Abstract
The utility model discloses a center-aligning type bidirectional size synchronously-adjusting mechanism, which belongs to the technical field of welding clamps, and comprises a base, a jacking shaft, a sleeve, a draw bar and a convex block, wherein the jacking shaft is inserted in a positioning hole of the base by way of penetrating, the jacking shaft is in clearance fit with the positioning hole of the base, the convex block is sleeved on the draw bar and fixed on a step face of the bottom of the draw bar, the periphery of the convex block is pressed against an end face of the jacking shaft, and the sleeve is fixedly connected with the draw bar. The mechanism disclosed by the utility model has the beneficial effects that: the expansion and contraction quantities of the jacking shaft are synchronously adjusted in two directions through the rotation of the convex block, so that the opening size of a part can be finely adjusted in a certain range, the accurate positioning of the part can be realized, and the important sizes such as symmetry degrees and the like of an elongated frame structure can be ensured; and the mechanism is simple in structure, convenient to process, high in reliability, and strong in commonality.
Description
Technical field
The utility model relates to a kind of to the two-way size synchronous adjusting mechanism of Chinese style, belongs to the weld jig technical field.
Background technology
Mostly the structural member of present domestic engineering machinery is the welded type frame structure; There is welding deformation in the welding process; Especially sleeve configuration Welding Structure is if positioning reference forwardly, under unconfined free state; The deflection of afterbody is maximum, and significant dimensions can't guarantee as opening grade size and symmetry.If between the afterbody framework, weld part again, and requirement and framework are inboard fits, seamless welding, but part opens grade size and in certain margin of tolerance, distributing, and just can't guarantee that the centering at the center of the relative general structure of this part is welded.
Summary of the invention
To the problem that above-mentioned prior art exists, it is a kind of to the two-way size synchronous adjusting mechanism of Chinese style that the utility model provides, can adjust out synchronously within the specific limits grade size to the two-way size of Chinese style.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of to the two-way size synchronous adjusting mechanism of Chinese style, comprise base, lifting axe, sleeve, pull bar and projection; Lifting axe is located in the base locating hole; Be matched in clearance between lifting axe and the base locating hole, projection is enclosed within on the pull bar, and projection is fixed on the pull bar bottom stage face; The projection periphery is against on the lifting axe end face, and sleeve is fixedly connected with pull bar.
Further, sleeve and pull bar are integrally welded.
Further, the pull bar outside is arranged with lining, is provided with packing ring and spring washer between lining and base, and connects through bolt.
Further, projection is fixed on the pull bar step surface through spot welding.
Further, projection periphery both sides are the inclined-plane that is parallel to each other.
The beneficial effect of the utility model is: the rotation through projection is from the two-way stroke of adjustment lifting axe synchronously of going up; Make opening grade size and finely tuning within the specific limits of parts; Can realize the accurate location of parts; And the significant dimensions such as symmetry of assurance sleeve configuration frame structure, it is simple in structure, easy to process, reliability is high, highly versatile.

Fig. 2 is the utility model structure vertical view;
Fig. 3 is the utility model projection cube structure sketch map.
Among the figure: 1, base, 2, lifting axe, 3, lining, 5, hex bolts, 7, sleeve, 8, pull bar, 9, projection.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
Like Fig. 1, Fig. 2 and shown in Figure 3, a kind of to the two-way size synchronous adjusting mechanism of Chinese style, comprise base 1, lifting axe 2, sleeve 7, pull bar 8 and projection 9; Lifting axe 2 is located in base 1 locating hole, is matched in clearance between lifting axe 2 and base 1 locating hole, and projection 9 is enclosed within on the pull bar 8; Projection 9 is fixed on pull bar 8 step surfaces through spot welding, and projection 9 periphery both sides are provided with some inclined-planes to being parallel to each other, the span diverse between the every pair of parallel inclined-plane; Projection 9 periphery inclined-planes are against on lifting axe 2 end faces; Pull bar 8 outsides are arranged with lining 3, and 1 of lining 3 and base are provided with packing ring and spring washer, and connect through hex bolts 5.Sleeve 7 is integrally welded with pull bar 8.
During installation, this guiding mechanism and weld jig are that bolt adds pin-and-hole and is connected, and guarantee that guiding mechanism is centered close on the center line of weld jig, and guiding mechanism is arranged in the afterbody of weld jig, and lifting axe 2 two ends are frame structure internal arm sizing faces.
Adjustment process: rotational sleeve 7; Drive pull bar 8 and rotate together with projection 9, projection 9 different angles, relative edge's span are also different; The variation of span drives both sides lifting axe 2 and slides synchronously to both sides; Thereby what make framework opens grade size with the adjustment synchronously on two-way direction of centering mode, to adapt to grade size of opening that adds the weldering part between framework, is the inboard and seamless applying of part of framework.
