A kind of flange positioner of its locking device of rapid adjustment
Technical field
But the present invention relates to the flange positioner of its locking device of rapid adjustment, be used 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 the flange positioner, adopted the flange positioner of forming by positioner and locking device, do not need parallel surface, axiality to carry out the centering adjustment during flange centering, just can finish the flange location fast and accurately flange.
Summary of the invention
The objective of the invention is further to improve the 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, and dead load is alleviated.
For achieving the above object, locking device of the present invention is the skeleton by locking device, compositions such as spring and tensioning piece, it is characterized in that: an end and the locating shaft of locking device skeleton are spirally connected, it is end peace groove closing cap in addition, its jackshaft is along the axial length direction groove of circumference equalization, the cross section of groove is that top is narrow groove, the bottom is a wide groove, several springs and magnet piece are housed in the wide groove of bottom, at spring and peace pressure spring plate above the magnet piece, pressure spring plate heads on the bottom of narrow groove on the top of wide groove, the upper surface of magnet piece contacts installation below pressure spring plate, or make magnet piece from the open-work of pressure spring plate, insert installation, magnet piece is up-small and down-big step cylinder, the pressure spring plate pressing spring, the small end on magnet piece top injects from the bottom of stage clip plate hole and installs, make the upper surface of magnet piece and the last plane parallel of pressure spring plate, peace tensioning piece on pressure spring plate, the Leading end chamfer of tensioning piece or circular arc, so that insertion pipeline, the centre of skeleton also can be a groove, peace spring in the middle of saturating groove, the layout strainer of both sides symmetry, tensioning piece on the pressure spring plate is held by the magnet under the pressure spring plate and can not break away from, when locking device inserted pipeline, the tensioning piece axially had been positioned, and can only do radial motion.
On the location-plate of positioner except that arranging a plurality of big magnetic columns near outer radius along its plane, its plane is arranged a plurality of small magnet posts respectively near inner radius, they can be positioned on arbitrary of location-plate, its outer radius is installed bigger magnetic column, with the locating flange dish, its inner radius is installed less magnetic column to hold the end cap of closed orientation packing ring and retractable handle, just can take moving and can not take in use than great strength.
The end cap of the retractable handle in the locating shaft contacts with the location-plate plane parallel in the outside of location axle head, and the small magnet post effect on the board plane that is positioned.
The peace magnet strip comes castering action power to increase active area below pressure spring plate, because the intensity of magnet strip is relatively poor, uses pressure spring plate with the protection magnet strip, also can clamp magnet strip in the pressure spring plate or with magnetic stripe and replace pressure spring plate.
The closed orientation packing ring is connected to form by moveable hinge, installs and dismounting with convenient.When the closed orientation packing ring is installed, the opening and closing space washer is close to location-plate and is positioned on the locating shaft, held by the small magnet post, if full circle of space washer when the external diameter of locking device during greater than the closed orientation circle, must shed locking device and just can set up the closed orientation packing ring, promptly be to be inserted in the closed orientation packing ring from the locking device end, operate also loaded down with trivial detailsly, use the closed orientation circle to save time and labour
The present invention is through using proof, during the operation flange positioner, the tensioning piece that can change locking device quickly and easily according to the flange and the pipeline of different size, only with hand is clamped and is taken away the tensioning piece of changing another specification again and put into and get final product, use the tensioning piece simple light quick again, save time and the labour, and needn't change integral locking device or flange positioner, this structure is practical, the efficient height; The magnet that install near inner radius on the location-plate plane can hold the closed orientation packing ring and not come off, change convenient and swift, use the closed orientation circle to save time and labour, the small magnet post also can hold operating handle simultaneously and can not control oneself in the indentation locating shaft when not using and skid off.

The contrast description of drawings press each concrete parts in the order further explanatory drawings of Fig. 1 to Fig. 3: among Fig. 1: 1, flange, 2, magnetic column greatly, 3, location-plate, 4, the small magnet post, 5, retractable handle, 6, closed orientation packing ring, 7, retractable handle end cap, 8, locating shaft, 9, the retractable handle nut, 10, locking device skeleton, 11, tensioning piece, 12, the groove closing cap, 13 pipelines; Among Fig. 2: 14, magnet, 15, spring, 16, spring bearer plate; Among Fig. 5: 17, magnet strip; Among Fig. 6: 18, moveable hinge.
The specific embodiment
With reference to accompanying drawing, the invention will be further described, among Fig. 1, the positioner of the flange positioner of its locking device of rapid adjustment comprises location-plate 3 and locating shaft 8 and big magnetic column 2, small magnet post 4, among Fig. 2, locking device comprises skeleton 10, groove closing cap 12, magnet piece 14, spring 15, the spring bearer plate 16 of locking device.
When using flange to decide device, its self-locking device can be changed the tensioning piece according to every batch of flange specification, earlier clamping the tensioning piece of taking away on the locking device 11 with hand changes the tensioning piece of another specification again and puts into and get final product, the mode of use tensioning piece 11 can adapt to the flange and the pipeline 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 the labour.
When closed orientation packing ring 6 is installed, opening circle is close to location-plate 3 and is positioned on the locating shaft 8, and needn't be inserted in from the termination of locking device, small magnet post 2 on the location-plate 3 can hold closed orientation packing ring 6 and can not come off, when changing closed orientation packing ring 6, clamp with hand and to take away the space washer of changing another specification again and get final product, use closed orientation circle 6 to save time and labour.
After using the flange positioner completion, in the 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 grasp during use to pull out to get final product.
The above only is a preferred implementation of the present invention, and protection scope of the present invention should comprise those of ordinary skill in the art under the prerequisite that does not exceed the principle of the invention, some modification and the improvement done.
