The repetitive positioning accuracy of industrial robot in high-speed motion situation is in order to characterize the repeatability of robot end location, and movement locus precision is the important parameter that characterizes robot motion's control performance.The various advanced technologies such as laser interference ranging technology, detecting technique, precision machinery technology, computing machine and control technology, modern numerical calculation theory that laser tracker is integrated, can carry out to space movement target the 3 d space coordinate of real-time follow-up and measurement target, there is high precision, high-level efficiency, real-time follow-up, the feature such as quick for installation, easy and simple to handle, be applicable to very much industrial robot motion precision and path accuracy test.In the application of laser tracker, target is very important on the impact of measuring accuracy, and target profile is spherical conventionally, and inside is 3 mutually perpendicular catoptrons.If the angle point of three catoptrons and the center of ectosphere do not overlap or 3 mutual out of plumb of mirror surface all can cause error, catoptron can not rotate around self optical axis simultaneously.For the kinematic accuracy and path accuracy test of industrial robot, the target that robot will carry laser tracker carries out high-speed motion, follow the tracks of the needs of actual condition simultaneously, on the basis of motion, also to add the swing of upper frequency, and in the gauge measurement system of laser tracker, only have by magnetic suction disc and fix target.In the time that industrial robot high-speed motion is measured, be easy to occur the deflection of target in magnetic suction disc, affect measuring accuracy.If magnetic suction disc base position also exists some greasy dirts or iron filings etc. to affect the foreign material of magnetic force effect, magnetic suction disc and target ball are thrown away by the robot of high-speed motion possibly, now target cannot reuse, and cause larger economic loss, delay test process.Therefore the accuracy test during for industrial robot high-speed motion, is badly in need of a kind of laser tracker target protective device of design, and can be connected with measured equipment is convenient.
Summary of the invention
Described in background technology, the purpose of this utility model is to provide a kind of laser tracker target protective device, and target first wife's magnetic force suction base is fixed on to device inside; For preventing from being rigidly connected, target is caused to damage, between rigid connector and target, added flexible protective, can carry out very easily the flexible protective of target and fixing, bottom of device arranges installation threaded hole, is easy to and being fixedly connected with of equipment under test.After the link position of this device on equipment under test is fixing, the coordinate system translation function carrying in conjunction with laser tracker software, can very easily the laser tracker coordinate system of target fixed position be transformed into below industrial robot coordinate system, be easy to last phase tidying up and the analysis of measurement data, meet the kinematic accuracy test request of industrial robot in high-speed motion (comprising swing) situation completely.
To achieve these goals, the utility model is achieved through the following technical solutions:
A kind of laser tracker target protective device; mainly formed by laser tracker target (1), target flexible protection (2), the circumferential protective device of target (3), magnetic force suction base (4), bottom erecting device (5); wherein: target flexible protection (2) is enclosed within the spheroid outside of target; the circumferential protective device of target (3) is made up of two mounting blocks, by bolt, two mounting blocks is fixed on to the outside of target flexible protection (2).Magnetic force suction base (4) is connected with the lower end sphere absorption of laser tracker target (1); magnetic force suction base (4) sinks to the inside of bottom erecting device (5); bottom erecting device (5) is connected by the circumferential protective device of bolt and target (3), thereby the locus of laser tracker target (1) is fixed.By the upper reserved equidistant threaded hole of bottom erecting device (5), the complete laser tracker target protective device of assembling can be connected with Devices to test.
Described target flexible protection (2) can be made up of sponge, flannelette etc.
After two mounting blocks of the circumferential protective device of described target (3) are fixedly connected with, a spherical cavity concentric with laser tracker target (1) of inner composition.
The installation groove of magnetic force suction base (4) is offered in the upper surface center of described bottom erecting device (5), circumferential and magnetic force suction base (4) transition fit of groove, and depth of groove is slightly less than the thickness of magnetic force suction base (4).
The nuts and bolt head of described all bolts junction all needs to sink to corresponding intrument inside.
Owing to adopting technique scheme, the utlity model has following advantage and effect:
1, between the circumferential protective device of target of the present utility model and target, dosed target flexible protection, ensured can not cause damage to target after target circumferential position closely connects;
2, the spherical cavity concentric with laser tracker target of the inner composition of the circumferential protective device of the utility model target, even can realize target disengaging magnetic force suction base time, also can be limited in, in cavity, preventing that it from surprisingly dropping;
3, the depth of groove of the utility model bottom erecting device is slightly less than the thickness of magnetic force suction base, can when with the circumferential protective device assembling of target, jointly apply certain pretightning force by coupling bolt and magnetic force suction base, realize laser tracker target fixing in whole locus;
4, simple in structure, the easy accessibility, economical and practical of the utility model laser tracker target protective device, the risk of laser tracker target accidental fall can effectively prevent high-speed motion accuracy test time.
