Embodiment
A kind of multiparameter non-contact on-line detection device for large scale ladder profile shaft, as shown in Figure 1, Figure 2, Figure 3 shows, comprise the clamp rotating mechanism of base 1, portal frame 2, loading and feel trim actuator, workpiece lifting mechanism, workpiece and can detect the testing agency of five kinds of parameters of shaft, these five kinds of parameters comprise: diameter, diameter run-out, length, cylindricity and face runout.Wherein portal frame 2 consists of column and crossbeam; Load with I/O closed slide I 3, I/O closed slide II 4, circular arc suspension hook I 21, circular arc suspension hook II 22 and suspension hook drive motor I 23, the suspension hook drive motor II 24 of feel trim actuator by workpiece and form; Workpiece lifting mechanism consists of hydraulic cylinder 5, V-type bearing 6; The clamp rotating mechanism of workpiece is comprised of the headstock 7, tailstock 8; The testing agency of five kinds of parameters that can detect shaft by measuring diameter, diameter run-out, the length of axle, four parameter detecting mechanisms of four kinds of parameters of cylindricity and a kind of parameter detecting mechanism of parameter that can measure the face runout of axle form.
Described base 1 is cast structure body, upper plane at base 1 directly processes for placing the fixed closed slide 30 of the headstock 7 and tailstock 8, this fixed closed slide 30 can guarantee the headstock 7 and tailstock 8 moving axially along measured axis, on base, plane stage casing is processed with open slot, and workpiece lifting mechanism is installed in open slot.
Described portal frame 2 consists of column and crossbeam.The lower plane of crossbeam be positioned at measured axis directly over, be provided with one can along the axially-movable of measured axis move axially guide rail 16, move axially and on guide rail 16, dispose a grating scale I 25 and can realize the axial drive motor I 17 of four parameter gauge head I 14, a four parameter side II 15 transverse shiftings, axial drive motor II 18; Distolateral at two that move axially guide rail 16, moving radially guide rail I 28, moving radially guide rail II 29 of moving guide rail 16 perpendicular to axial direction is installed, and each moves radially and on guide rail, disposes respectively a grating scale and the radial drive motor moving radially that can realize a parameter gauge head.
The main function of described loading and feel trim actuator is that measured axis is put into above the workpiece lifting mechanism in the middle of plane on base 1 and will above the Zhou Cong workpiece lifting mechanism being completed, be taken off.Input closed slide is positioned at a side of base 1, the input end away from base at input closed slide disposes circular arc suspension hook and a suspension hook drive motor, these two circular arc suspension hooks are arranged on same rotation axis, this rotation axis is controlled rotation by this suspension hook drive motor, thereby realizes the rotation of two circular arc suspension hooks.Measured axis does not enter before base 1, first by two circular arc suspension hooks, measured axis is hooked to the input end that is placed on input closed slide, keeps static.From the input end of input closed slide, to base 1, be designed to the downward gradient of 5 °, so just can guarantee, when keeping static measured axis to rotate while putting down at circular arc suspension hook, due to Action of Gravity Field, measured axis can slowly be rolled in the workpiece lifting mechanism in the middle of base 1.And output closed slide is arranged on the opposite side of base 1, dispose same circular arc suspension hook and suspension hook drive motor, but be from input the different of closed slide, two circular arc suspension hooks and a suspension hook drive motor of output closed slide are arranged on the one end near base 1, this one end is higher than the other end (being called output terminal) of output closed slide simultaneously, that is to say after measured piece detects, by circular arc suspension hook, from the V-type bearing 6 of workpiece lifting mechanism, hooked, be put on output closed slide, when suspension hook drive motor is controlled after suspension hook rotation, measured axis can roll out along the output closed slide of 5 ° above base.
The function of described workpiece lifting mechanism is that measured axis is risen or put down, and is vertically mounted in the medial launder of base.Workpiece lifting mechanism consists of vertically disposed hydraulic cylinder 5 and the V-type bearing 6 by two V-type derbies and a sheet metal assembling.After measured axis is rolled on V-type bearing 6, by hydraulic cylinder 5, control the height of V-type bearing 6, measured axis plane from base 1 is raised to the clamping height of measured axis, after clamping, V-type bearing 6 is dropped to and is not affected the height that measured axis rotates by control again.After measured axis detects, V-type bearing 6 again rises to the clamping of measured axis and highly catches measured axis, then with measured axis, drops to together plane on base 1.
The fixture of described workpiece and rotating mechanism consist of the headstock 7 and tailstock 8 two parts, and the effect of this mechanism is exactly that measured axis is clamped or decontroled, and guarantee that measured axis is according to certain rotational speed.The headstock 7 is placed on above the fixed closed slide 30 that on base, plane directly processes with tailstock 8.The headstock 7 disposes respectively and is parallel to the headstock of plane top 9 and tailstock center 10 on base with tailstock 8, and the headstock 7 is separately installed with a top hydraulic cylinder that is parallel to plane on base 1 with tailstock 8 inside.The headstock top 9 and tailstock center divide 10 Tong Guo not control flexible by two top hydraulic cylinders.A tailstock center rotational drive motor 11 is also installed on tailstock, tailstock center 10 is connected with tailstock center rotational drive motor 11 by spring coupling, after measured axis is by two top clampings, this tailstock center rotational drive motor 11 toply rotates with clamped measured axis together by controlling.
The described testing agency of detecting five kinds of parameters of shaft comprises again Liang Zhongfen testing agency, Yi Gefen testing agency is four parameter detecting mechanisms of the diameter that can measure axle, diameter run-out, length, four kinds of parameters of cylindricity, this four parameter detecting mechanism by moving axially guide rail 16, be suspended on this and move axially guide rail 16 two four parameter gauge heads and two axial drive motor above and form.Another minute testing agency is the parameter detecting mechanism that can measure the face runout of axle, and this parameter detecting mechanism moves radially guide rail, is suspended on each two parameter gauge heads and two radial drive motor above radial guidance and forms by two.
During actual use, first the parameter detecting mechanism that can measure the face runout of axle carries out the measurement of face runout amount to the measured axis under rotary state, at this moment two parameter gauge heads that hang on two radial drive Electric Machine Control guide rails move to respectively the active position that face runout amount can detect, after obtaining the data of face runout amount, two parameter gauge heads are respectively by radial drive Electric Machine Control separately, radially move, away from measured axis, moving radially apart from guaranteeing that next step moves axially two four parameter gauge heads that guide rail 16 drives at this moment, middle to both sides passing process from measured axis, a parameter gauge head that is not moved radially guide rail suspension has influence on.
The present invention is applicable to production line Site Detection, its length detection scope: 0～3000mm, precision≤± 10 μ m; Examine of diameter scope Φ 100～Φ 450mm, precision≤± 2 μ m; Radially with face runout accuracy of detection≤0.03mm; Cylindricity accuracy of detection≤0.015mm; Detection speed≤6.5 minute/part.
In the clamp rotating mechanism of workpiece of the present invention and testing agency, the movement of side head is all designed to manually and automatic two kinds of drive patterns, in the situation that drive motor cannot normally be worked, can adopt manual operation to realize the measurement to workpiece parameter.
