Abstract
Disclosed is a sample scale distance dotting device for mechanical tension test. The device is formed by connecting and combining an upper box-type support shell and a lower box-type support shell equal in size through screws penetrating left lugs and right lugs and nuts, and the spatial distance of the upper and lower support shells is changed by simultaneously adjusting the heights of the nuts. The upper support shell specifically comprises two horizontal roller beds and a horizontal shaft, two ends of each horizontal roller bed are supported by bearings, the horizontal roller beds are respectively mounted at the left end and the right end of the upper support shell, and the horizontal shaft with both ends supported via bearings and provided with shakable handles can be used for vertically mounting a dotting gear piece. The lower support shell specifically comprises three horizontal roller beds, two ends of each horizontal roller bed are supported by bearings, one horizontal roller bed is mounted under the dotting gear piece, and the other two roller beds are mounted at the positions under the roller beds of the upper support shell. A continuous dotted line at 10-mm intervals can be formed on a sample dotting surface, and the diameter and the depth of dotting are both less than 1mm. The sample scale distance dotting device for mechanical tension test has the advantages of precision manufacturing, no longest scale distance limitation, portability, small occupied area, low manufacturing cost and the like.
Description
Technical field
Belong to field of material engineering technology, relate to mechanical stretch experimental sample mark square device for dotting.
Background technology
In the research and production detection fields such as material, machinery, building, mechanical property stretching experiment has become the basic means of the tensile property that detects analysis of material.Mark square device for dotting is to mark for test material percentage elongation the device that square is got ready.At present, there is DX300 tensile test specimen scale distance instrument dotting machine in market, the longest gauge length 300mm, and fixing 10mm spacing, row's formula is got gauge length ready, and efficiency is high.This equipment is the axle rotating 360 degrees that has a hurricane band by, lifts drift in different angles order, and impacts and get ready by the elastic force order of spring.Handle shakes, and within one week, can in sample blanks, to get spacing arranged in a straight line be the 10mm accurate sample of totally 31 points (overall length 10mmX (31-1)=300mm).For another example LB-40 continous way reinforcing bar dotting machine, can be used for round steel, band steel, steel pipe, shaped steel and other nonferrous materials mark point marks, for sample stretching.This device structure is accurate, and easy to use, efficiency is high, gets ready accurately, is also convenient to check and repair.The technical requirement of continous way reinforcing bar dotting machine, every shake once, can break into 40 punctuates.The distance of punctuate is 10mm, be no more than ± 0.15mm of error, the about 400mm of total length gauge length.In fact, above-mentioned dotting machine all exists and gets quantity ready and the shortcoming such as length distance is limited.The utility model discloses one for mechanical stretch experimental sample mark square device for dotting, can make up the deficiency of the said goods.
Summary of the invention
The purpose of this utility model be to provide a kind of easy to operate, durable in use, precision and efficiency high for mechanical stretch experimental sample mark square device for dotting.
The utility model is achieved in that device runs through left and right ear by upper and lower two box support housings of equidimension by screw and nut and is connected and combines, and can change the space length of upper lower support by while adjusting nut height.Upper supporter specifically comprises that there are two of the horizontal rollers of bearings at two ends, are arranged on respectively two ends, supporter left and right; There is one of bearings and the trunnion axis of can at right angle setting getting gear sheet ready that can swinging handle at two ends.Lower support specifically comprises that there are three of the horizontal rollers of bearings at two ends, occurs bending and deformation when not making sample get ready, one of horizontal roller is installed under the trunnion axis of getting gear sheet ready is installed.All the other two are arranged on respectively position under supporter roller-way.
When use, first the type nut that emits of two vertical roller-way upper ends is pulled to device edge direction level, the spring that supports vertical roller is compacted, make sample material can put between the vertical roller-way of upper and lower two pairs of horizontal rollers and two pairs of front and back and contact with roller-way, the nut of Manual tightening device left and right ear, makes two pairs of roller-ways of lath sample and upper and lower front and back contact compression.Agitating device one side and the handle of getting gear ready and being connected, get gear ready and rotate thereupon, and teeth start to get ready in a plane of sample, and teeth number is 5～20.Use continuously hand fixed handle, sample to get the upper continuous dotted line forming taking 10mm as interval in surface ready, get diameter and the degree of depth ready and be all no more than 1mm.The utlity model has and manufacture accurately, without the longest mark square restriction, be easy to carry, the feature such as floor space is little, low cost of manufacture.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is further described.
Embodiment 1:
Utility model device runs through left and right ear by upper and lower two box support housings of equidimension by screw and nut and is connected and combines, and can change the space length of upper lower support by while adjusting nut height.Upper supporter specifically comprises that there are two of the horizontal rollers of bearings at two ends, are arranged on respectively two ends, supporter left and right; There is one of bearings and the trunnion axis of can at right angle setting getting gear sheet ready that can swinging handle at two ends.Lower support specifically comprises that there are three of the horizontal rollers of bearings at two ends, one of horizontal roller is installed under the trunnion axis of getting gear sheet ready is installed, and all the other two are arranged on respectively position under supporter roller-way.When use, first the type nut that emits of two vertical roller-way upper ends is pulled to device edge direction level, the spring that supports vertical roller is compacted, make sample material can put between the vertical roller-way of upper and lower two pairs of horizontal rollers and two pairs of front and back and contact with roller-way, the nut of Manual tightening device left and right ear, makes two pairs of roller-ways of lath sample and upper and lower front and back contact compression.Agitating device one side and the handle of getting gear ready and being connected, get gear ready and rotate thereupon, and teeth start to get ready in a plane of sample, and teeth number is 16.Use continuously hand fixed handle, sample to get the upper continuous dotted line forming taking 10mm as interval in surface ready, get diameter and degree of depth 0.9mm ready.
