The technical scheme of the utility model is that:
the utility model provides a pin structure is taken out in smart location which characterized in that: it includes hydro-cylinder shell and positioning seat, the inside of hydro-cylinder shell is provided with the slip chamber, the top of hydro-cylinder shell just is located the slip intracavity and is provided with the guide holder, the inside slidable mounting of guide holder has the piston rod, the top fixedly connected with connecting rod of piston rod, the top of hydro-cylinder shell is provided with the positioning seat, the inside slidable mounting of positioning seat has the locating lever, the spring is installed to the bottom of locating lever, the connecting rod stretch into in the positioning seat and with spring coupling.
Further, a sealing ring is fixedly arranged between the outer side of the bottom of the piston rod and the inner wall of the oil cylinder shell; through being equipped with the sealing washer, can effectively improve the inside sealing performance of hydro-cylinder.
Furthermore, an exhaust groove is formed in one side of the bottom of the positioning rod.
Furthermore, the bottom of the positioning seat is close to one side of the exhaust groove and is provided with an air vent corresponding to the exhaust groove, and the exhaust groove is communicated with the air vent; when the air vent ventilates with the air discharge duct, reach the value, give model mechanical equipment can not the processing state at present, be plugged up by the locating lever when the air vent and form atmospheric pressure and rise, reach the value, give model mechanical equipment processing state at present.
Furthermore, a limiting screw is installed at the bottom of the positioning rod, and the other end of the limiting screw is communicated with the positioning seat.
Furthermore, the connecting rod and the spring are connected by welding.
Furthermore, the positioning seat and the oil cylinder shell are made of high-strength aluminum alloy.
The utility model discloses a theory of operation does: when the positioning device works, the positioning pin is inserted into the positioning hole; when the positioning hole needs to be machined, the positioning rod is pressed downwards, at the moment, the vent hole is blocked by the positioning rod to form air pressure rise, a numerical value can be reached, and the model mechanical equipment can be machined at present; when needs are fixed a position the locating hole, have the function of floating through the spring action, the locating lever rises, and at this moment, the air vent is ventilated with the air discharge duct, reaches but numerical value, gives model mechanical equipment can not the processing state at present.
The utility model has the advantages that: the utility model discloses simple structure, the practicality is strong, install the spring through the bottom at the locating lever, utilize the elasticity of spring, can raise the locating lever, carry out accurate location to the locating hole, in addition, through be provided with air discharge duct and air vent on locating lever and positioning seat, when the locating lever pushes down, it rises to form atmospheric pressure after plugging up the air vent, the locating lever of fixing one's residence, can process to the locating hole, can enough carry out accurate location to the locating hole, can give the performance that the processing cutter carried out processing to the locating hole in the location again.
