Description

Technical Field

[0001] The utility model belongs to the technical field of automation equipment, and in particular relates to a multi-joint slip ring. Background Art

An adjusting assembly 7 is arranged on the left side of the installation groove 2. The adjusting assembly 7 is used to adjust the auxiliary cylinder 3 to move to the right. A plurality of air outlet nozzles 8 are fixedly connected to the left side of the turntable 5 outside the installation groove 2. An air inlet nozzle 9 is fixedly connected to the right side of the stator base 1.

The guide blocks 301 are slidably connected inside the guide grooves 302. In this way, the auxiliary cylinder 3 can only slide horizontally along the guide grooves 302 to avoid rotation.

[0025] As Figure 1 and Figure 2 shown: In this embodiment, the turntable 5 includes a fixing portion 501 and a mounting portion 502. The number of bearings 4 is two, and the two bearings 4 are fixedly connected to the left and right sides of the outer surface of the mounting portion 502.

[0026] In this way, the turntable 5 can rotate relative to the stator base stably without shaking.

[0027] As Figure 2 and Figure 4 shown: In this embodiment, the adjusting assembly 7 includes an adjusting cap 701 threadedly connected to the left side of the stator base 1. A through hole 702 is formed in the middle of the adjusting cap 701. A spring 703 is installed between the right inner wall of the adjusting cap 701 and the auxiliary cylinder 3. The two sides of the spring 703 are not fixed, enabling the adjusting cap 701 to rotate.

[0028] In this way, by rotating the adjusting cap 701, the adjusting cap 701 moves to the right and compresses the spring 703. By increasing the elastic force of the spring 703, the right side of the turntable 5 is closely attached to the sealing ring 6, improving the service life.

[0029] As Figure 2 shown: In this embodiment, a plurality of first air holes 10 communicating with the air outlet nozzle 8 are provided on the left side of the fixing portion 501, a second air hole 11 communicating with the air inlet nozzle 9 is provided on the right inner wall of the mounting groove 2, the first air holes 10 penetrate through the right side of the mounting portion 502, and the sealing ring 6 is located between the first air holes 10 and the second air holes 11.

[0030] This setting can enable multiple air paths to be used simultaneously, and at the same time, the multiple first air holes 10 are independent of each other.

[0031] As Figure 2 and Figure 3 shown: In this embodiment, an annular groove 12 is provided on the right inner wall of the mounting groove 2, the right side of the sealing ring 6 is fixedly connected inside the annular groove 12, the left side of the sealing ring 6 is in contact with the right side of the mounting portion 502, the number of the sealing rings 6 is two, and the cross section of the sealing ring 6 is a triangular structure and is provided with rounded corners.

[0032] This setting uses two sealing rings 6, and the cross section of the sealing ring 6 adopts a triangular structure, which not only reduces the friction during rotation, but also has better compression performance, is more conducive to the relative rotation between the turntable 5 and the stator base 1, and will not cause air leakage.

[0033] Working principle: When in use, the turntable 5 is sleeved inside the stator base 1, the stator base 1 is installed and fixed through an external bracket, the air outlet nozzle 8 on the left is connected to the cylinder, and the air inlet nozzle 9 on the right is connected to the air pump. Since the turntable 5 can rotate relative to the stator base, when the cylinder rotates together with the turntable 5, it will not cause the air duct connected to the cylinder to become knotted. In order to enable multiple air paths to be used simultaneously, an air inlet nozzle 9 is fixedly connected to the right side of the stator base 1, a plurality of air outlet nozzles 8 are fixedly connected to the left side of the turntable 5, and at the same time, the multiple first air holes 10 are independent of each other. In order to ensure the tightness between the first air holes 10 and the second air holes 11, a sealing ring 6 is provided between the turntable 5 and the right inner wall of the mounting groove 2. At the same time, the cross section of the sealing ring 6 adopts a triangular structure, which not only reduces the friction during rotation, but also has better compression performance, is more conducive to the relative rotation between the turntable 5 and the stator base 1, and will not cause air leakage. After long-term use, rotate the adjusting cap 701. At this time, the adjusting cap 701 moves to the right and compresses the spring 703, and the right side of the turntable 5 is tightly attached to the sealing ring 6 by increasing the elastic force of the spring 703, improving the service life.
