Description

[Detailed Description of the Invention] Technical Field This invention relates to a partition cover between the main spindles of a two-spindle, two-saddle NC lathe.

Conventional technology In a 2-spindle, 2-saddle NC lathe, when machining a workpiece gripped by one spindle and attaching/detaching the other workpiece, chips during cutting may scatter and the operator may be unable to attach/detach the workpiece. A partition cover is provided between the spindles to prevent interference and to prevent chips from both sides from mixing. Since this cover is fixed vertically, there is little space between the cover and the spindle, making it difficult to attach and detach the workpiece.

Purpose Therefore, this idea was created in view of the above,
The objective is to provide a partition cover that provides a wide space in front of the spindle when attaching and detaching workpieces for each spindle, and provides good workability.

SOLUTION: A vertical partition cover is provided that separates the two main shafts, and the partition cover is pivotably supported by a hinge at its base.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. On the upper surface of the bed 1, two headstocks 3 rotatably supporting a main shaft with a chuck 2 fitted at the tip thereof are fixed in parallel and perpendicular to the longitudinal direction of the bed. Chips from the gripped workpiece protruding further forward do not get caught in the bed 1, but slide on the cover 4 in front of the bed and are collected in the chip receiver. Then, on the bed sliding surfaces on both the left and right sides of the headstock, a saddle controlled by the X-axis by an NC (not shown) is placed, and on top of that, a tool rest (not shown) with a turret tool rest provided at the front end so as to be rotatable and indexable. Z-axis control is performed by NC. A partition cover support 5 is installed in the center between the chuck parts 2, 2, facing forward and perpendicular to the bed 1, and is attached to the support 5 by upper and lower hinges 6, 6 whose pivot axis is perpendicular to the bed 1. The partition cover 7 is pivoted so that it can be pivoted left and right to open. The partition cover 7 is fixed at a central position by fixing screws 10 and 11 screwed into the upper support 8 and the lower support 9. Further, splash guards 12, 12 that cover the front and upper surfaces of the main shaft are provided so as to be able to be opened and closed to the left and right on the rail 13, respectively.

Since the cover is configured in this way, when you want the chuck 2 to grip a workpiece, open the splash guard 12 to the left and right, loosen the fixing screws 10 and 11, and open the partition cover 7 to the side where you are not working. The front space becomes wider. When the work is finished, the partition cover 7 is positioned in the center and fixed with fixing screws 10 and 11.

Effects As detailed above, this design allows the partition cover installed between the spindles to be opened by tilting it to the left or right using a hinge, which increases the space in front of the spindle and eliminates interference during work. This has the effect of improving workability.
