Description
Technical field
The utility model relates to a kind of lighting device for Brinell tester reading microscope, belongs to measurement survey field.
Background technology
Brinell hardness is conventional Hardness Surveillance method, its principle is hardened steel ball or the sintered carbide ball of D with diameter, with corresponding test force F pressing in sample surface, removal test force after maintenance official hour, spherical indentation is left at specimen surface, use Brinell tester reading microscope to measure, from the Brinell hardness table got ready, find ball hardness number according to impression diameter.Because impression diameter is only 2 ~ 5mm, reading microscope must be used to carry out observation measure, be accurate to 0.01mm, therefore want Measurement accuracy impression diameter, reading microscope is most important, common reading microscope does not throw light on, and must have good daylighting or by the external light source such as torch, desk lamp during use, but actual when using, residing environment daylighting is bad, or there is no other external light sources, will the measurement accuracy of impression diameter be had a strong impact on, and even cannot see impression clearly.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of structure simple, easy to use for the microscopical lighting device of Brinell tester, overcome microscope reading conditions light difference, affect the defect of daylighting and reading effect.
The utility model solves the technical scheme that its technical matters adopts: a kind of Brinell tester reading microscope lighting device, and it comprises fixed arch plate, is arranged on the lamp group of fixed arch plate, the gauge tap that is connected successively by circuit with described lamp group and supply unit; The internal diameter of described fixed arch plate mates with the external diameter of Brinell tester reading microscope lens barrel and arranges.
Further improvement, the radian of described fixed arch plate is 200 ° ~ 270 °.
Further improvement, described fixed arch plate is rigid plastic or metal material.
Further improvement, described lamp group is embedded in the inner side of fixed arch plate.
Described fixed arch plate and the long lens barrel of Brinell tester reading microscope are interference fit.
The inner side of described fixed arch plate refers to and the side that microscope lens barrel is fitted.
The beneficial effect of utility model is as follows:
1. the utility model has set up lighting device, for reading microscope provides reliable light source, guarantees the accuracy that impression diameter is measured;
2. the internal diameter of fixed arch plate of the present utility model mates with the external diameter of Brinell tester reading microscope lens barrel and arranges, the radian of fixed arch plate is 200 ° ~ 270 °, be interference fit with Brinell tester reading microscope lens barrel, guarantee that shell can be stuck in outside the daylight opening of common reading microscope;
3. lamp group is arranged on inside fixed arch plate by the utility model, concentrates on inside microscope, more know reading by reliable light source.

Embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described further.
See accompanying drawing 1-3, the present embodiment comprises fixed arch plate 1, be arranged on lamp group 2 on fixed arch plate 1 and the gauge tap 3 that is connected successively by circuit with lamp group and supply unit 4; The internal diameter of described fixed arch plate 1 mates with the external diameter of the long lens barrel 5 of Brinell tester reading microscope and arranges, and the radian of described fixed arch plate 1 is 200 ° ~ 270 °; Described fixed arch plate 1 is rigid plastic or metal material.Described fixed arch plate and the long lens barrel of Brinell tester reading microscope are interference fit; The inner side of described fixed arch plate refers to and the side that microscope lens barrel is fitted; Described lamp group 2 is arranged on the inner side of fixed arch plate 1.
Described fixed arch plate 1 is interference fit with Brinell tester reading microscope lens barrel, fixed arch plate 1 adopts rigid plastic or metal to make, there is certain toughness and hardness, shell radian is between 200 ° ~ 270 °, internal diameter of outer cover is consistent with common reading microscope external diameter, 34mm, adopts interference fit, guarantees that shell can be stuck in outside the daylight opening of common reading microscope.
Described lamp group 2 is embedded in the inner side of fixed arch plate 1, and is built in the plane inside fixed arch plate 1.
The center line of described lamp group 2 inside the fixed arch plate 1 and axial direction along fixed arch plate 1 arranges one group, also can according to light need to arrange two groups and more than.
As illustrated in figures 4-5, the structure of Brinell tester reading microscope comprises long lens barrel 5, objective tube 6, lens barrel base 7, lock screw 8, eyepiece 9 and reading drum 10.During use, be interference fit by fixed arch plate 1 with the long lens barrel of Brinell tester reading microscope, fixed arch plate 1 is enclosed within long lens barrel 5, surround and shelter from objective tube 6, when measuring, first open gauge tap 3, make supply unit 4 provide reliable light source for reading microscope, guarantee the accuracy that impression diameter is measured.
