Abstract
The invention discloses a patching tool for puttying a front edge and a rear edge of a blade. The patching tool is used for patching step-like shortcomings of rough and uneven surfaces of cured reinforced layers on the front edge and the rear edge of a reinforced wind power blade. The patching tool provided by the invention mainly comprises an arc plate (4), connection blocks (6), an upper handle (1), a lower handle (2), a handle shaft (3) and fixing nuts (5), wherein the upper handle (1) and the lower handle (2) are fixedly connected to the connection blocks (6) at the upper end and the lower end of the arc plate (4) through the fixing nuts (5); the upper handle and the lower handle can rotate around the handle shaft (3), so that the arc plate (4) is driven to be open or closed, the shape of the arc plate (4) is changed along with the change of wing-shaped arc lines on sections of the front edge and the rear edge of the blade, and the aim of patching along with the front edge or the rear edge of the blade is fulfilled. The patching tool disclosed by the invention is uniform in puttying, reduces the working amount of polishing, improves the working environment of a workshop and can well meet a requirement on the pneumatic appearance of the wind power blade.
Description
Technical field
The invention belongs to nonmetallic composite machine-shaping technical field, relate generally to the Puttying of a kind of blade front and rear edge with repairing the type instrument.
Background technology
After the pressure face of large-scale wind electricity blade and suction surface are bonding by adhesive, need strengthen moulding in the leading edge of blade shell outside, the position of trailing edge matched moulds seam, reinforcement material is selected resin and glass fabric for use, and forming method adopts hand to stick with paste and the mode of perfusion is carried out.After leading edge after the reinforcement moulding, the enhancement Layer of trailing edge solidify, can produce scraggly step-like defective on the surface, can not satisfy the requirement of wind electricity blade outward appearance profile, for satisfying the required aerodynamic configuration of wind electricity blade, need repair type by the Puttying of blade front and rear edge to the scraggly step-like defective that produces on the wind electricity blade.At present, both at home and abroad when the scraggly step-like defective of handling that wind electricity blade produces, generally adopt scraper plate to carry out being coated with the mode of scraping and repairing type by hand.Thisly repair the type method not only to be coated with the putty of scraping thicker, and the putty layer became uneven is even, especially after putty solidifies, to follow-up polishing workload is increased, and dust increases severe contamination workshop condition, harm health of human body during polishing.The instrument of the open or blade front and rear edge Puttying used of other technical field in the prior art, for example: be coated with to scrape exterior wall or be coated with and scrape on the automobile case used being coated with of putty and scrape utensil, they have a common ground to be, can play well to be coated with the effect of scraping to the body surface of surfacing unanimity, but can't implement be coated with the type of repairing of scraping to the body surface that cambered surface changes.
Summary of the invention
In view of existing practical problem in the prior art, for the leading edge, the trailing edge that solve the wind electricity blade hull outside are strengthening after the moulding existing defective being repaiied the problem that exists in the type, the inventor proposed a kind of can be with the variation of vane airfoil profile camber line to the type of the repairing instrument of blade front and rear edge Puttying, and can make that to be coated with the putty of scraping even, significantly reduced the polishing workload, reduce the Dust Capacity in the polishing, obviously improved working environment.For achieving the above object, the concrete technical scheme that the present invention takes is: the Puttying of a kind of blade front and rear edge mainly is to be made of arc, contiguous block, upper handle, lower handle, Handle axis and hold-down nut with repairing the type instrument; Wherein arc adopts spring steel plate processing to manufacture, two ends are welded with contiguous block on the arc, upper handle and lower handle are fixedly connected on arc up and down on the contiguous block at two ends by hold-down nut, can make upper handle and the thorny arbor rotation of lower handle by Handle axis, the drive arc opens or is closed, realize that arc can change with the aerofoil profile camber line on wind-powered electricity generation blade inlet edge, the trailing edge profile, reach the purpose that type is repaiied in the Puttying of blade front and rear edge.The Puttying of described a kind of blade front and rear edge is with repairing the type instrument, and wherein the length dimension of camber plate is 700mm; Width dimensions is 50mm, and gauge is 5mm.
A kind of blade front and rear edge of the present invention Puttying is with repairing the type instrument, simple in structure, easy to operate, solved existing deficiency in the prior art, make that to be coated with the putty of scraping even, and satisfy the requirement of wind electricity blade aerodynamic configuration, significantly reduce the polishing workload, reduced the workshop dust, improved working environment.
Description of drawings
Fig. 1 is that type tool construction schematic diagram is repaiied in blade front and rear edge of the present invention Puttying.
Among the figure: 1, upper handle; 2, lower handle; 3, Handle axis; 4, arc; 5, hold-down nut; 6, contiguous block.
The specific embodiment
It is as follows to provide the specific embodiment of the present invention below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of blade front and rear edge of the present invention Puttying mainly is made of arc 4, contiguous block 6, upper handle 1, lower handle 2, Handle axis 3, hold-down nut 5 with repairing the type instrument; Arc 4 adopts spring steel plate processing to manufacture, and two ends are welded with contiguous block 6 on the arc 4.Upper handle 1 and lower handle 2 are fixedly connected on by hold-down nut 5 on the contiguous block 6 at two ends up and down of arc 4, by Handle axis 3 upper handle 1, lower handle 2 thorny arbors 3 are rotated, drive arc 4 opens or is closed, arc 4 can be changed with the aerofoil profile camber line on wind-powered electricity generation blade inlet edge, the trailing edge profile change arc, in order to can be close on wind electricity blade leading edge or the trailing edge.Reach the purpose that type is repaiied in the Puttying of blade front and rear edge.
When repairing type, at first the leading edge of wind electricity blade housing, the zone that the trailing edge outer surface need be strengthened are strengthened handling, use scraper plate to carry out the Puttying of preliminary blade front and rear edge on the reinforced region surface, then blade front and rear edge of the present invention Puttying being repaiied the arc 4 of type instrument is close on the leading edge or trailing edge of wind electricity blade, with the hands catch upper handle 1 and lower handle 2, be close to the wind electricity blade housing simultaneously and move to blade tip.In moving process, apply strength gradually, make arc 4 be close to blade shell, unnecessary putty is scraped, form smooth outer surface.
