Abstract

The invention discloses a double-layer heat-insulation box body structure for a low-temperature friction-wear tester. The double-layer heat-insulation box body structure is characterized by comprising an inner-layer heat-insulation box body, an endoscope and illumination system, an outer-layer heat-insulation box body, an outer-layer heat-insulation box door, an illumination lamp, temperature sensors, a control display module and humidity detection sensors, wherein the endoscope and illumination system is arranged in the inner-layer heat-insulation box body; the inner-layer heat-insulation box body and the illumination lamp are arranged in the outer-layer heat-insulation box door; the control display module is arranged at an upper part outside the outer-layer heat-insulation box door, and used for acquiring the signals of the temperature sensors, the humidity detection sensors and the endoscope, and displaying a temperature, a humidity and endoscope images. The double-layer heat-insulation box body is provided for the low-temperature friction-wear tester for a grinding tool for an ice pin, the problems of the temperature recovery in the box body and the thawing of the ice pin, which are brought during clamping and trimming for the ice pin, are solved, and a working environment fully filled with a protective gas can be provided.

Description

technical field [0001] The invention relates to an insulated box of a low-temperature friction and wear testing machine, in particular to a double-layer insulated box suitable for the low-temperature friction and wear testing machine of ice pin abrasive tools. Background technique [0002] The friction and wear testing machine adopts the principle of microcomputer control, LCD dynamic display, and mechatronics to carry out the set friction test. Before the test, the friction times required by the test standard or determined by the operator are input into the control system, and the actuator uses a high-precision gear reduction micro-motor to drive the friction body to perform linear reciprocating or circular friction motion. The friction and wear testing machine has guiding significance for the study of material properties, material wear during work, and material removal mechanism. [0003] At present, in the field of aerospace, it is necessary to study the wear of parts in...
