[0005] In response to the shortcomings of the existing technology, the present application provides a stainless steel pipe precision welding processing equipment with the advantages of simple structure, easy use and low cost.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a stainless steel pipe precision welding processing equipment, comprising a bracket for installation, a clamp structure provided on the bracket, vertical plates fixedly installed at both ends of the top of the bracket, a guide rod fixedly installed between the two vertical plates, a hydraulic pipe further provided on the outside of the guide rod, a first clamp fixedly installed on the outside of the guide rod, a second clamp fixedly installed on the outside of the hydraulic pipe, and a welding device further provided on the guide rod;

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] See also Figures 1 to 6 In this embodiment, a stainless steel pipe precision welding processing equipment includes a bracket 1 for installation and a clamp structure arranged on the bracket 1. Vertical plates 2 are fixedly installed at both ends of the top of the bracket 1. Two guide rods 3 arranged in front and behind are fixedly installed before the two vertical plates 2. The clamp structure is arranged on the guide rod 3. The guide rod 3 is also provided with a welding device for welding the butt steel pipes.

[0026] In this embodiment, a hydraulic pipe 5 is further provided on the outside of the guide rod 3 , a first clamp 4 is fixedly mounted on the outside of the guide rod 3 , and a second clamp 6 is fixedly mounted on the outside of the hydraulic pipe 5 .

[0027] Specifically, the first clamp 4 and the second clamp 6 have the same structure. Since the hydraulic pipe 5 is movable relative to the guide rod 3, the section of stainless steel pipe clamped by the second clamp 6 can approach and dock with the stainless steel pipe fixedly clamped by the first clamp 4.

[0028] It should be noted that the first clamp 4 is crescent-shaped and faces the bracket 1. A buckle plate 41 is hinged on the top of the first clamp 4 for buckling and fixing the stainless steel tube. One end of the buckle plate 41 is hinged relative to the first clamp 4, and the other end is fastened by a conventional locking structure to facilitate clamping and fixing the stainless steel tube.

[0029] In addition, a number of pads 42 can be detachably installed on the arc-shaped inner wall surfaces of the first clamp 4 and the buckle plate 41, and the sizes of adjacent pads 42 decrease in equal steps to facilitate adjustment of the first clamp 4 for effective clamping of stainless steel pipes of different diameters.

[0030] Preferably, two arc-shaped ridges 43 are raised on the inner wall surface of the pad 42. Through the setting of the ridges 43, the surfaces of adjacent pads 42 are only in contact through the ridges 43, thereby conveniently reducing the adhesion between the pads 42 and improving the convenience of replacing the pads 42.

[0031] In order to control the movement of the second clamp 6 relative to the guide rod 3, sealing rings 51 that fit tightly to the guide rod 3 are fixedly installed on both ends of the hydraulic tube 5 in this embodiment. The interior of the hydraulic tube 5 has a cavity for filling with hydraulic oil. Under the closure of the sealing ring 51, the cavity inside the hydraulic tube 5 is well sealed.

[0032] In this embodiment, the outside of the hydraulic pipe 5 is also connected to an oil nozzle 52 for connecting to an external hydraulic pipeline to control the flow direction of the hydraulic oil. The outside of the guide rod 3 is also fixedly mounted with a piston 53 located inside the hydraulic pipe 5. The piston 53 slides tightly in the cavity of the hydraulic pipe 5 through an external O-ring.

[0033] In a specific implementation, there are two oil nozzles 52 , which are distributed at both ends of the piston 53 . Hydraulic oil can be injected toward one side of the piston 53 through the oil nozzles 52 , thereby forcing the hydraulic pipe 5 to move toward the other side along the guide rod 3 .

[0034] The welding device in this embodiment includes a side plate 7 for connection, a mounting ring 8 rotatably connected to the side plate 7, and a welding machine 9. Both ends of the side plate 7 are integrally connected with an extension ear 72. The extension ear 72 slides relative to the guide rod 3, so that the side plate 7 can slide relative to the guide rod 3 to adjust its position.

[0035] Furthermore, circular rings 71 are fixedly installed on adjacent side surfaces of the two side panels 7, and connecting grooves 10 corresponding to the circular rings 71 are opened on the left and right sides of the mounting ring 8. The circular ring 71 is embedded in the connecting groove 10 and rotates relative to the connecting groove 10, so that after the two side panels 7 clamp the mounting ring 8 in the middle, the mounting ring 8 can rotate relative to the two side panels 7.

[0036] In this embodiment, the welding machine 9 is plugged into the mounting ring 8 and can be adjusted to extend to the length inside the mounting ring 8 to adapt to the welding of stainless steel pipes of different diameters. At the same time, the inside of the mounting ring 8 should have a damping sleeve so that the plug-in adjustment of the welding machine 9 is subject to a certain resistance, so as to facilitate maintaining the adjusted position of the welding machine 9.

[0037] It should be noted that a locking ring 73 is also installed on the outside of the extension ear 72 for locking the side plate 7 relative to the guide rod 3. The locking ring 73 can be used to easily fix the side plate 7. The locking ring 73 can also use a nut to fix the side plate 7 only.

[0038] The working principle of the above embodiment is:

[0039] For the two sections of stainless steel pipes that need to be welded, one section of the stainless steel pipe is passed through the first clamp 4 on one side of the bracket 1 for clamping and fixing, and the other section of the stainless steel pipe is passed through the second clamp 6 on the other side of the bracket 1 for clamping and fixing, and the hydraulic oil pipe is connected to the oil nozzle 52, and the hydraulic oil is controlled to push the hydraulic pipe 5 of the second clamp 6 to force the two sections of stainless steel pipes to approach each other and dock. At this time, the mounting ring 8 and the welding machine 9 are passed between the two sections of stainless steel pipes, and the two side plates 7 are brought close to each other so that the connecting groove 10 outside the mounting ring 8 and the extension ear 72 on the inner side of the side plate 7 are slidably connected to each other, and the installation of the welding machine 9 is completed. The welding machine 9 is used to weld the docking point of the two sections of stainless steel pipes, and the mounting ring 8 can be rotated relative to the two sections of stainless steel pipes to adjust the welding position without the need to clamp the stainless steel pipes again.
