Description
Technical field
The invention belongs to the technical field of laser measurement, and in particular to it is a kind of for laser tracker can self adaptation hole
The auxiliary locator in footpath.
Background technology
Laser tracker is a kind of wide range, high-precision industrial instrument, and space movement target can be tracked
And the 3 d space coordinate of target is measured in real time.With high accuracy, high efficiency, can real-time follow-up the features such as, it is adaptable to it is big
The adjunct test of type workpiece and equipped measurement.Laser tracking measurement system is substantially by laser tracking head, controller, Yong Huji
Calculation machine, target ball (reflector) and auxiliary mould cushion block etc. are constituted.
The basic functional principle of laser tracking measurement system is to place one with the direct or indirect way of contact on impact point
Individual target ball, the laser that follower head sends is mapped to and follower head is reflected back toward in target ball.Meanwhile, the laser beam of return is by reception system
Gathered, the integrated data of light path, phase and follower head angle measurement encoder according to laser is used for calculating the three dimensions of target
Position.Follower head has the two degrees of freedom precise rotating platform of orientation and pitching, when target ball is moved in follower head field range, with
Track head can adjust light beam acquiring direction to be directed at target ball in real time.
The target ball of laser tracker is typically directly used for the surface of measurement object, for the survey of the geometric elements such as hole, point, side
Amount is then needed by various auxiliary moulds.Wherein, the measurement of coordinates in hole is main in two kinds of situation, and a kind of is the standard being pre-designed
Location hole, this hole has the standard such as 6mm, 8mm or 10mm aperture, is using the auxiliary mould one-shot measurement of dimension directly
Can obtain the coordinate in hole；Another kind is plain bore, and its size is generally different from above-mentioned specification, is needed along the circumference in hole during measurement
The multiple points of measurement are fitted to the coordinate that a circumference calculates the center of circle again, are achieved in that the coordinate in hole needs the multiple points of measurement
Coordinate carries out calculating operation again, less efficient.In order to a large amount of various sizes of plain bores are quickly surveyed in solving mechanical workpieces
Amount problem is, it is necessary to a kind of auxiliary locator with self adaptation aperture so that for the Kong Junke one-shot measurements of different-diameter
Obtain coordinate information.
The content of the invention
The technical problem to be solved in the present invention is：There is provided one be used for laser tracker can self adaptation aperture auxiliary determine
Position device so that laser tracker can obtain the coordinate information of the measured hole of different-diameter by one-shot measurement, so as to improve
Measurement efficiency.
In order to solve the above-mentioned technical problem, the present invention is realized using following technical scheme：
A kind of laser tracker auxiliary locator in self adaptation aperture, the device can be by changing the equivalent of cylindrical probe
External diameter, realizes the quick measurement to the hole of different-diameter.
The device includes holding billiard table, base, rotor plate, bearing, magnet, reed, bearing pin, gaging hole axle；Wherein：
The described top for holding billiard table is stage body, has the tapered blind hole of fixation measuring target ball in the upper surface of stage body,
The mode of the bottom interference fit of blind hole fills in magnet, is used to hold target ball.The bottom of billiard table is held for boss, under boss
Fang Youyi sections of threaded rod.
The upper surface of described gaging hole axle have one sinking step surface, the diameter of step surface with hold billiard table lower boss
External diameter is consistent, and the outer wall that the center of step surface has a tapped blind hole, gaging hole axle has three grooves for waiting angle annular spread.
The upper surface center of described base has the stepped hole of insertion, and bearing, bearing outer ring and platform can be installed inside it
It is interference fit between rank hole.There is a step cutting pattern face for sinking in the lower surface center of base, step surface bottom there are three
Deng the pin-and-hole of angle annular spread.Pin-and-hole has a counterbore in the upper surface of base.
Described bearing pin have two in the axial direction for installation reed and the groove of rotor plate, the ring of bearing pin and base
The pin-and-hole of shape trench bottom constitutes gap and coordinates.There is the step being relatively large in diameter one end in bearing pin with slot distance farther out.
Described rotor plate has the contact surface being mutually coupled with the groove of gaging hole axle, when the rotation of billiard table respect thereto is held,
There is relative slip, and the inside and outside swing with the rotation for holding billiard table with the groove of gaging hole axle outer wall in rotor plate.
Present invention advantage compared to the prior art is：When the coordinate of the plain bore for needing to measure multiple diameter, nothing
Acquisition central coordinate of circle need to again be calculated by the circumference of multiple measured hole, be to be capable of achieving positioning only by the equivalent external diameter of micromatic setting
And measurement, improve the measurement of coordinates efficiency of plain bore.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is structural representation upward view of the invention.
Fig. 3 is use principle schematic diagram of the invention.
In figure, billiard table 1, base 2, rotor plate 3, bearing 4, magnet 5, reed 6, bearing pin 7, gaging hole axle 8, target ball 9 are held.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
The all parts of the laser tracker auxiliary locator of self adaptation aperture shown in Fig. 1 are：Hold billiard table 1, base 2,
Rotor plate 3, bearing 4, magnet 5, reed 6.Bearing 4 is mounted with the upper surface center stepped hole of base 2 and match somebody with somebody by interference in Fig. 1
Conjunction is fastened, and holding the lower boss of billiard table 1 with the endoporus of bearing 4 there is gap to coordinate.
The sinking step cutting pattern face of the lower surface middle position of base 2 has three pin-and-holes, these three pin-and-holes difference in Fig. 2
Gap is constituted with bearing pin 7 to coordinate, bearing pin 7 is inserted from the upper surface of base 2, until the step of bearing pin 7 is heavy with the upper surface of base 2
Hole contacts in place.After billiard table 1 is held and base 2 is assembled, the axial freedom of bearing pin 7 is by Complete Bind.
Two grooves of bearing pin 7 are respectively mounted reed 6 and rotor plate 3 in Fig. 2.Assembled with base 2 when billiard table 1, gaging hole axle 8 is held
After good, gaging hole axle 8 is in close contact with three rotor plates 3 around its surrounding.Reed 6 is after device is assembled by the following table of base 2
Face circle step edge forces bending so as to provide the pressure of foregoing close contact.
The cylindrical of target ball 9 is fitted on the tapered blind hole inwall for holding the upper surface of billiard table 1 in Fig. 3, and target ball 9 can be by magnet 5
Magnetic-adsorption is lived.The lower surface of base 2 fits to the plane of measured hole, and gaging hole axle 8 is stretched into measured hole, keeps base 2 not turn
In the state of dynamic, billiard table 1 is held in rotation, and the phase of rotor plate 3 is caused under the outline effect of intercoupling of gaging hole axle 8 and rotor plate 3
Gyroaxis to device gradually spreads out, while the putting position of micromatic setting, until all rotor plates 3 withstand measured hole completely
Inwall.Now the axis of device is completely superposed with the axis of measured hole, and the coordinate for measuring target ball 9 using laser tracker can be obtained
Obtain the coordinate of measured hole.
