Multi-element voltage transformer CNC winding machine

Abstract

The invention discloses a numerical-control winding machine of a multi-element voltage transformer. The winding machine comprises an upper support plate and a lower support plate which are oppositely arranged on a workbench, and a winding roll (27), wherein the winding roll comprises a rolling wheel (15) and a coil sleeve (28); a gear ring (16) is arranged on the rolling wheel; guide wheels (7) are arranged on the upper support plate and the lower support plate; a driven gear (17) tangent to the gear ring is arranged on the lower support plate; the driven gear is engaged with a driving gear (18); a winding displacement device is arranged on the workbench; and a limiting plate (5) and a support frame which can realize positioning of an iron core with a multi-element coil are arranged on the workbench. According to the winding machine, the gears are numerically controlled to drive winding displacement and winding of a combined winding clamp; a ferrite multi-element iron core can be wound into the multi-element coil without separating the iron core by the side-by-side combination winding roll and the support frame; rapid winding can be achieved; the winding efficiency is improved; the winding accuracy is high; the applicability is wide; and operation is convenient.

Description

technical field [0001] The invention relates to a winding machine, in particular to a numerically controlled winding machine for a voltage transformer. Background technique [0002] The coil is an important part of the voltage transformer. Its quality and performance directly affect the use effect of the voltage transformer, and the cost of winding directly affects the manufacturing cost of the coil. At present, the voltage transformer coils have begun to be wound by machinery to solve the problems of low production efficiency and unstable quality of manual winding. However, the main problem existing in the actual production of the existing mechanical winding is that the applicability is not strong. It is only suitable for single-element coil winding, not for three-element coil winding. Therefore, it is necessary to use three The combination of single-element coils will bring troubles in assembly and combination and reduce assembly production efficiency. Second, the three-u...

Problems solved by technology

At present, the voltage transformer coils have begun to be wound mechanically to solve the problems of low production efficiency and unstable quality of manual winding.

However, the main problem existing in the actual production of the existing mechanical winding is that the applicability is not strong. It is only suitable for single-element coil winding, not for three-element coil winding. Therefore, it is necessary to use three The combination of single-element coils will bring troubles in assembly and combination and reduce assembly production efficiency. Second, the three-unit coil iron core silicon steel sheet consumes a lot of materials, consumables, and high manufacturing costs.

The second problem is that it is inconvenient to locate different types of components on the same winding machine, increasing the non-production time, and there is also inaccurate positioning, which is not conducive to the quality assurance of winding
