Description

[0001] The present invention relates to a vise extension apparatus for a milling machine,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vise extender for a milling machine that places a workpiece on the top surface of a mill of a milling machine and fixes the workpiece to a fixture or the like during work to perform precision work.

There are two main methods for cutting metal using a cutting tool. First, cutting is performed by contacting a notched portion of a cutting tool fixed to a rotating metal workpiece,

Secondly, a tool having a cutting edge, that is, a cutting insert is fixed to a machine tool by using a tool holder, and then the cutting tool is rotated under such a condition and brought into contact with a previously fixed workpiece, .

The milling process belongs to the second method among the above cutting methods. The milling cutter is used to perform a planing process, a side process, a right-angle process, a groove process, and a hole process.

When the initial workpiece is formed by casting, the parts to be used for the cutting tool, the various machines, and the precision parts used for the automobile engine are finished by machining the outer surface of the formed workpiece with a machine tool such as a milling machine.

These precision parts are often machined to very fine dimensions and often do not work well with small errors. Therefore, the precision part workpiece is fixed by using a fixture (called "jig, vise, clamping" or the like) in order to precisely carry out work such as cutting by a milling machine.

Normally, a workpiece is placed on the top surface of a milling machine. However, when detailed work such as manufacturing a small-sized or radial-shaped groove such as a precision part is required, the fixture is first fixed to the upper surface of the bed, To the fixture or the like.

In recent years, due to the development of industrial technology, workpieces having complex shapes have been increasing, and the above-mentioned fasteners (vise, jig, clamping, etc.) are being developed in various ways.

For example, in Korean Patent Laid-Open Publication No. 1020130008260 (Feb. 31, 2013), there are provided a main body, a fixing jaw provided at both sides of the main body, a supporting base, and a fixing base provided at the end of the screw shaft penetrated through the base, A vise for a milling machine comprising a horizontal moving jaw, wherein an adjusting dial through which a fastening bolt formed at an end of the fastening groove is pivoted is provided on the outer side of the fastening jaw, Wherein a locking pawl which is inserted into the locking pawl is installed on the outer side surface of the locking pawl and is screwed to the locking bolt through a tightening bolt hole formed to be penetrated to thereby integrally rotate with the adjusting dial, An angle scale indicating the rotation angle of the first rotation jaw is displayed based on the reference, and on the inner side of the movement jaw, A vise for a milling machine capable of adjusting the angle is disclosed,

In Korean Patent Registration No. 1013095850000 (2013.09.11), there is provided a table having upper and lower tie-bolt insertion grooves spaced along the longitudinal direction on the upper side of the base plate, and the table is provided on both sides of the base plate And a table angle adjusting unit for adjusting a table angle of the table by a handle operation between the pair of table supporting units, Wherein the table supporting portion includes a table fixing portion for maintaining an angle adjusted by the table angle adjusting portion,

In Korean Patent Registration No. 2004457880000 (Aug. 24, 2009), there are disclosed a fixed table mounted on a bed of a milling machine, a fixed table mounted on a bed of a milling machine for vertically rotating the first indexing plate, A first indexing device mounted at one end, a turning table having one end mounted on the first indexing plate and the other end rotatably mounted on the other end of the fixed table, a second indexing A first indexing device mounted on the upper part of the revolving table so that the plate can rotate horizontally, a first backlash preventing device mounted on the fixing table so as to face the first indexing device so as to prevent backlash of the first indexing device, And a second backlash mounted on the turning table to prevent backlash of the second indexing device, And a fixture for fixing the index stage, the workpiece to be machined is fixed to the bed of a milling machine, consisting of the public,

In the domestic utility model registration publication No. 2002281440000 (Apr. 10, 2001), a plurality of fixing holes 12 are formed on both sides of the upper surface of the plate-shaped base 4, A fixing table 6 and a presser bar 8 are provided on a guide 10 on the upper surface of the base 4 so that the presser bar 8 presses the workpiece by the operation of the screw 20 It can be seen that the workpiece fixing vice is disclosed.

1. Korean Patent Laid-Open Publication No. 1020130008260 (Feb. 2. Registered Patent Registration No. 1013095850000 (2013.09.11) 3. Registered Patent Registration No. 2004457880000 (Aug. 24, 2009) 4. Domestic Utility Model Registration Bulletin Registration No. 2002281440000 (2001.04.10)

Conventional vices have been developed to be used in accordance with one product, and therefore, there has been a problem in that products of various sizes can not be fixed to the vice. More specifically,

It is difficult to fix a workpiece that is out of the maximum size of the vise to a vise, so that a vise of various sizes must be provided. However,

It is an object of the present invention to solve the problem that the processing time is prolonged due to the problem of setting time for searching for a vise suitable for the size of the workpiece or moving to another workshop,
