installed on the outside of the lifting guide plate. The rotary motor is fixedly installed at the front end of the lifting mounting plate, the clamping cylinder is fixedly installed at the lower end of the rotating shaft of the rotary motor, and the clamping plate is fixedly installed at the lower end of the piston rod of the clamping cylinder.

[0011] As a further embodiment of this utility model, the lifting mounting plate moves up and down around the lifting guide plate, the lifting mounting plate is externally fixedly connected to the lifting belt, and the clamping plate is located in front of the mounting platform.

[0012] Compared with the prior art, the present invention has the following advantages: the clamping plate of the clamping structure accurately clamps the material through the clamping cylinder, and the rotary motor drives the clamping plate to rotate, which can adapt to the needs of different processing angles. The multi-angle material clamping and rotation function improves the placement accuracy and flexibility, which avoids the error of manual adjustment, and is especially suitable for complex CNC machining scenarios.

[0013] The lifting motor drives the lifting mounting plate to move up and down along the lifting guide plate via the first pulley, the second pulley, and the lifting belt, ensuring smooth vertical movement of the clamping structure and efficient lifting motion. The moving motor drives the moving lead screw to rotate, and the lead screw sleeve and the moving slider move left and right along the guide rail, realizing the lateral movement of the mounting panel and the clamping structure, improving the stability of material conveying, reducing material vibration, improving the reliability of the feeding process, automating lateral conveying, enhancing feeding efficiency, replacing manual handling, significantly shortening material placement time, and improving the overall efficiency of the CNC machining center. Furthermore, the rotating base supports the overall rotation of the mounting plate. Combining the above functions, the structure has a high degree of integration, a wide range of applications, and can handle materials of various sizes and shapes. Attached Figure Description

Figures 1-4 The assembly includes a mounting platform 1, a rotating base 2, a movable lead screw 3, a movable motor 4, and a lead screw sleeve 8. The rotating base 2 is fixedly installed at the lower end of the mounting platform 1. The movable lead screw 3 is movably installed at the front end of the mounting platform 1.

A clamping structure 13 is fixedly installed on the front end of the mounting panel 6 on one side of the first pulley 10 and the second pulley 11.

[0021] Please refer to this carefully. Figures 1-3 The rotating shaft of the moving motor 4 passes through one side of the mounting plate 1 and is fixedly connected to the moving lead screw 3. The mounting panel 6 is located in front of the mounting plate 1.

[0022] Please refer to this carefully. Figure 1 and Figure 3The front end of the mounting plate 1 is fixedly mounted with a guide rail 5 at the lower end of the moving lead screw 3. A movable slider 7 is slidably mounted on the outside of the guide rail 5. The mounting panel 6 is fixedly mounted on the front end of the movable slider 7.

[0023] Specifically, the operation of the mobile motor 4 drives the mobile lead screw 3 to rotate, and the mobile lead screw 3 then moves left and right through the threaded connection with the lead screw sleeve 8, thereby driving the mounting plate 1 to move left and right around the guide rail rod 5 via the mobile slider 7, achieving the effect of left and right lateral conveying during material feeding.

[0024] Please refer to this carefully. Figure 4 The shaft of the lifting motor 9 passes through the mounting panel 6 and is fixedly connected to the first pulley 10. The first pulley 10 and the second pulley 11 rotate synchronously through the lifting belt 12.

[0025] Specifically, the operation of the lifting motor 9 drives the first pulley 10 to rotate, and then the first pulley 10 drives the lifting belt 12 to move, so that the lifting belt 12 moves around the outside of the first pulley 10 and the second pulley 11.

[0026] Please refer to this carefully. Figure 4 The clamping structure 13 includes a lifting guide plate 14, a lifting mounting plate 15, a rotary motor 16, a clamping cylinder 17, and a clamping plate 18.

[0028] Specifically, the clamping plate 18 clamps the material, and the movement of the lifting belt 12 drives the lifting mounting plate 15 to move up and down around the lifting guide plate 14, thereby causing the clamping plate 18 to move up and down. The operation of the rotary motor 16 drives the clamping cylinder 17 to rotate, thereby causing the clamping plate 18 to rotate and move, thus feeding and placing the material at different angles.
