[0002] Spring machines generally refer to spring coiling 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.

[0003] The tool holder of a spring machine will reciprocate and extend when working, thereby driving the tool to move. However, the existing telescopic structure of the tool holder of a spring machine has shortcomings when in use. Due to its own inertia, the tool holder needs to overcome the speed brought by the inertia when moving in the reverse direction at the reciprocating turning position. This will make the connection position between the tool holder and the telescopic structure susceptible to a large pulling force, which greatly reduces the service life of the telescopic structure. To this end, a telescopic structure for a spring machine tool holder is proposed. Utility Model Content

[0021] When in use, the tool holder seat 4 is controlled to reciprocate and extend in the slide groove 10 through the telescopic mechanism, and buffer plates 12 are respectively arranged at the turning positions at both ends of the tool holder seat 4, which can buffer the tool holder seat 4 when it moves to the end, overcome the impact force caused by the inertia of the tool holder seat 4, and make the tool holder seat 4 more stable when turning. At the same time, the buffer spring 13 between the buffer plate 12 and the inner wall of the slide groove 10 can cache the kinetic energy brought by the inertia of the tool holder seat 4. When the tool holder seat 4 moves in the opposite direction, the buffer spring 13 restores the deformation to provide a certain amount of assistance to the tool holder seat 4, relieves the pulling force that the connection position between the tool holder seat 4 and the telescopic mechanism has to bear, thereby improving the service life of the device.

[0022] The telescopic mechanism includes a rotating disk 2 and a connecting plate 8. The rotating disk 2 is rotatably connected to the upper end of the mounting plate 1. The bottom of the rotating disk 2 is connected to a driving assembly. The upper surface of the rotating disk 2 is rotatably connected to a rotating member 5 away from the center position. A connecting rod 6 is fixedly connected to the side wall of the rotating member 5. The end of the connecting rod 6 is fixedly connected to a U-shaped frame 7. A rotating column 14 is fixedly connected between two parallel plates of the U-shaped frame 7. The connecting plate 8 is fixedly connected to the side wall of the tool holder seat 4.

Buffer plates 12 are respectively arranged at the turning positions at both ends of the tool holder seat 4, which can buffer the tool holder seat 4 when it moves to the end, overcome the impact force brought by the inertia of the tool holder seat 4, and make the tool holder seat 4 more stable when turning. At the same time, the buffer spring 13 between the buffer plate 12 and the inner wall of the slide groove 10 can cache the kinetic energy brought by the inertia of the tool holder seat 4.
