[0003] The current feeding mechanisms for CNC machining centers, such as the one proposed in publication number CN220533645U, have multiple material slots on the upper shell to simultaneously place multiple workpieces, and cooperate with the bidirectional threaded rod, the slider and the clamping block to clamp or loosen the workpieces inside the material slots. The servo motor, the first gear and the second gear adjust the position of the material slots. By cooperating with each other, the workpieces can be clamped in batches and continuously processed in cooperation with CNC machining equipment, thereby reducing the standby time of the CNC machining equipment and improving the machining efficiency.

It is impossible to keep the equipment working while replacing the workpieces, which is inconvenient to use. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example:

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a feeding mechanism for a CNC machining center, comprising a base 1, a CNC machining device 2 is installed on the top of one side of the base 1, and a lifting frame 3 is vertically arranged on the CNC machining device 2, wherein,

[0023] A processing head 4 is installed at the bottom of the lifting frame 3 away from the CNC processing equipment 2, and a rotating disk 5 is rotatably connected to the top of the other side of the base 1. The rotating disk 5 is driven to rotate by an electric mechanism. The tops of the four sides of the rotating disk 5 close to the side are symmetrically fixedly connected to the first bracket 10, and the rotating disk 5 is fixedly connected to the top of the first bracket 10 corresponding to the second bracket 11. A first clamping plate 12 is arranged on the inner side of the first bracket 10, and a second clamping plate 13 is arranged on the inner side of the second bracket 11;

[0024] The base 1 is fixedly connected with a transmission frame 14 near the top of the CNC processing equipment 2, a guide rod groove 15 runs through the middle of the first bracket 10, a guide rod 16 is fixedly connected to the first clamping plate 12 on the side corresponding to the guide rod groove 15, a baffle 17 is fixedly connected to the guide rod 16 near the outer side of the first bracket 10, a spring 18 is sleeved on the guide rod 16 between the baffle 17 and the first bracket 10, first guide grooves 19 are symmetrically opened on both sides of the first bracket 10, and a first guide rod 20 is fixedly connected to the first clamping plate 12 at a position corresponding to the first guide groove 19;

[0025] When loading is needed, the rotating disk 5 is driven by the electric mechanism to rotate, and the rotating disk 5 drives the clamping structures arranged on the four sides of the top plate to rotate cyclically. When the rotating disk 5 drives the clamping structure to move to the opposite side of the CNC processing equipment 2, the workpiece between the first clamping plate 12 and the second clamping plate 13 is replaced, the processed workpiece is taken down, and the workpiece to be processed is placed. After the workpiece directly under the CNC processing equipment 2 is processed, the rotating disk 5 continues to rotate, and when the guide rod 16 is against the transmission frame 14, the transmission frame 14 enables the guide rod 16 to overcome the elastic force of the spring 18 to drive the first clamping plate 12 to move toward the second clamping plate 13, clamp and fix the workpiece to be processed, so that the workpiece to be processed is moved to the underside of the CNC processing equipment 2, and the processed workpiece is moved to the opposite side of the CNC processing equipment 2, and the workpiece is replaced. Through this loading mechanism, the CNC processing equipment 2 can continue to work and process the workpiece while taking and placing the workpiece, thereby effectively improving the processing efficiency of the CNC processing equipment 2.

[0026] See also Figures 1 to 3 The electric mechanism includes a rotating shaft 6, and the rotating disk 5 is rotatably connected to the base 1 through the rotating shaft 6.

The transmission frame 14 is annular, and the center of the transmission frame 14 coincides with the center of the rotating disk 5, and both ends of the transmission frame 14 are inclined surfaces. When it is necessary to control the rotation of the rotating disk 5, the stepper motor 8 drives the worm 9 to rotate, and the worm 9 drives the rotating shaft 6 to rotate by meshing with the worm gear 7, so that the rotating shaft 6 drives the rotating disk 5 to rotate. Through the electric mechanism, the rotation of the rotating disk 5 is conveniently controlled.

Second guide grooves 22 are symmetrically provided on both sides of the second bracket 11, and a second guide rod 23 is fixedly connected to one side of the second clamping plate 13 corresponding to the second guide groove 22. The moving distance of the first clamping plate 12 is fixed when clamping. When the size of the workpiece changes, by rotating the adjusting screw 21, the adjusting screw 21 drives the second clamping plate 13 to move through the threaded connection formed with the second bracket 11, and the second clamping plate 13 moves linearly through the second guide groove 22 and the second guide rod 23, so that the initial spacing between the second clamping plate 13 and the first clamping plate 12 can be adjusted, and the position of the second clamping plate 13 can be adjusted to facilitate quick fixing of workpieces of different sizes.

[0028] Working principle: This kind of feeding mechanism for CNC machining center, when it needs to load materials, drives the rotating disk 5 to rotate through the electric mechanism, and the rotating disk 5 drives the clamping structures arranged on the four sides of the top plate to rotate cyclically. When the rotating disk 5 drives the clamping structure to move to the opposite side of the CNC machining equipment 2, the workpiece between the first clamping plate 12 and the second clamping plate 13 is replaced, the processed workpiece is removed, and the workpiece to be processed is placed. After the workpiece directly under the CNC machining equipment 2 is processed, the rotating disk 5 continues to rotate, and when the guide rod 16 abuts against the transmission frame 14, the transmission frame 14 enables the guide rod 16 to overcome the elastic force of the spring 18 and drive the first clamping plate 12 to move toward the second clamping plate 13, clamping and fixing the workpiece to be processed, so that the workpiece to be processed is moved to the right below the CNC machining equipment 2, and after the processed workpiece is moved to the right opposite side of the CNC machining equipment 2, the workpiece is replaced. Through this feeding mechanism, the CNC machining equipment 2 can continue to work and process the workpiece while taking and placing the workpiece, thereby effectively improving the processing efficiency of the CNC machining equipment 2.

[0029] When it is necessary to control the rotation of the rotating disk 5, the stepper motor 8 drives the worm 9 to rotate, and the worm 9 drives the rotating shaft 6 to rotate by meshing with the worm wheel 7, so that the rotating shaft 6 drives the rotating disk 5 to rotate. Through the electric mechanism, it is convenient to control the rotation of the rotating disk 5, and the moving distance of the first clamping plate 12 is fixed when clamping. When the size of the workpiece changes, by rotating the adjusting screw 21, the adjusting screw 21 drives the second clamping plate 13 to move through the threaded connection formed with the second bracket 11. The second clamping plate 13 moves linearly through the second guide groove 22 and the second guide rod 23, so that the initial spacing between the second clamping plate 13 and the first clamping plate 12 can be adjusted. By adjusting the position of the second clamping plate 13, it is convenient to quickly fix workpieces of different sizes.
