Abstract

PURPOSE:To retrench the production cost of a helical rack bar with different directions of tooth twisting, or the like, by making it possible to process the helical rack bar while changing the direction of tooth twisting, without replacing a guide. CONSTITUTION:A workpiece not shown in the drawing is held by a work chuck 11. A work carrier 5 is moved by a radial feed motor 6 so that the workpiece is placed at the front or rear portion of the axis of a cutting spindle 3. A feed table 9 is disposed in a prescribed position. Motors 13, 15 are then driven under numerical control, at the same time as each other, depending on the reciprocation of a pinion cutter 4, to subject the workpiece to an axial feed and a circumferential rotation simultaneously so as to shape helical teeth sequentially.

使用している。Generally, racks such as rack bars used in automobile steering mechanisms are generally machined using a special machine, but they are also machined using a gear shaping machine. When using a gear shaping machine, attach a rod-shaped workpiece support means to the workpiece carrier and remove the workpiece. The shape is shaped by the reciprocating motion of the binion cutter while feeding intermittently in the axial direction, but when shaping a rack such as a helical helical gear, a dedicated work guide is used to feed the workpiece while rotating it completely. are using.

In the same car model, only the twisting direction of the teeth is reversed from left to right due to the difference between right-hand drive and left-hand drive, but all other specifications are the same 1. Conventionally, the twist direction of the teeth is different. When forming with the same gear shaper for all racks, dedicated work guides are used interchangeably on the left and right sides, and it takes a lot of effort and a long time to do this replacement work and the fine adjustments that come with it. Moreover, the problem is that the processing cost of the rack is high due to the use of exclusive and expensive work guides for each of the left and right sides.

する。The present invention takes into account the above-mentioned conventional problems, and eliminates the need to replace work guides even when molding racks with different twisting directions of the teeth. The structure of the present invention is to provide a gear shaping machine that reduces the amount of labor required for the work and requires a dedicated work guide mounting stand for each of the left and right sides. A workpiece feed table is provided on the XF-plane substantially perpendicular to the cutter axis direction, and the core feed table is provided with a middle support stage for the workpiece, and the feed table moves in the axial direction and radial direction of the workpiece. It is characterized in that it is freely movable and can be positioned at symmetrical machining positions on both sides of the cutter shaft.

製造コストが著しく削減される。The gear shaping machine of the present invention is configured as described above, and is equipped with a feed table that is slidable in the feed direction of the work carrier and in a direction orthogonal thereto, and supports a bar-shaped work on the feed table. By providing a work guide and making it possible to shape the bar-shaped workpiece while positioning it on both sides of the cutter spindle axis, it is possible to cut the workpiece when machining a rack with helical teeth. It is possible to process a rack in which only the helix direction of the teeth is completely changed without replacing the guide, changing the setup of the 11 products, or making fine adjustments. Since there is no need to manufacture a separate work guide in total, the manufacturing cost of rack manufacturing using a gear shaping machine is significantly reduced.
