Description

Technical Field

[0001] The utility model relates to the technical field of surfacing welding equipment, in particular to surfacing welding equipment used for nozzle overhaul. Background Art

[0002] Nozzle overhaul refers to the repair or replacement of worn or damaged nozzles. Overlay welding equipment is the tools and machines used for nozzle overhaul. Overlay welding is the process of adding wear-resistant or high-temperature alloy materials to the nozzle surface to provide additional protection and extend service life. Overlay welding machines are usually equipped with gas flame or arc welding systems, which enable operators to accurately add overlay welding materials to the nozzle.

[0003] When the nozzle is welded by the nozzle cladding machine, the nozzle is usually small in size, and a slight movement can cause the welding position to shift. During long-term operation, continuous manual movement may cause fatigue and instability of the worker, which may affect the accuracy and quality of the operation. Utility Model Content

[0004] The utility model aims to provide a cladding device for nozzle overhaul, which has the advantages of being able to adjust the position and angle of the nozzle after the nozzle is fixed, thereby reducing the difficulty of operation for workers and solving the problem of difficulty in operation when workers use cladding equipment to weld the nozzle.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a surfacing device for nozzle overhaul, comprising a fixed plate and a screw sleeve, a fixed frame welded on the top of the fixed plate, a support plate symmetrically welded on the top of the inner top of the fixed frame, two of the support plates are respectively embedded with bearings one, two inner rings of the bearings one are fixedly installed with screws, the screw sleeve is meshed with the screws through screw holes, a hydraulic cylinder one is installed at the bottom of the screw sleeve, a retaining frame is installed at the bottom of the hydraulic cylinder one, bearings two are respectively embedded and installed on both sides of the retaining frame, two inner rings of the bearings two are respectively fixedly installed with fixing rods, two opposite ends of the two fixing rods are respectively installed with hydraulic cylinders two, two opposite ends of the two hydraulic cylinders two are respectively installed with clamps, and a welding machine is installed on the top of the fixed plate lowered by the retaining frame.

[0006] When using a surfacing welding device for nozzle overhaul in the technical solution, a supporting force is provided to the fixing plate through a fixing seat, and the nozzle that needs welding repair is placed between the two clamps. The two hydraulic cylinders push the two clamps to move in relative directions. The two clamps clamp the nozzle and fix it. The screw rod is rotated using a hand wheel, and the screw sleeve moves on the rotating screw rod through a screw hole. The screw sleeve drives the nozzle to move through the hydraulic cylinder and the retaining frame so that the nozzle is aligned with the welding head of the welding machine. The hydraulic cylinder drives the nozzle to descend through the retaining frame. After the nozzle is lowered to a suitable height, the welding machine performs welding repair on the nozzle. The fixing plate is used to rotate the fixing rod. The fixing rod can drive the nozzle to rotate through the hydraulic cylinder and the clamp to adjust the welding position of the nozzle.

[0007] Preferably, a hand wheel is installed at one end of the screw rod away from the fixing frame, and the hand wheel is parallel to the support plate. The screw rod can be rotated by using the hand wheel.

[0008] Preferably, a slider is installed on the top of the screw sleeve, a slide groove is provided on the top of the fixing frame, and the slider and the slide groove are slidably connected. The slider limits the screw sleeve, and when the screw sleeve moves on the screw rod, the slider slides in the slide groove to prevent the screw sleeve from shaking.

[0009] Preferably, the two clamping plates are parallel to each other, and a distance is left between the two clamping plates and the top end of the inner part of the retaining frame. When the two clamping plates rotate, they will not interfere with the retaining frame.

[0010] Preferably, a fixing plate is installed on the fixing rod of the retaining frame which is away from the inner side of the fixing frame. The fixing plate can be used to rotate the fixing rod.

[0011] Preferably, fixing seats are respectively installed at the four corners of the bottom of the fixing plate, and the fixing seats are perpendicular to the bottom of the fixing plate. The fixing seats provide support force for the fixing plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model arranges a screw rod, a screw sleeve and a clamping plate, and the nozzle that needs welding maintenance is placed between the two clamping plates. The two hydraulic cylinders push the two clamping plates to move and clamp the nozzle. The screw rod is rotated by a hand wheel, and the screw sleeve moves on the rotating screw rod through a screw hole. The screw sleeve drives the nozzle to move through the hydraulic cylinder one and the retaining frame, so that the nozzle is aligned with the welding head of the welding machine. The hydraulic cylinder one drives the nozzle to descend through the retaining frame. After the nozzle is descended to a suitable height, the welding machine performs welding maintenance on the nozzle, and the nozzle can be rotated by using a fixing plate to adjust the welding position of the nozzle. After the nozzle is fixed, the position and angle of the nozzle can be adjusted, thereby reducing the difficulty of operation for the staff. BRIEF DESCRIPTION OF THE DRAWINGS
