The utility model has the advantages that: the flange is ensured not to move up and down in the welding process, thereby ensuring the yield of the welding process.
Description
Technical Field
The utility model relates to a compressing positioning mechanism before automobile exhaust system flange welding process belongs to the supplementary closing device technical field of welding.
Background
The flange of the automobile exhaust system needs to be positioned on a welding workbench before welding for ensuring the accuracy of a welding position, after positioning, the flange cannot slide transversely relative to the welding workbench, but the flange cannot be tightly attached to the welding workbench due to the fact that the flange does not have a constraint force action in the vertical direction, and the movement of the flange in the vertical direction can influence the welding accuracy, so that more defective products are caused.
SUMMERY OF THE UTILITY MODEL
For solving the defect that prior art exists, the utility model aims at providing a will treat that welded flange compresses tightly on welding the workstation to guarantee welding precision's automobile exhaust system welded flange bulldoze tight mechanism in advance.
The technical scheme of the utility model is that: the utility model provides a tight mechanism bulldozes in advance of automobile exhaust system welded flange, the riser is connected to the upper fixed plate bottom, installs double acting cylinder on the riser, double acting cylinder's piston rod runs through the riser, and the piston rod articulates the connecting rod, and the connecting rod links to each other with the U-shaped briquetting, and the fixed block is fixed on the riser, and connecting rod and fixed block are articulated respectively at the connecting block both ends, and double acting cylinder end connection cylinder frame, fixed axle are installed on the cylinder frame, and the articulated rocking arm of fixed axle removes axle one end and links to each other with the piston rod, and the pivot swing joint.
And a rib plate is arranged at the joint of the upper fixing plate and the vertical plate.
The end part of the rotating arm is provided with a handle.
And a pressing block is arranged at the end part of the U-shaped pressing block.
The utility model has the advantages that: through pulling the handle, promote double-acting cylinder's piston rod and remove, the piston rod drives the U-shaped briquetting and rotates, and the U-shaped briquetting drives the compact heap of tip and treats welding flange direction along arc orbit below and remove, and the compact heap contacts the flange and compresses tightly, then the cylinder moves and carries out pneumatic secondary to the flange and compress tightly, makes the compact heap not take place the skew, compresses tightly on the flange all the time, guarantees that the flange can not reciprocate in the welding process to guarantee welding process's yield.
