Rotary type transducer main shaft device of supersonic vibrated drill

Abstract

The invention discloses a main shaft device of a rotary type energy converter for supersonic vibration drilling, which comprises a main shaft component (1), an electric machine driving component, an energy converter power supply component (5) and a shell component; a housing screw (510) of the energy converter power supply component (5) is connected to a screw hole (131a) of the main shaft (103) of the main shaft component (1); and a slave driving belt wheel (32) of the electric machine driving component is sleeved on the main shaft (103) of the main shaft component (1), and an initiative belt wheel (31) and the slave driving belt wheel (32) are in transmission connection through a driving belt (3). The rotary ultrasonic energy converter main shaft device can be arranged on a bench drill, and the device can process workpieces when feed control components are added thereto, so that the device can lead an electric motor of the system to operate and provide electricity for the ultrasonic energy converter by using a slip ring (502a), thereby generating supersonic vibration along the axial direction of the main shaft while ensuring high-speed rotation of the the main shaft (103), and obtaining the compound movement of the rotary supersonic vibration by overlapping; a bit or a reamer are clamped at an end of the main shaft, thereby realizing the rotary supersonic vibration drilling or reaming.

Description

technical field [0001] The invention relates to a spindle device, more particularly, a spindle device suitable for ultrasonic vibration drilling. The spindle device can generate rotary ultrasonic vibration, and belongs to metal cutting processing and metal cutting equipment components. Background technique [0002] Under the existing technical conditions, the most widely used and most practical method in the small hole processing of difficult-to-machine materials (such as glass, engineering ceramics, metal matrix composites, etc.) is the ordinary drilling process, but when this method is used, Drills are prone to deviation, poor centering, poor chip removal, difficult heat dissipation, and many exit burrs, which are difficult to meet the needs of small hole precision and ultra-precision machining. However, special processing methods (electric spark, laser, electron beam, ion beam, electrolysis, etc.) have poor hole roundness and aperture accuracy, poor surface roughness, exp...

AI Technical Summary

Problems solved by technology

In the design of existing rotary ultrasonic processing equipment, in order to avoid the impact of vibration on peripheral equipment, most of them design the transducer and the rotary spindle as two parts, the spindle is hollow, and the transducer and the rotary spindle are connected by a thin flange. This increases the complexity of the mechanism to a large extent, making it difficult to guarantee the rotation accuracy of the spindle.
