Description

Technical Field

[0001] This utility model relates to the field of CNC grinding machine technology, specifically to an automatic feeding mechanism for a five-axis CNC grinding machine. Background Technology

[0002] Five-axis CNC grinding machines are operated using computer numerical control technology. They automatically execute complex machining tasks through pre-programmed instructions. These machines are typically equipped with multiple grinding heads and various grinding tools, which can be flexibly adjusted according to different machining needs. Five-axis CNC grinding machines include a machining mechanism and a loading mechanism. The loading mechanism typically includes a long cantilever, a short cantilever, a clamping cylinder, and a loading jaw, etc.

[0003] According to the existing technical field publication CN216327537U, an automatic loading mechanism for a five-axis CNC grinding machine is disclosed. This mechanism uses a clamping cylinder to drive the loading jaws to grip the workpiece, then a rotary cylinder rotates the turntable, which in turn rotates the long cantilever via an L-shaped cantilever, and then the short cantilever rotates the loading jaws to move the workpiece to the appropriate position. Finally, the clamping cylinder drives the loading jaws to release the workpiece, completing the loading action. However, this device has a small gripping contact area with the workpiece. When the workpiece surface is smooth and cylindrical, the loading jaws may not be able to hold the workpiece stably, causing it to fall during loading. This results in poor reliability of the automatic loading mechanism and reduced work efficiency. Therefore, to address these problems, we propose an automatic loading mechanism for a five-axis CNC grinding machine. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic feeding mechanism for a five-axis CNC grinding machine, in order to solve the problem that when the device has a small gripping contact area with the workpiece, and the workpiece surface is smooth and cylindrical, the feeding jaws may be unstable in gripping the workpiece, causing the workpiece to fall during the feeding process, resulting in poor reliability of the automatic feeding mechanism and reduced work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Clamping cylinders are fixedly connected to the inner sides of both the left and right ends of the fixing frame. A connecting plate is fixedly connected to the other end of the clamping cylinder. A second compression spring is fixedly connected to the side of the connecting plate away from the clamping cylinder. A clamping plate is fixedly connected to the other end of the second compression spring. A damping pad is fixedly connected to the side of the clamping plate away from the second compression spring.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, by setting up a suction fan, a connecting pipe, a suction cup, a first compression spring, a clamping block, a clamping plate, and a damping pad, when the workpiece surface is smooth and cylindrical, the suction fan is activated. The suction fan, through the connecting pipe and the suction cup, sucks up and fixes the upper surface of the workpiece.
