DETAILED DESCRIPTION

The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

As shown in Fig. 1-4, the utility model provides a technical solution: an arc spring shaping fixture, including a clamp body 1, a sleeve plate 4 is connected to the clamp body 1, a fixed plate 2 is connected inside the clamp body 1, a limit plate 3 is arranged inside the fixed plate 2, a threaded rod 5 is rotatably connected inside the clamp body 1, a movable plate 6 is externally threadedly connected to the threaded rod 5, and a motor 10 is arranged outside the clamp body 1;

The threaded rod 5 is rotatably connected in the sleeve plate 4, and the motor 10 is connected to the threaded rod 5. By setting the sleeve plate 4, when the threaded rod 5 is driven by the motor 10 to rotate, the threaded rod 5 will rotate in the sleeve plate 4, so that the sleeve plate 4 plays a certain positioning role in the rotation of the threaded rod 5, avoiding the threaded rod 5 from getting stuck when rotating;

The side of the movable plate 6 is connected with a take-up plate 7, the movable plate 6 is externally threaded with a threaded rod 8, the threaded rod 8 is rotatably connected with a mounting plate 9, the limit plate 3 is connected with a clamping block 11, the clamping block 11 is slidably connected with a push rod 17, a slide groove 13 is provided in the fixed plate 2, the limit plate 3 is externally connected with a slider 12, the slider 12 is slidably connected in the slide groove 13, by setting the slider 12 and the slide groove 13, when a pulling force or a pushing force is applied to the limit plate 3, the slider 12 on the side of the limit plate 3 will slide in the slide groove 13, so that the slider 12 and the slide groove 13 play a certain guiding role in the movement of the limit plate 3;

A groove 20 is provided in the clamping block 11, and a mounting rod 14 is slidably connected in the groove 20. An auxiliary block 15 is connected to one end of the mounting rod 14. A spring 21 is connected to the outer sleeve of the mounting rod 14. By providing the spring 21, when the mounting rod 14 is affected by the tension, it will slide in the groove 20, and the mounting rod 14 will drive the spring 21 to deform when sliding, so that the spring 21 plays a certain supporting role for the movement of the mounting rod 14. When the mounting rod 14 loses resistance, it will be reset by the spring 21.

An auxiliary rod 16 is connected to one side of the auxiliary block 15, a limit rod 18 is provided in the push rod 17, the mounting rod 14 is connected in the groove 20 through a spring 21, the auxiliary rod 16 is slidably connected in the clamping block 11, an oblique groove 19 is provided in the auxiliary block 15, and the limit rod 18 is slidably connected in the oblique groove 19;

By setting the auxiliary rod 16, when the push rod 17 moves, the limit rod 18 will slide in the inclined groove 19, and when the auxiliary block 15 is subjected to a thrust, the auxiliary rod 16 will slide in the clamping block 11, so that the auxiliary rod 16 plays a certain auxiliary role in the movement of the auxiliary block 15, thereby preventing the auxiliary block 15 from tilting during movement.

The working principle of the utility model is:

When the clamp is clamping the arc spring, the motor 10 can drive the threaded rod 1 5 to rotate, and the moving plate 6 will move on the surface of the threaded rod 1 5. When the threaded rod 1 5 moves to an appropriate position, one end of the arc spring is placed on the top of the strap 7, and then the threaded rod 2 8 drives the mounting plate 9 to move. After moving, the mounting plate 9 will overlap with one end of the arc spring.

When both ends of the arc spring are installed, the push rod 17 is pressed, and the limit rod 18 slides in the inclined groove 19 when the push rod 17 moves. The auxiliary block 15 applies a pulling force to the installation rod 14 when it moves, and the installation rod 14 causes the spring 21 to deform when it slides in the groove 20. Then, when a pulling force is applied to the limit plate 3, it slides in the fixed plate 2. When the limit plate 3 moves to the appropriate position and contacts the apex of the arc spring, the push rod 17 is released, and the installation rod 14 contacts the side of the fixed plate 2 after being reset by the spring 21.
