Description

Technical Field

[0001] The utility model relates to a stable pultruded plate grinding device, belonging to the technical field of grinding. Background Art

[0002] As the exhaustion schedule of traditional fossil energy such as coal, oil and natural gas is approaching, the development and utilization of wind energy has attracted more and more attention and has become one of the most commercially promising projects in the energy field. It is currently developing rapidly at home and abroad. Wind power generation is mainly achieved through wind turbines, and wind turbine blades are the core components of wind turbines. The wind power drives the wind turbine blades to rotate to drive the generator to generate current.

[0003] Wind turbine blades are usually made of a windward shell and a leeward shell bonded together. The shell consists of a main shell and various components. The main beam is the most important component of the blade and is the main load-bearing structure of the blade, and its manufacturing process also has high requirements. Previously, most manufacturers used the vacuum infusion process to produce the main beam, that is, laying layers on the main beam mold, vacuum bag sealing, vacuum introduction of resin, and curing molding. However, as the blade models become longer and longer, the main beam layers become thicker and thicker, the infusion process becomes more and more difficult, and the quality becomes more and more unstable. Pultruded sheet has become the mainstream molding process for large blade main beams due to its series of excellent mechanical properties and process performance. It cuts and grinds the formed pultruded sheet into a specific length and shape, lays, stacks and tightens the sheet according to the designed process, and then hoists it to the corresponding position of the main beam in the shell and infuses it into an integral part with the shell.

[0004] When grinding the top and bottom of the pultruded sheet, the prior art usually adopts the following method: Figure 4 The grinding device shown drives the grinding disc 200 to rotate by the grinding motor 100 to achieve the grinding of the pultruded plate. When the rotating motor 300 is started, the rotating shaft 500 is driven to rotate by the reducer 400. The rotation of the rotating shaft 500 drives the mounting base 600 connected to the grinding motor 100 to rotate, thereby achieving the adjustment of the angle of the grinding disc 200. When the movable part of the linear module 800 is driven to rise and fall by the lifting motor 700, the movable part of the linear module 800 drives the reducer 400 connected thereto to rise and fall synchronously, thereby achieving the lifting and lowering of the grinding disc 200. However, during the grinding process, the grinding disc 200 will be subjected to a reverse force perpendicular to the grinding surface. The distance between the force position of the grinding disc 200 and the linear module 800 is long, that is, the force arm is long, which can easily cause the grinding disc 200 to jump, affecting the stability of the grinding of the grinding disc 200.

[0005] Therefore, a stable pultruded plate grinding device is needed to improve the stability of grinding. Utility Model Content
