Abstract
The utility model discloses a linear motion structure is done in trapezoidal screw drive of motor drive, its constitution includes: fixing base, slip table, the fixing base on be fixed with a pair of guide arm, the slip table under both ends respectively have a pair of linear bearing, linear bearing cover on the guide arm, slip table lower extreme in the middle of the department be fixed with the copper nut, the copper nut twist soon on the lead screw, the lead screw both ends fix on the bearing frame in the fixing base, the one end of lead screw be connected with the shaft coupling, the shaft coupling be connected with the motor. The motor-driven trapezoidal screw rod is driven to do linear motion, is simple in structure and convenient to operate, is driven by the motor, can be finely adjusted according to requirements, and is quite stable in back-and-forth uniform linear motion.
Description
Technical field
This utility model relates to structure of linear motion technical field, is specially a kind of motor and drives trapezoidal screw transmission to do structure of linear motion.
Background technology
The pneumatic actuation that traditional line motion structure uses, speed can follow air pressure change, be affected according to by field condition, and speed can not accurately regulate, and driving force is unstable, can be with air pressure change, and start bit needs makees buffer unit.
Utility model content
The purpose of this utility model is to provide a kind of motor to drive trapezoidal screw transmission to do structure of linear motion, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of motor drives trapezoidal screw transmission to do structure of linear motion, its composition includes: fixing seat, slide unit, it is characterized in that: on described fixing seat, be fixed with pair of guide rods, under described slide unit, two ends respectively have a pair linear bearing, and described linear bearing is enclosed within guide rod, and described middle, slide unit lower end is fixed with copper nut, described copper nut is screwed on screw mandrel, describedScrew mandrelTwo ends are fixed on the bearing block in fixing seat, and one end of described screw mandrel connects has shaft coupling, described shaft coupling to be connected with motor.
Compared with prior art, the beneficial effects of the utility model are: this motor drives trapezoidal screw transmission to do structure of linear motion and is simple and convenient to operate, and use motor to drive, and speed can be finely tuned on request, linear uniform motion back and forth, the most steadily.
