Example (b): a welding tool, see figure 1, comprises a workbench 1, a clamping device 2 arranged at the top end of the workbench 1 and a positioning plate 3 fixed on one side of the workbench 1.

The surface of the workbench 1 is provided with a plurality of strip holes 11, and the strip holes 11 can be along the length direction of the workbench 1 and also can be along the width direction of the strip holes 11. At least 3 of the strip holes 11 form a group (the distance between two adjacent strip holes 11 is the same), and a plurality of groups of strip holes 11 are arranged on the workbench 1. The holding device 2 is fixed to the elongated hole 11.

The side of rectangular hole 11 is fixed with backup pad 12 perpendicularly, and backup pad 12 supplies to treat that welded part (generally for the sheet metal component) places for there is the clearance between part and the workstation, prevents to take place the adhesion between welded in-process part and the workstation 1. A right-angle plate 121 is fixed on one side of the supporting plate 12, one side of the right-angle plate 121 close to the workbench 1 is perpendicular to the workbench 1, and one side of the right-angle plate 121 close to the supporting plate 12 is perpendicular to the supporting plate 12. The right-angle plate 121 can increase the connection strength of the support plate 12 and reduce the inclination of the support plate 12. The top of the supporting plate 12 is further provided with a groove 122, and the groove 122 is used for placing cylindrical parts, so that the placing stability of the cylindrical parts is improved.

Referring to fig. 1 and 2, the clamping device 2 includes a fixing block 21 placed on the table 1 and an elbow clip 22 fixed to the top end of the fixing block 21.

The middle of the bottom end of the fixed block 21 is fixed with a positioning block 211, and the two sides of the bottom end of the fixed block 21 are fixed with connecting blocks 212. The positioning block 211 can be inserted into the elongated hole 11 and position the two-side connection block 212. The connecting block 212 is provided with a bolt 213, and one end of the bolt 213 passes through the connecting block 212 and the elongated hole 11 and is then screwed with a nut 214 to fix the connecting block 212, so that the fixing block 21 is fixed on the workbench 1. The distance from the positioning block 211 to the bolt 213 is the same as the distance from the adjacent two elongated holes 11. In the process of inserting the positioning block 211 into the elongated hole 11, at least one elongated hole 11 is reserved outside the elongated hole 11 into which the positioning block 211 is inserted, through which the bolt 213 passes.

A pressing rod 221 is connected to one end of the elbow clamp 22 close to the raw material, a pressing head 222 is fixed to one end of the pressing rod 221 close to the raw material, and the pressing head 222 is made of soft materials (such as rubber).

The elbow clamp 22 is designed according to the principle of a double-rocker mechanism in a planar four-bar mechanism, and the basic structure of the elbow clamp is composed of four components, namely a connecting bar, a frame, two side links and the like. When the three points of the two hinged points of the connecting rod and the side link and the hinged point of one of the side links and the frame are in the same straight line, the mechanism is in a dead point position. At this time, the workpiece to be pressed cannot release the ram 222 regardless of the reaction force.

The using method comprises the following steps: be provided with a plurality of groups rectangular hole 11 on the workstation 1, adjust the position and the quantity of placing clamping device 2 according to actual processing part shape and placing for clamping device 2 can carry out stable centre gripping to the part, realizes placing of different work pieces, and makes things convenient for the welding in later stage.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
