Polishing device capable of guaranteeing blank surface of hydraulic part

Abstract

The invention relates to the technical field of polishing, and discloses a polishing device capable of guaranteeing a hydraulic part blank surface, which comprises a honing head body, a cylindrical mounting body is arranged on the periphery of the honing head body, an oilstone seat is slidably connected in the honing head body and the cylindrical mounting body, honing oilstones are fixed on the outer wall of the oilstone seat, and the honing oilstones are fixed on the outer wall of the oilstone seat. The two ends of the oilstone base are connected with springs in a penetrating mode, and a cone is movably connected into the honing head body. The groove is formed in the outer wall of the cone, the cone shaft drives the cone and the oilstone base to rotate asynchronously through meshing of the gear sleeve and the gear, when the oilstone base rotates to the groove, the oilstone base moves towards the interior of the groove under the action of the elastic force of the spring, honing oilstone is temporarily separated from the inner wall of a workpiece, and honing is completed. The honing oilstone and the inner wall of the workpiece can be flushed, the situation that flushing of the surface of the honing oilstone is affected due to the fact that the honing oilstone is tightly attached to the workpiece is avoided, and scraps attached to the surface of the honing oilstone are reduced.

Description

technical field [0001] The invention relates to the technical field of polishing, in particular to a polishing device for ensuring the rough surface of a hydraulic part. Background technique [0002] Hydraulic parts are all components used in hydraulic systems such as hydraulic pumps, hydraulic motors, hydraulic cylinders, hydraulic valves, and boosters. Hydraulic parts polishing is to polish the wear marks left on the surface of the hydraulic parts after processing, reduce the roughness, and make the surface of the hydraulic parts bright and smooth, which can achieve the effect of mirror surface. [0003] Honing is the polishing of the inner diameter of the hydraulic cylinder, which is usually used to polish the inner diameter of parts such as hydraulic cylinder blocks. The cylindrical honing head has several whetstones (whetstones) attached to the side, which are polished by rotating and reciprocating, and are pressed against the inner surface by the force of the spring, ...

AI Technical Summary

Problems solved by technology

[0005] In view of the deficiencies in the use of the existing polishing device proposed in the background technology, the present invention provides a polishing device that ensures the blank surface of hydraulic parts, which can wash the oil stone inside the workpiece, improve the washing effect of the oil stone surface grinding, The advantage of reducing grinding inside the workpiece solves the problems raised in the background art above
