Abstract
The utility model provides a matching device of reading microscope for Brinell hardness testing, characterized in that the utility model is arranged on the existing reading microscope, and the Brinell hardness value of tested material can be directly displayed. The device mainly comprises a reading drum, a micrometric screw, two two-stage change gear series, two axes and a strip of paper tape. On the paper tape, the data of the Brinell hardness value is printed. And the data of the Brinell hardness value is displayed via a transparent window on a casing. The device has the advantages of compact structure, high transmission precision and small size, being conveniently arranged on the existing reading microscope. The device also has the advantages that cockamamie process of checking table in the current Brinell hardness testing is eliminated.
Description
The utility model relates to a kind of corollary apparatus that is used for the reading microscope of Brinell test, particularly this device is installed on the existing reading microscope, can directly show the ball hardness number that is verified material.
At present in Brinell test, wish to get out the ball hardness number that is verified material, must be verified the circular impression diameter that material surface is extruded by sclerometer with the reading microscope measurement, again according to the numerical value of survey diameter, consult " Brinell hardness and the impression diameter table of comparisons ", find the ball hardness number that is verified material.Show more than 900 of Brinell hardness Value Datas in the table altogether, when tabling look-up, both made mistakes easily, and efficient is very low.And existing reading microscope does not possess the function of direct demonstration ball hardness number, and therefore tabling look-up becomes loaded down with trivial details and indispensable work in the Brinell test, and work is made troubles to whole test.
The purpose of this utility model is that a kind of direct demonstration ball hardness number device will be provided, and it is installed on the existing reading microscope, does not need to table look-up, and can directly obtain and the corresponding ball hardness number of microscope institute pressure measurement trace diameters.
Utility model is achieved in that a reading drum in the device, have scale to represent measured impression diameter numerical value on the drum, and drum and a micrometric screw connect as one.Also have two axles in the device, the axis of diaxon all with the parallel axes of micrometric screw, continuous between the diaxon, and the pulling force of dependence paper tape is done equidirectional, synchronous rotation by a paper tape.Be printed on whole hardness number data listed in " Brinell hardness and the impression diameter table of comparisons " on the paper tape.The top of paper tape and end are bonded in respectively on two axles, and remainder closely is around on the diaxon respectively.When rotating the reading drum, the micrometric screw that connects as one with drum rotates thereupon, and micrometric screw rotates by the axle that a two stage speed change gear train drives in above-mentioned two axles.At this moment, the paper tape that is positioned at two between centers is in tensioned state and moves up, and drives another root axle simultaneously and does equidirectional, synchronous rotation.When the reading drum stops operating, when its scale indicated institute's pressure measurement trace diameters, paper tape is stop motion also, be positioned at demonstrate on the paper tape of two between centers with the corresponding ball hardness number of the diameters of surveying.To each indicated measurement numerical value of reading drum scale, all there is corresponding with it hardness number to show synchronously on the paper tape, so reach the purpose of direct demonstration ball hardness number.The utility model adopts gear drive, compact conformation, and the transmission accuracy height, volume is little, can be directly installed on the existing reading microscope, and is easy to use.
Introduce the structure and the working condition of utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model fragmentary sectional elevation view.
Fig. 2 is that Fig. 1 is along A-A line cut-open view.
With reference to accompanying drawing, this crust of the device ［ 2 ］ is fixed on the reading microscope main body ［ 1 ］ with screw, and shell ［ 2 ］ can be made of aluminium alloy or engineering plastics.Shell ［ 2 ］ one sides have reading drum ［ 7 ］, and reading drum ［ 7 ］ and micrometric screw ［ 16 ］ are through being threaded.Micrometric screw ［ 16 ］ other end contacts with graticule ［ 20 ］ in the microscope.When rotating reading drum ［ 7 ］, micrometric screw ［ 16 ］ rotates thereupon and drives graticule ［ 20 ］ and moves, and carries out impression diameter and measures.Nut ［ 17 ］ and nut ［ 19 ］ are anchored on gear ［ 18 ］ on the micrometric screw ［ 16 ］.Gear ［ 18 ］, gear ［ 15 ］, gear ［ 14 ］ and gear ［ 10 ］ are formed a two stage speed change gear train, and its middle gear ［ 10 ］ is fixed on the axle ［ 11 ］.When being driving wheel with gear ［ 18 ］, this is taken turns is secondary speedup train, and it mainly acts on is the velocity of rotation that the reading drum ［ 7 ］ and the synchronous rotation of micrometric screw ［ 16 ］ is passed to axle ［ 11 ］ and increase axle ［ 11 ］.On axle ［ 11 ］ and spool ［ 3 ］ closely around paper tape ［ 12 ］, the long 1.3m of paper tape ［ 12 ］, wide 35mm is printed on 924 of Brinell hardness Value Datas regularly on it.Paper tape ［ 12 ］ top is bonding with axle ［ 11 ］, and is terminal bonding with axle ［ 3 ］.Axle ［ 11 ］ and axle ［ 3 ］ material aluminium alloy.Paper tape ［ 12 ］ material is computer printout paper or the high paper of other tensile strength.When counterclockwise rotating reading drum ［ 7 ］, micrometric screw ［ 16 ］ rotates thereupon and rotates to counter clockwise direction by secondary speedup train driving shaft ［ 11 ］.The paper tape that is around on the axle ［ 11 ］ is done synchronous, equidirectional rotation with axle rotation and drive axle ［ 3 ］.At this moment, the paper tape that is positioned at two between centers is in tensioned state and moves up.Scale on reading drum ［ 7 ］ rotates lattice (the wide 1mm of lattice), paper tape ［ 12 ］ lattice (the wide 4mm of lattice that just moves up, this is the expansion effect that the speedup train produces), be printed on the impression diameter numerical value corresponding ball hardness number represented in the lattice with reading drum ［ 7 ］ high scale.Hardness number shows by the last transparent organic glass window ［ 13 ］ of crust of the device ［ 2 ］.Each measurement numerical value represented to reading drum ［ 7 ］ high scale, window ［ 13 ］ all has corresponding with it ball hardness number to show synchronously.One handwheel ［ 6 ］ is arranged on this crust of the device ［ 2 ］, fixing gear ［ 5 ］ on the axle of handwheel ［ 6 ］.Gear ［ 5 ］, gear ［ 8 ］, gear ［ 9 ］ and gear ［ 4 ］ are formed a two stage speed change gear train.Gear ［ 4 ］ is fixed on the axle ［ 3 ］.When the effect of handwheel ［ 6 ］ is to make its clockwise direction to rotate, can rotation be passed to reading drum ［ 7 ］ by the gear train in the device, thereby the clockwise direction that realizes reading drum ［ 7 ］ is rotated.All modules are 0.5 in this device, and material is with 45 steel or aldubra.
