A first table (1) slidable leftwards and rightwards of a gear finishing machine and a second table (2) slidable forwards and rearwards of the machine are disposed in an overlapped relationship such that one of the tables is mounted on the top of the other table. Of these tables, the upper table is guided by a horizontal guide member (3) which is adapted to be rotated to any desired angular position and to be clamped at such position. A feed motor (5) drives the first table to slide. For sliding the table assembly along a diagonal direction, the angular position of the guide member is adjusted so that it extends along such direction. A horizontal stability of the table assembly is secured without employing a conventional parallel link mechanism. The table assembly is driven to slide so as to pass the center of machine so that an accuracy of gear finishing is assured.
In a gear finishing machine having a first horizontal axis extending leftwards and rightwards of the machine and a second horizontal axis is extending forwards and rearwards of the machine, said first and second horizontal axes being perpendicular to each other and passing a point on a vertical center axis of the machine, a table sliding apparatus which comprises:
In a gear cutting machine having a first horizontal direction extending leftwards and rightwards of the machine and a second horizontal direction extending forwards and rearwards of the machine, a table traversing apparatus comprising a first horizontal table (1) mounted for traversing along said first horizontal direction, a second horizontal table (2) mounted for traversing along said second horizontal direction, one of said tables being mounted for traversing on top of and relative to the other of said tables, said two horizontal directions being transverse to each other, guide means comprising a horizontal guide member (3) in engagement with the upper one of said tables for guiding said upper one of said tables during horizontal traversing thereof, said guide member (3) being angularly adjustable about a vertical axis to adjust the direction of traversing movement of said upper one of said tables, a releasable clamp (42) for preventing rotation of said guide member (3) when clamped, means (4) for angularly adjusting said guide member (3) when unclamped, and a feed motor (5) drivably connected to one of said tables for driving said one of said tables to traverse.
