Double-station connecting rod hole milling and pressing device and hydraulic system thereof

Abstract

The invention discloses a double-station connecting rod hole milling and pressing device and a hydraulic system thereof. The device comprises a frame and an inclined surface slide rod, wherein a T-shaped pressure plate is arranged in the middle of the frame; a positioning block 1 and a positioning block 2 are symmetrically arranged at the upper side of the frame; a V-shaped push head 1 and a V-shaped push head 2 are symmetrically mounted at the two ends of the upper side of the frame; a roller frame is fixed and mounted at the lower end of the T-shaped pressure plate; a roller is rotationally mounted on the roller frame; the end of the inclined surface slide rod is fixedly connected with the end of a piston rod of a hydraulic cylinder; a rodless cavity and a rod cavity of the hydraulic cylinder are respectively communicated with a first working port and a second working port of a reversing valve; a third working port of the reversing valve is communicated with an oil tank; and a fourth working port of the reversing valve is communicated with an oil outlet of a hydraulic pump. The device has the characteristics of reasonable design, high processing precision, capability of performing double-station clamping by one time, high production efficiency, simplicity and convenience for operation, high automation degree and low labor intensity.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a double-station connecting rod hole milling and pressing device and a hydraulic system thereof. Background technique [0002] Such as figure 1 and figure 2 The processing procedure of the connecting rod parts shown is generally to process the large end hole first, and after the large end hole is processed by the boring machine, the small end hole is processed based on the large end hole and its inner surface, so as to ensure the dimensional accuracy of the two holes and verticality requirements. Due to the large processing batch of this type of parts, if the large end holes and small end holes are all processed by the boring machine, the processing time of the boring machine will be longer and the processing pressure of the boring machine will be high. In addition, the commonly used clamping devices for this type of parts are generally single-station, that is, on...

AI Technical Summary

Problems solved by technology

Due to the large processing batch of this type of parts, if the large end holes and small end holes are all processed by the boring machine, the processing time of the boring machine will be longer and the processing pressure of the boring machine will be high.

In addition, the commonly used clamping devices for this type of parts are generally single-station, that is, the clamping can only complete the clamping of one workpiece at a time, so it has low clamping efficiency, long processing preparation time, and high labor intensity. and other shortcomings
