Abstract
While one or several spherical tool heads are made to move on the machined planar or curved surface, low frequency vibration is applied to them so as to form micro pits on the machined surface. The said method has high machining efficiency, e. g., it may produce ten thousands of micro pits in 2-3 min on the inner wall of one workpiece with 93mm inner diameter and 181mm length. The machining equipment is simple in structure, easy to machine, assemble and regulate and low in production cost.
Description
The present invention relates to method of surface finish and device, relate in particular to surface pit machining method and device.
In many friction pairs with relative motion, the friction bore area must generate oil-bearing structure, to store lubricating oil, reduces friction and abrasion, guarantees the life-span of kinematic pair.Usually adopt flat top honing processing as the final manufacturing procedure of bore area, to form overlapping curve plough groove type flat-top oil-bearing structure; Chrome-faced is to carry out contrary electrolysis behind the hard chrome plating to cylinder sleeve bore perhaps to adopt the spongy chromium plating method, and its surface forms netted groove formula oil-bearing structure, again the technical process of honing processing.
Flat top honing and spongy chromium plating method can improve the wearability of friction pair to a certain extent.But because netted groove communicates with one another, the lubricating oil that is stored in the groove will be extruded along groove, and the raising in friction pair life-span is not remarkable.
The purpose of this invention is to provide a kind of simple in structure, be easy to make, surface pit machining method and device that efficient is high.
In order to achieve the above object, the present invention takes following measures:
Surface pit machining method is to use one or more spherical tool heads, and it is relatively moved along processing plane or curved surface, applies low-frequency vibration simultaneously on tool heads, relies on vibratory impulse to form little hole at work surface.The surface micro-pit processing unit (plant) has frame, is provided with motor, knife bar on frame, and motor connects drive through belt pulley and belt, drive eccentric shaft and slide block join, knife bar one end is provided with slideway and joins with slide block, and the knife bar other end is provided with cutter, and knife bar and frame are joined by turning cylinder.
Advantage of the present invention:
(1). little hole is evenly distributed on the bore area, and all little holes are independent mutually, do not connect mutually, and the lubricating oil that is stored in little hole can not be extruded in the friction pair motion process.
(2). pit machining method efficient height.For the workpiece of internal diameter φ 93mm, length 181mm, can in 2～3 minutes, finish ten hundreds of little hole processing.
(3). can replace flat top honing and spongy chromium plating method.(coating is thick 0.05～0.06mm), adopts hard chrome plating to add that pit machining method only needs 2.5 hours to adopt the spongy chromium plating method to need 4 hours approximately.
(4). the conservation of power energy greatly.
(5). significant prolongation the sport life span of friction pair.
(6). little hole processing unit (plant) is simple in structure, is easy to make, assembles and adjusts, and production cost is low.
(7). retrofit of machine tools is simple.Little hole processing on cylindrical work surface can be reequiped realization usually on engine lathe.
Elaborate below in conjunction with accompanying drawing:
Fig. 1 is a surface micro-pit processing unit (plant) structural front view;
Fig. 2 is a surface micro-pit processing unit (plant) structure vertical view.
Surface pit machining method is to use one or more spherical tool heads, and it is relatively moved along processing plane or curved surface, applies low-frequency vibration simultaneously on tool heads, relies on vibratory impulse to form little hole of certain depth at work surface.In order to form clocklike ten hundreds of little holes, parameters such as workpiece rotational frequency, the tool heads amount of feeding, tool heads diameter, vibration frequency, amplitude are coupling rationally.Concerning the thin-wall cylinder casing inwall, form behind little hole hard chrome plating again, according to electroplating principle, still can make electrodeposited coating form pit face, promptly little hole.
The surface micro-pit processing unit (plant) has frame 2, is provided with motor 4, knife bar 1 on frame, and motor connects drive through belt pulley and belt 3, drive eccentric shaft 5 joins with slide block 6, knife bar one end is provided with slideway and joins with slide block, and the knife bar other end is provided with cutter 7, and knife bar and frame are joined by turning cylinder.
