Abstract

The invention relates to a positioning mechanism of a tool fixture, in particular to a gas dustproof damping-free retractable elastic positioning mechanism, and belongs to the technical field of positioning. The gas dustproof damping-free retractable elastic positioning mechanism comprises a positioning pin base. The positioning pin base is internally provided with a through hole. The through hole is internally connected with a positioning pin in a sliding mode. The bottom of the positioning pin base is provided with a spring base. The lower end of a spring is located in the spring base, and the upper end of the spring makes contact with the positioning pin. The gas dustproof damping-free retractable elastic positioning mechanism is reliable in structure, good in protective property and convenient to maintain. In the normal state, gas between a pin body and the pin base is blown out of an opening of the pin base, and the gas dustproof function is achieved. A gas film is generated between the pin body and the pin base, no mechanical damping motion exists, and the flexibility of movement of the elastic positioning pin is improved. The service life of the spring is prolonged because no damping exists, and the adjusting requirement for the spring force of the elastic positioning pin is low.

Description

technical field [0001] The invention relates to a positioning mechanism of a fixture, in particular to a gas dustproof and non-damping retractable elastic positioning mechanism, which belongs to the technical field of positioning. Background technique [0002] The elastic locating pin without gas damping is a kind of elastic locating pin whose spring chamber communicates with the outside atmosphere, so that there is no gas damping and flexible movement when the locating pin moves up and down. At present, the general positioning pin moves up and down, and there is a certain fit gap between the pin and the pin body. During the positioning process of the workpiece, dust, iron powder, cutting fluid, etc. will enter, which will affect the flexible movement of the positioning pin and take a long time. If it blows, it will blow and jam, which will affect the positioning of the workpiece. [0003] In practice, it is found that the dust-proof ring provided in the sliding hole at the...
