Description

Technical Field

[0001] The utility model relates to the technical field of heat insulation board processing equipment, in particular to a positioning structure for processing a refractory fiber composite heat insulation board. Background Art

[0002] Refractory fiber is a fibrous refractory material and a highly efficient thermal insulation material. It has the characteristics of general fibers (such as softness and high strength), and can be processed into various papers, tapes, cords, felts and blankets, etc. It also has the properties of high temperature resistance, corrosion resistance and oxidation resistance that ordinary fibers do not have, overcoming the brittleness of general refractory materials. At the same time, it has a very significant energy-saving effect. As a refractory and thermal insulation material, it has been widely used in metallurgy, chemical industry, machinery, building materials, shipbuilding, aviation, aerospace and other industrial sectors.

[0003] Chinese patent CN213796784U discloses a positioning device for heat insulation board processing, including a workbench, an L-shaped positioning plate, a sliding groove assembly, a clamping assembly and a slider, the sliding groove assembly includes a first sliding groove, a second sliding groove, a third sliding groove, a fourth sliding groove, a fifth sliding groove and a sixth sliding groove, the clamping assembly includes a positioning plate, a fixing plate, a pressing plate, a connecting block, a locking screw, an adjusting screw and a cushion. In the utility model, by setting a clamping assembly and a plurality of sliding grooves, it is used to flexibly clamp heat insulation boards of different lengths, so as to realize effective positioning of the heat insulation board surface. The distance between the fixed plate and the pressing plate is continuously adjusted, which is suitable for positioning insulation boards of different thicknesses. At the same time, an L-shaped positioning plate is provided to realize the positioning of the side walls of the insulation boards. The insulation boards can be positioned in multiple directions through the coordinated action of the sliding groove assembly, the clamping assembly and the L-shaped positioning plate to prevent the insulation boards from shaking or shifting during processing, thereby improving the processing quality of the insulation boards. Currently, the clamping of the boards is mostly to press the board surfaces, while when processing the side walls of the insulation boards, the insulation boards are prone to move to both sides. When this structure is processed, the boards will shift, resulting in the inability to achieve precise operation of the boards.
