Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically to a mounting base for a robotic arm. Background Technology

[0002] With the rapid development of modern manufacturing towards automation and intelligence, robotic arms are increasingly widely used in numerous industrial production scenarios. Robotic arms can perform high-precision cutting tasks and require precise and stable installation in specific locations to ensure they can complete operations such as grasping, handling, and assembly according to preset trajectories and task requirements. The mounting base, as a key component connecting the robotic arm to the mounting surface (such as a workshop floor or workbench), bears the overall weight of the robotic arm and withstands various forces generated during operation. Its performance directly affects the accuracy, stability, and service life of the robotic arm.

[0003] In the prior art, a Chinese patent document with publication number CN222844155U and publication date of May 9, 2025 was proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a mounting base for a robotic arm on an automobile production line, including a base body, an annular groove formed in the upper part of the inner cavity of the base body, a bearing fixedly mounted at the position of the annular groove, a rotator fixedly mounted at the position of the inner ring of the bearing, the rotator including a vertical tube, a bearing ring plate and an arc-shaped guide head, the vertical tube being inserted and fixed on the inner ring of the bearing, the top of the vertical tube being integrally connected to the bearing ring plate and the arc-shaped guide head, the bearing ring plate being in contact with the top ring of the base body, and the arc-shaped guide head being facing upward.

[0004] To address the issue of quick installation of the robotic arm and its base, existing technology employs a method where the robotic arm presses against a rotator to rotate and move, thereby aligning and securing the mounting holes. This allows for a simpler and faster installation of the robotic arm onto the mounting base. However, because robotic arms require strict stability in long-term, complex, and diverse working environments, this technology does not adequately consider this aspect in its overall design. Consequently, it lacks sufficient stability, leading to wobbling during operation and impacting the accuracy of its operation. Utility Model Content

[0005] The purpose of this invention is to provide a mounting base for a robotic arm to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A mounting base for a robotic arm includes a robotic arm, a base detachably mounted on the lower part of the robotic arm, a support fixedly mounted on the top of the base, and a locking seat fixedly mounted on the bottom end of the robotic arm, the locking seat engaging inside the support seat.

[0008] The base is provided with a stabilizing unit at its top. The stabilizing unit includes a support column fixedly installed at the top of the base. The other end of the support column is fixedly installed on the bottom of the support base. Reinforcing ribs are fixedly installed around the support column to enhance its supporting force.

[0009] A further improvement of this utility model is that: a storage cavity is provided around the support column on one side of the reinforcing rib, a locking hole is provided on the bottom inner side of the storage cavity, and fixed feet are rotatably installed on the bottom sides of the storage cavity. Four sets of fixed feet are provided, which can increase the contact area between the base and the ground and further improve the stability of the base.

[0010] A further improvement of this utility model is that a limiting block is fixedly installed on one of the inner top sides of the fixed foot, and a locking rod is movably inserted into the top of the fixed foot. The other end of the locking rod passes through the limiting block and extends into the locking hole, and the locking rod can lock the opening of the fixed foot.

[0011] A further improvement of this utility model is that: the top of the fixing foot is threaded with a locking bolt above the locking rod, and a positioning hole is provided at the front end of the fixing foot.

[0012] A further improvement of this utility model is that: a cavity is formed around the support column above the storage cavity, a through hole is formed at the bottom of the cavity, the through hole extends to the top of the storage cavity, and a fixed vertical rod is fixedly installed at the top of the cavity.

[0013] A further improvement of this utility model is that a positioning rod is movably sleeved on the outer surface of the bottom end of the fixed vertical rod, and the other end of the positioning rod is movably inserted into the inside of the positioning hole.

[0014] A further improvement of this utility model is that: a toggle plate is fixedly sleeved on the outer surface of the top end of the positioning rod, and a return spring is movably sleeved on the outer surface of the fixed vertical rod. One end of the return spring is fixedly installed at the top end of the cavity, and the other end of the return spring is fixedly installed at the top of the positioning rod.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a mounting base for a robotic arm. By setting four sets of fixed feet, it is spread out around the support column. At this time, the locking rod is pushed so that its other end is inserted into the locking hole. Then, by rotating the locking bolt, its other end abuts against the top of the locking rod, thus locking the position of the fixed feet. The fixed feet increase the contact area between the base and the ground, thereby improving the stability of the base and further improving the accuracy of the mechanical parts.

[0017] 2. This utility model provides a mounting base for a robotic arm. By setting a storage cavity and lifting the actuating plate upwards, the positioning rod slides upwards on the outer surface of the fixed vertical rod and compresses the return spring. At this time, the locking rod can be released, and the fixed foot can be rotated and hidden inside the storage cavity. Then, the actuating plate is released, so that the other end of the positioning rod is inserted into the positioning hole to fix the storage of the fixed foot, thereby reducing the volume and promoting the convenience of transportation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figure 1-5 As shown, this utility model provides a mounting base for a robotic arm, including a robotic arm 1. A base 2 is detachably mounted below the robotic arm 1. A support 3 is fixedly mounted on the top of the base 2. A locking seat 4 is fixedly mounted on the bottom end of the robotic arm 1, and the locking seat 4 is locked into the inside of the support 3. A stabilizing unit is provided on the top of the base 2. The stabilizing unit includes a support column 21 fixedly mounted on the top of the base 2. The other end of the support column 21 is fixedly mounted on the bottom end of the support 3. Reinforcing elements are fixedly mounted on all four sides of the support column 21. The reinforcing rib 22 and the support column 21 are provided with a storage cavity 23 on one side of the reinforcing rib 22. The bottom inner side of the storage cavity 23 is provided with a locking hole 24. Fixed feet 25 are rotatably installed on the bottom sides of the storage cavity 23. A limit block 26 is fixedly installed on one inner top of the fixed foot 25. A locking rod 27 is movably inserted into the top of the fixed foot 25. The other end of the locking rod 27 passes through the limit block 26 and extends into the inside of the locking hole 24. A locking bolt 251 is threadedly connected to the top of the fixed foot 25 above the locking rod 27.

[0027] Furthermore, by setting four sets of fixed feet 25, which are spread out around the support column 21, and by pushing the locking rod 27 so that its other end is inserted into the locking hole 24, and by rotating the locking bolt 251 so that its other end abuts against the top of the locking rod 27, the fixed feet 25 are locked in position. The fixed feet 25 increase the contact area between the base 2 and the ground, thus promoting the stability of the base 2.

[0028] Example 2

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a positioning hole 28 is provided at the front end of the fixed foot 25, and a cavity 29 is provided around the support column 21 above the storage cavity 23. A through hole is provided at the bottom of the cavity 29, extending to the top of the storage cavity 23. A fixed vertical rod 210 is fixedly installed at the top of the cavity 29. A positioning rod 211 is movably sleeved on the outer surface of the bottom end of the fixed vertical rod 210. The other end of the positioning rod 211 is movably inserted into the positioning hole 28. A toggle plate 212 is fixedly sleeved on the outer surface of the top end of the positioning rod 211. A return spring 213 is movably sleeved on the outer surface of the fixed vertical rod 210. One end of the return spring 213 is fixedly installed at the top of the cavity 29, and the other end of the return spring 213 is fixedly installed on the top of the positioning rod 211.

[0030] Furthermore, by lifting the toggle plate 212 upwards, the positioning rod 211 slides upwards on the outer surface of the fixed vertical rod 210, and the return spring 213 is compressed. At this time, the locking rod 27 can be released, and the fixed foot 25 can be rotated and hidden inside the storage cavity 23. Then, the toggle plate 212 is released, so that the other end of the positioning rod 211 is inserted into the inside of the positioning hole 28 to fix the storage of the fixed foot 25, thereby reducing the volume and facilitating transportation.

[0031] The working principle of the mounting base for this robotic arm will be explained in detail below.

[0032] like Figure 1-5 As shown, in use, the base 2 is placed in the desired position, and the robotic arm 1 is installed on top of the base 2. The fixed feet 25 inside the storage cavity 23 are then removed and spread out around the support column 21. The fixed feet 25 increase the contact area between the base 2 and the ground, promoting the stability of the base 2. By pushing the locking rod 27, its other end is inserted into the locking hole 24. Then, by rotating the locking bolt 251, its other end abuts against the top of the locking rod 27, locking the fixed feet 25 in position. When not in use, by lifting the toggle plate 212, the positioning rod 211 slides upward on the outer surface of the fixed vertical rod 210 and compresses the return spring 213, which releases the locking rod 27. The fixed feet 25 are then rotated and hidden inside the storage cavity 23. The toggle plate 212 is then released, allowing the other end of the positioning rod 211 to be inserted into the positioning hole 28, fixing the storage of the fixed feet 25. This reduces the volume and facilitates transportation.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
