Internal expanding core for coil assembly

Abstract

The invention discloses an internal expanding core for coil assembly. The internal expanding core comprises a base, a bearing assembly, a rotary containing barrel, an expanding loose core assembly andan internal expanding assembly, wherein the rotary containing barrel comprises a rotary barrel and a containing barrel, and the rotary barrel penetrates into one end of the base and extends out of the other end of the base; the expanding loose core assembly comprises a push-pull rod, a support disc, an expanding pin barrel and a plurality of connecting rods, and when the rotary barrel rotates, the containing barrel drives the support disc to rotate so as to drive the expanding pin barrel to rotate; the expanding pin barrel includes a tapered end; and the internal expanding assembly comprisesa pin, an adjusting bolt and two through internal expanding sheets. The tapered end of the expanding pin barrel is inserted into the tapered portion when the push-pull rod is pushed and pulled to enlarge the diameters of the internal expanding sheets or return the internal expanding sheets to the original positions. The internal expanding core for coil assembly can complete the inner expansion function, and can make manual or mechanical arm assembly to be easier and more convenient, so that the automation is facilitated.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to an internal expansion core for coil assembly. Background technique [0002] At present, when multiple coils form a circle, for example, for some high-precision motors, the circle formed by multiple coils should be very standard, so a mold is needed to ensure the accuracy of the circle. However, due to the many specifications of the motor itself, there are also many specifications of the multiple coils, so many molds are needed to complete the assembly of the coils, which obviously does not meet the expectations of enterprises to reduce costs and improve assembly efficiency. [0003] At the same time, the existing mold is set on a fixed machine platform, which is obviously unfavorable for operation, because when a plurality of the coils are assembled manually, people must turn around the machine platform, resulting in reduced production efficiency. And when a plurali...

Problems solved by technology

However, due to the many specifications of the motor itself, there are many specifications of the multiple coils, so a lot of molds are required to complete the assembly of the coils, which obviously does not meet the expectations of enterprises to reduce costs and improve assembly efficiency.

[0003] At the same time, the existing mold is set on a fixed machine table, which is obviously not conducive to operation, because when a plurality of coils are assembled manually, people must turn around the machine table, resulting in reduced production efficiency

And when a plurality of the coils are assembled by a manipulator, the manipulator must also rotate around the machine table, which makes the design of the mechanical equipment more difficult, and is also not conducive to improving production efficiency.
