Description

Grinding wheel diamond dressing structure with reusable shank and switchable edge angle

The present invention relates to a diamond dressing structure for dressing a grinding wheel mounted on a grinding machine.

Press, generally the grinding wheel installed on the grinding machine will cause the surface of the grinding wheel to be uneven after use, or make its shape deviate from the true circle. The new grinding wheel also needs to be edged before it can be used normally. "Leveling", "sharpening" of a true circle, or "edging" of a new grinding wheel are usually done with a diamond dressing.

A conventional diamond dressing tool (80), as shown in Fig. 11, mainly has a round rod-shaped metal handle (81), and one end of the handle (81) is cut or ground to form a sharp cone portion (82), a diamond (83) is embedded in the tip of the tapered portion (82), and the above-mentioned "leveling" can be successfully completed by using the diamond (83) to make contact with the rotating grinding wheel , "sharpening" or "blade" and other actions, and the handle (81) needs to have a certain length, so that the diamond dressing (80) can be fully penetrated through the handle (81) when in use. Hold on.

However, the above-mentioned conventional structure still has the following problems in practical application: (1) The diamond dressing (80) is blunted when the diamond (83) is blunted, or is caused by the force during cutting; After the diamond (83) is dropped, the entire knife handle (81) needs to be discarded. However, because the length of the knife handle (81) is not too short, the direct discarding will not only cause waste, but also cause waste. A heavier burden on the cost of use; (2) The diamond trimmer (80) is in contact with the grinding wheel at the most protruding point (edge) of the diamond (83). When the most protruding edge is blunt, it will cause The trimming precision is reduced, so the conventional method will list the diamond trimmer (80) as a one-time consumable, which is quite uneconomical to use.

Therefore, the inventor of the present invention has considered the idea of creation in view of this, and has designed it with years of experience. After many discussions and sample tests, and many revisions and improvements, the present invention is launched.

In the conventional diamond dressing knife, after the diamond is blunted or the diamond is dropped due to the force of cutting, the entire knife handle needs to be discarded, which is the technical problem to be solved.

The present invention also has a grinding wheel diamond dressing structure with reusable tool handle and switchable cutting edge angle, which comprises: a round rod-shaped metal handle, a fixing piece and at least one replaceable cutter head, wherein, A slot is recessed in the center of one end of the handle. The slot has a reference surface and five abutting surfaces. Through the continuous connection and surrounding of the reference surface and the abutting surfaces, the hexagonal slot can be formed. , and the outer peripheral side of the tool handle is provided with a fixing hole that penetrates into the slot, so that the fixing hole can be used to provide the fixing piece for installation. The replacement tool head has a body, and the body is hexagonal. so that the main body can have six consecutive positioning surfaces, and one end of the main body is provided with a sharp cone part, and the tip of the sharp cone part is embedded with a diamond, and the main body is used to insert the knife handle. After the sharp cone and the diamond are exposed to the shank, the fixing member is used to make the positioning surface By tightening the limit, the combination of the handle and the replacement head can be completed, so that the diamond trimmer can use the cutting edge formed by the most protruding point on the diamond to level the grinding wheel, By sharpening or cutting the edge, the reference plane and the abutting surface simultaneously provide each positioning surface of the replaceable cutter head for abutment, which can greatly improve the combination stability of the tool holder and the replaceable cutter head, so as to improve the stability of the combination. In addition to avoiding the rotation of the replaceable cutter head due to the force during use, it is also possible to use the replaceable cutter head to rotate after being removed and re-insert the insert when the cutting edge of the diamond is blunt. The groove is used to convert the angle of the cutting edge, so that the replaceable cutter head can be re-finished with high precision without immediate replacement, and the conversion of the cutting edge angle is based on the reference surface and the The different positioning surfaces are supported by the support; thereby, the structure of the grinding wheel diamond dressing with the reusable tool shank and the changeable edge angle can be formed.

(1) The grinding wheel diamond dressing structure of the present invention, which has both the reusable shank recyclable use and the switchable cutting edge angle, when the diamond is blunt or dropped, only the replacement cutter head needs to be replaced, The longer and more expensive handle can be used all the time, so as to avoid waste caused by discarding the handle, and the diamond trimmer can also have the advantage of low cost of use.

(2) The grinding wheel diamond trimming structure of the present invention has both the reusable handle of the tool and the changeable cutting edge angle. When the cutting edge of the diamond is blunt, there is no need to rush to make the replacement cutter head For replacement, the replacement cutter head is removed and rotated, and reinserted into the slot to change the angle of the cutting edge, so that the replacement cutter head can be replaced again without immediate replacement. The ability to obtain high-precision dressing, and because the interchangeable head has six locating surfaces to convert, allows the The replacement cutter head is no longer a one-time consumable, but can be used at least six times, which will be more economical in use.

(3) The diamond dressing structure of the present invention has both the reusable handle of the tool and the changeable cutting edge angle. During the dressing process, if the diamond is blunted or dropped, abnormal vibration or abnormal sound will occur. At the time, the operator can be notified through the sensing of the sensing device, so that the operator can know the current status of the diamond trimmer, and then take the most appropriate treatment, so as to prevent the diamond trimmer from reaching its service life. If the upper limit is reached, it is wasteful to simply replace it, or the diamond dressing tool has long been unusable and has not been replaced, which affects the dressing accuracy.

(4) In the present invention, the grinding wheel diamond trimming structure with reusable tool handle and switchable cutting edge angle, the sensing device is completely embedded in the handle, and can be sensed wirelessly Therefore, it will not have any undue influence on the use of the diamond trimmer, and the installation process of the sensing device will be relatively simple, fast and convenient because no additional wiring is required. .
