Background
Ultrasound is a sound wave with a frequency higher than 20000 hz, so called because its lower frequency limit is higher than the upper limit of human hearing. The directional property is good, the penetrating power is strong, more concentrated sound energy is easy to obtain, the propagation distance in water is long, and the device can be used for distance measurement, speed measurement, cleaning, welding, stone breaking, sterilization, disinfection, machining and the like. The ultrasonic machining method is a method of applying ultrasonic vibration to a tool or a workpiece in a certain direction to perform vibration machining. Ultrasonic machining technology has been rapidly developed in recent decades, and has achieved significant effects in the machining of hard materials.
Ultrasonic hole punches are one application of ultrasonic waves in machining and manufacturing. The ultrasonic perforating machine can perforate on the surface of hard and brittle materials such as glass, engineering ceramics, quartz, marble and the like. The optical fiber manufacturing industry needs to drill deep holes on an optical fiber preform rod according to the process, and the hole depth reaches more than 300 mm. This requires that the tool must maintain a high degree of straightness. Generally, the punching tool is manufactured by the following steps: firstly, cutting a straight steel pipe to the length required by a cutter; then, straightening the steel plate for one time; after straightening, plating emery on one end of the steel pipe. However, the cutter after one-time straightening cannot meet the requirement of punching, and cannot be used. At present, due to the fact that no special cutter straightening tool exists, workers find that the cutter is not straight when punching is conducted, and experienced workers often conduct straightening in a mode that the cutter is pulled off by hands. The mode not only lags behind, but also consumes time and influences the working efficiency. When the cutter is broken off, the radial clearance of the main shaft of the perforating machine is increased, and the perforating precision of the perforating machine is influenced. In order to solve the defects of the traditional ultrasonic perforating machine straightening method, the special cutter straightening mechanism for the ultrasonic perforating machine is provided, and the precision and the efficiency of cutter straightening of the perforating machine are greatly improved.
