Problems solved by technology
[0007] Usually in the test process, manual loading and unloading weights are used. On the one hand, the labor intensity is high, and on the other hand, the loading and unloading mass cannot be quickly and accurately loaded. The loading mass is very sensitive to the test results, so there will be problems caused by test operations. The result error, this problem has always existed in the use of the instrument, and has not been effectively solved. Therefore, we propose an electric lifting mechanism for thermal deformation and Vicat softening point temperature measuring instrument to solve the above-mentioned problems.

The invention discloses an electric lifting mechanism of a thermal deformation and vicat softening point temperature tester, and belongs to the technical field of testers. The electric lifting mechanism is technically characterized by comprising an electric lifting cylinder, a lifting cross beam at the top of the electric lifting cylinder, a weight rack lifting rod connected with two ends of the lifting cross beam and a test rack lifting pipe sleeved on the weight rack lifting rod. And the weight rack lifting rod and the test rack lifting pipe are respectively connected with the weight rack and the test rack. According to the invention, two test operation processes are realized in two continuous steps through one electric lifting cylinder. According to the invention, two test operation processes are realized through one electric lifting cylinder. The process is reasonable, the action is stable, the mechanism is simplified, and two tasks of lifting the sample holder and the weight frame are completed by one set of mechanism. The problem that dozens of kilograms of counterweights are loaded and unloaded manually and frequently is solved, the labor intensity of an operator is greatly relieved, the working efficiency is improved, automatic control of the test process can be achieved in cooperation with an electrical control system, and the automation level of an instrument is improved.
Description
technical field [0001] The invention belongs to the technical field of measuring instruments, and in particular relates to an electric lifting mechanism of a thermal deformation and Vicat softening point temperature measuring instrument. Background technique [0002] Thermal deformation and Vicat softening point temperature measuring instrument is mainly used for thermal deformation temperature measurement and Vicat softening point temperature measurement of plastic, rubber, nylon, electrical insulation materials and other non-metallic materials. One instrument can do two kinds of tests. It is a commonly used testing instrument in the production process of various non-metallic materials. [0003] The heat deflection temperature of various materials refers to the temperature when the standard sample is subjected to a three-point bending constant load, so that it produces a certain bending stress, and under the condition of uniform temperature rise, the standard deflection cor...
