Abstract
The utility model discloses a numerical control machine tool Z axis screw rod sealed combination structure which comprises a screw rod, a tail end base and a sealing device oil seal for the screw rod and the tail end base. The numerical control machine tool Z axis screw rod sealed combination structure is characterized by further comprising a labyrinth ring and an oil hole, the labyrinth ring is arranged on the outer portion of the oil seal, the labyrinth ring and the screw rod are fixed as a whole, and the oil hole is formed in the connection position of the top of the labyrinth ring and the top end of the tail end base. The top of the labyrinth ring is a bent hook, and a groove used for accommodating the bent hook is formed at the top end of the tail end base. The labyrinth ring is bound with the screw rod to form a whole. The oil seal is located at the bent hook position of the labyrinth ring and located above an undersurface of the groove. The labyrinth ring is adopted for sealing for the sealing device oil seal in the screw rod combination structure, the labyrinth ring and the screw rod rotate simultaneously and are bound together, oil does not inflow from between the labyrinth ring and the screw rod, the oil flows away from the position of the oil hole, the sealing structure reduces the friction between the oil seal and the screw rod, the service life of the oil seal and the screw rod is prolonged, and the sealing precision of the screw rod combination structure is also improved.
Description
Technical field
The utility model relates to a kind of numerical control machine tool Z axle screw rod seal combination structure.
Background technique
In traditional numerical control machine tool Z axle screw combinations, the seal arrangement of motor seat, tail end seat and screw rod is oil sealing commonly used, when this seal arrangement rotated at a high speed at screw rod, oil sealing separated with screw rod, impossible positive confinement between oil sealing and the screw rod, oil will stay between oil sealing and screw rod into the tail end seat like this, and separate between screw rod and the oil sealing, when screw rod rotates at a high speed, between oil sealing and the screw rod friction is arranged, influence the working life of tail end seat and screw rod, sealed precision is not high.
The model utility content
Technical problem to be solved in the utility model provides a kind of numerical control machine tool Z axle screw rod seal combination structure, has solved the problems referred to above.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of numerical control machine tool Z axle screw rod seal combination structure, the seal arrangement oil sealing that comprises screw rod, tail end seat and screw rod and tail end seat, it is characterized in that: also comprise labyrinth ring and oilhole, described oil sealing outside is provided with labyrinth ring, labyrinth ring and screw rod are fixed as one, and labyrinth ring top and joint, tail end seat top form oilhole.
Described labyrinth ring top is crotch, and tail end seat top is provided with the groove of placing this crotch.
The bonding formation one of described labyrinth ring and screw rod.
Described oil sealing is positioned at the crotch position of labyrinth ring, and is positioned on the bottom surface of groove.
Of the present utility model have a following beneficial effect:
The utility model is used the seal arrangement oil sealing in the screw combinations structure instead labyrinth ring and is sealed, labyrinth ring rotates with screw rod, be bonded together, oil can be from not flowing between the two, but flow away from oilhole, the sealing structure decrease friction between oil sealing and the screw rod, improved both working life, also improved the sealed precision of screw combinations structure.
