[0048] And through the rotation of clamp 56 can meet the liquid gas separation oil cylinder ring seam welding demand, realize the stable rotation of liquid gas separation oil cylinder, ensure that the weld is uniform, without secondary repair welding, two symmetrically distributed receiving mechanisms 4 are fixedly installed on the upper side of clamping mechanism 5, receiving mechanism 4 includes support column 43, support column 43 is fixedly connected with clamping mechanism 5, support column 43 upper end is fixedly installed with receiving table 42, arc-shaped groove 44 is opened in the inside of receiving table 42, a plurality of rolling rods 41 are rotatably installed on the surface of arc-shaped groove 44 relative to both sides, rolling rod 41 adopts polyether ether ketone, in turn can support liquid gas separation oil cylinder and will not scratch liquid gas separation oil cylinder, at the same time can adapt to welding environment, two symmetrically distributed polishing mechanisms 6 are arranged between two receiving mechanisms 4, polishing mechanism 6 includes fixed plate 61, fixed plate 61 one side is fixedly installed with fixed frame 62, fixed plate 61 and fixed frame 62 can form rigid fixed structure, in turn can avoid the shaking of polishing roller 63 in polishing process, guarantee the polishing precision and welding effect;

[0049] The fixed frame 62 is internally provided with a polishing roller 63. Before welding, the polishing roller 63 can rotate through the oil cylinder for liquid-gas separation to polish and clean the impurities such as oxide scale, rust and burrs in the ring gap area of the oil cylinder for liquid-gas separation, so as to avoid the occurrence of pores, slag inclusion and other conditions in the weld due to impurities, thereby ensuring the strength of the weld, the sealing performance of the oil cylinder for liquid-gas separation and the welding effect. After welding, the polishing roller 63 can polish and shape the weld to make the weld surface smooth and flat, thereby reducing stress concentration and ensuring the welding effect. The polishing roller 63 is fixedly installed with a rotating shaft 64 in the middle. When the rotating shaft 64 drives the driving disc 910 to rotate, the compression block 912 compresses air in the chamber 99 and discharges the air outward. Since the air discharge speed is slow, an air damping buffer effect is formed, which can make the rotating speed of the polishing roller 63 lower than the rotating speed of the oil cylinder for liquid-gas separation, so as to avoid damage to the surface of the oil cylinder for liquid-gas separation or the weld due to the too high rotating speed of the polishing roller 63, and the vibration generated by high-speed rotation and polishing. At the same time, it can also make the polishing force more uniform and softer, thereby improving the roughness consistency of the polished surface and ensuring the polishing effect and welding effect.

[0050] The rotating shaft 64 extends to the inside of the running body 93 at both ends, and the rotating shaft 64 is fixedly connected with one side surface of the driving disc 910 at both ends. The rotating shaft 64 penetrates to the outside of the fixed frame 62 at both ends, and the rotating shaft 64 is rotatably connected with the inside of the fixed frame 62 outside. The opposite sides of the two polishing mechanisms 6 are provided with buffer mechanisms 9. The buffer mechanism 9 comprises a fixed body 91 and a running chamber 98 opened in the inside of the fixed body 91. The fixed body 91 penetrates to open an exhaust hole 92 on one side. The fixed body 91 is two groups, and each group has two. The lower side surface of the fixed body 91 penetrates to open a gas inlet hole 97. The gas inlet hole 97 is a plurality of. The opposite sides of the inner wall of the running chamber 98 are fixedly installed with a running body 93. The running body 93 penetrates to open a gas inlet hole 95 and an air outlet hole 94 outside. The air outlet hole 94 is fixedly installed with an exhaust pipe 96. The exhaust pipe 96 penetrates the air outlet hole 92 and extends to the outside of the fixed body 91. The gas inlet hole 95 and the air outlet hole 94 are symmetrically distributed. The inside of the running body 93 is provided with a chamber 99. The inner wall of the chamber 99 is in sliding connection with the peripheral side of the compression block 912.

[0051] The inner wall of the chamber 99 is in sliding connection with the circumferential side of the driven disc 911, the chamber 99 is internally provided with the driving disc 910 and the driven disc 911, the diameter of the driving disc 910 is greater than that of the driven disc 911, and the driving disc 910 and the driven disc 911 are tangent, the driving disc 910 is externally fixedly installed with the compression block 912, the driving disc 910, the driven disc 911 and the compression block 912 are made of polyether ether ketone material, thereby ensuring the sealing of the tangent point of the driving disc 910 and the driven disc 911, the sealing between the compression block 912 and the chamber 99, and reducing the friction between the compression block 912 and the chamber 99, the compression block 912 can be engaged with the groove 913, thereby ensuring the continuous rotation of the driving disc 910, the driven disc 911 is externally provided with the groove 913, the polishing mechanism 6 and the buffering mechanism 9 are located between the two receiving mechanisms 4, the welding mechanism 3 is fixedly installed on the inner wall of the operation bin 2, the welding mechanism 3 comprises a sliding rod 31, the sliding rod 31 is externally in sliding connection with a sliding block 32, the sliding rod 31 ensures the transverse movement of the welding head 34 and the longitudinal lifting of the adjusting block 33, thereby being capable of forming the ability of three-dimensional movement, quickly aligning the welding position, and thereby being capable of adapting to the oil cylinder of different diameters for liquid-gas separation, and solving the problems of complicated adjustment and inaccurate positioning of the traditional welding head 34;

[0052] The sliding block 32 is in sliding connection with the adjusting block 33 on one side, the adjusting block 33 is fixedly installed with the welding head 34 at the lower end, the opposite ends of the sliding rod 31 are fixedly connected with the inner wall of the operation bin 2, the welding mechanism 3 is located on the upper side of the polishing mechanism 6, the base 1 is internally provided with a collection bin 11, the collection bin 11 is internally in sliding connection with a collection box 12, the welding operation station can control the welding mechanism 3 and the clamping mechanism 5, and the control mode of the welding operation station and the control of the welding mechanism 3 and the clamping mechanism 5 is the prior art, which will not be described herein;

[0053] According to the physical characteristics of gas damping, the size of the damping torque is related to the rotation speed of the driving disc 910, the faster the rotation speed, the higher the frequency of the compression block 912 extruding the gas, the greater the pressure of the chamber 99, and the greater the damping torque, and vice versa;

[0054] If the rotation speed of the oil cylinder for liquid-gas separation is accelerated, the rotation speed of the polishing roller 63 will have a trend of acceleration, the damping torque increases, and the polishing roller 63 is hindered from accelerating, and finally the rotation speed of the polishing roller 63 is still lower than that of the oil cylinder for liquid-gas separation;

[0055] If the rotation speed of the oil cylinder for liquid-gas separation is slowed down, the rotation speed of the polishing roller 63 will only have a trend of slowing down, at this time the damping torque will decrease but still exists, so the rotation speed of the polishing roller 63 is still less than that of the oil cylinder for liquid-gas separation, at this time the speed difference still exists.

[0056] Working principle: when the welding of the ring joint of the oil cylinder is continued, the oil cylinder is first clamped and fixed by the clamp 56, and then the welding joint is butt jointed by moving the supporting table 51, and the outer side of the oil cylinder is in contact with the rolling rod 41 and the polishing roller 63. When the butt joint is completed, the clamp 56 is started to rotate, and the oil cylinder rotates under the support of the rolling rod 41, and the rolling rod 41 rotates at the same time. At this time, the polishing roller 63 is driven by the oil cylinder, and when the polishing roller 63 rotates, the rotating shaft 64 starts to rotate, which can rotate the driving disc 910. At this time, the driving disc 910 rotates the driven disc 911 tangent to it, and the compression block 912 rotates with the driving disc 910. At this time, the compression block 912 expels the gas between it and the gas outlet hole 94 outward from the gas outlet hole 94. Because the rotating speed of the oil cylinder is greater than the exhaust speed of the gas outlet hole 94, the rotating speed of the driving disc 910 is lower than that of the oil cylinder, and the rotating speed of the rotating shaft 64 and the polishing roller 63 is lower than that of the oil cylinder. At this time, the contact surface of the oil cylinder and the polishing roller 63 produces friction, and the polishing roller 63 polishes the welding joint of the oil cylinder. At the same time, the compression block 912 rotates and engages with the groove 913, so that the driving disc 910 can continue to rotate to avoid mechanical operation interference of the driven disc 911. The air inlet 95 is in contact with the outside world, and the normal air pressure is maintained between the air inlet 95 and the compression block 912. When the compression block 912 engages with the groove 913, it will be separated again. After the compression block 912 moves past the air inlet 95, a sealed space is formed between the compression block 912 and the gas outlet hole 94, so that the continuous gas damping effect is achieved, thereby ensuring the rotating speed of the rotating shaft 64, reducing the vibration and excessive wear caused by high-speed polishing, and ensuring the welding quality and stability. The exhaust gas is sprayed from the exhaust pipe 96 to the welding joint of the oil cylinder, so as to clean the impurities polished off and attached to the welding joint of the oil cylinder, ensure the cleanliness of the welding joint and the effect of welding pretreatment. When the polishing pretreatment of the welding joint of the oil cylinder is completed, the welding mechanism 3 is started, and the sliding block 32 and the adjusting block 33 move under the support of the sliding rod 31, so that the welding head 34 can be aligned with the welding joint, and then welding is carried out. When welding, the welded welding joint will move to the polishing roller 63 under the rotation of the oil cylinder, and then the above steps are repeated to polish the welded welding joint, so as to clean the welding slag, burr and other impurities, ensure the smoothness of the welding joint, and then the impurities are dropped into the guide cylinder 13, and then into the collecting bin 11, and then into the collecting box 12, so as to complete the collection of the impurities.

[0057] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
