Abstract
The utility model provides a tool for detecting a coaxiality of a large span hole, comprising a tooling prolate axis and / or a tooling sleeve, wherein, the tooling prolate axis is coordinately used with the tooling sleeve; the tooling prolate axis is provided with a machining plane and a symmetric center line; after the tooling prolate axis or / and the tooling sleeve passes through a workpiece hole, the coaxiality of the workpiece hole and a height difference of a structural component can be detected through detecting the plane and the symmetric center line on the tooling prolate axis. The tooling axis of the utility model can be simply operated, and is safe and reliable. The tool solves a problem that the coaxiality of the large span hole can not be easily aligned, improves the work efficiency, reduces the intensity of labor, and reduces cost of materials and fee for installation as well.
Description
Technical field
The utility model belongs to the pick-up unit technical field, and particularly a kind of big span hole right alignment that is used for detects the instrument of using.
Background technology
The processing centering in big span hole is the technical barrier in the structural member manufacturing process all the time.Particularly in oil-well rig base production run, big span hole ubiquity.How to avoid or reduce the integral body processing in this type of hole effectively, enhance productivity, guarantee that product quality is the problem that the utmost point need solve.
Summary of the invention
The purpose of utility model is that design is a kind of novel big span hole right alignment detection frock axle.
Specifically, big span hole right alignment detects uses instrument, and it has a major axis (1), and major axis (1) radially-outer surface has processing plane.
Major axis (1) is a hollow-core construction; On the outer surface plane of major axis (1) groove is arranged; Major axis (1) two ends are pyramidal structure.
On major axis (1), be with frock cover (2), and be shaped on the plane that coincide with major axis (1) outside surface on frock cover (2) inside surface.Such structure is fit to measure when the major axis basic size of the basic size of workpiece hole and frock differs big.
The big span of the utility model hole right alignment detects and uses instrument, and structure and manufacturing process are simple, adopts hollow-core construction that frock weight is alleviated greatly; Adopt conical end capitiform formula, make frock axle easy accessibility, and safe and reliable; Change the frock cover and can satisfy the workpiece in different size hole, enlarged the scope of application of frock axle, economical and practical.Solved the problem of the right alignment that how to detect big span hole.
Description of drawings
Fig. 1 is that big span hole right alignment detects with instrument major axis structural representation.
Fig. 2 detects the frock nested structure synoptic diagram that is used with the instrument major axis for big span hole right alignment.
Fig. 3 is used synoptic diagram for big span hole right alignment detects with instrument major axis and frock cover.
Embodiment
Provided the utility model embodiment as accompanying drawing 1-3.A kind of novel big pitch-row centering detects fitting device, by the frock major axis or/and the frock cover form.It is characterized in that frock major axis (1) uses separately or is used with frock cover (2).A kind of situation is directly to penetrate frock major axis (1) in the workpiece hole; Another kind of situation is earlier frock cover (2) to be penetrated in the workpiece hole, then frock major axis (1) is penetrated in the frock cover (2) again.
Frock major axis outside dimension is than workpiece ear seat hole dimension little (having tolerance control); Frock cover outside dimension than workpiece hole size little (tolerance control is arranged), internal diameter size than frock major axis outside dimension big (having tolerance to control).
The utility model uses in two kinds of situation:
(tolerance difference when workpiece hole basic size is identical with frock axle basic size, the size of frock major axis is littler than the size of workpiece hole), directly the frock major axis is penetrated in the workpiece hole, rotate the frock major axis, make the plane on the frock major axis outside surface be positioned at horizontal level, detect with frame level.The difference in height of surveying plane on the frock major axis of workpiece hole both sides with transit get final product the difference in height in this segment distance of portalling.Wear chalk line, make the chalk line two ends be positioned at the frock major axis outside and go up on the frock major axis center line of plane mark, the deviation of center line and chalk line can draw the deviation in hole on the workpiece on the plane by detecting on the frock major axis inboard.Comprehensive so above measurement result can draw the coaxiality error in hole on the workpiece.
When the basic size of workpiece hole and frock axle basic size differ big.Earlier the frock cover is penetrated workpiece hole (frock cover outside dimension have the requirement of cooperation, internal diameter size also to have cooperate requirement) with frock axle outside dimension with the workpiece hole size.All the other detection methods are identical with situation noted earlier.Change the frock cover to satisfy the workpiece in different size hole.
Claims (5)
1, instrument is used in big span hole right alignment detection, it is characterized in that having a major axis (1), and major axis (1) radially-outer surface has processing plane.
2, instrument is used in 1 described big span hole right alignment detection according to claims, and it is characterized in that: major axis (1) is hollow-core construction.
3, use instrument according to claims 1 or 2 described big span hole right alignmenies detections, it is characterized in that: on the outer surface plane of major axis (1) groove is arranged.
4, instrument is used in 3 described big span hole right alignmenies detections according to claims, and it is characterized in that: major axis (1) two ends are pyramidal structure.
5, use instrument according to claims 3 or 4 described big span hole right alignmenies detections, it is characterized in that: be with frock cover (2) on the major axis (1), and be shaped on the plane that coincide with major axis (1) outside surface on frock cover (2) inside surface.
