Abstract

The utility model discloses an auxiliary adjusting device for butt welding, which relates to an auxiliary device for welding and comprises at least one pair of paired fixed seats which are respectively fixed on two adjacent welded pieces, the paired two fixed seats are connected through a screw rod which is in threaded connection with the two paired fixed seats, and screwing directions of the threads at two ends of the screw rod are reverse. The auxiliary adjusting device for butt welding can simply and effectively control butting evenness of the welded pieces of the butt welding and uniformity of gaps of welded joints.

Description

The butt welding auxiliary conditioning unit
Technical field
The utility model relates to a kind of auxiliary welding equipment, relates in particular to a kind of butt weld spacing adjusting device.
Background technology
In the steel case beam making of bridge construction, during plate butt welding, be the control welding deformation, need to guarantee the even of butt joint gap, reduce the distortion of postwelding, thereby guarantee integral manufacturing, the form accuracy of welding quality and whole steel case beam.Conventional way is at first smooth place will be arranged before the steel plate butt joint, then two boards is tiled on the place, through adjust roughly, stay dock the slit after, every horse plate of position welding of one meter, purpose is two boards to be pulled in together and to guarantee the width unanimity of abutment joint in the everywhere with the horse plate above abutment joint.The defective of this way is: 1, the bad control of butt joint flatness of two block plates; 2, can't finely tune repeatedly, the uniformity in butt joint gap can't guarantee; 3, regulating material can't reuse, and wastes bigger.
The utility model content
The purpose of this utility model is the problem that exists at above-mentioned prior art, proposes a kind of weldment butt joint flatness, the inhomogeneity butt welding auxiliary conditioning unit of weld gap that can control butt welding simply and effectively.
The purpose of this utility model realizes by following technical proposals:
A kind of butt welding auxiliary conditioning unit comprises at least one pair of the paired holder that is individually fixed on the two adjacent weldments, and by being connected with screw mandrel that it is threaded, and the thread rotary orientation at screw mandrel two ends is opposite between two paired holders.
As optimal way, also be provided with screw mandrel turn-knob mechanism on the described screw mandrel.
As optimal way, described screw mandrel turn-knob mechanism is two through holes that the interval is vertical that are positioned on the screw mandrel between holder.
As optimal way, be internal thread on the described holder, on the screw mandrel corresponding external screw thread.
The effect of each part is as follows in the utility model:
Guarantee the butt joint flatness of two adjacent weldments by the cooperation of holder and screw mandrel;
The thread rotary orientation at screw mandrel two ends is opposite, so the spacing that can regulate two holders by rotary screw, thereby adjusts the butt joint gap between weldment.
The effect of the rotation of screw mandrel by screw mandrel turn-knob mechanism realize, such as can be simply by the through hole turn-knob on the reinforcing bar insertion screw mandrel with rotary screw.
The beneficial effects of the utility model:
1. effectively controlled the butt joint flatness of two adjacent weldments.
2. adjusting device can be finely tuned repeatedly, has guaranteed the even of butt joint gap, reduces the distortion of postwelding.
3. adjusting device can be dismantled repeated use, has stopped the waste of material.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
Among the figure, 1 is steel plate, and 2 is nut, and 3 is screw mandrel, and 4 is external screw thread, and 5 is internal thread, and 6 is through hole.
The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
As shown in Figure 1, a kind of butt welding auxiliary conditioning unit comprises at least one pair of the paired holder that is individually fixed on the two adjacent weldments, and by being connected with its screw mandrel that is threaded 3, and the thread rotary orientation at screw mandrel 3 two ends is opposite between two paired holders.As optimal way, on the described holder internal thread 5, on the screw mandrel 3 corresponding external screw thread 4.Two block plates 1 as shown in this embodiment are weldment, and a pair of nut 2 on it is a holder, and this nut 2 is fixedly welded on the steel plate 1.As optimal way, also be provided with screw mandrel turn-knob mechanism on the described screw mandrel 3.As optimal way, described screw mandrel turn-knob mechanism is the vertical through hole 6 in two intervals that is positioned on the screw mandrel 3 between holder., insert in the through hole 6 as spanner with bar reinforcement, the rotation bar reinforcement is reconciled screw mandrel 3 length that are stuck between holder.Finally reach the gap of regulating butt joint steel plate 1 and satisfy code requirement.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.

Claims (4)

1. butt welding auxiliary conditioning unit is characterized in that: comprise at least one pair of the paired holder that is individually fixed on the two adjacent weldments, by being connected with screw mandrel that it is threaded, and the thread rotary orientation at screw mandrel two ends is opposite between two paired holders.
2. butt welding auxiliary conditioning unit as claimed in claim 1 is characterized in that: also be provided with screw mandrel turn-knob mechanism on the described screw mandrel.
