Description

A kind of flange positioner of its locking device of rapid adjustment

Technical field

The present invention relates to can its locking device of rapid adjustment flange positioner, for parallel surface, the axiality of control flange and pipeline welding process, to meet code requirement.

Background technology

The inventor is at Chinese patent notification number CN1212912C, the day for announcing: on August 3rd, 2005, invention and created name is in flange positioner, adopted the flange positioner being formed by positioner and locking device, during flange centering, do not need parallel surface, axiality to flange to carry out leveling and adjusting, just can complete fast and accurately flange location.

Summary of the invention

The object of the invention is further to improve locking device and the positioner of flange positioner, make the quick and convenient dismounting of its locking device energy, can according to the flange of different size and pipeline fast and convenient locking device is adjusted to applicable scope, positioner can also position packing ring and retractable handle, makes dead load alleviate simultaneously.

For achieving the above object, locking device of the present invention is the skeleton by locking device, the composition such as spring and tensioning block, it is characterized in that: one end and the locating shaft of locking device skeleton are spirally connected, its another end peace groove closing cap, its jackshaft is along the axial length direction groove of circumference equalization, the cross section of groove is that top is narrow groove, bottom is wide groove, several springs and magnet piece are housed in the wide groove of bottom, at spring with above magnet piece, pacify pressure spring plate, pressure spring plate heads on the bottom of narrow groove on the top of wide groove, the upper surface of magnet piece with below pressure spring plate, contact installation, or make magnet piece from the open-work of pressure spring plate, insert installation, magnet piece is up-small and down-big step cylinder, pressure spring plate pressing spring, the small end on magnet piece top injects and installs from the bottom of stage clip plate hole, make the upper surface of magnet piece and the upper plane parallel of pressure spring plate, on pressure spring plate, pacify tensioning block, the Leading end chamfer of tensioning block or circular arc, so that insertion pipeline, the centre of skeleton can be also groove, peace spring in the middle of saturating groove, the layout strainer of both sides symmetry, tensioning block on pressure spring plate is held and can not depart from by the magnet under pressure spring plate, when locking device inserts pipeline, tensioning block is axially being positioned, can only do radial motion.

On the location-plate of positioner except along its plane is arranged a plurality of large magnetic columns near outer radius, its plane is arranged respectively a plurality of small magnet posts near inner radius, they can be positioned on arbitrary of location-plate, its outer radius is installed larger magnetic column, with locating flange dish, its inner radius is installed less magnetic column to hold the end cap of closed orientation packing ring and retractable handle, and can not take in use, compared with great strength, just can take moving.

The end cap of the retractable handle in locating shaft contacts with location-plate plane parallel in the outside of location axle head, and the small magnet post effect being positioned on board plane.

Below pressure spring plate, pacify magnet strip and carry out castering action power with increasing action area, because the intensity of magnet strip is poor, use pressure spring plate with protection magnet strip, also magnet strip can be clamped in pressure spring plate or with magnet strip for pressure spring plate.

Closed orientation packing ring is connected to form by moveable hinge, to facilitate, installs and dismounting.When closed orientation packing ring is installed, opening and closing space washer is close to location-plate and is positioned on locating shaft, by small magnet post, held, if full circle of space washer, when the external diameter of locking device is greater than closed orientation circle, must sheds locking device and just can set up closed orientation packing ring, enable to be inserted in closed orientation packing ring from locking device end, operate also loaded down with trivial detailsly, use closed orientation circle to save time and labour

The present invention is through using proof, during operation flange positioner, according to the flange of different size and pipeline, can change quickly and easily the tensioning block of locking device, only need clamp and take away the tensioning block of changing again another specification and put into hand, use tensioning block simple light quick again, save time and labour, and needn't change integral locking device or flange positioner, this structure is practical, and efficiency is high; The magnet that location-plate plane is installed near inner radius can hold closed orientation packing ring and not come off, change convenient and swift, use closed orientation circle to save time and labour, small magnet post also can hold operating handle and in indentation locating shaft, can not control oneself and skid off when not using simultaneously.

The specific embodiment

With reference to accompanying drawing, the invention will be further described, in Fig. 1, the positioner of the flange positioner of its locking device of rapid adjustment comprises location-plate 3 and locating shaft 8 and large magnetic column 2, small magnet post 4, in Fig. 2, locking device comprises skeleton 10, groove closing cap 12, magnet piece 14, spring 15, the spring bearer plate 16 of locking device.

While using flange positioner, its self-locking device can be changed tensioning block according to every batch of flange specification, first with hand, clamping the tensioning block 11 of taking away on locking device changes the tensioning block of another specification again and puts into, the mode of use tensioning block 11 can adapt to flange and the acting pipe locking needs of certain limit specification, and needn't change integral locking device or flange positioner, construction weight alleviates, and convenient disassembly is saved time and labour.

When closed orientation packing ring 6 is installed, opening circle is close to location-plate 3 and is positioned on locating shaft 8, and needn't be inserted in from the termination of locking device, small magnet post 2 on location-plate 3 can hold closed orientation packing ring 6 and can not come off, while changing closed orientation packing ring 6, with hand, clamp and take away the space washer of changing again another specification, use closed orientation circle 6 to save time and labour.

Use after flange positioner completion, in retractable handle 5 indentation locating shafts, the retractable handle end cap 7 axle 8 inner radius magnet 4 that are positioned hold and can not come off, and during use, grasp and pull out.

The above is only the preferred embodiment of the present invention, and protection scope of the present invention should comprise that those of ordinary skill in the art is not exceeding under the prerequisite of the principle of the invention, some modification and the improvement done.
