Based on the implementation scheme in the utility model, all other implementation schemes obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] like Figure 1 - Figure 4As shown, a self-locking drive mechanism of a spring forming machine comprises a device shell 1, a mounting block 3 is fixedly installed on the side of the device shell 1, a rotating motor 4 is fixedly installed inside the mounting block 3, a worm 12 is fixedly installed on one end of the rotating motor 4, slide grooves 14 are provided on both sides of the inside of the device shell 1, a slider 13 is slid inside the slide groove 14, a push column 2 is fixedly installed on one end of the slider 13, a threaded rod 11 is spirally installed inside the push column 2, a positioning ring 16 is sleeved on the outside of the threaded rod 11, a turbine 10 is fixedly installed on one end of the threaded rod 11, a moving rod 5 is fixedly installed on the top of the push column 2, a mounting groove 17 is provided at one end of the moving rod 5, a sliding rod 6 is slid inside the mounting groove 17, a limiting block 7 is fixedly installed on the outside of the sliding rod 6, a friction block 8 is fixedly installed on the bottom end of the sliding rod 6, an inclined plate 9 is fixedly installed on the top of the device shell 1, and a moving groove 15 is provided on the top of the device shell 1.

[0026] The working principle of the above technical solution is as follows:

[0027] When the device is in use, the device is installed at the required position, and then the rotating motor 4 is operated to drive the worm 12 to rotate, so that the turbine 10 rotates synchronously with the meshing of the worm 12. The worm 12 is an active mechanism and the turbine 10 is a driven mechanism. When the worm 12 is stationary, the turbine 10 will not rotate, while the worm 12 can achieve forward and reverse rotation, thereby achieving drive self-locking. The rotation of the turbine 10 drives the threaded rod 11 to rotate, so that the push column 2 is driven by the rotation of the threaded rod 11 to move forward and backward, and then the moving rod 5 slides back and forth inside the moving groove 15, thereby pushing the sliding rod 6 to slide up and down inside the installation groove 17, and the friction block 8 slides on the inclined plate 9. The friction force on the inclined surface is greater than the friction force on the plane to achieve mechanical structure self-locking.

[0028] In another embodiment, Figure 1-4 As shown, the turbine 10 is meshed with the worm 12, so that when the worm 12 stops running, the worm 12 is the active mechanism and the turbine 10 is the driven mechanism. When the worm 12 is stationary, the turbine 10 will not rotate, while the worm 12 can achieve forward and reverse rotation, thereby achieving self-locking. The inclined plate 9 is an inclined surface, and the friction block 8 slides on the inclined plate 9, so that the friction force of the friction block 8 on the inclined plate 9 is greater than the friction force of the moving rod 5 in the moving groove 15, thereby achieving self-locking.

[0029] In another embodiment, Figure 1-4 As shown, the slide bar 6 slides inside the mounting groove 17, so that when the device is running, the slide bar 6 moves up and down, thereby limiting the slide bar 6, and the slider 13 slides inside the slide groove 14, so that when the push column 2 moves, the movement of the push column 2 is limited by the sliding of the slider 13, thereby preventing the push column 2 from being unstable during movement.

[0030] In another embodiment, Figure 1-4 As shown, the moving rod 5 slides inside the moving groove 15, thereby providing the friction force required for self-locking, and also limiting the moving rod 5. The positioning ring 16 is fixedly installed inside the device housing 1, and the positioning ring 16 is movably mounted on the outside of the threaded rod 11, thereby limiting the movement of the threaded rod 11, thereby achieving a stabilizing effect on the threaded rod 11.

[0031] The working principle and use process of the utility model are as follows: the turbine 10 is meshed with the worm 12, so that when the worm 12 stops running, the worm 12 is the active mechanism and the turbine 10 is the driven mechanism. When the worm 12 is stationary, the turbine 10 will not rotate, and the worm 12 can achieve forward and reverse rotation, thereby achieving self-locking. The inclined plate 9 is an inclined surface, and the friction block 8 slides on the inclined plate 9, so that the friction force of the friction block 8 on the inclined plate 9 is greater than the friction force of the moving rod 5 in the moving groove 15, thereby achieving self-locking. The sliding rod 6 slides inside the mounting groove 17, so that when the device is running, the sliding rod 6 is The sliding block 13 slides inside the sliding groove 14, so that when the push column 2 moves, the movement of the push column 2 is limited by the sliding of the sliding block 13 to prevent the push column 2 from being unstable during movement. The moving rod 5 slides inside the moving groove 15, thereby providing the friction force required for self-locking and limiting the moving rod 5. The positioning ring 16 is fixedly installed inside the device housing 1, and the positioning ring 16 is movably mounted on the outside of the threaded rod 11, thereby limiting the movement of the threaded rod 11, thereby stabilizing the threaded rod 11.

[0032] When the device is in use, the device is installed at the required position, and then the rotating motor 4 is operated to drive the worm 12 to rotate, so that the turbine 10 rotates synchronously with the meshing of the worm 12. The worm 12 is an active mechanism and the turbine 10 is a driven mechanism. When the worm 12 is stationary, the turbine 10 will not rotate, while the worm 12 can achieve forward and reverse rotation, thereby achieving drive self-locking. The rotation of the turbine 10 drives the threaded rod 11 to rotate, so that the push column 2 is driven by the rotation of the threaded rod 11 to move forward and backward, and then the moving rod 5 slides back and forth inside the moving groove 15, thereby pushing the sliding rod 6 to slide up and down inside the installation groove 17, and the friction block 8 slides on the inclined plate 9. The friction force on the inclined surface is greater than the friction force on the plane to achieve mechanical structure self-locking.
