Embodiment 1

[0016] The height of the winding head h1=2cm, the radius r1=1cm, there are 6 longitudinal positioning grooves, and the required length of the starting wire is about 8cm;

[0017] It can be calculated from r1=1cm that the circumference of the winding head L1=2πr1=6.28cm, then in order to meet the requirement that the length of the starting thread is at least 8cm, the length of L1+h1=8.28cm can be wound, that is, from the winding head and the winding shaft From the joint, pass through half of the longitudinal positioning groove, the entire horizontal positioning groove and half of the longitudinal positioning groove in sequence, and finally wind out the winding head.

Embodiment 2

[0019] The height of the winding head is h2=4cm, the radius r2=2cm, there are 6 longitudinal positioning grooves, and the required length of the starting wire is about 6cm;

[0020] It can be calculated by r2=2cm that the circumference of the winding head L2=2πr2=12.56cm, then in order to meet the requirement that the length of the starting thread is about 6cm, the length of 1 / 6×L2+h2=6.1cm can be wound, that is, from The connection between the winding head and the winding shaft passes through half of the longitudinal positioning groove, 1 / 6 of the horizontal positioning groove and half of the longitudinal positioning groove in sequence, and finally winds out the winding head. Since there are 6 longitudinal positioning grooves, the distance of 1 / 6 of the transverse positioning grooves can be intuitively determined by the position of the longitudinal positioning grooves.

[0021] It can be seen that using this method, when determining the length of the starting thread, it is ne...

Abstract

The invention discloses a device used for measuring and positioning a transformer winding shaft lead wire The device comprises a winding head, a winding shaft and a positioning hook. The winding head is cylindrical, and the winding head is provided with a transverse positioning groove and vertical positioning grooves; the transverse positioning groove is arranged in the sidewall of the winding head, and the transverse positioning groove and the winding head are coaxial and have the same center of circle; and the vertical positioning grooves are distributed in the edge of the winding head uniformly at an equal interval, and are perpendicular to the axis of the winding head. The device used for measuring and positioning the transformer winding shaft lead wire can be operated simply, during the winding process, operators do not need to stop the work at hand, winding, measuring and positioning are completed commonly in one process, interruption of work and replacement of the measuring tool are not needed, operators can form an inertia to complete repetitive work, the working efficiency is greatly improved, and because extra measuring work is omitted, the labor cost is reduced.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a device for measuring and positioning transformer winding shaft lead wires. Background technique [0002] When winding coil inductors, it is usually necessary to limit the lead length of the inductor coil in some products, so it is necessary to increase the production process of measuring the lead length in the process of winding the inductor to ensure the accuracy of the lead length. However, adding a special measurement step will reduce production efficiency and increase labor costs, and the measurement speed with a ruler is slow and the accuracy is low. Contents of the invention [0003] In order to solve the above problems, the invention discloses a device for measuring and positioning transformer winding shaft lead wires. [0004] Technical scheme of the present invention is as follows: [0005] A device for measuring and positioning transformer winding shaft lead wires, inc...
