Description

Technical Field

[0001] The utility model relates to the technical field of robot steering components, and particularly relates to a robot joint steering assembly. Background Art

[0002] With the progress of technology, there are more and more types of electronic products, and robots are one of them. Among the various mobile service robots, in order to meet the requirements of high-autonomy and high-efficiency service work, it is often necessary for the robot's arm to be able to rotate for flexible bending, which requires the robot arm to have a joint steering assembly.

[0003] The existing publication number is CN220741230U, and the name is a steering mechanism, which includes a fixing member, and a driving assembly, a steering gear and an angle measuring assembly respectively arranged on the fixing member. In the utility model, the single-turn absolute encoder counts the number of rotation turns of the planet carrier through the sensing part; and the reduction ratio of the planetary reduction mechanism is equal to the reduction ratio between the steering gear and the transfer gear, which makes the number of rotation turns of the planet carrier the same as that of the steering gear assembly.

[0004] However, the above-mentioned steering mechanism can drive the robot arm to perform horizontal circular motion through the drive of the gear, driving the arm to perform horizontal deflection motion. However, the above-mentioned steering mechanism cannot vertically deflect to change the deflection height of the arm, affecting the flexibility of the robot arm adjustment.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restricts the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0021] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps described in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for the sake of convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0022] In the description of the present invention, it should be understood that the orientation terms such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal", and "top, bottom" usually indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Without contrary explanation, these orientation terms do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus cannot be construed as limiting the scope of protection of the present invention; the orientation terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0023] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations during use or operation in addition to the orientation depicted in the figure for the device. For example, if the device in the attached drawing is inverted, a device described as "above or over other devices or structures" will then be positioned "below or under other devices or structures". Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0024] In addition, it should be noted that the use of terms such as "first", "second" etc. to define components is merely for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present utility model.

[0025] As Figures 1 to 4 shown, a robot joint steering assembly includes a steering member 1 and a lifting member 2. The steering member 1 includes a rotating plate 11. At the center of the top surface of the rotating plate 11, a steering seat 111 is vertically and fixedly penetrated. And a rotating column 12 is rotatably connected through the steering seat 111 in the vertical direction. At the bottom end of the rotating column 12, a driven gear 13 is horizontally fixed. The lifting member 2 includes a bottom plate 21. The bottom plate 21 is horizontally fixed on the top end surface of the rotating column 12. And on the top surface of the bottom plate 21, two deflecting plates 22 are symmetrically and vertically fixed. A rotating frame 23 is arranged on the two deflecting plates 22. And at the bottom of the rotating frame 23, a rotating shaft 231 is horizontally fixed. The rotating shaft 231 is rotatably connected to the rotating frame 23. On the top surface of the rotating frame 23, a hole block 232 is fixed. On the rotating shaft 231, a pushing plate 24 is fixed. And a pushing hole 241 is penetrated through the pushing plate 24.

And the hole seat 25 is rotatably connected to the rotating frame 261 at the bottom end of the hydraulic rod 26. During use, according to requirements, the rotating column 12 on the rotating plate 11 rotates, driving the bottom plate 21 on the lifting member 2 to rotate horizontally to the position for lateral deflection. Then, the hydraulic rod 26 is started to extend, pushing the pushing plate 24 on the rotating shaft 231 of the rotating frame 23, driving the rotating frame 23 to rotate on the deflecting plates 22, thereby facilitating the switching of the position height for use, so that the horizontal and height deflections of the robot arm can be carried out simultaneously, ensuring the flexibility of the adjustment of the robot arm.

[0026] In one embodiment, asFigure 2 and 3 As shown in 3 , a driving motor 15 is vertically fixed on the bottom surface of the rotating plate 11, and a driving gear 151 is horizontally fixed at the output end of the driving motor 15.

During use, it is fixed by the fixing screw 141 at the bottom end of the supporting housing 14, and then the driving motor 15 is started to drive the driving gear 151 to rotate, driving the lifting member 2 to deflect.

[0027] In this embodiment, during use, the rotating column 12 on the rotating plate 11 rotates according to requirements, driving the bottom plate 21 on the lifting member 2 to rotate horizontally, deflecting the position for lateral deflection. Then, the hydraulic rod 26 is started to extend, pushing the push plate 24 on the rotating shaft 231 of the rotating frame 23, driving the rotating frame 23 to rotate on the deflecting plate 22, thereby facilitating the switching of the position height for use.
