1. A friction and wear test device for realizing pin-on-plate differential temperature distribution and self-adaptive adjustment, comprising a high temperature heating chamber and a cooling pin, wherein
the high temperature heating chamber is fastened horizontally to a mobile base;
an axis of the cooling pin is perpendicular to an upper surface of the mobile base;
the cooling pin contacts a friction sample plate through a hole of an insulation cover located on a top of the high temperature heating chamber;
an electric resistance heating plate is located in a bottom closed space under the friction sample plate in the high temperature heating chamber;
an electric resistance heating is used to heat the friction sample plate to an experiment temperature;
a circulating cooling channel is arranged inside the cooling pin;
a cooling medium in the circulating cooling channel adjusts and cools a temperature of a sample;
a first thermocouple and a second thermocouple, distributed separately in a temperature measuring groove of the high temperature heating chamber and a temperature measuring hole of the cooling pin, and are configured to measure the temperature in real time;
wherein the high temperature heating chamber comprises the insulation cover, the friction sample plate, a briquetting, a support block, a ceramic plate, the electric resistance heating plate, a thermal insulation fiber, a support shell, a thermal insulation shell, a thermal insulation base, a cushion block, the temperature measuring groove, a base, and the mobile base; wherein
electric resistance wires are disposed in the electric resistance heating plate;
the friction sample plate is fixed in a square groove of the support block under a pressure of the briquetting which is connected with the support block by screws;
the support block is connected to the support shell by screws;
a lower surface of the support block is in contact with an upper surface of the ceramic plate;
the ceramic plate is located on an upper surface of the electric resistance heating plate;
an outer wall of the ceramic plate is in contact with an inner wall of the support shell;
a bottom of the thermal insulation shell is connected to a side wall of the thermal insulation base by screws;
the support shell is connected to the thermal insulation base by screws;
the thermal insulation shell and the support shell are connected by bolts;
the cushion block is located in a square groove of the thermal insulation base;
the thermal insulation base is connected with the base by screws, and the base is connected with the mobile base by screws;
the electric resistance heating plate is installed on a stepped surface of the thermal insulation base and an upper plane of the cushion block;
the ceramic plate and the support block are provided with through-holes below the friction sample plate; and
the electric resistance heating plate heats the friction sample plate by a heat radiation of the through-holes and a heat conduction of the ceramic plate and the support block.
