Abstract

The invention discloses a lead type thermocouple piston surface temperature measurement connecting rod lead structure. The structure includes a first connecting block connected with a large head end of an engine connecting rod, the first connecting block is connected with a second hinge block, the second hinge block is hinged to a third hinge block, and the third hinge block is connected with a fourth hinge block through a first connecting rod; the fourth hinge block is hinged to a fifth hinge block, and the fifth hinge block is connected with a sixth hinge block through a second connecting rod; and the sixth hinge block is hinged to a seventh hinge block, and the seventh hinge block is fixedly connected to a rack through an eighth connecting block. The lead type thermocouple piston surface temperature measurement connecting rod lead structure has the beneficial effects that up-and-down motion of a thermocouple wire is changed into swing, and the structure is convenient to assemble and disassemble; a change of piston temperature can be measured, and the measured piston temperature is high in accuracy; the cost is low; and the structure can operate at a high speed.

Description

technical field [0001] The invention relates to the technical field of measuring the surface temperature of a lead-type thermocouple piston, in particular to a lead-wire structure of a connecting rod for measuring the surface temperature of a lead-type thermocouple piston. Background technique [0002] The existing lead type thermocouple measuring mechanism for piston surface temperature measurement is based on the engine connecting rod and adopts an auxiliary mechanism to lead the thermocouple wire (1-4) out of the cylinder (1-1) and connect it with the data acquisition circuit. Fix the thermocouple wire (1-4) on the elastic steel band (1-3), and install the steel band firmly on the piston (1-2) with a larger curvature radius. Such as figure 1 shown. [0003] However, this structure is relatively complicated. When disassembling, the piston and connecting rod of the engine need to be disassembled together, which is inconvenient to disassemble, increases the workload, and r...
