Technical Field

[0001] The utility model relates to the technical field of EMS intelligent electric monorail suspension conveyors, in particular to a rotary arm type translation switch mechanism. Background Art

[0002] The EMS intelligent electric monorail suspension conveyor uses formed aluminum alloy profiles as tracks. The carriages travel along the upper surface of the track, and the side of the track is the guide surface. In the actual production process, it is also necessary to set up a translation switch to realize the automatic diversion and merging of the trolleys. The translation switch is a key part to improve the production capacity of the production line. In the existing technology, electric push rods or cylinders are usually used as the translation force of the track.

[0003] However, in actual use, it was found that when an electric push rod is used as the translational force of the track, the speed of the electric push rod is slow and the accuracy requirement for the linear operation of the mechanism is high, which makes it difficult to meet the high production cycle requirements and increases the manufacturing cost. When a cylinder is used as the translational force of the track, an air source is required, which limits the site. Utility Model Content

One end of the rocker arm 14 is fixed to the output shaft of the motor reducer 141. The other end of the rocker arm 14 is rotatably connected to a connecting rod 3. The end of the connecting rod 3 away from the rocker arm 14 is rotatably connected to the movable frame 2. When the rocker arm 14 rotates, the movable frame 2 can be driven to slide through the connecting rod 3.

[0032] The motor reducer 141 directly drives the rocker arm 14 to rotate, and then the connecting rod 3 can drive the moving frame 2 to move back and forth in a straight line. The linear motion of the moving frame 2 is realized by the rotation of the rocker arm 14. The sliding efficiency of the moving frame 2 is high and can meet the high production cycle requirements. In addition, since the motor reducer 141 has a self-locking function, the angle of the rocker arm 14 can be rotated by the motor reducer 141, so that the stroke of the moving frame 2 can be accurately controlled, thereby improving the accuracy of the moving frame 2 sliding to the curved rail 21 or the straight rail 22 to connect with the introduction rail 11.
