Its main function is to help operators complete the winding work more efficiently and accurately, ensure the neatness, tightness and standardization of the winding, and improve production efficiency and product quality.

[0006] Preferably, the limiting assembly 1 includes a positioning block 1, the outer wall of the positioning block 1 is fixedly connected to the outer wall of the clamping block 1, the inner wall of the clamping block 2 is provided with a positioning groove 2, the outer wall of the positioning block 1 is arranged on the side wall of the clamping block 2 through the positioning groove 2, the upper surface of the positioning block 1 is arranged inside the coil fixing frame through the limiting groove, and the outer wall of the limiting block 1 is fixedly connected to the outer wall of the positioning block 1.

[0007] Preferably, the second limiting component includes a second positioning block, the outer wall of the second positioning block is fixedly connected to the outer wall of the second clamping block, the inner wall of the first clamping block is provided with a first positioning groove, the outer wall of the second positioning block is arranged on the side wall of the first clamping block through the first positioning groove, the lower surface of the second positioning block is arranged inside the coil fixing frame through the limiting groove, and the outer wall of the second limiting block is fixedly connected to the outer wall of the second positioning block.

[0008] Preferably, a clamping groove 1 is provided on the side wall of the clamping block 1, and the clamping block is arranged inside the clamping block 1 through the clamping groove 1.

[0009] Preferably, four slots 1 are evenly formed on the side wall of the clamping block 1.

[0010] Preferably, a second clamping groove is provided on the side wall of the second clamping block, and the clamping block is arranged inside the second clamping block through the second clamping groove.

[0011] Preferably, four second clamping grooves are evenly formed on the side wall of the clamping block 2.

[0012] Preferably, the gland contains a structural layer inside, the outer wall of the structural layer is fixedly connected to a buffer layer, and the outer wall of the buffer layer is fixedly connected to an insulating layer.

[0013] Preferably, the structural layer is made of aluminum alloy, and the buffer layer is made of rubber.

[0014] Preferably, the insulating layer is made of polycarbonate.

[0015] Working principle: Wind the enameled wire around the coil fixing frame, align the positioning block one with the positioning slot two and insert the positioning block one into the positioning slot two, and align the positioning block two with the positioning slot one and insert the positioning block two into the positioning slot one. At this time, the positioning block one and the positioning block two pass through the limiting slot and are stuck in the inside of the coil fixing frame. Then the clamping block one and the clamping block two provide support for the coil fixing frame through the positioning block one and the positioning block two, and the clamping block is clamped into the clamping slot one, and then the pressure cover is clamped into the inside of the clamping block one, and at the same time, the clamping block is clamped into the clamping slot two, and then the pressure cover is clamped into the inside of the clamping block two. When the coil fixing frame needs to be inspected, the clamping block one, the clamping block two and the pressure cover can be quickly removed from the surface of the coil fixing frame by pulling the pressure cover outward, thereby reducing the labor intensity of the staff, avoiding damage to the enameled wire due to unnecessary friction and collision, and ensuring the integrity of the enameled wire.

[0016] The clamping block 1 and the clamping block 2 are connected together by the positioning block 1 and the positioning block 2, and then further fixed under the positioning of the pressure cover. The installation position of the clamping block 1 and the clamping block 2 is quickly and accurately determined. At the same time, the clamping block 1 and the clamping block 2 are spliced ​​to ensure that the enameled wire can be wound according to the preset path and position, thereby simplifying the installation process, saving the time and energy consumed by the operator for repeated debugging and calibration, and avoiding the effect of deviation in the winding position.

[0017] The gland is formed by stacking multiple layers of materials, which are composed of a structural layer, a buffer layer and an insulating layer. The structural layer is made of aluminum alloy, which is a light metal material with the characteristics of high strength, high hardness and good thermal conductivity. This enables the gland to keep the coil fixing frame stable and prevent heat accumulation from affecting the performance of the enameled wire by rapid heat dissipation. The buffer layer is composed of rubber, which is a polymer material with good elasticity and flexibility. It can play a buffering role in the winding process to prevent the outer skin of the enameled wire from being damaged. The insulating layer is composed of polycarbonate, which is a high molecular polymer with good insulating properties. This enables the gland to prevent current leakage of the enameled wire, thereby resisting external collisions, scratches and impacts, preventing the enameled wire from being damaged, dissipating heat evenly, avoiding local accumulation of heat, preventing the enameled wire from overheating and causing performance degradation and shortening of life, and effectively preventing current leakage.

[0018] The present invention provides a winding clamp with a self-locking function. It has the following beneficial effects:

[0019] 1. The present invention winds the enameled wire around the coil fixing frame, aligns the positioning block 1 with the positioning groove 2 and inserts the positioning block 1 into the positioning groove 2, and aligns the positioning block 2 with the positioning groove 1 and inserts the positioning block 2 into the positioning groove 1, and the clamping block 1, the clamping block 2 and the pressure cover can be quickly removed from the surface of the coil fixing frame by pulling the pressure cover outward, so as to achieve the effect of quickly disassembling and assembling the winding fixture, reduce the labor intensity of the staff, avoid the damage of the enameled wire due to unnecessary friction and collision, and ensure the normal operation of the motor.

[0020] 2. The present invention uses the common positioning of positioning block 1, positioning block 2 and the pressure cover to quickly and accurately determine the installation positions of clamping block 1 and clamping block 2, ensuring that the enameled wire can be wound according to the preset path and position, thereby simplifying the installation process, saving the time and energy consumed by the operator, and avoiding deviations in the winding position.

[0021] 3. The present invention adopts a multi-layer material stacking combination to form a gland, which is composed of a structural layer, a buffer layer and an insulating layer. The structural layer is made of aluminum alloy, the buffer layer is made of rubber, and the insulating layer is made of polycarbonate. This can achieve the effect of resisting external collisions, scratches and impacts, preventing the enameled wire from being damaged, dissipating heat evenly, avoiding local accumulation of heat, preventing the enameled wire from overheating and causing performance degradation and shortening of life, and effectively preventing current leakage.
