DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1

[0027] Reference Figure 1-2 , which is the first embodiment of the present utility model, provides a multi-structure transmission teaching manipulator, including a frame mechanism 300, the frame mechanism 300 includes a swing arm 301, and the swing arm 301 is equipped with a bottom mechanism 100 and a transmission mechanism 200;

[0028] In addition, the bottom mechanism 100 includes a driving motor 101, the output end of the driving motor 101 is plugged into and connected to a straight shaft 103, the outer surface of the straight shaft 103 is fixedly sleeved with a worm 106, the side of the worm 106 is engaged with a worm wheel 107, the worm wheel 107 is fixedly sleeved with a flange 201 through a column, the top of the flange 201 is adapted to be installed with an inner support frame 202, the side of the inner support frame 202 is fixedly penetrated by a power motor 203, the power motor 203 is cooperated with a driving wheel 204 and a driven wheel 205, and the driven wheel 205 is plugged into and connected to the swing arm 301 through the center axis.

[0029] Specifically, the bottom mechanism 100 is arranged in coordination with the transmission mechanism 200 and the frame mechanism 300, so that the swing arm 301 can be rotated at any position for teaching. The plug-in connection between the drive motor 101 and the straight shaft 103 can be used to provide a power source for the transmission function. The engagement of the worm 106 and the turbine 107 changes the direction of rotation, which facilitates demonstration and teaching. The flange 201 is arranged in coordination with the inner support frame 202, so that the rotation of the worm gear 107 is further transmitted, thereby helping the self-rotation, and the display effect is comprehensive and continuous. The power motor 203 is arranged in coordination with the driving wheel 204 and the driven wheel 205, so that the gear speed decreases step by step. The plug-in connection between the driven wheel 205 and the swing arm 301 can make the rotation of the swing arm 301 continuous and stable, which can meet the display requirements of the robot.

[0030] Furthermore, the end face of the power motor 203 is plug-connected with the driving wheel 204 , the teeth of the driving wheel 204 are meshed with the driven wheel 205 , and the inner surface of the inner support frame 202 is rotatably connected to the secondary wheel 206 .

[0031] Preferably, the connection between the driving wheel 204 and the power motor 203 allows the power at the output end of the power motor 203 to be directly provided to the driving wheel 204, effectively improving the meshing efficiency. The rotational connection between the secondary wheel 206 and the inner support frame 202 can ensure that the side of the inner support frame 202 remains relatively stationary when it rotates, and the inner support frame 202 will not decline or detach.

[0032] It should be noted that the outer surface of the inner support frame 202 is fixedly connected to the side-moving motor 207, the output end of the side-moving motor 207 is fixedly connected to the sleeve shaft 208, the surface of the sleeve shaft 208 is plugged into and connected to the outer block 209, and the outer block 209 is movably in contact with the teeth of the secondary wheel 206.

[0033] Afterwards, the fixed connection between the side motor 207 and the inner support frame 202 reduces the vibration when the side motor 207 is running. The plug-in connection between the sleeve shaft 208 and the outer support block 209 can provide power for the inner support frame 202 to rotate to the lowest point, helping the inner support block 202 to rotate continuously.

[0034] Example 2

[0035] Reference Figure 2-3 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts for achieving a stable display effect of the manipulator.

[0036] Specifically, the frame mechanism 300 also includes a side bending plate 302, the bottom of the side bending plate 302 is rotatably connected to the swing arm 301, and the bottom of the side bending plate 302 is hingedly connected to a positioning shaft 303, and the positioning shaft 303 is rotatably sleeved with the top of the swing arm 301.

[0037] Furthermore, the rotational connection between the side bending plate 302 and the swing arm 301 allows the side bending plate 302 to rotate further flexibly, and the rotation teaching effect of the manipulator is better. The rotational connection between the alignment shaft 303 and the swing arm 301 helps the manipulator to fully demonstrate the transmission effect through the step-by-step transmission of multiple structures.

[0038] Preferably, a transmission rod 304 is rotatably sleeved on the outer side of the alignment shaft 303, one side of the transmission rod 304 is hingedly connected to a display rack 305, the top of the display rack 305 is fixedly connected to a control member 306, and the bottom of the control member 306 is adapted to be installed with a wedge claw 307.

[0039] The hinged connection between the transmission rod 304 and the display frame 305 allows the control member 306 to rotate accordingly, so that the control member 306 can stably control the wedge claw 307.

[0040] Example 3

[0041] Reference Figure 2-5 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts for achieving stable operation of the driving component.

[0042] Specifically, a plug 102 is fixedly connected to the side of the driving motor 101, a square frame 104 is fixedly sleeved on the side of the straight shaft 103, a bottom plate 105 is fixedly connected to the lower surface of the square frame 104, and a bearing 108 is adapted and clamped on the end face of the straight shaft 103.

[0043] Furthermore, the fixed connection between the plug 102 and the drive motor 101 allows the drive motor 101 to be continuously powered. The fixed arrangement of the square frame 104, the base plate 105 and the straight shaft 103 further helps to make the side transmission of the straight shaft 103 more uniform. The snap-fit ​​connection between the bearing 108 and the straight shaft 103 keeps the rotation concentricity of the straight shaft 103 unchanged, and the transmission is continuous and consistent.

[0044] Preferably, the radii of the driving wheel 204 and the driven wheel 205 are set differently, and the placement planes of the driving wheel 204 and the driven wheel 205 remain coincident.

[0045] Among them, the different radius settings of the driving wheel 204 and the driven wheel 205 cause the gear speed to change, and the rotation speed of the manipulator is more precise, which is conducive to the stability of the manipulator display.

[0046] Working principle: First, the driven wheel 205 and the secondary wheel 206 are fixedly sleeved on both sides of the swing arm 301, and then the outer block 209 and the sleeve shaft 208 are plugged and installed. The side motor 207 is fixedly connected to the sleeve shaft 208 and can be used in conjunction with the outer block 209 to provide stable rotation support for the secondary wheel 206. At the same time, the drive motor 101 and the power motor 203 are started. The drive motor 101 drives the straight shaft 103 and the worm 106 to rotate synchronously. After the worm wheel 107 engages with the worm 106, it drives the flange 201 to rotate synchronously, further allowing the swing arm 301 to rotate and extend at the same time. After that, during the extension process of the swing arm 301, the side bending plate 302 extends and expands under the rotation support of the positioning shaft 303, and the secondary transmission with the transmission rod 304 helps the wedge claw 307 to rotate at any angle.

Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, colors, directional changes, etc.) without departing substantially from the novel teachings and advantages of the subject matter described in this application. For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of the element may be inverted or otherwise changed, and the nature or number or position of the discrete elements may be altered or changed. Therefore, all such modifications are intended to be included within the scope of the present invention. The order or sequence of any process or method steps may be changed or reordered according to alternative embodiments.

Therefore, the present invention is not limited to the specific embodiments, but extends to various modifications that still fall within the scope of the appended claims.

[0048] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.

[0049] It will be appreciated that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will, for those of ordinary skill having the benefit of this disclosure, be a routine undertaking of design, fabrication, and production without undue experimentation.
