Embodiment Construction
[0016] Such as Figure 1-3 As shown, the oil pipe arrangement mechanism of the oil cylinder of the excavator is arranged on the cylinder body 1. This mechanism includes the first oil pipe 2 fixed on one end of the cylinder body 1, and the second oil pipe 3 is fixed on the other end of the cylinder body 1. Its characteristics That is, the first oil pipe 2 and the second oil pipe 3 are both L-shaped, the centerline of the L-shaped long section of the first oil pipe 2 coincides with the centerline of the L-shaped long section of the second oil pipe 3, and the first oil pipe 2 The center line of the L-shaped short section of the second oil pipe 3 coincides with the centerline of the L-shaped short section of the second oil pipe 3, and the L-shaped short section of the first oil pipe 2 and the L-shaped short section of the second oil pipe 3 are arranged symmetrically.
[0017] Specifically, as Figure 1-2 As shown, the cylinder body 1 is provided with a first support pipe clamp 4 ...

The invention belongs to the technical field of mechanical equipment, and relates to an oil pipe arrangement mechanism, in particular to the oil pipe arrangement mechanism of an excavator oil cylinder. The oil pipe arrangement mechanism solves the technical problems of unreasonable design and the like in the prior art. The mechanism is arranged on a cylinder body and comprises a first oil pipe fixed at one end of the cylinder body, a second oil pipe is fixed at the other end of the cylinder body, and the mechanism is characterized in that the first oil pipe and the second oil pipe are L-shaped, a central line of an L shape long section part of the first oil pipe and a central line of an L shape long section part of the second oil pipe are overlapped, a central line of an L shape short section part of the first oil pipe and a central line of an L shape short section part of the second oil pipe are overlapped, and the L shape short section part of the first oil pipe and the L shape shortsection part of the second oil pipe are symmetrically arranged. The mechanism has the advantages that design is reasonable, the structure is simple, installation is convenient, the stress balance ofthe oil cylinder can be kept, and the production efficiency of the oil cylinder can be improved.
Description
technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to an oil pipe arrangement mechanism, in particular to an oil pipe arrangement mechanism for an excavator oil cylinder. Background technique [0002] The hydraulic cylinder is a widely used industrial automation device with many models; the known excavator hydraulic cylinder generally includes a cylinder body, a piston rod assembly, a piston and an oil pipe. As for the distribution of the overall oil pipes of the oil cylinder, the usual practice is that the oil pipes are distributed on both sides of the cylinder block. The manufacturing process of this structure is loaded down with trivial details, and production efficiency is low. [0003] In order to solve the problems existing in the prior art, people have carried out long-term exploration and proposed various solutions. Chinese patent literature discloses an excavator forearm oil cylinder [application number: 200920...
