Abstract
The utility model relates to an oil guide block connection structure, which comprises an oil guide block main body, an oil pipe connection structure and a metal die block connection structure. An oil duct is arranged in the oil guide block main body. The oil pipe connection structure and the metal die block connection structure are respectively arranged at both ends of the oil duct. The oil pipe connection structure comprises a ring-shaped bulge. The inner diameter of the ring-shaped bulge is the same with that of the oil duct. The metal die block connection structure is a smooth plane. The smooth plane is provided with a plurality of fastening screw holes. The fastening screw holes are arranged around the oil duct. The fastening screw holes are through holes which pass through an oil duct block main body. The structure is simple and convenient to fix and has a smooth oil line and good sealing performance.
Description
Technical field
The utility model belongs to hydraulic transmission technology field, specifically is a kind of oil-guiding block linkage structure.
Background technique
Hydraulic transmission is used in engineering practice a lot, for example field work engineering machinery such as excavator.Because operating environment is abominable, very big for the influence of the oil circuit in the Hydraulic Power Transmission System, especially the joint between the oil circuit, for example just connect relatively difficulty to the oil circuit the metal module by oil pipe, add the influence of operating environment, oil pipe connects the just easier situation such as leakage of oil that occurs to the oil circuit between the metal module.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of new oil-guiding block linkage structure, concrete technological scheme is as follows:
A kind of oil-guiding block linkage structure comprises oil-guiding block body, oil tube connection structure and metal module linkage structure; Be provided with oil duct in the described oil-guiding block body, oil tube connection structure and metal module linkage structure are located at the two ends of oil duct respectively; Described oil tube connection structure comprises annular protrusion, and the internal diameter of annular protrusion is identical with the internal diameter of described oil duct; Described metal module linkage structure is a smooth flat, is provided with a plurality of fastening screw trip bolts hole on this smooth flat, and each fastening screw trip bolt hole is around the oil duct setting, and the fastening screw trip bolt hole is the through hole that passes the oil duct block body.
The periphery of described annular protrusion is provided with annular groove.
The axial cross section of described annular protrusion is trapezoidal, and trapezoidal upper base is outside oil duct.
The axial cross section of described oil duct is straight line type, " C " type or " S " type.
Described smooth flat is provided with sealing gasket, has on the sealing gasket and the corresponding hole of oil duct and fastening screw trip bolt hole.
Because the degree of finish of the surface of contact of oil duct piece and metal module can be enough high, this structure has improved the sealability of surface of contact greatly; Because the setting of annular protrusion can be bound round on projection oil pipe.This structure fixing easy, oil circuit is unobstructed, good seal performance.
Description of drawings
Fig. 1 and 2 is respectively the schematic representation at two visual angles of this structure embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:
A kind of oil-guiding block linkage structure comprises oil-guiding block body, oil tube connection structure and metal module linkage structure; Be provided with oil duct 1 in the described oil-guiding block body, oil tube connection structure and metal module linkage structure are located at the two ends of oil duct respectively; Described oil tube connection structure comprises annular protrusion 4, and the internal diameter of annular protrusion 4 is identical with the internal diameter of described oil duct 1; Described metal module linkage structure is a smooth flat 3, is provided with a plurality of fastening screw trip bolts hole 2 on this smooth flat 3, and each fastening screw trip bolt hole 2 is provided with around oil duct 1, and fastening screw trip bolt hole 2 is the through holes that pass the oil duct block body.
The periphery of described annular protrusion 4 is provided with annular groove 5.
The axial cross section of described annular protrusion 4 is trapezoidal, and trapezoidal upper base is outside oil duct 1.
The axial cross section of described oil duct is straight line type, " C " type or " S " type.
Described smooth flat 3 is provided with sealing gasket, has the hole corresponding with oil duct 1 and fastening screw trip bolt hole 2 on the sealing gasket.Even it is also passable not add sealing gasket herein,, be enough to make smooth flat closely to be connected with metal module because the sufficiently high words of the smoothness on smooth flat surface add the compressing of fastening screw trip bolt.
Claims (5)
1. an oil-guiding block linkage structure is characterized in that comprising oil-guiding block body, oil tube connection structure and metal module linkage structure; Be provided with oil duct in the described oil-guiding block body, oil tube connection structure and metal module linkage structure are located at the two ends of oil duct respectively; Described oil tube connection structure comprises annular protrusion, and the internal diameter of annular protrusion is identical with the internal diameter of described oil duct; Described metal module linkage structure is a smooth flat, is provided with a plurality of fastening screw trip bolts hole on this smooth flat, and each fastening screw trip bolt hole is around the oil duct setting, and the fastening screw trip bolt hole is the through hole that passes the oil duct block body.
