Description

Magnetically positioning gas-cutting multipurpose compasses
How the present invention relates to a kind of magnetic force location gas cutting advises with the garden.
The instrument of gas cutting garden shape has automatic gas cutting machine on steel plate at present, the homemade simple and easy garden of the employing that under the condition of manual oxygen cutting, has rule, its keeper is the Cylinder of a band awl point, need make a call to a little taper hole during use on steel plate, by deadweight the awl point is located to taper hole.The automatic gas cutting machine volume is big, carries inconvenience, simple and easy garden predetermined bits instability.The two all can not use on vertical plane or curved surface.
Task of the present invention provides a kind of easy to carry, and the location is reliable, and can be on vertical plane and curved surface the aid (what form on curved surface is approximate garden) of manual oxygen cutting garden shape.The present invention can also assist the chamfering of the various angles of gas cutting on the shape workpiece of garden, and rules on workpiece.
The magnetic that the present invention uses permanent magnet is to being located by gas cutting spare, and positioner can be made two kinds of adjustable magnetic-type and non-adjustable magnetic-types.Fig. 1 is the schematic diagram that garden rule are worked on the vertical plane.Fig. 2 is the schematic diagram that garden rule are worked on curved surface.Fig. 3 is a garden rule annex scriber.Fig. 4,5, the 6th, three views of adjustable magnetic-type.Fig. 7,8, the 9th, three views of non-adjustable magnetic-type.
Fig. 1 is the schematic diagram that garden rule are worked on the vertical plane, garden rule (1) are inhaled on the workpiece (3) on vertical plane, the nozzle of cutting torch (2) is by garden stipulations bundle, its movement locus is a garden, Fig. 2 is the schematic diagram that garden rule are worked at curved surface, garden rule (1) are inhaled on curve surface work pieces (4), and the nozzle of cutting torch (2) is restrained, and its movement locus is an approximate garden. The regulatable magnetic force formula is shown in Fig. 4,5,6. Fig. 4 is that front view, Fig. 5 of garden rule is that top view, Fig. 6 that advise in the garden is the full sectional view of A direction among Fig. 4, from seeing the assembly relation of other part from (1) to (16) on scheming clearly. Scale (1) is to be welded to form by the straight-bar of a strip length groove and the more than half garden plate with the angle groove. The bar that encircles (13) by sunk screw (11) and band bar garden forms chain connection. Length groove on scale (1) straight-bar represents to encircle the garden heart of (13) to the length at scale locating piece (2) center, just by the radius in gas cutting garden with the bar garden. Angle groove on the plate of the more than half garden of scale (1) represents the angle of the angle that scale (1) and the bar of being with bar garden ring (13) form. Tightening milled screw (12) can be to its angle locking, and this angle is the angle of gas cutting garden shape chamfering work piece just. When being 180 °, its angle is used for gas cutting on the plane. The relative scale (1) of band bar garden ring (13) can freely swing when unscrewing milled screw (12), is used for gas cutting on the curved surface this moment. The end of scale (1) also has one section internal thread, scale (1) can lengthen by extension bar when big by gas cutting spare radius, there is respectively internal and external threads at the extension bar two ends, and scale locating piece (2) is bearing on the support (3) by screw (9), milled screw (10). Screw (9) can use screw thread less than the special screw of root, also available common screw is stained with glue and screws the suitable degree of degree of tightness, assurance scale locating piece (2) can be done low-angle rotation on support (3), band bar garden ring (13) relatively can oscilaltion by gas cutting spare when gas cutting, is convenient to adjust nozzle of cutting torch and cuts by the distance of gas cutting spare with in the enterprising promoting the circulation of qi of curved surface. Screw (4) is connected support (3) together with above each part and permanent magnetism base (8), and requires (3) upper rotatable in (8) take (4) as axle. Iron core (5), non-magnetizer core (6) are entrenched togather and form the Cylinder with handle, and the handle on the end face and non-magnetizer core (6) are the same one of same material. There is a width to be slightly larger than screw (4) diameter at cylinder. Arc length is slightly larger than the garden arc groove of 1/4th girths, can do 90 ° of rotations in the hole, garden that permanent magnetism base (8) and non-magnetizer (7) form at Cylinder under the restriction of screw (4), and can not axial float. It is inner that non-magnetizer (7) works to stop that foreign material enter. The hard magnetic material manufacturing of the optional magnetic thermal good stability of permanent magnetism base (8). Gas cutting minor diameter garden can at simple shape heat shield of permanent magnetism base (8) outer cover, reduce the temperature rise of permanent magnetism base (8) in case of necessity. Spring compressor (14), pellet (16) are hold down gag. One of its effect is spring compressor (14) has pressure to more than half garden plate of scale (1), produces the hinge through damping, can avoid cutting torch to rock when unscrewing milled screw (12) gas cutting. Two of its effect is that pellet (16) compresses nozzle of cutting torch, guarantees that nozzle of cutting torch does not skid off band bar garden ring (13) (being preferably in cannelure of cutting on the nozzle).
Adjusting the mobile scale of milled screw (10) (1) when the present invention uses makes the length groove equal required radius.Adjust milled screw (12) turning joint structure, make the angle groove to required angle.Rotating the handle that fuses with non-magnetizer core (6) makes Cylinder be in position shown in Fig. 6 A-A cutaway view, at this moment permanent magnetism base (8) and iron core (5) constitute closed magnetic circuit, show that externally magnetic force is very weak, can put down or mobile contraposition from being picked up by gas cutting spare easily.Permanent magnetism base (8) bottom surface is a square, so with the i.e. contraposition of two mutually perpendicular center lines in its four angular alignment gardens.Handle rotates 90 ° after the contraposition, permanent magnetism base this moment (8) with constituted closed magnetic circuit by gas cutting spare, produce very big suction between them, thereby realize the magnetic force location.
An alternative embodiment of the invention is simple non-adjustable magnetic-type, shown in accompanying drawing 7,8,9.Can take out iron core (19) is a Cylinder, and an end, is inserted in non-flux sleeve (17) hole in conjunction with the in addition part (1) in the precedent, (2), (3) and from (9) to (16) 11 members of part compositions in addition by screw (4) totally.Permanent magnetism base (20), non-flux sleeve (17) are bonded as one with lid (18) with glue.Elder generation's dial-out can be taken out iron core (19) during use, and permanent magnetism base (20) is inhaled by on the gas cutting spare, and at this moment suction can be taken out iron core (19) and be inserted in non-flux sleeve (17) hole by mobile contraposition on the gas cutting spare not too by force after the contraposition.Permanent magnetism base this moment (20) lid (18) can be taken out iron core (17) and be constituted closed magnetic circuit by gas cutting spare, thereby to become the big magnetic force location of realizing by gas cutting spare suction.
If scriber is as shown in Figure 3 inserted in ring (13) hole, band bar garden, can on workpiece, rule.
The axial line of scale (1) was 42mm apart from the height of permanent magnetism base (8) baseplane when the present invention joined the product G01-100 of Shanghai Welding and Cutting Tool Factory type injector cutting torch, the diameter in ring (13) hole, band bar garden is 16mm, the bottom side length of permanent magnetism base (8) is 40-50mm, and the length of scale (1) is 800mm.In addition, increase by one to two of scale extension bar, scale extension bar length is 800mm.If when joining other model cutting torch, require the axial line of cutting torch scale (1) when the operating position approximate parallel with permanent magnetism base (8) bottom surface.The aperture of band bar garden ring (13) is than the big 1mm of nozzle of cutting torch diameter.
