The welding workbench is used for clamping and fixing the workpiece so as to facilitate the subsequent matching of the welding robot for welding the workpiece. Firstly, a workpiece is placed on a rotatable roll-over stand of a welding workbench, and then the workpiece is fixed on the roll-over stand through a locking bolt, a pressing plate and a quick clamping tool. When the workpiece is welded, the turnover frame needs to be turned over so as to enable the turnover frame to be in a horizontal or vertical state and keep the position of the turnover frame.
For example, in a welding table disclosed in chinese patent No. 201721711639.6, a positioning hole is formed in an edge of a roll-over stand, and a positioning pin that is axially movable is provided at a fixed position (a fixed frame), and an axis of the positioning pin is parallel to or perpendicular to an axis of rotation of the roll-over stand, so that the positioning pin is inserted into the positioning hole to maintain a position of the roll-over stand.
The above-mentioned solution for maintaining the position of the roll-over stand has the following disadvantages: if the difference between the outer diameter of the positioning pin and the inner diameter of the positioning hole is small, the positioning pin cannot be inserted into the positioning hole; if the difference between the outer diameter of the positioning pin and the inner diameter of the positioning hole is large, a gap exists between the positioning pin and the positioning pin, the overturning frame has the possibility of overturning in a small range, and the welding effect of subsequent workpieces can be influenced; and if the roll-over stand is bigger and heavier, the positioning pin will have the possibility of bending, and the position of the roll-over stand will deviate, influencing the welding effect of the workpiece.
