Abstract
The utility model discloses a locator for automatically centering a guide pipe for coaxial welding, which comprises a locating disc coaxially connected with a core shaft. The core shaft is a movable cylinder which is composed of three sector bodies with equal circumference, and all sector bodies symmetrically extend to the locating disc in a radial direction and symmetrically intersect in the center line of the locating disc. An expanded reducing cylinder is formed on an axial direction. A conical body connected with a handle is arranged in a central conical hole of the core shaft, and the conical body is driven by rotating a compression screw arranged in a radial sliding channel of the locating disc to do a downward linear motion. The sector bodies expanded in the radial direction form the core shaft 1, and a boss on the core shaft slides in a square hole of the locating disc. By the acting force of synchronous outside push of the linear motion of the conical body connected with the handle in the central conical hole along a normal direction, the locator automatically centers the inner part of a tubular piece to correct the non-cylindricity, ensures the coaxiality of guide pipe parts after welding, can prevent contraction distortion during welding, and efficiently solves the problem of the coaxiality of guide pipe parts after welding.
Description
Technical field
The utility model relates to a kind of frock clamp that can be widely used in all kinds of cylinder parts location welding of axiality requirement.
Background technology
At present a large amount of catheter parts welding, especially to the relative higher conduit welding of endoporus with the outer circles required precision, adopt usually be positioned at conduit two ends connecting plate and in opposite directions the detent mechanism of the steady pin composition of symmetrical weld seam realize.Catheter part one end endoporus to be welded by the steady pin on the connecting plate of two ends, is sleeved on the steady pin butt weld respectively.Because each part conduit endoporus tolerance difference, during with the changeless steady pin positioning catheter of nominal dimension part, radius non-adjustable, conduit detail welding back axiality can't realize coaxial, causes the coaxial precision of conduit weldering part to be difficult to guarantee.
Summary of the invention
The purpose of this utility model is can not guarantee conduit welding out-of-alignment problem at prior art, provide a kind of easy to use, self-centering conduit coaxial welding locator simple to operate, can be in radial extension adjustable, the problem that axiality is difficult to guarantee when solving the welding of catheter part.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of self-centering conduit coaxial welding locator comprises the positioning disk of a coaxial connection mandrel.It is characterized in that, described mandrel is a movable cylinder of being made up of the segment of three circumference in equal parts at least, each segment is all extended towards described positioning disk diametrically symmetrically, and symmetry intersects at the center line of positioning disk, form a hypertonic reducing cylinder in the axial direction, in the center of described mandrel is a conical bore that is complementary with bullet, stepped cylinder on the bullet is by the centered cylinder step of positioning disk, the housing screw of bullet by being provided with in the rotation positioning disk radial groove, downward rectilinear motion is made in drive, radially the mandrel of spreading segment composition makes in the square hole of boss in positioning disk 3 on its mandrel and slides.
The utility model has following beneficial effect than prior art.
The utility model axially is being provided with a hypertonic reducing cylinder mandrel, the rectilinear motion measure of the bullet 2 by connecting handle in the center circle taper hole is along the normal direction active force of extrapolation synchronously, to in the cylindrical member through self-centering, correct its not cylindricity, guaranteed conduit detail welding back axiality, and the contraction distortion that takes place can prevent to weld the time, solved the problem of catheter part welding axiality effectively.This conduit welded retainer simple and flexible, assembly is easy, and is easy to maintenance, good operability.Device is simple, practical, with short production cycle, can be widely used in the welding of all kinds of cylinder parts of axiality requirement, greatly increases work efficiency under the condition that satisfies the product required precision.
Description of drawings
Fig. 1 is the utility model self-centering conduit coaxial welding locator sectional plan view.
Fig. 2 be positioning disk with mandrel be connected the profile schematic diagram.
Among the figure: 1 mandrel, 2 bullets, 3 positioning disks, 4 springs, 5 slide blocks, 6 handles, 7 straight pins, 8 screws, 9 housing screws.
The specific embodiment
Consult Fig. 1, Fig. 2, the utility model provides self-centering conduit coaxial welding locator, has the positioning disk 3 of a coaxial connection mandrel 1.This mandrel 1 is a movable cylinder of being made up of the segment of three circumference in equal parts at least, and present embodiment is the segment of quartering circumference.Each segment is all extended towards described positioning disk 3 diametrically symmetrically, and the symmetrical center line that intersects at positioning disk 3, forms a hypertonic reducing cylinder in the axial direction.In the center circle taper hole of described mandrel, be provided with the bullet 2 that connects handle, bullet 2 drives by the housing screw 9 that is provided with in rotation positioning disk 3 radial grooves and makes downward rectilinear motion, radially the mandrel 1 of spreading segment composition makes in the chute of its segment in positioning disk 3 and slides.
The screw 9 that has handle 6 is by in the positioning disk 3 supercentral boss cylinder centre bores, link to each other with the bullet 2 in the endoporus in positioning disk 3 boss, there is a bit of its diameter of no screw thread housing screw 9 bottoms less than threaded portion, by being threaded in the positioning disk 3 and will entering in the T type groove in the bullet 2, rotatably compress screw 9 like this and will make bullet 2 along rectilinear motion up and down in the center hole of positioning disk 3 less than threaded portion.The boss of mandrel 1 by its fan-shaped upper position is placed in the rectangular groove on the positioning disk 3, and the screw thread in the boss of slide block 5 usefulness screws 8 and mandrel 1 fan-shaped upper position is connected, and mandrel just can not break away from positioning disk at above-below direction like this.Compression spring 4 is packed in the positioning disk 3 in the rectangular groove, and straight pin 7 is by the hole in the rectangular groove direction in compression spring 4 endoporus, the positioning disk 3 and the hole pressing of the fan-shaped top of mandrel 1 boss outer rim, and so spring is close to the bullet surface with four mandrels.Can do downward rectilinear motion by rotatably compressing screw 9 drive bullets 2, bullet and four mandrels rub by the conical surface and make radially spreading, and like this, four fan-shaped mandrels keep the equal diameter convergent-divergent all the time on disk.Realize conduit flexible retainer mechanism like this.
Its operation principle is: the operation housing screw makes mandrel be contracted to minimum diameter: mandrel is made up of four fan-shaped mandrels, rely on four core assembly axles and spring with four fan-shaped bullet surfaces of being close to, bullet and four mandrels rub by the conical surface and do radially spreading motion, like this, four fan-shaped mandrel keeps the equal diameter convergent-divergent all the time on disk radial motions.This locator is put into conduit, the joint that needs welding, and allow the positioning disc end face be close to the conduit end face; The operation housing screw is to tightening state, and at this moment, the mandrel spreading also is close to conduit or inner nosepiece wall, can finish the product welding; Operate housing screw once more flexible mandrel is shunk, at this moment, unload this locator, finish this parts welding sequence.Thereby reach self-centering, and correct its not cylindricity, contraction distortion of taking place when preventing to weld simultaneously cylindrical member.
