Summary of the invention
The purpose of this utility model is to provide a kind of can reduce the manual operation error, increase work efficiency and the gear of measuring for cable of measuring accuracy rotates the fixed conveyor device.
The purpose of this utility model realizes by following technological means:
A kind of gear rotation fixed conveyor device of measuring for cable, it is characterized in that: comprise scroll chuck, transmission gear, fixed cover and base plate, fixed cover is arranged on base plate, scroll chuck is arranged between fixed cover and base plate, the sidewall of scroll chuck is installed a transmission gear for driving three movable jaws to move, and this transmission gear is driven by the spacing driving lever be arranged on the fixed cover sidewall; Scroll chuck outer rim coaxial package parcel, install a gear shaft on the sidewall of fixed cover, the front end of this gear shaft is installed a driving gear, and the parcel of this driving gear and scroll chuck outer rim is connected with a joggle; A supporting plate of bottom fixed installation of scroll chuck, the lower end of this supporting plate is rotatably installed on base plate, on this supporting plate, one is made a vertical rotating shaft, and this rotating shaft is installed in the axle center of scroll chuck, and the upper end of rotating shaft adopts lower sheeting of dismantled and assembled mode coaxial package and a upper compressing tablet.
And, described spacing driving lever comprises locating sleeve and hexagonal bearing pin, locating sleeve is arranged on the madial wall of fixed cover, hexagonal bearing pin level is installed in locating sleeve, hexagonal bearing pin outside surface is shaped with two locating slots, installs one on locating sleeve for being inserted into the spring detent of the threaded ball in locating slot; A joystick that is positioned at the fixed cover outside is installed in the rear end of hexagonal bearing pin; Be shaped with an interior hexagonal slotted eye corresponding with the hexagonal bearing pin on transmission gear, the front end of hexagonal bearing pin is inserted in interior hexagonal slotted eye.
And, a fixed cover is installed on the madial wall of described fixed cover, gear shaft is installed in fixed cover by the bearing level, and a control handle is installed in the rear end of gear shaft, and this control handle is positioned at the outside of fixed cover.
And mark line is all made on described fixed cover and scroll chuck surface.
And described upper compressing tablet and lower sheeting adopt wing screw to be arranged in rotating shaft, on this, lower sheeting all is positioned at top, the fixed cover outside.
Advantage of the present utility model and good effect are:
1, this device mainly consists of supposition center of circle mechanism and test piece rotating fixing machine, control the folding of three movable jaws in scroll chuck by the transmission knob, can play the effect in the free voltage grade cable internal diameter supposition center of circle, location, thus solved decentraction in the traditional measurement process problem, reduced the manually-operated error, improved the accuracy of measurement result.
2, this device can plug spacing driving lever fast by interior hexagonal location, thereby has realized the switching between supposition center of circle positioning and selecting test point shelves.After switching, the rotation by rotating shaft realizes horizontally rotating of compressing tablet and test piece, thereby can choose the test value of any radius, any amount, improves accuracy and the measuring speed of measurement result.
3, use this device can at utmost reduce the impact of human factor on measuring, as avoided manually directly controlling test piece, can realize accurately locating fast tested point, can stable being fixed on position to be measured by test piece, can avoid due to measuring error that human factor causes such as detection line width or viewing angles.
4, due to cable conductor in stranded process in theory the definite circle of outward flange approach just roundly, so definite supposition center of circle can be used as the reference value of measurement according to it, obtain valid data.On the basis of having determined the supposition center of circle, add the measurement index of an irrelevance, the interior outer rim maximum radius of random layer and least radius is poor, takes absolute value, divided by the result of radius mean value.This value has reflected the departure degree of each layer with the center of circle, has solved for insulation course and interior outer semiconducting layer thin and thick and evenly still there has been to the cable departed from the center of circle, and uses traditional degree of eccentricity to detect and can't detect its abnormal problem.The theoretical optimal value of this measured value is 0.The qualified threshold value of nominal can be delimited according to actual needs.Therefore use this device can improve rapidly measuring speed and improve and measure precision.
5, the fixed cover of this device and scroll chuck surface all are shaped with mark line, the interior hexagonal slotted eye of making on mark line on scroll chuck and transmission gear has certain angle, therefore when the mark line on fixed cover and scroll chuck surface coincide, can the hexagonal bearing pin be inserted in interior hexagonal slotted eye fast, realize being connected and fixed of hexagonal bearing pin and transmission gear, the design of this mark line has increased the convenience that operation is located, has improved measurement efficiency.
6, the utility model is that a kind of design is ingenious, easy to use, the practical gear of measuring for cable rotation fixed conveyor device, this device combines the supposition center of circle of the internal diameter of semi-conductive layer in three-point fix fast by toothed gearing, the cable test piece is fixed on the supposition center of circle by compressing tablet, get final product each layer thickness and the cable degree of eccentricity of any radius of Quick Measurement, thereby solved the decentraction of choosing of the measurement point that causes due to manually-operated in the traditional measurement, can't choose arbitrarily fast measuring position, measure inefficiency and the not high problems of accuracy of measurement, reduced to greatest extent human error.
