Piezoelectric material constant-temperature polarization equipment for laboratory

Abstract

The invention discloses piezoelectric material constant-temperature polarization equipment for laboratory, which structurally comprises a constant-temperature bin, a supporting rod, a fixed platform, a detector and a polarization device, the periphery of the bottom end of the supporting rod is embedded into the four corners of the top end of the constant-temperature bin, and the interiors of the four corners of the fixed platform are clamped to the periphery of the supporting rod; the lower end of the detector is connected to the middle of the left side of the upper surface of the fixed platform through a bolt, the periphery of the upper portion of the polarization device is connected to the center of the interior of the right side of the fixed platform in an embedded mode, and the detector is electrically connected with the polarization device. According to the invention, when the polarization block extrudes the piezoelectric material, the probe can stretch out and draw back in a large range under the cooperation of the spring. Further, scraping blocks in the fixing mechanism can rise under the limitation of limiting blocks and stretch towards the two sides at the same time, kerosene on the contact surface is scraped in the stretching process, a movable rod in the contact mechanism is driven by a push rod to extrude an air bag, and then the air bag deforms to push the contact blocks to make contact, so that the friction force of the contact point is increased.

[0002] Piezoelectric material is a kind of crystalline material whose surface is subjected to pressure and internal polarization will generate voltage. Because of its piezoelectric characteristics, it is often used in various high-precision instruments and equipment. There are many kinds of piezoelectric materials. In order to accurately test various The precise characteristics of materials generally require polarization tests under constant temperature conditions in the constant temperature polarization equipment for piezoelectric materials used in laboratories, but the constant temperature polarization equipment for piezoelectric materials used in laboratories in the prior art is testing piezoelectric materials During the process, due to the requirement of constant temperature and non-conductivity, the material is generally soaked in a constant temperature chamber filled with kerosene, and when the testing mechanism clamps the material, due to the good lubricity of kerosene, the clamping mechanism will Sliding, resulting in the clamping mechanism not tightly clamping the material, and then there is a phenomenon that the test data and the actual value deviate
