Embodiment Construction

[0013] Referring to the above figures, the following examples are provided. Examples will help to understand the present invention, but do not limit the content of the present invention. All deformations that can be directly derived or associated by those skilled in the art from the content disclosed in the present invention should be considered as the protection scope of the present invention.

[0014] In this method for fixing the driving coil of the needle selector, the driving coil 2 that controls the movement of the blade 1 of the needle selector is installed on the coil seat 3 and is fixedly connected with it. The steps of this method include: manufacturing the coil base 3 with grooves on the surface in advance, putting the driving coil 2 into the groove of the coil base 3, and then filling the groove with glue.

[0015] The jelly is made of insulating resin varnish. The manufacturing method of the coil base 3 is direct casting. The cross section of the groove is a se...

Abstract

The invention discloses method for fixing drive coil of needle-gating device. Drive coil of controlling movement of blade in the needle-gating device is installed in the coil holder, and is connected to the coil holder fixedly. The method includes steps: fabricating the coil holder with flute on surface in advance; placing drive coil to the flute in the coil holder; filling jelly into the flute. Advantages of the method are: simple and easy of implementation, obvious cooling effect, and increasing service life of drive coil.

Description

technical field [0001] The invention relates to an installation method, in particular to an installation method of a needle selector component. Background technique [0002] The needle selector controls the movement through the driving coil. Since the driving coil is driven by current, it is easy to generate heat and heat. If the heat conduction is not good, the service life will be reduced, and even the coil will be damaged directly. [0003] At present, there are two ways to fix the driving coil: one is to choose a card seat with a bayonet at both ends that is hollow in the middle, and snap the two ends of the coil into the bayonet of the card seat; the other is to use a coil seat with a through hole drilled in advance. Cover, embed the driving coil in the coil seat cover as a whole, and fix it by welding or bonding. The former method cools the driving coil through air convection, and the effect is not obvious; the latter method cools down throu...
