Description
Technical field
The present invention relates to field of precision measurement, more particularly to a kind of circular path contourgraph and measuring method.
Background technology
Present common contourgraph, the measurement of profile on straight path can only be realized, but be processed in present part
In run into and need to measure height and R angles etc. on circular path, when using measurement for linear trajectory, as a result certainly will inaccuracy, if
If three-dimensional coordinates measurement, some planes are small or shape is not very regular data and can not accurately be gathered, so needing
Invent a kind of contourgraph that can measure circular path profile.
The content of the invention
The invention provides a kind of circular path contourgraph, it can measure the profile on part circular path.
The invention provides a kind of measuring method, and it can measure the profile on part circular path.
In order to realize the purpose, contourgraph of the present invention provides a kind of circular path contourgraph, and the contourgraph includes：Gauge head
System, transverse arm, column, counterweight, rotary work turntable, turntable cross track, the rotary table rotatable movement, turntable is very
As guide rail can make rotary table transverse movement, transverse arm is located in the mounting hole on column, and one end of transverse arm is provided with gauge head system,
The other end of transverse arm is provided with counterweight, and column is fixed on contourgraph pedestal.
The invention provides a kind of measuring method, this method includes surveying rotary work state offset into the half of locus circle
Footpath, rotary table rotates during measurement, radian and elevation information in the rotation of gauge head system acquisition, by computing, draws circular arc
The profile diagram in face.
The invention has the advantages that：The present invention realizes the profile measurement on circular path.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
The top view of Fig. 2 present invention.
Fig. 3 is the schematic diagram of present invention measurement workpiece circular path profile.
Embodiment
The invention provides a kind of circular path contourgraph, and it is by rotary table 1, turntable cross slide way 2, gauge head system
3, transverse arm 4, column 5, counterweight 6, workpiece 7 forms.
The rotary table 1 is circular table, can be with rotary motion, and turntable cross slide way 2 is under rotary table 1
Side, it is possible to achieve the transverse movement of rotary table 1, rotary table 1 and turntable cross slide way 2 form a workbench pair,
When workpiece 7 is placed on workbench, by the rotation and transverse movement of the secondary achievable workpiece 7 of the workbench, gauge head system 3, match somebody with somebody
6 both ends for being respectively placed in transverse arm 4 are weighed, transverse arm 4 is placed on column 5, and column 5 is fixed in the contourgraph agent structure, 4 liang of transverse arm
End can be swung up and down, so that the probe of gauge head system 3 is used to ensure gauge head system with the surface joint of workpiece 7, counterweight 6 all the time
3 and transverse arm 4 keep balance.
The present invention simultaneously additionally provide a kind of measuring method, as shown in Fig. 2 using it is of the invention when first by measured workpiece 7
Circular arc and workbench 1 cylindrical correction is measured, ensures that the center of the cylindrical and tested Circular test of workbench 1 is concentric, then passes through
Table offsets are tested the radius R of locus circle by cross slide way 2, and now workbench 1 rotates, the feed back height data h of gauge head system 3
Onto host computer, workbench 1 will rotate radian measure alpha and radius of deflection R uploads to host computer, and this just obtains the wink on measured workpiece surface
When position coordinate, X-coordinate h, Y-coordinate is α R.Connected a little during rotary table is rotated, just obtain corresponding rail
Mark（As shown in Figure 3）, the track on workpiece centre radius R circle circular cross-sections is just recorded in the track.
Claims (3)
1. a kind of circular path contourgraph, it is by rotary table 1, turntable cross slide way 2, gauge head system 3, transverse arm 4, column 5,
Counterweight 6, workpiece 7 form.
