Abstract

The utility model provides an adjustable positioning shaft. The positioning shaft comprises a shaft sleeve and a shaft lever, wherein the positioning shaft axes of the shaft sleeve and the shaft lever are arranged in a square crossing manner; an opening connected with two positioning clamp plates is formed at one end of the shaft sleeve; and a butterfly nut is arranged on a positioning bolt and can adjust the clamping tightness of the shaft sleeve to the positioning shaft. The positioning shaft has the characteristics of ingenious conception, simple structure and reasonable design. The angle of a clamped workpiece can be adjusted in a multi-dimensional manner; the positioning is easy; a plurality of such positioning shafts can be connected together for the turning and contraposition fixation of workpieces requiring different welding angles; and the positioning shaft is especially suitable to be used with a welding positioning clamp to fix nonstandard weldments.

Description

Can regulate locating shaft

Technical field

The utility model relates to the auxiliary accessories of weld jig, particularly a kind of locating shaft of regulating.

Background technology

The major function of weld jig is to clamp soldered parts, guarantees that the position between each welded part is relatively accurate.In the production of reality, the weld jig metal sheet has strict corresponding relationship.The parts difference of welding, just needs are customized for the special fixture that needs in the welding.Running into has need the superpose welding or the professional enterprise of non-standard component welding is arranged often of plural workpiece, and making special weld jig becomes that the production cycle shortens and the main road blocking tiger of production cost reduction.This situation is particularly outstanding in remanufactured-vehicle business and solder technology training.

Relatively accurate in order to guarantee the position between the welded part, one of ordinary skill in the art have carried out unremitting effort to this.Chinese patent ZL 200720096245.4 disclosed " the adjustable weld jig of a kind of three-dimensional " for example, fixing welding needs when it can satisfy part weldment size less variation is arranged, but for the adjusting of needs multidimensional and shape and the diverse welding work pieces of welding manner, these anchor clamps can't adapt to.Chinese patent ZL 200520032691.X disclosed " a kind of weld jig that is used for miniature workpiece " and for example, this design can be satisfied the welding of part miniature workpiece, and complicated and complex-shaped welding work pieces still is difficult to adaptation for soldering angle.

The utility model content

At the prior art above shortcomings, the purpose of this utility model is to provide and can adapts to the soldering angle complexity and can regulate locating shaft.

The purpose of this utility model is achieved in that a kind of locating shaft of regulating, and it is characterized in that, comprises axle sleeve and axostylus axostyle, and the axial line of described axle sleeve and axostylus axostyle is the square crossing shape; One end of axle sleeve is provided with opening and links to each other with two positioning splints respectively; Two positioning splints be connected by bolt, the upper end of bolt is provided with the butterfly nut that is used to regulate the axle sleeve degree of tightness.

Compared to existing technology, the utlity model has following advantage:

The utility model is skillfully constructed, and is simple in structure, reasonable in design, but the multidimensional adjustment is held the angle of workpiece, and be easy to the location, this welding can turn to contraposition the workpiece that different soldering angles require and fix, and is particularly suitable for and the fixing non-standard weldment of the supporting use of positioning fixture for welding.

The specific embodiment

Below, in conjunction with the accompanying drawings and embodiments the utility model is elaborated.

As shown in Figure 1, a kind of locating shaft of regulating comprises axle sleeve 20a and axostylus axostyle 20d, and the axial line of described axle sleeve 20a and axostylus axostyle 20d is the square crossing shape; The end of axle sleeve 20a is provided with opening and links to each other with 20c with two positioning splint 20b; Two positioning splint 20b are connected by bolt 21a with 20c, and the upper end of bolt 21a is provided with the butterfly nut 21 that is used to regulate axle sleeve 20a degree of tightness.Rotate the angle that butterfly nut 21 is regulated the adjustable whole locating shaft of axle sleeve 20a degree of tightness.

Referring to Fig. 2, the weld jig that a kind of multidimensional is regulated comprises guide rail 2, move/positioning pedestal 5 and be installed on multi-dimensional regulation device on this pedestal; Described multi-dimensional regulation device comprises rotation principal arm 4, telescopic arm 6, screw rod 7, rocking arm 8 and locating shaft 9, and rotation principal arm 4 links to each other with mobile/positioning pedestal 5 by pivot pin 3; Telescopic arm 6 is the zigzag shape, and the lower end of telescopic arm 6 is socketed in the rotation principal arm 4, and the upper end is provided with screw-casing and cooperates with screw rod 7; The lower end of screw rod 7 is located on the pressing plate 10, and the upper end connects rocking arm 8; Can regulate locating shaft 20 by one to two on the locating shaft 9 and connect work piece positioning.Guide rail 2 is provided with at least two covers and moves/positioning pedestal 5 and the multi-dimensional regulation device that is installed on this pedestal.Described rotation principal arm 4, telescopic arm 6 can be tightened downwards at turn screw rod 7, and are fixed after pressing plate 10 and anchor clamps platen 1 compressed.Work piece positioning realizes that by a plurality of adjusting conversions of regulating locating shaft the multidimensional of angle or position changes.

Need to prove, above embodiment is only in order to illustrate the technical solution of the utility model but not the restriction technologies scheme, although the applicant has been described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are made amendment to technical solutions of the utility model or are equal to replacement, and do not break away from the aim and the scope of the technical program, all should be encompassed among the claim scope of the present utility model.
