Rotary distribution unit of the manipulator

Abstract

This utility model relates to mechanical engineering, specifically to manipulators, and can be used to mechanize and automate technological processes. The manipulator's rotary distribution unit consists of a rigidly connected detachable joint and a tubular element, onto which a supporting body is rotatably mounted. The supporting body is connected via crossbars to a mounting plate, which is rigidly connected via a lower tubular element to an element providing connection to the manipulator's actuator.

Description

[0001] Technical field

[0002] The utility model relates to the field of mechanical engineering, in particular to manipulators, and can be used for the mechanization and automation of technological processes.

[0003] Technology Level

[0004] Publication WO 2009079350 A1, June 25, 2009, discloses a rotary joint for a manipulator consisting of a rigidly connected detachable joint and a tubular element onto which a housing is rotatably mounted. A disadvantage of this prior art solution is that the housing and integrated control channels are load-bearing elements, bearing the full weight of the load. This leads to deformation of the rotary joint's sealing surfaces under axial and bending loads, accelerated seal wear, loss of seal integrity, and locking of the rotary joint when handling heavy loads.

[0005] The utility model is aimed at overcoming the shortcomings of the state of the art and, when implemented, allows for the achievement of a technical result consisting in increasing the reliability of the manipulator unit.

[0006] Disclosure of Utility Model

[0007] To achieve the specified technical result, a rotary distribution unit of a manipulator is proposed, consisting of a detachable connection and a tubular element rigidly connected to each other, on which a supporting body is mounted with the possibility of rotation, wherein the supporting body is connected by crossbars to a mounting plate, rigidly connected by means of a lower tubular element to an element that ensures connection with the actuator of the manipulator.

[0008] In an additional embodiment of the utility model, the mobility of the connection between the supporting body and the tubular element is ensured by a bearing assembly.

[0009] In another embodiment, a device for supplying media is located inside the output link of the manipulator and the tubular element, made in the form of flexible tubes that are connected to the fixed part of the multi-channel rotary joint, rigidly connected to the tubular element and the movable part of the multi-channel rotary joint, rigidly connected to the mounting plate, as well as to control buttons through the movable part of the multi-channel rotary joint.

[0010] It is also assumed that the control buttons may be located on the outer casing or on the supporting casing, or on the mounting plate, or on the control panel.

[0011] The description below provides information regarding the implementation of the utility model.

[0012] Implementation of a utility model

[0013] For a clearer understanding of the essence of the utility model, the description is supplemented with references to the positions of the explanatory drawing, according to which the following is presented:

[0014] 1 - supporting body;

[0015] 2 - tubular element (hollow pipe);

[0016] 3 - bearing unit;

[0017] 4 - flange (detachable connection);

[0018] 5 - output link;

[0019] 6 - traverse;

[0020] 7 - mounting plate;

[0021] 8 - lower tubular element (down tube);

[0022] 9 - lifting flange;

[0023] 10 - actuator;

[0024] 11 - flexible tubes;

[0025] 12 - movable part;

[0026] 13 - fixed part;

[0027] 14 - controls (buttons);

[0028] 15 - outer casing.

[0029] The device operates as follows.

[0030] The output link of the manipulator 5, the flange 4 and the hollow pipe 2 are connected and are fixed.

[0031] In the proposed solution, a rotating unit is installed on them via a bearing unit 3, which includes: a supporting body 1, a crossbar 6, a mounting plate 7, a lower pipe 8, a lifting flange 9 and an actuator 10. The bearing unit 3 interacts with the supporting body 1, connected via crossbars 6 to the mounting plate 7. In turn, the mounting plate 7 is rigidly connected to the lower pipe 8, which is connected via the lifting flange 9 to the actuator of the manipulator 10. Connecting the elements in this manner allows for free rotation of the supporting body and the elements connected to it.

[0032] By making the connections in the manner specified, the multi-channel rotary joint formed by the movable 12 and fixed 13 parts located in the supporting body takes up the load and operates only to supply the medium to the flexible tubes 11 during rotation, in order to provide communication between the rotating actuator 10 and feedback with the control buttons 14, which, in particular, may be located on the outer body 15 (without excluding their location on the supporting body, or on the mounting plate, or on the control panel). In this case, the above-described unit (supporting body 1, crossbar 6, mounting plate 7, lower pipe 8, lifting flange 9 and actuator 10) has a load-bearing capacity and the ability to rotate relative to the fixed hollow pipe 2.

[0033] The introduction of a power circuit, specifically consisting of a supporting body, allows for the implementation of a rotary device with a separately installed power circuit and multi-channel rotary joint, which improves the reliability of one of the manipulator's key components. The power circuit supports the payload mass by transferring the load-bearing load to the manipulator's output link.

[0034] Also, the implementation of the manipulator's rotary device with a separately installed power circuit with the ability to rotate in the design of the manipulator's rotary device allows for increasing the maintainability and lifting capacity of the manipulator.

[0035] By simplifying the supporting element of the rotary device and dividing the supporting and distribution parts into different mechanisms, the production, replacement, and scaling of the power circuit are simplified.

[0036] In addition, the implementation of a rotary device with a separately installed external casing and control elements allows for improved ergonomics of manipulator control.
