Abstract
The utility model relates to a material bending compression-proof tester, which is characterized in that a tester support is provided with a central distance adjustment mechanism which comprises a silk pole/ a nut pair, a hand-wheel and a support which is fixed to a base. One terminal of the silk pole rotation-cooperates with the support, and the terminals are fixed to the hand wheel. The silk pole is provided with two sections of worms with equal pitch but reverse spiral directions. Two supports are respectively provided with screws cooperating with two sections of worms and cooperate with the silk pople. The utility model has the advantages of high symmetry of supports and high central distance precision, real and reliable testing data and high operation efficiency.
Description
Technical field
The utility model relates to Material Testing Machine, especially a kind of material bending compression testing machine.
Background technology
When material was done bending or compression test, by a pair of bearing support, according to code requirement, two bearings should symmetrical be arranged in the both sides of pressure head perpendicular bisector, and promptly centre distance equates; The test specimen of heterogeneity, size, bearing centre distance are also different, must on-the-spotly adjust.Existing material bends compression test, and the centre distance adjusting mechanism of test specimen bearing is not set, and is that the armrest wage adjustment is whole, and symmetry and centre distance precision are difficult to guarantee, influence the authenticity and the reliability of test figure; And the manual setting operation is loaded down with trivial details, needs repeatedly to adjust inefficiency repeatedly.
The utility model content
The purpose of this utility model is intended to overcome the shortcoming of existing bending compression testing machine, and a kind of bending compression test with centre distance adjusting mechanism is provided, and can overcome the shortcoming of existing bending compression testing machine.
Technical solution of the present utility model is:
A kind of material bending compression testing machine, comprise base, vertically be arranged in the guide pillar on the base, the crane that is slidingly matched with the guide pillar lifting, be arranged in the hydraulic cylinder on guide pillar top, its piston rod connects crane, is arranged in a pair of bearing that is used to support test specimen on the base, and it is characterized in that: described bearing has the centre distance adjusting mechanism.
The centre distance adjusting mechanism of described bearing should and prop up by screw mandrel/pair of nut, handwheel and be configured to, support is fixed on the base, one end of screw mandrel cooperates with the support revolution, the affixed handwheel in termination, have two sections on the screw mandrel pitch is identical and screw thread that the hand of spiral is opposite, two bearings have respectively and two sections adaptive screws of screw thread of screw mandrel, and screw mandrel cooperates with bearing, constitute screw mandrel/pair of nut.
The testing machine of said structure, owing to be provided with the centre distance adjusting mechanism, bearing symmetry and centre distance precision height, test figure is true, reliable, high efficiency.
Description of drawings
Fig. 1 is a kind of structural drawing (resistance to compression) of this testing machine
Fig. 2 is the another kind of structural drawing (bending) of this testing machine
Embodiment
Referring to Fig. 1: this testing machine comprises base 1, guide pillar 2, crane 8, hydraulic cylinder 10, and its piston rod 9 connects cranes 8, test specimen bearing 4.
Different with existing testing machine, the bearing 4 of this testing machine has been set up the centre distance adjusting mechanism, this mechanism is made of screw mandrel 3, handwheel 11 and support 12, support 12 is fixed on the base 1,12 revolutions of one end of screw mandrel 3 and support cooperate, and handwheel 11 is fixed in the end of screw mandrel 3, have two sections on the screw mandrel 3 pitch is identical and screw thread 3-1 and 3-2 that the hand of spiral is opposite, two bearings 4 are processed with respectively and two sections adaptive screws of screw thread of screw mandrel, cooperate with screw mandrel.Assembly center is during apart from adjusting mechanism, two bearings 4 should with this machine perpendicular bisector symmetry.
The work engineering of this testing machine is as follows:
Compression test
Referring to Fig. 1: during compression test, pressure head 7 adopts horizontal pressure foots, supporting head 5 differences of two bearings 4, and an arc head, another is the pyramid head.At first adjust the centre distance of two bearings 4, make it to meet the requirement of test specimen.Because two bearings 4 are symmetrical with this machine perpendicular bisector, in need not looking for, need only adjust the pivot distance of two bearings 4.Rotate handwheel 11, drive screw mandrel 3 and rotate, driving support seat 4 is subjected to displacement, because the spiral of thread segment 3-1,3-2 is opposite, bearing 4 take place by the screw mandrel stage casing to two ends disperse or by two ends to stage casing convergent displacement, adjust repeatedly, measure, meet the requirement of test specimen until the pivot distance of two bearings 4; Because the pitch of thread segment 3-1,3-2 equates that the velocity of displacement of two bearings equates that the centre distance of any time equates that also as long as pivot distance meets the requirements, centre distance must meet the requirements.After centre distance is adjusted, again test specimen 6 is placed on the bearing 4, can carry out compression test routinely.
Cripping test
Referring to Fig. 2, with the difference of compression test only be: during cripping test, pressure head 7 adopts the arc heads, and the supporting head 5 of two bearings 4 is all used the arc head, and all the other are identical, repeat no more.
