Sensor is scanned the oblate cylindricality end plate end face in assisted calibration part, and obtains machine tool chief axis axis according to scan data
The position equation of line.
Referring to Fig. 3.Fig. 3 is carried out under control of the controller according to the laser sensor 3 shown in an illustrative embodiments
One-dimensional scanning process schematic.Below in conjunction with Fig. 3 and Hexapod coordinate systems the present invention will be described in detail machine tool chief axis axis
Line position acquisition methods.
Before determining machine tool chief axis axis line position, workpiece to be processed can be passed through work piece holder 20 such as vacuum cup
It is installed to 10 end of machine tool chief axis, assisted calibration part 4 is installed on work piece holder 20, without 20 situation of work piece holder
Under, assisted calibration part 4 is mounted directly to 10 end of machine tool chief axis.
Traditional method of adjustment, adjustment can be used to ensure the concentricity of assisted calibration part 4 and machine tool chief axis 10, such as adjusted
Adjusting method can be such：Machine tool chief axis 10 is rotated, the radial run-out value on 4 cylindrical surface of assisted calibration part is measured, is beating
By tapping the means such as assisted calibration part 4 when peak value occurs in value, (location of workpiece is synchronized for the position of fine tuning assisted calibration part 4
Adjustment), manually adjusting can control the radial run-out value of assisted calibration part 4 within 2~3 microns.
Certainly, the method for adjustment for making assisted calibration part 4 coaxial with machine tool chief axis 10 is not limited to above-mentioned specific descriptions,
The semi-automatic adjustment concentricity method of his method of adjustment such as adjust automatically concentricity method and supplementary instrument can be adapted for
The present invention.
Under Hexapod coordinate systems, the position coordinates of the laser beam emitting point of laser sensor are (XL,YL,ZL), laser
The direction of the launch of beam is identical as the normal direction of upper mounting plate 11 of Hexapod mobile platforms 1, if 11 method of upper mounting plate of Hexapod
Line direction vector is (UH,VH,WH), then the direction of the launch of laser beam is also (UH,VH,WH)。
After the concentricity adjustment of assisted calibration part 4 and machine tool chief axis 10 is completed, controller controls laser sensor 3 and carries out
2 dimension scannings.For example, controller controls the upper mounting plate 11 of Hexapod mobile platforms 1 along the rotation of U axis and/or V axis
Cheng Zhong, laser sensor 3 is scanned the end face 411 of oblate cylindricality end plate 41, and scan data is sent to controller；When
When peak value occurs in scanning process in the signal of laser signal receivers, the direction where moment W axis is exactly machine tool chief axis 10
Central axes direction.Therefore, by the method for 2 dimension scannings, the direction vector of the central axes of machine tool chief axis 10 can be accurately obtained
(UH,VH,WH)。
The laser signal transmitter of laser sensor can emit laser signal along the z-axis direction of Hexapod mobile platforms 1,
The laser signal returns to laser signal receivers after the end face of assisted calibration part 4 411 is reflected.Controller is by calculating laser letter
The time difference for number sending out and receiving, just can accurately plan to calculate between the end face 411 and laser sensor of assisted calibration part 4 away from
From further calculating out between the central point of the upper mounting plate 11 of Hexapod mobile platforms and the end face 411 of assisted calibration part 4
Distance, distance d meet equation：
D=d1+ZL
Wherein d1It is the distance between end face 411 and the laser sensor 3 of assisted calibration part 4, is measured by laser sensor 3
It obtains, ZLIt is the height of laser sensor 3
After obtaining the direction vector of central axes of machine tool chief axis 10, Hexapod movements are adjusted under control of the controller
11 position of upper mounting plate of platform 1 makes the normal direction of upper mounting plate 11 be overlapped with 10 central axes direction of machine tool chief axis.Next, control
Device control laser sensor 3 processed carries out one-dimensional scanning.For example, as shown in figure 3, working as the upper mounting plate of Hexapod mobile platforms 1
During 11 move in the X-axis direction, laser sensor 3 is scanned the end face 411 of oblate cylindricality end plate 41, and will scan number
According to being sent to controller, when 3 first time of laser sensor detecting step signal, the end face of oblate cylindricality end plate 41 at this time
The coordinate of 411 central points is (X1,Y1,Z1), when controller detects step signal for the second time, oblate cylindricality end plate 41 at this time
411 central point of end face coordinate be (X2,Y1,Z1).Laser sensor 3 when controller for the first time detect step signal when, this
When oblate cylindricality end plate 41 the coordinate of 411 central point of end face be (X3,Y3,Z1), detect rank second when laser sensor 3
When jump signal, the coordinate of 411 central point of end face of oblate cylindricality end plate 41 is (X at this time3,Y4,Z1)].Therefore, it is sat in Hexapod
Under mark system, the position of the end face 411 of the oblate cylindricality end plate 41 of assisted calibration part 4 isMost
Eventually, obtain 10 central axes of machine tool chief axis is in the linear equation (x, y, z) of Hexapod coordinate systems：
Determining 10 central axes of machine tool chief axis after the linear equation of Hexapod coordinate systems, you can control is straight according to this
Line equation carries out subsequent processing.When lathe is processed, by control Hexapod mobile platforms 1 upper mounting plate 11 it is flat
Shifting and rotary motion, cut workpiece surface to control cutter 30.Under Hexapod coordinate systems, 30 cutting point of cutter
Position coordinates can be by 11 center position coordinates of upper mounting plate of Hexapod mobile platforms 1, the geometric parameter of cutter and to be processed
Workpiece surface shape is calculated, then the position coordinates of Tool in Cutting point are represented by (XT,YT,ZT), tool orientation with
11 normal direction of upper mounting plate of Hexapod mobile platforms 1 is identical, is (UH,VH,WH)。
