Description

Technical Field

[0001] This utility model relates to a fast-adjusting winding die mechanism, belonging to the field of winding die technology. Background Technology

[0002] In the manufacturing process of micro-motor windings, winding dies and winding machines are indispensable equipment. The dimensions of the winding die determine the coil dimensions, which in turn must be matched to the stator core. Existing technology, such as the winding die disclosed in patent publication number CN209150956U, relates to the field of motor coil technology and solves the technical problems of difficulty in adjusting the working area height and poor versatility of existing winding dies. This device includes an upper die core, a lower die core, and a gear and rack mechanism. The upper die core is positioned above the lower die core, and the rack in the gear and rack mechanism is connected to both the upper and lower die cores. When rotating, the gear in the gear and rack mechanism can drive the upper and lower die cores to move up and down in a direction closer to or further away from each other. This solution aims to achieve the versatility of winding dies.

[0003] The disadvantage of the aforementioned winding die is that while the winding die teeth are adjusted using a gear and rack mechanism, the rotation of the winding die head is still driven by a motor, which cannot guarantee rotational accuracy. Therefore, we designed a rapid adjustment mechanism for the winding die. Utility Model Content

[0004] The purpose of this invention is to provide a fast-adjusting winding die mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-adjusting winding die mechanism, comprising two winding die heads, a die head connecting seat, a wire reel, and a central connecting rod. The first end of the central connecting rod is connected to the wire reel, and the tail end of the central connecting rod is connected to the die head connecting seat via a bearing. A punch is installed in the middle of the central connecting rod, and a transmission connecting rod is installed through the protruding part of the punch. A first star gear is installed at one end of the transmission connecting rod, and a first sun gear is meshed with the first star gear. The first sun gear is located at one end of the die head connecting seat. A second star gear is installed at the other end of the transmission connecting rod, and a second sun gear is meshed with the second star gear. The second sun gear is located at the end of the punch.

[0006] In the aforementioned quick-adjustment winding die mechanism, a positioning bracket is installed at the other end of the punch, a positioning rod sleeve is installed at one end of the positioning bracket, a positioning rod is installed at one end of the positioning rod sleeve, and a winding positioning head is provided at one end of the positioning rod.

[0007] In the aforementioned rapid adjustment winding die mechanism, a gear positioning sleeve is provided at one end of the second sun gear, and the gear positioning sleeve is connected through the central connecting rod.

[0008] In the above-mentioned quick-adjustment winding die mechanism, a sliding adjustment port is provided at the other end of the die head connecting seat. Two adjustment mounting seats are slidably installed inside the sliding adjustment port, and the two adjustment mounting seats are connected to two winding dies.

[0009] In the aforementioned rapid adjustment winding die mechanism, a pneumatic rail rod is installed between the two adjustment mounting seats, and an inflatable mounting seat is installed at the air hole of the pneumatic rail rod.

[0010] In the aforementioned rapid adjustment winding die mechanism, the central connecting rods all pass through the central holes of the first sun gear and the second sun gear.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model discloses a quick-adjustment winding die mechanism. A punch is installed in the middle of a central connecting rod. A transmission connecting rod is installed through the protruding part of the punch.
