Description

TECHNICAL FIELD

[0001] The application relates to a butterfly nut machining device and method. BACKGROUND

[0002] The butterfly nut is a kind of nut, which is shaped like a butterfly. According to the process, the butterfly nut can be divided into cold heading butterfly nut, cast butterfly nut and stamping butterfly nut. According to the shape, the butterfly nut can be divided into two basic shapes of square wing and round wing. The butterfly nut has double wings, which can be manually tightened or loosened during use without the need to carry tools, so the application range is very wide.

[0003] As shown in the butterfly nut shown in Figure 1 The butterfly nut includes a cylindrical part 100 and a side plate part 200 connected to each other. A through hole 300 is provided through the cylindrical part. An internal thread needs to be milled on the inner wall of the through hole, and the outer wall of the side plate part needs to be milled. Generally, a CNC lathe is used for machining. The CNC lathe is a precision machining equipment controlled by a computer. It is an automatic machining equipment developed on the basis of a general milling machine. The main work of CNC machining is to program and automatically control the machining route.

[0004] During the machining process, the position of the butterfly nut needs to be fixed to ensure the quality and aesthetics of the product. At present, the fixing of the butterfly nut in the field of mechanical machining usually adopts a manual clamp or a general mechanical clamp. Although the manual clamp has a simple structure, its efficiency is low and the positioning accuracy is greatly affected by human factors.

[0005] The main methods of fixing the butterfly nut by the general mechanical clamp include: ① three-jaw chuck clamping: the nut outer edge is clamped by the radial clamping jaw, but it is easy to cause deformation of the thin-walled butterfly nut; ② magnetic clamp adsorption: the nut bottom surface is fixed by magnetic force, but the lateral displacement cannot be limited, and vibration is easy to occur during milling; ③ hydraulic expansion mandrel: the mandrel is inserted into the nut inner hole and then expanded by hydraulic pressure, but it is only suitable for inner hole machining and cannot be used for outer edge milling.

[0006] The main defects of the prior art are: ① uneven clamping force distribution causes local deformation of the butterfly nut; ② unstable lateral positioning causes milling vibration, affecting the thread machining accuracy; ③ the clamp structure is complex, and it takes a long time to adjust when replacing the workpiece, which is difficult to meet the batch production demand.

[0007] In view of the above-mentioned related technologies, the existing clamp cannot well clamp the butterfly nut during the machining process of the butterfly nut, which may affect the quality of the product, and therefore needs to be improved. SUMMARY
