As shown in Figure 1 to Figure 3, according to a kind of supporting tooling detecting camshaft geometrical property of the specific embodiment of the invention, comprise base 1, two guideposts 2, vee-block 3 and knob nuts 41 and screw rod 42 assembly.Wherein base 1 comprises the column sections 11 of both sides and the crossbeam 12 (see Fig. 9) be horizontally set with in these two column sections 11 upper ends, and the inside of each column sections 11 is equipped with vertical pilot hole 13, and the middle part of base 1 is cavity 14.Two guideposts 2 are plugged in the pilot hole 13 of two column sections 11 respectively, and the bottom of these two guideposts 2 is provided with retracing spring 5 (see Fig. 4).Vee-block 3 is strip, and the both sides, bottom of vee-block 3 are separately fixed at the upper end of two guideposts 2.Knob nut 41 and screw rod 42 assembly are located at the middle part of crossbeam 12, and knob nut 41 is in cavity 14, and the upper end of screw rod 42 is connected with the bottom of vee-block 3, and knob nut 41 is used for drive screw 42 and drives vee-block 3 to move up and down.
In such scheme, by arranging two guideposts 2 slided up and down in the both sides of base 1, vee-block 3 is fixed on the upper end of two guideposts 2, namely this vee-block 3 can be used to bearer cams axle 10 (see Figure 11), and the weight of camshaft 10 self leans on the Spring balanced of two retracing springs 5 arranged in the pilot hole 13 of base 1.In addition, by being connected in the corresponding height of screw rod 42 on vee-block 3 and knob nut 41 adjustable vee-block 3 to adapt to the camshaft 10 of different journal diameter.In this programme, the weight of camshaft 10 self leans on the Spring balanced of two retracing springs 5 arranged in the pilot hole 13 of base 1,, length length, weight camshaft more than 15 kilogram large for volume, a people just can operate, in operating process, the hand of operator can leave camshaft, very laborsaving and safety.By being connected in the differing heights of screw rod 42 on vee-block 3 and knob nut 41 adjustable vee-block 3, the camshaft of different journal diameter can be adapted to, applied widely.
As a kind of preferred embodiment, the profile of base 1 is cuboid, and column sections 11 is square column, and crossbeam 12 is dull and stereotyped, and the front side of base 1 inwardly hollows out and forms cavity 14.Preferably, cavity 14 is semicircle.
As a kind of preferred embodiment, the bottom of the through column sections 11 of pilot hole 13, the bottom of column sections 11 is provided with the cover plate 9 (see Fig. 8) for sealing pilot hole 13, and cover plate 9 is fixed by screw 8.
As a kind of preferred embodiment, the upper end of two guideposts 2 has joint flange, and joint flange is fixed by the bottom of screw 7 with vee-block 3.
As a kind of preferred embodiment, the lower end of two guideposts 2 is provided with the mounting hole (see Fig. 8) installing retracing spring.
As a kind of preferred embodiment, the hole wall of pilot hole 13 is provided with stop screw 6 (see Fig. 4), and the sidewall of two guideposts 2 is provided with the stopper slot aimed at stop screw 6.
As a kind of preferred embodiment, the V-arrangement face of vee-block 3 is provided with backing plate.The working surface that backing plate does not damage tested camshaft is set.
Below for certain model camshaft product, illustrate this frock at cam shaft to the application in the detection with diameter run-out project, concrete steps are as follows:
1) by the clean cotton wiped clean of each working surface of camshaft supporting frock and tested camshaft.
2) lock-screw of the movable end base of the deflection instrument of on camshaft platform is unclamped, and move to certain position.
3) camshaft supporting frock is placed in the middle part of deflection instrument, and adjusts the height of vee-block 3 by turn-knob nut 41.
4) between two backing plates camshaft 10 being placed on vee-block 3, and one end of camshaft 10 is shifted onto the stiff end of deflection instrument top near.
5) again adjusted the height of vee-block 3 by turn-knob nut 41, make camshaft center pit lower than top axis about the 0.5 ~ 1mm of deflection instrument, and with hand camshaft 10 one end center hole is pushed into the stiff end of deflection instrument top on.
6) the movable end base lock-screw of another deflection instrument is unclamped, and after being withdrawn into suitable position, after depressing top return handle, again base is retracted certain distance, with lock-screw, movable end base is locked again, and decontrol top handle, make the other end center hole of camshaft 10 enter into the movable end of another deflection instrument top on, now camshaft 10 is only by two conical sliding supports on deflection instrument.Now, camshaft journal has departed from two pad surfaces of camshaft supporting frock, again by the height of turn-knob nut adjustment vee-block 3, interferes to ensure that measuring process backing plate does not rotate with camshaft.
7) with dial gauge by rule method measure cam shaft to diameter run-out project.
8), after measurement terminates, pull down camshaft in reverse order, and by each working surface wiped clean of clean cotton by frock, oil and deposit and preserve.
To sum up, the supporting tooling of the detection camshaft geometrical property of the present embodiment supports vee-block 3 by arranging two guideposts 2 slided up and down in the pilot hole 13 of base 1, the weight of camshaft 10 self leans on the Spring balanced of two retracing springs 5 arranged in the pilot hole 13 of base 1,, length length, weight camshaft 10 more than 15 kilogram large for volume, a people just can operate, in operating process, the hand of operator can leave camshaft, very laborsaving and safety.Meanwhile, by being fixedly connected on the differing heights of screw rod 42 on V-block 3 and knob nut 41 adjustable vee-block 3, the camshaft of different journal diameter can be adapted to, wide accommodation.By designing this supporting tool, coordinate dial gauge can detect the axis of large-scale camshaft and diameter run-out project, handling safety, efficiency is high.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
