It should be noted that, the traditional manufacturing method of the machine barrel is manual tailor welding, and the manufacturing method of the application has the following sequence: assembly welding of the connecting flange, drilling of the drill plate and assembly welding of the machine barrel.

Firstly, assembling and welding a connecting flange;

the flange is composed of 6 angle steels with two different lengths. The flange assembly welding tool is of an assembly type and is formed by assembling a base, a limiting block and a limiting strip through bolts and nuts. The key part is a base assembly which is composed of a positioning block, a positioning strip, a bottom plate and a foot seat into a whole, and the positioning size of the positioning block and the positioning strip is matched with the size of an inner gear of a connecting flange. On the bottom plate, one side in the length direction is provided with a group of round holes, the opposite side is provided with a group of waist-shaped holes, and the centers of the round holes and the waist-shaped holes are positioned in a straight line. One side in the width direction is provided with a group of round holes and a U-shaped opening, the opposite side is provided with a group of waist-shaped holes, and the centers of the waist-shaped holes are positioned in a straight line. Put the work piece angle steel that the unloading is good at the relevant position in order, the vertical plane of angle steel laminates with the vertical plane of locating piece mutually, and stopper 1 installs on width direction round hole one side, and stopper 2 installs in length direction's both sides, and stopper 3 installs on width direction's another side, all plays the tight fixed action of clamp. The installation of locating piece, location strip is all through bolt, nut hookup, stopper 1, stopper 2 and round hole hookup effect: when the workpiece is positioned by the size of the inner gear, the workpiece is positioned by the length. One side in the width direction is positioned, and the other side in the length direction and the width direction is clamped and fixed. When the workpiece is fixed, the connecting flange is welded, and the relative position of the workpiece is not changed in the whole welding process. When the limiting block and the limiting strip are loosened after welding is finished, the flange can be taken down by loosening the flange at the U-shaped opening by using a rubber hammer.

The connecting flange assembly welding tool has the characteristics that: (1) positioning according to the size of an inner gear, and eliminating the blanking size error; (2) positioning, clamping and fixing are carried out at one time, and human factors are eliminated; (3) double positioning ensures not only the size of the inner gear but also the size of the outer shape; (4) not only is convenient to position and clamp, but also is convenient to take down.

Integral die drill for connecting flange

After the connecting flange is welded, a drill plate is used for drilling, the connecting flange is integrated with a guide sleeve, a hole is formed in the base plate and matched with the connecting hole of the connecting flange in size, and the guide sleeve is fixed in the hole of the base plate. The connecting flange and the drill plate are positioned and clamped into a whole, so that the connecting flange can be drilled. Compared with the traditional method (drilling holes on the angle steel and welding to ensure the size of the connecting holes of the connecting flanges), the drill plate and the workpiece are clamped and positioned at one time, so that the consistency and the integrity of the size of the connecting holes of the connecting flanges are ensured, and welding errors are eliminated.

Third, cylinder assembly welding

After the integral die drilling of the connecting flange, the connecting flange is welded on a machine barrel assembly welding tool and is assembled into a whole by a base, a flange positioning tool, a positioning pin, a bolt and a nut. The supporting seat is composed of a bottom plate, a foot seat and a supporting seat, and a positioning hole and a connecting hole are formed in the bottom plate. The quick clamp is characterized in that the quick clamp is formed by integrating a positioning plate, a fixing plate and reinforcing ribs, wherein the positioning plate is provided with a connecting hole and a square hole, the size of the connecting hole is matched with that of a connecting flange, and a plurality of quick clamps are arranged in front of the positioning plate. The fixing plate is provided with a positioning hole and a connecting hole, and the size of the positioning hole and the size of the connecting hole are matched with those of the positioning hole and the connecting hole of the base. The machine barrel is divided into a single body type and a double body type, the invention is explained by taking the double body type as an example, the machine barrel is formed into a whole by a connecting flange and a coaming, a cavity structure with a rectangular section is formed, and the welding phenomenon is not allowed in the cavity. And installing the flange positioning tool on the base, installing the positioning pin in the positioning hole, and installing the bolt and the nut in the connecting hole. After the flange positioning tool is installed, the connecting flange and the enclosing plate are positioned and placed on the tool, the base supports the connecting flange, the bolt is inserted into the positioning hole, and the quick clamp fixes the connecting flange. The machine barrel is subjected to positioning welding and assembly welding after the positioning clamping, and the two sides of the flange positioning tool are positioned through the positioning pins, so that the straightness and the parallelism of the tool are ensured, the parallelism of the flanges connected with the two ends of the machine barrel and the straightness of the machine barrel are ensured, and the welding deformation of the machine barrel is ensured. And after the tack welding is finished, loosening the quick clamp and taking down the machine barrel to perform reinforcement welding on the machine barrel. The barrel can complete 90% of welding work on the tooling, and the rest can be subjected to reinforcement welding after the barrel is removed. The casing of lifting machine comprises standard festival barrel and non-standard festival barrel, when needs the welding non-standard festival, can tear one end flange location frock off, installs again in non-standard festival position.

The characteristics of barrel assembly welding frock: (1) once positioning and clamping are carried out, and human factors are eliminated; (2) the parallelism, the straightness and the welding deformation of the machine barrel can be ensured; (3) the same frock can weld the barrel of two kinds of different length.
