Description
Technical field:
The present invention is relevant with the high precision angle measurement unit, and is relevant with the wide-angle measurement mechanism of laser angle interferometer and multiteeth indexing table combination especially.
Background technology:
Utilize the combination of high precision multiteeth indexing table and laser angle interferometer, can carry out high-acruracy survey the bearing accuracy of NC rotary table.At present, external such advanced main flow laser surveying instrument, because the lifting of the multiteeth indexing table table top of laser target mirror is installed, it is serious to cause laser intensity to lose, and produces to measure fault unstable even that interruption is measured.The present invention promptly invents out the multiteeth indexing table measurement mechanism of not lifting of table top at this problem, preferably resolve accuracy and integrity problem that laser angle interferometer is measured the NC rotary table bearing accuracy.
Multiteeth indexing table is to utilize the upper and lower a pair of number of teeth contrate gear identical with modulus to realize the calibration function with the different engagement of position, angle, location, is widely used in fields such as Precision Machining and precision measurement.
Fig. 1 is the existing multiteeth indexing table structural representation that is used for laser measurement NC rotary table bearing accuracy, and last fluted disc 2 is stable positioning states with lower tooth disk 1 engagement.The use of multiteeth indexing table is divided into three steps: 1. motor 13 drive transmission devices 14 rise fluted disc 2, break away from engagement; 2. lower tooth disk 1 drives the angle that inserts to requirement by NC rotary table, and the transposition while, motor 3 drive transmission devices 4 make fluted disc 2 turn round the angle of requirement synchronously to the reverse direction of lower tooth disk 1 rotation; 3. motor 13 drive transmission devices 14 fall fluted disc 2, with lower tooth disk 1 stable engagement once more.
Laser angle interferometer and multiteeth indexing table shown in Figure 1 are used in combination, and can constitute a cover wide-angle measuring system, as shown in Figure 2.Target mirror 23 is installed on the table top of fluted disc 2, and the laser beam that laser head 35 sends is by angle interference mirror 34 directive Ba Mirror 23.During measurement, last fluted disc 2 at first rises, measured body 26 (together with lower tooth disk 1) is desired the angle measurement degree with respect to last fluted disc 2 (together with Ba Mirror 23) rotation one, rotation simultaneously, last fluted disc 2 (together with target mirror 23) turns round synchronously to lower tooth disk 1 rotating reverse direction desires the angle measurement degree, left alone without help steady after, last fluted disc 2 (together with target mirror 23) falls, with lower tooth disk 1 stable engagement, laser angle interferometer shows measured body 26 rotating angular error values.Last fluted disc 2 rises again, and measured body 26 rotates one again and desires the angle measurement degree, and work above repeating can record measured body 26 next rotating angular error; So repeat, can record the angle of revolution error of NC rotary table complete cycle.Measured body 26 reverse rotations are worked above repeating, and can record the angular error of measured body 26 reversed turnings.Can measure big angle arbitrarily with this measuring method.
In above-mentioned measuring method, the rise of last fluted disc 2 and fall light beam (energy) loss that action can cause the target mirror to return produces and measures unstablely, even interrupts measuring, as shown in Figure 3.A is a normal condition among the figure, returns entrance pupil 25 by the laser beam that emergent pupil 24 penetrates fully after target Mirror 23 reflections.B is the situation that last fluted disc rises among the figure, owing to rise distance h, the laser beam of returning can not enter entrance pupil 25 fully, and the measurement data instability is to such an extent as to when the excessive laser angle interferometer of light beam loss can not normally receive, measure failure.
The wide-angle measuring system of laser angle interferometer and multiteeth indexing table combination, the measurement range is big, precision is high, easily is automated, and is very useful measuring system.But, because the lifting action of fluted disc on the multiteeth indexing table causes the light beam loss, causing and measure instability, even make the measurement failure, this is the major defect of this measuring method.
Summary of the invention:
The purpose of this invention is to provide a kind of simple in structurely, measure the multiteeth indexing table device of stable not lifting of table top.
The present invention is achieved in that
The multiteeth indexing table device of not lifting of table top of the present invention, lower tooth disk 1 is connected with pedestal 5, last fluted disc 2 lower ends and lower tooth disk 1 engagement, there is the circumferential gearing 4 of axial jacking gear 14 and level to be in transmission connection on the pedestal 5 with last fluted disc 2, last fluted disc 2 is connected by the coaxial table top 10 of diaphragm 8 and last fluted disc, table top 10 is rotatably assorted with pedestal 5, and axle center and table top that target mirror 23 is positioned at table top 10 are connected.
The coaxial connector 9 of the upper surface of last fluted disc 2 and last fluted disc is connected, connector 9 is fixed with diaphragm 8 inner rings, the outer ring of diaphragm 8 is connected with table top 10, and the above and below of the periphery of table top 10 is rotatably assorted with the limiting plate 6 that is connected with pedestal 5 with pedestal 5 by ball collar 7 respectively.
Described diaphragm 8 is the disk or the annulus in a jagged or hole.
Described diaphragm 8 is a several piece, arranges along the circumferentially even of last fluted disc 2.
The present invention is used for accurate measurement of angle, the wide-angle measuring system that is particularly useful for the combination of laser angle interferometer and multiteeth indexing table, because not lifting of table top has been avoided the laser beam energy loss to cause and has been measured instability even make the fault of measuring failure, has improved the measurement reliability.
