Description

Technical Field

[0001] This utility model relates to the field of coupling production technology, specifically an automated coupling production line. Background Technology

[0002] Couplings are connecting components between pipes and can be used in oilfield production pipes or other media transportation pipelines. Couplings are cylindrical in shape with steps on the inner wall for connection. Currently, the processing of couplings requires multiple steps, each of which requires clamping. When using CNC machine tools, each step corresponds to a processing program. Operators need to select the corresponding processing program according to the processing steps. Moreover, after one step is completed, the workpiece needs to be temporarily stored and then transferred to the machine tool position for the next step, resulting in low overall production efficiency.

[0019] See Figure 1-7This embodiment is an automated production line for couplings, including several CNC machine tools 1 arranged in a straight line. A horizontal track beam 4 is provided above the CNC machine tools 1, and the track beam 4 is parallel to the arrangement direction of the CNC machine tools 1. At least two sets of robotic arms 3 are mounted on the track beam 4, and the robotic arms 3 are slidably connected to the track beam 4. The robotic arms 3 are used to transport workpieces between the CNC machine tools 1. The robotic arm 3 includes a base 31, on which a traveling mechanism is mounted. The traveling mechanism drives the robotic arm 3 to move along the track beam 4. A slide rail is provided on one side of the base 31 in a vertical direction, and a lifting seat 32 is mounted on the slide rail. The lifting seat 32 is connected to a lifting drive mechanism, and a gripping mechanism 35 is mounted at the bottom of the lifting seat 32. The gripping mechanism 35 is used to clamp the couplings. The CNC machine tools 1 are connected to each other and to the robotic arms 3 to achieve automatic control.

[0020] Furthermore, the bottom of the lifting seat 32 is equipped with two sets of gripping mechanisms 35, and the bottom of the lifting seat 32 is equipped with a support rail 36 parallel to the track beam 4. Both sets of gripping mechanisms 35 are slidably connected to the support rail 36. Each end of the support rail 36 is equipped with a set of linear drive mechanisms, and the two sets of linear drive mechanisms are respectively connected to the two sets of gripping mechanisms 35. The linear drive mechanisms are used to adjust the position of the corresponding gripping mechanism 35.

[0021] Furthermore, the linear drive mechanism includes a servo motor C34, the output end of which is equipped with a lead screw 37, which is threadedly connected to the corresponding gripping mechanism 35.

[0022] Furthermore, the walking mechanism includes a rack 5 and a servo motor A310. The servo motor A310 is installed in the base 31, and a gear 39 is installed at the output end of the servo motor A310. The gear 39 is rotatably connected to the base 31. The rack 5 is installed on the top surface of the track beam 4 and is arranged along the entire length of the track beam 4. The rack 5 meshes with the gear 39. The servo motor A310 controls the number of rotations of the gear 39 to precisely control the distance that the robot arm 3 moves on the track beam 4.

[0023] Furthermore, the lifting drive mechanism includes a servo motor B33, which is mounted on the top of the lifting base 32. The output end of the servo motor B33 is equipped with a lead screw 38. A linear guide rail 311 is provided on one side of the lifting base 32. A slider corresponding to the linear guide rail 311 is provided on the base 31. The slider is fixedly connected to the base 31 and slidably connected to the linear guide rail 311. A connecting block is also fixedly mounted on the base 31, and the connecting block is threadedly connected to the lead screw 38.

[0024] Furthermore, a row of guardrails 2 is provided above the CNC machine tool 1, located below the track beam 4. The bottom surface of the guardrails 2 has openings corresponding to each CNC machine tool 1, allowing the robotic arm 3 to pass through. This invention, by providing guardrails 2, prevents the robotic arm 3 from accidentally dropping workpieces during its movement. Falling workpieces are blocked by the guardrails 2, preventing them from falling from a height and damaging the machine tool or injuring the operator.

[0025] The working principle of this utility model is as follows: The system controls the robot arm 3 to pick up the cut tube blank. The robot arm 3 sends the tube blank to the CNC machine tool 1 corresponding to the first process for processing. After the first process is completed, the door of the CNC machine tool 1 is opened. The system controls the robot arm 3 to take out the workpiece from the machine tool and send it to the CNC machine tool 1 corresponding to the second process for processing. In this way, the robot arm 3 transports the workpiece to the corresponding machine tool according to the process until the last process is completed, that is, the finished product is processed. Finally, the robot arm 3 takes out the finished product and places it in the designated storage point.

[0026] In this utility model, the hatch of each CNC machine tool 1 is a sliding door structure with an L-shaped structure. When the hatch is opened, the robot arm 3 enters the processing compartment from the top of the machine tool to perform actions. When the robotic arm 3 performs its actions, the system controls the servo motor A310 to move the robotic arm 3 to the designated position. After the robotic arm 3 reaches the position, it stops. Then, the system controls the servo motor B33 to rotate the lead screw 38. Since the lead screw 38 is threadedly connected to the connecting block of the base 31 and the base 31 is fixed, the lifting seat 32 will move up and down along the slider via the linear guide rail 311. By controlling the action parameters of the servo motor B33, the gripping mechanism 35 reaches the height of the workpiece inside the machine tool. Finally, the gripping mechanism 35 clamps the workpiece from the machine tool, and the servo motor B33 drives the lifting seat 32 to rise back to the high position. At this time, the gripping mechanism 35 carries the workpiece up to above the guardrail 2. Then, the servo motor A310 controls the robotic arm 3 to move to the position of the next process. The servo motor B33 then controls the lifting seat 32 to descend so that the gripping mechanism 35 carries the workpiece into the machine tool. After the machine tool clamps the workpiece, the gripping mechanism 35 releases the workpiece and rises back to the high position, waiting for system instructions.

[0027] This utility model is equipped with multiple robotic arms 3. When there are multiple places on the production line where robotic arms 3 need to perform actions, and one of the robotic arms 3 is performing an action at a certain CNC machine tool 1, in order to save time, the system will automatically control another robotic arm 3 to go to another CNC machine tool 1 or the loading / unloading position to perform the action.

[0028] This invention uses a linear drive mechanism to adjust the distance between the two gripping mechanisms 35, thereby adapting to workpieces of different lengths.

[0029] Specifically, the servo motor C34 drives the lead screw 37 to rotate, which in turn drives the corresponding gripping mechanism 35 to move along the support track 36.

[0030] The system automatically adjusts the distance between the two gripping mechanisms 35 according to the length of the workpiece to be processed, ensuring that the workpiece is gripped by both gripping mechanisms 35 at the same time each time, thereby ensuring stability and preventing accidents caused by the failure of one of the gripping mechanisms 35.
