Description

Coil skeleton frame assembly

Technical Field

The utility model relates to a motor part, especially a coil skeleton subassembly.

Background

The coil framework process flow comprises the following steps: assembling an upper framework, a lower framework and a middle polar plate, inserting a pin, winding, pressing and loosening the pin for the second time, coating tin (reserving the wire and coating the tin depth), welding a circuit board assembly, installing a wire protection box, installing a shell, installing a gear and the like.

The existing upper framework structure is of an integrated structure, problems difficult to avoid and control exist in an assembly process, a reserved line is reserved before tin coating due to the fact that a circuit board exists, the length of the reserved line is difficult to control on a production line due to the fact that a line head part is not tightened when secondary needle pressing is conducted and the reserved line is difficult to control on the production line after tin coating is conducted, the reserved line is easy to press into a needle hole during secondary needle pressing, and an enamelled bag is damaged or even broken due to the fact that the reserved line is required to be 2 ~ 4 circles, tin coating depth must be strictly controlled, and the phenomenon difficult to solve is caused due to factors such as automation input degree, automation equipment precision and cost during actual operation.

Disclosure of Invention

the utility model relates to a coil skeleton subassembly goes up the skeleton and is split type design, can effectively solve current structure in the welding, reserves the line, and the control difficult point on technologies such as tin depth is warded off to the line.

in order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a coil skeleton subassembly, includes skeleton, last skeleton, well polar plate and contact pin down, all be equipped with the skeleton hole on skeleton and the last skeleton down, well polar plate installs at the skeleton downtheholely, it includes skeleton body and gear-rack to go up the skeleton, upward be equipped with the mounting groove on the skeleton body, the cell wall of mounting groove is equipped with first latch, is equipped with the second latch that clamps with first latch on the gear-rack, and the gear-rack cartridge is in the mounting groove to block through first latch and second latch is fixed.

The first latch and the second latch are provided with a plurality of teeth, and the tooth pitch is equal.

The lower part of the upper framework is provided with four positioning columns which are fixedly connected with holes of the lower framework.

The middle polar plate is formed by fixing two polar plates which are symmetrical and arranged in opposite directions.

After the structure of the oil adding device is adopted, the utility model discloses an go up the skeleton and be split type structural design, constitute including picture pin seat and last skeleton body, and picture pin seat and last skeleton body clamp for through first latch and second latch. During installation, the needle inserting seat and the upper framework body are not required to be clamped in place, a gap with a tooth pitch is reserved for winding, and the needle inserting seat and the upper framework body are inserted in place after winding, so that the purpose of loosening the threads is achieved. By adopting the structure, secondary needle pressing is not needed, the tin coating depth can relax the control requirement, and the scheme can well solve the problems of hidden danger and difficult solution caused by the process structure of the existing product.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrated in the accompanying drawings.

Referring to fig. 1-5, a coil frame assembly includes a lower frame 1, an upper frame 2, a middle pole plate 3 and a contact pin 4, wherein frame holes 5 are formed in the lower frame 1 and the upper frame 2, the middle pole plate 3 is installed in the frame holes 5, the upper frame 2 includes an upper frame body 21 and a contact pin seat 22, an installation groove 23 is formed in the upper frame body 21, a first contact pin 24 is arranged on a groove wall of the installation groove 23, a second contact pin 25 clamped with the first contact pin 24 is arranged on the contact pin seat 22, and the contact pin seat 22 is inserted in the installation groove 23 and fixed through the clamping of the first contact pin 24 and the second contact pin 25.

Referring to fig. 4 and 5, the first latch 24 and the second latch 25 are provided in three numbers, and the pitches are equal. When the first latch 24 and the second latch 25 are matched, 2 tooth pitches are clamped firstly, one tooth pitch is reserved, and then winding is carried out, so that the operation is simple.

Referring to fig. 1, the lower portion of the upper frame 2 is provided with four positioning pillars 26, and the positioning pillars 26 are fixedly connected with holes of the lower frame 1. Before the upper framework 2 and the lower framework 1 are fixed, the four positioning columns 26 are used for positioning, and then the fixing is carried out.

Referring to fig. 1, the middle pole plate 3 is formed by fixing two pole plates which are symmetrical to each other and arranged in opposite directions. The pole plate is mainly used for winding after being fixed.

Referring to fig. 1-5, the present invention comprises a lower frame 1, an upper frame 2, a middle pole plate 3 and a pin 4. Firstly, the lower framework 1, the upper framework 2 and the middle pole plate 3 are fixed in sequence, then the contact pin 4 is inserted into the contact pin seat 22, the contact pin seat 22 is clamped on the upper framework body 21, and a tooth pitch is reserved firstly when the first clamping tooth 24 and the second clamping tooth 25 are matched, and then winding is carried out, as shown in fig. 2. And then the wire is wound on the contact pin 4, the contact pin seat 22 is completely clamped in the mounting groove 23 of the upper framework body 21, and the wire is naturally loosened after the mounting is in place, so that the wire loosening purpose is realized. Finally, the needle bending operation is performed, as shown in fig. 3. Therefore, secondary needle pressing is not needed, the tin coating depth can relax the control requirement, and the scheme can well solve the problems of hidden danger and difficulty in solving caused by the existing product process structure.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
