Abstract
Disclosed is a novel laser welding structure of a connector of an oil inlet-outlet opening of a hydraulic oil cylinder. According to the novel laser welding structure of the connector of the oil inlet-outlet opening of the hydraulic oil cylinder, firstly a threaded hole and a flat mounting surface on the cylinder barrel body and a stair-stepping oil inlet-outlet opening connector body matched with the threaded hole and the flat mounting surface are processed, a flange with a diameter larger than the diameter of threads is arranged on the connector body close to the threaded end of the connector body. During assembling, a user forcefully screws the connector body up downwards to enable the flange face of the connector body to be tightly adhered to the flat mounting surface of the cylinder barrel body, and then welds well the cylinder barrel body and the flange connecting flat surface of the connector body. According to the novel laser welding structure of the connector of the oil inlet-outlet opening of the hydraulic oil cylinder, the functions of sealing, bearing tensile strength and fixing the connector body, which welding seams between the connector body and the cylinder barrel body undertake, in an original process are separated, only the functions of sealing and fixing the connector body are reserved, and a threaded connecting pair between the connector body and the cylinder barrel body bears the tensile strength, so that the internal stress and the deformation of the welding of the connector body and the cylinder barrel body are reduced.
Description
One, technical field:
The present invention relates to a kind of laser weld new construction of hydraulic jack oil inlet and outlet joint.
Two, background technology:
In the process of human industrial civilization, hydraulic drive and control system have obtained using widely in the transmission of all kinds of mechanized equipments and control.
In the technology of existing hydraulic drive and control, hydraulic jack is exactly at present most widely used a kind of in the executive component.All be one of its indispensable element in each hydraulic drive and control system or with hydraulic jack in the hydraulicdriven equipment almost.Hydraulic jack plays an important role in the development of the mankind's mechanized equipment.
Along with hydraulic technique towards high accuracy, high pressure and high-speed cruising direction develop, the welding deformation of the oil inlet and outlet of hydraulic jack becomes the difficult problem that people must capture.
In addition, along with the China market end in economic high speed expansion epoch, the hydraulic jack manufacturer is in oil cylinder production and management, and small lot, many kinds and delivery date lack is becoming normality.In the cylinder barrel production process of hydraulic jack,--technical process of welding oil inlet and outlet--stress relieving by annealing---reprocessing is oversize, is difficult to satisfy actual demand in former the sort of blanking.Unfavorable for the productivity ratio that improves cylinder barrel simultaneously.They are badly in need of finding the fine finishining in enormous quantities of a kind of cylinder barrel same specification standby, after receiving order, only need cylinder barrel is cut down by size, just can weld oil inlet and outlet; Or after receiving order, only need cylinder barrel is cut down by size, just weld oil inlet and outlet, need not to carry out the new process that stress relieving by annealing technology just can be carried out accurately machined minimizing hydraulic jack oil inlet and outlet welding deformation.
Three, summary of the invention:
Purpose of the present invention is exactly to develop a kind of cost joint new construction low, simple and reliable, that can reduce hydraulic jack oil inlet and outlet welding deformation effectively.
The laser weld new construction of a kind of hydraulic jack oil inlet and outlet joint of the present invention, the oil inlet and outlet fittings body that is the stairstepping that matches with the screwed hole on the cylinder barrel and mounting plane with this screwed hole and mounting plane earlier processes, and this fittings body has a diameter greater than the flange of the diameter of thread at it by the end of thread.During assembling, firmly fittings body is tightened downwards, make fit tightly by the mounting plane on flange face and the cylinder barrel after, with laser weld the flange of cylinder barrel and fittings body is connected face bonding again and connects.
The present invention will bear sealing, hot strength and the function of anchor tip body with original technology center tap body and the weld seam between cylinder barrel and separate, and only having kept the function of sealing and anchor tip body, hot strength is then born with the pair that is threaded between cylinder body by fittings body.So the requirement of butt welded seam has just reduced widely, adds the employing laser welding process, weld seam to dissolve layer thinner, thereby reduced internal stress and distortion that fittings body and cylinder barrel weld.
The oil inlet and outlet fittings body 2 of the stairstepping that structure of the present invention matches by the screwed hole on the cylinder barrel 1 and mounting plane with this screwed hole and mounting plane combines, and fittings body 2 has a diameter greater than the flange of the diameter of thread at it by the end of thread.It is characterized in that: the flange lower plane of the oil inlet and outlet fittings body 2 of the stairstepping that matches with the screwed hole on the cylinder barrel 1 and mounting plane with this screwed hole and mounting plane is formed the laser weld faying face, and cylinder barrel 1 is the installation auxiliary connection of port connection with the connecting thread pair of fittings body 2.
The present invention also can adopt screwed hole and the flange lower plane of mounting plane and fittings body 2 between be coated with metal adhesive and seal and anchor tip body 2.
Further, the present invention can also add the version of spot welding between the flange cylindrical of cylinder barrel 1 and fittings body 2.
Further, can also between the flange of cylinder barrel 1 and fittings body 2, adopt and get out several apertures at flange face, in these several apertures, add the version of spot welding again.So just more be conducive to reduce welding deformation.
Four, description of drawings:
Accompanying drawing 1 is structure chart of the present invention.
Five, the specific embodiment:
The specific embodiment of the present invention is: earlier the oil inlet and outlet fittings body of the stairstepping that matches with the screwed hole on the cylinder barrel and mounting plane with this screwed hole and mounting plane processes, and this fittings body has a diameter greater than the flange of the diameter of thread at it by the end of thread.During assembling, firmly fittings body is tightened downwards, make fit tightly by the mounting plane on flange face and the cylinder barrel after, with laser weld the face bonding that is fitted and connected between cylinder barrel 1 and the fittings body 2 is connected again.
