Description
Technical field
The utility model relates to mechanical engineering technical fields, and in particular to a kind of high positioning device such as rotary main shaft.
Background technique
With the development of the sophisticated technologies such as space flight, laser, nuclear energy, the requirement to precision is higher and higher, in revolving body
The positioning of heart line is particularly critical, and the positioning of revolving body centre-height directly affects the positioning of its two end device, if revolving body
Centre-height cannot determine well, with the change of the rotor-support-foundation system diameter of axle, the centre-height of entire Rotor-Bearing System also with
Change, bring workload is huge, so a kind of positioning of centre-height positioning for capableing of shaft is needed to clamp dress
It sets.
Domestic some shafting clamping and positioning devices, such as V-block, these devices play clamping using V-groove shaft
Effect, pressing plate and the V-block of vertical direction are threaded, and are haved the function that shaft clamps and are positioned, but it is difficult to ensure that
Axial center's height does not change.With the change of the diameter of axle, centre-height also changes therewith, it is ensured that its centre-height is solid
It is fixed, to its positioning operation complexity, heavy workload.It is only capable of shaft for common clamping device at present and is only capable of playing to be fixedly clamped
Effect, it cannot be guaranteed that the axis mounting height of the different diameters of axle is fixed, measurement, the processing of shaft bring very big inconvenience.
Utility model content
In view of this, requiring to guarantee that its centre-height is constant when axis clamping of the utility model in order to solve the different diameters of axle
Problem provides a kind of high positioning devices such as rotary main shaft.
In order to solve the problems existing in the prior art, the technical solution of the utility model is: a kind of contour positioning of rotary main shaft
Device, it is characterised in that: including pedestal and revolving body hold assembly, the upper surface indent of the pedestal be provided with two it is equal
Capable T-shape slot guide rail is respectively arranged with 2 slidable cushion blocks in two T-shape slot guide rails；
The structure of the revolving body hold assembly includes that two long sides are affixed symmetrically arranged " h " type, and " h " type is affixed two
It is provided on a face symmetrical " rhomboid cavity of V " type groove composition, in the upper and lower part of " h " type of two symmetrical settings
Between connected by horizontal long bolt, two step surfaces of revolving body hold assembly are respectively set there are two vertical long bolt, two
Vertical long bolt is connect with cushion block respectively, and the horizontal long bolt and vertical long bolt pass through with revolving body hold assembly respectively
Stop nut is fixed.
There are two the horizontal long bolt settings.
The vertical long bolt is threadedly coupled with cushion block.
Compared with prior art, as follows the advantages of the utility model:
1, the utility model can clamp the revolving bodies of the different diameters of axle in the device, guarantee that its centre-height is constant, be axis
It is convenient that the fixation and installation of system provide, and reduces bring machine error due to multiple clamping shafting；
2, the utility model is oriented to by vertical long bolt, and revolving body hold assembly part is slided in T-slot guide rail,
The relative position for adjusting two revolving body hold assembly parts, the revolving bodies of the different diameters of axle can be clamped by meeting the device.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
It is described the present embodiment provides a kind of high positioning device such as rotary main shaft, including pedestal 7 and revolving body hold assembly 2
The upper surface indent of pedestal 7 be provided with two parallel T-shape slot guide rails 1, be respectively set in two T-shape slot guide rails 1
There are 2 slidable cushion blocks 6；
The structure of above-mentioned revolving body hold assembly 2 includes that two long sides are affixed symmetrically arranged " h " type, and " h " type is affixed two
It is provided on a face symmetrical " rhomboid cavity of V " type groove composition, in the upper and lower part of " h " type of two symmetrical settings
Between connected by horizontal long bolt 3, two step surfaces of revolving body hold assembly 2 are respectively set there are two vertical long bolt 4, two
A vertical long bolt 4 is threadedly coupled with cushion block 6 respectively, and the horizontal long bolt 3 and vertical long bolt 4 are pressed from both sides with revolving body respectively
It is fixed by stop nut 5 to hold component 2.
The utility model cushion block 6 slides in T-slot, drives vertical long bolt 4 and revolving body hold assembly 2 in T-slot
It inside radially slides, when pairs of revolving body hold assembly 2 slides into certain position, calibration shafting position, in the horizontal direction, by wearing
3 both ends of horizontal long bolt for crossing revolving body hold assembly 2, tighten limit by stop nut 5, in vertical direction by passing through T
The long bolt 4 vertical with revolving body hold assembly 2 of type groove guide rail 1, tightens limit with stop nut 5.
The above, the only preferred embodiment of the utility model, are not intended to limit the protection of the utility model
Range.
