The machine is used for machining a flange on equipment on site, and the main shaft of the double-support flange machining machine issequentially provided with an inner supporting plate, a knife rest and a shaft sleeve, plurality of screw holes are formed in the outer edge surface of the inner supporting plate, screw rods are arranged in the screw holes, supporting legs are arranged at the outer ends of the screw rods, a rotating arm is arranged on the knife rest, a feeding screw and a feeding motor are arranged on the rotating arm, a feeding screw is arranged on the feeding screw, a sliding knife holder is arranged on the feeding nut, an organic frame is arranged on the shaft sleeve, an outer supporting plate is fixedly arranged on the machine frame, the rotating motor, a plurality of pull rods are uniformly distributed on the periphery of the outer support plate, a pull rod nut is arranged at the outer end of each pull rod, the rotary motor drives the shaft sleeve to rotate, the longitudinal pushing motor is provided with a longitudinal pushing screw, a longitudinal pushing nut on the longitudinal pushing screw is provided with a connecting plate, the connecting plate is fixedly connected with the main shaft, the inner supporting plate is arranged in the flange hole, the pull rod is connected with the flangebolt hole, and therefore the rack is fixed on the flange plate, high-precision machining and repairing can be carried out on the butt joint surface of the flange on site, the repairing difficulty andthe repairing cost are reduced, the repairing efficiency is improved, and the working time is saved.

Description

technical field [0001] The invention relates to a special machine for flange processing, in particular to a double-support flange processing machine. Background technique [0002] Flange is a commonly used connection and sealing structure on various containers, pipelines and other equipment. The butt joint surfaces of existing flanges are usually flat or grooved occlusal surfaces, which meet the sealing requirements, and the precision requirements of the flange butt joint surfaces are relatively high. , but in daily production and use, the situation that the flange is corroded, scratched, and bumped cannot be completely avoided, so it will cause defects such as damage and cracks on the flange butt joint surface. The butt joint surface is repaired. When repairing, the metal material is first filled into the damaged part of the flange butt joint surface by metal welding process, and then the repaired part is manually polished to a flat surface, that is, the repair is completed...

Problems solved by technology

[0002] Flange is a commonly used connection and sealing structure on various containers, pipelines and other equipment. The butt joint surfaces of existing flanges are usually flat or grooved occlusal surfaces, which meet the sealing requirements, and the precision requirements of the flange butt joint surfaces are relatively high. , but in daily production and use, the situation that the flange is corroded, scratched, and bumped cannot be completely avoided, so it will cause defects such as damage and cracks on the flange butt joint surface. The butt joint surface is repaired. When repairing, the metal material is first filled into the damaged part of the flange butt joint surface by metal welding process, and then the repaired part is manually polished to a flat surface, that is, the repair is completed.

However, the precision of the butt joints of flanges on pressure equipment such as pressure vessels and pressure pipes is very high. When repairing, the accuracy of manual grinding is difficult to achieve the precision of lathe processing, which makes manual repair of the joints of flanges difficult and inefficient. , and the processing pass rate is low, the rework rate is high, and the labor cost is high; and the flange is mostly welded with the equipment. If the equipment connected to the flange is disassembled and transported away for machine repair, it is necessary to use hoisting and transportation equipment for transfer , the construction period is longer and the cost is higher; so it is necessary to design an equipment that can machine the flange butt joints on site
