Abstract
The invention discloses the oil cylinder head that a kind of excavator is special, including ring flange and axle sleeve, linked together by the mode of global formation.The structure of blue dish is: blue dish is discoid, encloses on the side surface, be uniformly provided with the tapped through hole of 12 consistent M12-M18 of diameter centered by Φ 144.The structure of axle sleeve is: axle sleeve main body is the Step Shaft of hollow, and axle sleeve inside cavity is from left to right sequentially provided with the first groove, the first flange, the second flange, third lip and the second groove；The outer round surface of axle sleeve is provided with the 3rd groove near the position on right side 1/3: the right side outer round surface of axle sleeve is provided with the through hole of equally distributed three Φ 12.This device is compact to design, rational in infrastructure, is provided with multiple Step Shaft and can effectively prevent leakage of oil.This device is provided with equally distributed screwed hole, it is possible to be connected with other parts by screw thread.This apparatus structure is simple, manufacturing cost economy, adopts the mode of global formation to improve device lifetime.
Description
Technical field
The present invention relates to excavator field, the oil cylinder head that particularly a kind of excavator is special.Background technology
Excavator, also known as excavation machinery, is excavate higher or lower than the material holding machine side with scraper bowl, and loads haulage vehicle or unload the earthmoving machinery to rickyard.The material that excavator excavates is mainly soil, coal, silt and the soil after pre-pine and rock.At present, hydraulic pressure thick stick connecting shaft Analysis of Nested Design is unreasonable, and structure is not compact, it is easy to produce the phenomenon of leakage of oil, and the life-span uses short, is unsuitable for working expeditiously.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides the oil cylinder head that a kind of excavator is special, the hydraulic pressure thick stick connecting shaft set that this excavator is special, simple structure, easy to use and efficiency can be greatly improved.
For solving above-mentioned technical problem the technical solution adopted in the present invention it is: include ring flange and axle sleeve, linked together by the mode of global formation.
Further, the structure of described blue dish is: described blue dish is discoid, encloses on the side surface, be uniformly provided with the tapped through hole of 12 consistent M12-M18 of diameter centered by Φ 144.
Further, the structure of described axle sleeve is: described axle sleeve main body is the Step Shaft of hollow, and described axle sleeve inside cavity is from left to right sequentially provided with the first groove, the first flange, the second flange, third lip and the second groove；The outer round surface of described axle sleeve is provided with the 3rd groove near the position on right side 1/3: the right side outer round surface of described axle sleeve is provided with the through hole of equally distributed three Φ 12.
Further, the concrete annexation of described ring flange and axle sleeve is: described ring flange is coated on by integrally formed mode on the outer round surface in the left side of axle sleeve.
Compared with prior art, the invention has the beneficial effects as follows:
1. this device is compact to design, rational in infrastructure, is provided with multiple Step Shaft and can effectively prevent leakage of oil.
2. this device is provided with equally distributed screwed hole, it is possible to be connected with other parts by screw thread.
3. this apparatus structure is simple, manufacturing cost economy, adopts the mode of global formation to improve device lifetime.
Accompanying drawing explanation
Fig. 1 is the plane view of the present invention.
Fig. 2 is the left view of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
Embodiment 1
As depicted in figs. 1 and 2, the present invention includes ring flange 1 and axle sleeve 2, is linked together by the mode of global formation.
The structure of blue dish 1 is: blue dish 1, for discoid, enclosed centered by Φ 144 on the side surface, is uniformly provided with the tapped through hole 3 of 12 consistent M12-M18 of diameter, is provided with equally distributed screwed hole, it is possible to be connected with other parts by screw thread.
The structure of axle sleeve 2 is: axle sleeve 2 main body is the Step Shaft of hollow, and axle sleeve 2 inside cavity is from left to right sequentially provided with first groove the 4, first flange the 5, second flange 6, third lip 7 and the second groove 8；The outer round surface of axle sleeve 2 is provided with the 3rd groove 9 near the position on right side 1/3: the right side outer round surface of axle sleeve 2 is provided with the through hole of equally distributed three Φ 12, compact to design, rational in infrastructure, is provided with multiple Step Shaft and can effectively prevent leakage of oil.
The concrete annexation of ring flange 1 and axle sleeve 2 is: ring flange 1 is coated on the outer round surface in the left side of axle sleeve 2 by integrally formed mode, adopts the mode of global formation to improve device lifetime.
