Summary of the invention
According to the above technical problem, the utility model provides a kind of transmission shaft and pressure sensor combined mechanism, feature
It is to include slip ring (1), pressure sensor housing (2), pressure sensor fixed frame (3), pressure sensor (4), driving key
(5), transmission shaft (6), the pressure sensor housing (2) are provided with pressure sensor fixed frame (3) and pressure sensor (4),
Transmission shaft (6) center is equipped with guide hole, and the pressure sensor (4) is surveyed by the guide hole at transmission shaft (6) center
The pressure of outside liquid is measured, is equipped with cable-through hole in the pressure sensor housing (2), obtained measuring signal is led to by data line
Cable-through hole and slip ring (1) in excess pressure sensor outer housing (2) send data acquisition board to.
The pressure sensor housing (2) is connected into one by two symmetrical driving keys (5) and transmission shaft (6)
Body.
Transmission shaft (6) left end is equipped with built in pressure sensor (4), and axis center has a guide hole, and the guide hole will
The pressure of outside liquid directs into pressure sensor (4).
There is a cable-through hole in the pressure sensor housing (2), the signal wire of the pressure sensor (4) passes through cable-through hole
It is connected in the inner ring of slip ring (1), then signal wire is connected on the external circuit board by the outer ring of slip ring (1).
The pressure sensor (4) is equipped with analog-to-digital conversion module, the analog signal that will be measured by analog-to-digital conversion module
It is directly changed into digital signal, then digital signal is transferred to data acquisition board by signal wire.
The utility model has the following beneficial effects:
1) pressure sensor housing (2) is coupled integrally by two symmetrical driving keys (5) with transmission shaft (6),
It is set to have the function of measurement outside liquid pressure while having passing movement and torque function；
