Abstract

一种直型动力研磨机，其包括细长壳体(10)，壳体后端具有带动力控制装置(14，15)的手柄(11)，前端具有支撑与旋转电机相连的输出轴(17)的颈部部分(12)。颈部部分(12)为砂轮保护罩(20)形成了整合的固定法兰(18)，其中颈部部分(12)和固定法兰(18)构成了在操作过程中作为研磨机的舒适手动支撑的辅助手柄。

Description

具有砂轮保护罩和辅助手柄的便携式研磨机
技术领域
本发明涉及一种便携式动力研磨机，该研磨机包括壳体、旋转电机、安装砂轮的输出轴和安装在壳体上的砂轮保护罩。特别是，本发明涉及一种包括细长壳体的直型动力研磨机，输出轴从壳体前端伸出。
背景技术
直型便携式研磨机包括后端装有手柄和动力控制装置(例如气动工具情形下的节流阀)的壳体。但是，为了获得对该工具的良好控制并且能够在该工具上施加进给力，操作者也使用壳体的前端作为辅助手柄。通常将砂轮保护罩安装在壳体的同轴颈部部分，并通过紧固装置使之牢固。这造成辅助手柄相当不符合人体工学，因为紧固装置具有锋利的边缘，完全不适合作为手柄的一部分。因此，对操作者来说使用壳体前端作为手柄很不舒适。
发明内容
本发明的主要目的是制造一种改进的直型动力研磨机，其壳体上所带的砂轮保护罩固定装置为在操作过程中对研磨机进行更好的手动控制提供了更加舒适的辅助手柄。
本发明的另一目的是提供一种带砂轮保护罩固定装置的动力研磨机壳体，该保护罩固定装置构成辅助手柄的一部分并提供可选择的砂轮保护罩安装位置。
本发明的更多的性能特征和优点将体现在在下面的说明书和权利要求书中。
附图说明
下面参照附图详细描述本发明的优选实施例。
图中：
图1示出了依据本发明的动力研磨机的侧视图。
图2示出了图1中的研磨机的前视图。
具体实施方式
附图所示动力研磨机是包括细长壳体10的气动研磨机，壳体后端具有手柄11，前端具有管状颈部部分12。手柄11具有压缩空气管道连接件13和由控制杆15操纵的节流阀14。该研磨机还包括未示出的驱动地连接到输出轴17的旋转电机，输出轴17被同轴轴颈支撑在颈部部分12中。输出轴17在壳体10的前端突出出来，用于带动砂轮。
在壳体10的前端，并形成为颈部部分12的整合部分，为砂轮保护罩20设置了具有平的前端安装面19的固定法兰18。固定法兰18在颈部部分12的主要部分周围延伸，但是留出砂轮保护罩20对面的部分以免在操作过程中干扰工作部件。砂轮保护罩20具有四个用来与固定法兰18上相应的钻孔23啮合的固定螺钉22a-d。见图2。固定法兰18上钻孔23的数目多于螺钉22a-d，以便砂轮保护罩20能够安装在相对于壳体10的至少两个可选择的角位置。
固定法兰18与颈部部分12共同构成辅助手柄26，法兰18具备锥面25，以便为操作者构成舒适的握把和轴向的手部支持装置。在此类型动力研磨机中，在两个不同位置的操作过程中，即在壳体后端通过手柄和在壳体前端通过壳体的前端颈部部分，允许工具的手动支持是非常必要的。根据本发明这是由颈部部分12与径向砂轮保护罩固定法兰18联合实现的，固定法兰18与颈部部分12整合在一起，并通过它的锥面25构成辅助手柄26的舒适性加强部分。
