Description
Technical field
It the utility model is related to a kind of parallelism error detection means.
Background technology
Line To Line parallelism error detection direction mainly has three kinds：First, a kind of direction is required；2nd, require orthogonal
Two kinds of directions；3rd, any direction is required；Measurement of the existing Line To Line parallelism error detection means to these three pointing needles pair
Method is relatively complicated, and efficiency is low.
Utility model content
The purpose of this utility model is that to solve the above problems and provides a kind of convenient and practical, good reliability, can
To improve the parallelism error detection means of measurement speed.
To achieve these goals, the utility model is achieved through the following technical solutions：A kind of parallelism error inspection
Device is surveyed, it includes detection platform, high crossbeam, low crossbeam, column, vee-block and dial gauge；The high crossbeam both sides pass through vertical
Post is fixed in detection platform；The high crossbeam both sides are fixed on column by spacer sleeve；The low crossbeam is consolidated by column
It is scheduled in detection platform；The low crossbeam both sides are fixed on column by spacer sleeve；Pressed from both sides respectively on the high crossbeam, low crossbeam
Fasten two groups of dial gauges；The high crossbeam is arranged right below the vee-block of two groups of positioning testees；The low below the crossbeam is set
There is the vee-block of one group of positioning testee；It is fixed on below the vee-block in detection platform.
Further, vee-block described in three groups forms equilateral triangle in detection platform.
Particularly, the high crossbeam, low crossbeam can be fixed on the optional position on column by spacer sleeve；The dial gauge
For dial gauge.
The utility model has the advantages that in summary：Parallelism error structure of the detecting device of the present utility model
Design, the Line To Line parallelism error of measurable any direction, convenient and practical, good reliability, measurement speed can be improved.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
The utility model is described in further detail for embodiment in below in conjunction with the accompanying drawings, but does not form to this reality
With new any restrictions.
Refer to shown in Fig. 1, the utility model provides a kind of technical scheme：A kind of parallelism error detection means, it is wrapped
Include detection platform 1, high crossbeam 2, low crossbeam 3, column 4, vee-block 5 and dial gauge 6；The high both sides of crossbeam 2 are fixed by column 4
In detection platform 1；The high both sides of crossbeam 2 are fixed on column 4 by spacer sleeve 7；Low crossbeam 3 is fixed on detection by column 4
On platform 1；The low both sides of crossbeam 3 are fixed on column 4 by spacer sleeve 7；It is fixedly clamped respectively on high crossbeam 2, low crossbeam 3 two groups
Dial gauge 6；High crossbeam 2 is arranged right below the vee-block 5 of two groups of positioning testees；The low lower section of crossbeam 3 is tested provided with one group of positioning
The vee-block 5 of object；The lower section of vee-block 5 is fixed in detection platform 1.
Three groups of vee-blocks 5 form equilateral triangle in detection platform 1.
High crossbeam 2, low crossbeam 3 can be fixed on the optional position on column 4 by spacer sleeve 7；Dial gauge 5 is dial gauge.
Measuring principle：During measurement, dial gauge 5 is first subjected to school zero, workpiece then is placed on into vee-block 5 will by spacer sleeve 7
High crossbeam 2 moves down, and is moved to directly over workpiece, reading m1, m2 of the dial gauge 6 of the high top of crossbeam 2 is read, then with known
Workpiece axial length l1 and the distance between two groups of dial gauges 6 l2, that is, utilize formulaDraw the first mistake
Difference；Then workpiece level is placed in detection platform 1, workpiece bottom is placed on the vee-block 5 of the high lower section of crossbeam 2, top
It is placed on the vee-block 5 of the low lower section of crossbeam 3, low crossbeam 3 is moved down by spacer sleeve 7, is moved to directly over workpiece, is read
Reading m1, m2 of the dial gauge 6 of the low top of crossbeam 3, then between the axial length l1 and two groups of dial gauges 6 of known workpiece
Distance l2, that is, utilize formulaDraw the second error amount；Then with the first error amount and the second error amount
Square parallelism error of the tolerance value as this workpiece.
Using illustrated embodiment as better embodiment of the present utility model, only it is used for convenient explanation the utility model, not
Make any formal limitation, any those of ordinary skill in the art to the utility model, if not departing from this
In the range of utility model carries technical characteristic, locally change or modify using made by the utility model disclosed technology content
Equivalent embodiment, and without departing from the technical characteristics of the utility model content, still fall within the utility model technical characteristic
In the range of.
