[0041] In the related art, the mechanical arm is a programmable, multifunctional, high-precision, and intelligent automated tool, and its use scenarios and roles are very wide; for example, in the fields of automobile assembly, electronic transfer, food processing, and metal processing, etc., it is used to provide production efficiency and reduce physical activity.

[0042] In actual production processes, different parts are produced by the line body, and different clamping tools need to be equipped during clamping for different parts. The connection mode of the clamping tool and the mechanical arm has multiple modes, such as electromagnetic mode and pneumatic mode.

[0043] However, the electromagnetic mode is difficult to be compatible with tool heads with small mass and strong load due to the electromagnet. The pneumatic mode needs to be equipped with an external air source, such as an air compressor, which causes the weight and volume of the mechanical arm to be large.

[0044] Therefore, the mechanical arm quick release device and the mechanical arm provided by the present application can reduce the volume and weight of the mechanical arm and be compatible with the load performance.

[0045] The embodiments of the present application will be described below in conjunction with Figures 1 to 8 .

[0048] The first end of the second component 2 and the first end of the first component 1 are used to be connected with the clamping tool and the moving end of the main body of the mechanical arm, respectively; the specific structure can be that the first end of the first component 1 and the first end of the second component 2 are both provided with a connecting groove to be clamped with the clamping tool or the moving end of the main body of the mechanical arm, or fixedly connected through a bolt; as shown in Figure 3 and Figure 6 , the second end of the second component 2 is provided with a clamping part 21, and the form of the clamping part 21 can be any form as long as it can be clamped with the clamping piece 3 to realize the connection of the first component 1 and the second component 2.

[0049] As shown in Figure 3 and Figure 4 , the clamping piece 3 is provided with at least one, that is, the number of the clamping piece 3 can be multiple, and the specific number can be set according to the clamping requirement; the clamping piece 3 is slidably connected with the second end of the first component 1 along the first direction X, as shown in Figure 8As shown, the clamping piece 3 is provided with a pressing portion 31 and a clamping portion 32, the pressing portion 31 is located outside the first component 1 along the first direction X, so as to be manually pressed or driven by the disassembling component 4, wherein the first direction X is parallel to the end face of the second end portion of the first component 1.

[0050] Wherein, the clamping piece 3 is driven to reciprocate by the pressing portion 31, so that the clamping portion 32 is clamped or separated from the clamping portion 21.

[0051] Specifically, in use, as shown in Figures 1 to 3 , the pressing portion 31 of the clamping piece 3 is pressed, so that the clamping piece 3 moves along the first direction X, and the clamping portion 32 of the clamping piece 3 is separated from the clamping portion 21 of the second component 2, so as to realize the separation of the first component 1 and the second component 2.

During reciprocating sliding of the dismounting component 4 relative to the first component 1, the dismounting part 42 can drive the clamping part 3 to reciprocate by pressing the pressing part 31.

[0057] During reciprocating movement of the dismounting component 4, as in the first position state, the dismounting part 42 on the dismounting component 4 presses the pressing part 31 on the clamping part 3, so that the clamping part 3 moves in the first direction X, and the clamping part 32 on the clamping part 3 is separated from the clamping part 21 on the second component 2, thereby realizing the separation of the first component 1 and the second component 2, and facilitating the dismounting of the first component 1 and the second component 2.
