Description

[0001] The present invention relates to a device for fl ace hole installation,

The present invention relates to a flange hole machining apparatus, and more particularly to a machining apparatus capable of performing hole machining on a flange even in a posture in which hole machining is difficult.

Generally, in order to fix the tubular body to the flange, a hole or the like is machined so that a fastening means such as a bolt can pass. A machine such as a milling machine, a drilling machine, or a machining center is used for machining holes in such workpieces. However, when the flange is formed with a jaw such as a step or the like and the position for machining the hole is inside the jaw, there is a problem that the machining of the hole is difficult because the head driving shaft of the machine and the central axis of the tool are positioned on a straight line.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a flange hole machining apparatus capable of drilling holes in a single process while shortening the above-mentioned problems, thereby shortening the number of working holes.

In order to achieve the above object, according to the present invention, there is provided an apparatus for machining a hole of a flange that connects a tube body having opposite ends disposed opposite to each other, comprising: a chucking member for chucking the hollow portion of the flange, ; An ELM guide mounted on a front surface of the body so as to be slidable in a vertical direction, and a hole formed in a front surface of the ELM guide to process a hole in the flange, And a drilling member including a drill.

As described above, according to the present invention, the following effects can be expected.

Hole machining can be easily performed, and adjustment of the height of the tool can be effected by replacing or adjusting the length in consideration of the hole machining position and the position of the jaw.

1 is a view showing a preferred embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail.

The present invention relates to an apparatus for machining a hole of a flange connecting ends of tubular members disposed opposite to each other, the basic structure of which comprises a chucking member for chucking a hollow portion of the flange, An ELM guide mounted on the front surface of the body so as to be slidable in a vertical direction; and a flange provided on the front surface of the ELM guide so as to be movable forward and backward, And a drilling member including a drill for machining the hole.

Embodiments that can be derived from the basic structure of the present invention will be described in detail as follows.

1, a preferred embodiment of the present invention includes a housing 110, a driving member 120, a driven member 130, a power transmitting member 140, a tool fixing member 150, 160).

The housing 110 is fastened to the upper and lower sides by bolts and is fastened with bolts or the like so that the lower ends of the driving member 120 and the driven member 130 can be inserted and supported therein. Respectively. Further, at both ends of the upper surface of the lower housing of the housing 110, a circular groove concentric with the both end holes of the upper housing is formed. At this time, bearings are inserted and fixed into the circular groove of the lower housing to smooth the rotation of the driving member 120 and the driven member 130, and the driving member 120 and the driven member 130 So that the bottom surface is brought into contact.

The driving member 120 is formed in a cylindrical shape having a stepped shape so as to be mounted on one end of the housing 110 so as to be connected to and driven by a connection chuck of a hole processing machine such as a drilling machine or a machining center.

The driven member 130 is formed in a stepped shape with a cylindrical shape so as to be vertically provided on the other end of the housing 110 while being spaced apart from the driving member 120 in a horizontal direction. At least one of the follower member 130 or a tool fixing member 150 to be described later may be formed by chucking or unchucking the tool fixing member 150 or the tool T It is preferable that it is provided in a chuck form. In addition, the driven member 130 is provided with a key groove connected to the key groove of the tool fixing member 150 on the outer circumferential surface thereof, and a key is inserted into the corresponding key groove so that the driven member 130 and the tool fixing member 150).

The power transmitting member 140 is connected to the driving member 120 and the driven member 130 to transmit the power of the driving member connected to the coupling chuck of the hole processing machine to the driven member 130. [ However, the present invention is not limited thereto. For example, a timing belt or the like may be connected thereto.

It is preferable that the driving member 120 and the driven member 130 are formed on the outer circumferential surface of the driving force transmitting member 140 so as to be meshed with the inner circumferential surface of the timing belt when the power transmitting member 140 is a timing belt.

The tool fixing member 150 is provided in a chuck form when the driven member 130 is not provided in the form of a chuck and is fixed or separated to the lower end of the driven member 130, And can be changed according to the diameter of the tool T or the fixed length of the tool T. When the driven member 130 is not provided in the form of a chuck, the tool fixing member 150 is formed with a spiral in the upper peripheral surface and a helical hole is formed in the inner peripheral surface of the driven member 130 so that the spiral can be fastened. (Not shown in the drawing) which is formed by screwing on the upper spiral is forcedly attached to the bottom surface of the follower member 130 to prevent the fastening force from being released when fastened to the spiral hole of the follower member 130.

That is, the tool fixing member 150 has a center hole through which the tool T is inserted, a fastener 152 divided into six pieces through grooves to tighten the tool T at the lower end of the center hole, And a fastening cover 154 for fastening and unfastening the fastener 152.

A spiral is formed on the lower end outer circumferential surface of the fastener 152 and a spiral is formed on the inner circumferential surface of the fastener cover 154 to rotate the fastener cover 154 so that the lower end inclined surface of the fastener cover 154 is engaged with the fastener 152 The tool T is fixed by tightening the fastener 152 gradually while closely contacting the lower end slope. Conversely, when the fastening cover 154 is rotated in the opposite direction, the lower end inclined surface of the fastening cover 154 is separated from the lower end inclined surface of the fastener 152, and the fastener 152 is released to separate the tool T.

The rotation preventing member 160 is supported at one end of the housing 110 by a head of the hole processing machine to prevent the housing 110 from interlocking with the driving member 120 when the driving member 120 is driven. For example, a frame extending upward is fixed to one end of the housing 110, and a fixing frame is connected to an upper end of the frame so as to be fitted and fixed to the head of the hole processing machine.

Therefore, the operation of the machine-mounting hole and tapping jig 100 according to the present invention is as follows, as shown in FIGS.

First, a hole is formed by machining at a hole machining position where a jaw is formed by the flange of the workpiece and is blocked by the jaw, and the upper end of the drive member 120 is machined by a hole machining machine such as a drilling machine or a machining center The connecting chuck of the head is rotated and the driven member 130 is interlocked by the power transmitting member 140 connected to the driving member 120. When the driven member 130 is coupled to the connecting chuck, The tool T is rotated while the tool fixing member 150 mounted on the tool T is rotated. Since the center axis of the connecting chuck of the machine head and the center axis of the tool T are not aligned with each other, machining such as a hole can be performed even at a portion covered by the jaw regardless of the jaw of the workpiece.

At this time, when the workpiece has different machining dimensions such as a hole to be machined, the tool holding member 150 to which the tool T or the specific tool T is fixed is used in replacement.
