[0021] Example 1

[0022] like Figures 1-4 As shown, the quenching equipment for leaf springs proposed in this embodiment includes a mounting base 1 and a drive assembly. A drive shaft 2 and two driven shafts 3 are rotatably connected to the mounting base 1. Pulleys 5 and fixed disks 4 are coaxially arranged on both the drive shaft 2 and the driven shafts 3. Belts 6 are sleeved on the three pulleys 5. The drive shaft 2 and the two driven shafts 3 are arranged in a circular array to ensure that the wrap angle between the pulleys 5 and the belts 6 can support stable transmission. Three clamping mechanisms are arranged in a circular array on the fixed disk 4.

[0023] The clamping mechanism includes a mounting cylinder 10 mounted on a fixed plate 4, a rotating rod 11 rotatably mounted on the mounting cylinder 10, a movable block 14 threadedly connected to the rotating rod 11, two symmetrically distributed rotating frames 13 rotatably connected to the mounting cylinder 10, a connecting plate 15 rotatably connected at both ends to the movable block 14 and the rotating frame 13 respectively, and a clamping block 16 mounted on the rotating frame 13. The rotating rod 11 is provided with a threaded part 12, the movable block 14 is threadedly connected to the threaded part 12, and the rotating rod 11 is provided with a handle 17.

[0024] When the leaf spring is quenched, the leaf spring is first placed in the clamping position. Then, the rotating rod 11 is rotated by the handle 17, so that the threaded part 12 on the rotating rod 11 engages with the moving block 14. Under the restriction of the connecting plate 15, the moving block 14 will move along the axial direction of the rotating rod 11. As a result, the hinges of the connecting plate 15, the moving block 14, and the rotating frame 13 will all rotate, causing the rotating frame 13 to drive the clamping blocks 16 on both sides to move closer to each other until the leaf spring is clamped. The operation is simple and convenient.

[0025] The mounting cylinder 10 is provided with a rectangular locking block 18, which is located inside the fixed plate 4 and is used to fix the clamping mechanism on the fixed plate 4.

[0026] The drive assembly includes a motor 7 mounted on the mounting base 1, a first gear 8 driven by the motor 7, and a second gear 9 coaxially mounted on the drive shaft 2, wherein the first gear 8 and the second gear 9 are meshed together.

[0027] When the leaf spring is clamped and quenched, the motor 7 drives the first gear 8 to rotate, which in turn meshes with the second gear 9. The second gear 9 then drives the drive shaft 2 to rotate. Combined with the transmission action of the pulley 5 and the belt 6, the fixed plate 4 drives the clamping mechanism and the leaf spring to rotate at a uniform speed, so that the leaf spring can be heated and cooled evenly, thus improving the quality of the quenching process.

[0028] Example 2

[0029] like Figure 1 and Figure 4 As shown in the figure, the quenching equipment for leaf springs proposed in this embodiment, compared with the first embodiment, has a cylinder 19 above the mounting base 1, the cylinder 19 and the mounting base 1 being drivenly connected, a rotating seat 20 on the cylinder 19, a base 21 below the mounting base 1, a quenching box 22 and a cooling box 23 on the base 21, the quenching box 22 being used to heat the leaf spring, and the cooling box 23 being used to cool the leaf spring.

[0030] In this embodiment, cylinder 19 is used to drive mounting base 1 to lift and lower clamping mechanism. Rotating base 20 is connected to an external drive device (not shown) for driving rotating base 20 to achieve lifting and rotation of mounting base 1, so as to rotate unprocessed, heat-treated and cooled leaf springs. This not only allows for the simultaneous processing of multiple leaf springs, but also allows for the replacement of unprocessed and finished leaf springs, greatly saving processing time. The operation is simple and convenient, and it has good practicality.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
