Background
Machine tools are machines for manufacturing machines, also called machine tools or machine tools, which are conventionally referred to as machine tools for short.
The machine tool for gear machining comprises a gear hobbing machine tool, a gear shaping machine tool and a gear grinding machine tool. When a gear is machined by adopting a hobbing machine tool, a gear shaping machine tool and a gear grinding machine tool, the gear to be machined is generally required to be clamped on a workbench of the machine tool, different clamps are required to be adopted for machining different gears, and when the gear is clamped, the gear is generally clamped in a tensioning mode. This allows the lower end of the clamp to be provided with a force application bar, typically extending through a relief hole in the table to the underside, to apply the pulling force. The force application rod and the cylinder piston rod are connected by a pull rod. When different gears are machined, different clamps are adopted, the lengths of the force application rods in the different clamps are different, and therefore different pull rods need to be replaced; and the diameter of the force application rod is different for different clamps, which also requires the replacement of different rods. The versatility of the tie rod is poor, which makes it necessary to arrange a plurality of tie rods, resulting in waste. And changing the pull rod also wastes time and labor.
