Embodiment Construction
[0047] Further illustrate the present invention below in conjunction with accompanying drawing.
[0048] Such as Figure 1-3 As shown, a high-torque compact mechanical arm joint includes: joint housing 1, control electrical box 2, motor 3, high-speed reducer 4, low-speed reducer 5, synchronous pulley 6, output shaft 7, joint connection Shaft 8 , second connecting plate 9 , first connecting plate 10 , bearing seat 11 , first bearing 12 , grating ruler 13 , reading head 14 , second bearing 15 and intermediate connecting plate 16 .
[0049] Wherein, the joint housing 1 is a nearly cylindrical hollow structure. In order to facilitate disassembly and assembly, the joint housing 1 can be composed of multiple parts, and the specific combination method can be determined according to actual needs. Usually the joint shell 1 comprises an upper shell 1-1, a middle shell 1-2 and a lower shell 1-3, the middle shell 1-2 is composed of an integrally formed connecting plate and a fixing plate...

Abstract
The invention relates to a high-torque compact mechanical arm joint, which belongs to the technical field of mechanical arms. The problem of how to provide a mechanical arm joint capable of simultaneously having large output torque, large reduction ratio, and small joint length is solved. The mechanical arm joint of the present invention includes a joint casing, a control electric box, a motor, a high-speed reducer, a low-speed reducer, a synchronous pulley, an output shaft, a joint connection shaft, a first connecting plate, a second connecting plate, a bearing seat, The first bearing, the grating, the reading head and the second bearing, among them, the control electric box controls the motor to work, drives the high-speed reducer connected in series with the motor coaxially, and transmits the torque output by the high-speed reducer to the The input end of the low-speed reducer is finally connected to the shaft through the joint, and the output torque after the second deceleration of the low-speed reducer is transmitted to the next joint. The mechanical arm joint has the characteristics of large reduction ratio, compact structure, small dead weight, and large output torque.
Description
technical field [0001] The invention belongs to the technical field of mechanical arms, and in particular relates to a high-torque compact mechanical arm joint. Background technique [0002] The robotic arm is an automated mechanical device that can accept instructions and precisely locate a certain point in three-dimensional (or two-dimensional) space for operations. It has a wide range of applications in industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing, and space exploration. [0003] There are many types of manipulators with different shapes. Among them, the tandem manipulator is the most widely used due to its high flexibility. The tandem manipulator can be divided into space tandem manipulator and ground tandem manipulator. The manipulator is the key technology to realize the movement of the manipulator. On the one hand, the output torque of the manipulator joint determines the maximum working load of a manipul...
