Description
Technical field
The present invention relates to a kind of honing machine, specifically refer to honing head.
Background technology
Honing process is a kind of cutting technology with extensive future, it is not only a kind of processing method that can improve surface roughness, and become can remove fast and reliablely must surplus, a kind of semifinishing improving work piece inner surface precision and accurately machined process.Honing does not need special condition that part just can be made to obtain in the manufacturing industry such as accurate size, geometric accuracy, military project and engineering machinery.
Honing process belongs to finished machined, the machining accuracy higher than general machining can be obtained, be characterized in the bonded abrasive tool oilstone using high-quality particulate abrasive to make, particulate can ensure high-caliber machining accuracy, require that abrasive grain, die hardness and tissue keep good uniformity, require the accuracy that die size form trait is higher, and do small cutting to realize each cutting edge and cut efficiently, require that grinding tool and workpiece have larger contact area, therefore finished machined requires good cooling, cooling and chip removal condition.
But in existing vertical honing machine, honing head is when the roughness of work piece inner surface is reduced to minimum level, oilstone on honing head and the contact area between workpiece inner wall reduce, the multiple oilstones on honing head are made to occur idle running phenomenon, before regulating the spacing between workpiece inner wall, oilstone suddenly loses the obstruction dynamics of work piece inner surface upper process thing in the process of running up, and then the rotating speed of oilstone is improved suddenly, being synchronized with the movement between oilstone and honing head body is made to occur error, namely there is relative displacement in both, being connected and fixed between oilstone and honing head is made to occur crackle, cause the rapid drawdown in service life of honing head.
Summary of the invention
The object of the present invention is to provide honing head, conveniently realizing high accuracy polishing to workpiece inner wall, avoid oilstone in use impaired, and then reach the object extending honing head service life.
Object of the present invention is achieved through the following technical solutions:
Honing head, comprise the honing body of inner hollow and multiple cushion block, multiple transitional pore is offered in the both sides of described honing body, the side of cushion block is fixed with adjustment pin, and adjustment pin and transitional pore matched in clearance, at the opposite side of cushion block, holder is installed, holder offers groove, the two side of groove is respectively equipped with blind hole, cross section is that the horizontal part main body of the oilstone of T-shaped is placed in groove and the two ends of its horizontal part are placed in blind hole, leave gap between the vertical portion of oilstone and groove, between described blind hole and oilstone horizontal part, be provided with rubber strip; Described honing body interior is slided and is provided with adjusting rod, described adjusting rod is provided with multiple tapered protrusion, and the movable end of adjustment pin offers the inclined plane matched with the periphery of tapered protrusion.The present invention is directed to deficiency of the prior art, certain improvement is made to existing honing head, after the roughness of work piece inner surface disappears, ensure that the running status between oilstone and base keeps stable to solve, prevent from relative displacement occurring between the two, to realize the object in extension fixture service life, when the present invention works, oilstone is placed in workpiece, drive the honing operation that honing body starts workpiece inner wall to realize oilstone simultaneously, when being reduced to processing criterion when the roughness of workpiece inner wall, spacing now between oilstone and workpiece inner wall increases, namely start to drive the adjusting rod be positioned in the middle part of honing body, adjusting rod moves down until the inclined plane of periphery directly and on adjustment pin movable end of tapered protrusion cooperatively interacts, make adjustment pin radially outward moving along honing body, realize the gap between oilstone and workpiece inner wall, finally realize the meticulous honing of workpiece inner wall,
Wherein, cushion block is provided with fixed block, directly the bottom of oilstone is moved down along the groove on fixed block during installation, and the cross section of oilstone is T-shaped, namely the horizontal end of oilstone moves along the blind hole of groove inner wall, the vertical end of oilstone then moves at the middle part of groove, ensure the stability of oilstone when rotating, before the roughness of the inwall of workpiece disappears and adjusting rod moves down, oilstone can continue to run up because of the disappearance of running resistance under the effect of inertia, and between holder and oilstone, be snap-fit engagement, make the speed of service of speed of service outline lower than oilstone of fixed block, therefore there will be certain relative displacement between the two, the present invention is provided with rubber strip between oilstone horizontal ends and blind hole, by the deformation of rubber strip in running or reply deformation and then slow down the mutual impact between oilstone and holder, to prevent the relative displacement between holder and oilstone, the synchronism that both guarantees run, finally reach and prevent oilstone from damaging, improve the object in oilstone service life.
Further, offer adjustment hole in the both sides of described honing body, and the adjusting nut that has been threaded on the outer wall of honing body, adjusting nut is fixed with pin, and pin runs through adjustment hole and is connected with adjusting rod.In the radiai adjustment process of oilstone, the adjusting nut be threaded connection on honing body can realize the fine setting of adjusting rod, there is abrupt change when preventing tapered protrusion from coordinating with adjustment pin and cause the fluctuation of service of oilstone, honing body offers adjustment hole, adjusting nut is connected with adjusting rod through adjustment hole by pin, therefore only need can realize moving up and down of adjusting rod at rotation adjusting nut.
Further, also comprise the spring be fixed on honing body, and described spring is positioned at adjusting nut bottom.Move up and down in process at adjusting rod, the rotation of adjusting nut is unsuitable too fast, in the bottom of adjusting nut, spring is set, not only can prevent the decline of adjusting nut or the rate of climb too fast and affect the operational efficiency of oilstone, can also pin move to adjustment hole bottom time honing body is produced because of rotation rock elimination, improve further the honing efficiency of oilstone.
Further, the cross section of described rubber strip is circular or oval.As preferably, rubber strip is set to circle or ellipse by the present invention, can ensure when rubber strip is squeezed generation deformation, the space of enough held rubber strip generation deformation is had in blind hole, reduce impulsive force when producing relative motion between holder and oilstone to the full extent, ensure the service life of oilstone.
The present invention compared with prior art, has following advantage and beneficial effect:
1, the present invention is provided with rubber strip between oilstone horizontal ends and blind hole, by the deformation of rubber strip in running or reply deformation and then slow down the mutual impact between oilstone and holder, to prevent the relative displacement between holder and oilstone, the synchronism that both guarantees run, finally reaches the object preventing oilstone damage, improve oilstone service life;
2, the present invention arranges spring in the bottom of adjusting nut, not only can prevent the decline of adjusting nut or the rate of climb too fast and affect the operational efficiency of oilstone, can also pin move to adjustment hole bottom time honing body is produced because of rotation rock elimination, improve further the honing efficiency of oilstone;
3, rubber strip is set to circle or ellipse by the present invention, can ensure when rubber strip is squeezed generation deformation, the space of enough held rubber strip generation deformation is had in blind hole, reduce impulsive force when producing relative motion between holder and oilstone to the full extent, ensure the service life of oilstone.
