Description

Technical Field

[0001] The utility model relates to the technical field of clamping, in particular to a clamping tool suitable for a spring steel plate of a grate cooler. Background Art

[0002] The spring plate assembly of the grate cooler is usually composed of multiple elastic steel plates, sandwich plates and four plywoods. During assembly, it is required to be clamped tightly and fit tightly. The spring plate module is composed of multiple spring plates stacked together. The thickness of a single spring plate is generally 1mm. Since a single spring plate is thin and has low rigidity, it will deform during clamping. In addition, additional tension needs to be applied to the spring plate during the assembly process. Since the four plywoods have a certain curvature at the edges, there will be deviations during manual positioning, resulting in inaccurate positioning and deformation of the spring plate when assembling the plywood and the spring plate module. Therefore, various errors often occur during manual assembly, resulting in non-compliance with the use requirements. Utility Model Content
