Description
Technical field
The invention belongs to technical field of hydraulic generators, particularly relate to a kind of Hydropower Unit generator lapping device of guide bearing up and down.
Background technology
At present, improving constantly of hydrogenerator single-machine capacity, the diameter dimension of upper and lower guide bearing is also increasing, as the SF96-42/10000 generating set, guide shoe is φ 2620mm under it, because the unit installation period is tight, often in manufactory, guide shoe is scraped ground, and the building site is mail in relevant rotating shaft usually in advance, and this just needs the lapping device of making and rotating shaft diameter same size, carries out the grinding scraping of guide shoe.
Cylindrical for lapping device requires roughness very high, must just can reach through honing processing after the Vehicle Processing.The tradition lapping device is made completely circular structure, as shown in Figure 6.There is following shortcoming in this project organization: (1) to big-and-middle-sized hydrogenerator, and along with the diameter dimension of the upper and lower guide bearing of increase of unit capacity is also increasing, its lapping device size, weight are also increasing, and the distortion of generation also increases.(2) because the lapping device profile is very big, operating personnel use very inconvenient, increase accident potential.(3) manufacturing cost height.
Summary of the invention
The present invention provides a kind of Hydropower Unit generator lapping device of guide bearing up and down for solving the technical problem that exists in the known technology.
The purpose of this invention is to provide a kind of Hydropower Unit generator with simple in structure, lightweight and portable in volume, saving cost, characteristics such as installation period is short, production efficiency is high, guide bearing Grinding Quality height lapping device of guide bearing up and down.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of Hydropower Unit generator is the lapping device of guide bearing up and down, and be characterized in: lapping device is fan-shaped, half chests formula structure, and one 40 ° to 60 ° circular arc steel plates are arranged, and there is the wedge shape chamfering at the arc plate two ends, and there is former circular arc steel plate inboard.
The present invention can also adopt following technical scheme:
Described Hydropower Unit generator is the lapping device of guide bearing up and down, and be characterized in: circular arc steel plate inboard is welded with two formers, and supporting steel pipe is arranged between the former.
Described Hydropower Unit generator is the lapping device of guide bearing up and down, and be characterized in: the circular arc steel plate is 20#, 35# or 45# steel plate, has carried out integrally annealed after inboard and two formers weld, and circular arc steel plate two ends have milled out the wedge shape chamfering.
Described Hydropower Unit generator is the lapping device of guide bearing up and down, and be characterized in: the roughness of circular arc steel plate outer surface reaches Ra0.4.
Advantage and good effect that the present invention has are:
The lapping device of guide bearing about the Hydropower Unit generator is owing to adopted brand-new technology scheme of the present invention, on sector structure, on the alternative completely circular structure of lower guide bearing watt lapping device, lower guide bearing watt lapping device structure, on more scientifically having satisfied, lower guide bearing watt is scraped the specification requirement that watt-hour carries out grinding technics, eliminated on the traditional handicraft, lower guide bearing watt lapping device volume heaviness, strengthen cost, yielding, shortcomings such as efficient is low, solved big, on the medium-sized Hydropower Unit generator, lower guide bearing watt grinding problem has shortened the installation period in power station effectively.
That the present invention has is simple in structure, lightweight and portable in volume, saving cost, installation period is short, production efficiency is high, guide bearing Grinding Quality advantages of higher.

The specific embodiment
For further understanding technology contents of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
A kind of Hydropower Unit generator is the lapping device of guide bearing up and down, for fan-shaped, half chests formula structure, one 50 ° of circular arc steel plates 1 is arranged, and circular arc steel plate 1 inboard is welded with two formers 2, and supporting steel pipe 3 is arranged between the former 2.There is the wedge shape chamfering at arc plate 1 two ends.Circular arc steel plate 1 is the 35# steel plate, has carried out integrally annealed after inboard and two formers 2 weld, and mills two ends wedge shape chamfering, Vehicle Processing and honing processing after the annealing.Circular arc steel plate 1 adopts the 35# steel plate, and its material is suitable for honing processing, reaches the roughness Ra0.4 requirement of circular arc external surface.
Present embodiment concrete structure and process:
The upper and lower guide bearing lapping device of Hydropower Unit generator is sector structure, and device adopts half chests formula structural design.One 40 ° to 60 ° circular arc steel plates are arranged, and the arc plate two ends are the wedge shape chamfering, and two formers of inboard welding increase steel pipe and support between the former.The circular arc steel plate adopts the 35# steel plate, and the 35# steel plate is easy to grinding, and its material is suitable for honing processing, reaches the roughness Ra0.4 requirement of circular arc external surface.Carry out integrally annealed after the welding of circular arc steel plate, mill two ends wedge shape chamfering, Vehicle Processing and honing processing after the annealing.
Half chests shape structural design vertical lathe carry out cylindrical add can utilize man-hour under former on lathe floral disc 4, carry out centering, be installed, former is inboard in the utilization measures with relative position measurement piece processing internal diameter gained size, obtains outside dimension accurately indirectly.Form honing wheel grinding motion track 5 during excircle of workpiece surface honing.Arc plate two end mills are processed into the wedge shape chamfering, have solved the lip-deep interrupted honing processing difficult problem of excircle of workpiece.
The upper and lower guide bearing lapping device of present embodiment Hydropower Unit has following characteristics:
