Embodiment 1

[0029] Such as figure 1 As shown, the present invention is a rotatable two-way telescopic mechanism, including a mounting base 1, a motion executive assembly 2, a motor 3, a driving gear 4, a motor 2 5, a synchronous pulley 6, a synchronous belt 7 and a synchronous pulley 2 14. The motion actuator component 2 passes through the two guide holes on the mounting base 1, and is connected by a bushing to realize the relative linear motion relative to the mounting base 1. The motor one 3 is fixed on the mounting base 1 and installed on it There is a driving gear 4, and when the driving gear 4 rotates, it drives two oppositely installed pinion shafts 8 to realize opposite linear motion. The second motor 5 is fixed on the mounting seat 1 through a connecting piece, and a synchronous pulley 1 6 and a synchronous belt 7 are installed on it. , motor 5 drives synchronous pulley one 14 through synchronous belt 7, and then drives transmission key 13. When the motor 3 is energized to drive ...

Embodiment 2

[0031] Such as figure 2 As shown, the motion execution assembly 2 includes a gear shaft 8, a chuck 9, an end shaft 10, a sleeve 11, a rotating mandrel 12 and a transmission key 13, and the two gear shafts 8 on the motion execution assembly 2 are cylindrical shafts. , one end of which is processed with a tooth shape, one end is the same diameter as the body, and can be used as a guide shaft, and the other end is processed with threads, which can be used for screw fastening. Two gear shafts 8 are installed opposite to each other, and mesh with the drive gear 4 between them. , one end of the pinion shaft 8 near the teeth is fixedly connected to the chuck 9, the other end passes through the sleeve in the other chuck, the tooth shape is inward, the chuck 9 is fixed on the sleeve 11 by screws, and the end shaft 10 passes through The sleeve 11, the bottom of the terminal shaft 10 is a disk stuck outside the sleeve 11, and the transmission key 13 is fixed on the end of the rotating m...

Embodiment 3

[0033] Such as Figure 5 As shown, the mounting seat 1 is the basic mounting part of this component, and the rest of the components are directly or indirectly installed on it. At the same time, the mounting seat 1 is also the interface for the external installation of the whole set of mechanisms, so the mounting seat 1 can be composed of one part It can also be spliced ​​and connected by multiple parts. There are many holes on the mounting base for the purpose of reducing weight and saving materials, as well as preparing for the installation of the mechanism on the overall machine.

Abstract

The invention discloses a rotatable two-way telescopic mechanism, which comprises a mounting base, a motion execution assembly, a motor I, a driving gear, a motor II, a synchronous pulley I, a synchronous belt and a synchronous pulley II, wherein the motor I and the motor II are fixedly connected to on mounting base, the motor I drives the motion execution assembly to perform telescopic motion through the driving gear, the motor II is sleeved with the synchronous pulley I, and the motor II drives the synchronous pulley II through the synchronous belt, so that the motion execution assembly is enabled to perform rotary motion. The telescopic motion and rotary motion do not interfere with each other, and composite motion can be carried out. The rotatable two-way telescopic mechanism is simplein structure and good in synchronization performance.

Description

technical field [0001] The invention relates to the field of a bidirectional telescopic mechanism, in particular to a rotatable bidirectional telescopic mechanism. Background technique [0002] With the rapid development of my country's industry, the requirements for machine automation are increasing day by day. The country has invested heavily in artificial intelligence, and the popularity of mechanical automation is also a manifestation of a country's comprehensive strength. At present, a certain service robot has a requirement for the arm to stretch and rotate at a specified angle when it is working, and the volume and load weight of the service robot are strictly limited. The existing technology can only realize the function of two-way stretching. Other methods may have problems such as large volume, heavy weight, complex structure, and poor synchronization of expansion and rotation. [0003] The present invention overcomes all the above-mentioned shortcomings, and is ...
