Description
Technical field
The present invention relates to a kind of thermal deformation dimension card analyzer.
Background technology
Thermal deformation dimension card analyzer is for testing macromolecular material vicat softening point temperature and heat distortion temperature, macromolecular material or polymer is applied certain load, heats up with certain speed, the temperature corresponding when reaching regulation deformation.Nonmetallic materials are when doing heat distortion temperature and measuring, the full payload that sample bears includes the weight such as pressure head, load beam, weight tray, existing thermal deformation dimension card measuring instrument uses the compound mode of displacement measurement bar and dial gauge to carry out displacement measurement, but this kind of mode measurement result is not accurate enough, easily cause error, thus affect the certainty of measurement of thermal deformation dimension card measuring instrument.
Summary of the invention
For drawbacks described above, it is an object of the invention to provide a kind of simple in construction, easy to operate, certainty of measurement a kind of thermal deformation dimension card analyzer accurately.
For this technical solution adopted in the present invention it is:
Including bath, the specimen mounting that can place sample it is provided with in described bath, the upper end of described bath is provided with support bar, support seat it is socketed with on described support bar, described support seat can move up and down, the front end of described support seat is provided with displacement transducer, institute's displacement sensors is vertically downward, the lower section of displacement transducer is provided with weight tray, described weight tray lower end is connected with the upper end of load beam by screw thread, the upper surface of described weight tray and the lower end in contact of displacement transducer, the lower end of load beam has been threaded connection pressure head, described pressure head is pressed in sample upper surface, described specimen mounting is provided with thermometer.
Further, the rear end of described support seat is provided with holding screw, and described holding screw is used for being fixedly connected support seat with support bar.
The invention have the advantage that
Present configuration is simple, easy to operate, and by using displacement transducer can accurately measure displacement, dependability is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure 1 be bath, 2 be sample, 3 be specimen mounting, 4 be support bar, 5 be support seat, 6 be displacement transducer, 7 be weight tray, 8 be load beam, 9 be pressure head, 10 be thermometer, 11 be holding screw.
Detailed description of the invention
A kind of thermal deformation dimension card analyzer, including bath 1, the specimen mounting 3 that can place sample 2 it is provided with in described bath 1, the upper end of described bath 1 is provided with support bar 4, support seat 5 it is socketed with on described support bar 4, described support seat 5 can move up and down, the front end of described support seat 5 is provided with displacement transducer 6, institute's displacement sensors 6 is vertically downward, the lower section of displacement transducer 6 is provided with weight tray 7, described weight tray 7 lower end is connected with the upper end of load beam 8 by screw thread, the upper surface of described weight tray 7 and the lower end in contact of displacement transducer 6, the lower end of load beam 8 has been threaded connection pressure head 9, described pressure head 9 is pressed in sample 2 upper surface, described specimen mounting 3 is provided with thermometer 10.
Further, the rear end of described support seat 5 is provided with holding screw 11, and described holding screw 11 is used for being fixedly connected support seat 5 with support bar 4..
After weight tray 7 is forced into sample 2 with certain pressure, support seat 5 is carried out upper and lower trace and moves, when supporting seat 5 and being adjusted to desired location, locked by holding screw 11, then displacement transducer 6 is carried out checking for zero.
