Force-transferring intermediate structure

Abstract

The invention discloses a force-transferring intermediate structure. The force-transferring intermediate structure comprises a shell, an intermediate rod, a push rod and a piston rod. The push rod isarranged at one end of the shell. The intermediate rod is arranged in the push rod. One end of the intermediate rod stretches into the shell to be connected with a thrust bearing, and the other end ofthe intermediate rod stretches out of the push rod and is convex. The thrust bearing is arranged in the shell in a sleeved mode through a bearing seat. The piston rod is arranged at the other end ofthe shell. A stroke limiting block is arranged on the intermediate rod. The force-transferring intermediate structure is simple; the stroke limiting block is arranged on the intermediate rod in a sleeving mode and has a good limiting effect on the stroke of the mechanism, so that the mechanism is unlikely to get stuck in the force transferring process, the transferring stability of the whole mechanism is ensured, the working efficiency is greatly improved, the service life is remarkably improved, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of precision machining machinery, in particular to a force transmission intermediate structure. Background technique [0002] The force transmission intermediate device, the driving force of the hydraulic cylinder should be applied to one end of the tugboat shaft to balance the axial force on the tugboat, so that it can reach a state of force balance. If the driving force of the hydraulic cylinder cannot act on the tugboat shaft On the axis, then when the thrust is applied to the tugboat shaft, a moment will be given to the tugboat shaft, which will not only reduce the accuracy of the measurement results, but may also damage the supporting structure when the thrust is large, so the force transmission intermediate device The function is to guide the push rod so that the thrust of the hydraulic cylinder is applied to the shaft end of the tugboat shaft. However, the traditional force transmission intermediate d...

[0002] The force transmission intermediate device, the driving force of the hydraulic cylinder should be applied to one end of the tugboat shaft to balance the axial force on the tugboat, so that it can reach a state of force balance. If the driving force of the hydraulic cylinder cannot act on the tugboat shaft On the axis, then when the thrust is applied to the tugboat shaft, a moment will be given to the tugboat shaft, which will not only reduce the accuracy of the measurement results, but may also damage the supporting structure when the thrust is large, so the force transmission intermediate device The function is to guide the push rod so that the thrust of the hydraulic cylinder is applied to the shaft end of the tugboat shaft. However, the traditional force transmission intermediate device generally has a complicated structure and is prone to jamming, which cannot meet the needs of modern industrial production.
