DETAILED DESCRIPTION

[0050] 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 in conjunction with the accompanying drawings.

[0051] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and 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.

[0052] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0053] Example 1

[0054] Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, and this embodiment provides a mounting base for an industrial robot, which includes a positioning unit 1, including a support member 11, a screw member 12 penetrating the inner wall of the support member 11, a first rack 13 arranged on the outer side of the screw member 12, an outer gear ring 14 coaxially arranged with the support member 11, a limit block 15 penetrating the inner wall of the support member 11 and extending to the outer side thereof, and a connecting member 16 arranged inside the support member 11.

[0055] In this embodiment, the support member 11 is a platform with a certain size and thickness, and is located between the transmission units that meet the requirements of the internal installation of the support member 11. The interior of the support member 11 should also have a certain space;

[0056] The screw member 12 penetrates the side wall of the support member 11 and extends to the outside thereof, and one end of the screw member 12 is located outside the support member 11, so that it is more convenient for the staff to use tools to drive the screw member 12 to rotate;

[0057] The outer side of the screw member 12 is provided with an external thread structure A1, and the through hole opened inside the first rack 13 is provided with an internal thread structure A2 adapted to the external thread structure A1; and the screw member 12 and the first rack 13 are threadedly matched, so that the rotation of the screw member 12 can drive the first rack 13 to be spirally fed along the axial direction of the screw member 12;

[0058] It should be noted that the outer gear ring 14 has the same axis as the support member 11, and the inner wall of the support member 11 is provided with an inner wall that can limit the outer gear ring 14; so that the outer gear ring 14 will not leave the axial position of the support member 11 during the rotation process; and the first rack 13 is adapted to the outer gear ring 14, and the first rack 13 can drive the outer gear ring 14 to rotate during the horizontal movement process;

[0059] During the rotation of the outer gear ring 14, the protrusions arranged inside it can push the limit block 15 to move along a specific trajectory, so that the limit block 15 can pass through the inner wall of the support member 11 and extend to its outside; and the limit block 15 is arranged to conflict with the connecting member 16, so that the limit block 15 can be effectively used to achieve the limitation of the connecting member 16.

[0060] Furthermore, the rotating unit 2 includes a guide rod 21 passing through the inner wall of the support member 11, a second rack 22 slidingly arranged on the outside of the guide rod 21, a pushing member 23 arranged on the surface of the second rack 22, a lifting rod 24 passing through the top surface of the support member 11, and a support seat 25 rotatably arranged on the top surface of the support member 11.

[0061] In this embodiment, the structure of the guide rod 21 is similar to that of the screw member 12, and its outer side is a smooth rod-shaped structure, and a through hole is provided inside the second rack 22 matched with the guide rod 21, so that the second rack 22 can reciprocate along the axial direction of the guide rod 21;

[0062] The second rack 22 is meshed with the outer gear ring 14, and the outer gear ring 14 can drive the second rack 22 to move along the axis direction of the guide rod 21 during rotation;

[0063] It should be noted that the pushing member 23 and the second rack 22 are fixed by bolt connection, and the pushing member 23 moves with the second rack 22; during the movement of the pushing member 23, the end face of the pushing member 23 continuously squeezes the bottom of the lifting rod 24, thereby increasing the distance from the top of the lifting rod 24 to the outside of the support member 11, so that the support seat 25 can be lifted to a certain height, so that there is a certain distance between the support seat 25 and the support member 11, which makes it easier for the staff to twist the support seat 25, so that the mechanical arm installed on the surface of the support seat 25 rotates a certain angle, which is more convenient for the staff to adjust the corresponding angle.

[0064] When in use, the staff uses a tool to drive the screw member 12 to rotate. The rotation of the screw member 12 can drive the first rack 13 to move. The movement of the first rack 13 can drive the outer gear ring 14 to rotate along the axis of the support member 11; while the outer gear ring 14 rotates, it can squeeze the limit block 15; so that the limit block 15 passes through the inner wall of the support member 11 and cooperates with the connecting member 16, so that the position of the connecting member 16 can be fixed by the limit block 15; and the connecting member 16 and the support seat 25 are movably connected. When the position of the connecting member 16 is fixed, the support The movement position of the seat 25 is also subject to corresponding restrictions; at the same time, the outer ring gear 14 drives the second rack 22 to move along the axial direction of the guide rod 21 during the rotation process, so that the pushing member 23 set on the end face of the second rack 22 contacts the bottom of the lifting rod 24, so that the end of the lifting rod 24 is lifted to a certain height, and the end of the lifting rod 24 pushes the support seat 25 to move while moving, so that the bottom of the support seat 25 leaves the surface of the support member 11, so that the support seat 25 can be better rotated, and then the angle between the robot arm and the mounting base can be adjusted.

[0065] In summary, the present invention improves the flexibility of installation by making the mounting base and the mechanical arm rotatable, so that it can be adjusted to the optimal position more conveniently during the initial installation, without the need to repeatedly disassemble and install the bolts, thus saving a lot of time and labor costs. Secondly, the rotatable design allows for a quick response when the working angle of the robot needs to be fine-tuned during the production process, without interrupting the production line, thereby improving the continuity and efficiency of production.

[0066] Example 2

[0067] Reference Figure 2 - Figure 4 , which is the second embodiment of the present invention, and is different from the first embodiment in that: it also includes: the interior of the support member 11 is a hollow structure, the support member 11 includes a mounting hole 111 penetrating its outer wall and a guide rail 112 opened on the inner bottom surface of the support member 11; the screw member 12 penetrates the mounting hole 111 and extends to the interior of the support member 11; the first rack 13 includes a slider 131 arranged at the bottom thereof, and the slider 131 is adapted to the guide rail 112; the screw member 12 and the first rack 13 are threadedly matched; the rotation of the screw member 12 can realize the reciprocating motion of the first rack 13 along the axial direction of the screw member 12.

[0068] In this embodiment, the support member 11 is a truncated cone structure with a rectangular through hole at its center. An annular groove is provided inside the side wall of the support member 11. The inner wall with a smaller diameter of the groove fits tightly with the inner wall of the outer gear ring 14, ensuring that the axis of the outer gear ring 14 completely coincides with the axis of the support member 11 during rotation. This structural design not only ensures the stable rotation of the outer gear ring 14, but also improves the concentricity and operation accuracy of the entire system through the close fit between the groove and the outer gear ring 14.

[0069] Preferably, the mounting hole 111 passes through the side wall of the support member 11 and is connected to the annular groove provided inside the support member 11; and the position at which the mounting hole 111 is provided is parallel to the tangential direction of the rotation of the outer gear ring 14; at the same time, a guide rail 112 is provided on the bottom inner wall of the support member 11, and the guide rail 112 is adapted to the slider 131; the threaded cooperation between the screw member 12 and the first rack 13, and the sliding cooperation between the guide rail 112 and the slider 131, together achieve the effect of driving the first rack 13 to move in the horizontal direction when the screw member 12 rotates.

[0070] Specifically, when the screw member 12 rotates, the first rack 13 will produce axial displacement under the action of the thread due to the threaded fit between the screw member 12 and the first rack 13. At the same time, the sliding fit between the guide rail 112 and the slider 131 ensures smooth movement of the first rack 13 in the horizontal direction, avoiding poor movement caused by friction or jamming.

[0071] Furthermore, the support member 11 also includes an arc groove 113 opened on its inner wall; the first rack 13 is meshed with the outer gear ring 14; the inner wall of the outer gear ring 14 is in conflict with the inner wall of the support member 11, and the outer gear ring 14 is located inside the support member 11 and rotates; the outer gear ring 14 includes a protrusion 141 arranged on its inner wall, the protrusion 141 is located inside the arc groove 113, and the protrusion 141 can be in conflict with the end of the limit block 15.

[0072] In this embodiment, an arc groove 113 is further provided on the inner wall of the groove of the support member 11, and the first rack 13 is meshed with the outer gear ring 14. The first rack 13 moves in the horizontal direction to drive the outer gear ring 14 to rotate along the axis direction of the support member 11;

[0073] Specifically, a protrusion 141 is installed on the inner ring side wall of the outer gear ring 14 by bolt connection, and the protrusion 141 rotates synchronously with the outer gear ring 14; the movement space of the protrusion 141 is located inside the arc groove 113; the protrusion 141 is an arc-shaped protrusion structure, and its two end positions are flush with the inner wall of the outer gear ring 14, and a protrusion structure protruding from the inner ring side wall of the outer gear ring 14 is gradually formed from the two ends to the middle position.

[0074] Furthermore, the support member 11 also includes a slide groove 114 that is connected to the arc groove 113; the limit block 15 passes through the slide groove 114 and extends to its outside; a limit groove 161 that is compatible with the limit block 15 is opened inside the connecting member 16; the end of the limit block 15 can extend to the inside of the limit groove 161.

[0075] It should be noted that the end of the protrusion 141 can collide with the end of the limit block 15; and the number of the protrusions 141 corresponds to the number of the limit blocks 15, and the required number is at least one group.

[0076] Preferably, the end surface of the limit block 15 in contact with the protrusion 141 is a horizontal plane, and the other end of the limit block 15 is a trapezoidal block structure; sliders are provided on both sides of the limit block 15, and the sliders can make the limit block 15 move smoothly along the inner wall of the slide groove 114.

[0077] The connecting member 16 is arranged on the inner side of the center position of the supporting member 11, and the connecting member 16 is placed inside the supporting member 11; the limiting block 15 passes through the side wall of the supporting member 11 and extends to the inside of the limiting groove 161. The limiting block 15 can be used to limit the connecting member 16, so that the position between the connecting member 16 and the supporting member 11 is relatively fixed.

[0078] Specifically, the structure of the limit groove 161 is adapted to the end of the limit block 15, and both are trapezoidal block structures. During the snap-fitting process, the lower end of the trapezoidal block of the limit block 15 contacts the inner wall of the limit groove 161. When the connector 16 needs to be taken out from the inside of the support member 11, the inner wall of the limit groove 161 will squeeze the inclined surface of the end of the limit block 15, pushing the limit block 15 to shrink toward the inner wall of the support member 11, so that the end of the limit block 15 no longer extends out of the center position of the support member 11, ensuring that there is no obstacle in the installation position of the connector 16, which is convenient for the next installation. Even if the end of the limit block 15 slides to the center position of the support member 11, during the installation process, the staff can also press the end of the limit block 15 to the inner wall of the support member 11 in advance by pushing it by hand to ensure smooth installation.

[0079] When in use, the staff places the connecting piece 16 inside the groove in the center of the support piece 11, and then drives the first rack 13 to move in the horizontal direction by rotating the screw piece 12. The movement of the first rack 13 drives the outer gear ring 14 to rotate along the axial direction of the support piece 11; while the outer gear ring 14 rotates, it drives the protrusion 141 connected to its inner ring side wall to rotate. As the outer gear ring 14 rotates, the end face of the protrusion 141 continuously squeezes the end of the limit block 15, thereby pushing the other end of the limit block 15 to pass through the outside of the support piece 11, and engages with the limit groove 161, thereby realizing the use of the limit block 15 to fix the position of the connecting piece 16, thereby realizing the connection between the support piece 11 and the connecting piece 16.

[0080] Example 3

[0081] Reference Figure 1 to Figure 7 , which is the third embodiment of the present invention, is different from the previous two embodiments in that: it includes: there are multiple groups of mounting holes 111, and the multiple groups of mounting holes 111 are evenly distributed on the side wall of the support member 11; the guide rod 21 is adapted to the mounting holes 111, and the guide rod 21 is slidably connected to the second rack 22; the second rack 22 is meshed with the outer gear ring 14, so that the rotation of the outer gear ring 14 can drive the second rack 22 to reciprocate along the axial direction of the guide rod 21.

[0082] In this embodiment, the number of mounting holes 111 is multiple groups, and the number of mounting holes 111 is at least three groups; one group of mounting holes 111 is penetrated by the screw member 12 to drive the first rack 13 to move in the horizontal direction, and the remaining mounting holes 111 are distributed in a circumferential array along the outer wall of the support member 11; and the corresponding mounting holes 111 are provided with guide rods 21 inside. In the process, the protrusion 141 always contacts the end of the limit block 15, and the push member 23 pushes the lifting rod 2

[0083] Preferably, the number of mounting holes 111 is four groups, and the remaining three groups of mounting holes 111 are located on the side wall of the support member 11 and are distributed at equal angles; at this time, the three groups of second racks 22 can be driven by the outer ring gear 14 at the same time, and the load driven by the outer ring gear 14 is relatively small, so it is easier to rotate the screw member 12; at the same time, the three groups of second racks 22 correspond to corresponding lifting rods 24; the three groups of lifting rods 24 can form a stable support for the support seat 25, thereby ensuring that the movement of the lifting rods 24 can smoothly push the support seat 25 to move.

[0084] Specifically, when the protrusion 141 begins to conflict with the end of the limit block 15, there is still a certain distance between the pushing member 23 and the lifting rod 24; at this time, in order to realize the pushing member 23 pushing the lifting rod 24 to move, it is necessary to continue to rotate the screw member 12 to drive the outer ring gear 14 to rotate, and drive the second rack 22 to move through the rotation of the outer ring gear 14; during the rotation and movement of the outer ring gear 14, the end of the protrusion 141 and the end of the limit block 15 also remain in a conflicting state, thereby ensuring that the connection between the support member 11 and the connecting member 16 is stable.

[0085] Furthermore, the support member 11 also includes a positioning groove 115 opened on its surface; the support seat 25 includes an annular groove 251 arranged on its end face, and a locking block 252 arranged at the end of the annular groove 251; the locking block 252 is adapted to the positioning groove 115; the locking block 252 can be inserted into the inner side of the positioning groove 115, thereby realizing the limitation of the support seat 25.

[0086] It should be noted that there are multiple groups of positioning grooves 115, and the multiple groups of positioning grooves 115 are located on the upper surface of the support member 11 and distributed in a circular array; and the locking block 252 located at the bottom of the support seat 25 is adapted to the positioning groove 115, and the locking block 252 is inserted into the inner side of the positioning groove 115, thereby limiting the rotation of the support seat 25 along the axial direction of the support member 11.

[0087] Specifically, the support seat 25 coincides with the axis of the support member 11 , and the support seat 25 is a circular plate-shaped structure.

[0088] Furthermore, the support member 11 also includes a positioning column 116 arranged on its surface; the inner wall of the annular groove 251 is in conflict with the side wall of the positioning column 116; an active cavity 1161 is opened inside the positioning column 116; the lifting rod 24 includes an annular plate 241 arranged on its side wall, and a ball 242 arranged on the top of the lifting rod 24; the annular plate 241 is located inside the active cavity 1161, and the top of the lifting rod 24 passes through the active cavity 1161 and extends to its outside.

[0089] It should be noted that the positioning columns 116 are arranged on the upper surface of the support member 11, and the number of the positioning columns 116 corresponds to the number of the lifting rods 24; the inner wall of the annular groove 251 conflicts with the side wall of the positioning columns 116, and the positioning columns 116 can limit the annular groove 251 during its rotation, thereby ensuring that the annular groove 251 can rotate along the axial direction of the support member 11.

[0090] Specifically, the side wall of the lifting rod 24 is provided with an annular plate 241 with a larger diameter, and the annular plate 241 is movable inside the movable cavity 1161, and both ends of the lifting rod 24 pass through the side wall of the support member 11 and extend to its outside; the cooperation between the set annular plate 241 and the movable cavity 1161 can ensure that the lifting rod 24 will not be separated from the positioning column 116.

[0091] Preferably, a ball 242 is further provided on the top of the lifting rod 24, and the ball 242 is rotatable at the top of the lifting rod 24.

[0092] Furthermore, the ball 242 contacts the bottom wall of the annular groove 251 ; the push member 23 is a trapezoidal structure, and the end surface of the push member 23 can contact the bottom surface of the lifting rod 24 ; the movement of the push member 23 can push the lifting rod 24 to move along the axial direction of the positioning column 116 .

[0093] The outer gear ring 14 can rotate to drive the second rack 22 to move along the axial direction of the guide rod 21, and the second rack 22 can drive the pushing member 23 to move at the same time, so that the inclined surface of the pushing member 23 continuously squeezes the bottom surface of the lifting rod 24. As the position where the inclined surface of the pushing member 23 contacts the bottom surface of the lifting rod 24 gradually becomes higher, the distance between the end of the lifting rod 24 penetrating to the outside of the support member 11 gradually increases. At the same time, the ball 242 can contact the inner wall of the annular groove 251. As the pushing member 23 lifts the lifting rod 24 to the highest position, the locking block 252 leaves the inside of the positioning groove 115, and there is a certain gap between the bottom surface of the locking block 252 and the surface of the support member 11. At this time, the bottom surface of the support seat 25 contacts the ball 242, which can save effort in the process of rotating the support seat 25.

[0094] Furthermore, the support seat 25 includes a positioning sleeve 253 disposed inside the annular groove 251 ; the connecting member 16 includes a limiting plate 162 disposed inside thereof, and the positioning sleeve 253 penetrates the limiting plate 162 and extends to the outside thereof.

[0095] In this embodiment, a positioning sleeve 253 is connected to the center of the support seat 25, and the positioning sleeve 253 passes through the limiting plate 162 and extends to its outside. An extension plate is connected to the bottom of the positioning sleeve 253, so that the support seat 25 will not be separated from the connecting member 16. During the movement, the support seat 25 can only move along the axial direction of the support member 11.

[0096] Specifically, when the connecting member 16 is connected to the supporting member 11 , the supporting seat 25 can only move along the axial direction of the supporting member 11 , including being able to rotate or reciprocate along the axial direction of the supporting member 11 .

[0097] Furthermore, the support seat 25 also includes a mounting groove 254 arranged on the surface opposite to the annular groove 251; a robot arm Q is installed inside the mounting groove 254.

[0098] It should be noted that a mounting groove 254 is installed on the upper surface of the support seat 25, and a robot arm Q is installed inside the mounting groove 254 by bolt connection; at this time, the support seat 25 needs to withstand a larger gravity, and the movement of the support seat 25 along the axial direction of the support member 11 is subject to certain restrictions; at the same time, when the locking block 252 is engaged with the positioning groove 115, the support seat 25 cannot be rotated along the axis of the support member 11 at will, thereby realizing the installation and fixation of the robot arm Q.

[0099] During use, when the staff needs to adjust the installation angle of the robot arm Q, in the technical operation of the second embodiment, it is necessary to continue to use the tool to drive the screw member 12 to rotate. The rotation of the screw member 12 can drive the first rack 13 to move in the horizontal direction. The movement of the first rack 13 can drive the outer gear ring 14 to rotate along the axial direction of the support member 11; the rotation of the outer gear ring 14 can drive the second rack 22 to move along the axial direction of the guide rod 21. The movement of the second rack 22 can drive the pushing member 23 arranged at its end to move. With the movement of the second rack 22, the inclined surface of the pushing member 23 continuously contacts and squeezes the bottom surface of the lifting rod 24, so that the distance that the top of the lifting rod 24 passes through the positioning column 116 gradually increases, and the lifting rod 24 is moved during the movement of the ball 242 and the bottom of the support seat 25. The surfaces are in contact with each other, and the lifting rod 24 pushes the support seat 25 to move during the movement, so that the locking block 252 leaves the inner side of the positioning groove 115, thereby releasing the limit on the rotation of the support seat 25 along the axial direction of the support member 11; at this time, the rotating support seat 25 can flexibly drive the robot arm Q to adjust the angle. When the adjustment is completed, the screw member 12 rotates in the opposite direction, so that the lifting rod 24 begins to gradually move toward the inner wall of the support member 11; during the movement, if the locking block 252 contacts the surface of the support member 11, which will limit the reset of the support seat 25, the support seat 25 can be rotated to fine-tune the angle so that the locking block 252 cooperates with one set of positioning grooves 115, and then the screw member 12 can continue to be rotated in the opposite direction until the bottom surface of the annular groove 251 contacts the top surface of the support member 11.
