Description

Tapping jig {JIG FOR TAPPING}

An embodiment of the present invention relates to a jig for tapping.

Generally, in the process of assembling components of a machine or an industrial device, they are assembled by using bolts and nuts. For this purpose, a process of forming a screw hole in the metal is required. The general process of forming a screw hole in a metal is as follows.

A hole having a size slightly smaller than the outer diameter of the bolt to be inserted into the screw hole is drilled to drill the hole and a tab having an appropriate dimension corresponding to the hole is inserted into the hole so that the lubricant or cutting oil is supplied at a low speed, The threads of the tabs form a thread to which the bolt and the screw are coupled in accordance with the dimensions and shape.

However, in order to perform tapping for forming threads, it is necessary to manually tap the metal to be screwed into the tapping device to perform tapping, so that it is difficult to carry out elaborate work, the efficiency is low, There is a disadvantage that it is manufactured inconsistently.

Further, since the tabs are threaded without a separate jig, it is difficult to perform tapping while aligning the center line of the hole in the workpiece with the center line of the tab, and therefore, the work is required to be proficient, There is a problem that the tab breaks easily when it does not.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, this is merely an example and the present invention is not limited thereto.

In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intention or custom of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

The technical idea of the present invention is determined by the claims, and the following embodiments are merely a means for effectively explaining the technical idea of the present invention to a person having ordinary skill in the art to which the present invention belongs.

1 is a view illustrating a jig for tapping according to an embodiment of the present invention.

FIG. 1A is a view showing a jig 10 according to an embodiment of the present invention, and FIG. 1B is a view showing that an elastic member 30 is disposed inside a jig 10. FIG.

Referring to FIG. 1A, a jig 10 according to an embodiment of the present invention may include a top jig 110 and a bottom jig 120.

The upper jig 110 and the lower jig 120 are formed in a 'C' shape and may include a space therein. The upper jig 110 and the lower jig 120 may be fastened to each other and include a space through which tabs 42 (see FIG. 2) can pass. However, the upper jig 110 and the lower jig 120 are not limited to a "C" shape, and may include a shape including a space through which the tab 42 can pass while supporting the tab.

The upper jig 110 includes a first hole 111 into which a tab can be inserted and a lower jig 120 has a second hole 121 in which the tab 42 inserted in the upper jig 110 can be protruded ). The tab 42 can penetrate the first hole 111 and enter the second hole 121. [ Accordingly, the tabs 42 may form tabs on the object S disposed under the lower jig 120 through the second holes 121. [0053]

The first hole 111 and the second hole 121 may be vertical with respect to the ground. Accordingly, the tab 42 passing through the first hole 111 can pass through the second hole 121 in the vertical direction, and tap the object S. The tabs 42 that have passed through the first holes 111 and the second holes 121 that are vertical can be vertically tapped to the object S because they pass vertically.

Referring to FIG. 1B, the jig for tapping according to an embodiment of the present invention may include a height adjusting portion 20 and an elastic member 30.

The height adjusting unit 20 can adjust the height of the upper jig 110 in the vertical direction by fastening the upper jig 110 and the lower jig 120 together. The height adjusting unit 20 may include a fastening member for fastening the upper jig 110 and the lower jig 120 together. The upper jig 110 and the lower jig 120 may be formed with through holes (not shown) through which the height adjuster 20 can pass so that the upper and lower jigs 110 and 120 can be fastened to each other by the height adjuster 20. The height adjusting unit 20 may be coupled to the upper jig 110 through the lower jig 120.

The height adjusting portion 20 is moved up and down along the height adjusting hole 122 (see FIG. 3) formed in the lower jig 120 so that the upper jig 110 fastened to the height adjusting portion 20 can also be moved up and down have.

The elastic member 30 can be disposed in the space inside the jig 10. [ The elastic member 30 may be formed so as not to interfere with the diameters of the first hole 111 and the second hole 121. For example, the elastic member 30 may be formed by a spring, and the space inside the spring that is continuously wound may be formed to be larger than the diameter of the first hole 111 and the second hole 121. Therefore, a space through which the tab 42 can pass from the first hole 111 to the second hole 121 can be formed in the elastic member 30.

2 is a view illustrating a jig for tapping according to an embodiment of the present invention.

FIG. 2A is a view illustrating a tapping jig in a state where a tab 42 is inserted according to an embodiment of the present invention. FIG. 2B is a side view of a jig for tapping in a state where a tab 42 according to an embodiment of the present invention is inserted, Fig. 7 is a view showing a jig for tapping.

Referring to FIGS. 2A and 2B, the tab 42 includes a tab handle 41 at an upper portion thereof. When the tab 42 of the tab 42 is inserted into the first hole 111 of the jig 10 and the tab handle 41 of the tab 42 contacts the upper jig 110, ) Insertion can be stopped.

For example, when the length of the tab 42 is longer than the length of the jig 10 in the longitudinal direction from the upper portion to the lower portion, the tab handle 41 is fixed in contact with the upper outer surface of the upper jig 110 The tabs 42 may pass through the second holes 121 and may be tapped to the object S. [

If the length of the tab 42 is shorter than the length in the longitudinal direction from the top to the bottom of the jig 10, the tab 42 can not be tapped on the object S with the tab 42 inserted into the jig 10 So that the height of the jig 10 in the longitudinal direction can be adjusted through the height adjusting portion 20.

When the height regulating portion 20 is lowered, the upper jig 110 can be lowered downward. Therefore, the entire length of the jig 10 is shortened, so that it is possible to tap the object S by adjusting the height of the jig 10 in accordance with the length of the tab 42. [

3 is a view illustrating a jig for tapping according to an embodiment of the present invention.

Referring to FIG. 3, the lower jig 120 may include a height adjusting hole 122 in which the height adjusting portion 20 can be moved up and down.

At least one height adjusting hole 122 may be formed in the lower jig 120. For example, height adjustment holes 122 may be formed on both sides from the upper side to the lower side so as to face each other. The height of the upper jig 110 can be adjusted more stably when the height adjusting holes 122 are formed on both sides so as to face each other.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, . Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by equivalents to the appended claims, as well as the appended claims.
