Description

Technical Field

[0002] Robotic gripper mechanisms are used to grasp and hold materials in the mechanical manufacturing process. However, existing gripper mechanisms typically lack the ability to rotate the material, and robotic arms can usually only rotate the material in one direction. This results in a limited processing area and low processing efficiency when the material is gripped and processed by the robotic arm. Therefore, this paper studies and improves existing structures and their shortcomings to provide a robotic arm-assisted gripper mechanism, aiming to achieve a more practical and valuable solution.

[0026] As attached Figure 1 To be continued Figure 6 As shown:

[0027] This utility model provides a robotic arm-assisted gripping mechanism, including a main housing 1. A connecting housing 2 is fixedly installed on one side of the main housing 1 by fasteners. Two sets of main and auxiliary grippers 3 are symmetrically slidably connected on one side of the connecting housing 2. The inner side of each set of main and auxiliary grippers 3 is provided with a cavity. A drive shaft 4 is rotatably connected to the adjacent side of each set of main and auxiliary grippers 3. A secondary gripper 5 is fixedly installed on one end of each set of drive shafts 4.

[0028] One end of the drive shaft 4 passes through the inner side of the cavity and is fixedly connected to a gear 6 on the same axis. A rack 7 is slidably connected to the bottom side of the inner wall of the cavity. The rack 7 meshes with the gear 6, which can drive the drive shaft 4 and the secondary gripper 5 to rotate flexibly.

[0029] A slider is fixedly connected to the bottom side of the rack 7, and a groove is provided on the bottom side of the cavity to slide and connect with the slider, which can increase the stability of the rack 7 when it moves.

[0030] Each of the two sets of racks 7 has a connecting frame 8 fixedly installed on one end. The bottom sides of the two sets of main and auxiliary grippers 3 are provided with two sets of through slots corresponding to the two sets of connecting frames 8, which can enable the racks 7 to move flexibly.

[0031] The two sets of connecting frames 8 are slidably connected to the bottom ends of the two sets of connecting frames 8, and two sliders are fixedly installed on the bottom ends of the two sets of connecting frames 8. The driving rod 9 is provided with a sliding groove, and the outer sides of the two sets of sliders are slidably connected to the inner sides of the sliding grooves. An electric telescopic rod 14 is fixedly installed on the bottom side of the main housing 1, and a connecting seat 15 is fixedly installed on the output end of the electric telescopic rod 14. The top side of the connecting seat 15 is fixedly connected to the bottom side of the driving rod 9. This allows the two sets of connecting frames 8 to move flexibly simultaneously through one set of electric telescopic rods 14, reducing the production cost of the product.

[0032] The main housing 1 is rotatably connected to one side of a rotating shaft 10. A gear 2 11 is coaxially fixedly connected to the outer side of the rotating shaft 10. Two sets of racks 2 12 are slidably connected to one side of the main housing 1, and both sets of racks 2 12 are meshed with gears 2 11. A slider 3 is fixedly installed on one side of each set of racks 2 12. Two sets of sliding grooves 3 are provided on one side of the main housing 1 corresponding to the two sets of sliders 3, and the two sets of sliders 3 are slidably connected to the two sets of sliding grooves 3.

A connecting groove is provided on one side of the connecting housing 2, which is slidably connected to both sets of movable frames 13. One end of each set of movable frames 13 is fixedly connected to one end of each set of main and auxiliary grippers 3, which can realize the flexible movement of the main and auxiliary grippers 3 and the stable gripping of materials.

[0035] The working principle of this embodiment is as follows: When the gripping mechanism is needed, firstly, the electric telescopic rod 14 and drive motor 16 in the product are connected to an external power supply and control unit. The mounting base 17 is connected to the robotic arm. The robotic arm drives the main housing 1 to move, so that the two sets of auxiliary grippers 5 are located on both sides of the material. The drive motor 16 is started to drive the rotating shaft 10 and gear 11 to rotate. Gear 11 drives rack 12 to move. Rack 12 drives the main and auxiliary grippers 3 to move through the moving frame 13. The main and auxiliary grippers 3 drive the auxiliary grippers 5 to move and grip the material. The material is then processed. When one side of the material is processed, the electric telescopic rod 14 is started to drive the drive rod 9 to move. The drive rod 9 drives the connecting frame 8 to move. The connecting frame 8 drives rack 7 to move. Rack 7 drives gear 6 and drive shaft 4 to rotate. The drive shaft 4 drives the auxiliary grippers 5 to rotate. The auxiliary grippers 5 drive the material to rotate. Then the other side of the material is processed. This process is repeated until all the surfaces of the material to be processed are completed.
