Abstract
The utility model relates to a direct-driven screw rotating device, and belongs to the field of machine tools. A hollow shaft torque motor is arranged on the direct-driven screw rotating device. The direct-driven screw rotating device is characterized in that a lead screw passes through the hollow shaft torque motor; a rotor of the hollow shaft torque motor is connected with a rotating screw to form a whole body; the rotating screw is rigidly coupled to the lead screw; a shell of the hollow shaft torque motor is fixedly connected with a moving component; and the hollow shaft torque motor directly drives the screw to rotate so as to realize that the moving component moves linearly along the lead screw. The hollow shaft torque motor is rigidly coupled to the lead screw, so that the machine tool structure is simplified, and the dynamic performance, the motion speed and the machining accuracy of the machine tool are improved.
Description
Technical field
The utility model relates to machine tool field, specifically a kind of be applied on the machine tool motion axle to drive the moving-member motion directly drive the screw rotary actuator.
Background technology
As everyone knows; In traditional machine tool screw mandrel drive mechanism; Between motor and screw mandrel or motor and the screw is to be connected through parts such as shaft coupling, ringfeder, cog belt, gears, rotatablely moving of motor is changed into the rectilinear motion of screw on screw mandrel, and then drive the moving-member motion.This drive mechanism must pass through intermediate link, and the precision of driving-chain and rigidity are difficult to guarantee, influence machine tool capability.
Summary of the invention
In order to overcome the deficiency of prior art; Simplify machine tool structure; Improve rigidity, dynamic property, movement velocity and the machining accuracy of lathe; The utility model provides a kind of screw whirligig that directly drives, and has solved to have the driving-chain precision that intermediate links such as cog belt, gear cause and the problem of insufficient rigidity because of drive mechanism, can effectively improve the performance of lathe.
The utility model solves the technical scheme that its technical problem adopted: a kind of screw whirligig that directly drives, be provided with the hollow shaft torque motor, and it is characterized in that; Screw mandrel passes the hollow shaft torque motor; The rotor of hollow shaft torque motor links into an integrated entity with the rotation screw, and rotation screw rigidity is coupling on the screw mandrel, and the shell of hollow shaft torque motor is connected fixing with moving-member; The hollow shaft torque motor directly drives the screw rotation, thereby realizes that moving-member is along the screw mandrel rectilinear motion.
The utility model also can be realized through following measure: the screw mandrel between hollow shaft torque motor and the screw is provided with swivel sleeve, and bearing is installed on the swivel sleeve.
The beneficial effect of the utility model is, hollow shaft torque motor and rotation screw rigidity are coupled, and simplified machine tool structure, improved lathe dynamic property, movement velocity and machining accuracy.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
