Cross-shaped plate deformation simple measuring apparatus

The utility model relates to a cross-shaped plate deformation simple measuring apparatus which mainly measures plate deformation generated in a welding process. The cross-shaped plate deformation simple measuring apparatus comprises base plates, guide rails, a sliding block, and a scale ruler and is characterized in that the base plates are fixedly connected with the guide rails; a hole slot is disposed on the top of each guide rail; scales are marked on a side of each hole slot; both ends of the sliding block are equipped with bosses capable of sliding along the guide rails in a reciprocating manner; the sliding block is connected with the guide rails; the scale ruler and an arc hole slot on the middle of the sliding block are both marked with scales; the scale ruler may move horizontally along the arc hole slot on the sliding block and vertically to the sliding block; and the scale ruler is connected with the sliding block. The cross-shaped plate deformation simple measuring apparatus is simple in structure and easy to operate, flexibly and conveniently measures plate deformation caused by welding, saves testing time, and greatly improves testing efficiency.
