Description

Technical Field

[0001] This utility model relates to the field of spring winding technology, and more specifically, to a motorcycle front fork spring winding device. Background Technology

[0002] The motorcycle front fork spring is a core component of the front fork suspension system. It is made of spiral metal wire and mainly serves to cushion and support the vehicle. When the vehicle travels over bumpy roads or brakes and accelerates, the spring absorbs and releases energy through elastic deformation, reducing vehicle vibration and maintaining the stability of the tire's contact with the ground.

[0003] Currently, the commonly used motorcycle fork spring winding devices in the industry typically include a metal rod conveying mechanism, a clamping and limiting unit, a winding and forming module, and a cutting assembly. The specific workflow is as follows: the metal rod is clamped and continuously fed by externally configured conveying wheels, and the metal rod is stably limited by a second guide roller pressing down; subsequently, under the reverse motion of the winding roller and the winding rod, the metal rod is spirally wound and formed. When the initially formed spring enters the subsequent processing stage, the device uses limiting rollers to axially position it to ensure the stability of the spring's spiral shape. Finally, the formed spring passes through a pre-set through hole on the support plate and is cut by a matching cutter, completing the winding production of a single spring.

[0004] However, the outer wall of the winding rod of the existing winding device is usually a smooth cylindrical surface, which lacks a guide structure that matches the spiral shape of the spring. After the spring is wound and formed, during the process of conveying it to the through hole of the support plate, due to the lack of effective constraint and support on the outer diameter of the spring, the spring is prone to radial sway. The sway of the spring can easily cause deviation during cutting, which in turn makes it impossible for the cutter to be aligned with the preset cutting position, resulting in excessive deviation in the length of the finished spring and reducing the product qualification rate. Utility Model Content

[0005] This utility model proposes a motorcycle front fork spring winding device, which effectively reduces the spring's sway during the winding process, reduces the radial sway during the cutting process, avoids excessive spring length deviation, and improves the product qualification rate.

A driving component is installed on the outer wall of the mounting base. A stepper motor is fixedly connected to the top of the sliding base. A coil is fixedly connected to the output end of the stepper motor. The end of the coil passes through the mounting base and extends to its outer side. A spiral groove is opened on the outer wall of the coil. The driving component is used to drive the sliding base to move.

[0008] Preferably, the driving component is a second cylinder, which is fixedly connected to the mounting base. A connecting rod is fixedly connected to the output end of the second cylinder. The end of the connecting rod passes through the fixing plate and is slidably connected to it. The end of the connecting rod is fixedly connected to the sliding seat.

[0009] Preferably, the outer wall of the mounting base is provided with multiple limiting grooves, the inner wall of each limiting groove is slidably connected with a lifting block, the top of each mounting base is threadedly connected with an adjusting screw, the bottom of each adjusting screw extends into the corresponding limiting groove, and the end of each adjusting screw is rotatably connected to the corresponding lifting block.

[0010] Preferably, the winding device further includes a first guide roller, a second guide roller, and a winding roller. The first guide roller, the second guide roller, and the winding roller are rotatably connected to the outer wall of the corresponding lifting block. The second guide roller is located between the first guide roller and the winding roller. The first guide roller, the second guide roller, the winding rod, and the winding roller are driven by external motors. The rotation direction of the first guide roller, the winding rod, and the second guide roller is the same as the feeding direction, and the rotation direction of the winding roller is opposite to the feeding direction.

[0011] Preferably, a limiting roller is rotatably connected to the outer wall of the mounting base, and both the limiting roller and the winding rod are located between the second guide roller and the winding roller.

[0012] Preferably, a support plate is fixedly connected to the top of the mounting base, and a through hole is provided on the top of the support plate, through which the end of the coiled spring passes and rotates spirally.

The end of the connecting rod 12 passes through the fixing plate 13 and is slidably connected thereto. The end of the connecting rod 12 is fixedly connected to the sliding seat 15.

[0025] like Figure 1 and Figure 2 As shown, the outer wall of the mounting base 1 is provided with multiple limiting grooves 2, and the inner wall of each limiting groove 2 is slidably connected with a lifting block 3. The top of the mounting base 1 is threadedly connected with an adjusting screw 20, the bottom of the adjusting screw 20 extends into the corresponding limiting groove 2, and the end of the adjusting screw 20 is rotatably connected to the corresponding lifting block 3.

[0026] The winding device also includes a first guide roller 4, a second guide roller 5, and a winding roller 6. The first guide roller 4, the second guide roller 5, and the winding roller 6 are rotatably connected to the outer wall of the corresponding lifting block 3. The second guide roller 5 is located between the first guide roller 4 and the winding roller 6. The first guide roller 4, the second guide roller 5, the winding rod 18, and the winding roller 6 are driven by external motors. The rotation direction of the first guide roller 4, the winding rod 18, and the second guide roller 5 is the same as the feeding direction, and the rotation direction of the winding roller 6 is opposite to the feeding direction.

[0027] The outer wall of the mounting base 1 is rotatably connected to the limiting roller 7, and the limiting roller 7 and the winding rod 18 are both located between the second guide roller 5 and the winding roller 6.

[0028] like Figure 1 and Figure 3 As shown, a support plate 8 is fixedly connected to the top of the mounting base 1. A through hole 9 is provided on the top of the support plate 8.

[0029] Working principle: The metal rod material is clamped and conveyed by the external conveying wheel, and passes through the first guide roller 4, the second guide roller 5 and the winding roller 6 in sequence. The first guide roller 4 and the second guide roller 5 rotate in opposite directions. The first guide roller 4 and the second guide roller 5 convey the metal rod towards the winding roller 6.

The end of the metal rod is blocked by the limiting roller 7 and is wound into a spiral shape.

The rotation direction of the winding rod 18 is opposite to the rotation direction of the winding roller 6. The spiral groove 19 on the outer wall of the winding rod 18 is adapted to the spiral structure of the spring. Under the action of the rotation of the winding rod 18, the wound spring is wound along the groove 19 to extend. The groove 19 forms a conformal guide for the spring from the inside, supports the spring, and reduces the swaying of the spring during the winding process.

[0031] The wound spring is conveyed to the outside of the mounting base 1 along the extension direction of the coil 18. The end passes through the through hole 9 of the support plate 8 and rotates spirally. When the spring is conveyed to the preset length, the first cylinder 11 drives the cutter 10 to quickly cut into the through hole 9 and cut the spring.
