Description

Technical Field

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

[0002] A robotic arm is an automated device. In machining, robotic arms are typically used to grip and transport raw materials to machine tools. The robotic arm uses control circuits to control the movement of moving elements to achieve the purpose of gripping workpieces.

[0003] Existing robotic arms typically consist of a basic frame, actuators, drive mechanisms, and control systems. Traditional robotic arms have a highly integrated structural design, with tightly connected components that are difficult to disassemble. During disassembly, assembly, maintenance, and repair, it is difficult for workers to operate on internal components, especially those in hidden or hard-to-reach locations. This makes maintenance extremely difficult, not only wasting a lot of time and effort but also potentially affecting the lifespan of the robotic arm due to the inability to perform comprehensive and meticulous maintenance on internal components. Utility Model Content

[0004] The purpose of this invention is to provide a robotic arm for machining to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A connecting block is fixed to the end of the main combined arm near the secondary combined arm, and a fastening bolt is provided between the connecting block and the end of the secondary combined arm.

[0007] Preferably, the bottom of the rotating seat is provided with a fixed seat, the end of the auxiliary combined arm and the outer wall of the connecting block are provided with mounting grooves, the mounting grooves are provided with threaded holes, the mounting grooves are provided with pads, and the fastening bolts pass through the pads and are threaded into the threaded holes.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] An intermediate motion arm, consisting of a main assembly arm and a secondary assembly arm, is installed between the support arm and the rotating arm. By disassembling the main assembly arm and the secondary assembly arm, the main body of the robotic arm can be divided into two parts that can be directly separated.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] This utility model provides, for example Figure 1 - Figure 4 The mechanical arm for machining shown includes a rotating base 2, with a fixed base 1 at the bottom of the rotating base 2. The fixed base 1 is fixedly connected to the working surface by bolts, and the fixed base 1 fixes the rotating base 2 to prevent the bottom of the rotating base 2 from shaking. The rotating base 2 is mainly driven by a flat motor (not shown in the figure). A support arm 3 is connected to the top output shaft of the rotating base 2. The output shaft of the flat motor drives the support arm 3 to rotate, so that the support arm 3 drives the entire mechanical arm structure to rotate. The direction is adjusted during the rotation. An intermediate action arm 5 is connected to the extension end of the support arm 3. A rotating arm 8 is connected to the extension end of the intermediate action arm 5. A gripper 12 is provided at the end of the rotating arm 8. The intermediate action arm 5 includes a main combination arm 51 and a secondary combination arm 52. A connecting block 55 is fixed to the end of the main combination arm 51 near the secondary combination arm 52. A fastening bolt 54 is provided between the connecting block 55 and the end of the secondary combination arm 52.

[0023] A connecting seat 9 is bolted to the end of the rotating arm 8. A connecting arm 10 is connected to one side of the connecting seat 9. A bearing seat 11 is provided at the end of the connecting arm 10. The gripper 12 is connected to the bearing seat 11.

[0024] In this embodiment, as Figure 1As shown, a first drive motor 4 is fixed to the top of the support arm 3, a secondary mounting base 521 is provided at one end of the secondary combined arm 52, the output shaft of the first drive motor 4 is fixedly connected to the secondary mounting base 521, a mounting shell 7 is fixed to one end of the rotating arm 8, a second drive motor 6 is fixed to the bottom of the mounting shell 7, a main mounting base 511 is provided at the end of the main combined arm 51, and the output shaft of the second drive motor 6 is fixedly connected to the main mounting base 511. When the first drive motor 4 is started, the output shaft of the first drive motor 4 can rotate in both directions to drive the intermediate moving arm 5 to swing. During the swinging process of the intermediate moving arm 5, the second drive motor 6 and the mounting shell 7 move simultaneously. At the same time, while the output shaft of the second drive motor 6 rotates, the second drive motor 6, the mounting shell 7 and the rotating arm 8 move simultaneously and swing around the output shaft of the second drive motor 6, thereby realizing the swinging action of the rotating arm 8.

[0025] like Figure 3 and Figure 4 As shown, mounting grooves 57 are provided at the end of the auxiliary combined arm 52 and on the outer wall of the connecting block 55. Threaded holes 56 are provided in the mounting grooves 57. A pad 53 is fitted to one side of the threaded hole 56 in the mounting grooves 57. Fastening bolts 54 pass through the pad 53 and are threaded into the threaded hole 56. Holes are also provided on the surface of the pad 53, with the same diameter as the threaded hole 56. During the assembly of the main combined arm 51 and the auxiliary combined arm 52, the pad 53 is first placed in the mounting groove 57, and then the fastening bolts 54 pass through the pad 53 and are threaded into the threaded hole 56. The fastening bolts 54 fix the main combined arm 51 and the auxiliary combined arm 52 together.

[0026] During the rotation of the support arm 3, the intermediate moving arm 5 is driven to rotate. At the same time, the intermediate moving arm 5 swings under the drive of the first drive motor 4. The swinging of the intermediate moving arm 5 can drive the second drive motor 6. The second drive motor 6 drives the mounting shell 7. The mounting shell 7 is equipped with a servo motor (not shown in the figure). The output shaft of the servo motor drives the rotating arm 8 to rotate. The rotating arm 8 drives the connecting seat 9, connecting arm 10, shaft seat 11 and gripper 12 to rotate synchronously, thereby adjusting the direction of the gripper 12 to facilitate the gripping of the workpiece.

[0027] like Figure 2 and Figure 5As shown, the outer wall of the mounting shell 7 is provided with a protective component 13. The protective component 13 includes a shell 131. Multiple connecting rods 132 are fixed to the outer wall of the shell 131. An airbag 133 is connected to the end of the connecting rod 132. An air inlet pipe 134 is provided on the outer wall of the airbag 133. An inflation / deflation valve core is connected to the end of the air inlet pipe 134. By inflating the air inlet pipe 134 with an external air pump, the airbag 133 can be inflated, thus making the airbag 133 in an inflated state. The airbag 133 has a strong protective effect. It is worth noting that the inner wall of the shell 131 has a groove 135. The outer side of the mounting shell 7 is placed into the groove 135, which can fit tightly with the shell 131. The shell 131 can be fixed with glue, so that the shell 131 can be fixed to the outer wall of the mounting shell 7.

[0028] Specifically, the protective component 13 can isolate the mounting shell 7 from external objects. During the rotation of the support arm 3 and the swinging of the intermediate action arm 5, the protective component 13 can reduce the damage caused by the mounting shell 7 colliding with external objects or personnel, thereby protecting the mounting shell 7 and personnel.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
