Abstract

The invention relates to a locating mechanism, in particular to a spring pin telescoping mechanism used in the machining process of blank location holes. The spring pin telescoping mechanism comprises a fixture plate. A guide holder is fixed to the upper portion of the fixture plate, and a linear cylinder is fixed to the bottom of the fixture plate. A piston rod of the linear cylinder penetrates out of the fixture plate and extends into a guide hole of the guide holder. A pull rod is connected to the end of the piston rod, a locating sleeve is fixed in the guide hole, and the pull rod is fixedly connected to an inner hole of the locating sleeve through a transversely-arranged round pin. A spring pin is arranged in the locating sleeve, a spring is arranged in a counter bore in the bottom of a locating pin, the bottom end of the spring abuts against an adjusting screw tightly, and the adjusting screw is arranged in the locating sleeve in a screwed mode and corresponds to the upper portion of the round pin. The spring pin telescoping mechanism is simple and reasonable in structure; through additional arrangement of the linear cylinder, the linear cylinder can be used for pulling down the spring pin when the spring pin needs to avoid a tool, and therefore the tool can be avoided.

Description

technical field [0001] The invention relates to a positioning mechanism, in particular to an elastic pin telescopic mechanism used in the process of machining positioning holes of blanks. Background technique [0002] In the design of machining fixtures, it is often encountered that the inner hole blank is positioned, but the positioning hole needs to be processed, and the traditional elastic pin structure cannot be stretched to avoid the tool. Contents of the invention [0003] Aiming at the above problems, the present invention provides an elastic pin telescopic mechanism, which can effectively realize the elastic pin avoiding the tool. [0004] According to the technical solution of the present invention: an elastic pin telescopic mechanism is characterized in that: it includes a clamp plate, a guide seat is fixed on the top of the clamp plate, a linear cylinder is fixed on the bottom of the clamp plate, and the piston rod of the linear cylinder moves from the clamp pla...
