Abstract
The utility model discloses a kind of equipment for quickly preparing transmission electron microscope thin slice sample, for preparing pre- thinned sample in laboratory.It is interference fitted including driven gear and main shaft, micro actuator, moving gear, thrust bearing, washer, spring limits main shaft length travel, and upper limit sleeve and lower limit sleeve limit main shaft lateral displacement.Make pressure head by the blind hole in sample indentation objective table by adjusting coarse adjustment mechanism, motor provides power by gear drive for main shaft, and adjustment micro actuator makes to be connected to the grinding sample of the milling cutter microfeed on main shaft.The utility model can replace manual sample grinding, easy to operate, and grind away speed is fast, and is hardly damaged sample.
Description
Technical field
The equipment that the utility model is used to prepare transmission electron microscope thin slice sample in the lab.
Background technique
Transmission electron microscope sample preparation plays a crucial role in metal and associated materials research work, to obtain
Good experimental result, it is necessary to which the sheet metal specimens prepared, traditional preparation method are to first pass through manual sample grinding, keep sample thick
Degree reaches 30-50 μm thin instrument processing, and ion milling is expensive when handling, and the thicker sample thinned time is longer, and price is thinned
It is more expensive.Since sample used is small and thin, extremely inconvenient, sample of easily grinding away when manual sample grinding is to 30-50 μm.
Utility model content
In order to solve the problems, such as manual sample grinding difficulty, the utility model provides a kind of simple grind away device, and the device is not only
Grind away speed is fast, and can control grinding depth, and is hardly damaged sample.The utility model is used for the above purpose
Technical solution is:
In order to which sheet metal specimens are fixed on objective table, it is provided with blind hole on objective table, sample is put into blind hole center, then
Adjusting the coarse adjustment knob in rack makes the longitudinal substantially movement of casing compress pressure head by sample.Pressure head is to be threadedly coupled with casing.
Coarse adjustment mechanism be by be mounted on casing coarse adjustment folder in gear and rack-mounted rack gear constitute.Pressure head and objective table
On blind hole it is coaxial.
Driven gear is held up upwards by thrust bearing, washer, spring, withstands on main shaft on ball and micro actuator upwards, main
Axis lower end installs fixture, fixture are used to clamp milling cutter.Main shaft is used with fixture and is threadedly coupled.Driven gear is installed on main shaft, it is main
Axis and driven gear are interference fitted.Driven gear is held up upwards by thrust bearing, washer, spring, and spring bottom end is fixed on body
On.Micro actuator, main shaft, fixture, pressure head, coaxially.Driving gear is driven by motor, and driving gear and motor shaft are interference fitted.Mill
When cutting, micro actuator is slowly adjusted, feeds main shaft slowly to be ground sample.
Utility model has the advantages that grind away speed is fast, saves the time, is easy to control grinding when with the device grind away
Amount, can be milled to 10-20 μm for sample, to reduce ion milling expense.

Specific embodiment
In Fig. 1, casing (20) is mounted on rack (19) by coarse adjustment mechanism (18).Rack gear in micro-adjusting mechanism
(18.3) it is fixed on rack (19), coarse adjustment folder (18.4) is fixed on casing (20), can by adjusting coarse adjustment knob (18.1)
So that casing (20) longitudinally substantially moves.Micro actuator (1) is the measuring head of spiral micrometer, and it is vertical to be used to accurate control main shaft (2)
To micro-displacement.Shown in Fig. 4, micro actuator, ball, sleeve constitutes upper limit sleeve (17), can be with lower limit sleeve (11)
Limit main shaft (2) lateral displacement.Lower limit sleeve is fixed on casing (20).Driven gear (6) and main shaft (2) are interference fitted.
Driven gear (6) is held up upwards by thrust bearing (8), washer (9), spring (10), and main shaft (2) is made to withstand on ball and fine tuning upwards
On device (1).Fixture (12) clamps milling cutter (14) and is threadedly attached on main shaft (2).Pressure head (13) is threadedly attached in machine
On shell (20).When replacing milling cutter (14), first pressure head (13) is unloaded, unclamps again fixture (12).Motor (3) is fixed on casing
(20) on, driving wheel (7) and motor shaft are interference fitted.
Print thickness first is measured with spiral micrometer using preceding, thickness value is recorded, calculates processing capacity.It adjusts micro actuator (1)
Flush milling cutter (14) with pressure head (12) bottom end.Then ready print is put into the blind hole on objective table (15), is adjusted
Coarse adjustment knob (18.1) makes pressure head (13) to compress print.It turns on the switch (4), adjusts speed regulation knob (5) and adjust to suitable revolving speed.
Then adjusting micro actuator (1) makes main shaft (2) microfeed, until reaching required result.
