Description

Grinding machine tool edge angle inspection structure

This creation is about a "tool edge angle inspection structure of a grinder", especially a inspection structure that can be used to clamp a tool such as a drill bit, a milling cutter, and the like to facilitate inspection of the cutting edge angle.

According to the prior art, when the user wants to use a tool grinder to grind a tool such as a milling cutter or a drill, the tool must be clamped and fixed by a tool holder. The existing tool holder mainly has a front collet nut, and the front The collet nut is internally provided with a tapered hole, and an inner thread is arranged on the inner wall of the tapered hole, and the outer peripheral side of the front collet nut is flattened to form a plurality of positioning surfaces, and the cone is further formed. The inside of the shaped hole is provided with a collet, which is composed of a plurality of elastic sheets, and a central portion of the collet is provided with a clamping hole corresponding to the tapered hole, and further comprises a rear collet The outer peripheral side of the cap is provided with an external thread for screwing with the internal thread, so that the front collet nut and the rear collet nut can be screwed and fixed, and the center position of the rear collet nut Wherein, the tapered hole is provided with a perforation, whereby the user only needs to pass a cutter into the clamping hole, then place the collet in the tapered hole, and let the front collet nut And the rear collet nut is screwed and fixed, so as to be pushed through the rear collet nut toward the collet Moving direction of the front of the collet nut, the tapered bore to produce by wedge action, to press the collet to contract inward, to achieve the purpose of clamping of the tool.

After the clamping and fixing work of the tool is completed, the positioning device can be further inserted. Positioning the tool, the existing positioning device has a base, and the base is provided with a fixing hole, and a fixing block is arranged adjacent to the fixing hole, and an adjusting block is slid on the other base, and the adjusting block is attached. The adjusting hole is provided with an adjusting portion, and the adjusting block is provided with an adjusting bolt for moving the adjusting block on the base, thereby placing the tool holder in the fixing hole and stopping the positioning surface on the fixing block, so that the positioning surface is blocked The front collet nut does not have the freedom of rotation, and then the front and rear collet nuts are loosened slightly, and then the cutter tail is rotated to align the cutting edge of the cutter with the positioning surface of the front collet nut. Then, the front collet nut and the rear collet nut are locked and fixed, so that the positioning of the tool can be completed.

Although the above tool holder can effectively clamp the tool for further positioning through the positioning device, when the tool length is smaller than the tool holder, that is, when the tool tail is hidden in the tool holder, the user will not be able to touch the tool. The tool cannot be rotated smoothly to complete the positioning, which requires an additional extension rod to further complete the positioning of the short knife.

In response to these problems, a manufacturer has created a tool holder for the short knife of the bulletin No. M477343, which includes a front collet nut and a rear collet nut that can be screwed to each other, and is clamped thereto. a collet between the front collet nut and the rear collet nut, wherein the outer collet nut outer sleeve is provided with a positioning ring, and the positioning ring is provided with a positioning hole, the positioning hole is The snail is provided with a positioning member, so that when the clamping squeegee is positioned, the positioning member can be loosened first, so that the front collet nut can be rotated relative to the positioning ring, and then locked after the short knives are positioned. The positioning member fixes the relative position of the positioning ring and the front collet nut, so that the extension bar is not used for the short knife clamping positioning.

However, in the case of the prior case, the positioning of the positioning member is first performed by using a tool to loosen the positioning member, so that the front collet nut can be rotated relative to the positioning ring, and the operation mode is troublesome. Moreover, it is not convenient to find a suitable tool for operation. Moreover, the prior case is a combination of radial pressing and locking, which is easy to cause damage to the constituent components and reduce the overall service life.

Moreover, the conventional structure does not ensure that the position of the tool edge is in the correct position after the positioning of the tool by the positioning device, and there is still inaccuracy through the visual method of the operator; and for such problems, There is a need to further improve it.

In view of the fact that there are still improvements in the current structure, the creator has been engaged in the multi-year production and sales experience of related products, and has focused on improving the existing problems. After many improvements, he finally created a kind of grinding. Machine tool edge angle inspection structure.
