Description

Jig for machining wind power hub

Technical Field

The utility model relates to a tool is used in processing of wind-powered electricity generation wheel hub.

Background

The wind power generation is very environment-friendly, and the wind energy is huge, so that the wind power generation is increasingly paid attention by various countries in the world; human beings develop and utilize wind energy very rarely, and only one aerogenerator in the world is three leaves one post now, and its installation use is in-process, and the wind regime requirement to the environment is high, and this type of aerogenerator is to the size restriction many simultaneously, and the investment is huge, also leads to the cost of wind power generation to remain high. The development trend of wind driven generators is that the power is larger and larger, and the specification and the size are correspondingly larger and larger, the machining of high-power wind power, such as the machining of a wind power base and a wind power hub, needs corresponding tool fixtures, and the machining of a large-size wind power base does not have corresponding tool fixtures to ensure the stability and the precision of the machining. In addition, in the process of correcting and adjusting the clamp before machining, the process of correcting and adjusting is long, the labor hour is consumed, and the production efficiency is influenced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect that exists among the prior art, provide tool for the processing of wind-powered electricity generation wheel hub, press from both sides tightly firm and good adjustment, rectify the adjustment process easy, save man-hour, improved work efficiency.

In order to achieve the purpose, the technical scheme of the utility model is to design a jig for processing a wind power wheel hub, which comprises a first-order processing jig and a second-order processing jig, wherein the first-order processing jig and the second-order processing jig are both provided with jig bases, a support is arranged on the jig bases, a pressing plate is arranged in a matching way with the support, one end of the pressing plate is fixedly provided with a sliding column, the pressing plate is arranged on the support or the base in a sliding way through the sliding column, a round hole matched with the sliding column is arranged on the support or the base, a threaded hole is arranged on the pressing plate, a screw rod is arranged in a matching way with the threaded hole, a threaded hole matched with the screw rod is arranged; a fixed block made of ferromagnetic materials is fixedly arranged at one end of the pressure plate far away from the sliding column; the first-order processing jig and the second-order processing jig further comprise electromagnets which are arranged in a matched mode. The screw-out quantity of the screws on all the supports is about 10-30 mm (considering that the screw-out quantity can be adjusted to be larger until the screws are separated from the supports, namely the screws and the supports are not connected in a state, so that the screws can be ensured to have enough regulating quantity. And meanwhile, a locking nut is required to be used, and when the length of the screw is fixed after the screw is adjusted, the screw is fixed by the locking nut. In addition, the number of the locking pressing plates of the tool is not less than 12, and the outer circle is uniformly distributed at least more than 8. The torque of each locking point is more than or equal to 260 KN.

The further technical scheme is that a jig base of the first-order processing jig is annular, six adjustable supports are annularly arranged on the annular jig base, five side tops are annularly arranged on the annular jig base, and a ring formed by the side tops is positioned outside a ring formed by the adjustable supports; at least twelve threaded holes are formed in the base, each threaded hole is adaptive to one screw rod, each screw rod is correspondingly provided with a pressing plate matched with the screw rod, and the adjustable support or the movable support is arranged below the pressing plate. Because the tight face of add during one-step processing is wind-powered electricity generation wheel hub's side, consequently lay on anchor clamps after slightly inclining, consequently set up five side tops can, simple structure can realize the effect of fine anchor clamps work piece.

The second-order processing jig is characterized in that six equal-height supports are annularly arranged on a jig base of the second-order processing jig, two equal-height supports with pin holes formed in the end faces are arranged outside the six equal-height supports, and positioning pin columns are arranged in a matched mode with the pin holes; six pressing plates are further arranged on the base in an annular mode, and a ring formed by the six pressing plates is located inside a ring formed by six equal-height supports.

The further technical scheme is that the pressing plate is rectangular plate-shaped, a sliding column is fixedly arranged below the edge of one short edge of the pressing plate, and a fixing block made of ferromagnetic material is fixedly arranged on the side face of the edge of the other short edge of the pressing plate. Like this hoist and mount work piece and lay to the frock before, through arranging the electro-magnet in the frock middle part, can realize rotating all clamp plates to its fixed block towards the frock middle part after the circular telegram, it is more convenient when laying the work piece like this, the clamp plate influence can not appear and lay still need the condition that manual adjustment rotated the clamp plate.

The utility model has the advantages and the beneficial effects that: the clamping is stable and well adjusted, and the adjustment process is easy to correct and adjust, the working time is saved and the working efficiency is improved through the matching of a plurality of different structures; because the tight face of add during one-step processing is wind-powered electricity generation wheel hub's side, consequently lay on anchor clamps after slightly inclining, consequently set up five side tops can, simple structure can realize the effect of fine anchor clamps work piece. Before the hoist and mount work piece is laid to the frock, through arranging the electro-magnet in the frock middle part, can realize rotating all clamp plates to its fixed block towards the frock middle part after the circular telegram, it is more convenient when laying the work piece like this, the clamp plate influence can not appear and lay the condition that still needs manual adjustment to rotate the clamp plate.
