Embodiment 1

[0025] Such as figure 1 with figure 2 As shown, it is a schematic diagram of the principle of the double-layer fold-back drive mechanism of the embodiment of the present invention. The double-layer fold-back drive mechanism of the embodiment of the present invention includes a motor frame 31, an interlayer transmission mechanism 32, a motor 311, a screw 34, and a screw 34. Matched nut 35.

[0026] The motor 311 is fixed in the motor frame 31 and is connected to the first rotating body 321 of the interlayer transmission mechanism 32 through an output shaft. In practical applications, because the output speed of the motor 311 may be different from the actual required speed, it can also include a speed reduction component to adjust the speed of the motor output. The speed reduction component is arranged at the output end of the motor 311, and the output The shaft is connected to the output end of the motor 311 through the reduction assembly.

[0027] The screw 34 and the nut 35 are ...

Embodiment 2

[0040] Such as Figure 3 to Figure 6 As shown, it is a schematic diagram of the principle of the double-layer folding back driving mechanism of the second embodiment of the present invention. figure 1 On the basis of the structural diagram shown, a driven part 38 is added. The driven component 38 is rotatably connected with the motor frame 31 through the first rotating shaft 40, and is driven by the nut 35 ( Figure 3 to Figure 4 The two-way arrow under the middle nut represents the sliding direction of the nut), and the driven part 38 can rotate relative to the motor frame 31 ( image 3 The arrow at the end of the driven part in the middle represents the direction of rotation of the driven part).

[0041] Further, since the movement trajectory of the driven component 38 is different from that of the nut 35, and the movement trajectory is not parallel or in a straight line, a flexible connection component or a bendable connection component is preferably used between the driven comp...

Embodiment 3

[0051] Such as Figure 7 to Figure 10 As shown, it is a schematic diagram of the principle of the double-layer folding back driving mechanism of the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the driven component of this embodiment includes a two-stage connecting rod structure, and accordingly, the way the nut drives it is also different.

[0052] One end of the first-stage link 42 of the two-stage link structure is rotatably connected to the motor frame 31 through the first rotating shaft 40, and one end of the second-stage link 43 of the two-stage link structure is connected to the first-stage link 42 The other end is rotatably connected through the second rotating shaft 44, a first pull rod 45 is provided between the second-level connecting rod 43 and the motor frame 31, and one end of the first pull rod 45 can be connected to the motor frame 31 through the third rotating shaft 46 The other end of the fir...

Abstract

The embodiment of the invention provides a multi-stage rotating mechanism with double-layer fold-back driving. Driven parts comprise connecting rods in multiple stages, a motor is connected with a first rotating body, a screw and a nut are arranged below a motor frame, the screw is connected with a second rotating body, the first rotating body and the second rotating body are in transmission connection, the nut is provided with a connecting part, the connecting rods in multiple stages are connected in sequence, the first-stage connecting rod is connected with the motor frame, the first-stage connecting rod is connected with the connecting part, a first pull rod is connected with the motor frame and a second-stage connecting rod, and a second pull rod is connected between every connecting rods of two stages with a connecting rod of one stage at interval. According to the multi-stage rotating mechanism with double-layer fold-back driving, by adopting a double-layer fold-back transmission structure and being matched with a special design of the screw rod and the nut, the original output of the power source and the driving output to the driven components are respectively located at two layers, the fold-back is realized through an interlayer transmission mechanism, and thus the space occupied by the axial transmission output is saved.

Description

Technical field [0001] The embodiment of the present invention relates to a driving mechanism, in particular to a multi-stage rotating mechanism driven by a double-layer folding back. Background technique [0002] The manipulator can imitate certain motion functions of human hands and arms, and is used as an automatic operating device for grasping, transporting objects or operating tools according to a fixed program. Manipulators are the earliest industrial robots and the earliest modern robots. They can replace human labor to achieve mechanization and automation of production, and can operate in harmful environments to protect personal safety. Therefore, they are widely used in machinery manufacturing, metallurgy, Departments of electronics, light industry and atomic energy. In a broad sense, manipulators are not necessarily complex structures that imitate human hands. In industrial production, devices similar to arm structures are also widely used, such as driving a rotatable ...
