Specific implementation mode

The technique effect of the design of the present invention, concrete structure and generation is described further below with reference to attached drawing, with It is fully understood from the purpose of the present invention, feature and effect.

Referring to figs. 1 to Fig. 4, a kind of guiding mechanism of deep hole signal detection in place, including hydraulic cylinder and its piston 4, institute It states that guiding mechanism is cylindrical, there is the guide sleeve seat 2 extended radially through, 2 outer ring front of the guide sleeve seat is set with piston bush 5, rear sleeve is equipped with sealing block set 8;2 interior forward end of the guide sleeve seat is equipped with guide sleeve 1, and middle rear end is equipped with piston 4, described to lead To cylindroid helical-coil compression spring 3 is set between 2 jackshaft neck of block set and piston, 2 rear end of the guide sleeve seat is stretched out backward And axis elastic collar 9 is housed;The front end outer ring of the piston bush 5 is set with combination bearing 6 and rotation saddle successively from inside to outside The front end sleeve of seat 7, the rotary saddle 7 bores disk 10 equipped with front clamp, and the front clamp cone disk 10 can drive under external force Rotary saddle 7 is rotated in the outer ring of combination bearing 6.8 inner radial of sealing block set is provided with piston and stretches out air inlet in place 13, piston, which stretches out gas outlet 14, piston in place and retracts air inlet 15 and piston in place, retracts gas outlet 16 in place, after the piston Portion is equipped with groove 19, and when piston stretches out in place, conducting piston stretches out air inlet 13 in place to the groove 19 and piston stretches out in place Gas outlet 14, when piston is retracted in place, conducting piston retracts air inlet 15 and piston in place and retracts gas outlet 16 in place.

The hydraulic cylinder is built-in hydraulic cylinder, and 8 inner radial of sealing block set is provided with piston and stretches out oil inlet 11 and piston retract oil inlet 12, respectively the piston stretches out and retracts fuel feeding.

Piston is set to stretch out in use, leading to oil in piston stretching oil inlet 11, after stretching out in place, piston rear portion groove 19 will Piston is connected and stretches out the air inlet 13 of air inlet in place and piston stretching gas outlet 14 in place, stretches out air inlet 13 in place in piston Ventilation stretches out 14 end of gas outlet in place in piston and carries out gas circuit signal detection, to judge whether piston stretching is all on board. Start to process again, end to be processed, retracting oil inlet 12 in piston and lead to oil makes piston retract, after retracting in place, piston rear portion ditch The conducting piston of slot 19 retracts air inlet 15 and piston in place and retracts gas outlet 16 in place, retracts air inlet 15 in piston and ventilates, Whether the end progress piston that piston retracts gas outlet 16 retracts gas circuit signal detection in place, all arrived to judge that piston is retracted Position, process finishing.

The guiding mechanism that the deep hole detects in place can be together in series to be used for multistation, with reference to Fig. 5, is connected for four stations It uses, the piston of previous guiding mechanism stretches out gas outlet 14 in place and the piston of the latter guiding mechanism stretches out air inlet in place 13 are connected, and the piston of previous guiding mechanism retracts gas outlet 16 in place and the piston of the latter guiding mechanism retracts air inlet in place Mouth 15 is connected.The piston of least significant end guiding mechanism stretches out gas outlet 14 in place and is connected with to entirely reaching the progress of bit serial gas circuit Pressure switch 17, the piston of least significant end guiding mechanism are retracted gas outlet 16 in place and are connected with to entirely retracting in place for the stretching of detection The stretching being detected to bit serial gas circuit pressure switch 18 in place.

In use, after the piston of all guiding mechanisms all stretches out in place, piston stretches out gas circuit and all turns on, before most It holds the piston of guiding mechanism to stretch out air inlet 13 in place to ventilate, stretches out gas outlet 14 in place in the piston of least significant end guiding mechanism Gas circuit of entirely connecting is detected at pressure switch 17, judges whether all pistons all stretch out in place according to gas circuit signal. End to be processed, after the piston of all guiding mechanisms is all retracted in place, piston is retracted gas circuit and is all turned on, in front end Piston retracts the ventilation of air inlet 15 in place, is retracted at the pressure switch 18 of gas outlet 16 in place in the piston of least significant end guiding mechanism Gas circuit of entirely connecting is detected, judges whether all pistons are all retracted in place.

Technical scheme of the present invention has many advantages, such as that operation is easy to implement, signal detection reliability is high, guiding accuracy is high, Being suitable for each actuating signal detection on automatic production line needs reliable and stable occasion.

According to the introduction of the present embodiment, those skilled in the art are can be achieved completely in other scope of the present invention Technical solution.
