Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 3, a lifting type positioning and compressing device comprises a bottom supporting and compressing device 01, a top adsorbing and positioning and compressing device 02 and a bottom lifting and sliding device 03. The device is suitable for welding large plane plates, cross beams and small pieces, and is suitable for areas such as front floors, rear floors, top covers, battery panels and the like of white car bodies.

Working principle: firstly, placing a panel on a bottom supporting and pressing device 01, and pressing a button for clamping after the panel is positioned and exits from a safe distance; then pick up crossbeam and smallclothes and make it adsorb the location on top adsorb location closing device 02, personnel press button top and adsorb closing device and slide down after withdrawing from the safe distance, reach with setting for the position, make crossbeam and smallclothes compress tightly with the panel laminating. Finally, a person picks up welding spots at welding lap positions of the welding gun, after the welding gun is replaced, the top of the button is pressed to adsorb, position and press the pressing device 02 to return to the original position, the bottom supporting and pressing device 01 is opened, the bottom lifting and sliding device 03 is lifted, and the person pulls out a plate to take a workpiece to flow to the next station. When the stations continuously operate, the panel can be firstly placed on the bottom lifting sliding device 03, after the panel is pushed to a preset position, after the panel exits from the preset position, a button is pressed, and the lifting position falls down to the specified position; the above-described cycle may be satisfactory for the welding process.
