Description
Affiliated technical field
The utility model relates to field of machining, especially a kind of novel cylindrical honing head of honing emery stick centering feeding.
Background technology
The cylindrical honing is a kind of the excircle of workpiece cylinder to be carried out precision machined process; Generally be that several emery sticks on the honing head surround and are pressed on the external cylindrical surface simultaneously; The workpiece rotation, the honing head straight reciprocating motion, emery stick carries out grinding and polishing to surface of the work.Existing cylindrical honing head; The feed motion that each emery stick is pressed to surface of the work generally is not synchronized with the movement; The surface that can not guarantee each emery stick is on the circumference of a fixed axis all the time; Make this cylindrical honing head can only reduce the roughness of surface of the work, can not revise the deviation from cylindrical form of workpiece.For the have relatively high expectations cylindrical honing processing of workpiece of cylindricity, be necessary to develop the feeding of can feeling relieved synchronously of each emery stick, the surface that guarantees each emery stick is in the novel cylindrical honing head on the circumference of a fixed axis all the time.
Summary of the invention
The purpose of the utility model provides a kind of cylindrical honing head of new structure type, reaches the feeding of can feeling relieved synchronously of each emery stick, guarantees that the surface of each emery stick is on the circumference of a fixed axis all the time.
For achieving this end; The technical scheme that the utility model is taked is following: this centering feeding cylindrical honing head mainly is made up of hollow piston rod oil cylinder, inclined-plane annulus, emery stick frame, positioning disk; It is characterized in that: one pair of main body that goes out rod oil cylinder as honing head, fairlead all is equipped with at the cylinder tube two ends; The piston rod center is a cylindrical hole, is fixed with two annulus in the cylindrical hole, and an end face of each annulus is a taper seat; The outside of two fairleads all is fixed with positioning disk, and the positioning disk center is a circular hole, its circular hole of positioning disk upper edge some rectangular channels are radially arranged, each rectangular channel on the positioning disk of both sides is relative one by one along the axis direction of piston rod center cylindrical hole; An emery stick frame is installed in every pair of rectangular channel on the positioning disk of both sides sliding fit; Fixing emery stick on each emery stick frame; Two grooves are arranged on each emery stick frame, and face of this groove is the inclined-plane, the inclined-plane of two grooves on each emery stick frame respectively with the piston rod centre bore in the taper seat sliding-contact of two annulus; Respectively there is a square cotter at two ends on each emery stick frame, and the part that two square cotters stretch out from emery stick frame two sides is close to the outside at two positioning disks respectively; There is an extension spring in the outside of two positioning disks corresponding to each emery stick frame, and an end of this spring is fixed on the positioning disk, and the other end is fixed on the emery stick frame.Piston rod center cylindrical hole, annulus, positioning disk center hole three's axis of rotation overlaps.The gradient on each emery stick frame groove inclined-plane is identical, and identical with the gradient of annulus taper seat.Each emery stick is towards the one side of positioning disk center hole axis, and is all tangent with a face of cylinder that with positioning disk center hole axis of rotation is axis.The direction of pull of each extension spring is to make emery stick frame groove inclined-plane be close to the annulus taper seat.
During this centering feeding cylindrical honing head work, processed cylindrical work passes from the positioning disk center hole, and the axis of rotation of workpiece overlaps with positioning disk center hole axis of rotation.Twoly go out hydraulic fluid port oil-feed of rod oil cylinder, promote piston rod and move forward vertically, two annulus that are fixed in the piston rod cylindrical hole also move forward thereupon; The inclined-plane of each emery stick frame groove of taper seat extruding of annulus; Because the square cotter on each emery stick frame is close in the positioning disk outside, makes each emery stick frame not move vertically, can only be under the radial component between the inclined-plane promotes; In the radially rectangular channel of positioning disk; Circular hole axis of rotation direction is done the radial feed motion to guiding disk center, and the emery stick on it is pressed on the excircle of workpiece cylinder, at this moment just can carry out honing and process.Because the initial face of cylinder that each emery stick working face forms is concentric with workpiece; And the gradient on each emery stick frame groove inclined-plane is identical with the gradient of annulus taper seat; The radial feeds of each emery stick frame are identical all the time; Make that each emery stick working face surrounds the cylinder cutting face of a fixed center all the time in the honing process, thereby make the honing processing of adopting this honing head not only can reduce the surface roughness of workpiece, can also reduce the deviation from cylindrical form of workpiece.After hone processing course finishes, two another hydraulic fluid port oil-feeds that go out rod oil cylinder, piston rod switching-over; Return backward vertically; Two annulus that are fixed in the piston rod cylindrical hole are also retreated thereupon, and each emery stick frame outwards moves in the radially rectangular channel at positioning disk under the tension of extension spring, and emery stick breaks away from surface of the work; Workpiece is extracted out from the positioning disk center hole, has accomplished honing processing.
The beneficial effect of the utility model mainly is; In hone processing course; The feeding of feeling relieved synchronously all the time of each emery stick; The working surface that guarantees each emery stick is in the workpiece axis of rotation to be on the circumference of axis, not only can to reduce the surface roughness of workpiece, can also reduce the deviation from cylindrical form of workpiece all the time.Because feed mechanism is in hollow piston bar inside, make the radial dimension of honing head greatly reduce simultaneously, profile is succinctly attractive in appearance.
