Description

Technical Field

[0001] This utility model relates to the field of buckle assembly technology, and more specifically, to a buckle assembly machine. Background Technology

[0002] In existing center-lock assembly machine technology, because the equipment needs to adapt to center-lock components of different sizes, it is usually necessary to change the receiving seat of different specifications to meet different assembly requirements. However, the design of these center-lock assembly machines does not take into account the convenience of receiving seat replacement. As a result, in actual operation, users need to manually disassemble and install the receiving seat. Each replacement requires additional time and effort. This manual adjustment method not only increases the complexity of operation, but also affects production efficiency. Especially in mass production, frequent receiving seat replacement makes the assembly process cumbersome and inefficient.

[0003] Furthermore, due to the lack of flexibility in the adjustment and installation of the existing equipment, operators usually need to rely on experience and manual adjustments to ensure the matching of the receiving seat with the center buckle component. For center buckles of different sizes, the precise alignment of the receiving seat is crucial. However, the traditional assembly machine design fails to provide a quick and accurate adjustment method, which requires multiple trial installations and fine adjustments each time the receiving seat is replaced, increasing the difficulty of operation and reducing the overall work efficiency.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a buckle assembly machine, which has the following beneficial effects:

[0017] 1. The replacement mechanism achieves stable centering and positioning through the coaxial arrangement of the fixed sleeve and the receiving sleeve. The sliding design of the guide sleeve in the guide groove ensures precise guidance during the replacement process. The arrangement of multiple flexible springs between the fixed sleeve and the receiving sleeve provides buffering and elastic support. The cooperation between the positioning rod and the positioning hole enables fast and accurate positioning and locking. The installation of the intermediate rod provides core support for the entire replacement process. This multi-positioning and guiding mechanism significantly improves the accuracy and reliability of the replacement process.

[0018] 2. The locking mechanism adopts an innovative design combining locking blocks and one-way plates. By installing locking blocks at equal intervals on the side wall of the middle rod, and cooperating with the one-way plates attached to the middle rod, a reliable one-way locking function is achieved. Multiple sliders slidably arranged in the inclined groove provide flexible adjustment capabilities through the dual action of tension springs and springs. The rounded corner design on the middle rod and the precise fit of the internal holes further enhance the stability of the locking. This multi-protection locking structure ensures the reliability and safety of the connection.

[0019] 3. The stamping mechanism achieves precise stamping action through the coordinated design of cylinder and synchronous block. The two pressing heads on the lower end face of the synchronous block are coaxial with the receiving sleeve to ensure uniform distribution of stamping force. The sliding connection of the side rod on the support frame provides stable guiding support. The entire stamping process is smooth and controllable. This precision stamping system greatly improves the efficiency and quality of the middle buckle assembly. Attached Figure Description

The replacement mechanism includes a fixed sleeve 2, a receiving sleeve 3, a positioning rod 4, a guide sleeve 5, a flexible spring 6, a middle rod 7, a snap-fit ​​mechanism, and a stamping mechanism. The fixed sleeve 2 is mounted on the support frame 1. The receiving sleeve 3 and the fixed sleeve 2 are coaxially arranged. Multiple guide grooves 8 are formed on the side wall of the fixed sleeve 2. The guide sleeve 5 is slidably connected in the guide grooves 8 and is coaxially arranged with the fixed sleeve 2. Multiple flexible springs 6 connect the fixed sleeve 2 and the receiving sleeve 3. Multiple positioning rods 4 are mounted on the guide sleeve 5. Multiple positioning holes 9 are formed on the lower end face of the receiving sleeve 3. The positioning rods 4 are slidably connected in the positioning holes 9. The middle rod 7 is mounted on the receiving sleeve 3. The snap-fit ​​mechanism is mounted in the fixed sleeve 2. The stamping mechanism is mounted on the support frame 1. The snap-fit ​​mechanism includes a snap block 10 and a one-way plate 11. The snap blocks 10 are evenly spaced in the middle. On the side wall of rod 7, one-way plate 11 is attached to the middle rod 7 and is locked onto the locking block 10. A groove 12 is provided in the fixed sleeve 2, and a slider 13 is slidably provided in the groove 12. Multiple sliders 13 are provided, and each slider 13 is provided with a tension spring 14 and a spring 15. The spring 15 is connected to the one-way plate 11, and the tension spring 14 is connected to the lower end face of the fixed sleeve 2. A rounded corner 16 is provided on the middle rod 7, and an internal hole 17 is provided on the lower end face of the fixed sleeve 2. The middle rod 7 is slidably connected in the internal hole 17. The stamping mechanism includes a cylinder 18 and a synchronizing block 19. The cylinder 18 is fixedly installed on the support frame 1. The synchronizing block 19 is installed on the extended end of the cylinder 18. Two pressing heads 20 are provided on the lower end face of the synchronizing block 19. The pressing heads 20 and the receiving sleeve 3 are coaxially arranged. A lateral rod 21 is provided on the side wall of the synchronizing block 19 and is slidably connected to the support frame 1.

[0030] In this embodiment, when changing different receiving sleeves 3, the intermediate rod 7 inside the corresponding receiving sleeve 3 is first inserted into the fixed sleeve 2. At this time, the locking block 10 is locked on the one-way plate 11. When the receiving sleeve 3 is pulled upward, the one-way plate 11 will move upward and retract accordingly, and then lock more tightly to achieve a fixed state. When it is necessary to untie, the guide sleeve 5 is pulled downward to release the connection between the positioning rod 4 and the positioning hole 9. Then, the receiving sleeve 3 is rotated to make the gap between the locking blocks 10 slide out in the one-way plate 11, thereby releasing the connection.

[0031] More specifically, after the receiving sleeve 3 is fixed, the corresponding middle buckle and spring piece are placed inside the receiving sleeve 3, and the pressing head 20 is driven by the cylinder 18 to press downward, thus completing the assembly process and ensuring ease of use.

[0032] In summary, when using or operating the overall equipment: when replacing different receiving sleeves 3, first insert the intermediate rod 7 inside the corresponding receiving sleeve 3 into the fixing sleeve 2. At this time, the locking block 10 is locked on the one-way plate 11. When the receiving sleeve 3 is pulled upward, the one-way plate 11 will move upward and retract accordingly, and then lock more tightly to achieve a fixed state. When it is necessary to release, pull down the guide sleeve 5 to release the connection between the positioning rod 4 and the positioning hole 9. Then rotate the receiving sleeve 3 to make the gap between the locking blocks 10 slide out inside the one-way plate 11, thereby releasing the connection. After the receiving sleeve 3 is fixed, place the corresponding middle buckle and spring piece inside the receiving sleeve 3, and drive the pressing head 20 downward through the cylinder 18 to press down. Thus, the assembly process can be completed, thereby ensuring the convenience of use.
