DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0021] Reference Figure 1-3A spring production fixture includes a base 2, with countersunk grooves 21 at the four corners of the base 2, a threaded hole at the center of the countersunk groove 21, and a weight-reducing groove at the center of the base 2 to reduce the weight of the entire base 2. A support frame 6 is provided in a circular array on the top of the base 2, and a mounting plate 22 is fixedly provided on the top of the support frame 6. The support frame 6 leaves space for installing parts at the bottom of the mounting plate 22, and is fixed to the ground through threaded holes and bolts.
[0022] I-shaped grooves 1 are provided at the four corners of the top of the mounting disk 22, an I-shaped block 8 is slidably arranged in the I-shaped groove 1, an expansion plate 7 is fixedly arranged on the top of the I-shaped block 8, and the outer side surface of the expansion plate 7 is arranged as an arc surface 71, a center column 11 is rotatably connected to the bottom center of the mounting disk 22, a common disk 10 is fixedly arranged on the outer wall of the center column 11, and a fixing component for clamping and fixing springs with different inner diameters is arranged on the common disk 10.
[0023] The fixed component includes a long drive rod 9, a short drive rod 91, and a drive cylinder 4. The short drive rod 91 is rotatably connected to the bottom of the common disk 10. The long drive rod 9 is vertically fixed at the end of the short drive rod 91. The other end of the long drive rod 9 is rotatably connected to the bottom of the I-shaped block 8. A drive block 3 is fixedly set at the bottom of one group of I-shaped blocks 8. The drive block 3 is fixed to the output end of the drive cylinder 4. The shell of the drive cylinder 4 is fixedly connected to the side of the connecting block 5. The connecting block 5 is fixedly connected to the side of the I-shaped block 8. The height of the drive block 3 and the connecting block 5 is appropriately set. When the drive cylinder 4 is fixed horizontally, the drive cylinder 4 is directly below the four groups of long drive rods 9 and the short drive rod 91.
[0024] It should be added that electromagnetic valves are provided at the air inlet and outlet ends of the driving cylinder 4, so that the extension length of the driving cylinder 4 can be controlled, thereby driving the four groups of expansion plates 7 to move closer to or away from each other at an appropriate distance, and the outer side surface of the expansion plate 7 is set to a curved surface 71 for fitting the inner diameter of the spring.

[0026] In the initial state, the driving cylinder 4 is in a fully retracted state, and the four groups of expansion plates 7 are at the shortest distance between each other. The worker sets the spring to be clamped on the four groups of expansion plates 7 and starts the driving cylinder 4. The driving cylinder 4 extends, driving two groups of opposite I-blocks 8 to move away from each other. The two groups of I-blocks 8 drive the common disk 10 to rotate through the short drive rod 91 and the long drive rod 9, and the common disk 10 drives the remaining expansion plates 7 to move away from each other through the remaining long drive rods 9 and the short drive rods 91, thereby fixing and clamping the spring.
