The problem that existing oil cylinder piston bar welding sequence is loaded down with trivial details in order to overcome
, the production cycle is long; The present invention provides a kind of welding method of novel telescopic oil cylinder piston bar; This welding method has not only been simplified the welding sequence of oil cylinder piston bar; And time saving and energy saving, enhance productivity.
the technical solution adopted for the present invention to solve the technical problems is: this novel telescopic oil cylinder piston bar comprises that earrings, the piston body of rod, gripper shoe, little core pipe, big core pipe, baffle ring, bar block up; This novel telescopic oil cylinder piston bar has the middle part piston body of rod in a tubular form; Piston body of rod two ends are respectively equipped with column, and to have earrings and the bar of asphalt channel stifled; In the piston body of rod, be provided with the little core pipe of parallel placement, big core pipe; One end of little core pipe, big core pipe welds with the earrings of the piston body of rod one end is fixing respectively; The other end of little core pipe, big core pipe respectively with the stifled fixing welding of the bar of the piston body of rod other end that is provided with hydraulic fluid port, little core pipe is aimed at connections with being located at the hydraulic fluid port of bar on stifled simultaneously, the middle part of little core pipe, big core pipe is fixed with the gripper shoe that is the right-angled intersection placement respectively and is welded.
The concrete operations step of the welding method of this novel telescopic oil cylinder piston bar is:
2. with an end of little core pipe, big core pipe respectively with earrings on the corresponding grafting of asphalt channel socket; Gripper shoe is installed to the centre position of little core pipe, big core pipe; Again with the other end of little core pipe, big core pipe respectively with the corresponding grafting of asphalt channel socket on bar is stifled, adjust and locate the tram of the axial symmetrical, parallel of each interface;
3. with the fixing welding in the junction of gripper shoe and little core pipe, big core pipe, again with little core pipe, big core pipe respectively with earrings and the stifled fixing welding of splicing position of bar;
4. the workpiece after the welding is carried out the pressure testing operation;
5. an end correspondence of the piston body of rod is packed on the piston body of rod stopping table rank on the earrings; The other end and the stifled end location and installation of bar with the piston body of rod; Again baffle ring is close to the piston rod end of body and installs, the position of adjusting axial symmetry after integral installation finishes is welded fixing then;
6. the workpiece after the welding is carried out the pressure testing operation;
7. last unified cylindrical that earrings, the piston body of rod and bar are blocked up carries out finish turning, correct grinding and chromium plating operation.
the invention has the beneficial effects as follows, this welding method is once welded completion back pressure testing, change next procedure and carry out car-mill-chromium plating operation, and method is simple, makes welding easily, and time saving and energy saving, reduces the operation cycle, enhances productivity.
