Abstract
The utility model discloses a machining center lead screw lubrication sealing structure contains lead screw and shell body, the one end setting of lead screw is in the shell body, and the lead screw rotates for the shell body under the effect of motor, being provided with stair structure in the shell body, being provided with metal spacer ring and metal ring between shell body and the lead screw outer wall, the perpendicular tangent plane of spacer ring is the shape of falling L, and is after the centre bore of spacer ring passes the lead screw, fixed by lock nut the spacer ring is in a lead screw step department, hug closely in the spacer ring and set up a ring, the bottom top of ring makes on a shell body inside step the lead screw is located the partial quilt of shell body the spacer ring is sealed with the ring. The utility model discloses the heart lead screw lubrication sealing structure that realizes, effectively avoid the waste oil dirt can enter into the ball screw lubrication sealing structure inside, wash out the lubricating oil on the inside bearing, and long service life.
Description
Technical field
This utility model relates to machining center technical field, particularly relates to a kind of machining center screw mandrel lubrication sealing structure.
Background technology
In the minds of work in-process, the Z axis of machining center is typically assembled on screw mandrel and is driven by servomotor.Servomotor connection wire rod one end, the screw mandrel other end is assembled in z-axis ball screw lubrication sealing structure；Accepted screw mandrel by driven by motor by z-axis ball screw lubrication sealing structure to rotate, thus drive Z axis to move.The quality of ball screw lubrication sealing structure can directly affect the motion of Z axis whether steadily, accurately, without card, also can affect machining accuracy.
Plastics spacer ring generally used by the waterproof and oilproof sealing ring of existing machining center z-axis ball screw lubrication sealing structure, and owing to screw mandrel moves in not stall, plastics spacer ring is easily damaged.After plastics spacer ring damages, the waste oil dirt in the course of processing can enter into inside ball screw lubrication sealing structure, washes out the lubricating oil in internal bearings, causes bearing damage, strengthens and changes and the cost of maintenance, affects machining accuracy.
Summary of the invention
This utility model purport provides one to can be good at stoping greasy dirt to enter inside ball screw lubrication sealing structure for solving the problems referred to above, the highest ball screw lubrication sealing structure service life, reduces the ball screw lubrication sealing structure of replacement and maintenance cost.
For solving above technical problem, this utility model provides a kind of machining center screw mandrel lubrication sealing structure, comprises screw mandrel and shell body, and one end of described screw mandrel is arranged in shell body, and described screw mandrel rotates relative to shell body under the effect of motor；Being provided with ledge structure in described shell body, be provided with metal spacer ring between described shell body and screw mandrel outer wall, the vertical tangent plane of described spacer ring is inverted L-shaped, after the centre bore of described spacer ring passes screw mandrel, locking nut fixes described spacer ring at screw mandrel one step；Described spacer ring inner close fitting arranges a metal ring, and the bottom of described annulus withstands on a step within shell body, and the part making described screw mandrel be positioned at shell body is sealed with annulus by described spacer ring.
Further, described screw mandrel one end connecting shaft bearing structure, in described bearing arrangement is arranged at shell body and it is isolated from the outside by described spacer ring and annulus.
Further, forming a sluice way between described annulus outer wall and shell body, described sluice way extends to outside shell body.
The machining center screw mandrel lubrication sealing structure that this utility model realizes, spacer ring and annulus are metal structure, compare the spacer ring of conventional plastic structure, and service life is more permanent, isolation effect is better.By the insulation blocking ball screw lubrication sealing structure that metal spacer ring and metal ring are dual, effectively prevent greasy dirt from entering ball screw lubrication sealing structure internal damage bearing, the service life of the highest bearing, reduce maintenance and with changing the cost of bearing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is machining center screw mandrel lubrication sealing structure figure.
In accompanying drawing:
1, shell body；2, spacer ring；3 screw mandrels；4, annulus；5, locking nut；6, bearing
Detailed description of the invention
More being apparent to have technical characteristic of the present utility model, purpose and effect, now comparison accompanying drawing describes detailed description of the invention of the present utility model in detail.
As it is shown in figure 1, a kind of machining center screw mandrel lubrication sealing structure, comprising screw mandrel 3 and shell body 1, one end of described screw mandrel 3 is arranged in shell body 1, and in the present embodiment, the lower end of described screw mandrel 3 connects bearing 6 and is arranged in described shell body 1.Described screw mandrel 3 rotates relative to shell body 1 under the effect of motor；Being provided with ledge structure in described shell body 1, be provided with metal spacer ring 2 and metal ring 4 between described shell body 1 and screw mandrel 3 outer wall, the vertical tangent plane of described spacer ring 2 is inverted L-shaped, is used for isolating the greasy dirt from top to bottom flowed along screw mandrel.After the centre bore of described spacer ring 2 passes screw mandrel 3, locking nut 5 fix the described spacer ring 2 step at screw mandrel 3, prevent screw mandrel 3 from departing from bearing 6 in rotary course.
Described spacer ring 2 inner close fitting spacer ring inwall arranges an annulus 4, described annulus 4 is also metal material, the bottom of described annulus 4 withstands on a step within shell body 1, top withstands on spacer ring horizontal component, the connection making described screw mandrel 3 be positioned at shell body 1 has the part of bearing to be sealed with annulus 4 by described spacer ring 2, thus stop greasy dirt to rinse out the lubricant grease on bearing 6 in entering shell body, thus avoid the bearing damage being arranged in shell body.The fixed form of described spacer ring 2 and metal material determine that spacer ring is more stable more resistant to mill, compare the conventional plastic spacer ring life-span longer, and sealing effectiveness is more preferable.
Described shell body 1 is totally enclosed type shell body, can protect whole lubrication sealing structure, forms a sluice way between described annulus outer wall and shell body, and described sluice way extends to outside shell body, allows waste oil flow out.
Described bearing 6 is internal lubricant grease, is used for lubricating bearing 6, it is ensured that bearing will not stuck, the life-span is longer.
Above in conjunction with accompanying drawing, embodiment of the present utility model is described; but this utility model is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematically; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; in the case of without departing from this utility model objective and scope of the claimed protection, it may also be made that a lot of form, within these belong to protection of the present utility model.
