Abstract
A wide-distance superlong multi-guide rail structured tooling comprises two outer guide rails, a basic guide rail, an inner guide rail and a tooling, wherein the outer guide rails are mounted on a foundation platform in parallel, and the basic guide rail and the inner guide rail are arranged between the outer guide rails. The outer guide rails and the inner guide rail are fixedly mounted on the foundation platform by barrels and connecting bolts nested in the foundation platform. A slider matched with one end of the tooling is mounted on each guide rail, and two ends of the tooling are combined with the sliders of the adjacent guide rails in an adjustable-span connecting manner. Since the two ends of the tooling are combined with the sliders of the adjacent guide rails in an adjustable-span connecting manner, the tooling can mount two different spans of guide rails, and cost is saved. By means of the basic guide rail and the inner guide rail which are used as base for mounting the outer guide rails, the integral accuracy of the four guide rails can be well ensured due to high accuracy of the basic guide rail. In addition, the wide-distance superlong multi-guide rail structured tooling is simple and quick to mount.
Description
Technical field
The present invention relates to a kind of a plurality of overlength of width having in the plant equipment of width overlength closed slide that is applied to is led
Rail structure and frock, particularly relate to one kind be applied to large-scale（As Three Gorges）Ship lift drives the crucial driving section of elevating mechanism
Part（Gear, tooth bar）The width overlength closed slide installation method needed for combination property checking test platform and frock.
Background technology
Three-Gorges Ship-lift drives needed for the crucial drive disk assembly gear of elevating mechanism, the combination property checking test platform of tooth bar
Super-long guiding rail be always about ten meters, be made up of the splicing of many guide rails, wherein one length close to six meters, have four parallel super
Long guideway, span is about two meters, about 20 tons of every guide rail load-bearing, and in process of the test, mobile platform needs to move in circles on guide rail
Run, the linear precision of therefore every guide rail, the parallel accuracy between four guide rails, plane precision of guide rail upper surface etc. requires
All very high, its error can directly influence data acquisition results during test, and when precision is low, frictional force is correspondingly improved, fortune
Row resistance increases, and affects service life.The degreeof tortuosity of super-long guiding rail larger it is necessary to improve installation accuracy, error during installation
Less, the precision of linear motion and durability degree can be higher, thus being smoothed out of guarantee test.
Content of the invention
The purpose of the present invention is precisely in order to solving the above problems and providing a kind of machine being applicable to overlength closed slide
Width on tool equipment a plurality of super-long guiding rail structure and frock.
The purpose of the present invention is realized by following technical proposals：
The width a plurality of super-long guiding rail structure of the present invention and frock include being arranged on basic platform in the way of be arrangeding in parallel
On two follower rails, the basic rack being located between two follower rails, inboard track, and frock；Described two outer
Side rails and inboard track are fixedly mounted on basic platform by the swivel nut and connecting bolt being inlaid on basic platform respectively
On；Described basic rack includes swivel nut by being inlaid on basic platform and connecting bolt to install by way of longitudinally disposed
The overlength basic rack of plane on basic platform, is set in parallel in overlength basic rack side and by alignment pin, bolt peace
Be contained in the positioning datum plate of plane on basic platform, overlength basic rack opposite side, be vertically arranged with several and pass through
Bearing pin is arranged on the eccentric disc on basic platform, is provided with slide block, is used on overlength basic rack in the way of being slidably matched
Pretension slide block is simultaneously installed the mounting blocks of measuring instrument and is fixed on slide block；The relatively thin side of positioning datum plate is used for positioning overlength base
One side of quasi- guide rail, eccentric disc is used for positioning another side of overlength basic rack；Each guide rail be separately installed with
The slide block matching in described frock one end, the connected mode and adjacent two of scalable span is passed through at the two ends of described frock respectively
Slide block on root guide rail combines.
Heretofore described positioning datum plate is made up of the plank section that some front and back ends connect successively；Described overlength benchmark
Guide rail is made up of the guide rail section that some front and back ends connect successively；And the total length of described positioning datum plate leads more than overlength benchmark
The total length of rail, and arrange in the way of outside positioning datum plate two ends extend respectively to overlength basic rack two ends, described outer
Side rails, inboard track are equally all made up of the guide rail section that some front and back ends connect successively.
The concrete installation method of the present invention is as follows：
First basic rack is installed on basic platform, so that various precision is maintained in requirement, then remove mounting blocks,
Slide block is preserved for ensuing installation.Then inboard track is installed, every track loads two slide blocks, with tool part by four
Individual slide block couples together, and simultaneously by four slide block pretensions, promotes frock that slide block is moved on guide rail, first that inboard track is solid
Determine tools for bolts ' pretension, then according to the method tightened to two from centre, tighten bolt when measurement ensures precision, in the process
Slide block is required to move smooth, no unsmooth phenomenon, due to basic rack high precision, the therefore installation accuracy of inboard track also can compare
High.After inboard track is installed, benchmark that inboard track and basic rack are installed as follower rail, with slide block and frock by with
On method install two follower rails.Notice during installation mutually staggering in the guide rail section joint of four guide rails.Article two, guide rail
Span is relatively wide, close to two meters it is therefore necessary to ensure the rigidity of tool part, it is to avoid the deformation of tool part causes guide rail mounting precision
Decline, frock is using not only can guarantee that rigidity, weight but also lighter foundry goods.Whole installation process simple and fast, and can be well
Ensure the overall precision of a plurality of guide rail.
Beneficial effects of the present invention are as follows：
Beneficial effects of the present invention are as follows：
1st, structure is simple, easy to operate, and positioning precision is high, is that the accuracy of test data provides reliable guarantee.
2nd, do not destroy the surface of basic platform, do not increase the adnexaes such as firm banking, decrease cumulative error, save simultaneously
Cost.
3rd, guide rail is fixed on basic platform by swivel nut, improves condition of contact, improves the life-span and is easy to keep in repair.
4 further, since the two ends of described frock are respectively by connected mode and adjacent two guide rails of scalable span
On slide block combine, this also just solves the demand being suitable for installing two kinds of different span guide rails using a tool part
Problem, saves cost.
