Detailed description of the invention
Referring to the drawings, nanometer press fit instrument cooling platform, including base 1, pan frontward end opening, lifting platform 4 embeds base
In, the front end face of lifting platform is coordinated by corner structure with base；Heat radiation copper bar 9 is embedded in lifting platform, and cooling piece 8 generates heat end
Contacting with heat radiation copper bar, the refrigeration end of cooling piece contacts with thermocouple 5, and thermocouple contacts with object stage 6, and heat insulation bolt 71 will carry
Thing platform, thermocouple, cooling piece and heat radiation copper bar are fixed on lifting platform；Base offers U-lag 10, cooling piece and thermoelectricity
Even connecting line is placed in U-shaped wire casing；Offer waist-shaped hole 3 at base side wall, lifting platform is provided with screwed hole, regulate spiral shell 72 bolt
Coordinated with the screwed hole of lifting platform by waist-shaped hole.
Owing to base is the structure of one end open, for the installation with radiating copper row's component.
The design of corner structure so that coordinated with rear end face conflict by turning between lifting platform with base, make both not
Can occur front and back to topple, it is ensured that lifting platform regulates with the vertical height of base.Corner structure i.e. arranges one at the front end face of base
Vertical boss, offers the breach coordinated with boss on lifting platform, makes the vertical front end face 2 of breach and the vertical end of boss
Face coordinates, and in conjunction with the coordinating of vertical plane of lifting platform and the rear end face of base, thus topples before and after can preventing lifting platform.
The setting of waist-shaped hole, makes bolt can move up and down in waist-shaped hole, it is convenient to regulation lifting platform is on base
Highly.Unclamping bolt, can move up and down lifting platform, when lifting platform arrives suitably height, then screwing bolts is on base
Fixing lifting platform.
Heat insulation bolt used in this utility model, its material is not that transcalent ferrous material makes, but generally
Carried out making by rubber, can be the most heat insulation, say, that heat insulation bolt is to make of the non-conductor of heat.
Temperature-controllable in the present embodiment: 0 ° of C--50 ° of C, DC source: 12V, 6A.
Operation principle: by the waist-shaped hole on base, unscrews regulation bolt and adjusts the height of lifting platform.Cooling piece is led to
Electricity, two ends will produce heat transfer, and heat will be transferred to the other end, thus produce the temperature difference and form cold and hot end from one end.Its
In, to send out hot-side temperature and drastically raise, heat is delivered to the copper bar that dispels the heat, and circulate in heat radiation copper bar cold water, and cold water is by small-sized cooling-water machine
Supplying, circulating chilled water takes away the heat that cooling piece produces, and the temperature of cold water is adjustable between 5 ° of C to 35 ° of C.At a temperature of refrigeration end
Fall, directly results in object stage temperature and declines, and the specimen temperature being bonded on object stage is declined, As time goes on,
The temperature difference at cooling piece two ends tends towards stability, and sample is in stable low temperature environment.
Control the temperature of refrigeration since size by change DC current, thus regulate the temperature of laboratory sample, finally
The mechanical property of sample is measured by nanometer press fit instrument.
