Description

Knife handles for different types of tools can be installed

This creation is related to the tool of the machine tool, especially a tool holder that can be installed with different types of tools.

The general machine tool uses the relative movement between the tool and the workpiece to complete the cutting work of the workpiece. In the case of a rotary tool (such as a grinding wheel or a drill), the tool is usually mounted on a tool holder, and then the tool holder is mounted on the tool. One of the spindles of the machine, so that the cutter can be rotated together with the cutter by the high-speed rotation of the spindle to achieve the cutting effect.

However, the tool can be used in many different forms because of the processing needs. However, the current design of the tool holder can only be installed with a single type of tool, that is, one tool can only be installed with one tool, so it is necessary to manufacture a variety of different forms. The knives can be matched with the knives. Therefore, the structure of the conventional knives will cause operational troubles and increase in manufacturing costs.

The main purpose of this creation is to provide a tool holder that can be fitted with two different types of tools for the user to select to increase processing efficiency, increase ease of operation, and reduce manufacturing costs.

In order to achieve the above object, the tool holder of the present invention comprises a tool fixing portion and a second tool fixing portion, wherein the first tool fixing portion has a bearing surface and at least two positioning portions disposed on the bearing surface for transmitting One of the bolts in each of the positioning portions Fixing a grinding wheel on the bearing surface, the second tool fixing portion has a central shaft hole for a drill bit to be fixed, whereby the user can select the grinding wheel or the bit pair according to actual needs. A workpiece is processed.

In the embodiment of the present invention, the bearing surface of the first tool fixing portion has a circular shape, and the second tool fixing portion is connected at one end thereof to the bearing surface of the first tool fixing portion and along an axis Extending away from the direction of the first tool fixing portion, the axis passes through the center of the bearing surface, and the central shaft hole of the second tool fixing portion is fixed to the first tool along the axis from the other end of the second tool fixing portion The direction of the department extends. Thereby, the user can selectively install the grinding wheel or the drill bit in the same direction to increase the convenience of operation.

Referring to FIGS. 1 and 2, the tool holder 10 of the present invention includes a first tool fixing portion 11 and a second tool fixing portion 12. The first tool fixing portion 11 has a bearing surface 13 , and the bearing surface 13 can have various geometric shapes, wherein a circular shape is the best choice, and the bearing surface 13 is provided with four positioning portions 14 , which is preferred. Each of the positioning portions 14 of the embodiment is exemplified by a screw hole (actually only at least two The positioning portions 14 are disposed in pairs in a pair with the center of the bearing surface 13 as a center; the second tool fixing portion 12 integrally connects the bearing surface 13 of the first tool fixing portion 11 with one end thereof and Extending along an axis A in a direction away from the first tool fixing portion 11, the axis A will pass through the center of the bearing surface 13. Further, the second tool fixing portion 12 has a central shaft hole 15 and the central shaft hole 15 is from the second The other end of the cutter fixing portion 12 extends in the direction of the first cutter fixing portion 11 along the axis A. On the other hand, the tool holder 10 further has a mounting portion 16 which extends integrally from the side of the first tool fixing portion 11 facing away from the bearing surface 13 along the axis A in a direction away from the first tool fixing portion 11. For mounting the tool holder 10 on a spindle (not shown).

In actual assembly, as shown in FIGS. 3 and 4, the user may choose to apply a grinding wheel 20 to the second tool fixing portion 12 and then abut against the bearing surface 13 of the first tool fixing portion 11. Then, the four bolts 30 are respectively inserted through the through holes 22 of the grinding wheel 20 to be locked in the positioning portion 14 of the first tool fixing portion 11 for fixing the grinding wheel 20 to the first tool fixing portion 11 at this time. The grinding wheel 20 can grind the workpiece as the knife handle 10 rotates. In addition, as shown in FIG. 5, the user can also select a drill bit 30 to be fixed in the central shaft hole 15 of the second tool fixing portion 12, so that the drill bit 30 can drill the workpiece with the rotation of the tool holder 10. operation.

In summary, the knife 10 of this creation can be installed with two different types of rotary cutters, which can not only improve the problem of the conventional knife handle, but also effectively reduce the manufacturing cost. In use, the user can select one of the rotary types according to the processing demand. The tool is mounted, and even the above two rotary cutters (ie, the grinding wheel 20 and the drill bit 40) can be simultaneously fixed to the first and second cutter fixing portions 11 and 12 of the handle 10 (as shown in FIG. 6). To save time in disassembling the tool during machining And to achieve the effect of improving processing efficiency.
