Description
Technical field
This utility model relates to a kind of self-retaining formula optical measurement microscope.
Background technology
Portable optical measuring microscope due to simple in construction, easy to operate, is widely used in every profession and trade equipment, parts
Online quality control.On-line determination pitch-row, impression especially for hardware parts especially ferrimagnet metal parts
The application such as size, groove size, width of keyway, surface quality, powder particle size, coating layer thickness is universal.
The field number of portable optical measuring microscope is about about 10mm, measures scope and certainty of measurement according to amplification
Multiple is different and different, and amplification is big, scope is big, precision is high in measurement, as amplification 40 ×, measurement scope is generally 4mm,
Precision 0.005mm.Owing to being portable optical measuring instrument, during on-line measurement, with a hands, microscope must be fixed on metal work
On part, and another hands is carried out focusing, rotating microdrum, carries out observing, reading etc. simultaneously, need in using right-hand man, eye with
Step cooperation, operation easier is big, is difficult to avoid that in operation because arm rocks, grasps tight and site environment interference etc. and make simultaneously
The bigger measurement error that the instrument become produces relative to the micro-displacement of workpiece.For the workpiece that on-line measurement precision is higher,
As for Bush, the impression dimensional measurement of Rockwell hardness test, this portable micro-bigger error that exists in actual use, need
Repetitive measurement is averaged, and adds the measurement workload of testing staff.
Summary of the invention
The purpose of this utility model is to provide a kind of self-retaining formula optical measurement microscope, by setting at Microscope base
Put permanent magnetism seat cushion, by magnetic material, microscope can be fixed on testee, facilitate operation.
The purpose of this utility model is achieved through the following technical solutions, a kind of self-retaining formula optical measurement microscope,
Including microscope body, microscope body has lens barrel, lens barrel lower end to be lens barrel base, and wherein, described lens barrel base passes through one
Permanent magnet material base is fixed on metal works, is provided with NULL, lens barrel between described lens barrel base and permanent magnet material seat
Base is fixing with NULL to be connected.
Scheme is further: described permanent magnet material base is an annular permanent-magnet material base being nested with lens barrel base,
A Magnetic isolation set made of copper, the upper end side of described Magnetic isolation set it is provided with between annular permanent-magnet material base and lens barrel base
Outwards putting on display and cover annular permanent-magnet material upper surface, lens barrel base is screwed with Magnetic isolation set and is connected.
Scheme is further: described Magnetic isolation made of copper set and described annular permanent-magnet material base are to be linked as one by bonding
The structure of body.
Scheme is further: described permanent magnet material base is Nd-Fe-B permanent magnet material base, and, permanent magnet material base
Magnetic attraction is greater than microscope weight.
Scheme is further: described permanent magnet material base is a rectangle or cylindrical base.
Scheme is further: described lens barrel is that nonferromugnetic material makes.
The utility model has the advantage of:
1) this utility model uses the lens barrel base of permanent magnet material, makes described microscope be fixed on ferromagnetic workpiece voluntarily
On.During on-line measurement, it is to avoid instrument displacement that during measuring, anthropic factor causes and the measurement error that produces, vacate simultaneously
One hands, reduces the measurement difficulty of operator, is effectively increased certainty of measurement and work efficiency.
2) this utility model lens barrel uses nonferromugnetic material, it is to avoid after directly contacting with the lens barrel base of permanent magnet material
It is magnetized, so that adsorbing ferromagnetic molecule in Shi Yonging and affecting Optics in Microscope and measure the normal use of parts.
Below in conjunction with the accompanying drawings and this utility model is described in further detail by detailed description of the invention.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
A kind of self-retaining formula optical measurement microscope, as described in Figure 1, including microscope body, microscope body includes:
Eyepiece 1, micrometering adjustment drum 2, lock screw 3, object lens 4, the connection of lens barrel 5 lower end have lens barrel base 6；Wherein, at the bottom of described lens barrel
Seat is fixed on metal works by a permanent magnet material base 7, be provided with between described lens barrel base and permanent magnet material seat every
Magnetic material sleeve 8, lens barrel base is connected by screw 9 is fixing with NULL set, and in order to avoid magnetization, described lens barrel is non-ferromagnetic
Property material make, such as make of bakelite.
In embodiment: described permanent magnet material base is an annular permanent-magnet material base being nested with lens barrel base, at ring
A Magnetic isolation set made of copper it is provided with, outside the upper lateral of described Magnetic isolation set between shape permanent magnet material base and lens barrel base
The plane 801 put on display covers annular permanent-magnet material upper surface so that during work, permanent magnet material base will not magnetize tested portion
Part, lens barrel base is screwed with Magnetic isolation set and is connected, and the connection of this mode avoids permanent magnet material base by fixing
Screw magnetization lens barrel base.
In embodiment: described Magnetic isolation made of copper set and described annular permanent-magnet material base are by the bonding company of the quick-fried technology of copper
The structure being integrated.
In embodiment: described permanent magnet material base is Nd-Fe-B permanent magnet material base, and Nd-Fe-B permanent magnet material has magnetic
Ferromagnetism keeps long feature, and, the magnetic attraction of permanent magnet material base is greater than microscope weight.
In embodiment: described permanent magnet material base is a rectangle or cylindrical base.
Confirm before using that lens barrel base is connected firmly with permanent magnet material base, if any getting loose, twist symmetry point by screwdriver
The tight screw hole internal thread of cloth.Measured workpiece surface appearance is first observed, by be measured for lens barrel centre hole of base alignment during use
Hole, indentation or impression, hold lens barrel permanent magnet material base and first contact workpiece, feels when having suction, by permanent magnet material base
Setting level, lens barrel breach direction is towards radiation direction, it is to avoid lead because suction is excessive when being directly placed on workpiece by permanent magnet material base
The microscope components caused is damaged；Focusing makes measured blur-free imaging with on eyepiece, rotates microdrum and reads measurement data also
Record, holds after permanent magnet material base is first left workpiece by lens barrel and is taken away from surface of the work by microscope, clear after having detected
The ferromagnetic particle of reason lens barrel base absorption.
