All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention comprises the following steps: referring to fig. 1 to 3, an a41X type breathing safety valve disassembling and assembling machine includes a frame 1, a rotating shaft 3 rotatably connected to the center of the frame 1, a motor 2 fixedly mounted at the bottom of the frame 1, an output shaft of the motor 2 in transmission connection with the lower end of the rotating shaft 3 through a sprocket mechanism 12, a valve cover positioning seat 4 disposed at the top of the frame 1, a bottom of the valve cover positioning seat 4 fixedly connected to the upper end of the rotating shaft 3, a circular groove disposed on the valve cover positioning seat 4, two rectangular slots 401 symmetrically disposed on the inner wall of the circular groove, two brackets 10 symmetrically disposed at the top of the frame 1 and on both sides of the rotating shaft 3, a top plate 9 fixedly connected between the tops of the two brackets 10, an inverted cylinder 8 fixed at the bottom of the top plate 9, a pressure head 7 fixed at the end of the cylinder 8, an auxiliary clamp 6 disposed between the two brackets 10, the auxiliary fixture 6 comprises a pressure plate 601 and stop rods 602 symmetrically fixed at two ends of the pressure plate 601, and positioning pins 603 are symmetrically and fixedly mounted at the bottom of the pressure plate 601. The cylinder 8 is connected with an air compressor through a pressure regulating valve. The pressing plate 601 is an 3/4 circular disc-shaped plate. And the lower end of the pressure head 7 is fixedly connected with a thrust ball bearing 11.
The working principle of the invention is as follows:
referring to fig. 4 to 6, the a41X type breathing safety valve is composed of a valve body 501, a valve core 503, a valve cover 504 and a spring 506, four bolt holes 502 are uniformly distributed on the valve body 501, and two bosses 505 are symmetrically arranged on the outer wall of the valve cover 504, so that the safety valve is disassembled and assembled by taking the bolt holes 502 of the valve body 501 and the two bosses 505 of the valve cover 504 as limiting points.
1. The decomposition working process is as follows:
1.1, inversely placing the A41X type breathing type safety valve into a circular groove on the valve cover positioning seat 4, and matching a boss 505 on the valve cover 504 with a rectangular clamping groove 401 on the valve cover positioning seat 4;
1.2, pressing a pressure plate 601 of the auxiliary fixture 6 on the valve body 501, and inserting two positioning pins 603 at the bottom of the pressure plate 601 into two bolt holes 502 on the valve body 501;
1.3, starting the cylinder 8, pushing out the telescopic rod of the cylinder 8, pressing the pressure head 7 at the end part of the telescopic rod against the bottom surface of the safety valve, further compressing the spring 506, and eliminating the friction force of the threads between the valve body 501 and the valve cover 504, which is increased by the pressure of the spring 506, at the initial stage of decomposition, so as to facilitate subsequent decomposition;
1.4, starting a motor 2, and driving a valve cover positioning seat 4 to rotate through the motor 2; with the screwing-out of the thread between the valve body 501 and the valve cover 504, the distance between the valve body 501 and the valve cover 504 is increased, at the moment, the pressure of the cylinder 8 is increased along with the screwing-out of the thread due to the reverse thrust acting force of the piston stroke of the cylinder 8, and the thread is easily damaged due to the increase of the friction force. Therefore, the invention is provided with the pressure regulating valve, when the valve body rises, the pressure regulating valve is opened and releases pressure, so that the pressure of the cylinder 8 is prevented from being overlarge, and the spring 506 is slowly extended in the decomposition process;
1.5, after the screw thread between valve body 501 and valve gap 504 completely separates, cylinder 8 stops work, and cylinder 8 telescopic link takes off the breather valve after the decomposition because of the exhaust withdrawal, accomplishes the decomposition.
2. The assembly process is as follows:
2.1, placing the fittings of the A41X type breathing safety valve in sequence, and then assembling according to the steps 1.1 and 1.2 in the disassembly process;
2.2, starting the cylinder 8, pushing out the telescopic rod of the cylinder 8, and pressing the pressure head 7 at the end part of the telescopic rod to press the bottom surface of the safety valve;
2.3, after the threads between the valve body 501 and the valve cover 504 are aligned, starting the motor 2, driving the valve cover positioning seat 4 to rotate through the motor 2, and automatically moving the valve body 501 downwards;
2.4, after the valve body 501 and the valve cover 504 are assembled to the standard height, the cylinder 8 stops working, and the telescopic rod of the cylinder 8 retracts due to exhaust, and the breather valve is taken down after the assembly is completed.
3. Principle of operation
Whether the A41X type respiratory safety valve disassembly and assembly machine is disassembled or assembled, the core principle of the disassembly and assembly machine is as follows:
firstly, the pressure of the spring 506 is released, the friction force of the pressure of the spring 506 on the threads is eliminated, the resistance in the disassembly and assembly process is reduced, and the threads are protected to the maximum extent.
And secondly, setting of maximum torque of disassembly and assembly. When the set torque is reached in the disassembly and assembly, the assembly is not disassembled and assembled by force, and other measures are taken for processing, so that the thread damage is avoided.
And thirdly, setting the degree of freedom in the circumferential direction. When the thread is disassembled and assembled, a certain deviation is inevitably generated in the circumferential direction, and the continuous disassembly and assembly after the deviation is generated will cause the expansion of the deviation and the normal disassembly and assembly cannot be realized. The disassembling and assembling machine has certain degree of freedom in the circumferential direction and can be flexibly adjusted along the thread direction all the time.
Fourthly, the security is guaranteed. The pressure regulating valve arranged during the disassembly can relieve the pressure released by the extension of the spring 506, and the potential safety hazard caused by quick release is avoided.
Practice proves that the unit price of the A41X type breathing type safety valve is 2777 yuan, the original detachable proportion is about 30%, the detachable proportion is 95% after adopting a disassembling and assembling machine, about 1000 tank trucks are repaired every year, about 2000A 41X type breathing type safety valves are totally used, and more than 350 ten thousand yuan can be saved.
