Wind-powered electricity generation blade pushes down adjusts structure

Technical Field

The utility model belongs to the technical field of wind-powered electricity generation blade preparation, especially, relate to a wind-powered electricity generation blade pushes down and adjusts structure.

Background

In the production and manufacturing process of the wind power blade, a plurality of structural members with a compressing function are required, for example, in the process of bonding a web plate and a blade shell, in order to ensure a theoretical gap value between the bottom of the web plate and the shell, the web plate needs to be pressed down to adjust the theoretical gap value; in order to ensure the perpendicularity of the web, the web needs to be adjusted in the chordwise direction. The pressing adjusting structure mainly comprises a screw, a nut and a pressing block, and the pressing block cannot rotate along with the screw when the screw is screwed in and out. The existing compression structure has two forms, one is a bearing structure 13 (figure 6), and the other is a universal ball head structure 12 (figure 7). The first bearing structure is relatively expensive in form; the second universal ball head structure is mainly an outsourced finished product, and due to the fact that on-site dust is large, the universal ball head is prone to the phenomena of inflexible rotation and even immobility after being used for a period of time.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a wind-powered electricity generation blade pushes down adjusts structure to adopt among the solution prior art that the bearing arrangement cost is higher, adopt universal bulb structure to appear rotating inflexible problem after using a period easily.

In order to achieve the above purpose, the technical scheme of the utility model is that: a wind power blade pressing adjusting structure comprises a screw, a nut and a pressing block; the screw comprises a threaded section, a cylindrical section, a cylinder and a spherical crown body which are concentrically fixed in sequence, and the nut can be in threaded connection with the threaded section; the diameter of the cylindrical section is smaller than that of the cylinder, the end face of the spherical crown body is fixed with the cylinder, and the diameter of the largest cross section of the spherical crown body in the axial direction does not exceed the diameter of the cylinder; the spherical surface of the spherical crown body is used for driving the pressing block; a stepped hole is formed in the pressing block, and the small-diameter side of the stepped hole is positioned on the outer side of the pressing block; an internal thread is arranged inside the small-diameter side of the stepped hole; the outer part of the column body is provided with an external thread; the column body can be in threaded connection with the internal thread; the diameter of the small diameter side of the stepped hole is larger than that of the cylindrical section, and the diameter of the large diameter side of the stepped hole is larger than that of the cylindrical section; the total thickness between the column and the spherical crown body is smaller than the width of the large-diameter side of the stepped hole.

Further, the total thickness among the cylindrical section, the cylinder and the spherical crown body is larger than the width of the stepped hole.

Further, the height of the spherical cap body is smaller than the diameter of the sphere corresponding to the spherical cap body.

Further, the diameter of the thread section is larger than that of the cylindrical section.

The working principle of the technical scheme is as follows: and welding the nut on the bracket, screwing the thread section of the screw into the nut, and matching the internal thread on the small-diameter side of the stepped hole with the external thread of the column body to screw the column body into the stepped hole until the column body and the spherical cap body are completely screwed into the large-diameter side of the stepped hole. When a product needs to be compressed, the threaded section is rotated, the threaded section moves towards the product in the rotating process, the threaded section sequentially passes through the cylindrical section, the column body and the spherical crown body to apply force to the ship body to press the block, and the product is compressed by the press block.

The beneficial effects of this technical scheme lie in: (1) through the external screw thread on the cylinder and the internal thread threaded connection of shoulder hole path side between screw rod and the briquetting, not only be convenient for assemble and dismantle the clearance dust, the cost of manufacture is low, and the briquetting can not the in-process landing from the screw rod in addition. (2) Because the diameter of the major diameter side of the stepped hole is greater than that of the cylinder, the diameter of the sphere corresponding to the spherical cap body is less than that of the cylinder, and the total thickness between the cylinder and the spherical cap body is less than the width of the major diameter side of the stepped hole, so that the pressing block and the screw rod can move mutually, the pressing block cannot rotate along with the screw rod, the pressing block can also rotate freely in multiple directions, and the pressing effect on a product is better.
