Embodiment 1

[0030] A leading edge automatic trimming device for fan blades, comprising a support platform 8 for laterally supporting the fan blade a and a base 9 for fixing the support platform 8 to the ground, above the support platform 8 there is a matching support The platform 8 is used to position the upper positioning unit of the fan blade a, and the upper end of the base 9 is laid with a trolley track 12 on the side close to the leading edge a1 of the blade, and the trolley track 12 is provided with a front edge repair mechanism that can drive independently;

[0031] In this example, if Figure 1-2 As shown, the cross-section of the fan blade a shows that the fan blade a includes two sheets and an adhesive layer a3 that is located between the two sheets and bonds the two sheets. After the fan blade a is bonded and formed, the adhesive The junction layer a3 will protrude on the leading edge a1 and the trailing edge a2 of the fan blade a after the mold is opened, and it needs to be re...

Embodiment 2

[0039] The difference between this embodiment and embodiment 1 is that, as Figure 2-3 As shown, the upper positioning unit includes an underpackage walking track 3 fixed on the crossbeam of the workshop, and a self-propelled linear walking vehicle 2 is installed through the walking wheels 4 in the walking track 3. The lower end of the linear walking vehicle 2 is vertically A lifting cylinder 1 is installed, and the telescopic end of the lifting cylinder 1 is connected with a horizontally arranged installation platform 6 through a rotating seat 5. The lower end of the installation platform 6 is provided with a positioning seat 7 for positioning the fan blade a after cooperating with the support platform 8, and the lifting cylinder 1 A pressure sensor II is installed on the telescopic end of the motor, and the movement of the positioning seat 7 can be effectively driven by the walking of the linear traveling vehicle 2 on the walking track 3, and the segmented blade leading edge ...

Abstract

The invention relates to the technical field of fan blade manufacturing, provides automatic modification equipment for the front edge of a fan blade, and aims to achieve surface flatness and arc degree modification of the front edge of a molded fan blade when the front edge of the fan blade is used as the foremost end in contact with wind power. The automatic modification equipment comprises a supporting table used for transversely supporting the fan blade, an upper positioning unit used for being matched with the supporting table to position the fan blade is arranged above the supporting table, a trolley track is laid on the side, close to the front edge of the blade, of the upper end of a base, a front edge modification mechanism is arranged on the trolley track, the automatic front edge modification mechanism comprises a frame body which autonomously runs on the trolley track through trolley body walking wheels, and the frame body is provided with a front edge trimming mechanism, a front edge polishing mechanism arranged behind the front edge trimming mechanism and a distance adjusting unit arranged below the front edge trimming mechanism and the front edge polishing mechanism. The automatic modification equipment is particularly suitable for automatic modification of the fan blade, and has high social use value and application prospects.

Description

technical field [0001] The invention relates to the technical field of fan blade manufacturing, in particular to a front edge automatic trimming device of a fan blade. Background technique [0002] Wind energy is a clean and pollution-free renewable energy source. It has been used by people for a long time, mainly through windmills to pump water and grind flour. People are interested in how to use wind to generate electricity. Using wind power to generate electricity is very environmentally friendly, and wind energy The potential is huge, so it is increasingly valued by countries all over the world. [0003] Fan blades generally have a length of more than tens of meters, and are mostly made of lightweight composite materials. The speed of the blade tip of a fan in normal operation can reach 60-110m / s. , and the front edge of the fan blade is the front end of the wind force, and its surface flatness and curvature are related to the aerodynamic performance of the fan blade. ...
