Description

Fan cabin processing tool

Technical Field

The invention relates to processing equipment of a wind driven generator, in particular to a processing tool of a fan engine room.

Background

As shown in fig. 1, in a blower nacelle 1, a bottom surface 1a and a machined surface 1b of the nacelle 1 have a certain angle difference, and are positioned by the bottom surface when in use. The original mode is that a circle of first through holes are processed on the top surface of the tool, the first through holes are arranged opposite to second through holes on the bottom surface of the engine room, then bolts penetrate through the first through holes and then penetrate out of the second through holes, and then the first through holes are connected with the bolts. In this way, in order to fix the position of the nacelle, it is generally necessary to screw at least 4 bolts, which is troublesome, and therefore, improvement is necessary.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides the fan engine room machining tool, and the positioning of the engine room can be completed only by screwing one bolt.

The invention is realized by the following technical scheme: the utility model provides a fan cabin processing frock, includes bottom plate and panel, bottom plate and panel are certain angle, bottom plate and panel pass through the connecting plate and link to each other, and the bottom surface setting in cabin is in on the panel, the bottom surface border in cabin is provided with round second through-hole, be provided with at least three spacing post on the top surface of panel, every spacing post with the bottom surface inner circle in cabin contacts, be provided with a first through-hole on the panel, the bolt passes first through-hole with link to each other with the nut behind the second through-hole. According to the principle that a circle is determined by three points, the position of the engine room can be determined by using three positioning columns, and then a bolt penetrates through the first through hole and the second through hole and is connected with the nut, so that the three positioning columns are always in contact with the inner ring of the bottom surface. Therefore, the positioning of the cabin can be completed, and compared with the prior method that at least three bolts are screwed, the process is greatly simplified.

In the above technical solution, preferably, there are three limiting posts, three of the limiting posts and the bottom surface contact point are located in the same semicircle, and the second through hole communicated with the first through hole is located in the other semicircle. The bolt can be tensioned, and the limit column is ensured to be in close contact with the inner ring of the bottom surface.

In the above technical solution, preferably, the arc lengths between the adjacent limiting columns are the same, and the limiting column located in the middle is arranged opposite to the first through hole with respect to the center of the bottom surface.

In the above technical solution, preferably, the bolt includes a bolt head with magnetism and a bolt column without magnetism, and the bolt is magnetically attracted to the bottom of the panel. Set up like this, the bolt need not all be taken off from the frock, has removed the trouble of workman's installation bolt every time from. Once the bolt is not fixed on the panel, if the first through hole and the second through hole are not aligned, the bolt can be pressed down, and the bolt cannot be clamped. Secondly, if first through-hole and second through-hole have aimed at, also prevent that the bolt post from adsorbing on the second through-hole inner wall, let the second through-hole can't be worn out to the bolt post, lead to the nut to connect the difficulty.

Compared with the prior art, the invention has the beneficial effects that: when the blade is installed at the end part of the fan blade, the protrusion is inserted into the hole at the end part of the blade matched with the protrusion, at this time, the axis of the protrusion is coaxial with the axis of the end part of the blade, and the protrusion is coaxial with the variable pitch disc body, so that the variable pitch disc and the blade can be ensured to be coaxial. Then we rotate certain angle again, until the through-hole that the annular circled is relative with the screw of blade tip, reuse the bolt locking, just so accomplished and become the whole process of oar dish installation on the fan blade, compare with original mounting means, we can ensure to become the oar dish and be in same axis with the fan blade after the installation, let the fan blade more stable when the rotation.

Detailed Description

The invention is described in further detail below with reference to the following detailed description and accompanying drawings:

referring to fig. 2 and 4, the machining tool for the fan engine room comprises a bottom plate 2 and a panel 3, wherein the bottom plate 2 and the panel 3 form a certain angle, the bottom plate 2 and the panel 3 are connected through a connecting plate 4, the bottom surface 1a of the engine room 1 is arranged on the panel 3, a circle of second through holes 11 are formed in the periphery of the bottom surface 1a of the engine room 1, and three limiting columns 5 are arranged on the top surface of the panel 3. Each limiting column is in contact with the inner ring of the bottom surface of the engine room, three contact points of the limiting columns 5 and the bottom surface 1a are located in the same semicircle, the arc lengths between the adjacent limiting columns 5 are the same, and the limiting column located in the middle and the first through hole are arranged opposite to the circle center of the bottom surface.

The panel 3 is provided with a first through hole 31, and the bolt 6 passes through the first through hole 31 and the second through hole 11 and then is connected with the nut 7. The second through hole 11 communicating with the first through hole 31 is located in the other semicircle. The bolt can be tensioned, and the limit column is ensured to be in close contact with the inner ring of the bottom surface.

According to the principle that a circle is determined by three points, the position of the engine room can be determined by using three positioning columns, and then a bolt penetrates through the first through hole and the second through hole and is connected with the nut, so that the three positioning columns are always in contact with the inner ring of the bottom surface. Therefore, the positioning of the cabin can be completed, and compared with the prior method that at least three bolts are screwed, the process is greatly simplified.

The bolt 6 comprises a magnetic bolt 61 head and a non-magnetic bolt column 62, and the bolt 6 is magnetically attracted to the bottom of the panel 3. Set up like this, the bolt need not all be taken off from the frock, has removed the trouble of workman's installation bolt every time from. Once the bolt is not fixed on the panel, if the first through hole and the second through hole are not aligned, the bolt can be pressed down, and the bolt cannot be clamped. Secondly, if first through-hole and second through-hole have aimed at, also prevent that the bolt post from adsorbing on the second through-hole inner wall, let the second through-hole can't be worn out to the bolt post, lead to the nut to connect the difficulty.
