Description
Technical field
This utility model belongs to technical field of measurement and test, especially relates to multidiameter sample, assembly sample hardness test clamping device with cylinder.
Background technology
Hardness is to weigh performance indications of material soft or hard degree, and hardness test is as the Physico-chemical tests means of a kind of routine, essential during failure analysis and quality inspection.The test button surface smoothness to be measured of hardness test requires higher, and the most guaranteed penetrator is vertical with specimen surface, and test data are only really, just have credibility.Assembly sample for multidiameter sample, with cylinder carries out hardness measurement at present, the end face of small column or the end face of assembly cylinder are supporting surface, need to measure the hardness of another one end face, and the area of supporting surface is less than the area of end face to be measured, when so carrying out hardness measurement, the measurable range of tested surface is less or support shaft is unstable, causes measurement result inaccurate.It is the problem measuring big measured surface hardness under small column supporting surface to this end, to be solved in the utility model.
Summary of the invention
The purpose of this utility model provides a kind of for clamping multidiameter sample, assembly sample hardness test clamping device with cylinder.
The technical scheme realizing this utility model purpose is: a kind of novel hardness test clamping device, including pedestal, guide rail, little leading screw, handle, bracer, slide block, support platform, bearing pin, big leading screw, round platform.Pedestal is a tetragonal body with protruding round platform, and before and after tetragonal body upper surface, both sides have closed slide, and the left and right sides has two protruding bracers；Having major thread hole in round platform, major thread hole coordinates with the big leading screw with cylindrical support platform, has pin-and-hole in the sagittal plane of support platform, and bearing pin is arranged in pin-and-hole, and rotating pin makes big leading screw move up and down, thus regulates the height of support platform；Propping up and have minor thread hole on bracer, minor thread hole coordinates with the little leading screw with handle, and the other end of little leading screw is connected with the slide block with arc-shaped curved surface, and turning handle makes little leading screw band movable slider move on guide rail.
The arc-shaped curved surface radius of slide block is more than the radius of round platform.
The screw thread pair that the screw thread pair that big leading screw is formed with the screwed hole on round platform, little leading screw are formed with the screwed hole on a bracer has self-locking property, prevents from threaded automatically getting loose.
The beneficial effects of the utility model are:
(1) in this utility model, support platform provides bottom support to sample, and the height of support platform can regulate, and thus expands the test scope of hardness testing device；
(2) slide block can move on guide rail, moving range according to the size adjustment slide block supporting cylindrical radius, inside slide block, support cylinder is played the effect of clamping by arc-shaped curved surface, the upper surface of slide block is played a supporting role, the most both improve the test specimen stability when hardness test, expand again the test scope of hardness testing device；
(3) this harness can be directly placed on the test platform of hardness testing device use, only needs mobile foundation, it is not necessary to repeatedly load and unload sample in test process, saves the testing time.
