The automatic pressure regulating mechanism is jacked up to the gas proportional valve positioning tooling by the electric cylinder or air cylinder. After the pressure regulating rod and the locking sleeve coincide with the pressure regulating screw of the gas proportional valve, the locking servo motor is driven to reverse to loosen the locking nut of the gas proportional valve. Then, the position of the locking nut of the gas proportional valve is fixed by the constant torque and control pulse of the locking servo motor. By the forward and reverse rotation of the pressure regulating servo motor, the pressure of the gas proportional valve is adjusted to the set value. Then, the pressure regulating screw of the gas proportional valve is fixed by the constant torque and control pulse of the pressure regulating servo motor. Finally, the locking servo motor rotates forward, and the nut of the gas proportional valve is locked by controlling the torque in torque mode so that the torque value of the tightened nut reaches the set torque value, completing the automatic pressure regulation. This solves the problem that the traditional detection and debugging of gas proportional valves rely on manual jigs to position the proportional valves, then the proportional valves are powered on and ventilated, and the proportional valves are adjusted to the set pressure value by manual screwdrivers and wrenches used by workers, and then the adjusting nuts of the proportional valves are locked and fixed. Due to the differences in the proficiency of operators and personal hand feelings, there will be deviations in the pressure value and locking torque after each proportional valve is adjusted.

[0032] Working principle:

[0033] The present invention can achieve 360° omnidirectional installation at various angles according to the external dimensions and characteristics of the gas proportional valves of each manufacturer. During use, it cooperates with an external electric cylinder or air cylinder to achieve lifting and contraction, and cooperates with an external guiding linear bearing for guiding and positioning. The automatic pressure regulating mechanism is lifted to the gas proportional valve positioning tooling through the electric cylinder or air cylinder, so that the pressure regulating rod 23 and the locking sleeve 39 coincide with the pressure regulating screw of the gas proportional valve;

[0034] By driving the reverse rotation of the locking servo motor 37, the locking servo motor 37 drives the locking reducer 33 to rotate. The locking reducer 33 drives the gear transmission shaft 6 to rotate. The gear transmission shaft 6 drives the second cylindrical gear 8 to rotate. The second cylindrical gear 8 drives the first cylindrical gear 12 to rotate through the meshing of teeth. The first cylindrical gear 12 drives the outer guiding sleeve 11, the outer guiding rod 14 and the locking sleeve 39 to rotate in sequence, loosening the locking nut of the gas proportional valve, and then fixing the position of the locking nut of the gas proportional valve through the constant torque and control pulses of the locking servo motor 37;

[0035] By the forward and reverse rotation of the pressure regulating servo motor 38, the pressure regulating servo motor 38 drives the pressure regulating reducer 34 to rotate. The pressure regulating reducer 34 drives the inner guiding sleeve body 17 to rotate through the coupling 21 and the adapter rod body 18. The inner guiding sleeve body 17 drives the pressure regulating rod 23 to rotate, regulating the pressure of the gas proportional valve to the set value, and then fixing the pressure regulating screw of the gas proportional valve through the constant torque and control pulses of the pressure regulating servo motor 38;

[0036] Finally, by the forward rotation of the locking servo motor 37, the nut of the gas proportional valve is locked by controlling the torque in the torque mode, so that the torque value of the tightened nut reaches the set torque value, completing the automatic pressure regulation;

[0037] After manual feeding, one-key start or cooperation with a manipulator is used to achieve full-automatic pressure regulation and locking fixation, greatly improving work efficiency and reducing manual operation, ensuring the consistency of product performance, and solving the problem that the traditional detection and debugging of gas proportional valves rely on manual jigs to position the proportional valves, then power on and ventilate the proportional valves, and manually use a manual screwdriver and wrench to adjust the proportional valve to the set pressure value, and then lock and fix the adjusting nut of the proportional valve. Due to the differences in the proficiency and personal touch of the operators, there will be deviations in the pressure value and locking torque after each proportional valve is adjusted;

[0038] Moreover, the present invention is internally provided with a pressure regulating buffer spring 26 and a locking buffer spring 29, which can relieve the impact on the gas proportional valve and the automatic pressure regulating mechanism during the automatic pressure regulation process, achieve part protection, and further improve the overall practicability.

For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to enumerate all implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
