Abstract
An active clamping head of Young's modulus gauge is composed of core bar, clamping head jacket and clamping head cap to make measured steel wire be set at center of clamping head for easy operation and accurate measurement.
Description
One, technical field
The present invention relates to the manufacturing technology of modulus measurer, particularly relate to the manufacturing technology of steel wire active chuck in this measuring instrument.
Two, background technology
Steel wire to be measured in the modulus measurer must be fixed with two chucks, one is fixed chuck, another is an active chuck, wherein the technical requirement of fixed chuck is low, be easy to realize, yet the technical requirement of active chuck wherein is then very high, and desirable active chuck should be the center that can exactly the steel wire of 1 millimeter of diameter less than be sandwiched in steadily chuck; Chuck only depends on manually without instrument and just can shift one's position up and down easily at any time; Chuck becomes uniform gap to cooperate with the hole wall of optical lever support plate.None can reach above-mentioned effect the at present known active chuck that is used for modulus measurer, wherein steel wire does not occupy the chuck center, must be during the chuck folding by instrument, chuck upper and lower position conversion difficulty, the hole wall of chuck and plate produces point-like or the wire contact friction is its common fault.And these problems not only cause instrument Installation and Debugging difficulty, the more important thing is the error that has increased experimental result.
Three, summary of the invention
The objective of the invention is for modulus measurer provides a kind of new-type active chuck, with many drawbacks of the existing active chuck of thorough solution.
The object of the present invention is achieved like this: get a segment length 30～35mm, the brass bar of diameter 15～16mm, on the center line of rod, vertically bore the through hole of an aperture 0.8mm, 1/2 part that with length is rod then is with the reduced 3～4mm of lathe with this section, and this section longitudinally driven the keyway of a dark 2mm, one section termination chamfering to being left then becomes 5 * 45 °, with wire cutting machine tool this section longitudinally is cut into uniform pintongs again, the width in otch slit is less than gauge of wire to be measured, constitute plug with this, getting a segment length again is 45～50mm, diameter is rod iron or the brass bar of 21mm, boring an aperture on the heart line therein is the through hole of 0.8mm, hole with the one end enlarges then, and one bar shaped key longitudinally is installed at the hole wall of reaming part, hole and key after the expansion are become movingly with the small end and the keyway of plug, long 1～the 3mm of one section the length that the depth ratio plug of reaming is relatively little, an end of corresponding reaming is carved into screw thread on the periphery of rod, the length of threaded portion is 1/2 of rod length, constitute the chuck cover with this, getting a segment length then is 35～40mm, diameter is rod iron or the brass bar of 21mm, boring a diameter on the heart line therein is the through hole of 13～14mm, and 2/3 length in hole is carved into screw thread, make the diameter of this screw thread consistent with the screw thread that chuck puts, and make between threaded hole and stomidium and become conical surface transition, constitute the chuck cap with this, at last steel wire to be measured is passed the chuck cap successively, plug and chuck cover, behind the small end insertion chuck cover with plug, by the screw thread between chuck cap and the chuck cover plug is locked, steel wire then is clamped on the center line between the pintongs of plug again.
Adopt such scheme, can receive following remarkable result:
1, because plug one end is uniform pintongs state, and the other end is whole, thus can opening and closing can not misplace each other again freely between the pintongs of plug, thereby guaranteed the stability of steel wire locking process;
2, since the slit between the pintongs of plug under non-locking state less than gauge of wire, between two parties be unlikely to embed in the lobe break joint so can guarantee steel wire;
3,, can need not use any instrument again reliably with steel wire locking by right-hand man's difference turn chuck cover and chuck cap;
4, by turn chuck cover and chuck cap, can make things convenient for upper and lower freely mobile chuck and it is lock onto required any position;
5, owing to can guarantee that steel wire occupies the center line of chuck, thereby avoid the crooked of chuck, finally eliminated the point-like of chuck periphery and optical lever support plate hole wall or the hidden danger of wire contact friction.
Four, description of drawings
Accompanying drawing is the structural drawing of modulus measurer active chuck.
1. plugs, 2. keys, 3. chucks overlap 4. chuck caps among the figure.
Wherein the integral end of plug inserts in the chuck cover, and the chuck cap with become threaded connection between chuck overlaps.
Five, embodiment
Get a segment length 30mm, the brass bar of diameter 15mm, on the center line of rod, vertically bore the through hole of an aperture 0.8mm, 1/2 part that with length is rod then is with the reduced 3mm of lathe with this section, and this section longitudinally driven the keyway of a dark 2mm, termination chamfering with this section becomes 5 * 45 ° then, one section that will be left with wire cutting machine tool more longitudinally is cut into uniform pintongs, the width in otch slit is less than gauge of wire to be measured, constitute plug with this, getting a segment length again is 45mm, diameter is rod iron or the brass bar of 21mm, boring an aperture on the heart line therein is the through hole of 0.8mm, hole with the one end enlarges then, and one bar shaped key longitudinally is installed at the hole wall of reaming part, hole and key after the expansion are become movingly with the small end and the keyway of plug, one section the long 1mm of length that the depth ratio plug of reaming is relatively little, an end of corresponding reaming is carved into screw thread on the periphery of rod, the length of threaded portion is 1/2 of rod length, constitute the chuck cover with this, getting a segment length then is 35mm, diameter is rod iron or the brass bar of 21mm, boring a diameter on the heart line therein is the through hole of 13mm, and 2/3 length in hole is carved into screw thread, make the diameter of this screw thread consistent with the screw thread that chuck puts, and make between threaded hole and stomidium and become conical surface transition, constitute the chuck cap with this, at last steel wire to be measured is passed the chuck cap successively, plug and chuck cover are behind the small end insertion chuck cover with plug, by the screw thread between chuck cap and the chuck cover plug is locked, steel wire then is clamped on the center line between the pintongs of plug again.
