As manufacturing industries continue to develop, demands for manufacturing accuracy are becoming higher nowadays. In the automobile manufacturing industry, how to weld the wheel cover plate has higher requirements on the stability of the installation surface, the stability of the embedded nail, the welding position of the embedded nail and the like.
For example, there is patent application No. 201910163255.2, which discloses a positioning welding tool for nail-implanting cover plate assembly of right front wheel cover of automobile, comprising a welding support platform and at least one group of supporting and clamping mechanisms arranged above the welding support platform along the length direction of the cover plate assembly, wherein the supporting and clamping mechanisms support and fix the cover plate assembly, and the cover plate assembly suspension is arranged above the welding machine support platform; the support clamping mechanisms respectively comprise a fixed support mechanism and a movable clamping mechanism, the fixed support mechanisms are arranged on the welding support platform, the fixed support mechanisms support the cover plate assembly, the movable clamping mechanisms are arranged adjacent to the fixed support mechanisms, the movable ends of the movable clamping mechanisms are positioned above the cover plate assembly, and the movable ends of the movable clamping mechanisms of each group are clamped or deviated from the cover plate assembly on the corresponding fixed support mechanism; the fixed supporting mechanism is supported on the inner side surface of each attaching surface M of the cover plate assembly, and the movable end of the movable clamping mechanism correspondingly presses and covers the outer side surface of each attaching surface M.
The nail cover plate assembly fixed-position welding frock is planted to front wheel cover on the right side of car that above-mentioned patent discloses fixes the cover plate assembly centre gripping on fixed support mechanism through movable fixture, reduces the diffusion of stress in the welding, reduces the deformation region. It does play a role in ensuring the accuracy of the welding position, but as far as welding is concerned, it still relies entirely on an external welding torch (pressure torch or lift torch) to perform welding. Thus, the nail needs to be placed and aligned for many times when welding one cover plate assembly (the point P in the attached figure 1 of the specification is the place where each nail is placed and aligned). Therefore, it is not very convenient in soldering.
Of course, there is also application number 201420207287.0 at present to disclose a kind of planting nail spot welding anchor clamps, it includes the anchor clamps body, electrically conductive clamp splice, centre gripping subassembly, copper sheathing installation piece and suit plant the nail and rather than the copper sheathing of electric contact, the centre gripping subassembly articulates on the anchor clamps body, copper sheathing installation piece install on the anchor clamps body, electrically conductive clamp splice fixed connection on the centre gripping subassembly to be provided with the mounting hole on the electrically conductive clamp splice, the copper sheathing installation piece has the planting nail locating hole, and the copper sheathing suit is on the copper sheathing installation piece, the copper sheathing cooperatees so that the nail is planted in the location with planting the nail locating hole to the installation face of installation copper sheathing is parallel with electrically conductive clamp splice on the copper sheathing installation piece, leaves the solder joint interval between the top of copper sheathing and the electrically conductive clamp splice, electrically conductive clamp splice and copper sheathing pass through electric wire and planting nail electromechanical nature connection respectively. Although it can assist welding, improve welding efficiency. But it is not directly suitable for the automobile right front wheel cover nail-planting cover plate assembly positioning welding tool, and no one can use it on the automobile right front wheel cover nail-planting cover plate assembly positioning welding tool.
