Abstract

The utility model relates to a crochet for a winding machine, which comprises a crochet body, wherein the lower end of the crochet body is provided with a connecting part, the upper end of the crochet body is provided with a crochet head, a crochet opening is arranged between the crochet head and the crochet body, the top of the crochet head is a guide part inclining towards one direction, and the guide part spans across the central axis of the crochet body. Through setting up the guide part in one side of gib head, make the highest point skew crochet needle's central line, when copper line has a small amount of position deviation, debugging position have the deviation, the copper line still can make all copper lines in the whole crochet needle diameter range by the effect of guide part to the same side of crochet needle, guarantee the crochet needle stability, accurate crochet line for production process has better fault-tolerant, has improved stability and the continuity of production greatly, improves the work efficiency of coiling machine.

Description

Crochet hook for winding machine Technical Field The utility model relates to the technical field of automatic winding processing of induction coils, in particular to a crochet hook for a winding machine. Background Bearded needles are important parts required to be used in the production process of the induction coil. In one of the wire hooking modes of the automatic winding machine, the center of the crochet hook is not located at the axis of the magnetic ring, but is deviated from the central axis of the magnetic ring, when the crochet hook ascends from the lower side of the magnetic ring to the upper side of the magnetic ring and then goes to one side of the copper wire, the crochet hook moves upwards, after the crochet hook passes over the copper wire, the crochet hook rotates to one side by 90 degrees, the copper wire enters the crochet hook, then the crochet hook moves downwards, and the copper wire is hooked to the lower side of the magnetic ring from the upper side of the magnetic ring through the inner hole, so that the copper wire is wound on the magnetic ring, as shown in fig. 5. In the process, two problems are that firstly, the adjustable range of the crochet hook is small due to the small inner space of the magnetic ring, the copper wire is not necessarily positioned at an ideal crochet hook position and can be possibly left or right, and secondly, the position of the crochet hook is adjusted by mechanical assembly or deformation of the crochet hook or collision is generated due to the small inner space of the magnetic ring, so that the position of the crochet hook head deviates from a target position. Both of these problems can cause the copper wire to slip to the back of the crochet, making the crochet less than the wire. As shown in fig. 6, for example, after the crochet is required to be lifted, the copper wire is required to be positioned on the left side of the crochet, and before the crochet is lifted, the position of the copper wire relative to the crochet must be positioned on the left side of the crochet center line (such as the a and b positions). If the copper wire is in the neutral position c, there is uncertainty that the crochet hook may or may not be able to hook the wire normally. If the copper wire is slightly deviated to the right (as in the position d), the copper wire can slide to the right of the crochet hook, and the crochet hook is installed on the driving structure and can only rotate 90 degrees to one side, so that the crochet hook cannot hook the copper wire positioned on the right side of the crochet hook, the production is interrupted, and the normal production of the inductance coil is affected. Disclosure of utility model The utility model provides a crochet hook for a winding machine, aiming at the prior art. The technical scheme includes that the crochet hook for the winding machine comprises a crochet hook body, wherein a connecting part is arranged at the lower end of the crochet hook body, a crochet hook is arranged at the upper end of the crochet hook body, a crochet hook opening is arranged between the crochet hook and the crochet hook body, a guide part which is obliquely arranged is arranged at the top of the crochet hook, and the guide part spans the central axis of the crochet hook body. Based on the technical scheme, the utility model can also be improved as follows: preferably, the guiding part is arranged on one side where the hook opening is located, and the guiding part is inclined downwards towards the direction of the hook opening. The copper wire crossing the diameter of the whole crochet hook can be guided to the crochet hook side, by adopting the structure, the copper wire directly falls into the crochet hook after crossing the guide part, the crochet hook can be realized without rotating the crochet hook, and the crochet hook efficiency is improved. Preferably, the guide portion is provided on a side surface of the hook opening. The structure can lead the copper wire which spans the whole diameter of the crochet hook to a certain side surface of the crochet hook, so that the crochet hook can be rotated by a fixed angle towards a certain fixed angle. Further, the inner surface of the hook opening is a smooth arc line. Because the hook opening subsequently involves the hook wire and can generate sliding friction with the copper wire, the inner surface is set to be a smooth arc line, and the abrasion to the surface of the copper wire in the process of hooking the wire can be reduced. Preferably, the inclination angle beta of the guide part is 30-70 degrees. Preferably, the crochet body is provided with an avoidance part, and the avoidance part and the hook opening are positioned on the same side and extend upwards to the hook opening. Preferably, the connecting part is provided with a clamping interface, and the connecting part is also provided with a circumferential limiting structure, so that the crochet hook is prevented from rotating along
