[0002] In the automotive manufacturing supply chain, stamping is a core process in the production of body parts. Its efficiency and precision directly determine the overall quality of the vehicle. Automotive stamped parts are characterized by large dimensional variations, high material hardness, and stringent surface quality requirements, which places extremely high demands on the automation level of production equipment. As a key piece of equipment in the stamping production line for grasping, transferring, and stacking workpieces, the performance of a single robotic arm directly affects the continuity and stability of the stamping process.

[0003] Existing single-machine robotic arms still have many limitations in practical applications. Some robotic arms have fixed and simple structures, limited working range, and are difficult to adapt to the flexible operation requirements of different scenarios, which reduces the efficiency of the device. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the limitations of existing single-machine robotic arms in practical applications, such as fixed and simple structures, limited operating range, difficulty in adapting to flexible operation requirements in different scenarios, and reduced efficiency of the device. Therefore, this invention proposes a single-machine robotic arm.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a single-machine robotic arm, including a base, a rectangular groove on the surface of the base, a robotic arm body on the top of the rectangular groove, an easily replaceable device on the upper surface of the robotic arm body, the easily replaceable device including a mounting block, the mounting block being fixedly connected to the upper surface of the robotic arm body, a limiting groove on the bottom of the mounting block, a spring being fixedly connected to one side of the limiting groove, a limiting block being fixedly connected to one side of the spring, the limiting block being movably connected to the inside of the limiting groove, a fixing groove on the surface of the limiting block, a connecting block being engaged inside the limiting groove, a mounting plate being fixedly connected to the bottom of the connecting block, and a suction cup being fixedly connected to the bottom of the mounting plate.

[0006] Furthermore, a fixing block is fixedly connected to one side of the connecting block, the fixing block is snapped into the inside of the fixing groove, and a positioning hole is provided on one side of the mounting block.

[0007] Furthermore, a positioning rod is movably connected inside the positioning hole, and one side of the positioning rod is fixedly connected to one side of the limiting block.

[0008] Furthermore, the surface of the rectangular groove is provided with an angle adjustment device, which includes a movable block that is movably connected to the inside of the rectangular groove, and a rotating rod is rotatably connected to the top of the movable block.

[0009] Furthermore, a chassis is fixedly connected to the top of the rotating rod, a turbine is fixedly connected to the surface of the rotating rod, a worm gear is meshed with one side of the turbine, a first motor is provided on one side of the worm gear, and the output end of the first motor is fixedly connected to one side of the worm gear.

[0010] Furthermore, a protective frame is provided on one side of the first motor, the protective frame is fixedly connected to one side of the movable block, and sound-absorbing cotton is fixedly connected to the upper inside of the protective frame.

[0011] Furthermore, springs are fixedly connected to both sides of the inner side of the protective frame, a threaded rod is provided inside the rectangular groove, the movable block is threadedly connected to the surface of the threaded rod, a second motor is provided on one side of the threaded rod, and the output end of the second motor is fixedly connected to one side of the threaded rod.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting an easy-to-replace device, when the clamping tool is changed according to different objects, the positioning rod can be pulled backward inside the positioning hole. At the same time, the spring can drive the limiting block to move inside the limiting groove, thereby removing the limiting of the fixing block inside the fixing groove. Then, the connecting block can be pulled out from the limiting groove on the surface of the mounting block for quick replacement. Different working scenarios have significantly different requirements for end effectors. Grabbing heavy metal parts requires high-strength mechanical claws, handling light items such as cardboard boxes is suitable for vacuum suction cups, and assembling precision electronic components requires special clamping tools. The easy-to-replace device allows for the replacement of consumable parts individually without replacing the entire end effector assembly, which improves the convenience of the device during use.

[0014] 2. In this utility model, by setting an angle adjustment device, a second motor drives a threaded rod to rotate, which in turn moves the movable block left and right, thereby moving the robotic arm body left and right. The output of the first motor drives a worm gear, which in turn drives a turbine, which in turn rotates a rotating rod, thus allowing the robotic arm body to adjust its angle in all directions. During use, a protective frame provides initial protection for the second motor at the bottom of the robotic arm body. Simultaneously, springs and sound-absorbing cotton reduce noise and buffer the motor. Traditional robotic arms often require multiple rotations and extensions to indirectly achieve complex angle or positional tasks, resulting in long and time-consuming movement paths. The angle adjustment device and forward / backward movement function reduce redundant movements. Angle adjustment allows the actuator to align with the work surface in one step, while forward / backward movement shortens the distance to the target, improving the device's efficiency.

[0022] Please see Figure 1-5This utility model provides a technical solution: a single-machine robotic arm, including a base 1, a rectangular groove 2 is provided on the surface of the base 1, a robotic arm body 3 is provided on the top of the rectangular groove 2, and an easy-to-replace device 4 is provided on the upper surface of the robotic arm body 3.

[0023] The following section will explain the specific settings and functions of its easy-to-replace device 4 and angle adjustment device 5.

[0024] In this embodiment: the replaceable device 4 includes a mounting block 41, which is fixedly connected to the upper surface of the robotic arm body 3. A limiting groove 42 is formed at the bottom of the mounting block 41. A spring 43 is fixedly connected to one side of the inner side of the limiting groove 42. A limiting block 44 is fixedly connected to one side of the spring 43. A fixing groove 45 is formed on the surface of the limiting block 44. A connecting block 46 is snapped into the inner side of the limiting groove 42. A mounting plate 47 is fixedly connected to the bottom of the connecting block 46. A suction cup 48 is fixedly connected to the bottom of the mounting plate 47.

[0025] Specifically, a fixing block 49 is fixedly connected to one side of the connecting block 46, and the fixing block 49 is snapped into the inside of the fixing groove 45. A positioning hole 410 is provided on one side of the mounting block 41.

[0026] Specifically, a positioning rod 411 is movably connected inside the positioning hole 410, and one side of the positioning rod 411 is fixedly connected to one side of the limiting block 44.

[0027] The effect achieved by the above components is as follows: by setting up the easy replacement device 4, the positioning rod 411 can be pulled backward inside the positioning hole 410. At the same time, the spring 43 can drive the limiting block 44 to move inside the limiting groove 42, thereby removing the limiting of the fixing block 49 inside the fixing groove 45. Then, the connecting block 46 can be pulled out from the limiting groove 42 on the surface of the mounting block 41 for quick replacement. Different operating scenarios have significantly different requirements for the end effector. This device can increase the scope of use of the device and improve its practicality.

[0028] Specifically, the surface of the rectangular groove 2 is provided with an angle adjustment device 5, which includes a movable block 51. The movable block 51 is movably connected to the inside of the rectangular groove 2, and a rotating rod 52 is rotatably connected to the top of the movable block 51.

[0029] Specifically, a chassis 53 is fixedly connected to the top of the rotating rod 52, a turbine 54 is fixedly connected to the surface of the rotating rod 52, a worm gear 55 is meshed with one side of the turbine 54, and a first motor 56 is provided on one side of the worm gear 55.

[0030] Specifically, a protective frame 57 is provided on one side of the first motor 56. The protective frame 57 is fixedly connected to one side of the movable block 51. Sound-absorbing cotton 58 is fixedly connected to the upper inside of the protective frame 57.

[0031] Specifically, springs 59 are fixedly connected to both sides of the inner side of the protective frame 57, a threaded rod 511 is provided inside the rectangular groove 2, the movable block 51 is threadedly connected to the surface of the threaded rod 511, and a second motor 510 is provided on one side of the threaded rod 511.

[0032] The effect achieved by the above components is as follows: by adding the angle adjustment device 5, the second motor drives the threaded rod 511 to rotate, which in turn drives the movable block 51 to move left and right, thereby causing the mechanical arm body 3 to move left and right. The output end of the first motor 56 drives the worm gear 55 to rotate, which in turn drives the turbine 54 to rotate, thereby driving the rotating rod to rotate, thus enabling the mechanical arm body 3 to perform omnidirectional angle adjustment, improving the flexibility of the device and increasing the convenience of the device in use.

[0033] Working principle:

[0034] By setting up the easy-change device 4, when the clamping tool is changed according to different objects, the positioning rod 411 can be pulled backward inside the positioning hole 410. At the same time, the spring 43 can drive the limiting block 44 to move inside the limiting groove 42, thereby removing the limiting of the fixing block 49 inside the fixing groove 45. Then, the connecting block 46 can be pulled out from the limiting groove 42 on the surface of the mounting block 41 for quick replacement. Different working scenarios have significantly different requirements for end effectors. Grabbing heavy metal parts requires high-strength mechanical claws, handling light items such as cardboard boxes is suitable for vacuum suction cups 48, and assembling precision electronic components requires special clamping tools. The easy-change device 4 allows for the replacement of consumable parts individually without replacing the entire end effector assembly, which improves the convenience of the device during use.

[0035] Then, by setting the angle adjustment device 5, the threaded rod 511 is driven by the second motor to rotate. During the rotation, the movable block 51 moves left and right, thereby moving the robotic arm body 3 left and right. The output end of the first motor 56 drives the worm gear 55 to rotate, which in turn drives the turbine 54 to rotate, thereby driving the rotating rod to rotate, thus enabling the robotic arm body 3 to perform omnidirectional angle adjustment. During use, the second motor 510 at the bottom of the robotic arm body 3 is initially protected by the protective frame 57. At the same time, the second spring 59 and the sound-absorbing cotton 58 can achieve noise reduction and buffering. When traditional robotic arms complete complex angle or position operations, they often need to indirectly achieve this through multiple rotation and extension combinations, which is a long and time-consuming action path. The angle adjustment device 5 and the forward and backward movement function can reduce redundant actions. Angle adjustment allows the actuator to be aligned with the work surface in one step, and forward and backward movement shortens the distance to the target, improving the efficiency of the device.
