Abstract

The utility model relates to a tool is used in work piece welding, tool that the in -process that welds front shroud and the back shroud of impeller at the work pieces such as blade with the impeller of specifically saying so used. Its characteristics are including the base, are fixed with the backup pad on the base, and the one end of backup pad is outwardly directed from one side of base. The backup pad coats and is stamped electrically conductive copper, has electric welding head on the electrically conductive copper that the overhanging terminal pair of backup pad was answered. Easily take out after using on front shroud that this tool welded the work pieces such as blade of impeller and the back shroud, and can avoid appearing skidding in welding process, the solder joint is to inaccurate problem.

Description

A kind of workpiece welding tool

Technical field

This utility model relates to a kind of welding aid, specifically at the tool being welded in the front shroud of impeller and the process of back shroud to use workpiece such as the blades of impeller。

Background technology

Manufacturing field at impeller to both know about, the workpiece such as the blade in impeller is connected with front shroud and the back shroud of impeller by the mode welded。At present, the welding method used in industry is: first front shroud and back shroud to impeller position；Then, it would be desirable to the workpiece such as the blade of the impeller of welding are placed into the ad-hoc location between front shroud and back shroud；Then, between the front shroud and back shroud at the workpiece places such as blade, it is encased inside copper billet, is used for supporting and conducting electricity；Afterwards, compress front shroud and back shroud, utilize welding tool to be welded on front shroud and back shroud by the workpiece such as blade。Adopting after on front shroud and back shroud that the workpiece such as the blade of impeller are welded to impeller in this way, the copper billet being encased inside easily is stuck between front shroud and back shroud, is not easily taken out。Simultaneously as the intensity of copper is relatively low, easily occur bending and deformation, so the problem of skidding, solder joint misalignment easily occurs in welding process。

Utility model content

The technical problems to be solved in the utility model is to provide a kind of workpiece welding tool, use this tool that the workpiece such as the blade of impeller are welded to the rear easily taking-up with on back shroud of the front shroud of impeller and the problem that can avoid the occurrence of skidding, solder joint misalignment in welding process。

For solving the problems referred to above, it is provided that techniques below scheme:

The feature of workpiece welding tool of the present utility model is to include base, and base is fixed with gripper shoe, and one end of gripper shoe is protruding from the side of base。Described gripper shoe is coated with conductive copper plate, the conductive copper plate that the overhanging end of gripper shoe is corresponding has electric welding head。

Wherein, described gripper shoe is iron plate。

Take above scheme, have the advantage that

Owing to workpiece welding tool of the present utility model includes base, base has gripper shoe, gripper shoe has conductive copper plate, conductive copper plate has electric welding head。When using this tool to be welded between the front shroud of impeller and bonnet by the workpiece such as the blade of impeller, first front shroud and back shroud are positioned；Then, it would be desirable to the workpiece such as the blade of welding are placed into the ad-hoc location between front shroud and back shroud；Then, being tucked into by the overhanging end of gripper shoe between front shroud corresponding to the workpiece such as blade and back shroud, electricity consumption soldering tip needs the position of welding against workpiece such as blades；Afterwards, compress forward and backward cover plate, utilize welding set to be welded on front shroud and back shroud by the workpiece such as blade。After adopting this tool to be welded on front shroud and back shroud by workpiece such as the blades of impeller, base is pulled to be taken out between front shroud and back shroud by tool。Meanwhile, utilize gripper shoe to support conductive copper plate so that conductive copper plate is unlikely to deform bending, thus avoid occur because of conductive copper plate bending skidding, solder joint misalignment problem。

Accompanying drawing explanation

Fig. 1 is the structural representation of workpiece welding tool of the present utility model；

Fig. 2 is workpiece welding tool of the present utility model structural representation in a state of use。

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further detail。

As it is shown in figure 1, workpiece welding tool of the present utility model includes base 1, base 1 being fixed with gripper shoe 2, one end of gripper shoe 2 is protruding from the side of base 1, and this gripper shoe 2 is iron plate。Described gripper shoe 2 is coated with conductive copper plate 3, the conductive copper plate 3 that the overhanging end of gripper shoe 2 is corresponding has electric welding 4。

As in figure 2 it is shown, when using this tool that blade 5 workpiece such as grade of impeller is welded to front shroud 6 and the back shroud 7 of impeller, first front shroud 6 and back shroud 7 are positioned。Then, it would be desirable to blade 5 workpiece such as grade of welding is placed into the ad-hoc location between front shroud 6 and back shroud 7。Then, being tucked into by the overhanging end of gripper shoe 2 between front shroud 6 corresponding to blade 5 workpiece such as grade and back shroud 7, electricity consumption soldering tip 4 needs the position of welding against blade 5 workpiece such as grade。Afterwards, compress front shroud 6 and back shroud 7, utilize welding set 8 to be welded on front shroud 6 and back shroud 7 by blade 5 workpiece such as grade。
