Description
Technical field
The utility model relates to for the whole honing stone finishing fixture of honing stone rule cavetto.
Background technology
Honing utilizes to be installed on honing head one or more equally distributed honing stone circumferentially, and honing stone radially presses to workpiece hole wall under tension mechanism effect, drives honing head rotate in workpiece hole and do straight reciprocating motion simultaneously by machine tool chief axis; Or honing head only rotates, workpiece moves back and forth, thus realizes the processing to inner hole of workpiece.The structure of existing honing stone is as shown in Figure 1 and 2: comprise oil stone base 21 and be fixedly arranged on the oilstone bar 20 on oil stone base, the bottom of oil stone base 21 is equipped with inclined-plane 22 and plane 23, plane is connected to the tail end on inclined-plane, inclined-plane is for coordinating with the inclined-plane on honing head, oilstone bar is made up of the composite containing abrasive material, be cemented on oil stone base by bonding or welding manner, at the beginning of honing stone makes, the outer surface of oilstone bar is generally plane, but add man-hour actual, need the outer surface of oilstone bar should be the adaptive cylindroid that coincide with inner hole of workpiece.Although in process, oilstone bar outer surface can be made to be trimmed to cylindroid by the interaction of oilstone bar and workpiece, but general work pieces process surplus is less, the oilstone bar that super hard abrasive is made itself has good wearability, thus desirable finished surface is more difficult to get processing is just interim, the machining accuracy of workpiece cannot ensure, so before new honing stone processing work, must repair it.
At present, the method for trimming of honing stone mainly contains electric spark shaving and cylindricalo grinding rule circle two kinds of methods, and because electric spark shaving method dressing efficiency is lower, therefore general employing cylindricalo grinding carries out rule circle to honing stone.For ensureing the cylindricity of assembling rear oilstone bar with honing head, usually directly utilize honing head as orientation tool clamping oil stone base, using the inclined-plane on oil stone base as benchmark, inclined-plane is made to carry out rule circle near the Double-conical-surface of honing lever in honing head, but because honing head two-end structure can not be directly used in location, can only be positioned by Coupling Shaft, but the precision of advising circle cannot be ensured after switching, so when the oilstone bar after rule circle uses, cannot ensure each oilstone bar all with machined surface good contact, so during each more renew oil stone bar, all need to process the cylindricity of the overall oilstone bar of guarantee after the workpiece of some, cause workpiece waste product many, affect manufacturing schedule.Can not to the problem of oil stone base location in order to solve honing head two ends, Chinese patent CN201613504U discloses " a kind of circle gauging device for honing oilstones ", this rule round belting (i.e. finishing fixture) comprises the apotting spindle that axis extends along the longitudinal direction, apotting spindle Main Function is simulation honing lever, apotting spindle is arranged gradient that time interval arranges respectively with the Double-conical-surface of the slope adaptation on oil stone base, on apotting spindle, guiding movement is arranged with holder housing, on apotting spindle before the two ends of holder housing are installed with, rear locking nut, holder housing offers the radial groove installed for corresponding oil stone base, during use, diameter of a circle residing for each oilstone bar is adjusted to meet corresponding rule circle demand by the adjustment of holder housing and apotting spindle relative position, then prevent each honing stone from deviating from by radial groove by ring spring.Existing this rule round belting Problems existing is: need to arrange the Double-conical-surface with the slope adaptation on oil stone base on apotting spindle, the processing technology of Double-conical-surface and junction thereof is complicated, and precision is difficult to ensure, substantially increases the manufacturing cost of rule round belting; In addition, when adjusting the radial position of each oilstone bar, need could be realized by the relative position of adjustment positioning core axle and holder housing, adjustment process is pretty troublesome, inefficiency, adjustment process is the process that an axial dimension and radial dimension transform simultaneously, and Adjustment precision is difficult to ensure.
