The specific embodiment
As shown in Figure 1, the utility model mainly comprises: main dowel mechanism 1, screw 2, pin 3, nut 4, bulb jackscrew 5, locating piece 6, lining 7, pin 8, screw 9, slide block 10, guide rail 11, screw 12, installing plate 13; Described main dowel mechanism 1 comprises handle, bearing pin, cover for seat and driver part, and bearing pin is installed in the cover for seat, and handle is installed in the cover for seat top, links to each other by driver part between handle and the bearing pin, makes bearing pin mobile in cover for seat by pulling handle; Described main dowel mechanism 1 vertically is installed on the working plate 13; Described working plate 13 is installed on slide block 10 and the guide rail 11,
Installation process is as follows:
1, guide rail 11 and slide block 10 are assembled together, and are fixed on the workbench 14;
2, bulb jackscrew 5 is fixed thereon by the screwed hole on the installing plate 13, and below lean out appropriate length, guarantee the bulb of bulb jackscrew when work, the elastic force of the spring that bulb is suffered in 90N ~ 140N scope, after finishing with nut 4 lockings;
3, main dowel mechanism 1 is passed through screw 2 and pin 3, attach it on the installing plate 13;
4, by the screw via hole on the installing plate and the screwed hole on the slide block, use screw 12 that mounted installing plate is installed on the slide block, Assurance component can be free to slide along the guide rail direction;
5, lining 7 is installed in the installing hole prefabricated on the locating piece 6, and the integral body that will assemble is installed on the workbench 14 by screw 9 and pin 8, this step will guarantee the positional precision of locating piece, when making the dead in line in the axis of bulb jackscrew and locating piece 6 upper conical nest holes, coaxiality deviation between the bearing pin axis of main dowel mechanism and the interior axially bored line of the lining on the locating piece 6 less than 0.05mm. so far, whole quick positioning mechanism installs.
The course of work of the present embodiment:
The handle of main dowel mechanism 1 is pulled off working state (as shown in Figure 2), and this moment, main dowel mechanism can with related bearing pin pull-up, make the bearing pin lower end be higher than the upper surface of lining 7 on the locating piece 6.Under this state, whole mechanism can move along the guide rail direction by manpower.When the installing plate in the motion during through the locating piece 6 of below, because the bulb lower end on the bulb jackscrew 5 is lower than the upper surface of locating piece 6, the edge chamfering inclined-plane of locating piece 6 can contact with its origination point of bulb, the generation extruding force.Extruding force can make the spring stress compression of bulb jackscrew 5 inside by transmission at the component of direction straight up, along with the continuation of motion, bulb also can rise on the chamfering inclined-plane, continues Compress Spring.Keep compressive state at this process medi-spring, bulb can contact with the surface of locating piece 6 bottom always always.Mechanism continues motion, and when bulb passed through taper nest hole prefabricated on the locating piece 6, bulb sank in the taper nest hole automatically because being subject to being in the elastic force of compressive state lower spring.At this moment, bulb because of the elastic force that is subject to spring in taper nest hole automatic guiding until stable.The bulb of spherical jackscrew can contact the i.e. dead in line in the axis of bulb jackscrew and taper nest hole with the line that the conical surface in taper nest hole produces a circle under this state.Namely arrived the operating position this moment, and finishes coarse positioning, the handle of main dowel mechanism 1 can be pulled duty, and bearing pin is pushed down, and sword enters in the lining 7 on the locating piece 6, finishes fine positioning (as shown in Figure 3).If want to make mechanism to enter next operating position, but then applied thrust makes mechanism continue motion, until mechanism enters next operating position, repeats said process.So far, the whole course of work is complete.
The ingenious design feature of utilizing spring performance and spheroid and the conical surface of this mechanism, realized accurately locating fast, do not need the direct observation of operating personnel to operate, reduced the requirement to operating personnel's ability and experience, saved the operating time, adapted to the demand of during flexible frock uses each duty being switched fast, be highly suitable in all kinds of flexible frocks and use.
Above an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
