Description

Technical Field

[0001] The utility model relates to the technical field of clamping mechanisms, in particular to a coil spring clamping mechanism. Background Art

[0002] Spring coiling machines are commonly known as spring machines, which generally refer to mechanical equipment for producing springs. According to their functional characteristics, they are divided into compression spring machines, tension spring machines, universal machines, disc machines, and special spring machines such as snake spring machines and torsion spring machines. According to the driving mode, they are divided into semi-automatic, automatic, and CNC types. During the processing, the spring coiling machine needs to use a clamping mechanism to clamp the parts to the appropriate position for processing.

[0003] The existing coil spring clamping device directly clamps the coil spring parts during use. Since the surface of the coil spring is usually very smooth, this smooth surface characteristic makes it easy for the coil spring to change position around the clamping contact point during the clamping process, which will cause the subsequent transmission position to be inaccurate. In the processing process, accurate position transmission is crucial because it directly affects the subsequent processing effect. If the position transmission is inaccurate, the subsequent processing effect will be affected, which may lead to a decline in product quality and even waste, greatly reducing the practicability of the clamping equipment, which needs to be optimized and improved.
