no. 1 Embodiment approach

[0062] Such as figure 1 As shown, the grinder 1 of this embodiment is a hand-held electric tool (so-called disc grinder) for machining a workpiece by rotating a disc (disc)-shaped tip tool 6 . Here, machining includes grinding, lapping, cutting, and the like.

[0063] The grinding machine 1 has a motor housing 2 and a gear housing 4 as the housing of the main body of the grinding machine.

[0064] The motor case 2 is used to accommodate the motor, and is a substantially cylindrical case that can be held by the user. The rotation shaft of the motor protrudes toward the gear housing 4 disposed in front of the motor housing 2 .

[0065] In addition, a rear cover is provided on the opposite side of the gear case 4 , that is, behind the motor case 2 , and a drive circuit of the motor and the like are housed inside the rear cover.

[0066] The gear housing 4 is provided to close the front opening of the motor housing 2 . Inside the gear housing 4 is accommodated a gear mechanism...

no. 2 Embodiment approach

[0108] Next, the grinding wheel cover 8A of the second embodiment will be described.

[0109] The basic structure of the grindstone cover 8A of this embodiment is the same as that of the grindstone cover 8 of the first embodiment, but the structures of the second cover 30A and the engaging member 40A are different from those of the first embodiment. In the following description, this point of difference will be described. Regarding the second cover 30A and the engaging member 40A, the same drawing with the suffix A attached to the part corresponding to the first embodiment is described in the drawing. mark, and some descriptions are omitted.

[0110] In the grinding wheel cover 8A of this embodiment, like the first cover 10, the second cover 30A and the engaging member 40A are formed of metal plates.

[0111] Such as Figure 6 - As shown in FIG. 9 , a bent portion 38A is provided on one end side in the outer peripheral direction of the second outer peripheral protection port...

no. 3 Embodiment approach

[0129] Next, the grinding wheel cover 8B of the third embodiment will be described.

[0130] The basic structure of the grindstone cover 8B of this embodiment is the same as that of the grindstone cover 8 of 1st Embodiment, and the structure of the 2nd cover 30B and the engaging member 40B differs from 1st Embodiment. In the following description, this point of difference will be described. Regarding the second cover 30B and the engaging member 40B, the same drawing with the suffix B attached to the part corresponding to the first embodiment will be described. mark, and some descriptions are omitted.

[0131] In the grindstone cover 8B of this embodiment, like the grindstone cover 8A of the first embodiment, the second cover 30B and the engaging member 40B are formed of metal plates.

[0132] Such as Figure 10 ~ Figure 1 3, a bent portion 38B is provided on one end side in the outer peripheral direction of the second outer peripheral protection portion 31B, and an engaging ...

Abstract

Provided is a wheel cover having a first cover which is mounted to an electric tool body and having a second cover which is removably mounted to the first cover, wherein rattling of the second cover is prevented. This wheel cover has: a first cover mounted to an electric tool body and covering at least a part of a first surface, i.e., the electric tool body-side surface of a front end tool; a second cover removably mounted to the first cover and covering at least a part of a second surface, i.e., the surface of the front end tool, which is located on the side opposite the electric tool body; and a rattling prevention section for preventing the second cover from rattling relative to the first cover while the second cover is mounted to the first cover.

Description

technical field [0001] The present invention relates to a grinding wheel cover used to cover a tip tool in an electric power tool that rotates a disc-shaped tip tool to perform machining. Background technique [0002] When turning the tip of an electric power tool to machine a workpiece, a wheel cover is used to suppress sparks and dust from flying. If the area covering the tip tool is increased to increase the effect of suppressing spatter, the grinding wheel cover may interfere with the workpiece during processing, and the processing capability of the power tool to process the workpiece may be reduced. [0003] Therefore, in order to prevent the grinding wheel cover from interfering with the workpiece during the machining operation of the workpiece, it is preferable to change the area where the grinding wheel cover covers the tip tool according to the type of tip tool (in other words, machining operation). [0004] For example, in the case of grinding / grinding a workpiece...
