Description

Technical Field

[0001] The utility model relates to the technical field of laminated wood board production, in particular to a clamping tool for processing laminated wood boards. Background Art

[0002] In the prior art, laminated wood boards are needed in more and more fields. Electrical laminated wood boards are widely used as insulating and supporting materials in transformers and mutual inductors. They can replace steel structures and insulating components such as epoxy paperboard in transformers and mutual inductors, reduce the volume of transformers and mutual inductors, and reduce costs. Therefore, they are increasingly valued by transformer manufacturers. Electrical laminated wood boards are made by hot pressing multiple wood boards, and need to go through processes such as deburring and polishing to achieve the production and processing of laminated wood boards. During the production and processing, there will be a lot of burrs on the sides after cutting, so the sides need to be processed. However, when processing, it is necessary to first position the sides and the upper and lower surfaces. However, most existing equipment is only suitable for processing laminated wood boards of the same thickness. When processing the sides of laminated wood boards of different thicknesses, they need to be repositioned, and the operation is relatively cumbersome.

[0003] The Chinese utility model patent with application number: 202120344114.3 discloses a side processing device for laminated wood processing, including a rectangular plate, a grinding plate fixedly installed on the left side wall of the rectangular plate, a handle fixedly installed on the right side wall of the rectangular plate, and a fixed plate symmetrically fixedly installed on the upper and lower side walls of the rectangular plate. The outer side walls of the fixed plate are fixedly installed with electric push rods, and the electric push rods are connected to an external power supply through a wire. The output ends of the electric push rods are fixedly installed with limit plates, and the inner side walls of the limit plates are provided with rectangular grooves, and the inner side walls of the rectangular grooves are fixedly installed with fixed shafts, and the outer side walls of the fixed shafts are sleeved with rollers. However, this side processing device for laminated wood processing can only position and clamp a single side of the laminated wood board, and its clamping stability is poor, and it is impossible to adjust the clamping angle according to the actual processing conditions and processing requirements. The processing flexibility is poor, and the clamping speed is slow, which affects the processing progress. Utility Model Content
