Abstract
A kind of portable metallographic specimen sander, including pedestal, planetary gear, planet carrier, sun gear, support, shaft, bracket, crank, counterweight, servo, limit sample circle；Planet carrier and sun gear are by the way that on bearing erection support, planetary gear, planet carrier, sun gear and pedestal constitute planetary gear rotation system together；The bottom surface of support and the bottom surface of pedestal are in same level；Bracket is mounted on pedestal, and crank or servo are mounted on bracket and are connect by shaft with sun gear.The utility model is portable, convenient and flexible operation, at low cost, is able to satisfy the requirement that school instruction and researcher polish to metallographic；There is curved surface and the problem of a large amount of deep scratches occur in discontinuity, surface when can effectively improve hand sand metallographic test, reduce the labor intensity of student or researcher etc., improve the efficiency of metallographic polishing.
Description
Technical field
The utility model belongs to field of material preparation, is related to a kind of laboratory metallographic specimen grinding apparatus.
Background technique
To observe metallographic microstructure, generally sample is cut, inlays and is prepared into metallographic specimen, then to surface into
Row grinding process.Laboratory mainly uses two methods to metallographic specimen polishing at present, and one kind is to carry out beating by hand using sand paper
Mill, since sample is smaller and irregular, the manual grinding time is longer and sample does not have limiting device, finger acid is easy to cause to tire out,
There is multiple planes or curved surface and there is the problems such as many deeper scratches in specimen surface, this and be unfavorable for the sight of microscopic structure
It examines；For another kind to be polished using desk-top metallographic sander, this grinding apparatus is relatively large and costly, cannot arbitrarily move flexibly
It uses, and the more wasteful energy.Therefore, the metallographic specimen sander for designing miniature portable can improve metallographic preparation quality
And efficiency, reduce the labour of student and researcher etc..
Utility model content
In view of the above-mentioned problems, providing a kind of cellular-type metallographic specimen sander, it overcomes beats the utility model by hand
The disadvantages of metallographic tries discontinuity low efficiency, surface quality is poor is ground, the utility model not only realizes different sizes and shapes
The polishing of metallographic specimen, and realize hand sand or automatically grinding function.
The utility model is achieved through the following technical solutions.
A kind of portable metallographic specimen sander described in the utility model, including pedestal, planetary gear, planet carrier, the sun
Wheel, support, shaft, bracket, crank, counterweight, servo, limit sample circle.
Planet carrier and sun gear are by the way that on bearing erection support, planetary gear, planet carrier, sun gear and pedestal constitute row together
Star-wheel rotation system；The bottom surface of support and the bottom surface of pedestal are in same level.
Bracket is mounted on pedestal, and crank or servo are mounted on bracket and are connect by shaft with sun gear,
Driving force is provided for planet gear transmission system.
There are four planetary gears, all mountable sample of each planetary gear.Planetary gear can install different sizes and shapes
Sample circle is limited, is polished with realizing the metallographic specimen of different size and specification.
Metallographic specimen described in the utility model is mounted in planetary gear, and will be golden by the counterweight of different weight or quantity
Phase sample compresses, and makes metallographic specimen uniform stressed.
Connection type convenient for loading and unloading is used between crank and servo and bracket described in the utility model；Described watches
Take the big torque servo machine that machine is miniature adjustable speed.
Compared with existing metallographic grinding apparatus, the distinguishing feature of the utility model is portable, and convenient and flexible operation is at low cost,
It is able to satisfy the requirement that school instruction and researcher polish to metallographic.When the utility model can effectively improve hand sand metallographic test
There is curved surface and the problem of a large amount of deep scratches occur in discontinuity, surface, and the labour for reducing student or researcher etc. is strong
Degree improves the efficiency of metallographic polishing.
Detailed description of the invention
Fig. 1 is the axis side view of the utility model.
Fig. 2 is the axis side view of the utility model.
Fig. 3 is the bottom view of the utility model.
Fig. 4 is the left view of the utility model.
Fig. 5 is the round limit sample circle of the utility model.
In figure: 1 pedestal, 2 planetary gears, 3 planet carriers, 4 sun gears, 5 supports, 6 shafts, 7 brackets, 8 cranks, 9 counterweights, 10 watch
Take machine, 11 limit sample circles.
Specific embodiment
To make the purpose of this utility model, technical solution and advantage become to be best understood from, below in conjunction with attached drawing, to this
Utility model is described in detail.It should be appreciated that the specific embodiments described herein are used merely to explain the utility model,
It is not used to limit the utility model.
Referring to attached FIG. 1 to FIG. 5, a kind of portable metallographic specimen sander described in the present embodiment, including pedestal 1, planet
Wheel 2, planet carrier 3, sun gear 4, support 5, shaft 6, bracket 7, crank 8, counterweight 9, servo 10, limit sample circle 11.3 He of planet carrier
Sun gear 4 is by the way that on bearing erection support 5, planetary gear 2, planet carrier 3, sun gear 4 and pedestal 1 constitute planetary gear rotation system together
System；The bottom surface of support 5 and the bottom surface of pedestal 1 are in same level.Bracket 7 is mounted on pedestal 1, crank 8 or servo
Machine 10, which is mounted on bracket 7, to be connect by shaft 6 with sun gear 4, provides driving force for planet gear transmission system.Planetary gear 2 has four
It is a, all mountable sample of each planetary gear.Planetary gear 2 can install the limit sample circle 11 of different sizes and shapes, with realization pair
The metallographic specimen of different size and specification is polished.
Power is provided for planet gear transmission system by shaft 6 in 10 mounting bracket 7 of crank 8 or servo, so that planetary gear 2
Rotation and revolve around sun gear, crank 8 and servo 10 can arbitrarily be replaced according to the requirement of user with realize manually or
Automatically grinding metallographic specimen.
In use, abrasive paper for metallograph or silicon carbide paper are entirely placed on sample preparation table, then by metallographic specimen sander
It is placed on abrasive paper for metallograph, the movement of sand paper is avoided under the gravity of pedestal.By the sample inlayed or cutting
Good sample selects suitable limit sample circle, is installed on planetary gear, then places counterweight and compress sample, and each planetary gear can all pacify
Fill a sample.
Then, crank or servo are installed, sun gear and planetary gear are uniformly driven, thus realize metallographic specimen rotation and
Around the effect of sun gear revolution, and then realize specimen surface uniform grinding.
The above is only the preferred embodiment of the utility model, it is noted that for the skill of the art
For art personnel, without departing from the principle of this utility model, several improvement can be carried out, these improvement also should be regarded as this
The protection scope of utility model.
