As shown in figures 1 and 2, the welding fixture of the utility model comprises a bottom plate 1, a fixed strip 4 is formed by upward protrusion of the center of the surface of the bottom plate 1, a sliding groove is arranged on the surface of the fixed strip 4, a sliding block 5 is movably arranged in the sliding groove, a fixed part 17 is formed by upward protrusion of the surface of the bottom plate 1 at both sides of the fixed strip 4, a support rod 6 is vertically arranged on the surface of the sliding block 5 and the surface of the fixed part 17, pipe clamps 10 are arranged at the upper ends of the support rods 6, fixed blocks 8 are arranged on the bottom surfaces of the pipe clamps 10, a cylindrical installation cavity is arranged in each fixed block 8, a through hole is arranged on the bottom surface of each fixed block, a cylindrical rotary block 7 is movably arranged in each installation cavity, the upper ends of the support rods 6 pass through holes and are arranged on the bottom surface of the rotary block 7, a first positioning mechanism for fixing the pipe clamps 10 is arranged at the upper ends, the lower end of the middle support rod 6 is provided with a second positioning mechanism, the pipeline pipe clamps 10 are all fixedly clamped with pipelines 11, and the end faces of the pipelines 11 are all abutted.
In this embodiment, first positioning mechanism all includes first screw rod 12, first hand wheel 13 and L template 14, fixed block 8 is the setting of cylindrical structure, all be equipped with more than one first screw hole 9 on the outer lane face of fixed block 8, L template 14 one end is all installed on bracing piece 6, the other end all extends to the outside of fixed block 8, L template 14 upper end all is equipped with the second screw hole, in the equal threaded connection of first screw rod 12 and the second screw hole, first screw rod 12 one end all inserts corresponding first screw hole 9, first hand wheel 13 all installs on the other end of first screw rod 12.
In this embodiment, second positioning mechanism includes second screw rod 3, fixed plate 2 and second hand wheel 16, the axial is equipped with more than one third screw hole on the surface of fixed strip 4, 2 one ends of fixed plate are installed on bracing piece 6 in the middle of, be equipped with the fourth screw hole on fixed plate 2, 3 threaded connection of second screw rod and fourth screw hole, 3 lower extremes of second screw rod insert in the corresponding third screw hole, and with third screw hole threaded connection, the perpendicular cross-section of slider and spout is the setting of dovetail structure, phase-match between slider and the spout, the slider has been avoided breaking away from in the spout.
In this embodiment, all install the universal wheel 15 of taking the brake on four angles of bottom plate 1 bottom surface, made things convenient for through the universal wheel to remove this device.
When the angle adjusting device is used, the angle of the pipeline pipe clamp is adjusted according to the angle during pipeline welding, when debugging is carried out, the first screw rod is firstly screwed out of the first screw hole, so that the pipeline pipe clamp can rotate by taking the rotating block and the supporting rod as centers, as shown in figure 2, after the pipeline pipe clamp rotates to a specified angle, the first screw rod is screwed into the first screw hole again, so that the pipeline pipe clamp is fixed, wherein in the angle adjusting process, the middle pipeline pipe clamp can be moved along the sliding groove, when in movement, the second screw rod is screwed out of the third screw hole, so that the sliding block can move freely, the movement of the sliding block drives the middle supporting rod and the pipeline pipe clamp, after the welding position is reached, the second screw rod can be screwed into the third screw hole again, the middle pipeline pipe clamp is fixed, so that the V-shaped shapes can be formed between the pipeline pipe clamps at two sides and the middle pipeline pipe clamp, thereby increasing the welding style between pipelines, after the completion, be fixed in the pipeline pipe clamp with the pipeline, make the terminal surface of three steel pipes offset, made things convenient for and welded it.
As shown in figure 3, the rotation angles of the pipe clamps at the two sides are different from the rotation angle of the middle pipe clamp, so that a structure similar to that of figure 3 is formed, and the welding comprehensiveness and practicability of the device are improved.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention.
