The present invention relates to a tube winding device capable of winding a tube coupled to a surface of a spring used in a vehicle suspension device in a shape corresponding to the spring.

Generally, a coil spring or the like is mounted on a vehicle as a suspension device to absorb a shock caused by the driving of the vehicle, thereby protecting the vehicle body and comforting the rider.

However, automobiles have the worst of the machinery. That is, the automobile can pass through a beating road, a non-covered road, or a rough mountain road and a puddle. In such a case, a great impact is applied to the coil spring, and corrosion can be caused by foreign matter.

In addition, the coil springs are instantaneously frictionally engaged with each other when the vehicle is running, resulting in a large noise caused by the coil springs, and friction caused by foreign substances such as soil, sand, Since the surface of the coated coil spring can be damaged, a tube is attached to the outer surface of the coil spring to compensate.

However, the tube used for the coil spring has a shape of a long pipe, which has an outer diameter drawn out by extrusion, and does not have a shape corresponding to a coil spring of an automobile.

Therefore, in order to assemble the coil spring properly, it is necessary to primarily deform the shape of the tube in accordance with the coil spring. In order to cope with the amount of the coil spring produced, it is difficult to manually work the shrink tube one by one.

In other words, such a conventional coil-shaped tube formed by a passive method has a high defect ratio due to problems such as non-uniformity of coiled shape, and is a cause of cost increase due to reduction in productivity, labor cost, There is no problem.

The motor 220 may be pulley-connected to the main shaft 210 or may be directly connected to the end of the main shaft 210 to transmit rotational force to the spindle unit 200. Therefore, the main shaft 210 and the tube 10 can be rotated and wound by the driving force of the motor 220.

However, if the tube 10 is wound only upon the rotation of the spindle portion 200, the tube 10 can not be wound tightly on the main shaft 210 due to the elasticity of the tube 10 itself . In such a case, the shape corresponding to that of the coil spring for a vehicle can not be accurately obtained, resulting in a problem of reliability of the product.

Therefore, the embodiment can improve the reliability of the product and enable mass production, including the following components.

The vibration isolator 400 may be movable in the longitudinal direction of the main shaft 210 to fix the free end of the main shaft 210.
