The invention discloses an internal pull type manufacturing method of a coaxial thermocouple transient heat flow sensor, comprising: passing a traction rope through a sensor tubular shell with an opening, stretching the sensor wire core through the traction rope and pulling the sensor wire core Piercing into the tubular shell of the sensor, cutting the tubular shell of the sensor and the sensor wire core pierced therein together. It avoids the disadvantages that the sensor wire core is prone to be bent and broken during the process of penetrating into the sensor tubular shell, and avoids the limitation of the length of the sensor wire core that can be pierced by means of insertion or the like. Due to the limitation of the parameters of the wire threading equipment, it is possible to process a long section of the heat flow sensor prototype, and the sensor tubular shell with the sensor wire core is cut in sections to quickly process multiple heat flow sensor prototypes, thereby The processing efficiency of the coaxial thermocouple transient heat flow sensor is greatly improved.
Description
Technical field [0001] The present invention relates to the field of heat flow sensor processing, and more particularly to a coaxial thermocouple transient thermal flow sensor of a macrotransmary production method. Background technique [0002] Coaxial thermocouple transient heat flow sensor is a kind of experimental components that form an electric potential under different temperature gradients using different electrode materials and to measure, and then inverse temperature and heat flow, mainly for aerospace high ultrasound speed aircraft Pneumatic experiment, high ultrasound flow related experiment, etc., has the characteristics of fast response, large range, high precision, robustness. [0003] At present, when machining coaxial thermocouple transient heat flow sensors, the sensor wire core is needed to be in the sensor tubular housing and fixed, since the filamental tubular housing of the sensor tubular housing is small, resulting in sensor wire In the core sensor tubular s...
