The specific embodiment
As shown in Figure 1, the present invention 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; Said 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 through driver part between handle and the bearing pin, through pulling handle bearing pin is moved in cover for seat; Said main dowel mechanism 1 vertically is installed on the working plate 13; Said working plate 13 is installed on slide block 10 and the guide rail 11,
Installation process is following:
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 through the screwed hole on the installing plate 13, and below lean out appropriate length, the bulb that guarantees the bulb jackscrew is when work, the elastic force of the spring that bulb is suffered is accomplished the back and is locked with nut 4 in 90N ~ 140N scope;
3, with main dowel mechanism 1 through screw 2 with pin 3, attach it on the installing plate 13;
4, through 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, the assurance assembly 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 through screw 9 and pin 8; This step will guarantee the positional precision of locating piece; When making the dead in line in axis and locating piece 6 upper conical nest holes of bulb jackscrew, the 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 detent mechanism installs.
The course of work of 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 make the bearing pin lower end be higher than the upper surface of lining 7 on the locating piece 6 related bearing pin pull-up.Under this state, entire mechanism can be moved along the guide rail direction through 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 inner spring stress compression of bulb jackscrew 5 at the component of direction straight up through transmission, and along with the continuation of motion, bulb also can rise on the chamfering inclined-plane, continues the compression 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 because of receiving the elastic force that is in the compressive state lower spring automatically.At this moment, bulb because of the elastic force that receives 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.Promptly arrived the operating position this moment, and accomplished coarse positioning, can the handle of main dowel mechanism 1 have been pulled duty, bearing pin is pushed, and sword is gone in the lining 7 on the locating piece 6, accomplishes fine positioning (as shown in Figure 3).If want to make mechanism to get into next operating position, but then applied thrust makes mechanism continue motion, gets into next operating position up to mechanism, repeats said process.So far, entire work process finishes.
The ingenious design feature of utilizing spring performance and the spheroid and the conical surface of this mechanism; Realized accurately locating fast; Do not need the direct observation of operating personnel to operate, reduced requirement, saved the operating time operating personnel's ability and experience; 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.
More than one embodiment of the present of invention are specified, but said content is merely preferred embodiment of the present invention, can not be considered to be used to limit practical range of the present invention.All equalizations of doing according to application range of the present invention change and improve etc., all should still belong within the patent covering scope of the present invention.
