Description
Technical Field
The utility model relates to the field of bolt processing, in particular to a feeding suction head device and a thread rolling machine.
Background
In order to ensure the safety and reliability of the aircraft, the aviation standard component bolt adopts high standard requirements, and the bolt is strictly subjected to size precision, thread ending and tooth type metallographic phase, so that the bolt is accurately positioned and processed. At present, a vertical or horizontal thread rolling machine is mainly adopted for bolt rolling, and a mechanical clamping jaw, a rubber clamping jaw, a vacuum chuck and the like are adopted for bolt feeding.
However, the mechanical clamping jaw has higher requirements on the appearance of the bolt head type, and is mostly used for a flat round head type which is easy to clamp; the mechanical clamping jaw mode is complex in structure, high in processing cost and troublesome in mold changing, and is easy to clamp and damage a workpiece, so that the appearance quality problem of the aviation piece is caused. The rubber jaws can grip a multi-headed bolt, but can experience workpiece deflection due to head misalignment (e.g., hex head, countersunk head). The vacuum chuck can be used for various head shapes, but requires the end face of the workpiece to be adsorbed to be smooth, and the workpiece is rotated vertically and rapidly to be easy to drop transversely. In addition, in order to improve the tooth-shaped metallographic quality of the aviation piece, warm rolling processing (about 400 degrees) is adopted in most cases, and the workpiece falls off due to insufficient suction force when the rubber clamping jaw and the vacuum chuck are used for long-term working. The countersunk bolt is clamped by adopting a rubber clamping jaw and a mechanical clamping jaw mode, and the clamping workpiece is inclined due to the fact that the clamping surface is too small. In particular, when a bolt is processed by a warm rolling horizontal thread rolling machine, a traditional mechanical clamping jaw, a rubber clamping jaw and a vacuum chuck feeding mode cannot ensure that a workpiece is rotated vertically and rapidly to be horizontally and accurately and directionally transported. At present, if a horizontal Wen Gunsi machine meets the requirements of processing various head bolts such as a hexagon head, a countersunk head and the like, different feeding clamping tools are required to be equipped, the mold changing is complex, and the efficiency is low.
