Embodiment Construction

[0024] FIG. 1 shows a side sectional view of an electric storage superfinishing machine 10 with a flat, narrow, box-shaped housing 12 . It serves as a handle, and the operating hand is placed on the upper surface 11 of the housing 12 in such a way that the front side 14 of the housing points in the feed direction and a switch key 16 located on the front side 14 of the housing 12 can be comfortably Touch it with your hands. An electrical on and off switch 17 located in the housing 12 can be actuated via this switch key 16 .

[0025] On the back side 18 of the casing 12, two insertion openings 20 are arranged parallel to the upper surface 11 for the insertion of two accumulators. . Arranged within the housing 12 is an electric motor 24 , in particular a DC motor, which is mounted in a base 26 . The base 26 is coupled downwardly via an elastic support ring 28 to a grinding disc 30 which engages in its grinding disc 31 so that it cannot be lost.

Abstract

A hand-held power tool (10) has a housing (12), on the lower side of which a grinding blade (56) is movably arranged, which can be passed through an angle transmission device (37 ) A grinding disc (30) driven by an electric motor, wherein the angular transmission (37) consists of an eccentric (34) that drives a swing rod (42) to reciprocate around a swing axis (44). The swing axis (44) extends parallel to the grinding disc (30), wherein the swing link (42) is constructed as an angle bar, one of its lever arms moves up and down around the swing axis (44), and its other lever arm moves toward the The lower deflection is angled and imparts a horizontal back and forth reciprocating motion to the grinding disc (30) or one other tool.

Description

technical field [0001] The invention relates to a hand-held power tool. Background technique [0002] EP 0 224 465 discloses a hand-held power tool in which the rotational movement of a drive motor is converted into a rotational pivoting movement of its output shaft. Simultaneously, a grinding tool, such as a grinding disc, connected together with the output shaft performs a rotational oscillating motion synchronously with the output shaft. This movement has a defined frequency and a defined reciprocating rotational path, which makes the operation of the power tool and the control of the tool guide reliable and precise. Here, the tool cannot obtain the linear motion produced by the electric motor. Contents of the invention [0003] According to the invention, a hand-held power tool is proposed, which has a housing, on the underside of which is movably mounted a grinding disc-carrying device that can be driven by an electric motor via an angular drive (Winkelgetriebe).
