Abstract
The utility model provides a novel structure for sticking and fixing an oil inlet/outlet of a hydraulic oil cylinder. A process of carrying out butt welding and machining on a cylinder barrel and a connector of the oil inlet/outlet in a previous process is changed into that a ladder hole with a large inside and a small outside of an oil feeding/discharging hole on a cylinder body and a matched ladder-shaped connector of the oil inlet/outlet are machined; in an assembling process, a sealing face of the ladder hole of the oil feeding/discharging hole on the cylinder body and the connector of the oil inlet/outlet are cleanly washed and dried by blowing, a metal bonding agent is uniformly coated; then the connector of the oil inlet/outlet is sleeved in the cylinder barrel from inside to outside and then a nut coated with the bottom coated with the metal bonding agent is used for upward tightening the connector to be locked and sealed with a mechanical sealing line of the cylinder barrel, so that the connector is stuck with the cylinder barrel. The novel process is used for separating functions of bearing sealing and tensile strength and fixing the connector body by a welding line between the connector and the cylinder barrel in the previous process; the sealing is replaced by the sealing line or a sealing face or a bonding agent between the connector body and the cylinder barrel; the tensile strength is borne by parent materials of the cylinder barrel and the connector.
Description
One, technical field:
The present invention relates to the new texture that a kind of hydraulic ram oil inlet and outlet is adhesively fixed.
Two, background technology:
In the process of human industrial civilization, hydrostatic transmission and Controlling System have obtained using widely in the transmission of all kinds of mechanized equipments and control.
In the technology of existing hydrostatic transmission and control, hydraulic ram is exactly at present most widely used a kind of in the power element.Hydraulic ram plays an important role in the development of the mankind's mechanized equipment.
Along with the direction of hydraulic technique towards high precision, high pressure and high-speed cruising develops, the welding distortion of the oil inlet and outlet of hydraulic ram becomes the difficult problem that people must capture.
In addition, along with the China market end in economic high speed expansion epoch, the hydraulic ram manufacturer is in oil cylinder production and management, and short run, many kinds and delivery date lack is becoming normality.In the cylinder barrel production process of hydraulic ram,--technological 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 that improves cylinder barrel simultaneously.They are badly in need of finding the precision work 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 install and fix oil inlet and outlet; Or after receiving order, only need cylinder barrel is cut down by size, just install and fix oil inlet and outlet, need not to carry out stress relieving by annealing technology and just can carry out the fixing new process of accurately machined hydraulic ram oil inlet and outlet bonding.
Three, summary of the invention:
Purpose of the present invention is exactly to develop a kind of cost new texture low, simple and reliable, that can eliminate hydraulic ram oil inlet and outlet welding distortion effectively.
The new texture that hydraulic ram oil inlet and outlet of the present invention is adhesively fixed, be in original technology, must earlier cylinder barrel be docked the welding post-treatment with the oil inlet and outlet joint, the oil inlet and outlet joint of the stairstepping of changing into first interior big outer little shoulder hole with the enterprising outlet-port of cylinder body and matching with it processes, during assembling, earlier the trim of the shoulder hole of the enterprising outlet-port of cylinder body and oil inlet and outlet joint is cleaned up dry up after, coated with metal binding agent equably, again with oil inlet and outlet joint suit from inside to outside in the cylinder barrel, also scribble the nut of metal adhesive with upwards tension of joint with the bottom surface then, after making the mechanical seal line lock sealing of itself and cylinder barrel, it and cylinder barrel are bondd.Novel process will be born sealing, tensile strength and the function of permanent joint body with original technology center tap and the weld seam between cylinder barrel and separate, its sealing is replaced by the potted line between fittings body and cylinder barrel or trim adding additives, tensile strength is then born by the fertile material of cylinder barrel and joint, has been born the function of permanent joint body by the binding agent between nut and nut bottom surface and the cylinder junction surface.Internal stress and the distortion of the welding of joint and cylinder barrel have so just been eliminated.
The present invention is the new texture that a kind of hydraulic ram oil inlet and outlet is adhesively fixed, its structure is combined by cylinder barrel 1, fittings body 2 and nut 3, it is characterized in that: the oilhole on the cylinder barrel 1 is the interior big little shoulder hole of, and the intersecting lens of the shoulder hole on the cylinder barrel 1 is the wedge angle potted line; Form in the intersection area of fittings body 2 ladder cylinders with relief groove has processed a cone, and the intersecting lens of the shoulder hole on this cone and the cylinder barrel 1 is formed a linear sealing pair; The top external diameter of fittings body 2 has screw thread.When assembling, earlier the installation bonding surface on fittings body 2 and nut 3 and the cylinder barrel 1 is cleaned and dried up, be coated with full metal adhesive equably, oil inlet and outlet fittings body 2 suit from inside to outside in the cylinder barrel 1 just again, from the top of fittings body 2 nut 3 covers being installed, turn nut 3, is that supporting surface is with upwards tension of fittings body 2 with the installation groove plane on the cylinder body cylindrical, sealing pair is combined closely, treat to get final product after metal adhesive solidifies.
The present invention also can adopt the structure formation of the conical surface or flat seal.Can between trim, add metal foil pad or sealing member when adopting face seal, also can be on trim the coating soft metal.
Four, description of drawings:
Accompanying drawing 1 is linear sealing structure principle chart of the present invention.
Five, embodiment:
The specific embodiment of the present invention is: earlier with the interior big outer little shoulder hole of cylinder barrel 1 enterprising outlet-port and with it the oil inlet and outlet fittings body 2 of engagement trapezoidal shape process, installation bonding surface on fittings body 2 and nut 3 and the cylinder barrel 1 cleaned dry up, be coated with full metal adhesive equably, again with oil inlet and outlet fittings body 2 suit from inside to outside in the cylinder barrel 1, from the top of fittings body 2 nut 3 covers are installed, turn nut 3, be supporting surface with upwards tension of fittings body 2 with the installation groove plane on cylinder barrel 1 cylindrical, sealing pair is combined closely, treat to get final product after metal adhesive solidifies.
