Abstract

The utility model discloses an elastic positioning conical pin, which comprises a first conical pin seat, a second conical pin seat, an elastic conical pin, a spring guide post and a spring. The first conical pin seat is provided with a second conical pin seat. There is an elastic conical pin in the second cone pin seat, and a spring guide post is arranged under the elastic conical pin, and the spring is sleeved on the elastic guide post. The positioning surface is provided with a positioning circular hole. The above-mentioned technical scheme is adopted to manufacture an elastic positioning conical pin with close fit and high positioning accuracy. The elastic positioning conical pin in the utility model is usually used in combination with the elastic rhombic pin (similar in structure), and is often used in the initial processing of the workpiece. Because the conical surface is always closely attached to the prefabricated hole of the workpiece and the positioning accuracy is high, it is often used to Pre-machined in the jig and works well.
