Abstract
The utility model discloses a nut direct-driven numerical control feeding device. A screw nut is arranged in a center hole inside a motor rotor; the screw nut is matched and connected with a screw rod body; both ends of the screw rod body are directly and axially fixed on a fixed part of a machine tool; and the motor rotor is connected with an encoder by a synchronous belt transmission device. The nut direct-driven numerical control feeding device has a simple structure and high positioning accuracy and repeated positioning accuracy and is reliable to use.
Description
Technical field
The utility model belongs to numerical control Metal Cutting Machine Tool field, and especially a kind of nut of Digit Control Machine Tool directly drives the numerical control feeding device.
Background technology
High speed development along with China's machinery manufacturing industry; Demand to Digit Control Machine Tool is increasing; How providing that a kind of simple for structure, positioning accuracy and repetitive positioning accuracy are high, service-strong Digit Control Machine Tool feed arrangement, is the problem of user and manufacturing enterprise's common concern.At present, the feed arrangement that Digit Control Machine Tool is used, precision is on the low side, can not well satisfy the requirement of user's high accuracy, high reliability.
Summary of the invention
The purpose of the utility model is: provide that a kind of simple for structure, positioning accuracy and repetitive positioning accuracy are high, the service-strong nut directly drives the numerical control feeding device.
The technical scheme of the utility model is: comprise motor stator, rotor, motor cabinet; Motor stator is fixed in the motor cabinet; Motor cabinet is installed on the lathe moving-member, in the centre bore of rotor inside feed screw nut is housed, and feed screw nut and leading screw body are connected; The two ends of leading screw body directly are axially fixed on the fixture of lathe, and rotor is connected with encoder through synchronous belt transmission device.
The beneficial effect of the utility model is: because the used feed screw nut of feed screw is installed in the centre bore of rotor, be fastened on the end face of rotor, directly driven by servomotor.The two ends of leading screw body then directly are axially fixed on the fixture of lathe.Rotor drives the signal that feed screw nut rotates, and with encoder output, has formed a kind of simple for structure, positioning accuracy and repetitive positioning accuracy is high, service-strong Digit Control Machine Tool nut directly drives the numerical control feeding device.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Can find out that from structural representation of the utility model shown in Figure 1 and the A-A cutaway view of Fig. 2 the utility model mainly contains: the motor cabinet 2 of servomotor, motor stator 3, rotor 12, in groups bearing 11, bearing gland 10, inner ring pressure ring 9, round nut 7, leading screw body 8, feed screw nut 13, encoder 4, encoder support 5, be with compositions such as 6 synchronously.The motor cabinet 2 of servomotor is directly installed with screw and taper pin and is fastened on the moving-member 1 of lathe, and motor stator 3 is fixed in the motor cabinet 2.Motor cabinet 2 between rotor 12 with angular contact ball in groups bearing 11 be supported on.The angular contact ball outer ring of bearing 11 in groups is tightened to one with bearing gland 10 and motor cabinet 2, and the angular contact ball inner ring of bearing 11 in groups is tightened to one with inner ring pressure ring 9 and round nut 7 and rotor 12.The secondary feed screw nut 13 of feed screw is installed in rotor 12 centre bores, guarantee with the coaxial condition of rotor under, be fastened on screw on the end face of rotor 12.The two ends of leading screw body 8 then directly are axially fixed on the fixture 14 of lathe.Rotor 12 drives the signal that feed screw nut 13 rotates, with encoder 4 outputs.Encoder 4 is installed on the encoder bearing 5, and encoder bearing 5 is installed on the moving-member 1 of lathe, between the power shaft of rotor 12 and encoder 4 with being with 6 transmissions synchronously.
