Description

Tool clamp for welding longitudinal seam electron beam of air cooler tube box

Technical Field

The utility model belongs to the welding tool field, concretely relates to air cooler pipe case frock clamp for longitudinal joint electron beam welding.

Background

The welding of the air cooler pipe box is an important link in production and manufacturing, the welding efficiency of the pipe box is also considered when the welding quality of the pipe box is guaranteed in actual production, in order to improve the quality and efficiency of the nickel-based alloy 825, the longitudinal seam of the pipe box is welded by adopting electron beams, the electron beam welding requires accurate joint positions, small and uniform gaps, the requirements on joint groove machining, assembly and cleanliness before welding are extremely strict, so that the assembly precision needs to be guaranteed when the pipe box is assembled, special equipment is generally needed to clamp a workpiece, the existing clamping workpiece cannot meet the problem of deformation in the welding process of the longitudinal seam of the air cooler pipe box, and the precision after welding is insufficient.

Disclosure of Invention

Based on above weak point, the utility model provides an air cooler pipe case is frock clamp for longitudinal joint electron beam welding for air cooler pipe case longitudinal joint welding can reduce the deflection, has improved the precision of pipe case welding seam.

The technical proposal adopted by the utility model is as follows: the utility model provides an air cooler pipe case is frock clamp for longitudinal joint electron beam welding, includes base and welding bench, the welding bench includes many spacing stands and carrier block, the many spacing stands of welding bench upper surface according to certain interval fixedly connected with to constitute spacing stand array, spacing stand array be the triplex row along the width direction of welding bench, length direction is a plurality of rows, distance between the spacing stand of two adjacent rows cooperatees with the width of required welded pipe case.

Furthermore, the outer side wall threads of each limiting upright column in the first row and the third row are in through connection with a jackscrew, so that the position between the tube box to be welded and the limiting upright columns can be fixed.

Further, still include two sets of carrier blocks, all placed the carrier block between the spacing stand of two columns that are close to the welding bench both ends.

Furthermore, an insulating support is detachably and fixedly connected between the base and the welding table.

The utility model has the advantages of: the utility model discloses simple structure, effectual control the deformation in the welding process of pipe case, improve welding efficiency and welding quality.

Detailed Description

As shown in fig. 1-3, a tooling fixture for electron beam welding of a longitudinal joint of an air cooler tube box comprises a base 1 and a welding table 2, wherein the welding table 2 comprises a plurality of limiting upright columns 3 and two groups of bearing blocks 4, the upper surface of the welding table 2 is fixedly connected with the plurality of limiting upright columns 3 at certain intervals so as to form a limiting upright column array, the limiting upright column array is three rows along the width direction of the welding table 2, the length direction of the limiting upright column array is a plurality of rows, the distance between two adjacent rows of limiting upright columns 3 is matched with the width of the tube box to be welded, and the bearing blocks 4 are respectively arranged between two rows of limiting upright columns 3 close to two ends of the welding table 2; the outer side wall of each limiting upright post 3 in the first row and the third row is in threaded through connection with a jackscrew 5, so that the position between the tube box to be welded and the limiting upright posts 3 can be fixed; the base 1 and the welding table 2 are fixedly connected with an insulating support 6 in a detachable mode.

The utility model discloses when the installation: the tube box to be welded is placed in the middle of each row of limiting upright columns 3, then the jackscrews 5 are adjusted to clamp the tube box, and after the tube box is assembled, the welding table 2 is fixedly installed on the base 1 of the electron beam welding table through the insulating support 6, so that the tube box is fixed and positioned.

The utility model discloses a two pipe boxes of welding bench 2 can assemble simultaneously, if pipe box width dimension is different, can adjust according to jackscrew 5, if pipe box height dimension is different, the accessible increases and cancels carrier block 4 and adjusts, the length and the width of welding bench 2 are designed according to the size of electron beam equipment vacuum chamber, satisfy the electron beam with the biggest stroke, fix pipe box through this frock clamp, prevent that pipe box because the distance value that receives the thermal deformation and influence electron beam rifle to pipe box welding seam in welding process, pipe box longitudinal joint welds the back and hangs out welding bench 2 and pipe box wherein wholly, treat that the seam natural cooling takes out pipe box after to the room temperature, effectual control the deformation in the pipe box welding process.

When the electron beam equipment is used for welding, the space of the electron beam vacuum chamber is fully utilized, the two air cooler pipe boxes are assembled and fixed in the tool clamp for electron beam welding, four longitudinal seams of the two air cooler pipe boxes can be welded after primary vacuumizing, deformation of the pipe boxes can be effectively controlled, and welding efficiency and welding quality are improved.
