Described tripper comprises fixed mount 3, worm screw stop means, unlocks handwheel 5, with unlock the eccentric wheel 6 that coaxially arranges of handwheel; Described unblock handwheel is arranged on fixed mount; The described worm screw other end to be arranged in worm screw stop means and can freely to rotate; Described eccentric wheel can promote worm screw stop means and move back and forth up and down; Described worm screw fixed mount is connected with fixed mount by being arranged near Hooks coupling universal coupling and perpendicular to the rotating shaft 17 of worm screw;
Described fixed mount is fixed on by the equipment of level-off axle place.
Above-mentioned tripper also comprises optoelectronic switch 12 and anti-dazzling screen 16; Described optoelectronic switch is arranged on fixed mount, and described anti-dazzling screen is arranged on eccentric wheel; When eccentric projection is positioned at peak, anti-dazzling screen covers optoelectronic switch just.
Above-mentioned worm screw stop means comprises two columns being separately positioned on the worm screw left side and the right, the stage clip being arranged on worm screw top, is arranged on the following unblock stage clip of worm screw; The upper end of described two columns is fixed on fixed mount; Described eccentric wheel contacts with following unblock stage clip.
The ratio of gear of above-mentioned worm gear and worm screw is 1:200.
The invention has the advantages that:
(1) worm and gear forms the reducing gear of a big retarding ratio, and become small angle change after the large rotation of handwheel is delivered to worm gear, Adjustment precision is high.
(2) utilize the feature of the reverse self-locking of worm and gear, realize the hard locking of machinery, locking intensity is high, and good reliability, is applicable to the occasion of heavier loads.
(3) use the state of optoelectronic switch to locking and unblock to indicate, precision is higher and easy to use.
Accompanying drawing explanation
Fig. 1 is stereographic map of the present invention;
Fig. 2 is sectional view of the present invention;
Fig. 3 is locking state schematic diagram;
Fig. 4 is released state schematic diagram.
Reference numeral is as follows: 1-trimming hand wheel; 2-worm gear; 3-fixed mount; 4-worm screw fixed mount, 5-unlocks handwheel; 6-eccentric wheel; 7-bearing; 8-finely tunes spindle; 9-ball head; 10-worm screw; 11-Hooks coupling universal coupling; 12-optoelectronic switch; 14-stage clip; 15-unlocks stage clip; 16-anti-dazzling screen.
Embodiment
As shown in Figure 1, 2, the present invention is formed primarily of trimming hand wheel 1, hitch bar, locking device and tripper.Hitch bar is used for transmitting main movement, and transverse axis is connected by flat key with worm gear 2.The ratio of gear of worm and gear is 1:200, worm screw 10 one end is connected with eccentric wheel tripper by stage clip, worm screw swings up and down around fixed rotating shaft, engage with worm gear after the height point jack-up of eccentric wheel 6, the worm screw other end is connected with the fine setting spindle 8 of WidFin handwheel by a Hooks coupling universal coupling 11.Because eccentric wheel and worm screw rotating shaft are all fixed pivots, rigidity of support is very high, this mechanism is had and firmly locks characteristic, lock safe and reliable.Eccentric below is equipped with the state of optoelectronic switch 12 to locking and unblock and is indicated.
First worm gear and worm screw are in non-engagement state, and rotate and unlock handwheel 5, the eccentric wheel be attached thereto rotates thereupon, and eccentric high some part, by worm screw upwards jack-up thus engage with worm gear, disconnects Electronic control circuit simultaneously.There is after worm and gear engagement the feature of reverse self-locking, realize the pitching locking of horizontal shafting.When not needing to finely tune, due to the engagement of worm and gear, worm gear is in self-locking state, is now locking state, and engagement locking state as shown in Figure 3.
Now rotate trimming hand wheel, just drive worm gear to move in a circle by worm screw, can complete fine setting operation, worm and gear forms the reducing gear of a big retarding ratio, becomes small angle change after the large rotation of handwheel is delivered to worm gear.With the position of trimming hand wheel, relative change occurs after worm screw swings up and down, the pin-and-hole of cross coupler can make the travelling end of worm screw axially produce certain relative position change, and can carry out the Movement transmit of two turning axles of different axis.
After fine setting work completes, rotate and unlock handwheel, make eccentric wheel height point depart from worm screw, worm screw throws off worm gear downwards under the effect of stage clip, realizes the unblock of latch mechanism, and released state as shown in Figure 4.Now Manual micromatic device lost efficacy, and axle system can affranchise rotation under motor control.
