The two ends end face of described removable many steps straight line mandrel all has spacing hole, its removable many steps straight line mandrel has been bolted positioning pressuring plate, bolt runs through the spacing hole of positioning pressuring plate and removable many steps straight line mandrel successively, and its positioning pressuring plate is connected with porous terminal plate.
The axis of described removable many steps straight line mandrel and the dead in line of concentric axle sleeve.
There is the gap between described removable many steps straight line mandrel and the locating hole.
The clearance distance of described removable many steps straight line mandrel and locating hole is 0.05 mm～0.08mm.
Of the present invention mainly is that the porous terminal plate in the electrical penetration cylinder assembly is located before the assembly welding carrying out, the axiality of the conductor assembly installing hole at assurance two ends is higher, after porous terminal plate is accurately located, can make the welding deformation of follow-up assembly welding be decreased to controlled degree, and then greatly reduce the manufacturing cost of electrical penetration.
The utility model is comprised of bolt, positioning pressuring plate, concentric axle sleeve, removable many steps straight line mandrel, porous terminal plate.During use, the two ends with removable many steps straight line mandrel are arranged in locating hole corresponding to porous terminal plate first, and removable many steps straight line mandrel is installed on the porous terminal plate; Realize being connected of porous terminal plates and removable many steps straight line mandrel with concentric axle sleeve 3 again, realize feeling relieved by the axiality parameter of controlling concentric inner hole of shaft sleeve and cylindrical; Pass positioning pressuring plate with hexagonal bolt at last, in the spacing hole with the removable many steps straight line of bolt precession end face of mandrel, connect the axial location that realizes each part of cylinder assembly by screwing bolt so that fixation clip pushes with the concentric shafts cover.According to the weld seam size, under the prerequisite that the axiality that guarantees two stomidiums requires, leave the gap of 0.05～0.08mm between removable many steps straight line mandrel and the locating hole, can make things convenient for the postwelding dismounting.
Removable many steps straight line mandrel is designed with enough intensity and precision, can effectively guarantee the concentric requirement in each hole and reduce welding deformation.
The utility model positioner uses when can be used as electrical penetration cylinder assembly assembly welding, uses when also can be used as the equipment assembly welding of similar structures.
Positioning accuracy is high, has guaranteed the axiality requirement of the conductor assembly installing hole at two ends; Positioning intensity is good, makes welding deformation be decreased to controlled degree; Convenient disassembly; Improve production efficiency, greatly reduced the manufacturing cost of electrical penetration.
The utility model has the advantage of: the utility model has been realized good each part of first fine finishining, and the process route of assembly welding adopts positioner again, and positioning accuracy is high, has guaranteed the axiality requirement of the conductor assembly installing hole at two ends; Positioning intensity is good, makes welding deformation be decreased to controlled degree; Convenient disassembly; Improve production efficiency, greatly reduced the manufacturing cost of electrical penetration.
