Specific embodiment
Below by specific embodiment, the invention will be further described, and following embodiment is descriptive, is not limit
Qualitatively, it is impossible to which protection scope of the present invention is limited with this.
A kind of discontinuous hole twist measuring instrument is made of " V " type fixture 16, retaining mechanism 1, digital dipmeter 5, locking
Mechanism is vertically arranged at " V " type fixture center, and Digital Dipmeter is horizontally placed on side on " V " type fixture.
" V " type fixture is made of base portion 6, dove-tail form positioning region 7；Dove-tail form positioning region is symmetrically connected under base portion
Fang Bingyu base portions are made as one.Base portion both ends and dove-tail form positioning region both sides are hollow-core construction, in dove-tail form positioning region
Between formed " V " type groove 4.Base portion, side are formed with mounting boss 3." V " type groove, angle are 60 degree.
Retaining mechanism, by handle 8, eccentric wheel 9, eccentric connector 10, upper expander 13, lower expander 15, expander 14,
Connecting rod 11, link rod sleeve 12 form；Link rod sleeve is set to base portion center, and connecting rod is plugged in link rod sleeve, small end
Eccentric connector, eccentric wheel, handle are sequentially connected, connecting rod middle part, lower part set gradually expander, expander, lower expander.
Expander is circular tube shaped component, and both ends tube wall is formed with multiple U-typed notches, and the present embodiment is six U-typed notches.Upper control
Device processed, lower expander, structure is identical, is made of cylinder tail portion, conical nose and is made as one, center is formed with through-hole.
The present invention operation principle be：
When detecting the twist of the discontinuous mounting hole of round steel pipe, steel pipe 2 is placed in the corresponding positions of measuring table first
It puts.Then, " V " type fixture is placed in steel tube surface, connecting rod is inserted into together with lower expander, expander, upper expander on steel pipe
In detected hole, closely it is connect with steel tube surface by retaining mechanism.During locking operation, handle is moved with hand, eccentric wheel around
Axis is raised above in the connecting rod that link rod sleeve top surface rotates and drives eccentric connector and connect with it, at this point, under connecting rod drives
The upward top pressure expander of expander and upper expander, due to being formed with multiple " U-shaped notches " on the tube wall of expander both ends, by
When upper and lower expander squeezes, slightly expand outward naturally, make expander outer wall and steel pipe hole hole wall close contact；Meanwhile " V "
Type fixture is tightly stuck on outer wall of steel pipe under the action of link rod sleeve and lower expander；It at this time can be by being installed on " V " type card
Digital dipmeter on tool reads the torsion angle value in discontinuous hole.
Although disclosing the embodiment of the present invention and attached drawing for the purpose of illustration, those skilled in the art can manage
Solution：Do not departing from the present invention and spirit and scope of the appended claims in, it is various replace, change and modification be all it is possible,
Therefore, the scope of the present invention is not limited to embodiment and attached drawing disclosure of that.
