Description
Technical Field
The utility model belongs to the technical field of wind power equipment, concretely relates to flexible clamping device of wind power equipment blade root flange.
Background
The blade is an industry with high certainty, large market capacity and clear profit mode in wind power parts. With the relief of the situation of supply and demand tension, the wind power blade industry will also be changed from a group male mixed battle to several strong battles, and the wind power blade industry in China is undergoing an industrial shuffling and integration. With the expansion of the market scale of the wind power blade, the cost and the selling price are reduced, but the cost reduction speed of an enterprise with the advantages of scale, technology and cost exceeds the selling price reduction speed, and the profit exceeds the average level. Future industry competitive formats require manufacturers to scale up, reduce costs, and retain certain technical advantages.
The wind power blade is connected with the wind power generator set through a connecting bolt at the root part, and the connecting bolt is connected with the root part of the blade through a T-shaped round nut or an embedded bolt sleeve. Must guarantee the accuracy of bolt hole above adding man-hour to the root flange, whether the person can lead to follow-up unable butt joint, present root flange all adopts the structure of concatenation, namely divide into several parts with a circular flange, respectively to several parts processing and transportation, this kind can practice thrift very big cost, but the processing to this kind of root flange needs higher precision, whether the person leads to the hole to be not corresponding when splicing easily, all fix through positioning fixture to this kind of root flange processing fixed mode at present, it is not hard up easily when fixed, lead to the machining precision to reduce.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a flexible clamping device of wind power equipment blade root flange to solve the problem that exists among the background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a wind power equipment blade root flange flexible clamping device which characterized in that: including bottom plate, cylinder, guide arm, guide pin bushing, synchronous board, U-shaped locating rack, movable roller, dorsal part positioning roller and tip positioning roller, the cylinder is fixed one side of bottom plate, the guide arm is two, and the both ends of guide arm are passed through the guide arm support and are fixed on the bottom plate, the guide pin bushing with guide arm sliding connection, synchronous board's both ends with the guide pin bushing rigid coupling, synchronous board's middle part with the piston rod of cylinder is connected, synchronous board's the outside with U-shaped locating rack rigid coupling, movable roller is installed respectively to the both sides of U-shaped mount, dorsal part positioning roller and tip positioning roller are installed on the bottom plate through the gyro wheel support respectively, and movable roller, dorsal part positioning roller and tip positioning roller will treat that the root flange of processing encloses.
Preferably, the number of the back positioning rollers is at least two.
Preferably, a connecting rod is arranged between the U-shaped fixing frame and the synchronous plate, and a spring is sleeved on the connecting rod. The utility model has the advantages that: this device compact structure fixes processing through this device to mosaic structure's blade root flange, and is fixed firm, and then has improved the machining precision, can improve blade root flange quality greatly.
Drawings
Fig. 1 is a top view of the present invention;
fig. 2 is a side view of the present invention.
Detailed Description
The following detailed description of the preferred embodiments of the present invention is provided in connection with the accompanying drawings.
As shown in fig. 1-2, a flexible clamping device for a blade root flange of a wind power device comprises a bottom plate 1, a cylinder 2, a guide rod 3, a guide sleeve 4, a synchronizing plate 5, a U-shaped positioning frame 6, a movable roller 7, a back positioning roller 8 and a tip positioning roller 9, wherein the cylinder is fixed on one side of the bottom plate, the guide rods are two, the two ends of the guide rod are fixed on the bottom plate through guide rod supports 10, the guide sleeve is in sliding connection with the guide rod, the guide sleeve slides left and right on the guide rod, the two ends of the synchronizing plate are fixedly connected with the guide sleeve, the middle of the synchronizing plate is connected with a piston rod of the cylinder, the outside of the synchronizing plate is fixedly connected with the U-shaped positioning frame, the cylinder drives the U-shaped positioning frame to move back and forth, the movable rollers are respectively installed on the two sides of the U-shaped fixing frame, the distance between the two movable rollers ensures that the two sides of an inner side included angle of the blade root flange can be clamped, the back positioning roller and the tip positioning roller are respectively installed on the bottom plate through roller supports, the movable roller, the back positioning roller and the root flange and the two movable rollers extend out of the root flange, and the two movable rollers extend out of the bottom plate.
In order to enable two interactive rollers on the U-shaped fixing frame to always have a clamping force on the flange at the root part, a connecting rod is arranged between the U-shaped fixing frame and the synchronous plate, and a spring 12 is sleeved on the connecting rod. When the air cylinder drives the U-shaped fixing frame to extend outwards, the two movable idler wheels on the U-shaped fixing frame contact with two sides of the inner angle of the root flange, and the spring contracts and always has a thrust force on the root flange.
It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
