Description

Technical Field

[0001] This utility model relates to the field of clamping tooling technology, and is an intelligent tooling with a quick-change clamp. Background Technology

[0002] Tooling, also known as process equipment, is a general term for various tools used in the manufacturing process. It encompasses multiple categories such as cutting tools, fixtures, molds, measuring tools, inspection tools, auxiliary tools, fitter's tools, and workstation equipment. In modern manufacturing, it plays a key role in ensuring smooth production processes and improving production efficiency and precision.

[0003] In the automotive manufacturing industry, with the widespread adoption of automation technology in the stamping process, multi-station production has become the mainstream manufacturing process widely used in the industry due to its high efficiency and integration. In this process mode, the lossless and stable transfer of parts between different stations is one of the core prerequisites for ensuring the high-speed and stable operation of multi-station production lines. The multi-station end effector chucks, which are responsible for gripping and transferring parts, are prone to wear and even damage due to continuous friction and mechanical action during operation, as they frequently come into contact with the parts and repeatedly clamp and open. Wear on the chucks not only directly affects the reliability of clamping the parts, leading to problems such as part positioning deviation and dropping, but may also cause production line shutdowns, disrupting normal production rhythms. Therefore, regular replacement of the chucks is a necessary operation to ensure production continuity.

[0004] However, in existing technologies, the connection between the end effector chuck and the gripper is mostly secured with screws. This traditional installation structure has significant drawbacks in practical applications: Firstly, the installation and removal of screws require specific tools, making the operation cumbersome and resulting in slow installation and removal of the chuck, which seriously affects the maintenance efficiency of the equipment. This problem is particularly prominent in scenarios where the production line needs to be quickly restored to operation. Secondly, since screws are small parts, they are easily lost due to operational negligence during the installation and removal of the chuck. This not only increases production support costs but may also delay the chuck replacement process due to missing parts, further exacerbating production line downtime losses. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical problems and provide an intelligent tooling with a quick-change chuck.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent tooling with a quickly replaceable gripper, comprising an end effector robotic arm, grippers, and grippers. At least two grippers are provided and installed on the picking end of the end effector robotic arm. The gripper is installed on the gripper, and the gripper has an installation slot into which the top of the gripper is inserted. The side wall of the gripper has a strip-shaped opening groove and a circular limiting groove, with the circular limiting groove located at the top of the strip-shaped opening groove. The side wall of the gripper has a limiting block, and the inner side of the limiting block has a rotating shaft connected to the gripper via the rotating shaft. The width of the limiting block is smaller than the width of the strip-shaped opening groove, and both ends are arc-shaped and cooperate with the circular limiting groove.

[0007] Furthermore, each of the strip-shaped opening groove, the circular limiting groove, and the limiting block is provided in twos and arranged opposite to each other.

[0008] Furthermore, the top of the chuck is provided with a through hole, through which the rotating shaft passes and is fixedly connected to two limiting blocks.

[0009] Furthermore, the through hole is provided with a receiving groove, a torsion spring is provided inside, and a protrusion is provided on the rotating shaft. The two ends of the torsion spring are respectively installed and connected to the receiving groove and the protrusion.

[0010] Furthermore, the mounting slot is provided with an automatic ejection mechanism for pushing out the clamp.

[0011] Furthermore, the automatic ejection mechanism includes a spring and a push block, with the spring fixed to the top of the mounting slot and the push block fixed to the bottom of the spring.

[0012] Furthermore, the push block makes sliding contact with the inner wall of the mounting slot.

[0013] The beneficial effects of this utility model: This utility model abandons the cumbersome traditional method of fixing with screws. It utilizes the precise cooperation between the mounting slot, strip-shaped opening groove, and circular limiting groove on the clamp and the limiting block on the clamp, combined with an automatic ejection mechanism, to greatly simplify the clamp replacement operation. During installation, simply rotate the limiting block to align it with the strip-shaped opening groove, insert the clamp into the mounting slot, and once installed, the limiting block will automatically rotate and engage with the circular limiting groove under the elastic force of the torsion spring, thus completing the limiting and fixing. The entire process requires no additional tools, the operation steps are simple and intuitive, and installation can be completed quickly.

[0014] During disassembly, simply rotate the limiting block again to align it with the slotted opening, then pull the chuck downwards. The automatic ejection mechanism further enhances disassembly speed. Compared to traditional screw fastening, this design not only eliminates the time-consuming screw tightening step and avoids problems such as improper tool use or operational errors leading to incomplete installation, but also significantly shortens the overall chuck replacement time, substantially improving equipment maintenance efficiency and effectively reducing production line downtime caused by chuck replacement. This ensures production continuity and contributes to improved overall production efficiency. Attached Figure Description

[0022] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0023] Embodiments of this utility model: such as Figure 1-5As shown in the figure, an intelligent tooling with a quick-change gripper includes an end effector robotic arm 1, grippers 2, and grippers 3. At least two grippers 2 are provided and installed on the picking end of the end effector robotic arm 1. Grippers 3 are mounted on grippers 2, and each gripper 2 has a mounting slot 4 into which the top of the gripper 3 is inserted. The side wall of the gripper 2 has a strip-shaped opening groove 5 and a circular limiting groove 6, with the circular limiting groove 6 located at the top of the strip-shaped opening groove 5. The side wall of the gripper 3 has a limiting block 7, and the inner side of the limiting block 7 has a rotating shaft 8, which connects to the gripper 3. The width of the limiting block 7 is smaller than the width of the strip-shaped opening groove 5, and both ends are arc-shaped, cooperating with the circular limiting groove 6.

[0024] It is worth noting that, such as Figure 3 , 6 As shown, the circular limiting groove 6 is a recessed groove and is located on the outer wall of the gripper 2. A portion of the strip-shaped opening groove 5 is located inside the circular limiting groove 6. The thickness of the limiting block 7 is less than or equal to the thickness of the circular limiting groove 6.

[0025] With the above structure, when installing the chuck 3, the limiting block 7 needs to be rotated to align it with the strip-shaped opening slot 5, and then the chuck 3 is inserted into the mounting slot 4. Next, the limiting block 7 is rotated back to its original position, offsetting it from the strip-shaped opening slot 5, thus achieving limiting and fixing. For disassembly, the limiting block 7 is rotated again to align it with the strip-shaped opening slot 5, and the chuck 3 can be easily pulled out. This design not only achieves quick disassembly and installation without the need for other tools, but also avoids the risk of losing screws.

[0026] Two of each of the strip-shaped opening groove 5, circular limiting groove 6, and limiting block 7 are provided and are arranged opposite to each other. The top of the chuck 3 is provided with a through hole 9, through which the rotating shaft 8 passes and is fixedly connected to the two limiting blocks 7. The through hole 9 is provided with a receiving groove 10, inside which a torsion spring 11 is provided. The rotating shaft 8 is provided with a protrusion 12, and the two ends of the torsion spring 11 are respectively installed and connected to the receiving groove 10 and the protrusion 12.

[0027] With the above structure, the configuration of the torsion spring 11 can drive the limit block 7 to automatically return to its original position. When the torsion spring 11 is in a naturally relaxed state, the limit block 7 maintains a horizontal posture.

[0028] The mounting slot 4 is equipped with an automatic ejection mechanism for pushing out the chuck 3. The automatic ejection mechanism includes a spring 13 and a push block 14. The spring 13 is fixed to the top of the mounting slot 4, and the push block 14 is fixed to the bottom of the spring 13. The push block 14 slides in contact with the inner wall of the mounting slot 4.

[0029] With the above structure, when the chuck 3 is installed, the spring 13 is compressed during the process of inserting the chuck 3 into the installation slot 4; when disassembling, after the limiting block 7 is aligned with the strip-shaped opening slot 5, the spring 13 returns to its original state, so that the chuck 3 can be easily pushed out, realizing convenient and quick disassembly.
