Description

Technical Field

[0001] The utility model belongs to the technical field of CNC machining, and particularly relates to a material taking mechanism for CNC machining equipment. Background Technique

[0002] CNC machining generally refers to computer numerical control precision machining, including CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines, etc. During the CNC machining process, a material taking mechanism is required to transport the processing raw materials into the CNC machining equipment.

[0003] A Chinese patent application with the publication number CN216657242U discloses an automatic material taking device for a CNC, including a bottom plate and mounting holes. A first motor is fixedly connected to one side of the bottom plate, a lead screw is arranged on one side of the first motor, and a moving plate is threadedly connected to the outer surface of the lead screw. The advantages of this utility model are as follows: The first motor drives the lead screw to rotate, so that the moving plate slides and lifts on the outer surface of the guide rod to adjust the height of the rotating plate. The second motor drives the rotating rod to rotate to adjust the position of the rotating plate. When taking materials, the cylinder drives the connecting plate to move, so that the anti-slip pad contacts the workpiece, and the anti-slip pad drives the sliding rod to slide. Through the telescopic elasticity of the spring, the clamping force is buffered to a certain extent, avoiding damage to the workpiece, ensuring that CNC machining does not require manual material taking by workers, avoiding reduction of processing efficiency, and avoiding increase of the working intensity of workers.

[0004] However, this patent has the problem that the clamping and fixing of the workpiece is not firm enough. When clamping and taking materials for annular and cylindrical workpieces, the contact area between the two anti-slip pads and the workpiece is small. When the workpiece is heavy, the workpiece is likely to slip off, resulting in the workpiece falling, which not only increases the danger but also may damage the CNC machining equipment. Therefore, we provide a material taking mechanism for CNC machining equipment to solve the above problems. Summary of the Utility Model
