Description

Chair leg subassembly welding frock

Technical Field

The utility model relates to a EMUs seat accessory processing technology field, in particular to chair leg subassembly welding frock.

Background

The seat is one of important parts of a motor train unit, and the installation requirement of the seat is extremely high. The chair leg assembly welding tool is one of important parts of a chair, and the requirement is extremely strict during assembly, specifically, the parallelism error of a cross beam of a chair leg and a chair leg mounting plate is required to be within 0.5 degree, and the perpendicularity error of a side and the chair leg mounting plate is also required to be within 0.5 degree. In the traditional manual workpiece-holding welding mode, the precision is poor, the requirement cannot be met, and a welded finished product is easy to deform, so that the chair leg assembly welding tool is specially designed and developed.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes prior art is not enough, provides a chair leg subassembly welding frock.

The utility model discloses a realize through following technical scheme: the utility model provides a chair leg subassembly welding frock, includes the base, its characterized in that, the four corners of base is equipped with limit stop respectively, and wherein between two limit stop on the left side, still the symmetry is equipped with clamping structure respectively between two limit stop on the right side, clamping structure is including installing the stand on the base, and the inboard of stand is equipped with U type groove, and the top and the front side of stand all are equipped with the clamp plate, and the clamp plate is rotatable to be installed on the stand, the middle part of base still is equipped with the crossbeam dog.

Preferably, the limit stop limits the bottom of the workpiece; the clamping structure limits the left side and the right side of the workpiece.

Preferably, the bottom plate is provided with a material taking hole.

The utility model has the advantages that: the utility model discloses a welding frock simple structure; the error is reduced by arranging the limit stop, the cross beam stop and the upright post, so that the high processing precision of a welded finished product is ensured; through set up the material hole of getting on the base, take out the welding finished product fast, reduce the deformation rate of welding finished product.

The utility model discloses simple to use, convenient operation, it is with low costs, machining efficiency is high.

Detailed Description

In order to make the objects, technical solutions and advantageous effects of the present invention more clear, the following embodiments are combined to further explain the technical solutions of the present invention.

As shown in fig. 1 to 4, a chair leg assembly welding tool, including base 1, base 1's four corners is equipped with limit stop 2 respectively, wherein between two limit stop 2 on the left side, still be equipped with a clamping structure 3 between two limit stop 2 on the right side respectively the symmetry, clamping structure 3 is including installing stand 301 on base 1, the inboard of stand 301 is equipped with U type groove 302, the top and the front side of stand 301 all are equipped with clamp plate 303, clamp plate 303 is rotatable to be installed on stand 301, clamp plate 303 passes through rotatable the installing on stand 301 of screw promptly, the clamp plate 303 at top is used for spacing 6 top structures of work piece, the clamp plate 303 of front side is used for spacing 6 work pieces of card in U type groove 302, base 1's middle part still is equipped with crossbeam dog 4.

When the four limit stops 2 are installed on the base 1, the left limit stop 2 and the right limit stop 2 are kept on the same transverse axis, and the front limit stop 2 and the rear limit stop 2 are kept on the same longitudinal axis; upright 301 remains perpendicular to base 1, with both uprights 301 on the same transverse axis. The limit stop 2 and the upright column 301 are respectively installed on the base 1 through bolts.

The four limit stop blocks 2 respectively limit the four corners of the bottom of the workpiece 6; the clamping structure 3 limits the left side and the right side of the workpiece 6; thereby ensuring that the workpiece 6 is just inside the welding tool.

In order to take out the welded workpiece 6 conveniently, the bottom plate is provided with a material taking hole 5 for taking out the workpiece 6.

During operation, firstly, the materials of the workpiece 6 are sequentially placed into corresponding positions of the tool, then the 4 pressing plates 303 are rotated by 90 degrees to tightly press the workpiece 6, welding is started, the pressing plates 303 are loosened after welding is completed, and the workpiece 6 is taken out.

Other technical features than those described in the specification are known to those skilled in the art.
