Abstract

The present invention provides a two-head milling apparatus having an ascending/descending lower clamp body. A lower clamp body for supporting the lower end of a workpiece is provided on a lower side of a two-head milling apparatus in which the workpiece is inserted into a fixed table body and a moving table body and both sides of the workpiece are simultaneously milled by a first cutting body and a second cutting body. The lower clamp body is lifted to firmly support the workpiece to prevent the workpiece from shaking or moving during machining. The lower clamp body can be firmly supported by the lower clamp body even if the machining width of the workpiece is narrow. If the machining width of the workpiece is minimum, the lower clamp body is lowered to prevent the movement of the second cutting body from interfering with the first cutting body to allow minimum-width machining on the workpiece.

Description

Processing apparatus for two heads milling with up and down type supporting clamp}

The present invention relates to a double-headed milling device having an elevating lower clamp body, and more particularly, by raising or lowering to the lower end of the workpiece or descending from the lower end of the workpiece according to the processing width of the workpiece, thereby enabling a solid support for the workpiece. It relates to a double-headed milling device having an elevating lower clamp body capable of milling the minimum width of a workpiece.

In general, a milling device refers to a device that cuts a workpiece by rotating a cutting machine. It is configured to rotate and cut the workpiece while the workpiece is fixed on the table of the milling device. , Various groove cutting and other cutting processes are performed.

Of these milling devices, a milling device in which two cutting machines are provided to correspond to each other is called a double-headed milling device. This double-headed milling device is positioned so that the two cutting machines face each other on both sides, and the workpiece is positioned and fixed between them. This is a method of cutting the workpiece while moving forward and backward on the following two cutting machines, respectively, using the forward/reverse guide rail.Since the two cutting machines are simultaneously cutting both sides of the workpiece, cutting processing time can be shortened. do.

However, since such a conventional double-headed milling apparatus performs cutting in a state in which the workpiece is fixed by pressing only the central portion of the upper surface of the workpiece, there is a concern that the workpiece may move and the cutting may not be performed properly.

In addition, since auxiliary support means for cutting a workpiece having a width larger than that of the cutting machines on both sides is not provided, there is a problem that cutting work on a workpiece having a large width becomes impossible.

In order to solve the problem of such a milling device, a double-headed milling device provided with an extended base body, which is No. 20-0477624 for the registration office, has been devised, and the first moving body is positioned on the upper side of the first left and right moving body and the first left and right moving body. A first base connected to the left and right moving bodies and moved to the left and right by the first left and right moving bodies, a first forward and backward guide provided on an upper end of the first base, and a top surface of the first forward and backward guide, Connected to the second left and right moving body to be located on the upper side of the first cutting body that is forward and backward by a first forward and backward guide, a second left and right moving body positioned to face the first left and right moving body and the second left and right moving body A second base that is moved to the left and right by the second left and right moving body, a second forward and backward guide provided on the upper end of the second base, and a second forward and backward guide provided on the upper surface of the second forward and backward guide In a double-headed milling device consisting of a second cutting body that is advanced and retracted by a guide, the first cutting body and the second cutting body are separated from each other on one side of the upper end of the first base. The expandable base body is further provided, and the expandable base body is provided with a floor frame in close contact with the upper end of the first base and firmly fixed to the first base, and a connection frame protruding from the upper surface of the floor frame. A reinforcing rod that is seated on the upper surface of the connection frame of the reinforcing rod and bolted to the connection frame, a first position hole and a second position hole facing each other through each other, and a seating frame in which a workpiece is seated, And bolted, but the first positioning hole of the seating frame is located on the lower side, and the first positioning rod is raised and lowered toward the upper side of the first positioning hole, so that one end of the workpiece seated on the seating frame is at the first position. A first elevating body to be positioned by being hooked on the crystal rod, and bolted to the lower surface of the seating frame, and positioned at the lower side of the second positioning hole of the seating frame to place a second positioning rod toward the upper side of the second positioning hole. Work of the workpiece mounted on the seating frame by raising and lowering it It consists of a second elevating body that allows the side end to be positioned over the second positioning rod.

Such a conventional technique further includes an extension bracket in a double-headed milling device provided with two cutting bodies, so as to cut off the gap between the two cutting bodies as well as the cutting of the workpiece located within the gap between the two cutting bodies. It is also possible to cut the workpiece.

However, in the prior art, since cutting is performed by adjusting the gap of the workpiece by the extension bracket, it is difficult to connect or separate the extension bracket to the milling device.

Moreover, if the processing width of the workpiece that is processed at the same time on both sides is narrow, it is not possible to firmly support the lower end of the workpiece. As the other side has to be processed after processing, the processing time is delayed and there is a problem that it is impossible to process both sides of the double head milling device.
