[0002] With the continuous development of science and technology and industry, various electrical slip rings have been born one after another to provide air pressure, electric energy, electric signals, etc. for rotating parts, and are used in different fields, such as medium, high and low dome cameras in the security field, automatic rotating platforms, automatic revolving doors, automatic packaging equipment and robots, etc. Different fields have different technical requirements for electrical slip rings. With the development of science and technology, the application occasions of equipment in various application fields have increased, and higher requirements have been put forward for electrical slip rings.

[0003] As a highly efficient workpiece clamping tool, pneumatic chucks are widely used in automated production lines, CNC machine tools, robotics, and other equipment. Pneumatic chucks utilize compressed air as a power source, controlling pneumatic components to rapidly tighten and loosen the jaws. They offer advantages such as fast response, ease of operation, and low maintenance costs.

[0004] A common application of electrical slip rings is their ability to clamp and rotate workpieces when combined with pneumatic chucks. However, when a workpiece is threaded to another structure, rotation can cause axial displacement, requiring the pneumatic chuck to accommodate this displacement. Currently, this axial displacement of the workpiece using pneumatic chucks and electrical slip rings is often achieved through linear drive modules, which are complex and costly.

[0005] Therefore, it is necessary to improve and optimize the existing electrical slip rings so that they can better meet user needs. Utility Model Content

Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0017] The terms "front", "back", "left", "right", "inside", and "outside" used in this specification are for the purpose of clarification only and are not intended to limit the applicable scope of the present invention. Any changes or adjustments to the relative relationships thereof without substantially changing the technical content shall be deemed to be within the applicable scope of the present invention.

[0018] In the following descriptions of the embodiments, unless otherwise specified or limited, the term "connection" and other terms should be understood in a broad sense. For example, "connection" can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an indirect connection through an intermediate medium; it can refer to internal communication between two components or an interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0019] See also Figure 1-2 As shown, the present invention provides a floating rotation device comprising a pneumatic slip ring 1, a self-contracting mounting base 2, and a pneumatic chuck 3. Unlike conventional pneumatic slip rings and chucks, the self-contracting mounting base 2 in this embodiment enables the pneumatic chuck 3 to automatically approach the pneumatic slip ring 1 when pressure is applied. The specific structure is as follows:

[0020] The gas-electric slip ring 1 includes a stator 11 and a rotor 12. The stator 11 is provided with a first air hole in the circumference, and the rotor 12 is provided with a second air hole in the circumference. The first air hole and the second air hole are connected through the internal air path of the gas-electric slip ring.

[0021] A connecting shaft 121 is provided at one end of the rotor 12 for transmitting the rotational force of an external power device, and a sliding groove 122 coaxial with the connecting shaft 121 is provided at the other end of the rotor 12 opposite to the connecting shaft 121 .

[0022] The self-retracting mounting seat 3 comprises a seat body 31 and a transmission shaft 32 vertically disposed in the middle of the seat body 31. The transmission shaft 32 is shaped to match the slide groove 122 and is inserted into the slide groove 122, allowing the self-retracting mounting seat 3 to rotate with the rotor 12 and slide axially relative to the rotor 12. To achieve the above purpose, the transmission shaft 32 is square in shape in this embodiment. It will be understood by those skilled in the art that, provided that structural strength is met, the above effect can also be achieved using other shafts with non-circular cross-sections, such as spline shafts, and hole-matching structures.

[0023] Between the base 31 and the rotor 12, there are elastic members that force the two apart, as well as connectors that prevent them from separating. In this embodiment, the rotor 12 has a flange with a plurality of evenly spaced through holes. A guide rod 4 is movably sleeved within each of these holes. One end of the guide rod 4 has a nut 41 that is larger than the through hole, and the other end is vertically threadedly connected to the base 31. A spring 5 is sleeved on the guide rod 4, with its ends abutting against the flanges of the base 31 and the rotor 12, respectively. The guide rod 4 prevents the two from separating, while the spring 5 on the guide rod 4 forces the two apart.

[0024] The pneumatic chuck 2 is fixed to a self-shrinking mounting base 3, on which a clamping jaw 21 is mounted. A third air hole is provided on the peripheral wall of the pneumatic chuck 2. The third air hole and the second air hole are connected in a one-to-one correspondence through an air pipe. The above air circuit structure is conventional in the art and will not be described in detail here.

[0025] Therefore, an air pump is connected to the first air hole on the stator to drive the jaws 21 to grip the workpiece. An external power device, such as a servo motor, then rotates the rotor 12, which in turn rotates the pneumatic chuck 2. The jaws on the pneumatic chuck rotate the workpiece. When the workpiece moves axially, the self-retracting mount 3 automatically retracts to accommodate the workpiece's movement, eliminating the need for a complex linear drive module.

[0026] Compared with the prior art, the beneficial effects of the present invention are: it can realize the automatic contraction of the mounting seat for installing mechanical equipment on the gas-electric slip ring rotor, thereby automatically adapting to the axial displacement of the working workpiece. The equipment also has the advantages of simple structure, low cost, and simple and convenient installation.

Due to space limitations, not all implementation methods can be listed here one by one.

[0028] It should be noted that the above content is a further detailed description of the present invention in combination with specific implementation methods, and it cannot be determined that the specific implementation methods of the present invention are limited to these. Under the guidance of the above embodiments, those skilled in the art can make various improvements and modifications on the basis of the above embodiments, and these improvements or modifications fall within the scope of protection of the present invention.
