Abstract
The utility model discloses a clamp for a sectional material torsion test. The clamp is mounted on a torsion testing machine, and comprises a base and an insert; the base is cylindrical; a plurality of threaded holes are uniformly formed in one end surface of the base circumferentially, and connected with and fixed on the torsion testing machine through bolts; a rectangular groove is formed in the centre on the other end surface of the base; the insert is a rectangular solid, and is matched with and inserted in the rectangular groove in the base; a positioning groove which is completely matched with the section shape of a sectional material to be tested is formed in the centre on the outer end surface of the insert. Different positioning grooves are formed in the insert to match sectional materials of different sizes; the clamp has the characteristics of convenient operation and simple positioning.
Description
Technical field
The utility model relates to a kind of fixture, and being specifically related to is a kind of section bar torsion test fixture.
Background technology
Torsion test is the conventional means that the mechanics of materials detects, and torsion testing machine is also more and more at present, and torsion testing machine mainly comprises clamping fixture seat, specimen holder etc.But existing torsion testing machine is mainly applicable to the twisting test of the solid sample of standard and wire rod etc., the type of sample is extremely limited to.
Along with market development, more and more for the twisting test demand of section bar at present, hollow tube, odd-shaped cross section tubing get more and more, and traditional torsion testing machine is difficult to these non-standard samples to carry out twisting test.While using existing equipment to carry out twisting test to section bar, holding force is excessive may cause subsiding of section bar retained part, and too small can the causing again while torsion of holding force skidded.Therefore,, for the twisting test of section bar, design new test fixture very necessary.
China Patent No. 201220049405.0 discloses a kind of torsion testing machine twisting fixture, it comprises a pair of upper and lower fixture, upper and lower clamp structure is identical, include a clamping fixture seat and an intermediate plate piece, on clamping fixture seat, have the dovetail groove of one section of sealing, intermediate plate piece bottom and dovetail groove shape adaptation are also located in dovetail groove, and intermediate plate piece surface has wedge shape draw-in groove, and is provided with alternate groove in draw-in groove two sides.This device can effectively improve holding force, highly versatile, but section bar is still likely caused to subsiding of bare terminal end, be difficult to use in the fixture of section bar twisting test.
China Patent No. 201220515693.4 discloses a kind of pipe fitting torsion testing machine, and it comprises servomotor, reductor, primary planet fixture, bearing, secondary planetary fixture, driving lever, tailstock, sensor, line slideway, frame, coupling shaft, catch etc.Coupling shaft links together eccentric semicircle clamp and outer rotor to form rotation fixture block with rectangular spline, and coupling shaft and catch are rotationally connected, and rotation fixture block is uniformly distributed in turning axle by catch.This device can easily clamping sample, but complex structure, and be difficult to be suitable for for section bar.
Summary of the invention
The purpose of this utility model is to provide a kind of section bar torsion test fixture, have easy to operate, locate the features such as simple.
For achieving the above object, the technical solution of the utility model is:
A kind of section bar torsion test fixture, is installed in twist machine; It comprises, pedestal is cylindrical, and pedestal one end face some threaded holes that are uniformly distributed along the circumference, are connected and fixed by screw and twist machine, and other end central authorities establish a rectangular recess; Inserting, is rectangular parallelepiped, and rectangular recess big or small and described pedestal matches, and is embedded in this rectangular recess, and its outer face central authorities establish a detent fitting like a glove with the cross sectional shape of section bar to be reversed.
Further, the described surface working of inserting has two threaded holes, and being provided with conveniently to insert installs and the bolt taking out.
Described in the utility model inserting is a rectangular parallelepiped, and size matches with the rectangular channel of pedestal.The one side of inserting has a locating slot fitting like a glove with the cross sectional shape of section bar to be reversed, and a segment distance in locating slot can just be inserted in the one end that can guarantee section bar, the other end similarly, thereby complete the location of section bar in twist machine.For the section bar of different size specification, can on inserting, process different locating slots and coordinate with it.If section bar specification to be reversed is more, locating slot cannot all process one insert on, now can be processed with inserting of different locating slots and realize by replacing the clamping of section bar.The surface working of inserting has two threaded holes, can erection bolt so that the installation of inserting and taking-up.
Compared with prior art, the utility model has the advantages that:
(1) can process the pedestal matching with it and not change and insert according to different twist machine models, versatility be better.
(2) inserting of fixture can be changed at any time, and with the section bar of clamping different cross section, and positioning stablity is reliable.
(3) only have pedestal and two parts composition of inserting, simple in structure, with low cost, convenient and swift.
Accompanying drawing explanation
Fig. 1 be the utility model embodiment structural representation.
Fig. 2 is the side view of pedestal in the utility model embodiment.
Embodiment
Referring to Fig. 1, Fig. 2, a kind of section bar torsion test fixture of the present utility model, is installed in twist machine; It comprises, pedestal 1 is cylindrical, and pedestal 1 one end faces some threaded holes that are uniformly distributed along the circumference are connected and fixed by screw 2 and twist machine, and other end central authorities establish a rectangular recess 11; Inserting 3, is rectangular parallelepiped, and the rectangular recess 11 of big or small and described pedestal 1 matches, and is embedded in this rectangular recess 11, and its outer face central authorities establish a detent 31 fitting like a glove with the cross sectional shape of section bar to be reversed.
Further, described 3 surface working of inserting have two threaded holes, and being provided with conveniently to insert installs and the bolt 4 taking out.
Pedestal is connected and fixed by screw and twist machine, insert and be arranged in the rectangular recess of pedestal, detent can be processed into difformity according to section bar cross section, when design, will note determining according to cross sectional shape the centre of form in cross section, thereby while guaranteeing to reverse, the centre of twist of section bar is positioned at the center of base disc.
The present embodiment, take square tube torsion as example, at center processing and the square detent that square tube size matches inserted, is inserted into the two ends of square tube in the square groove of inserting respectively before test, thereby realizes square tube location.
Claims (2)
1. a section bar torsion test fixture, is installed in twist machine; It is characterized in that, comprise,
