DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

A clamping groove protection cap for a machine tool according to the present invention is capable of preventing a chip generated during a workpiece from being introduced into a clamping groove for assembling and connecting structures of a machine tool, So that the parts can be easily replaced.

Various machine tools such as a lathe machine, a milling machine, and a boring machine are widely used in various industrial fields, and the machine tool is connected and assembled by using the fastening member 30.

As an example of the structure, a vise 1 capable of clamping a workpiece in a lathe machine as shown in Figs. 3 and 4 is characterized in that the jaw 11 and the body 12 are arranged on the upper plate in the forward and backward directions (Hereinafter referred to as "one structure") 11 and a body (hereinafter, referred to as "another structure") 12 by engaging the fastening members 30 at the upper side of the body 12, Is constructed so as to be slidable on the plate.

The one structure 11 includes a rail that moves along the plate guide groove of the vise 1. The other structure 12 mounted and fixed to the upper portion of the structure 11 directly fixes the workpiece .

 A plurality of head grooves 22 and through holes are provided in front of the other structure 12 by the fixing method of the one structure 11 and the other structure 12, The thread groove 21 is formed on the same position line as the thread groove 20 and the fastening member 30 is fastened to the thread groove 21 through the head groove 22 and the through hole to be fixedly coupled.

That is, a head groove 22 and a through hole are formed in the other structure 12 in order to interconnect the respective structures cited as the one structure 11 and the other structure 12, and the other structure 11 And a screw groove 21 to which the screw portion 31 of the fastening member 30 is fitted.

As described above, the coupling groove 20 including the head groove 22, the through-hole and the screw groove 21 is commonly used for interconnecting the respective structures, and when the coupling member 30 is completely engaged The head portion 32 of the fastening member 30 is positioned inside the head groove 22 so as not to be exposed to the outside.

The fastening method of the above-described structure is usually fixed by using the tip end of the threaded portion 31 of the fastening member 30 and the head portion 32 is hidden inside the structure. In the present invention, A hexagonal wrench groove is formed in the portion 32 to tighten or loosen the fastening member 30 by using a socket wrench having the same shape as the wrench groove and the gap between the head groove 22 and the head portion 32 (S) is minimized.

The most significant feature of the present invention is that the protective cap 40 formed with the same diameter as the diameter of the head groove 22 of the other structure 12 is pressed against the head groove 22 to seal the inside of the head groove 22 Thereby preventing external foreign matter from entering into the fastening groove 20 and protecting the fastening member 30.

That is, the protective cap 40 according to the present invention is provided with the shielding surface 41 in the same manner as the shape of the head groove 22, and along the outer peripheral surface of the shielding surface 41 in the longitudinal direction of the head groove 22 The fitting surface 42 of the protective cap 40 is formed integrally with the head portion 32 of the fastening member 30 and the head groove 22 of the fastening groove 20, So that it is forcedly inserted into the gap S to be installed.

In another embodiment, when the head portion 32 of the fastening member 30 is deeply inserted into the head groove 22, the protective cap 40 is inserted into the head groove 22, It is also included in the present invention that the surface 42 is provided so as to be forcedly fitted on the inner surface of the head groove 22. [

3 and 5, the protection cap 40 is formed in a notch shape at the center of the shielding surface 41 and the fitting surface 42 to form a part (such as a bearing or the like) It is possible to quickly remove the protection cap 40 which has closed the engagement groove 20 when the fastening member 30 is to be disassembled for replacement of the fastening member 30.
To this end, in the present invention, the tool 50 such as a screwdriver is positioned in the cutout groove 43 formed at the center of the upper surface of the protective cap 40 as shown in FIG. 5 and then the tool 50 is pressed downward by using a hammer or the like The protective cap 40 is bent in the V-shape by the cutout groove 43 and the fitting portion 42 comes out of the head groove 22 of the coupling groove 20, The head portion 32 of the fastening member 30 located inside the head groove 22 is exposed and the fastening member 30 is fastened to the fastening member 30 by the wrench socket (30) can be separated.
