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
[0038] 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:
[0039] 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;
[0040] The clamping table 2 includes a lower clamping body 22 and an upper clamping body 21 hinged to each other. There is a cavity 23 in which the hydraulic cylinder 4 is embedded horizontally between the upper clamping body 21 and the lower clamping body 22. 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 22 is fixed on the operating pla...

The invention relates to a secondary processing technology for the oil hole of a hydraulic cylinder of a horizontal jack. The specific steps include: S1, positioning the oil hole knocking device; S2, measuring the length of the oil hole of the hydraulic cylinder, and measuring the distance between the end surface of the hydraulic cylinder with a vernier caliper The length d at the center of the oil hole; S3, install the hydraulic cylinder and position the oil hole; S4, locate the length of the fixed rod, adjust the length of the fixed rod to make it consistent with d; S5, strike the oil hole vertically with a steel ball, The knocking time is 8s‑10s; S6, rubber polishing oil hole, move the clamping table and disassemble the hydraulic cylinder, and polish the oil hole with diamond powder on the rubber. The invention has the following advantages: the oil hole is smoother and smoother by knocking the oil hole; The locking of the parts and the normal operation of the push piston.
