Abstract

The utility model relates to a 45-degree turnover mechanism for H-shaped steel, which comprises a first turnover arm, a second turnover arm, a bearing pedestal, a first base, a second base, a rotating shaft, a first pin shaft, a hydraulic cylinder and a second pin shaft, wherein the first turnover arm and the second turnover arm are welded in the middle of the rotating shaft respectively; one end of the bearing pedestal is fixed on the first base, and the other end of the bearing pedestal is fixed on the second base; the end part of the hydraulic cylinder is connected with the first turnover arm by the first pin shaft; the tail of the hydraulic cylinder is fixed on the second base by the second pin shaft; and shaft sleeves are arranged at both ends of the rotating shaft respectively, and the shaft sleeves are embedded into an inner ring of the bearing pedestal. The 45-degree turnover mechanism has a simple, compact and reasonable structure; when steel members are subjected to V-shaped welding, operators only need to aim a welding gun at welding lines at the beginning of the welding; and before being welded, workpieces are turned at 45 degrees automatically, so that the welding lines are in a V shape, and after the welding is finished, the 45-degree turnover mechanism restores automatically without manual intervention, so the quality of the welding lines can be improved, and the labor strength of workers is reduced.

Description

H shaped steel 45 degree switching mechanisms

Technical field

The utility model relates to a kind of 45 degree mechanical turnover devices of H shaped steel, when specifically welding for the steel member workpiece is overturn to use when making weld seam V-shaped, belongs to mechanical equipment technical field.

Background technology

In prior art, large-scale steel structure factory is when welded H section steel V-type weld seam, and operating personnel need workpiece is sling with driving, are placed on the shelf of 45 degree, hang away after welding is finished again, and have reduced production efficiency, and increase unsafe factor.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of H shaped steel 45 degree switching mechanisms, this mechanism adopts the stretching and the contraction principle of hydraulic cylinder, flip-arm is pivoted, realization 45 degree rotate and reset, can avoid effectively the driving a vehicle danger of handling reduces labor strength, increases work efficiency.

The technical scheme that provides according to the utility model, H shaped steel 45 degree switching mechanisms comprise first flip-arm, second flip-arm, bearing block, first base, second base, rotating shaft, first bearing pin, hydraulic cylinder, second bearing pin, described first flip-arm and second flip-arm are welded on the centre of rotating shaft respectively, described bearing block one end is fixed on first base, the other end is fixed on second base, the end of hydraulic cylinder is connected with first flip-arm by first bearing pin, and the afterbody of hydraulic cylinder is fixed on second base by second bearing pin.

Axle sleeve is equipped with at the two ends of described rotating shaft respectively, and axle sleeve is set in the inner ring of bearing block.

Compared with the prior art the utility model has the following advantages:

The utility model is simple, compact and reasonable for structure; When steel member V-type was welded, operating personnel only needed when the welding beginning to make weld seam V-shaped workpiece upset 45 degree with the welding gun weld seam that aligns automatically before the welding, automatically reset after the end, need not manual intervention, can improve weldquality, reduce labor strength.

The specific embodiment

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

As Fig. 1～shown in Figure 2, comprise first flip-arm 1, second flip-arm 2, bearing block 3, axle sleeve 4, axle sleeve 4, bolt 5, bullet pad 6, first base 7, second base 8, rotating shaft 9, first bearing pin 10, hydraulic cylinder 11, second bearing pin 12 etc.

The utility model adopts first flip-arm 1 and second flip-arm 2 to be welded on the centre of rotating shaft 9 respectively, axle sleeve 4 is equipped with at the two ends of described rotating shaft 9 respectively, axle sleeve 4 is set in the inner ring of bearing block 3, described bearing block 3 one ends are fixed on first base 7 by bolt 5 and bullet pad 6, the other end is fixed on second base 8 by bolt 5 and bullet pad 6, the end of hydraulic cylinder 11 is connected with first flip-arm 1 by first bearing pin 10, and the afterbody of hydraulic cylinder 11 is fixed on second base 8 by second bearing pin 12.

The utility model operation principle and process work:

During the utility model work, when the emersion of the end of hydraulic cylinder 11, drive first flip-arm 1 and second flip-arm 2 and rotating shaft 9 and rotate to horizontal level around bearing block 3 inner rings; When the retraction of the end of hydraulic cylinder 11, drive first flip-arm 1 and second flip-arm 2 and rotating shaft 9 and rotate to 45 degree positions around bearing block 3 inner rings.By stretching of control hydraulic cylinder 11, drive the automatic rotation between level and 45 degree of first flip-arm 1 and second flip-arm 2.
