Set up one or more other components. When a component is referred to as being "directly" on another component, no other component is provided between the two components.

Please refer to the first to third figures. The automatic swinging device 10 provided by the preferred embodiment of the present invention mainly includes a base 20, a turntable 30, a motor 40, a screw 50, and a nut 60. And a shaft 70.

The base 20 includes a body 22 and a mounting assembly 24 secured to one side of the body 22. The mounting assembly 24 includes a substrate 242 fixed to the body 22, two mounting bases 244 fixed to the base plate 242, and a rail 246 protruding from the base plate 242 and located between the two mounting bases 244. A top surface 221 of the body 22 is provided with a recess 222. The recess 222 is provided with a circular protrusion 224 and a three-arc bump 226 located at the periphery of the protrusion 224, and the center of the circular protrusion 224 is further A pivot 228 protrudes.

The turntable 30 includes a disk body 32 and a connecting rod 34. One end of the connecting rod 34 is fixed to one end of the disk body 32, and the connecting rod 34 has a recess from the other end thereof toward the disk body 32. Long slot 342. A circular protrusion 322 protrudes from the bottom of the disk body 32, three arcuate protrusions 324 located at the periphery of the protrusion 322, and two larger curved protrusions 326 located at the periphery of the protrusions 324, and the A set of holes 328 is further provided in the center of the circular protrusion 322. The turntable 30 is sleeved on the pivot 228 of the base 20 by the sleeve hole 328, and can be swung around the pivot 228, and the convex The blocks 322, 324 are in surface contact with the bumps 224, 226 of the base 20, and the bumps 326 are also in surface contact with the top surface 221 of the base 20.

It should be noted that the pivotal relationship between the base 20 and the turntable 30 is not limited to the embodiment, as long as the turntable 30 can be pivoted relative to the base 20 with a pivot as a center. For example, the base 20 and the turntable 30 can also be respectively provided with socket holes and pivots to be pivotally connected to each other. In addition, the turntable 30 is in surface contact with the base 20 by the bumps 322, 324, and 326, so that the turntable 30 can be smoothly disposed on the base 20 without excessive friction due to excessive contact area. Resistance, but the contact relationship between the base 20 and the turntable 30 is not limited to those provided in this embodiment. Moreover, the long slot 342 does not have to be open at one end of the connecting rod 34, but may be a perforated shape of a closed shape.

The motor 40 is fixed to one of the mounting seats 244. The two ends of the screw 50 are rotatably respectively disposed on the two mounting bases 244 and can be driven by the motor 40.

The nut 60 is screwed to the screw 50 and is slidably embedded in the rail 246 of the base 20 . The shaft 70 is fixed on the top of the nut 60 and, in this embodiment, The shaft 70 is more fixedly sleeved with two bearings 80. The shaft 70 and the bearings 80 are disposed in the long slot 342 of the turntable 30; thereby, the nut 60 can be driven by the rotating screw 50. And the linear movement along the screw 50 and the rail 246, at the same time, the shaft 70 and the bearings 80 will drive the turntable 30 to swing relative to the base 20 as the nut 60 moves (as shown in the fourth figure to The sixth figure shows) and the bearings 80 will roll along the wall of the slot of the long slot 342.

It is worth mentioning that the number of the bearings 80 provided by the shaft 70 is not limited, and the shaft 80 can be directly slid along the hole wall of the long slot 342 without the bearing 80, but the bearing 80 is provided. The design can reduce the friction and make the automatic swing device 10 operate relatively smoothly. In addition, in this embodiment, the rail 246 of the base 20 is a ridge, and the nut 60 has a recess 62 embedded in the rail 246 (as shown in the third figure, wherein the nut 60 The base 246 of the base 20 can also be a recess, and the nut 60 has a protrusion embedded in the rail 246; and the base 20 can also be provided with no track 246. However, the design of the track 246 enables the nut 60 to move more reliably in a straight line.

In the automatic swinging device 10 provided by the present invention, the motor 40 can be a general equal-speed motor, and the position of the nut 60 can be controlled by controlling the position of the nut 60 without using an angle encoder. Swing at a small angle. The automatic swinging device 10 can further provide an optical scale 90 for sensing the position of the nut 60 on the base 20, so as to more accurately control the position of the nut 60, thereby accurately controlling the swing angle of the turntable 30. . Regardless of whether or not the optical scale 90 is provided, the cost of the automatic swing device 10 is lower than that of the conventional swinging device controlled by the servo motor and the angle encoder.

Finally, it must be explained again that the constituent elements disclosed in the foregoing embodiments are merely illustrative and are not intended to limit the scope of the present invention. Alternatives or variations of other equivalent elements should also be the scope of patent application of the present application. Covered.
