Abstract
A sector shaped worktable for elbow welding is disclosed, and belongs to the technical field of designing and making of worktable for elbow welding. A sector shaped table is provided on the sector table shaft of the big platform. A chain is provided in the chain fixing tank. A chain limiting roller is provided on the big platform. A speed reducer is provided on the output shaft of the electric motor below the big platform. A chain wheel is provided on the speed reducer. A hydraulic oil cylinder is provided below the oil cylinder fixing base. When the big platform is in a horizontal state, the work piece to be welded is disposed on the sector table. A clamp is used to lock the work piece, i.e. elbow. The hydraulic oil cylinder is then started, and the piston rod pushes the big platform up till to 90 degree. The welding gun is positioned to the welding place to weld. In the mean time, the electric motor is started. The speed reducer drives the chain wheel, and in turn the chain to make the sector shaped table to make an arc movement centering the center of the sector table shaft. The side weld connects fan-shaped mesa limit to move, accomplishes the welding to the circular-arc seam of elbow. The structure is simple, designing is reasonable. The various problems that the processing of manual operation and existing equipment exists have been solved.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of elbow welding bench.
Background technology
In present production reality, a lot of large-size pipe manufacturing enterprises are all in the quality problems of seeking to solve the elbow welding, and are especially for the elbow that uses on the pressure vessel, very high for the requirement of welding quality.Adopt artificial welding to exist inefficiency, labor strength is big, problems such as welding quality instability.And more existing welders and equipment are because on the structural design, volume is big, complex structure.In addition, because the seam of elbow is circular arc, and equipment adapts to the straight line welding more now.The Working position of workpiece is difficult to grasp and control with the corresponding of welding gun in practical operation, so welding quality is difficult to be guaranteed.
Summary of the invention
At above-mentioned situation, the purpose of this utility model provides a kind of workbench of particularly suitable elbow welding.To solve the variety of issue that existing equipment and workman operation exists.
Structure of the present utility model is as shown in drawings: be made of large platform, fan-shaped table top, hydraulic means and transmission device.Front end pars intermedia at large platform has a fan-shaped table top rotating shaft.In fan-shaped table top rotating shaft, have fan-shaped table top.On fan-shaped table top, have workpiece holder.One chain holddown groove is arranged on large platform.In the chain holddown groove, chain is housed.On large platform, have the chain limited roller.On the both sides, rear end of large platform, have large platform upset axle bed.On large platform upset axle bed, have the large platform trip shaft.The large platform trip shaft connects with large platform mutually by connecting plate.On connecting plate, have the large platform bracing frame.One motor is arranged below large platform.On motor output shaft, have reductor.Speed reducer output shaft stretches out the large platform face by the speed reducer output shaft hole on the large platform.One sprocket wheel is arranged on the output shaft of reductor.Sprocket wheel is meshed with chain.Pars intermedia has an oil cylinder holder below large platform.Below the oil cylinder holder, have hydraulic jack.On the both sides of large platform bottom, have back-up block.Motor and hydraulic jack are set in place in underground transmission system case.The utility model is and the supporting use of electric welding machine to be arranged on a side of electric welding machine.Its method of work is: when large platform is in level, welded part being placed on the fan-shaped table top, is that the elbow chucking is fixing with workpiece holder with welded part.Primer fluid compressing cylinder then, piston rod boosts large platform.When 90 ° of large platform upsets were erectility, the large platform support contacted to earth, and makes large platform firmly upright.Welded part is near electric welding machine.Behind the welding gun aligned position, carry out welding processing, simultaneously starter motor.Driving sprocket wheel by reductor drives chain again to make fan-shaped table top is that movement in a curve is done in the center of circle with fan-shaped table top rotating shaft.Side weld connects fan-shaped table top limit and moves, and finishes the welding to the circular-arc seam of elbow.The utility model is owing to have hydraulic means, can make large platform upright and work piece delivered to add work and put.Make the welding of elbow seam become convenient and swift because of having fan-shaped table top.The speed and the quality of welding have been improved.Again because have driving chain and limited roller, eliminated the oscillation phenomenon that produces in the gap that exists because of the chain transmission in the welding process and the workpiece rotation process, guarantee the balance of plant motion, thereby guaranteed the quality of welding.It is simple in structure, and is reasonable in design.It is a kind of desirable workbench that particularly is applicable to the elbow welding.
