Hydraulic dual-feed honing head device

Abstract

The invention relates to a hydraulic dual-feed honing head which comprises a two-stage telescoping hydraulic cylinder and a honing head body, wherein the outer circumference surface of the honing head body is provided with a coarse honing emery stick seat and a microhoning emery stick seat along the circumferential direction; the two-stage telescoping hydraulic cylinder comprises a first piston rod and a second piston rod; the first piston rod is connected with a first push cone; the second piston rod is connected with a second top-chord inverted triangle mesh; the first top-chord inverted triangle mesh cooperates with the coarse honing emery stick seat; the second top-chord inverted triangle mesh cooperates with the microhoning emery stick seat; when the first top-chord inverted triangle mesh moves forwards, the coarse honing emery stick seat is driven to protrude outwards along the radial direction, thereby carrying out coarse honing; and when the second top-chord inverted triangle mesh moves towards, the microhoning emery stick seat is driven to protrude outwards, thereby carrying out microhoning.

Description

technical field [0001] The invention relates to honing processing equipment, in particular to a hydraulic double-feed honing head device. Background technique [0002] Honing is a process of finishing the finished surface with a honing stick inlaid on the honing head. It mainly processes various cylindrical holes with a diameter of 5-500 mm or even larger, and the ratio of the hole depth to the hole diameter can reach 10. or larger. Under certain conditions, it can also process flat surfaces, outer circular surfaces, spherical surfaces, tooth surfaces, etc. The dimensional accuracy of the hole after honing is IT4~7, and the surface roughness can reach Ra0.04~0.32 microns. For example, for the honing process of some inner holes, it is necessary to grind the inner surface of the deep groove texture with a honing stick with a coarser grain size, and then use a honing stick with a finer grain size to grind off the peaks on the surface of the deep groove texture, so as to achie...

Problems solved by technology

Since the honing head has only one kind of honing stick, if this kind of honing head is used to perform rough honing and fine honing on the same surface, it is necessary to use the rough honing head for rough honing first, and then replace the rough honing head with a fine honing head or replace it directly. A honing machine with a fine honing head performs fine honing. Due to the replacement of the honing head, various parameters such as the initial position of the honing and the feed rate have changed, resulting in a deterioration of the accuracy of the honing process. High process cost and low work efficiency
