Abstract

PURPOSE: A workpiece turning over device turns over a workpiece, thereby improving a working speed and efficiency. CONSTITUTION: An inverting member(7) is installed to upwards a tool rest via an attaching bracket(6). A free end(10) having a clamp(9) is extended and installed at the center axis(8) of the inverting member(7). A base member(11) separated under the clamp(9) is mounted on the attaching bracket(6) of the inverting member(7). The clamp(9) contains and supports a workpiece(2) put on the base member(11) and rotates it to vertical/horizontal directions. Thus, a complete machining to the workpiece(2) is implemented by turning over the workpiece(2).

Description

Work turnovering device of a vertical lathe}

The present invention relates to a device installed on the vertical shelf to invert the upper and lower parts of the work, in particular, the first vertical processing of the workpiece bitten by the chuck and then inverted up and down in the inverting table to be bitten by the chuck again to make the secondary processing It relates to a workpiece upside down device of a lathe.

In general, in a machine tool such as a vertical lathe, the workpiece is held by a chuck and moved to the side of the tool bar. However, when the workpiece to be machined has to be machined in both the upper and lower parts, the upper or lower part of the workpiece is first processed in the tool bar. Next, the operator changed the position of the raw portion of the workpiece, and the remaining raw portion was to be worked on the tool post.

However, the conventional method of processing such a workpiece has a disadvantage in that the work speed and efficiency are naturally reduced because the worker inverts the workpiece to be processed one by one, and further reduces the image of the product of the vertical shelf to the worker. There was a problem dropping.

Therefore, the present invention has been invented in view of the above-mentioned conventional problems, and when the workpiece is to be processed both at the upper and lower parts of the tool post, the position of the upper and lower parts of the workpiece is reversed by a simple device while improving the working speed and efficiency. It is an object of the present invention to provide an up-and-down reversing device of a vertical vertical lathe that also improves the merchandise.

3: headstock 4: chuck

5: Tool stand 6: Mounting bracket

7: inversion band 8: central axis

In order to achieve the above object, the present invention, while installing the inverting table through the mounting bracket toward the upper side of the tool bar, the free end of the inverted stand is provided with a clamp for holding the workpiece and the free end is the center of the reverse table It is possible to rotate 180 ° in the vertical direction at the top of the axis and rotate 180 ° in the horizontal direction.

And the pedestal for placing the workpiece conveyed by a known transfer device is fixedly spaced apart at a predetermined interval downward from the free shaft leading end of the inversion.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall side view of a vertical lathe to which the present invention is applied, and FIG. 2 is an enlarged side view showing a top and bottom reversing apparatus of a workpiece which is a main part of the present invention.

As shown in Fig. 1, the vertical lathe is formed by aligning the workpieces 2 stored in the workpiece holder 1 with the chuck portions 4 of the spindle head 3 one by one. After moving in the direction, the first and second machining operations are performed on the tool post 5, where an inverted counter 7 is installed through the mounting bracket 6 toward the upper side of the tool post 5. A free end 10 having a clamp 9 extends and is installed at a point about the central axis 8 of the base 7, and extends downwardly to the lower side of the clamp 9 mounted at the tip of the free end 10. The pedestal 11 on which the work 2 is spaced apart from each other has a structure provided in the mounting bracket 6 of the inversion table 7.

In addition, the clamp 9 mounted on the free end 10 of the inverting table 7 holds the workpiece 2 mounted on the pedestal 11 so that the clamp 9 can rotate in the vertical and horizontal directions.

Next, the operation of the vertical upside down device of another vertical lathe to the present invention will be described.

First, as shown in the known manner, the workpiece 2 stored in the workpiece storage stand 1 is held by the chuck portion 4 of the spindle 3 and moved in the direction of the arrow along the feed system of the guide rail. Go to the) side to perform the first machining work.

After the first machining operation of the workpiece 2 is completed, the chuck unit 4 places the semi-processed workpiece 2 on the pedestal 11 of the reversing device by a feed system. The clamp 9 mounted on the free end 10 of the inverting table 7 then holds the workpiece 2 in the state of the dashed line in FIG. 2 so that the central axis 8 is perpendicular to the point 180. When rotated by °, the workpiece 2 by the clamp 9 shown by the solid line of FIG. 2 maintains a state in which the lower portion thereof is inverted toward the upper side.

In this state, the workpiece 2 is rotated 180 degrees in the horizontal direction so that the unprocessed portion of the workpiece 2 is placed on the pedestal 11 while maintaining the upper side thereof. Then, when the chuck portion 4 of the headstock 3 again bites the workpiece 2 and enters the secondary processing step, the headstock 3 moves along the feed system to move the processed workpiece. It is intended to be stored in the work holder 1.

As described above, the present invention has the advantage of improving the reliability and productability of the product while improving the working speed and efficiency by helping to perform a complete machining operation by inverting the workpiece to be processed in the vertical lathe up and down.
