Embodiment Construction

[0025] figure 1 A side sectional view of an electric storage superfinishing machine 10 is shown, which has 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 .

[0026] 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 grinding tool (10) comprises a housing (12), wherein a grinding plate (30) having a grinding sheet (56) which is driven by an angular gear (37) is moveably arranged on lower side surface of the housing; the angular gear (37) is formed by an eccentric machine (34) which drives a swinging rod (42) to have reciprocating motion around a swinging shaft (44); the swinging shaft (44) is extended by being parallel with the grinding plate (30); the swinging rod (42) is arranged as an angular rod; one rod arm thereof has reciprocating motion from up to down around the swinging shaft (44); and the other rod arm is rotated for an angle downwards and transmits the back and forth reciprocating motion along the horizontal direction to the grinding plate (30) or other tools.

Description

[0001] This application is a divisional application of a patent application with an application date of December 22, 2004 and an application number of 200410103732.X. technical field [0002] The invention relates to a hand-held power tool. Background technique [0003] EP 0224465 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 [0004] According to the invention, a hand-held power tool is proposed, which has a ...
