Abstract

The utility model discloses a grinding and polishing device for a transmission electron microscope film sample. The grinding and polishing device for the transmission electron microscope film sample is characterized in that four through holes are formed in a cylindrical base body. Apart from the center through hole, the rest three through holes are evenly distributed around the center of the bottom of the cylindrical base body and matched with three cylindrical support pillars in a sliding mode. A cylindrical sleeve of a rotation screw rod is fixedly connected with the corresponding through holes in the cylindrical base body through screws. A threaded through hole for the screw rod to enter and exit is formed at the center of the cylindrical sleeve. A through hole which corresponds to the through hole at the center of the cylindrical base body is formed in a right-angle prismatic table. A screw bolt penetrates through the center through hole and fixedly connects the center through hole with the cylindrical base body. An edge angle of the right-angle prismatic table is provided with a semi-round groove and a through hole of two thirds of a round. A micrometer head is matched with the right-angle prismatic table, fixed through the semi-round groove and locked with a screw. The grinding and polishing device for the transmission electron microscope film sample is simple in structure, low in manufacturing cost and capable of precisely controlling an angle of inclination of a wedge-shaped sample so as to enhance manufacturing efficiency of samples and improve uniformity of ground samples.

Description

A kind of grinding and polishing device for the transmission electron microscope film sample
Technical field
The utility model relates to a kind of grinding and polishing device for the transmission electron microscope film sample.
Background technology
Desirable transmission electron microscope film sample requires to have area greatly and evenly and unmanned thin (electron beam is transparent) district for defective, preparing such sample will be through the attenuate of multiprogramming, the general first step is the pre-attenuate (grinding) of machinery, just can carry out next step attenuate after requiring to be ground to about 30 μ m at least, therefore mechanical lapping is one of committed step of transmission electron microscope film sample preparation, and good milling tool is also particularly important.
Although the hand lapping device is had relatively high expectations to the operator's, because it more economically, thereby use comparatively extensive.At present, the grinding and polishing device of the transmission electron microscope film sample preparation of selling on the market, or expensive, efficient is lower, or complex structure, operation inconvenience.Wherein, at the grinding of wedge shape sample, most milling tool has adopted a plurality of differential heads to carry out angular adjustment, does not so not only improve efficient and the precision of grinding greatly, has increased the manufacturing cost of instrument on the contrary.And an innovation part of the present utility model just is only to adopt to make that in the guaranteed while of precision the manufacturing cost of device is greatly saved in the angle of inclination of a differential head control wedge shape sample.
The utility model content
The utility model provides a kind of grinding and polishing device that is used for the transmission electron microscope film sample that can significantly save manufacturing cost and improve grinding efficiency at the deficiency of existing hand lapping instrument.
The utility model is achieved through the following technical solutions:
A kind of grinding and polishing device for the transmission electron microscope film sample, this grinding and polishing device comprise cylindrical base, three cylinder pillars, three rotary screws, right angle terrace with edge and differential heads.
Cylindrical base has four through holes, and except central through hole, its excess-three through hole evenly distributes around the center of circle of cylindrical base bottom, and three through holes and three cylinder pillars are slidingly matched.
Rotary screw comprises cylindrical sleeve and screw rod two parts, and cylindrical sleeve is fixedlyed connected with respective through hole on the cylindrical base by screw, and the center of cylindrical sleeve has tapped through hole, for the screw rod turnover.
The through hole corresponding with the through hole at cylindrical base center arranged on the right angle terrace with edge, and bolt passes central through hole fixedlys connected it with cylindrical base; The edges and corners of right angle terrace with edge have semi-circular recesses and 2/3rds manholes.
The differential head cooperates with the right angle terrace with edge, fixes by semi-circular recesses, and utilizes screw lock.
The utlity model has simple in structurely, cost is low, can carry out advantages such as micron level ground grinding to the wedge shape sample.Its great advantage is can control comparatively accurately the angle of inclination of wedge shape sample, thereby increases the efficient of sample preparation, and improves the uniformity that sample grinds.
Description of drawings
Fig. 1 is structure cutaway view of the present utility model.
Fig. 2 is structure vertical view of the present utility model.
Fig. 3 is the structure vertical view of right angle terrace with edge.
Fig. 4 is the structure left view of right angle terrace with edge.
Among the figure: 1 cylindrical base; 2 cylinder pillars; The 3-1 cylindrical sleeve; The 3-2 screw rod; 4 right angle terrace with edges; 5 differential heads; 6 samples; 2/7ths three manholes; 8 semi-circular recesses.
The specific embodiment
Be described in detail specific embodiment of the utility model below in conjunction with technical scheme and accompanying drawing.
Embodiment
As shown in Figure 1 and Figure 2, a kind of grinding and polishing device for the transmission electron microscope film sample, three cylinder pillars 2 be around the equidistant even distribution in the center of circle, cylindrical base 1 bottom, and with cylindrical base 1 on corresponding through hole be slidingly matched; Three rotary screws comprise cylindrical sleeve 3-1 and screw rod 3-2 two parts, and wherein respective through hole is fixedlyed connected by screw on cylindrical sleeve 3-1 and the cylindrical base 1, and cylindrical sleeve 3-1 center has tapped through hole, can be for screw rod 3-2 turnover;
The through hole corresponding with cylindrical base 1 central through hole arranged on this right angle terrace with edge 4, utilize bolt to pass through hole and with nut it is fixedlyed connected with cylindrical base 1; Have semi-circular recesses 8 and 2/3rds manholes 7 on the corner angle outer rim position of right angle terrace with edge 4;
A differential head 5 cooperates with right angle terrace with edge 4, and is fixing by semi-circular recesses 8, and utilizes screw lock.
During operation, three cylindrical sleeve 3-1 of rotary screw are inserted into respectively on the cylindrical base 1 fix in the corresponding through hole and with holding screw, then screw rod 3-2 is screwed in the sleeve.Again cylinder pillar 2 is inserted in the through hole of cylindrical base 1, and regulates three cylinder pillars, 2 outer elongations by regulating rotary screw, make the bottom surface of three cylinder pillars 2 on same horizontal plane.After the leveling, right angle terrace with edge 4 is linked to each other with cylindrical base 1, and fix with screw bolt and nut, again differential head 5 is put on the right angle terrace with edge 4 in the corresponding semi-circular recesses 8, and used screw lock.Again sample 6 is put in 2/3rds manholes 7 of right angle terrace with edge 4.Utilize differential head 5 to regulate the extension of sample 6, after making it to reach the position that needs, with screw lock sample 6.Grind at last.During grinding, the cylinder pillar 2 of this device is placed sand paper or have on the plane of sand paper, carry out linear reciprocating motion by hand-held cylindrical base 1 and sample 6 can be worn into wedge shape, can also do the motion of " 8 " type sample 6 is carried out attenuate and polishing.
