Abstract
The present invention discloses bidirectional synchronous telescoping and locating method and device. The bidirectional synchronous telescoping and locating device includes one pedestal, two saddle racks on two ends of the pedestal, and one screw regulating mechanism set between the racks. The screw regulating mechanism includes one bidirectional screw comprising one right-handed screw and one left-handed screw in the same thread pitch, one central hand wheel in the middle part, one right-handed sliding block and one left-handed sliding block separately matching the right-handed screw and the left-handed screw, and two forcers in the outer ends of the bidirectional screw for contacting the objects to be located. Turning the central hand wheel makes the two sliding blocks slide linearly and oppositely in the rack grooves. The present invention may be applied in bidirectional synchronous locating and clamping of large member in welding and machining.
Description
Technical field:
The present invention discloses a kind of bidirectional synchronous telescopic positioning method, and the device that utilizes this method to make also is provided simultaneously, relates to the positioning clamping device technical field of large-scale component welding and processing.
Background technology
At present, use instruments such as traditional pole, strut, thimble aspect the location clamping in welding of rail vehicle large-scale component and processing.These devices are difficult to guarantee the symmetry of two-way location.And instruments such as traditional pole, strut, thimble use itself and can not place separately, need be attached to be positioned between the member that clamps, and just come off voluntarily after unclamping, because itself very heavily is very easy to fall to hurting sb.'s feelings suddenly.
Summary of the invention
The present invention discloses a kind of bidirectional synchronous telescopic positioning method, solves the inaccurate problem of symmetrical precision in the large-scale component processing.
The present invention also provides a kind of novel bidirectional synchronous telescopic positioner, and the clamping of bi-directional synchronization location is carried out in large-scale component welding and processing, satisfies symmetrical required precision.
Technical scheme of the present invention is achieved in that has the synchronization-moving spiral guiding mechanism of bi-directional symmetrical, has left and right reverse-flighted screw structure, the identical rotation direction of the pitch of left and right reverse-flighted screw is opposite, left and right sides reverse-flighted screw with about to revolve sliding shoe be that spiral cooperates, when centre wheel rotates a circle, about revolve sliding shoe and move a pitch stroke respectively to the left or to the right; When centre wheel rotates the N circle, about revolve sliding shoe mobile to the left or to the right N pitch stroke respectively, flexible push rod is done rectilinear motion about revolving sliding shoe about simultaneously and driving, about the top realization of flexible push rod object is held out against or release function.
Concrete structure of the present invention is: the two ends at base are provided with saddle support, set up the spiral guiding mechanism therebetween, the spiral guiding mechanism be a left and right sides reverse-flighted screw that the identical rotation direction of pitch is opposite, intermediate projections partly is manual centre wheel, the reverse-flighted screw at two ends cooperates with left-handed sliding shoe, dextrorotation sliding shoe spiral respectively, be fixed on the support by pressing plate, centre wheel can make left-handed sliding shoe, dextrorotation sliding shoe linear slide in the support groove when rotating, and the outer end of reverse-flighted screw is provided with the top and contacts with the object that needs the location to hold out against.The identical rotation direction of the pitch of left and right sides reverse-flighted screw is opposite, left and right sides reverse-flighted screw with about to revolve sliding shoe be that spiral cooperates.When centre wheel rotates a circle, about revolve sliding shoe and move a pitch stroke respectively to the left or to the right; When centre wheel rotates the N circle, about revolve sliding shoe mobile to the left or to the right N pitch stroke respectively, have the synchronization-moving characteristic of bi-directional symmetrical, revolve the push rod that stretches about sliding shoe drives about simultaneously to do rectilinear motion.Center of rotation wheel, about the top of flexible push rod hold out against or unclamp the object that needs the location to hold out against.
Apparatus of the present invention can be placed on any plane, and the expansion link at two ends and top can be changed as required, can make the different size expansion link and come directly towards standby.This device itself has pedestal, can be placed on any plane, and safety is not hurted sb.'s feelings.
Advantage of the present invention and progressive being: the bidirectional synchronous telescopic locator can be substituted in clamping aspect, location in large-scale component welding and the processing and use instruments such as the pole of prior art, strut, thimble.The inaccurate problem of symmetrical precision in large-scale component welding of solution rail vehicle and the processing is carried out the clamping of bi-directional synchronization location to large-scale component welding and processing, satisfies symmetrical required precision.Guarantee independent placement simultaneously, safe and reliablely do not hurt sb.'s feelings.
