Description

Technical Field

[0001] The utility model relates to the field of docking mechanisms, in particular to an injection-molded nut insert installation docking mechanism. Background Art

[0002] In order to reduce the production cost of auto parts and improve the strength of auto parts themselves, more and more auto parts are being molded by insert injection. The specific operation is to place the insert inside the mold and then injection mold it, avoiding the investment of equipment and manpower in the subsequent process.

[0003] Existing insert molding technology, when placing smaller nut inserts, can easily cause the insert nut to fall due to the small contact area and high positioning accuracy required, resulting in missing parts and scrapped nuts. Furthermore, due to the small diameter of the locating pin, the cylinder pushing the nut insert into the nut can easily cause the pin to deform under stress.

[0004] Therefore, it is necessary to provide an injection molded nut insert installation docking mechanism to solve the above technical problems. Utility Model Content

[0008] A guide sleeve is fixed on the top of the cylinder, and the piston rod of the cylinder is slidably connected in the guide sleeve. The top of the guide sleeve is provided with an accommodating groove for accommodating a nut insert.

[0009] Preferably, a strong magnet is fixed to the top end of the guide sleeve.

[0010] Preferably, an external threaded sleeve connected to the manipulator is provided at the center of the bottom of the fixing plate.

[0021] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0022] Please refer to Figures 1 to 5, an injection molded nut insert installation docking mechanism, including a cylinder 2 and a fixed plate 3 for connecting to a manipulator, the fixed plate 3 is fixed with a longitudinal fixing block 4, and the end of the longitudinal fixing block 4 is fixed with a transverse connecting plate 5, forming a stable structural frame. A longitudinal slide 6 is provided in the longitudinal fixing block 4, and a movable slider 7 is cleverly slidably connected in this longitudinal slide 6. The design of the movable slider 7 is also unique. It includes a longitudinal portion 71 slidably connected in the longitudinal slide 6 and a transverse portion 72 integrally provided on the top of the longitudinal portion 71. This design allows the movable slider 7 to not only slide stably in the longitudinal slide 6, but also to achieve transverse movement and positioning through the transverse portion 72.

[0023] In order to enhance the stability of the movable slider 7 in the longitudinal slide groove 6, both ends of the longitudinal portion 71 are connected to the transverse connecting plate 5 through longitudinal springs 8, so that the movable slider 7 can maintain stable sliding and positioning even when moving at high speed or being impacted by external force.

[0024] The bottom of the cylinder 2 employs a similar design, secured with a transverse fixing block 9, to the ends of which are secured longitudinal connecting plates 10. A transverse slot 11 is provided within the transverse fixing block 9, and the transverse portion 72 of the movable slider 7 slides within this slot, enabling transverse connection and sliding movement between the cylinder 2 and the movable slider 7. To enhance the stability of the transverse portion 72 within the slot 11, both ends of the transverse portion 72 are connected to the longitudinal connecting plates 10 via transverse springs 12.

[0025] A guide sleeve 13 is fixed to the top of the cylinder 2, and the piston rod of the cylinder 2 is slidably connected to this guide sleeve 13. A receiving groove 14 is provided on the top of the guide sleeve 13 for accommodating the nut insert 1. This design not only facilitates the placement and positioning of the nut insert 1, but also ensures the stability and accuracy of the nut insert 1 during the docking process.

[0026] It's important to note that the mold features a locating pin a and a magnet b, which are stronger than the powerful magnet 15, securing the nut insert 1. Magnet b is secured behind locating pin a, which is made of stainless steel, ensuring magnetic attraction to the nut insert 1. The fixed plate 3 is connected to the robot arm via a quick-change plate. The arrangement of longitudinal and transverse springs 8, 12, and a movable slider 7 allows the cylinder 2 to move within a certain range of directions relative to the fixed plate 3, preventing deformation of the mold insert's locating pin a.

[0027] During the docking process, the nut insert 1 is first placed in the receiving groove 14, and the nut insert 1 first contacts the front guide part of the positioning pin a. When the guide part of the positioning pin a enters the nut insert 1, the robot arm stops, and the piston rod of the cylinder 2 is pushed out to push the nut insert 1 into the positioning pin a. The magnet b behind the positioning pin a attracts the nut insert 1. The robot arm retreats, and after the guide sleeve 13 is separated from the nut insert 1, the piston rod of the cylinder 2 retracts, the robot arm leaves the injection molding machine, and the mold is closed.

[0028] A strong magnet 15 is fixed to the top of the guide sleeve 13 for adsorbing and fixing the nut insert 1 .

[0029] In order to facilitate the connection and fixation with the robot arm, an external threaded sleeve 16 connected to the robot arm is provided at the bottom center of the fixing plate 3. Such a design is convenient and practical, and can quickly realize the connection and fixation of the mechanism and the robot arm.

[0030] To further enhance the stability and reliability of the mechanism, guide posts 17 are installed on the longitudinal connecting plate 10 at locations directly opposite the transverse spring 12, and on the transverse connecting plate 5 at locations directly opposite the longitudinal spring 8. These guide posts 17 effectively limit the deformation and movement of the transverse spring 12 and longitudinal spring 8, thereby ensuring that the mechanism maintains stable performance and accuracy even when in high-speed motion or subjected to external impact.

[0031] Finally, a contact sensor 18 for detecting the nut insert 1 is located on the top sidewall of the guide sleeve 13. This sensor can detect the presence of the nut insert 1 in the receiving groove 14 in real time, thereby preventing any nut insert 1 from being missed during the docking process. This design improves production efficiency while ensuring product quality and stability.

[0032] A contact sensor 18 for detecting the nut insert 1 is provided on the top side wall of the guide sleeve 13 to detect whether the nut insert 1 is present and avoid missing the nut insert 1 .

Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
