Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] A butt welding positioning device for a thin-walled cylinder with a head, which includes a pressure plate 1, a pipe sleeve 2, a pull rod 3, a support body 4, a cone 5, an expansion block 6, a copper pad 7, a countersunk screw 10, and a hoop spring 11. Adjusting nut 13, washer 14, lock nut 15.

[0021] See attached Figure 1~5 , the front end of the pull rod 3 has an external thread, and its rear end has a limit step, the rear end of the pull rod 3 is sleeved in the center hole of the cone 5, and the pull rod 3 and the cone 5 are fixed by welding to form a whole.

[0022] The front end of the pipe sleeve 2 has an external thread, and its rear end has a spigot. The rear end of the pipe sleeve 2 is inserted into the edge of the center hole of the support body 4 and connected by welding, so that the pipe sleeve 2 and the support body 4 form a A whole.

Abstract

The invention discloses a butt welding positioning device for a thin-walled cylinder with a seal head, and belongs to the technical field of process equipment. The device is mainly technically characterized by comprising a pressing plate, a pipe sleeve, a pull rod, a support body, a cone, a bulging block, a copper cushion block, a countersunk screw, a band spring, an adjusting nut, a gasket and a locking nut, wherein the pressing plate is adjusted by the adjusting nut to position a workpiece; the cone is pulled by the pull rod to jack and bulge the three-flap bulging block; the bulging block centers, bulges and clamps the workpiece to be welded; the taper of the inner wall of the bulging block is the same as that of the external surface of the cone; and a radial annular groove is formed on the surface of the copper cushion block. The assembly positioning problem of the thin-walled cylinder with the seal head and a thin-walled hollow cylinder during butt welding can be effectively solved, welding deformation is effectively reduced, and the device has the advantages that: the device has a simple structure, is convenient to assemble and disassemble and is operated and used reliably.

Description

technical field [0001] The invention relates to a butt welding positioning device for a thin-walled cylindrical body with a head, which belongs to the technical field of process equipment, and is mainly suitable for coaxial positioning during the butt welding of a thin-walled cylindrical body with a head and a thin-walled hollow cylindrical body. Background technique [0002] When the thin-walled hollow cylinder is butt welded, due to the thin wall thickness of the cylinder, welding deformation and welding cracks are prone to occur, resulting in unqualified assembly accuracy and even product scrapping. In the background technology, in the butt welding of thin-walled hollow cylinders, since the two thin-walled cylinders to be butt-welded are hollow cylinders, a special long mandrel bulging and centering fixture is generally used in China to clamp the two welded parts coaxially. Tight welding, which can effectively prevent welding cracks and reduce welding deformation. Howeve...
