Description

[Detailed Description of the Invention] The present invention relates to an improvement in an annular article processing machine that processes a plurality of annular objects, such as gears, stacked together and performs gear cutting, polishing, etc. on the outer periphery thereof.

Conventionally, for example, in a gear cutting machine, a plurality of ring-shaped materials (usually about 2 to 5 pieces) that have been lathe-processed in advance are mounted on a turntable such as a gear cutting machine, and gears are cut simultaneously on the outer periphery of each ring-shaped material. Alternatively, tooth surface polishing and other processing is attempted to improve efficiency compared to machining one piece at a time, and improvements in cutting tools and polishing tools are also being used to reduce net machining time. be.

However, it takes a long time to perform so-called setup work such as stacking a plurality of annular materials on the turntable and fixing them while centering each one, and removing the completed annular material. Even in the case of ~3 annular sheets, about 3 pieces were required, which reduced the operating rate of the processing machine accordingly.

In view of the above-mentioned conventional circumstances, the present invention is equipped with two or more sets of floating tables in which a plurality of annular materials are stacked and fixed in advance at the center, and each floating table can be freely replaced and attached to and detached from the turntable. An embodiment of the present invention will be described below with reference to the drawings.

Fig. 1 is a front view partially shown in cross section, and Fig. 2 is an exploded perspective view of the floating table.The annular product processing machine that processes annular quantities 1 such as gears rotates horizontally with the rotation axis vertical. A processing head 4 is equipped with a turntable 2 and is slidably provided in the vertical direction guided by the side heads 3.
A gear cutting or polishing tool 5 is attached to process the outer circumference of the annular object 1, and in the above-mentioned known annular object processing machine, a tool 5 for cutting or polishing is attached to the upper surface of the turntable 2 to align the center thereof. The outer periphery of the disk portion 9 of the floating table 8, which will be described later, is reduced or expanded in radial direction by means of a cam, a lever set, or a screw with a three-way claw on the outer periphery. The floating table 8 is provided with a conical convex portion 10 corresponding to the conical concave portion 6 at the center of the lower surface of the disk portion 9, and a conical convex portion 10 corresponding to the conical recess 6 is provided at the center of the upper surface of the disk portion 9. For example, a bolt 12 whose lower end is fixed, a presser metal fitting 13 such as a washer or a beam, and a nut 14
An annular article fixing device 11 is provided, and surface plates 15 radially fixed at three locations are used to suspend and stably support the annular article 1 from the upper surface of the floating table 8.

Two or more sets of floating tables 8 having the above structure are provided, and each floating table 8 can be freely replaced with a conical concave portion 6 and a conical convex portion 1 on the turntable 2.
0 and align the clamping device 7.
It is provided so that it can be attached and detached freely.

While one set of the floating tables 8 is mounted on the turntable 2 of the annular product processing machine and the outer circumference of the annular product 1 is being processed, a plurality of annular shapes are placed on one or more other sets of floating tables 8. After stacking the products 1 and aligning the centers using a centering device (not shown), fixing device 1
1, and when the machining is completed, the clamping device 7 is loosened, the floating table 8 is removed, and the floating table 8 to which the annular product 1 is previously fixed is installed in its place, and machining continues.

Therefore, the work of mounting each floating table 8 onto the turntable 2 and preparing the sushi takes about 5 minutes in the case of the embodiment.

Since the present invention is constructed as described above, while a ring-shaped item is being processed using one set of floating tables, the next ring-shaped item to be processed can be set on the other floating table with sufficient time and accuracy. Since it is only necessary to attach and detach each floating table to and from the turntable, setup work is simple and can be done in a very short time, which improves the operating rate of the processing machine and is extremely effective.

Note that the present invention is not limited to the above-mentioned embodiments, but can also be applied to processing machines such as broaching machines and milling machines.
