Embodiment 1

[0039] This embodiment provides a mechanical arm, such as figure 1 and Figure 4 As shown, it includes a fixing device 11, a No. 1 arm 20, a No. 2 arm 40, a No. 3 arm 50 and a telescopic device 60. One end of the No. 1 arm 20 is rotatably connected to the fixing device 11, and the other end is rotatably connected to the No. 2 arm 40. In connection, the end of the second arm 40 opposite to the first arm 20 has a first channel 403 along the axial direction of the second arm 40 , and one end of the third arm 50 is slidably disposed in the first channel 403 .

[0040] The telescopic device 60 is detachably fixed on the No. 2 arm 40 , and the driving end of the telescopic device 60 is detachably connected to the No. 3 arm 50 for driving the No. 3 arm 50 to reciprocate and slide in the first channel 403 . The telescopic device 60 can be an electric push rod, a telescopic cylinder, a hydraulic cylinder, and the like.

[0041] In the above embodiment, the telescopic device 60 is det...

Abstract

The invention relates to the field of mechanical structures, in particular to a mechanical arm which comprises a fixing device, a first arm, a second arm, a third arm and a telescopic device, wherein one end of the first arm is rotatably connected with the fixing device; one end of the second arm is rotatably connected with the other end of the first arm, and the other end of the second arm is provided with a first channel in the axial direction of the second arm; one end of the third arm is slidably arranged in the first channel in a penetrating mode; and the telescopic device is detachably fixed to the second arm, and a driving end of the telescopic device is connected with the third arm and used for driving the third arm to slide in the first channel in a reciprocating mode. The telescopic device is detachably fixed to the second arm and the third arm, when the telescopic length of the third arm in the second arm needs to be changed, the telescopic device can be replaced, the telescopic device meeting the use requirement is replaced, and therefore the whole mechanical arm does not need to be replaced, and the applicability of the mechanical arm is improved.

Description

technical field [0001] The invention relates to the field of mechanical structures, in particular to a mechanical arm. Background technique [0002] As a commonly used mechanical structure, the robotic arm is widely used in all aspects of life, such as various mechanical processing, object grabbing, etc. In these applications, in order to adapt to various working environments, the robotic arm often uses interconnected multi-segment type structure, and each segment of the mechanical arm can rotate with each other. [0003] Multi-segment mechanical arms are often used to meet the needs of various angles and lengths, and in some mechanical arms, in order to make the length of the mechanical arm longer, telescopic cylinders are used to extend some mechanical arms, but this The length of elongation is limited to the telescopic cylinder, and the length that can be achieved after manufacture is fixed, so that the applicability of the mechanical arm is not strong.
