Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
High-precision rotary cylinder, as shown in Figure 1-2, gear shaft 5 is installed in the central position of cylinder body 1 to structure, and gear shaft 5 upper end, lower end have installed clutch shaft bearing 14, second bearing 16 of high-precision rotary respectively, ensures the running accuracy of gear shaft 5.Dust ring 13 has been installed in the upper end of gear shaft 5, thus it is inner to prevent dust and other impurity from entering gear shaft 5.Locking nut 17 is installed in the bottom of gear shaft 5, ensures that gear shaft 5 can not move on axial position.Gear shaft 5 is connected with tooth bar 10, and the rotation of gear shaft 5 is realized by the to-and-fro motion of tooth bar 10, and the to-and-fro motion of tooth bar 10 carries out transmission by the inlet hole ventilation be arranged on cylinder body 1 to tooth bar 10.Tooth bar 10 two ends are threaded connection hydraulic bjuffer 12, and hydraulic bjuffer 12 plays the buffer function to tooth bar 10.The end of tooth bar 10 arranges tooth bar end cap 11, tooth bar end cap 11 by screw-threaded coupling on cylinder body 1.When tooth bar 10 moves to end time, tooth bar end cap 11 makes tooth bar 10 motion stop.Inside cylinder body 1, by gear shaft 5, arrange lock pin 8, the central axis of lock pin 8 passes through the central axis of gear shaft 5, and lock pin 8 pairs of gear shafts 5 carry out locked action.Lock pin 8 is connected by screw piston 4, piston 4 has been installed the second piston packing 3, has played seal action.Lock pin 8 end is provided with lock pin end cap 6, and piston 4 stops back to lock pin end cap 6 place, and lock pin end cap 6 passing hole back-up ring 7 is fixed.Cylinder body 1 has installed stop pin 15, and stop pin 15 prevents lock pin 8 from rotating.When air inlet, gas push piston 4 moves, thus realizes the locked motion of lock pin 8 pairs of gear shafts 5.First piston seal ring 2 arranges on the rack gear 10, sealing tooth bar 10.O RunddichtringO 9 is arranged on tooth bar end cap 11.
The working procedure of high-precision rotary cylinder is: tooth bar 10 is in the process of inflation, and tooth bar 10 moves to the other end from one end, and now, tooth bar 10 driven gear axle 5 rotates.When tooth bar end cap 11 encountered by tooth bar 10 time, tooth bar 10 stop motion, gear shaft 5 also stops the rotation simultaneously.But gear shaft now 5 angle of swing is inaccurate.Inflate then to piston 4, lock pin 8 carries out straight line motion and is inserted on the flank of tooth of gear shaft 5, corrects the error that gear shaft 5 rotates, thus obtains accurate 90 ° of angle of swing.It is more than a do action.When reverse 90 ° time, be first that piston 4 is inflated, allow it return to lock pin end cap 6 place.Now again tooth bar 10 is inflated, tooth bar 10 moves to another one position from a position, driven gear axle 4 turns round, when tooth bar 10 stops at tooth bar end cap 11 place time, gear shaft 5 also stop motion, at this moment inflate the piston 4 of lock pin, at this moment piston 4 is inserted on the flank of tooth of gear shaft 5, and at this moment gear shaft 5 reverses 90 ° again accurately.This completes an overall motion cycle.
