Abstract
The invention discloses an automatic resetting device for shear tests. The automatic resetting device is mainly used for achieving an automatic resetting function of aluminum and aluminum alloy rivet wire shear tests. The automatic resetting device comprises a connecting shaft 1, a rubber spring 2, an upper joint 3, a shear auxiliary appliance 4, a lower joint 5 and a flange base 10, which are connected with one another in sequence from top to bottom; the shear auxiliary appliance 4 comprises a cutter 41 and two side plates 42 on the two sides of the cutter 41; the cutter 41 is connected with the upper joint 3 by use of an upper bolt 7; the side plates 42 are connected with the lower joint 5 by use of a lower bolt 8; the lower joint 5 is connected with the flange base 10 by use of a pin 9; the flange base 10 is fixed on a worktable of a testing machine by use of a screw. The automatic resetting device for the shear tests is used for solving the problem that a person is required to operate a testing machine for slow resetting every time after a test is completed in the past, and is capable of avoiding rigid contact and eliminating hidden danger that a sensor is damaged by jacking.
Description
Technical field
The present invention relates to a kind of shear test automatic reset device, specifically a kind of shear test automatic reset device for regulation in standard GB/T3250-2007 " aluminium and aluminium alloy rivet line and rivet shear test method and rivet line riveting test method ".
Background technology
GB/T3250-2007 has specified aluminium and aluminium alloy rivet line and rivet shear (double shear) test method and rivet line riveting test method, in present shear test, after shear test completes, owing to there is no snubber assembly, shearing attaches meeting rigidity feeler while reset, this rigidity contact force is larger, has the situation of bad sensor of top.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of simple in structure, after shear test completes, make to shear and attach the device of avoiding bad sensor of rigidity contact top while reset.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: comprise that the coupling shaft, rubber spring, top connection, the shearing that are connected in turn from top to bottom attach and lower sub, the inside of described rubber spring is fixed with two and adjusts to shear and attach the guide pole of right alignment, and described shearing attaches and comprises that a cutter and two are positioned at the side plate of cutter both sides.
Preferably, the block rubber that described rubber spring is hollow cylinder, is provided with a dowel screw that coupling shaft and top connection are linked together in the hollow centre of rubber spring.
Preferably, two described guide poles are through sidewall and the top connection clearance fit of rubber spring, and tolerance on fit is H7/g6.
Preferably, two described guide poles are symmetrical about the central axis of rubber spring.
Preferably, lower sub be fixed with a flange seat below by pin, described flange seat is fixed by screws on the worktable of testing machine.
Beneficial effect of the present invention: effectively completed in GB/T3250-2007 about the pilot project requiring in rivet line and rivet shear test, the problem that has needed people's crawl service test machine slowly to reset after at every turn having tested before solving, avoid rigidity contact, eliminated the hidden danger of bad sensor of top.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described further and restriction.
As illustrated in fig. 1 and 2, a kind of shear test automatic reset device, auto-reset function while being mainly used in aluminium and aluminium alloy rivet line shear test, application apparatus is microcomputer controlled electro minor universal testing machine.This shear test automatic reset device comprises from top to bottom the coupling shaft 1, rubber spring 2, the top connection 3 that connect successively, shear attach 4, lower sub 5 and flange seat 10, shearing attaches 4 and comprises that cutter 41 and two are positioned at the side plate 42 of cutter 41 both sides, described cutter 41 links together with top connection 3 by upper latch 7, side plate 42 by lower latch 8 with under connect 5 and link together, lower sub 5 links together by pin 9 and flange seat 10, and flange seat 10 is fixed by screws on the worktable of testing machine.
The inside of described rubber spring 2 is provided with two guide poles 6 that are used for adjusting cutter 41 and side plate 42 right alignmenies about its central axis symmetry, and guide pole 6 is through sidewall and top connection 3 clearance fit of rubber spring 2, and tolerance on fit is H7/g6.When testing machine is attached 4 pairs of samples and carried out the application of force by shearing, the right alignment of cutter 41 and side plate 42 is no more than 10%.
In the present embodiment, described rubber spring 2 is block rubbers of hollow cylinder, that rubber spring has advantages of is more durable than wire spring, be out of shape little, good looking appearance, is provided with a dowel screw that coupling shaft 1 and top connection 3 are linked together in the hollow centre of rubber spring 2.
In order to increase the rigidity of this shear test automatic reset device, the described part except rubber spring has all passed through modifier treatment.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
