Abstract

PURPOSE: To provide a grinding device capable of performing a stable dressing by properly bringing a grinding wheel and a dressing cutter into contact with each other and secularly maintaining the grinding quality of the grinding wheel. CONSTITUTION: A grinding device 1 is provided with a device body 1A rotatably supporting a rotary shaft 3 to which a grinding wheel 2 is fixed, a fixing cover 4 which is fixed to the device body 1A and covers the outside of the grinding wheel 2 and a movable cover 5 openable/closable for the fixing cover 4. The fixing cover 4 is provided with a diamond dressing cutter 6 capable of advancing/retreating in a normal direction of a circumferential part of the grinding wheel 2 fixed to the rotary shaft 3 by being extended within the fixing cover 4. In the dressing cutter 6, advancing/retreating amount is adjusted by manually rotating an adjusting screw 7. At a tip of the dressing cutter 6, a diamond cutter 6a of a small lump is mounted. Therefore, a contact degree of the diamond cutter 6a of the dressing cutter 6 and the circumferential surface of the grinding wheel 2 is determined by the adjustment of the adjusting screw 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grinding machine provided with a rotary shaft for rotating a grinding wheel, for example, and more specifically, can grind the grinding wheel, and moreover, perform this dressing operation stably. The present invention relates to a grinding device having a configuration capable of performing.

[0002]

2. Description of the Related Art Conventionally, relatively sharpening of the grindstone surface of a grinding wheel has been performed by directly pressing a flat, block-shaped diamond dressing cutter against the circumferential surface of a rotating grinding wheel.

[0003]

However, in such conventional dressing work, since the flat dressing cutter is directly pressed against the circumferential surface of the grinding wheel, the degree of contact is unstable. However, if the degree of contact is small, the sharpening will be insufficient, while if the degree of contact is large, the circumferential surface of the grinding wheel will be abraded and the sharpness tends to be lost. It was

The present invention has been made in view of the above circumstances, and maintains the grinding quality of the grinding wheel with time, in addition to bringing the grinding wheel and the setting cutter into proper contact with each other for stable setting. It is an object of the present invention to provide a grinding device that can be used.

[0005]

In order to achieve the above object, the present invention provides an apparatus main body that rotatably supports a rotary shaft to which a grinding wheel is fixed, and an external body of the apparatus that is fixed to the apparatus main body. A grinding device having a fixed lid for covering the other side and a movable lid that can be opened and closed with respect to the fixed lid, wherein the fixed lid is provided with a groove relative to the circumferential portion of the grinding wheel fixed to the rotary shaft. A sharpening cutter made of diamond that can move back and forth in the line direction,
An adjusting mechanism for adjusting the amount of advance / retreat of the dressing cutter is provided.

Further, the present invention is characterized in that the movable lid is provided with a see-through window through which the contact position between the grinding wheel and the tip of the dressing cutter can be visually confirmed.

[0007]

By operating the adjusting mechanism, it is possible to adjust the amount of advance and retreat of the dressing cutter in the normal direction to the circumferential portion of the grinding wheel. Since the dressing cutter is supported by the fixed lid, the amount of advance and retreat is stable. Therefore, it is possible to repair the cutouts, irregularities or various defects of the grinding wheel with stable sharpening.

The adjusting mechanism adjusts the degree of contact between the grinding wheel and the dressing cutter by providing the movable lid with a transparent window through which the contact position between the grinding wheel and the tip of the dressing cutter can be visually checked. It can be done while doing so, and more stable dressing can be performed. That is, the dressing cutter does not apply unnecessary force to the grinding wheel, prevents excessive wear of the grinding wheel, and does not affect the grinding quality of the grinding wheel over time.

[0009]

Embodiments of the present invention will now be described with reference to the drawings. 1 and 2 show an embodiment of the present invention. A grinding apparatus 1 shown in FIG. 1 includes a device body 1A that rotatably supports a rotating shaft 3 to which a grinding wheel 2 is fixed, and a device body 1A that is fixed to the device body 1A. A fixed lid 4 that covers the outside of the grinding wheel 2 and a movable lid 5 that can be opened and closed with respect to the fixed lid 4 are provided. In addition, the fixed lid 4 has a grinding wheel 2 fixed to the rotary shaft 3.
A diamond-made dressing cutter 6 capable of advancing and retreating in the normal direction with respect to the circumferential portion of is provided in the fixed lid 4 by extending, and the dressing cutter 6 rotates an adjusting screw (adjusting mechanism) 7 manually. Therefore, the amount of advance / retreat is adjusted. A small-sized diamond cutter 6a is attached to the tip of the dressing cutter 6. Therefore, the degree of contact between the diamond cutter 6a of the dressing cutter and the circumferential surface of the grinding wheel 2 is determined by adjusting the adjusting screw 7.

The movable lid 5 has a see-through window 8 through which the contact position between the grinding wheel 2 and the diamond cutter 6a can be visually observed.
Are formed. In this embodiment, a transparent body such as transparent glass is adhered to the see-through window 8 with an adhesive or the like,
Protects eyes from grinding debris. Further, the see-through window 8 is an elongated hole corresponding to the normal direction of the grinding wheel 2.

Next, the operation will be described. In the above configuration,
When setting the grinding wheel 2, the adjusting screw 7 is rotated to bring the diamond cutter 6a of the setting cutter 6 into contact with the circumferential surface of the grinding wheel 2 and rotate the grinding wheel 2. By adjusting the degree of contact between the grinding wheel 2 and the cutter 6a with the naked eye through the transparent window 8 formed in the movable lid 5 with the adjusting screw 7, the sharpening does not become insufficient, and the cutter 6a is used. Grinding wheel 2 without giving unnecessary force to grinding wheel 2
Alternatively, it is possible to prevent excessive wear of the cutter 6a, and thereby improve the grinding quality of the grinding wheel 2 over time.

The shape of the see-through window is not particularly limited. Further, by providing a lens on the transparent window 4, the degree of contact between the grinding wheel 2 and the cutter 6a can be more accurately viewed.

[0013]

As described in detail above, in the grinding wheel dressing device of the present invention, when the diamond dressing cutter sets up the grinding wheel, the adjusting mechanism provided on the fixed lid makes contact with the circumferential surface of the grinding wheel. It is possible to easily move forward and backward to determine the degree, and more stable setting can be performed by visually adjusting the degree of contact of the setting cutter with the naked eye through the transparent window, and the grinding quality of the grinding wheel over time. Can be increased.
