Abstract
Steel wire Young's modules instrument levelling device of the present invention mainly includes upper measuring table, lower measuring table, platform connecting spring, lower collet, levelling bolt, air level.When experiment, lower collet passes through the center circular hole of upper measuring table and lower measuring table, three grooves for adjusting lower collet are concordant with the bottom surface of upper measuring table, the upper bottom surface of lower measuring table, the bottom surface of lower measuring table respectively, ensure that lower collet is concordant with measuring table as reference；Air level is placed on upper measuring table, turns three levelling bolts repeatedly until air level display level, removes air level, beginning measurement experiment data.Measuring table can be made horizontal by above adjusting and can guarantee that lower collet is concordant with measuring table, and then guarantee the establishment of steel wire Young's modulus measurement formula.
Description
Technical field
The present invention is used for steel wire Young's modules instrument measuring steel wire diameter field.
Background technique
The Young's modulus that pulling method measures steel wire is a traditional Physical Experiment, in the adjusting and use of instrument and reality
Testing data processing etc. has important role to the experimental skill of training student.In an experiment, steel wire Young's modulus measures
The condition that formula is set up is: the brachium that steel wire is elongated forward and backward optical lever forms a right angled triangle on the vertical plane, that is, requires
Measuring table is horizontal and collet is concordant with measuring table, and current laboratory apparatus does not ensure that the level of measuring table,
And it is also by feel that there is no a measurement standards, can thus introduce and compare that adjusting collet is concordant with measuring table
Big error.
Summary of the invention
In order to overcome the measuring table in laboratory apparatus unhorizontal and collet and these not concordant disadvantages of measuring table, this
Invention devises steel wire Young's modules instrument levelling device, can be very good to solve these problems.
Steel wire Young's modules instrument levelling device of the present invention mainly include upper measuring table, lower measuring table,
Platform connecting spring, lower collet, levelling bolt, air level.It is the circular hole of 2.5cm that, which there is a diameter at the center of upper measuring table,
It is the circular hole of 2.5cm, upper measuring table, lower measurement that lower measuring table also has a diameter as upper measuring table at center
The thickness of platform is 1cm, lower measuring table there are three diameter be 0.8cm threaded hole, platform connecting spring be one from
The compressed spring that right length is 1cm, lower collet are that a diameter is 2.4cm, are highly the cylindrical body of 6cm, from the top of lower collet
End starts just to engrave groove at the one of cylinder week every 1cm, levelling bolt is that diameter is 0.8cm, and length is until at 3cm
The screw of 2.5cm, makes three levelling bolts, and three levelling bolts pass through three spiral shells that diameter in lower measuring table is 0.8cm
Pit, just with the bottom face contact of upper measuring table, air level is the round water that a diameter is 3cm on the top of levelling bolt
Quasi- bubble.When experiment, lower collet passes through the center circular hole of upper measuring table and lower measuring table, adjusts three of lower collet
Groove is concordant with the bottom surface of upper measuring table, the upper bottom surface of lower measuring table, the bottom surface of lower measuring table respectively, as
Reference ensures that lower collet is concordant with measuring table；Air level is placed on upper measuring table, turns three tune repeatedly
Plain screw removes air level, starts measurement experiment data until air level display level.It can make to measure by above adjusting
It plateau levels and can guarantee that lower collet is concordant with measuring table, and then guarantee the establishment of steel wire Young's modulus measurement formula.
The advantage of the invention is that ensuring that upper measuring table is horizontal by adjusting three levelling bolts, lower folder is adjusted
Three grooves of head are flat with the bottom surface of the bottom surface of upper measuring table, the upper bottom surface of lower measuring table, lower measuring table respectively
Ensure that lower collet is concordant with upper measuring table, together so as to avoid because measuring table is not horizontal and lower collet and measurement
Platform it is not concordant and caused by error.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is lower chuck structure schematic diagram of the invention.
In Fig. 1,1, air level, 2, upper measuring table, 3, lower measuring table, 4, levelling bolt, 5, threaded hole, 6, lower measurement
The center circular hole of platform, 7, platform connecting spring, 8, the center circular hole of upper measuring table, in Fig. 2,9, lower collet, 10, lower folder
Equidistant groove on head.
Specific embodiment
In Fig. 1, platform connecting spring (7) is connect respectively with upper measuring table (2), lower measuring table (3) and fixed, tune
Plain screw (4) passes through the threaded hole (5) in lower measuring table, and the top of levelling bolt (4) is just and under upper measuring table (2)
Bottom surface contacts, and the lower collet (9) in Fig. 2 passes through the center circle of the center circular hole (8) of upper measuring table and lower measuring table in Fig. 1
Hole (6), the grooves (10) such as lower collet in Fig. 2 respectively with the bottom surface of the upper measuring table (2) in Fig. 1, lower measuring table (3)
Upper bottom surface it is concordant, when adjusting horizontal, air level (1) is placed on upper measuring table (2), has adjusted level later water
Quasi- bubble (1) is removed.
Claims (1)
1. steel wire Young's modules instrument levelling device, it is characterized in that platform connecting spring (7) respectively with upper measuring table (2),
Lower measuring table (3) connects and fixed, threaded hole (5) of the levelling bolt (4) in lower measuring table, levelling bolt (4)
Bottom face contact of the top just with upper measuring table (2), lower collet (9) pass through the center circular hole (8) of upper measuring table under
The center circular hole (6) of measuring table, the grooves such as lower collet (10) respectively with the bottom surface of upper measuring table (2), lower measuring table
(3) upper bottom surface is concordant, and when adjusting horizontal, air level (1) is placed on upper measuring table (2), after having adjusted level
