Abstract
Description
Technical Field
[0001] This utility model relates to the field of robotic arm technology, specifically to a robotic arm that is easy to fix. Background Technology
[0002] In the field of modern industrial production and automation technology, robotic arms, as automated devices capable of simulating human hand movements to grasp, handle, and precisely manipulate materials, have been widely used in various industries such as automobile manufacturing, electronic assembly, logistics warehousing, and medical devices. With the rapid development of intelligent manufacturing, higher requirements are being placed on the ease of installation, stability, and versatility of robotic arms.
[0003] Traditional robotic arms are primarily secured using bolt connections, welding, or flanges. While these methods meet basic securing requirements, they have several shortcomings in practical applications. For example, direct bolt fixing requires precise alignment of the mounting holes, and repeated disassembly and reassembly can easily lead to thread wear, affecting connection strength. Welding provides a strong rigid connection but cannot be adjusted in position; once the installation location is determined, it is difficult to change, and maintenance costs are high. Flange connections, on the other hand, require a high degree of flatness and perpendicularity of the mounting surface, making the installation process cumbersome. Utility Model Content
[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a conveniently fixed robotic arm, which has the advantage of being easy for users to fix, thus solving the problem that robotic arms are inconvenient for users to fix.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveniently fixed robotic arm, comprising:
[0006] A robotic arm, comprising a connecting base, a robotic arm fixedly mounted on the top of the connecting base, a robotic claw fixedly mounted on the side of the robotic arm away from the connecting base, and connecting blocks fixedly connected to the front and rear ends of the bottom of the connecting base;
[0007] A support base, wherein the support base is disposed at the bottom of the connecting base;
[0008] The installation mechanism includes a positioning plate, which is disposed at the front and rear ends of the top of the connecting seat. A drive shaft is fixedly connected to the bottom of the positioning plate. The bottom of the drive shaft passes through the connecting seat and extends into the interior of the connecting block, where a winding drum is fixedly connected. Connecting belts are fixedly connected to both sides of the winding drum. A connecting plate is fixedly connected to the outer side of the connecting belt, and a positioning rod is fixedly connected to the outer side of the connecting plate.
[0009] In a preferred embodiment of this utility model, the support base includes a fixed base, and each of the four corners of the top of the fixed base is provided with an electric telescopic rod. The bottom of the electric telescopic rod extends into the interior of the fixed base and is fixedly connected to the interior of the fixed base. A flange is fixedly connected to the top of the electric telescopic rod, and a lifting plate is fixedly connected to the top of the flange by bolts and nuts. The bottom of the connecting block passes through the lifting plate and extends into the interior of the lifting plate. The side of the positioning rod away from the connecting plate passes through the connecting block and extends into the interior of the lifting plate.
[0010] As a preferred embodiment of this utility model, positioning bearings are fixedly connected to the top and bottom of the surface of the transmission shaft, and the outer ring of the positioning bearing is fixedly connected to the interior of the connecting block on the side near the connecting block.
[0011] As a preferred embodiment of this utility model, a return spring is fixedly connected to the top and bottom of the inner side of the connecting plate, and a vertical plate is fixedly connected to the side of the return spring away from the connecting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model achieves rapid positioning and fixing of the robotic arm by setting up an installation mechanism. Compared with the traditional bolt connection method, it does not require aligning the holes one by one, which greatly shortens the installation time. At the same time, the horizontal insertion of the positioning rod forms a mechanical engagement, which can effectively resist lateral forces and vibrations and improve the connection stability.
[0016] 2. By setting up a support base, this utility model allows the robot arm to adjust its height in real time according to the installation environment or operation requirements, achieving adaptive height adjustment. Furthermore, the bolt connection between the lifting plate and the flange, combined with the mechanical engagement of the positioning rod, forms a double connection structure, which ensures connection strength and facilitates quick disassembly. At the same time, the electric telescopic rods distributed at the four corners can evenly bear the weight of the robot arm, avoiding structural deformation caused by single-point force.
[0017] 3. By setting a positioning bearing, this utility model can provide radial and axial support for the drive shaft, reduce shaking and offset during rotation, ensure synchronous and smooth rotation of the winding drum, and at the same time, the rolling friction of the bearing replaces the sliding friction of the traditional bushing, which greatly reduces wear between mechanical parts, reduces operating resistance, and extends the equipment maintenance cycle.

[0023] 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.
[0024] like Figures 1 to 4 As shown, the present invention provides a conveniently fixed robotic arm, comprising:
[0025] The robotic arm 1 includes a connecting base 101, a robotic arm 102 is fixedly mounted on the top of the connecting base 101, a robotic claw 103 is fixedly mounted on the side of the robotic arm 102 away from the connecting base 101, and connecting blocks 104 are fixedly connected to the front and rear ends of the bottom of the connecting base 101.
[0026] Support base 2 is located at the bottom of connecting base 101;
[0027] The installation mechanism 3 includes a positioning plate 31, which is located at the front and rear ends of the top of the connecting seat 101. A drive shaft 32 is fixedly connected to the bottom of the positioning plate 31. The bottom of the drive shaft 32 passes through the connecting seat 101 and extends into the interior of the connecting block 104, where a winding drum 33 is fixedly connected. Connecting belts 34 are fixedly connected to both sides of the winding drum 33. A connecting plate 35 is fixedly connected to the outer side of the connecting belt 34, and a positioning rod 36 is fixedly connected to the outer side of the connecting plate 35.
[0028] refer to Figure 4 The support base 2 includes a fixed base 21. Each of the four corners of the top of the fixed base 21 is provided with an electric telescopic rod 22. The bottom of the electric telescopic rod 22 extends into the interior of the fixed base 21 and is fixedly connected to the interior of the fixed base 21. The top of the electric telescopic rod 22 is fixedly connected to a flange 23. The top of the flange 23 is fixedly connected to a lifting plate 24 by bolts and nuts. The bottom of the connecting block 104 passes through the lifting plate 24 and extends into the interior of the lifting plate 24. The positioning rod 36 passes through the connecting block 104 and extends into the interior of the lifting plate 24 on the side away from the connecting plate 35.
[0029] As a technical optimization of this utility model, by setting a support base 2, the robot arm 1 can adjust its height in real time according to the installation environment or operation requirements, so as to achieve height self-adaptive adjustment. The bolt connection between the lifting plate 24 and the flange 23, combined with the mechanical engagement of the positioning rod 36, forms a double connection structure, which not only ensures the connection strength but also facilitates quick disassembly. At the same time, the electric telescopic rods 22 distributed at the four corners can evenly bear the weight of the robot arm 1, avoiding structural deformation caused by single-point force.
[0030] refer to Figure 3 Positioning bearings 4 are fixedly connected to the top and bottom of the surface of the drive shaft 32. The outer ring of the positioning bearing 4 is fixedly connected to the inside of the connecting block 104 on the side near the connecting block 104.
[0031] As a technical optimization of this utility model, by setting the positioning bearing 4, radial and axial support can be provided for the transmission shaft 32, reducing shaking and offset during rotation, ensuring synchronous and smooth rotation of the winding drum 33, and at the same time, the rolling friction of the bearing replaces the sliding friction of the traditional bushing, greatly reducing wear between mechanical parts, reducing operating resistance, and extending the equipment maintenance cycle.
[0032] refer to Figure 3 A return spring 5 is fixedly connected to the top and bottom of the inner side of the connecting plate 35. A vertical plate 6 is fixedly connected to the side of the return spring 5 away from the connecting plate 35. The side of the vertical plate 6 close to the connecting block 104 is fixedly connected to the inside of the connecting block 104.
[0033] As a technical optimization of this utility model, by setting a reset spring 5 and a vertical plate 6, an elastic linkage structure is formed, which plays a key role in the process of the positioning rod 36 being inserted into the lifting plate 24. When the rotating positioning disk 31 drives the winding drum 33 to tighten the connecting belt 34, the connecting plate 35 overcomes the elastic force of the reset spring 5 and slides outward, driving the positioning rod 36 to be accurately inserted into the preset positioning hole of the lifting plate 24.
[0034] refer to Figure 3 The top and bottom of the connecting plate 35 are fixedly connected to sliders 7, and the top and bottom of the inner wall of the connecting block 104 are provided with grooves 8, and the sliders 7 are slidably connected to the grooves 8.
[0035] As a technical optimization of this utility model, by setting the slider 7 and the slide groove 8, the movement direction of the connecting plate 35 is strictly limited, ensuring that the positioning rod 36 does not shift or tilt laterally during the extension and retraction process, accurately inserting or withdrawing from the mounting hole, and improving the installation success rate. At the same time, the mating surface of the slide groove 8 and the slider 7 bears the lateral force on the positioning rod 36, reducing the stress load on the connecting belt 34 and the transmission shaft 32, and avoiding damage to the components.
[0036] refer to Figure 4 The four corners of the top of the fixed base 21 are provided with positioning grooves 9, and the inside of the positioning grooves 9 is fixedly connected to the surface of the electric telescopic rod 22.
[0037] As a technical optimization of this utility model, by setting the positioning groove 9, a precise installation positioning benchmark can be provided for the electric telescopic rod 22, ensuring the verticality and spacing consistency of the four corner telescopic rods, avoiding the tilting of the robot arm 1 or uneven load caused by installation deviation, which is suitable for high-precision operation scenarios.
[0038] The working principle and usage process of this utility model are as follows: First, the fixed seat 21 of the support base 2 is fixed to the installation foundation using expansion bolts or similar methods. The positioning grooves 9 at the four corners of the top of the fixed seat 21 provide a precise installation reference for the electric telescopic rod 22, ensuring that the electric telescopic rod 22 is vertical and the spacing is consistent. Then, by controlling the electric telescopic rod 22, the flange 23 at its top drives the lifting plate 24 to move up and down. After adjusting the lifting plate 24 to a suitable height, the operator rotates the positioning discs 31 at the front and rear ends of the top of the connecting seat 101. The drive shaft 32 fixed at the bottom of the positioning disc 31 rotates synchronously with the positioning disc 31. The outer rings of the positioning bearings 4 at the top and bottom of the drive shaft 32 are fixed to the inside of the connecting block 104, providing stable radial and axial support for the drive shaft 32 and ensuring that it does not shake or deviate during rotation. The winding drum 33 at the bottom of the drive shaft 32 winds the connecting belt 34 as the drive shaft 32 rotates. When the connecting belt 34 tightens, it pulls the outer connecting plate 35 inward to retract into the connecting block 104. Inside the lifting plate 24, the connecting seat 101 of the robot arm 1 is placed on top of the lifting plate 24, and the connecting blocks 104 at the front and rear ends of the bottom of the connecting seat 101 are aligned with the corresponding through holes on the lifting plate 24 and inserted into them. At this time, the connecting blocks 104 penetrate the lifting plate 24 and extend into it, providing a basic positioning for subsequent fixation. The elastic extension of the returning spring 5 drives the connecting plate 35 to move outward. The positioning rod 36 on the outside of the connecting plate 35 moves outward synchronously with the connecting plate 35, gradually penetrating the connecting block 104 and inserting into the preset positioning hole inside the lifting plate 24 until the positioning rod 36 is fully inserted. At this time, the elastic pre-tightening force of the returning spring 5 pushes the connecting plate 35 to make the positioning rod 36 fit tightly with the positioning hole of the lifting plate 24, forming a mechanical locking fixation. When it is necessary to adjust the height of the robot arm 1, the electric telescopic rods 22 at the four corners of the top of the fixed seat 21 are controlled to extend and retract synchronously. The flange 23 at the top of the electric telescopic rod 22 drives the lifting plate 24 and the robot arm 1 above it to move up and down as a whole.
[0039] In summary, this conveniently fixed robotic arm, through the installation mechanism 3, achieves rapid positioning and fixation of the robotic arm 1. Compared with the traditional bolt connection method, it eliminates the need to align the holes one by one, significantly shortening the installation time. At the same time, the positioning rod 36 is inserted laterally to form a mechanical engagement, which can effectively resist lateral forces and vibrations, improving connection stability.
