Problems solved by technology

[0002] The hydraulic cylinder in the horizontal jack is the driving part of the horizontal jack, which has the function of driving the jack up or down, and the pushing piston of the hydraulic cylinder reciprocates in the hydraulic cylinder with the oil pressure in the hydraulic cylinder. It has an oil inlet and an oil outlet, which is convenient for the oil to enter and exit. The oil inlet and the oil outlet are perpendicular to the extension direction of the hydraulic cylinder, so the positions of the oil inlet and the oil outlet are at right angles. When the piston is pushed When the seal passes through the oil inlet or outlet hole, the right angle at the oil hole will cause damage to the seal of the pushing piston. Serious burrs at the oil hole will hinder the normal movement of the pushing piston, and even cause the seal to be stuck at the oil port. If the oil hole is tapped manually, there are defects of inaccurate positioning and low verticality of tapping

Embodiment approach

[0039] An embodiment of the secondary processing technology of the oil hole of a horizontal jack hydraulic cylinder according to the present invention, the specific steps include:

[0040] S1, positioning the oil hole knocking device, such as figure 1 As shown, the oil hole knocking device includes an operating platform 1 and a clamping table 2 placed on the operating platform 1 for clamping the hydraulic cylinder 4. The operating platform 1 has a knocking assembly 3, and the knocking assembly 3 is placed on the hydraulic cylinder. 4 side;

[0041] The clamping table 2 includes a lower clamping body 21 and an upper clamping body 22 hinged to each other. There is a cavity 23 in which the hydraulic cylinder 4 is embedded horizontally between the upper clamping body 22 and the lower clamping body 21. The operating platform 1 has The slide rail 24 that accommodates the horizontal and linear movement of the clamping table 2, the lower clamping body 21 is fixed on the operating pla...

Abstract

The invention relates to a secondary machining process for an oil hole of a hydraulic cylinder of a horizontal jack. The process includes the specific steps that S1, an oil hole knocking device is positioned; S2, the length of the oil hole of the hydraulic cylinder is measured, wherein the length d between the end face of the hydraulic cylinder and the center of the oil hole is measured by a vernier caliper; S3, the hydraulic cylinder is installed and the oil hole is positioned; S4, the length of a fixing rod is positioned and then adjusted to be consistent with d; S5, the oil hole is perpendicularly knocked by a steel ball in a reciprocating mode for 8 s to 10 s; and S6, the oil hole is polished by rubber, wherein a clamping table is moved and the hydraulic cylinder is dismounted, and theoil hole is polished by the rubber dipped with diamond micro-powder. The secondary machining process has the following advantages that the oil hole is knocked so as to be smoother and flatter, scraping damage of a sealing part is avoided, and clamping of the sealing part and normal operation of a pushing piston are guaranteed.
