Abstract
The invention discloses a kind of linkage mechanism based on ball screw pair, comprising: ball screw pair (1), ball pivot fixed base (2), ball pivot upper bracket (3), ball pivot undersetting (4), ball pivot adjustment pad (5), straight pin (6) and connecting rod (7).Described ball screw pair (1), comprising: ball screw, ball nut and ball.When external impetus drives ball nut to rotate, ball nut drives ball screw straight line motion by ball, and ball screw drivening rod (7) does the compound motion of straight line and rotation, and then the rocking bar promoting outside swings, and finally completes required movement output.Mechanism, by conjunction with ball screw pair (1) and connecting rod (7), had both achieved required movement output, had eliminated structural deviation, have compressed working space again.
Description
Technical field
The present invention relates to a kind of linkage mechanism, particularly a kind of linkage mechanism based on ball screw pair.
Background technique
Linkage mechanism kind is more, wherein the slide block slotted link mechanism motion transfer problem solved between mobile and swing.The kinematic relation of slide block slotted link mechanism is, tries hard to recommend action-oriented slide block and does straight line motion, drives rocking bar to swing by connecting rod.In some specific workplace, connecting rod is needed to be embedded in a relative narrow space, with the overall space of compression set.Traditional slide block slotted link mechanism, owing to considering less in space, takes up room comparatively large, is not suitable for the workplace of small space, and slide block, connecting rod and distant bar are in same plane, not only installation requirement is high, and cannot eliminate structural deviation, thus brings impact to mechanism and destroy.
Summary of the invention
The object of the present invention is to provide a kind of linkage mechanism based on ball screw pair, the problem of the motion conversion that solution narrow working space inside connecting rod mechanism moves and swings and structural deviation.
Based on a linkage mechanism for ball screw pair, comprising: connecting rod, also comprise: ball screw pair, ball pivot fixed base, ball pivot upper bracket, ball pivot undersetting, ball pivot adjustment pad and straight pin.Described ball screw pair, comprising: ball screw, ball nut and ball.The external cylindrical surface of ball screw and the inner cylindrical surface of ball nut are processed with spiral rolling track respectively, and ball is arranged in the spiral rolling track of ball nut and ball screw formation.Ball screw inside is processed with abdominal cavity, and abdominal wall is processed with step and screw thread.Ball pivot fixed base is threaded with ball screw and spacing to ball pivot fixed base by straight pin.Ball pivot upper bracket is placed on ball pivot fixed base, and ball pivot adjustment pad is placed in the middle of ball pivot upper bracket and ball pivot fixed base.Ball pivot undersetting is placed on the Intraabdominal step of ball screw.Connecting rod spherical one end is placed in the middle of ball pivot upper bracket and ball pivot undersetting, and the connecting rod the other end is flexibly connected with outside rocking bar.
Ball screw pair is a kind of device that rotary motion can be converted to straight line motion, when external impetus drives ball nut to rotate, ball nut drives ball screw motion by ball, and ball screw does straight line motion without spin under the effect of outside fixed guide.Because ball pivot upper bracket and ball pivot undersetting form a diameter of Spherical Volume in the abdominal cavity of ball screw, ball pivot upper bracket, ball pivot undersetting and connecting rod define a multivariant ball pivot node, during ball screw straight line motion, drivening rod does the compound motion of straight line and rotation, and then promote outside rocking bar swing, finally complete required movement output.
The present invention is combined ball screw pair with connecting rod, both achieved required movement output, eliminated structural deviation, have compressed working space again.

Embodiment
Based on a linkage mechanism for ball screw pair, comprising: connecting rod 7, also comprises: ball screw pair 1, ball pivot fixed base 2, ball pivot upper bracket 3, ball pivot undersetting 4, ball pivot adjustment pad 5 and straight pin 6.Described ball screw pair 1, comprising: ball screw 8, ball nut 9 and ball 10.The external cylindrical surface of ball screw 8 and the inner cylindrical surface of ball nut 9 are processed with spiral rolling track respectively, and ball 10 is arranged in the spiral rolling track of ball nut 9 and ball screw 8 formation.Ball screw 8 is processed with abdominal cavity, and abdominal wall is processed with step and screw thread.Ball pivot fixed base 2 is threaded with ball screw 8, and spacing with straight pin 6 pairs of ball pivot fixed bases 2.Ball pivot upper bracket 3 is placed on ball pivot fixed base 2, and ball pivot adjustment pad 5 is placed in the middle of ball pivot upper bracket 3 and ball pivot fixed base 2.Ball pivot undersetting 4 is placed on the Intraabdominal step of ball screw 8.The spherical one end of connecting rod 7 is placed in the middle of ball pivot upper bracket 3 and ball pivot undersetting 4, and connecting rod 7 the other end is flexibly connected with outside rocking bar.
Ball screw pair 1 is a kind of device that rotary motion can be converted to straight line motion, when external impetus drives ball nut 9 to rotate, ball nut 9 drives ball screw 8 to move by ball 10, and ball screw 8 does straight line motion without spin under the effect of outside fixed guide.Because ball pivot upper bracket 3 and ball pivot undersetting 4 form a diameter of Spherical Volume in the abdominal cavity of ball screw 8, ball pivot upper bracket 3, ball pivot undersetting 4 define a multivariant ball pivot node with connecting rod 7, during ball screw 8 straight line motion, drivening rod 7 does the compound motion of straight line and rotation, and then promote outside rocking bar swing, finally complete required movement output.
