[0021] In order to more clearly understand the above-mentioned objects, features and advantages of this utility model, the following further describes this utility model in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand this utility model. However, this utility model can also be implemented in other ways different from those described herein. Therefore, this utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1: Refer to Figure 1 - Figure 5 As shown in the figure: A batch medical rubber cap clamping fixture mechanism includes a base plate 9. One side of the base plate 9 is fixedly connected with a side plate I 5. One side of the inner wall of the side plate I 5 is fixedly connected with a reinforcement bar 8. A clamping mechanism is arranged on one side of the reinforcement bar 8. The clamping mechanism includes a connector I 4, a clamping plate I 7 and a clamping plate II 17. One side of the clamping plate I 7 is fixedly connected with a limit block I 15. One side of the clamping plate I 7 is fixedly connected with the connector I 4. One side of the connector I 4 is fixedly connected with a hydraulic cylinder I 10. One side of the hydraulic cylinder I 10 is fixedly connected with a support plate 20. One side of the support plate 20 is fixedly connected with a hydraulic cylinder II 11. One end of the hydraulic cylinder II 11 is fixedly connected with a connector II 14. One side of the connector II 14 is fixedly connected with the clamping plate II 17. One side of the clamping plate II 17 is fixedly connected with a limit block II 16. And one side of the clamping plate II 17 is fixedly connected with a slide block 23. One side of the slide block 23 is slidably connected with a slide rail 22. One side of the slide rail 22 is fixedly connected with the support plate 20. One side of the support plate 20 is fixedly connected with a guide rod 21. The outer ring surface of the guide rod 21 is sleeved with a cap body 2.

[0024] The use of multiple limiting blocks 15 can increase the contact area between the top of the first clamping plate 7 and the cap body 2. The use of the second limiting block 16 can increase the contact area between the top of the second clamping plate 17 and the cap body 2. A through groove is provided on one side of the first clamping plate 7, and the second limiting block 16 penetrates through the through groove on the first clamping plate 7, which can reduce the movement interference of the first clamping plate 7 on the second limiting block 16 when the second limiting block 16 moves with the second clamping plate 17. The bottom of the second clamping plate 17 is connected to the slider 23, and the slide rail 22 can be used to guide the movement of the second clamping plate 17, thereby improving the stability of the second clamping plate 17 during movement. When the cap body 2 is placed above the entire fixture, the guide rod 21 can guide the placement of the cap body 2 and reduce the misalignment during the placement of the cap body 2. The multiple cap bodies 2 are quickly clamped by the first limiting block 15 and the second limiting block 16, thereby reducing the shaking of the cap body 2 during processing and improving the stability of the cap body 2 on the fixture.

[0025] Embodiment 2: As Figure 2 - Figure 5 shown, the first clamping plate 7 and the second clamping plate 17 are slidably connected. An auxiliary rod 3 is provided on one side of the first clamping plate 7. An installation part is inserted through the outside of the auxiliary rod 3. One side of the installation part is fixedly connected to the first side plate 5. The first side plate 5 is penetrated by the first hydraulic cylinder 10 and the second hydraulic cylinder 11. One side of the first side plate 5 is fixedly connected to a limiting plate 1. One side of the limiting plate 1 is fixedly connected to an auxiliary plate 6. One side of the auxiliary plate 6 is fixedly connected to a reinforcing strip 8. One side of the first side plate 5 is fixedly connected to a second side plate 12. One side of the second side plate 12 is fixedly connected to a support plate 20. One side of the second side plate 12 is bolted to a connecting flange 13. Mounting seats 19 are symmetrically arranged on both sides of the connecting flange 13. One side of the mounting seat 19 is fixedly connected to the second side plate 12. An auxiliary part 18 is installed on one side of the mounting seat 19.

[0026] The installation part can support the auxiliary rod 3. The movement range of the first clamping plate 7 can be limited by the auxiliary rod 3. The first hydraulic cylinder 10 and the second hydraulic cylinder 11 penetrate through the first side plate 5, which can reduce the movement interference of the first side plate 5 on the first connecting part 4 and the second connecting part 14 during movement. The reinforcing strip 8 can support the two first side plates 5 on both sides to achieve the stable connection of the two first side plates 5. At the same time, the reinforcing strip 8 can improve the strength of the auxiliary plate 6 during use and reduce the deformation caused by the collision between the limiting plate 1 and the auxiliary plate 6 during use. The mounting seat 19 can assist in the installation of the auxiliary part 18 on one side of the second side plate 12. The connecting flange 13 can be installed on one side of the second side plate 12 through bolts, thereby facilitating the connection of the second side plate 12 to the robotic arm by using the connecting flange 13 and facilitating the movement of the entire fixture by using the robotic arm.

[0027] Usage method and working principle of the device: First, connect the connecting flange 13 to the end of the robotic arm, sleeve the medical cap body 2 onto the guide rod 21, and then use the first hydraulic cylinder 10 to drive the first connecting member 4 to move towards the side close to the first side plate 5. At this time, the first clamping plate 7 drives a plurality of first limit blocks 15 to overlap with one side of the cap body 2. The second hydraulic cylinder 11 drives the second connecting member 14 to move towards the side close to the first side plate 5, and the second connecting member 14 drives the second clamping plate 17 and a plurality of second limit blocks 16 to overlap with the other side of the cap body 2. The clamping and limiting of the cap body 2 are achieved through the first limit blocks 15 and the second limit blocks 16. After the clamping is completed, use the robotic arm to move the entire fixture into the machining area of the machine tool. The limit plate 1 and the auxiliary plate 6 limit one side of the installation position. When the machining of the cap body 2 is completed, the robotic arm removes the fixture from the machine tool, flips the fixture, and then the cap body 2 can be moved above the conveyor belt. The first clamping plate 7 and the second clamping plate 17 move in the opposite direction, and the first limit blocks 15 and the second limit blocks 16 no longer clamp the cap body 2. At this time, the cap body 2 falls onto the conveyor belt to achieve blanking, and the cap body 2 can be continuously processed, so that the processed cap body 2 can be applied to medical products.

[0028] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
