Description

Replacement structure of coil core of needle selector

The invention relates to a needle selector, in particular to a coil core replacement structure of the needle selector.

The conventional needle selector shown in FIG. 3 includes a base 5 with a front end integrally extending a mounting base 51 for a plurality of coil iron cores 6, wherein the base 5 corresponds to each coil iron core. 6 is provided with a positioning slot 52 for the coil core 6 to extend into position, and a circuit board 7 is electrically connected to each coil core 6, and the circuit board 7 is fixed to the base 5 and pressed in each position The slot 52 is used to fix each coil core 6.

The aforementioned needle selector is a precise machine. The position of each coil iron core 6 must be accurately set, and it must be well fixed to avoid its displacement, so as to be properly driven. However, in the conventional structure, all the coil cores 6 are pressed and fixed by the same circuit board 7. As long as one of the coil cores fails, the circuit board 7 must be detached to replace the target core. However, at this time, The other coil cores will lose the fixing effect, and may be deviated from the original position. As a result, maintenance personnel must additionally correct the positions of all cores, increasing their work load and man-hours required for maintenance.

In addition, the mounting base 51 is integrally made from the front end of the base 5 using wire cutting technology, which is difficult to manufacture and costs are high. If part of the mounting base 51 is damaged, the entire base 5 must be And replacement, causing unnecessary waste of materials and maintenance costs.

In view of this, how to improve the above problems is the primary problem to be solved by the present invention.

The main object of the present invention is to provide a coil core replacement structure of a needle selector, in which the coil core is separately fixed by a plurality of fixing members, and during maintenance, the fixing member can be detached only for the target core to be replaced. The purpose is to avoid affecting other cores.

In order to achieve the foregoing object, the present invention provides a coil iron core replacement structure of a needle selector, which includes: a base, one end of which is provided with a detachable mounting base, the mounting base is provided with a plurality of mounting slots, each of which is installed The slot is provided with a coil core respectively; the base is provided with a positioning slot corresponding to each mounting slot for the coil core to extend into position; a plurality of fixing members, which are fixed on the base, and each fixing member is respectively pressed on A part of the positioning groove; (1) a circuit board, which is fixed on the base and is electrically connected with each coil core;

In one embodiment, each fixing member is pressed on one or more positioning grooves; further, each fixing member is defined as being pressed on two positioning grooves.

In an embodiment, a cushion body is provided in each mounting groove to fill the gap between the coil core and the mounting groove.

In one embodiment, each fixing member is fixed on the base by screws.

In an embodiment, the circuit board is provided with a recessed portion corresponding to each fixing member, so that each fixing member is disposed in the recessed portion.

The above-mentioned objects and advantages of the present invention can be easily understood from the detailed description and accompanying drawings of selected embodiments below.

Please refer to FIGS. 1 and 2, which shows a coil core replacement structure of the needle selector provided by the present invention, which includes a base 1, and the base 1 is provided with a circuit board 11. A mounting base 2 is provided at one end of the base 1. The mounting base 2 is made of a metal material and is fixed to the base 1 with screws 23. It can be detached when needed. The mounting base 2 is provided with a plurality of mounting grooves 21, and each mounting groove 21 is respectively provided with a cushion body 22, such as foam or rubber, and a coil core 3, wherein the coil core 3 is composed of a long core rod. 31 is formed by winding a coil 32 at one end, and is fixed in the mounting groove 21 by the pad body 22, and the coil core 3 is electrically connected to the circuit board 11, which can generate a magnetic field after being energized to drive the selector Generate action. A positioning slot 12 is provided at one end of the base 1 near the mounting seat 2 corresponding to each of the mounting slots 21, for each coil iron core 3 to extend into one position.

In this embodiment, the base 1 is further provided with a circuit board 13 that can be plugged and fixed from the top to the bottom. By the configuration of the installation orientation, the installation and maintenance of the circuit board 13 can be more convenient.

On the bearing, the base 1 is provided with a plurality of fixing members 4, each of the fixing members 4 is respectively located above a part of the positioning groove 12, and is fixed to the base 1 with a screw 41 to suppress the positioning groove 12, The coil core 3 is fixed in the slot. Each fixing member 4 is a square plate, which has a certain area, and can be extended to the range of more than one positioning groove 12. In this embodiment, it is further defined that each fixing member 4 can be extended to two. Range of positioning groove 12. According to this, each of the fixing members 4 can press the two positioning slots 12 respectively, so that the coil core 3 in the two positioning slots 12 is fixed.

On the other hand, the circuit board 11 is provided with a recessed portion 11 at a position corresponding to each of the fixing members 4, so that each fixing member 4 can be disposed on the base 1 at a position corresponding to the recessed portion 111, so that each of the fixing members 4 Disassembly does not affect the circuit board 11.

With the above structure, the coil core 3 on the mounting base 2 is respectively fixed by a plurality of fixing members 4. When a part of the coil core 3 fails and needs to be repaired and replaced, it is only necessary to detach the corresponding fixing member 4 The faulty coil core can be replaced, and the other coil cores are still being pressed to fix their positions because their corresponding fixing parts have not been removed, so they are not affected by maintenance operations and cause their position to deviate. According to this, after the replacement of the new coil core by the maintenance personnel, it is only necessary to recalibrate the coil core to which the newly detached fixing part belongs, without having to calibrate other coil cores, thereby reducing the technical difficulty and saving. Purpose of maintenance work.

In addition, if the mounting base 2 is damaged, it can also be detached separately to replace it with a new one. In addition to convenient maintenance, it has the advantage of reducing maintenance costs.

However, the disclosure of the above embodiments is only used to illustrate the present invention and is not intended to limit the present invention. Therefore, the replacement of equivalent components should still belong to the scope of the present invention.

In summary, those skilled in the art can understand that the present invention can indeed achieve the aforementioned purpose, and it has indeed complied with the provisions of the Patent Law, and filed an application in accordance with the law.
