When it is necessary to repair or replace the rotary soldering module, the traditional connection method is cumbersome to disassemble, which consumes a lot of manpower and time costs, and seriously restricts the maintenance efficiency and production progress of the equipment. To address this, we have proposed a five-wire terminal twisting and soldering machine. Utility Model Content

Multiple sets of locking structures are installed inside the sleeve 7, and the multiple sets of locking structures are evenly distributed along the circumference of the sleeve 7 to lock and fix the sleeve 7 to the fixing rod 14. The protective tube 4 is installed on the outer cylindrical surface of the sleeve 7; The locking structure, located between the protective tube 4 and the sleeve 7, is used to open and close the locking structure.

[0018] Furthermore, the outer cylindrical surface of the sleeve 7 is provided with multiple circumferentially distributed stepped holes 8. The stepped holes 8 are located at the end of the sleeve 7 away from the rotating soldering module 3. The smaller end of the stepped hole 8 extends into the interior of the sleeve 7. The stepped holes 8 are used to install the locking structure.

[0019] Furthermore, the locking structure includes a pressure block 11, a connecting rod 13, and a spherical protrusion 15. The connecting rod 13 is fixedly connected to one side of the pressure block 11, and the spherical protrusion 15 is fixedly connected to the other end of the connecting rod 13. The edge of the pressure block 11 facing away from the connecting rod 13 has a rounded corner. The pressure block 11 is inserted into the larger end of the stepped hole 8. The end of the connecting rod 13 connected to the pressure block 11 is inserted into the larger end of the stepped hole 8, and the other end of the connecting rod 13 is inserted into the smaller end of the stepped hole 8. The spherical protrusion 15 penetrates the stepped hole 8 inside the sleeve 7. The spherical surface of the spherical protrusion 15 fits tightly against the fixing rod 14. The pressure block 11 is used to install the connecting rod 13, and the connecting rod 13 is used to connect the pressure block 11 and the spherical protrusion 15. The pressure block 11 and the connecting rod 13 extend and retract within the stepped hole 8. The spherical protrusion 15 fits tightly against the fixing rod 14 to lock the connection between the fixing rod 14 and the sleeve 7.

[0020] Furthermore, the locking structure also includes a second spring 12. The second spring 12 is fixedly connected to one side of the pressure block 11 connected to the connecting rod 13. The connecting rod 13 is inside the second spring 12. The other end of the second spring 12 is fixedly connected to the stepped surface of the stepped hole 8.

It is fixed to the outer cylindrical surface of sleeve 7 and is used to install the clamping block fixing structure. At the same time, it also protects the internal structure.

The diameter of the hole is larger at one end and smaller at the other. The larger diameter end is used to install components such as pressure block 11, and the smaller diameter end connects to the inside of sleeve 7 to achieve the locking function. Spring 9: A helical spring structure, one end of which is connected to the pressure ring 10, and the other end is fixed inside the protective tube 4. It pushes the pressure ring 10 through the elastic force to press the pressure block 11. Pressure ring 10: a circular ring structure, sleeved on the outside of sleeve 7, corresponding to pressure block 11, pressing pressure block 11 under the action of spring 9, or releasing pressure block 11 under the pull of slide rod 5; Pressure block 11: Block structure with rounded corners on one side, inserted into the large diameter end of the stepped hole 8, used to install the connecting rod 13, which moves under the action of the pressure ring 10 to control the extension and retraction of the spherical protrusion 15; Spring 2 12: a helical spring structure located inside the stepped hole 8, one end of which is connected to the pressure block 11, and the other end is fixed to the stepped surface of the stepped hole 8.

[0026] Working Principle: When the modular five-wire crimping and twisting tinning machine is working, the unique connection structure achieves stable coordination between the rotating module 2 and the rotating tinning module 3. The connection between the fixed rod 14 and the sleeve 7 is the basic connection. The multiple sets of locking structures distributed around the inner circumference of the sleeve 7 are the core components that ensure a stable connection. During installation, the elastic force of spring 19 pushes the pressure ring 10, causing the pressure ring 10 to press the pressure block 11 into the stepped hole 8. The pressure block 11 drives the connecting rod 13 and the spherical protrusion 15 to move. The spherical surface of the spherical protrusion 15 fits tightly against the fixed rod 14, and spring 2 12 is in a compressed state. At this time, the multiple sets of spherical protrusions 15 form a ring-like locking on the fixed rod 14 from multiple directions, firmly fixing the sleeve 7 and the fixed rod 14. This allows the rotating tinning module 3 to be stably installed on the rotating output shaft of the rotating module 2, effectively resisting the vibration and impact generated by the long-term high-speed operation of the equipment, ensuring accurate tinning position. When the tinning machine is working, the rotation output shaft of the rotating module 2 drives the fixed rod 14 to rotate. The fixed rod 14 transmits the rotational power to the sleeve 7 and the connected rotating tinning module 3 through the locking structure. Under the power drive, the rotating tinning module 3 performs the twisting and tinning operations of the wire end, realizing an efficient and stable production process. When the equipment is being maintained or the rotating tinning module 3 is being replaced, the operator pulls the slide rod 5 to drive the pressure ring 10 to overcome the elastic force of the spring 9 and move away from the pressure block 11. The pressure ring 10 no longer presses against the pressure block 11, and the spring 12, which is in a compressed state, releases its elastic force, pushing the pressure block 11 and the connecting rod 13, causing the spherical protrusion 15 to retract into the stepped hole 8, releasing the locking constraint on the fixed rod 14. At this time, the sleeve 7 can be easily separated from the fixed rod 14, and the rotating tinning module 3 can be quickly disassembled, greatly simplifying the maintenance and replacement process and reducing maintenance time and labor costs.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
