The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Fig. 1, Fig. 2 illustrate an embodiment of the invention.Pneumatic Control Stepless Indexing Mechanism of the present invention comprises the driving shaft that drives indexing means, the indexing mechanism that is connected with driving shaft and the calibration output shaft that is connected with indexing mechanism.Described indexing means is driven by oscillating cylinder 1, and the adjustment of the scale division value of indexing means promptly is that the pendulum angle of adjusting oscillating cylinder 1 realizes that pendulum angle can be adjusted, so the adjusting range of the scale division value of its indexing means is bigger in 0～180 ° of scope.The rear end of described oscillating cylinder 1 connects a driving shaft 4, and the rear end of described driving shaft 4 connects one division output shaft 7, and the installation fixed head 14 of a band spindle drum 15 is set between described oscillating cylinder 1 and the described driving shaft 4.
Described driving shaft 4 is set to also its front end band one endoporus 4 of ladder cylindricality, one single roll bearing 3 is set in the described driving shaft endoporus 41, the ladder cylindricality of described driving shaft 4 middle part is provided with a single roll bearing 5, between the interior ring 51 of described single roll bearing 5 and the described driving shaft 4 key 18 is set and fixedlys connected.Described single roll bearing 3, single roll bearing 5 can guarantee that processed workpiece only does unidirectional rotation.Unilateral bearing 3 in the described driving shaft front end endoporus is oppositely to install with the unilateral bearing 5 at the ladder cylindricality middle part of described driving shaft.
Being connected between the rear end of described driving shaft 4 and the calibration output shaft 7 by freewheel clutch 6, described freewheel clutch is the double rolling key clutch with power shaft and driven shaft, and the power shaft of described freewheel clutch and driven shaft are to be fixed by the jump ring 16 and 17 at its two ends, left and right sides with respect to the axial location of described driving shaft 4 and described output shaft 7.The packing ring 11 of one adjusting axial location is set between described freewheel clutch 6 and the described rolling bearing 5; The effect of described freewheel clutch 6 is as non-return mechanism, and the power and the motion of its power shaft passed to driven shaft, and driven shaft is subjected to external force to do the time spent can not to rotate.When described calibration output shaft 7 was subjected to extraneous excess load moment loading, freewheel clutch promptly was in released state, to guarantee the reliability of its work.
The middle part of described calibration output shaft 7 is provided with an axial shoulder 71, described shoulder 71 an axial antifriction bearing 8 each side is set, to improve the axially-movable precision of calibration output shaft 7; The packing ring 10 of one adjusting axial location is set between described rolling bearing 8 and the described freewheel clutch 6.The end of described calibration output shaft 7 is fixedly mounting by the workpiece 16 of calibration.
One sleeve 12 is set in the endoporus of described spindle drum 15, and described driving shaft 4, calibration output shaft 7 and freewheel clutch 6 are fixed in the described sleeve 12 by locking nut 9,13 respectively, and its compact conformation, outward appearance are succinct.
Described oscillating cylinder 1 is the compressed air-driven that is provided by pipeline 12.Described oscillating cylinder 1 is provided with one and is used for controlling its drive actions magnetic valve (figure does not illustrate), a programmable controller (figure does not illustrate) that is used for controlling the blanking time of its calibration is set, to realize the automatic control of calibration action again.
Dividing movement is achieved in that the terminal hard-wired workpiece 16 by calibration of setting described calibration output shaft 7 earlier is rotations counterclockwise.Oscillating cylinder 1 as driver part is done rotation counterclockwise, then the axle sleeve 2 that is connected with the output shaft head 11 of described oscillating cylinder rotates, this moment, described single roll bearing 3 did not rotate, drive described driving shaft 4 rotations by described single roll bearing 3 then, drive interior ring 51 rotations of the single roll bearing 5 of fixedlying connected again with key 18, described driving shaft 4 drives the power shaft rotation of the described freewheel clutch 6 of fixedlying connected with key 19 again, and the driven shaft of described freewheel clutch 6 also rotates thereupon synchronously.Since this moment described freewheel clutch 6 power shaft and the driven shaft state that is set to be connected, so also rotation synchronously thereupon of the described calibration output shaft 7 of fixedlying connected with key 19.
When described oscillating cylinder 1 resetted, this moment, described single roll bearing 3 rotated, and the interior ring 51 of described single roll bearing does not rotate, so main shaft 4 does not rotate yet; Thereby described calibration output shaft 7 does not rotate yet.So just finish a calibration action.The instruction of blanking time by described its calibration of programmable controller editor realizes that described oscillating cylinder rotates the overall process calibration function that realizes Pneumatic Control Stepless Indexing Mechanism of the present invention continuously.
