A kind of machine tool guideway measurement apparatus
Technical field
The application relates to machine tool guideway and installs and measure, and is particularly well-suited to rail plate or linear guides
Installation and measurement.
Background technology
In Installing machine tool is debugged, reliability and accuracy that machine tool guideway is installed and measured are to protect
The card of paramount importance basis of Installing machine tool precision, machine tool guideway is modal rail plate and line
Two kinds of guide rail of property, when the installation and debugging of lathe, generally will be led lathe by measurement apparatus
Linearity and the depth of parallelism of rail measure.Existing measurement apparatus is generally according to the lathe used
Distance between guide rail form and guide rail selects different fixed Overbridge devices, its structure shape
Formula cannot adjust has uniqueness, therefore when manufacture is connected support with guide rail to its machining accuracy
Requiring higher, processing technique is complicated, simultaneously structural adjustment in machine tool guideway installation and debugging are measured
Complexity, measures stability and poor reliability, guide rail linearity and the mistake of the depth of parallelism during Installing machine tool
Difference is bigger so that fixed Overbridge device can not go out the geometric accuracy of guide rails assembling by actual response.
Summary of the invention
In order to improve guide rails assembling debugging measure during, fixed Overbridge device versatility and
Interchangeability is poor, measures stability and the defect of poor reliability, and the present invention provides a kind of machine tool guideway to survey
Amount device.
The measurement apparatus of a kind of machine tool guideway, measurement apparatus is by guide supporting, Vierendeel girder, adjustment
Support, dial framework supports composition, it is characterised in that described Vierendeel girder is by an entablature, with
Two sills that entablature is parallel, and connect the connecting rod composition one equilateral three of lower and upper cross-member
The truss structure of angle body, entablature and two sills are three seamed edges of equilateral triangle body respectively,
Described guide supporting is a connector, and its lower surface is connected with tested guide rail, guide supporting
Upper surface by two contour connectors respectively one end with two sills fix, described
Adjustment support by adjusting frame, roller and connecting shaft form, this adjustment frame Height Adjustable,
Adjust frame by two contour connectors respectively the other end with two sills fix, adjustment
The roller supported can roll on opposite side guide rail, and dial framework support is the knot of a fixation measuring table
Structure, it is fixed on the side sill of grid beam frame by dismountable connector, additionally upper
The top of crossbeam is provided with one and places plate.
Described guide supporting is a flat board attachment structure, when tested guide rail is linear guides,
Guide supporting is then directly connected with linear guides slide block by connecting hole;Support be provided with linearly
The connecting hole that guide rail slide block is fixing.When tested guide rail is rail plate, under guide supporting
Surface can connect the guide roller being connected with sliding guide rolling.
During use, respectively guide supporting, adjustment support, dial framework are supported and fixed on Vierendeel girder,
Its position can be adjusted according to the span of machine tool guideway, putting of Vierendeel girder entablature top
Put placement frame level on plate, by observing the regulation adjustment of frame level vial side-play amount
The position of support, it is ensured that guide supporting and adjustment are supported in same level, and measurement table is fixed on
Measurement table is touched on tested guide rail face on supporting by dial framework.Enter along the machine tool guideway direction of motion
Line displacement, observes the reading measuring table, adjusts machine tool guideway precision, meets the peace of machine tool guideway
Reload request.
It is an advantage of the current invention that: 1) simple and reasonable, there is versatility and interchangeability, have
The defect that when avoiding machine tool guideway installation, the geometric accuracy certainty of measurement of guide rail is the highest of effect.2)
The fixed position that guide supporting and adjustment are supported on grid beam frame is adjustable, can measure different in width
Guide rail.3) bearing height that adjustment supports can be adjusted and connect, and reduces the processing essence of measurement structure
Degree.4) guide supporting is one and is interchangeably connectable part, by changing connecting hole or directive wheel
It is adapted to different guide rail structures, linear guides can be measured, also can measure rail plate.
Below in conjunction with embodiment accompanying drawing, this application is described in further detail.

Detailed description of the invention
See accompanying drawing, the machine tool guideway measurement apparatus of the application, by guide supporting 1, Vierendeel girder 2,
Adjust support 3, dial framework supports 5 compositions, and described Vierendeel girder 2 is by an entablature 6, with
Two sills 7 that entablature is parallel, and the connecting rod 8 connecting lower and upper cross-member forms one etc.
The truss structure of limit triangle body, entablature and two sills are three of equilateral triangle body respectively
Seamed edge, the lower surface of described guide supporting 1 is connected with tested guide rail, the upper table of guide supporting
Face by two contour connectors 9 respectively one end with two sills fix, described tune
Whole support 3 is formed by adjusting frame 10, roller 11 and connecting shaft 12, the height of this adjustment frame 10
Degree scalable, adjust frame 10 by two contour connectors 9 another with two sills respectively
One end is fixed, and the roller 11 adjusting support 3 can roll on opposite side guide rail, and dial framework supports 5
Being the structure of a fixation measuring table, it is fixed on the one of grid beam frame by dismountable connector
On the sill of side, additionally the top at entablature 6 is provided with a level indicator and places plate 13.
Guide rail device of machine tool is when measuring linear guides 4, and guide supporting 1 is then straight by connecting hole
Connect and be connected with linear guides slide block 14;When tested guide rail is rail plate 17, prop up at guide rail
The lower surface of support 1 can connect slide-and-guide wheel 16 and be connected with rail plate 17 rolling.
The use state embodiment provided is to install and as a example by measurement, such as Fig. 1 institute by linear guides
Show, the linear guides of the machine tool guideway measurement apparatus of the application is supported 1 linear with lathe one
The linear guides slide block 14 of guide rail couples, and adjusting the roller 11 supported can be on opposite side guide rail
Rolling, level indicator is placed on the placement plate 13 of Vierendeel girder entablature, is used for measuring adjustment and supports
With the depth of parallelism of guide supporting, the adjustment frame 10 supported by adjustment during deviation and roller
The relative position of 11, adjusts support rear connecting shaft 12 parallel with guide supporting and fixes, survey
The measurement table of amount guide rail is fixed on dial framework and supports on 5, and the indicator of measurement table touches tested guide rail
On, mobile machine tool rail survey unit, tested machine tool guideway can be indicated by measurement table
Linearity and the depth of parallelism.
