Technical Field

[0001] The utility model relates to the technical field of spring machines, in particular to a gap adjustment mechanism for a spring machine. Background Art

[0002] The wire feeding device is an indispensable component of the spring machine. The wire feeding device includes several rollers with arc-shaped grooves arranged on the front wall panel of the spring machine. The direction of rotation is opposite to each other. During the working process, the clamped steel wire is transported forward and enters the winding device. In the winding device, it is pushed by several different tools to bend into springs of various shapes. The number of wire feeding wheels that need to be involved is changed according to actual needs. In the actual working process, the wire feeding wheels need to be adjusted to adapt to the adjustment error and actual transportation needs.

[0003] For example, publication number "CN202762923U" discloses a "fine-tuning mechanism for a wire feed wheel of a spring machine". A porous adjustment nut is threadedly connected to the wire feed wheel shaft, and round steel can be inserted into the holes provided on the outer cylindrical wall to rotate the porous adjustment nut; the hexagonal adjustment nut is threadedly connected to the top of the wire feed wheel shaft, and the first bearing, top sleeve, second bearing, bushing, and wire feed wheel are all sandwiched between the porous adjustment nut and the hexagonal adjustment nut in sequence. Loosen the hexagonal adjustment nut and tighten the porous adjustment nut, and the first bearing, top sleeve, second bearing, bushing, and wire feed wheel all move toward the outer end of the wire feed wheel shaft; and vice versa. However, in actual applications, when there are multiple wire feed wheel pairs during the adjustment process, each wheel pair needs to be adjusted separately, and the uniformity between adjacent wheel pairs after adjustment cannot be guaranteed, and the adjustment efficiency is low. Summary of the Invention

[0004] In response to the problem that the existing technology mentioned in the background technology cannot ensure uniformity and efficiency, the utility model provides a spring machine gap adjustment mechanism that can adjust the gap synchronously, so that the adjustment process can ensure the adjustment uniformity of adjacent lower feeding spool units. At the same time, since it can be adjusted synchronously, the adjustment efficiency is improved.

The prior art adopts a method of individually adjusting the wire feed wheels. However, since the wire feed wheels in current spring machines are generally provided with multiple pairs of wheelsets, each wheel pair needs to be individually adjusted. As a result, errors generated during the adjustment process of each wheel pair make it impossible to achieve precise uniformity. Moreover, the individual adjustment of each wheel pair prolongs the adjustment time and reduces the adjustment efficiency.

Since the intermediate gear shaft unit is located in the gap adjustment assembly and the gap adjustment assembly is movably connected to the outer shell, the gap adjustment unit can move up and down relative to the outer shell, thereby driving the intermediate gear shaft unit to move radially. Since the intermediate gear shaft unit abuts against the two lower feed spool units at the same time, the radial movement of the intermediate gear shaft unit can simultaneously drive the lower feed spool unit to adjust the gap, and the two lower feed spool units can synchronously adjust the radial gap, thereby improving the efficiency and uniformity of the adjustment.

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] The existing technology adopts the method of adjusting the wire feeding wheel individually. However, since the wire feeding wheels in the current spring machine are generally provided with multiple pairs of wheel pairs, each wheel pair needs to be adjusted individually. As a result, the errors generated during the adjustment process of each wheel pair cannot be accurately unified, and each wheel pair is adjusted individually, which prolongs the adjustment time and reduces the adjustment efficiency.
