Embodiment 1
[0016] Such as figure 1 with figure 2 As shown, the present invention includes a flange 1 and a shaft sleeve 2, which are connected together by integral molding.
[0017] The structure of the blue plate 1 is: the blue plate 1 is disc-shaped, with Φ144 as the center circle on the side surface, and 12 threaded through holes 3 of M12-M18 with the same diameter are evenly provided, and threaded holes are evenly distributed. It can be connected with other parts by thread.
[0018] The structure of the shaft sleeve 2 is: the main body of the shaft sleeve 2 is a hollow stepped shaft, and the cavity of the shaft sleeve 2 is provided with a first groove 4, a first flange 5, a second flange 6, and a third flange in sequence from left to right. The flange 7 and the second groove 8; the outer circular surface of the shaft sleeve 2 is provided with a third groove 9 near the right side 1 / 3: the right outer circular surface of the shaft sleeve 2 is provided with three evenly distributed ...

The invention discloses an oil cylinder head dedicated to excavators, which comprises a flange plate and a shaft sleeve, and the flange plate and the shaft sleeve are connected together by the method of integral forming. In the structure of the flange plate, the flange plate is shaped like a disk, and the side surface is evenly provided with twelve M12-M18 threaded through holes with the same diameter with Phi 144 as a central circle. In the structure of the shaft sleeve, the body of the shaft sleeve is a hollow stepped shaft, and the cavity of the shaft sleeve is provided with a first groove, a first flange, a second flange, a third flange and a second groove sequentially from the left to the right; the periphery of the shaft sleeve is provided with a third groove at a one-third position close to the right side; the right periphery of the shaft sleeve is provided with three evenly distributed Phi 12 through holes. The design of the oil cylinder head is compact, the structure is reasonable, and with a plurality of step shafts, the oil cylinder head can effectively prevent oil leakage. Since the oil cylinder head is provided with the evenly distributed threaded holes, the oil cylinder head can be connected with other parts through screw threads. The structure of the oil cylinder head is simple, the manufacturing cost is low, and since the method of integral forming is adopted, the service life of the oil cylinder head can be prolonged.
Description
technical field [0001] The invention relates to the field of excavators, in particular to a special oil cylinder head for excavators. Background technique [0002] An excavator, also known as an excavator, is an earth-moving machine that uses a bucket to excavate materials that are higher or lower than the bearing surface, and load them into transport vehicles or unload them to the stockyard. The materials excavated by the excavator are mainly soil, coal, sediment, and pre-loose soil and rock. At present, the design of the hydraulic lever shaft sleeve is unreasonable, the structure is not compact, oil leakage is easy to occur, the service life is short, and it is not suitable for high-efficiency work. Contents of the invention [0003] In order to overcome the deficiencies of the prior art above, the present invention provides an excavator-specific oil cylinder head, and the excavator-specific hydraulic lever coupling shaft sleeve has a simple structure, is convenient ...
