Abstract
The invention discloses a processing technology of a wind power generator hub, which relates to the technical field of designing on processing technologies of wind power generator hubs and is implemented according to the following steps of: (1) casting a hub blank and checking as required; (2) rough-turning and fine-turning an inner hole of the hub on a lathe and rough-turning blade hole end faces; (3) milling and boring an inner side face, an inner end face and a convex hole of the hub; (4) putting the hub on a workbench of a grinder so that the first blade hole end face is parallel to the workbench, fixing cushion blocks are arranged along the second blade hole end face and the third blade hole end face, adjusting the number of the cushion blocks and bolts on the cushion blocks so that the parallelism of the first blade hole end face meets the processing demand, and fine-grinding the first blade hole end face; (5) rotating the hub, adjusting the cushion blocks, and fine-grinding the second blade hole end face and the third blade hole end face; and (6) disassembling the wind power generator hub to finish the processing. The processing technology is characterized by the utilization of the cushion blocks to guarantee that the blade hole end faces of the hub and the workbench are on the same level.
Description
Technical field
The present invention relates to the processing technology design field of hub of wind power generator, is a kind of processing technology of hub of wind power generator concretely.
Background technology
Hub of wind power generator is the vitals that connects fan blade and main shaft, and these parts not only require the machining accuracy height, and volume is bigger, and are complex-shaped.Each faying face all has higher requirement to flatness, roughness, and angle is 120 ° of necessary strict guarantee between two adjacent faying faces, and each faying face stop portion requires fine finishining, and dimensional tolerance reaches 7 class precision standards.Usually adopt Large Machining Center to process the wheel hub of wind-driven generator in the existing technology, equipment has high input like this, the operating cost height, and also because the special shape of wheel hub causes relatively difficulty of clamping, then machining accuracy does not reach requirement.
Summary of the invention
In view of the defective that prior art exists, the purpose of this invention is to provide a kind of processing technology of utilizing common vertical machine processing to satisfy the hub of wind power generator of precision needs.
For achieving the above object, the present invention solves by the following technical programs: a kind of processing technology of hub of wind power generator, carry out according to the following steps: and (1) casting hub blank, and check and accept on request; (2) thick, finish turning wheelboss inner hole on lathe, rough turn vane hole end face; (3) to the hole of wheel hub medial surface, inner face, projection mill, boring processing; (4) wheel hub is placed on the workbench of grinding machine, make its vane hole end face one parallel with workbench, place fixedly cushion block along vane hole end face two and vane hole end face three, adjust the number of cushion block and the bolt on the cushion block, make the depth of parallelism of vane hole end face one reach the requirement of processing, carry out the correct grinding processing of vane hole end face one; (5) rotary hub is adjusted cushion block, and vane hole end face two and vane hole end face three are finish grinded processing; (6) unload the wheel hub of wind-force Electrical Discharge Machine, machine.
The invention is characterized in the level of utilizing cushion block to guarantee wheel hub vane hole end face and workbench, mill processing just can be carried out on ordinary machine tool.
The present invention has compared with prior art simplified processing technology, and process equipment is oversimplified, and reduced cost of investment, and the wheel hub precision of processing also satisfies instructions for use.
Description of drawings
Fig. 1 is a mill manufacturing procedure schematic diagram of the present invention.
The specific embodiment
Mark shown in Figure 1 is as follows: vane hole end face 1, vane hole end face 22, vane hole end face 33, cushion block 4, bolt 5.
A kind of processing technology of hub of wind power generator, carry out according to the following steps: (1) casting hub blank, and check and accept on request; (2) thick, finish turning wheelboss inner hole on lathe, rough turn vane hole end face; (3) to the hole of wheel hub medial surface, inner face, projection mill, boring processing; (4) wheel hub is placed on the workbench of grinding machine, make its vane hole end face 1 parallel with workbench, place fixedly cushion block 4 along vane hole end face 22 and vane hole end face 33, adjust the number of cushion block 4 and the bolt 5 on the cushion block 4, make the depth of parallelism of vane hole end face 1 reach the requirement of processing, carry out the correct grinding processing of vane hole end face 1; (5) rotary hub is adjusted cushion block, and vane hole end face 22 and vane hole end face 33 are finish grinded processing; (6) unload the wheel hub of wind-force Electrical Discharge Machine, machine.
The invention is characterized in the level of utilizing cushion block 4 to guarantee wheel hub vane hole end face as shown in Figure 1, mill processing just can be carried out on ordinary machine tool.
