Description

直流无刷电机霍尔装置装配结构
技术领域
本发明涉及一种直流无刷电机霍尔装置装配结构，属于电机生产制造的 技术领域。
背景技术
现有技术中，直流无刷电机定子的线圈骨架与安装有霍尔的线路板之间 通常设置相应的安装孔，再通过螺钉将定子的线圈骨架与线路板安装固定在 一起。然而， 该种结构中的线路板直径通常仅略小于机壳内径， 而线圈骨架 则通常位于机壳内，在进行线路板与线圈骨架的装配时， 需将线路板上的安 装孔与线圈骨架上的安装孔对准才能装配螺钉，但由于线路板与机壳内径相 差不大， 故线路板在机壳的转动并不容易， 从而导致了线路板的安装孔与线 圈骨架上的安装孔对准较困难， 导致了线路板与线路板之间的装配速度较 慢， 生产效率较低； 同时， 由于线路板的材质问题， 在通过螺钉安装时， 往 往可能会因为对螺钉的拧紧过度或其它情形造成线路板设置安装孔的部位 开裂， 从而造成对线路板的固定不可靠， 或导致线路板报废等问题。
发明内容
本发明目的在于提供一种易于将线路板的安装孔和线圈骨架的安装孔 对准， 装配方便， 利于提高生产效率， 可保证线路板对应于安装孔的部位不 开裂， 防止线路板因开裂而报废的直流无刷电机霍尔装置装配结构，解决了 现有技术存在的在进行线路板与线圈骨架的装配时，需将线路板上的安装孔 与线圈骨架上的安装孔对准才能装配螺钉，但由于线路板与机壳内径相差不 大， 故线路板在机壳的转动并不容易，从而导致了线路板的安装孔与线圈骨 架上的安装孔对准较困难， 导致了线路板与线路板之间的装配速度较慢， 生 产效率较低， 及由于线路板的材质问题， 在通过螺钉安装时， 往往可能会因 为对螺钉的拧紧过度或其它情形造成线路板设置安装孔的部位开裂，从而造 成对线路板的固定不可靠， 或导致线路板报废等问题。
本发明的上述技术目的是通过以下技术方案解决的： 它包括线路板，通 过霍尔引脚焊接固定在线路板上的霍尔及与定子冲片固定的线圈骨架，其特 征在于所述线圈骨架外圈端部和线路板之间形成相互配合的安装孔，所述线 路板对应于安装孔部位至少一个表面嵌设有金属片， 所述安装孔穿过金属 片；所述线圈骨架外圈端部还形成有预定位销，所述线路板上设有与预定位 销相应的预定位孔。在进行线路板和线圈骨架的装配时， 只需先将线路板上 的预定位孔与线圈骨架上的预定位销对准配合在一起，即可实现线路板上的 安装孔与线圈骨架上的安装孔之间的对准， 从而进行螺钉的装配，装配非常 方便， 利于提高生产效率； 其中， 在线路板上对应于安装孔的部位嵌设金属 片，在拧紧螺钉时可防止因对螺钉的拧紧过度而导致线路板开裂，从而减少 了线路板的报废， 保证了线路板的可靠固定。
作为优选，所述线路板对应于安装孔部位的上、下表面分别嵌设有金属 片。其中， 在线路板对应于安装孔部位的上、 下表面分别嵌设金属片可进一 步保证线路板安装孔部位的牢固性， 防止开裂， 保证线路板固定可靠。
作为优选，所述预定位孔的孔径大于预定位销的直径，所述预定位销端 部呈锥台结构。其中， 将预定位孔的孔径设计成大于预定位销的直径， 一方 面可方便于预定位孔和预定位销之间的配合，另一方面可便于线路板与线圈 骨架之间圆周方向上的微调，从而克服引加工误差等因素造成线路板上的安 装孔和线圈骨架上的安装孔的轻微错位问题，便于线路板和线圈骨架之间的 装配； 当配合时预定位销与线路板上的预定位孔存在轻微的错位时，预定位 销端部的锥台结构能使预定位销滑入线路板的预定位孔内，从而便于线路板 与线圈骨架之间的装配。 作为优选，所述线圈骨架外圈端部形成若干等高的弧形厚凸块和弧形薄 凸块，所述线圈骨架上的安装孔及预定位销均分别形成于厚凸块上和薄凸块 上；所述厚凸块的厚度大于所述薄凸块的厚度，所述厚凸块的厚度与线圈骨 架外圈的壁厚相等， 所述薄凸块的厚度为线圈骨架外圈壁厚的一半。 其中， 由于预定位销仅起到预定位的作用，故可以将预定位销所在的位置设计成厚 度较薄的薄凸块，而线圈骨架安装孔所在的位置需起到主要的对线路板的固 定作用，故需要其设计成厚度较厚的厚凸块，以加强对线路板固定的可靠性。
因此，本发明具有易于将线路板的安装孔和线圈骨架的安装孔对准， 装 配方便， 利于提高生产效率， 可保证线路板对应于安装孔的部位不开裂， 防 止线路板因开裂而报废等特点。
