[0025] 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.
[0026] Example:
[0027] like Figure 1-6 As shown, this embodiment proposes a multi-axis clamping robotic arm based on the production of automotive air compressor valve plates, including a multi-axis robotic arm body 10, on which a mounting rod 20 is provided;
[0028] The mounting rod 20 is provided with two sets of electric grippers 40, and the mounting rod 20 is provided with two sets of moving slots 22. The two sets of electric grippers 40 are respectively disposed in the two sets of moving slots 22. The mounting rod 20 is also provided with a drive assembly 30, which is disposed in the two sets of moving slots 22. The drive assembly 30 cooperates with the two sets of electric grippers 40, so that the two sets of electric grippers 40 slide and adjust their positions in the moving slots 22.
[0029] In this embodiment, when clamping the plate during the production of the automotive air compressor valve plate, the drive assembly 30 first drives the two sets of electric grippers 40 to move on the mounting rod 20 until the two sets of electric grippers 40 are adjusted to a distance that matches the plate. Then, the electric grippers 40 clamp the side of the plate until the two sets of electric grippers 40 clamp the plate simultaneously to complete one clamping. After that, the drive assembly 30 drives the two sets of electric grippers 40 to move towards the plate and perform a second clamping through the relative displacement of the electric grippers 40. Finally, the multi-axis robotic arm body 10 transfers the plate to other processing areas.
[0030] The drive assembly 30 drives two sets of electric grippers 40 to slide bidirectionally within the moving groove 22, which can dynamically adjust the clamping distance according to the size of different valve plates, significantly improving the overall versatility and workpiece compatibility. Moreover, during the first clamping, the electric grippers 40 are adjusted to the appropriate distance to perform basic clamping on the side of the valve plate. Subsequently, the drive assembly 30 drives the two sets of electric grippers 40 to further displace relative to each other for secondary clamping, forming a multi-point progressive clamping, which effectively enhances the uniformity of clamping force distribution and avoids workpiece displacement or slippage. In addition, combined with the multi-degree-of-freedom motion characteristics of the multi-axis robotic arm body 10, it can effectively achieve precise positioning of the valve plate during the grasping, first clamping, second clamping and transfer process, ensuring the posture stability of the workpiece under high-speed handling and complex processing paths.
[0031] Specifically, the multi-axis robotic arm body 10 is provided with a connecting plate 11, and the mounting rod 20 is provided with a connecting frame 21, which is connected to the connecting plate 11 by bolts.
[0032] In this embodiment, the connecting disk 11 is rotatably mounted on the multi-axis robotic arm body 10 and is driven to rotate by the multi-axis robotic arm body 10. The connecting disk 11 serves as the end effector interface of the multi-axis robotic arm body 10 and can drive the mounting rod 20 and the electric gripper 40 to rotate around the axis. Combined with the motion trajectory of the multi-degree-of-freedom robotic arm, it can achieve precise multi-dimensional posture adjustment during valve plate gripping and handling, meeting the stringent requirements of complex processes for workpiece angle positioning.
[0033] Specifically, the drive assembly 30 includes a dual-axis servo motor 31, and two sets of drive screws 32 are connected to the dual-axis servo motor 31. The two sets of drive screws 32 are respectively engaged with two sets of electric grippers 40.
[0034] The two sets of drive screws 32 have opposite thread directions.
[0035] In this embodiment, the combination of the drive screw 32 and the dual-axis servo motor 31 facilitates the displacement adjustment of the two sets of electric grippers 40.
[0036] Specifically, the mounting rod 20 is provided with a mounting groove 25, and a mounting plate 24 is provided between the mounting groove 25 and the moving groove 22;
[0037] The dual-axis servo motor 31 is installed in the mounting slot 25, and the two sets of drive screws 32 are respectively rotatably mounted on the two sets of mounting plates 24.
[0038] Specifically, a limiting groove 23 is provided in the moving groove 22, and the limiting groove 23 has the same length as the moving groove 22;
[0039] The electric gripper 40 is provided with a moving block 42, the moving block 42 is provided with a limiting part 44, the moving block 42 is slidably disposed in the moving groove 22, and the limiting part 44 is slidably disposed in the limiting groove 23.
[0040] In this embodiment, a mounting slot 25 is opened inside the mounting rod 20 and a mounting plate 24 is set. The dual-axis servo motor 31 is built into the mounting slot 25, so that the power source of the drive assembly 30 and the drive screw 32 are integrated in the same axial space, which greatly reduces the lateral dimension of the clamping mechanism and optimizes the space utilization of the end effector of the robotic arm. At the same time, the rigid support of the drive screw 32 by the mounting plate 24 ensures the synchronization and stability of the bidirectional transmission.
[0041] Specifically, a connecting rod 41 is provided between the moving block 42 and the electric gripper 40, and the connecting rod 41 is fixedly connected to the moving block 42 and the electric gripper 40.
[0042] Specifically, the movable block 42 has a threaded hole 43, and the drive screw 32 is threadedly connected to the threaded hole 43.
[0043] In this embodiment, when the electric gripper 40 is moved, the dual-axis servo motor 31 is started, which drives the drive screw 32 to rotate. Through the cooperation between the drive screw 32 and the threaded hole 43, the moving block 42 slides in the moving groove 22.
[0044] Of course, the two sets of drive screws 32 are respectively engaged with the two sets of threaded holes 43. When the two sets of drive screws 32 rotate, they can drive the two sets of electric grippers 40 to move simultaneously toward the center of the mounting rod 20.
[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
