Technical Field

[0001] This utility model relates to the field of robotic gripper technology, specifically a robotic gripper that is easy to assemble and disassemble. Background Technology

[0002] In today's industrial automation production processes, robotic grippers are indispensable components and are widely used in various production scenarios. However, existing robotic grippers have revealed a series of problems that urgently need to be solved in practical use.

[0003] Traditional robotic grippers are often extremely cumbersome to install and disassemble. Most grippers rely on numerous complex bolt connections, which are scattered and require a lot of time to tighten one by one during installation and a lot of effort to unscrew them one by one during disassembly. Moreover, some bolts are hidden and require special tools to operate, which undoubtedly increases the difficulty and time cost of installation and disassembly. In actual production, when it is necessary to change grippers to adapt to different production tasks or to perform routine maintenance and repairs on the grippers, the cumbersome disassembly and assembly process often leads to long production line downtime, which seriously affects production efficiency.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a robotic gripper that is easy to assemble and disassemble, including a connecting seat 1, a mounting connecting plate 2 at the lower end of the connecting seat 1, mounting grooves 3 inside the connecting seat 1 and the mounting connecting plate 2, the connecting seat 1 and the mounting connecting plate 2 being mounted on the robotic arm by mounting bolts 4, a first connecting block 5 at the upper end of the connecting seat 1, a drive motor 6 inside the first connecting block 5, a rotating shaft 7 at the transmission end of the left end of the drive motor 6, a first thread 8 on the right side of the rotating shaft 7, the rotating shaft 7 passing through a first slider 9, and a thread inside the first slider 9 that is compatible with the first thread 8.

[0025] The upper end of the first slider 9 is provided with a first fastening plate 10, and the left side of the first fastening plate 10 is provided with a first rubber protective pad 11. The left side of the rotating shaft 7 is provided with a second thread 12, and the rotating shaft 7 passes through the second slider 13. The interior of the second slider 13 is provided with a thread that matches the second thread 12. The left side of the rotating shaft 7 is provided with a movable ring 14. The drive motor 6 serves as the power source, providing rotational power. Through the threaded engagement between the rotating shaft 7 and the first slider 9 and the second slider 13, the opening and closing actions of the first fastening plate 10 and the second fastening plate 15 are realized, completing the clamping and releasing operation of the workpiece. The mounting groove 3 and the mounting bolt 4 enable convenient installation and disassembly between the fixture and the robot. The guide rod 21 and the auxiliary ring 18 ensure the stability and accuracy of the first fastening plate 10 and the second fastening plate 15 during the movement process.

[0026] The upper end of the second slider 13 is provided with a second fastening plate 15, and the right side of the second fastening plate 15 is provided with a second rubber protective pad 16. The upper end of the connecting seat 1 is provided with a second connecting block 17, and the left and right ends of the inner side of the second connecting block 17 are provided with auxiliary rings 18. The middle part of the auxiliary ring 18 is provided with a guide rod 21, which passes through the third slider 19 and the fourth slider 20. The upper end of the third slider 19 is fixedly connected to the lower end of the first fastening plate 10, and the upper end of the fourth slider 20 is fixedly connected to the lower end of the second fastening plate 15. During the movement of the first fastening plate 10 and the second fastening plate 15, the guide rod 21 and the auxiliary ring 18 can play a good guiding and supporting role, ensuring the smoothness and accuracy of the movement of the first fastening plate 10 and the second fastening plate 15, so that the fixture can more reliably complete the clamping workpiece.

[0027] Working Principle: When this easily assembled and disassembled robotic gripper is needed, the drive motor 6 serves as the power source for the entire gripper. When it starts operating, it provides stable rotational power. The transmission end of the drive motor 6 is connected to the rotating shaft 7, so the rotation of the motor drives the rotating shaft 7 to rotate as well. The rotating shaft 7 has threads with different directions of rotation: the right side has the first thread 8, and the left side has the second thread 12. The first slider 9 has a thread that matches the first thread 8, and the second slider 13 has a thread that matches the second thread 12. When the rotating shaft 7 rotates, based on the thread transmission principle, the first slider 9 moves linearly along the direction of the first thread 8, and the second slider 13 moves linearly along the direction of the second thread 12. Because the threads have opposite directions of rotation, the first slider 9 and the second slider 13 move towards or away from each other, thus achieving the clamping or releasing operation of workpieces of different sizes. A first fastening plate 10 is fixedly connected to the upper end of the first slider 9, and a second fastening plate 15 is fixedly connected to the upper end of the second slider 13. The movement of the first slider 9 and the second slider 13 also drives the movement of the first fastening plate 10 and the second fastening plate 15. A first rubber protective pad 11 is provided on the left side of the first fastening plate 10, and a second rubber protective pad 16 is provided on the right side of the second fastening plate 15. When the first fastening plate 10 and the second fastening plate 15 move towards each other to clamp the workpiece, these two rubber protective pads can effectively buffer the movement and prevent damage to the workpiece surface. A second connecting block 17 is provided at the upper end of the connecting seat 1. Auxiliary rings 18 are provided at both ends of the inner side of the second connecting block 17. A guide rod 21 passes through the middle of the auxiliary ring 18. The third slider 19 and the fourth slider 20 are sleeved on the guide rod 21. The upper end of the third slider 19 is connected to the first fastening plate 15. The lower end of the fixed plate 10 is fixedly connected, and the upper end of the fourth slider 20 is fixedly connected to the lower end of the second fastening plate 15. During the movement of the first fastening plate 10 and the second fastening plate 15, the guide rod 21 and the auxiliary ring 18 can play a good guiding and supporting role, ensuring the smoothness and accuracy of the movement of the first fastening plate 10 and the second fastening plate 15, so that the fixture can more reliably complete the clamping workpiece. During installation, the mounting connecting plate 2 at the lower end of the connecting seat 1 is aligned with the corresponding position on the robot arm through the mounting groove 3, and then the mounting bolt 4 is used to tighten it, so that the installation of the fixture and the robot arm can be completed quickly. During disassembly, the mounting bolt 4 is unscrewed, and the fixture can be easily removed from the robot arm, realizing convenient disassembly and assembly operations.

[0028] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
