Said through hole one end inboard is provided with annular projection, and copper sheathing inserts behind the key seat front end and arrives to annular projection and promptly stop like this, thereby copper sheathing can firmly be inserted in the key seat, displacement can not take place because of the plug of alignment pin or drops out.
Described installing hole has four, and wherein two installing holes supply fastening bolt to pass, and two other installing hole supplies holding pin to pass, and these four installing holes are used for mechanism is fixed on anchor clamps.When mechanism uses, pass two installing holes on the key seat, mechanism is fixed on the anchor clamps with two fastening bolts; Pass two other installing hole on the key seat with two holding pins again, mechanism is positioned on the anchor clamps, holding pin and corresponding installing hole interference fit are to guarantee mechanism's secure on anchor clamps.
After said alignment pin inserted key seat, front end inserted in the locating hole of workpiece, realizes the location to workpiece.
A described pin Leading end chamfer makes things convenient for the plug of alignment pin in key seat, the interference between minimizing and the key seat.
Described pin middle part is provided with spacing round platform, and spacing round platform external diameter is greater than the diameter of section of key seat through hole.After alignment pin inserted the through hole on the key seat like this, alignment pin promptly stopped to continue to insert after spacing round platform arrives to key seat.
Described pin tail surface is provided with decorative pattern, conveniently grips alignment pin.
The utility model is simple in structure, is used in small space, welding work pieces being positioned and supporting.During use, earlier workpiece is placed in clamping on the anchor clamps; The end that the key seat of mechanism is provided with installing hole passes two installing holes near anchor clamps with two trip bolts, and mechanism is fixed in the screwed hole on the anchor clamps, passes two other installing hole with two holding pins simultaneously, and mechanism is positioned on the anchor clamps; Then alignment pin is inserted the copper sheathing endoporus of key seat, the alignment pin front end passes in the locating hole of copper sheathing insertion workpiece; Alignment pin promptly stopped to continue to insert after spacing round platform on the alignment pin arrived to key seat, thereby realized the location to workpiece.
Adopt the utility model, have following beneficial effect: (1) is simple and practical, and is with low cost; (2) take up room for a short time, easy to operate, time saving and energy saving, do not influence weld job; (3) can the welding work pieces in the small space be positioned and support, effectively avoid the solder joint distortion or weld unreal phenomenon, improve welding efficiency and welding product quality.
