Abstract

PURPOSE:To make it possible to simplify and facilitate grinding work as for wear of a grinding stone by simply advancing a pressing member and comprising a curved portion suitable to this grinding stone and thereby constantly providing a groove width as specified. CONSTITUTION:A disk grinder 1 consists of a metal disk where ultra hard grains are stuck in an electrodeposition method or a similar method. By rotating this disk grinder 1, a workpiece is cut into a groove, the width of which responds to the thickness of the disk grinder 1. The disk grinder 1 is stacked on the side of a revolving flange 2 and fastened with machine bolts 3 or similar means. Pressing members 4 which are designed to press the sides of the disk grinder 1, are installed on the flange 2 near the peripheral edge. When the grinder is subjected to wear, the pressing member 4 is rotated, say, screwed forward from a backward position to an advance position. With this construction, the groove can be so wide as specified, thereby allowing a simpler and easier grinding work.

Description

[Detailed description of the invention] The present invention relates to a rotating disk type grindstone device for groove grinding.

Conventionally, this type of device includes a disc-shaped grinding wheel 1, which is made by bonding carbide abrasive grains to a metal disc by electrodeposition or other means, as shown in the first diagram, for example.
There is a known method in which a groove 0 of a width corresponding to the thickness of the grindstone a is formed on the workpiece b by rotating the grindstone a.
In this case, when the grinding wheel a wears out, the width of the groove 0 decreases accordingly, and thus it is necessary to give the grinding wheel a lateral movement within the groove 0. cannot escape being troublesome.

The purpose of the present invention is to obtain a device free of such inconveniences, and the present invention is made by rotating a disc-shaped grindstone (1) made of a metal disc with cemented carbide abrasive grains bound by electrodeposition or other means. In a type that forms a groove in the workpiece with a width corresponding to the thickness of the grinding wheel (1), there are seven flange (2) rotating the grinding wheel (11).
) is superimposed on the side surface of the whetstone (1) and fixed thereto with a screw (3) or the like, and a pressing member (4) is provided on the seven flange (2) located near the outer peripheral edge and presses the side surface of the grindstone (1). It consists of

Figures 2 to 5 show one example.
and 7 langes (2) are overlapped with each other and fixed to each other by, for example, six screws (3) near the inner peripheral edge, and four pressing members (4) consisting of set screws are attached to the outer peripheral side thereof. We prepared the following. Each pressing member (4) can move forward and backward in each screw hole (5) of the seven twisters (2), and can be rotated with a screwdriver or the like from the state shown in Fig.
It is assumed that it can be screwed as shown in the figure.

To explain its operation, the grindstone (1) is
) to form a predetermined groove B on the opposing surface of the workpiece A.
This is not particularly different from the conventional method, but
To the whetstone (1)! If 11 millimeters occur, 1 the pressing member (
4) to screw it, for example, from the retracted position shown in the third figure to the forward position shown in the fourth figure, and thus the grindstone (
1) is pushed by this and floats up from the 7-lunge (2), and the whole is bent into a waveform as shown in FIG. 5, for example, and the groove has a width corresponding to this.

Note that the first pressing member (4) can also be constituted by a pressing pin that is pushed by an adjusting screw (4&) and advanced toward the grindstone (1), as shown in FIG. 6, for example.

In this way, according to the present invention, when the grinding wheel (1) wears out, it is sufficient to simply move the pressing member (4) forward to apply a corresponding bend to the grinding wheel (1), and the groove can always be kept at a predetermined width. It has the effect of making the work simple and easy.

Claims (1)

[Claims] A disc-shaped grindstone (1) made of a metal disc with cemented carbide abrasive grains bound by electrodeposition or other means is rotated to form a groove in the workpiece with a width corresponding to the thickness of the grindstone (1). In this type, the whetstone (1) is superimposed on the side surface of the rotating seven flange (21) and fixed thereto with a screw (3) or the like, and is located near the outer peripheral edge of the seven flange (2). A grindstone device for groove grinding comprising a suppressing member (4) that presses the side surface of the grindstone (1).
