Abstract

The invention discloses a micro thermocouple threading device and a machining method, and belongs to the technical field of thermocouple manufacturing. The micro thermocouple threading device comprises a material storing and feeding mechanism, a thermocouple wire clamping mechanism, a wire feeding mechanism, a welding mechanism, a shearing mechanism and a machining platform, wherein the material storing and feeding mechanism conveys a U-shaped quartz long tube to a threading area above the machining platform; the wire feeding mechanism enables a traction wire to penetrate through the U-shaped quartz long tube and conveys the traction wire to a welding area above the machining platform; the thermocouple wire clamping mechanism is used for clamping a thermocouple wire and conveying the thermocouple wire after length comparison to the welding area above the machining platform to form lap joint with the thermocouple wire in the welding area; the welding mechanism is used for welding the thermocouple wire and the traction wire in the welding area; and the shearing mechanism shears off the redundant traction wire after the welded thermocouple wire and the traction wire move to the designated position, and therefore threading work is completed. Manual errors can be reduced, the threading efficiency is greatly improved, the production cycle of thermocouple products is shortened, and the labor intensity of operators is reduced.

Description

technical field [0001] The invention belongs to the technical field of thermocouple manufacture, and more specifically relates to a fine thermocouple wire threading device and a processing method. Background technique [0002] Thermocouple is a commonly used temperature measuring element in temperature measuring instruments. Thermocouple is widely used. It has many advantages such as simple structure, convenient manufacture, good interchangeability, wide measurement range, high precision, small inertia and easy remote transmission of output signal. It has a wide range of applications in various fields of national economic development. It welds two thermocouple wires of different materials together, and the two ends are interconnected. When the temperature at the two nodes is different, a thermoelectric potential will be generated at the node, that is, the temperature signal is converted into a thermoelectric potential signal, which is passed through the electrical instrument...
