Embodiment
Below in conjunction with the drawings and specific embodiments a kind of axial workpiece pick-up unit of the present utility model is further described.
Scheme mechanical, electrical, the light combination that system adopts, the employing mechanical technique is finished the general structure design of instrument and is realized straight line and rotatablely move, adopt optical technology to realize the detection of Z-direction, X-direction distance and the anglec of rotation, adopt electronic technology to finish control and the data acquisition of instrument, adopt virtual instrument technique to carry out analysis and the processing of data in conjunction with computing machine, and with close friend's interface display testing result.
1. detection and location device
Workpiece adopts two top location, must guarantee during installation that two top central points on same horizontal line, in maximum sliding scale, guarantee that its error is less than 0.0015mm.The left side tailstock is fixed, and the right side tailstock can slide along guide rail, can realize the location of different length part like this.
2. the rotation of workpiece and circumference calibration control
Need be rotated during workpiece sensing, for realizing this function, the left side tailstock be improved: the boring of tailstock center pit is big, and carry out grinding, make its error control in 0.001mm.Two precision bearings are installed in the hole, are guaranteed that alignment error is in 0.0015mm.With in the top bearing of packing into, by driven by motor, can realize top rotation again.Adopt the end face fixed conveyor top, its edge of a knife can be fitted on the left side of workpiece closely, forms good grabbing and makes a concerted effort, and just can drive workpiece with top rotation.The circle code-wheel is installed in top left side, is realized the circumference calibration, certain angle of whenever being separated by is sent a signal, carry out an X-direction data acquisition, according to the closure principle of measuring, each shaft part is all carried out the calibration collection of whole circumference, to reduce Acquisition Error.
3.Z direction of principal axis motion control and grating chi are installed
Along Z-direction two precise guide rail that are arranged in parallel, guarantee during installation that the parallelism error of two guide rails in maximum travel limit is less than 0.0015mm.Ball screw assembly, is installed in the middle of the guide rail, and is linked to each other with the guide rail slide block, by the driven by motor ball-screw, thereby drive guide rail slide block move left and right.According to the abbe ' s principle of measuring, near the position under the detecting head center grating chi parallel with guide rail is being installed, and its scale is linked to each other with the guide rail slide block, then can measure the displacement of detecting head Z direction, realize that Z-direction detects.
4.X direction motion control and grating chi are installed
Be arranged vertically the precise guide rail of two X-directions above the Z-direction precise guide rail, the parallelism error that at first will guarantee two guide rails in maximum travel limit during installation is less than 0.0015mm, and the error of perpendicularity of two pairs of guide rails is less than 0.0015mm about its less important assurance.Detecting head is installed in guide rail slide block top, makes detecting head center and the two top lines of centres contour, and the height error that both install should be less than 0.0015mm.According to abbe ' s principle, in the middle of two guide rails, install one the grating chi, its scale is linked to each other with the guide rail slide block, can measure the displacement of X-direction, realize that X-direction detects.During detection, at directions X detecting head is contacted with the workpiece bus, can design one group of fixed pulley, hang weight, drive detecting head and closely be attached on the surface of workpiece.Because the size of gravity is constant, the contact force of detecting head and workpiece keeps constant substantially in the time of can guaranteeing to detect, and improves accuracy of detection.
During detection, part with two top positioning after, directions X uses gravity installation, make detecting head be attached on the bus of workpiece with constant contact force, the Z direction is used ball screw assembly, to drive detecting head and is axially moved, and whenever at intervals detecting head stops Z-direction and moves, and workpiece rotates a circle, adopt SDC-5 data collecting card certain angle of whenever being separated by to carry out the data acquisition of an X-direction, can collect X-direction (radius R), circumferencial direction (angle θ) and three data p of Z-direction (apart from Z) like this
Ij(Ri
j, θ i
j, Z
j) (wherein i represents angle-differentiated, i=1,2,3 ... n; J represents Z-direction detection position number, j=1,2,3 ... N; ), the data transmission of gathering in computing machine, is carried out data analysis with Virtual instrument LabVIEW and handled and can obtain testing result, and with close friend's interface display.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
