Technical field
The utility model relates to the experimental technique field of metal material quasistatic fracture toughness, and particularly a kind of test aid is a specific purpose tool of adjusting three point bending test device right alignment.
Background technology
Stipulate in the uniform tests method standard according to metal material quasistatic fracture toughness that charger should be coaxial, loaded line should equate with the spacing at two backing roll centers, and the difference of distance is less than 1% of two backing roll spacings.The placement location of sample should make crack tip be positioned at two backing rolls center, is accurate to 1%S; Sample should be vertical with backing roll simultaneously, and deviation is in ± 2 °.
But, in test, conveniently install sample, and the requirement that makes it to satisfy the uniform tests method standard is difficult to accomplish.For head it off, innovation and creation be used to adjust the specific purpose tool of right alignment between three point bending test device and the sample in a kind of fracture mechanics test.
The utility model content
The purpose of this utility model is: a kind of instrument that is used to adjust three point bending test device right alignment is provided, can adjust test unit and sample right alignment, and satisfy the requirement of test unit and sample right alignment in the three point bending test, three-point bending sample for different size can both use, and improves test accuracy and test efficiency.Overcome when having test unit installation sample now, be difficult to satisfy the deficiency that the uniform tests method standard requires.
The technical solution adopted in the utility model is: the instrument that is used to adjust three point bending test device right alignment, mainly form by spacer, support, blade, pressure roller and backing roll, it is characterized in that: leading flank and trailing flank at pressure roller have a spacer by screw retention respectively, and spacer is parallel with pressure roller.Be fixed with a support on two spacers respectively, two supports are parallel to each other and are vertical with spacer.Bottom at support has rectangular through-hole respectively.The two ends of blade are fixed in the rectangular through-hole of two supports.Blade is a cuboid, and length is 80 millimeters, and thickness is 1 millimeter, and blade has the blade and the knife back, at the two ends of the knife back installation gap is arranged respectively, two gap is installed and is symmetrically distributed.Backing roll is a cuboid, and two contour strip bulges are arranged on last plane, and the top of strip bulge is an arc surface.Backing roll is the supporting sample and bears test pressure.
Described blade two ends are fixed in the rectangular through-hole of support, are to adopt interference fit to fix.
The width that gap is installed at described knife back two ends is 2 millimeters.
Installation gap on the described blade knife back adopts line to be cut into.
At present regulation three-point bending sample break has four kinds of forms, is respectively chevron breach, through-type breach, terminally is the circular breach and the breach of molybdenum filament.The utility model blade can be applicable to the sample of these four kinds of breach forms.
The beneficial effects of the utility model: the utility model is used to adjust the instrument of three point bending test device right alignment, for the three-point bending sample of different size, different breach forms all with this device right alignment, the location accurately, can satisfy in the standard requirement to right alignment between pressure roller, sample and the backing roll, improve test accuracy and test efficiency, and installation, dismounting, easy to use, practical.
