Description

TOOL HOLDER {TOOL HOLDER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool holder, and more particularly, to a tool holder that fixes a tool so that one holder can be used for outer diameter machining and end cutting.

In general, machine tools such as Numerically Controlled Lathe (CNC) and Computerized Numerically Controlled Lathe (CNC) require various tools for machining a workpiece. During machining, the necessary tools are attached to the tool rest, and the workpiece is machined while rotating the tool on the machine tool.

At this time, the tool is divided into an outer diameter machining tool, an inner diameter machining tool, and a section machining tool according to the machining area of the workpiece, and each tool holder is required to mount these tools on the workbench.

The tool holder mounted on the tool stand consists of an outer diameter holder, an inner diameter holder, and a one-sided holder. Here, the three types of tool holders are determined in accordance with the division angle (octagon, tenth, twelve, etc.) of the tool rest.

Recently, the shape of the workpiece has become complicated, the number of tool holders attached to the tool holder has increased, and since more tools are required than the number of tool holders that can be attached to the tool holder, . Further, when a user purchases a machine tool and then purchases a holder for an outer diameter machining, a holder for an inner diameter machining, and the like, the respective tool holders must be purchased separately. Therefore, there is a need for improvement.

Background Art [0002] The background art of the present invention is disclosed in Korean Patent Laid-Open Publication No. 10-2014-0011759 (published on Apr. 29, 2014, entitled Adapter Interchangeable Tool Holder).

SUMMARY OF THE INVENTION An object of the present invention is to provide a tool holder for fixing a tool so that a workpiece can be machined and sectioned by a single holder.

In the present invention, the lower holder includes: a lower holder body; A lower holder inclined portion formed on an upper surface of the lower holder body and formed to be inclined downward forward; And a guide projection protruding from the lower holder inclined portion.

In the present invention, the lower holder inclined portion is formed with a lower holder fastening hole which is fastened by the upper holder and the first fastening member.

In the present invention, the upper holder includes: an upper holder inclined portion which faces the lower holder inclined portion and is inclined downward toward the front; An upper holder flat portion formed on an upper portion of the upper holder inclined portion and having an upper holder first fastening hole communicating with the lower holder fastening hole; And an upper holder tool receiving portion formed to be orthogonal to the upper holder plane portion and having an upper holder second fastening hole communicating with the lower holder fastening hole as the upper holder slanting portion is changed in a direction of contact with the lower holder slanting portion, .

In the present invention, the upper holder inclined portion further includes a guide groove portion corresponding to the guide protrusion.

In the present invention, the upper holder tool receiving portion is formed with a tool receiving groove for receiving the tool.

In the present invention, the lower holder fastening hole is selectively in communication with the upper holder first fastening hole or the upper holder second fastening hole according to a direction in which the upper holder inclined portion contacts the lower holder inclined portion.

In the present invention, the first fastening member fastens the lower holder fastener and the upper holder first fastener or the lower holder fastener and the upper holder second fastener to couple the lower holder and the upper holder.

According to the tool holder of the present invention, the upper holder on which the tool is mounted can be separated from the lower holder and rotated to perform the outer diameter machining and the end surface machining on the workpiece.

The upper holder tool receiving portion 32 is formed to be orthogonal to the upper holder flat surface portion 31 and an upper holder second fastening hole 37b communicating with the lower holder fastening hole 27 is formed. The upper holder second fastening hole 37b is in communication with the lower holder fastening hole 27 as the direction in which the upper holder slanting portion 33 contacts the lower holder slanting portion 23 is changed. The upper holder second fastening hole 37b is formed to correspond to the size and number of the lower holder fastening hole 27.

In the upper holder tool receiving portion 32, a tool receiving groove 39 for receiving the tool 10 is formed. The tool 10 is accommodated in the tool receiving groove 39 and then fastened to the upper holder tool receiving portion 32 by the second fastening member 50. A plurality of through holes 11 through which the second fastening member 50 can pass are formed on one side (reference right side in FIG. 3) of the tool 10. The through hole 11 is formed to have a size corresponding to the head portion of the second fastening member 50 so that the head portion of the second fastening member 50 is not exposed to the outside, . The second fastening member 50 is made of fastening means such as a bolt or a screw.

The upper holder first fastening hole 37a and the upper holder second fastening hole 37b can be selectively inserted into the lower holder fastening hole 33a as the direction in which the upper holder slanting portion 33 contacts the lower holder slanting portion 23 is changed, 27). The upper holder first fastening hole 37a or the upper holder second fastening hole 37b communicated with the lower holder fastening hole 27 is fastened by the first fastening member 40 so that the upper holder 30 is fastened to the lower holder 30, (Not shown).

The upper holder (30) according to the present invention further includes a guide groove (35). The guide groove 35 is formed in the upper holder inclined portion 33 of the upper holder 30 so as to correspond to the guide protrusion 25 formed in the lower holder inclined portion 23 of the lower holder 20. The guide groove 35 and the guide protrusion 25 may be coupled to each other so that the upper holder 30 is coupled to the lower holder 20. Therefore, the operator can easily connect the upper holder 30 to the lower holder 20, and the upper holder 30 is not separated from the position where the upper holder 30 is coupled to the lower holder 20.

Hereinafter, the operation of the tool holder according to the present invention will be described.
