Abstract
The utility model discloses a bidirectional synchronous stretching-positioning device. Saddle-shaped brackets are arranged at the two ends of a base, a helical adjusting mechanism is bridged between the two saddle-shaped brackets, the helical adjusting mechanism is left/right bidirectional screw rods with same screw pitch and opposite screwing directions, the bulge part in the middle is a manual center wheel, the bidirectional screw rods at the two ends are respectively matched with a left-screwing sliding block and a right-screwing sliding block in a screwing manner, the rotation of the center wheel can lead the left-screwing sliding block and the right-screwing sliding block to slide in a bracket groove along a straight line, a top head is arranged at the outer end of each bidirectional screw rod and is in contact with an object which needs to be positioned and tightly propped, the screw pitch of the left/right bidirectional screw rods is the same and the screwing directions are opposite, and the left/right bidirectional screw rods are matched with the left/right-screwing sliding blocks in a screwing manner. The bidirectional synchronous stretching-positioning device can carry out bidirectional synchronous positing and clamping on the welding and processing of large-sized components, and can satisfy the requirements for symmetrical precision. Moreover, the device can be separately placed for sure, so as to be safe as well as reliable and not to injure people; and the device solves the problem of inaccurate symmetrical precision in welding and processing the large-sized components.
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, when revolving centre wheel about simultaneously and rotating a circle, about revolve the mobile to the left or to the right respectively pitch stroke of sliding shoe; 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.
The utility model device 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 utility model 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.
Description of drawings
Fig. 1 is the utility model structure principle chart.
Specific embodiment
Be described below in conjunction with 1 pair of the utility model of accompanying drawing:
The bidirectional synchronous telescopic locator is made up of parts such as support 1, middle runner 2, left-handed sliding shoe 3, dextrorotation sliding shoe 4, pressing plate 5, the flexible push rod 6 in a left side, right flexible push rod 7, tops 8.
The two ends of base are provided with saddle support 1, 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 2, the reverse-flighted screw at two ends cooperates with left-handed sliding shoe 3, dextrorotation sliding shoe 4 spirals respectively, and centre wheel 2 can make left-handed sliding shoe 3, dextrorotation sliding shoe 4 linear slide in support 1 groove when rotating.The flexible push rod 6 in a left side, right flexible push rod 7 usefulness are threaded on left-handed sliding shoe 3 and the dextrorotation sliding shoe 4, then with nut 10 lockings.Pressing plate 5 usefulness bolts 11 and packing ring 12 are fixed on the support plate of support 1, push down left-handed sliding shoe 3 and dextrorotation sliding shoe 4, play the effect that the linear slide process prevents perk.Top 8 usefulness sunk screws 9 are fixed on the head of flexible push rod 6 in a left side and right flexible push rod 7, and top 8 contacts with the object that needs the location to hold out against.By center of rotation wheel 2, the left side at two ends stretch push rod 6, right flexible push rod push rod 7 synchronization telescope rectilinear motions, holding out against or unclamping needs locate the object that holds out against.
Claims (1)
1, a kind of bidirectional synchronous telescopic positioner, it is characterized in that: 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 respectively with left-handed sliding shoe, dextrorotation sliding shoe spiral cooperates, be fixed on the support by pressing plate, centre wheel can make left-handed sliding shoe when rotating, the dextrorotation sliding shoe is linear slide in the support groove, 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.
