Detailed Description
The technical solution of the present invention is further explained with reference to the accompanying drawings and specific embodiments.
Example one
As shown in fig. 1, the anti-splashing oil port joint welding structure for the hydraulic cylinder of the excavator, which is provided by the utility model, comprises a cylinder body 1 and an oil hole 3 arranged on a cylinder barrel of the cylinder body 1, wherein an oil port 2 to be welded with the cylinder barrel of the cylinder body 1 is arranged on the cylinder body 1 through a connecting structure 4, the oil port 2 and the oil hole 3 are coaxially arranged, and an annular groove 41 which is coaxially arranged with the oil port 2 is arranged on the cylinder barrel of the cylinder body 1; the bottom of the oil port 2 is of an arc structure which is attached to the curved surface of the cylinder barrel of the oil cylinder body 1.
The working principle of the anti-splashing oil port connector welding structure for the hydraulic oil cylinder of the excavator based on the first embodiment is as follows: because the connecting structure 4 is located in the annular groove 41, between the oil port 2 and the cylinder barrel of the oil cylinder body 1, the oil port 2 can be temporarily positioned on the oil cylinder body 1 through the connecting structure 4, so that the oil port 2 and the oil cylinder body 1 cannot be deviated in position during welding.
Example two
As shown in fig. 2a and fig. 2b, compared with the first embodiment, the connection structure 4 in the first embodiment of the present invention includes a plurality of inner recesses 42 disposed in the annular groove 41 around the axial direction of the oil hole 3, a plurality of outer protrusions 43 corresponding to the inner recesses 42 are disposed at the bottom of the oil hole 2, and the outer protrusions 43 extend into the corresponding inner recesses 42; the depth of extension of the concave portion 42 is 1/2 times the thickness of the cylinder tube wall of the cylinder body 1.
In this embodiment, before hydraulic fluid port 2 and the welding of hydro-cylinder main part 1, hydraulic fluid port 2 bottom is provided with a plurality of outer convex parts 43 and inserts in the interior concave part 42 that corresponds in proper order, limiting displacement to hydraulic fluid port 2 through interior concave part 42 and outer convex part 43, when avoiding hydraulic fluid port 2 and the welding of hydro-cylinder main part 1, produce the removal, thereby improve the welding precision, after 4 location through connection structure, weld again, and simultaneously, the extension degree of depth of interior concave part 42 is 1/2 of the cylinder section of thick bamboo wall thickness of hydro-cylinder main part 1, avoid because interior concave part 42 extends deeply, lead to the intensity reduction of hydro-cylinder section of thick bamboo.
