For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] Please refer to Figure 1 and Figure 2 , a feeding device for a CNC machine tool, including a fixed column 10 and a pushing assembly 20 installed on the fixed column 10 for clamping and pushing the workpiece to be processed; wherein, the pushing assembly 20 includes a connecting seat 201, a clamping ring 202 installed on the side of the connecting seat 201, a first driving unit installed in the connecting seat 201 and connected to the clamping ring 202 for driving the clamping ring 202 to rotate relative to the connecting seat 201, a clamping unit installed around the clamping ring 202 for clamping and fixing the workpiece to be processed located inside the clamping ring 202, and a flipping driving unit connected to the connecting seat 201 for driving the connecting seat 201 to flip.

[0022] In this embodiment, during operation, the workpiece to be processed is located inside the clamping ring 202. At this time, the clamping unit clamps and fixes the workpiece to be processed; but when the placement angle of the workpiece needs to be adjusted, the first driving unit drives the clamping ring 202 to rotate, thereby driving the workpiece to be processed to rotate; when the workpiece to be processed needs to be flipped, the flipping driving unit works to drive the connecting seat 201 to flip, thereby flipping the workpiece to be processed.

[0023] A loading device for a CNC machine tool according to the present utility model, through the arrangement of the fixing column 10 and the pushing component 20, can effectively rotate and turn the workpiece to be processed, greatly meeting the process requirements and improving the user experience.

Specifically, during operation, the first cylinder 206 drives the clamping plate 207 to clamp and release the workpiece to be processed; in addition, since the upper end surface of the arc-shaped connecting block 205 is higher than the upper end surface of the connecting seat 201, it prevents the first cylinder 206 from interfering with the connecting seat 201 when the clamping ring 202 rotates.

[0026] In a specific embodiment, the turning driving unit includes a rotary cylinder 208 connected to the connecting seat 201.
