为了使本发明的目的、技术方案及优点更加清楚明白，下面结合附图及实施例对本发明作进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
一种快修式电机壳体，包括：主壳体1，壳体盖2，其中壳体盖2设置在主壳体1上，壳体盖2和主壳体1构成安装在电机端部的壳体，壳体盖2设置有第一配合部3，主壳体1设置有第二配合部4，第一配合部3与第二配合部4可相互配合，用于支撑和定位壳体盖2和主壳体1之间的相对位置。壳体盖2设置有第一锁定部5，主壳体1设置有第二锁定部6，壳体盖2依靠锁定部与主壳体1连接固定。
请参阅图1-3，一种快修式电机壳体，包括：主壳体1，壳体盖2，其中壳体盖2设置在主壳体1上，壳体盖2和主壳体1构成壳体，具体为：
壳体盖2为碗状，壳体盖2的碗口一侧设置有环形凸台，该凸台内侧为轴承配合面9，该凸台的外侧为壳体盖2的第一配合部3，主壳体1设置有第二配合部4，该第二配合部4为与第一配合部3相对应的带有孔的凹口，该凹口的形状尺寸与壳体盖2的碗口相同，凹口的孔其尺寸与形状与凸台相同，第一配合部3与第二配合部4可相互配合，本实施例中，第一配合部3与第二配合部4为轴-孔配合。
当然，上述实施例中，壳体盖2的配合面可设置为凹口，主壳体1的配合面设置为凸台，此外，第一配合部3与第二配合部4还可以销钉配合、螺纹配合或平面配合，且第一配合部3与第二配合部4还可根据需要设计为圆形、弧形、方形或多边形等形状，壳体盖2可以为平板、碗状或杯状等多种形状。
壳体盖2设置有第一锁定部5，该第一锁定部5为通孔，该第一锁定部5围绕壳体盖2的轴心成环形等距布置，主壳体1设置有第二锁定部6，该第二锁定部6为螺丝孔，第二锁定部6的螺丝孔数量与第一锁定部5的通孔相同且位置对应，壳体盖2的第一锁定部5依靠螺丝11与主壳体1连接 的第二锁定部6固定。
当然，壳体盖2与主壳体1的锁定方式可以有其它方案，如第一锁定部5和第二锁定部6的锁定方式可以为卡口锁定、卡扣锁定或螺纹配合锁定等。
在本发明的一个特殊实施例中，壳体盖2与主壳体1的锁定部和配合部可以一体化设计，如在壳体盖2的凸台外侧设置外螺纹，在主壳体1的凹口的孔上设置内螺纹，通过螺纹配合的方式，实现壳体盖2与主壳体1的锁定和配合。此时，应在壳体盖2上设置花键、旋转孔、十字槽等方式，方便壳体盖2的安装与锁定。
壳体盖2靠近边缘位置还可设置有拆卸螺纹孔、楔形口7或防滑纹，本实施例中，壳体盖2边缘设置有楔形口7，主壳体1的对应位置设置有凹槽8，且楔形口7与凹槽8位置对应，通过凹槽8为插入楔形口7的工具提供插入空间，具体的，在拆卸时，将一字螺丝刀由凹槽8插入楔形口7，一字螺丝与凹槽8的边缘形成杠杆，通过撬动将壳体盖2取出。
当然，若拆卸设计为螺纹孔，通过螺丝顶起的方式，拆卸壳体盖2，在此不加以限制。
为保证壳体的密封性，在壳体盖2与主壳体1之间设置有密封圈，该密封圈可以为平面压紧或环抱的方式实现密封，当然密封也可采用涂抹硅胶等方式来实现，在此不加以限制。
为方便设置密封圈、壳体盖2还设置有裙边10，裙边10外形尺寸大于主壳体1上的与壳体盖2相对应的开孔或开口的尺寸。
在一实施例中，如图4所示，壳体盖2为杯状，壳体盖2的杯口一侧设置有环形凸台，该凸台的外侧为壳体盖2的第一配合部3，主壳体1设置有第二配合部4，该第二配合部4为与第一配合部3相对应的带有孔，孔的尺寸与形状与凸台相同，第一配合部3与第二配合部4可相互配合，本实施例中，第一配合部3与第二配合部4为轴-孔配合。
当然，上述实施例中，壳体盖2的配合面可设置为凹口，主壳体1的 配合面设置为凸台，此外，第一配合部3与第二配合部4还可以销钉配合、螺纹配合或平面配合，且第一配合部3与第二配合部4还可根据需要设计为圆形、弧形、方形或多边形等形状，壳体盖2可以为平板、碗状或杯状等多种形状。
壳体盖2设置有第一锁定部5，该第一锁定部5为通孔，该第一锁定部5围绕壳体盖2的轴心成环形等距布置，主壳体1设置有第二锁定部6，该第二锁定部6为螺丝孔，第二锁定部6的螺丝孔数量与第一锁定部5的通孔相同且位置对应，壳体盖2的第一锁定部5依靠螺丝11与主壳体1连接的第二锁定部6固定。
当然，壳体盖2与主壳体1的锁定方式可以有其它方案，如第一锁定部5和第二锁定部6的锁定方式可以为卡口锁定、卡扣锁定或螺纹配合锁定等。
通过将壳体盖2设置成杯状，在对壳体盖2进行拆卸时，作业员对螺丝进行拆卸后，手握壳体盖2对其进行晃动，即可方便的将壳体盖2拔出，方便更换零件。
为保证壳体的密封性，在壳体盖2与主壳体1之间设置有密封圈，该密封圈可以为平面压紧或环抱的方式实现密封，当然密封也可采用涂抹硅胶等方式来实现，在此不加以限制。
通过上述结构，在电机损坏后，可以通过对壳体盖2进行拆除，进而对电机内部进行检查和维修，无需将电机的整个壳体进行拆除。
本发明取得的有益效果：
1)通过将壳体分为主壳体和壳体盖，无需整体拆解电机，方便维护人员维护。
2)通过设置密封，保持电机的密闭，不破坏电机原本的密封性，防水防尘提高电机寿命。
3)通过设计易拆结构，方便壳体盖的拆解，减少修理时间，提高维护效率。
以上仅为本发明的较佳实施例，并非用来限定本发明的实施范围；如果不脱离本发明的精神和范围，对本发明进行修改或者等同替换，均应涵盖在本发明权利要求的保护范围当中。
