Ultrasonic-assisted tapping device

Abstract

The invention provides an ultrasonic-assisted tapping device. The ultrasonic-assisted tapping device comprises a workbench, an ultrasonic tapping mechanism, a feeding mechanism and a material clamping mechanism, wherein the ultrasonic tapping mechanism, the feeding mechanism and the material clamping mechanism are arranged on the workbench. The material clamping mechanism comprises a fixed seat, a material clamping plate rotationally arranged on the fixed seat, a first driving mechanism for driving the material clamping plate to rotate, and a material ejecting plate. A vertical sliding rail is arranged on the workbench, and the material ejecting plate is connected with the sliding rail in a sliding mode. A plurality of material clamping parts are arranged on the material clamping plate, and the material ejecting plate is arranged below the material clamping parts. The feeding mechanism is arranged between the material ejecting plate and the material clamping parts and connected with the top end of the material ejecting plate. The feeding mechanism, the material clamping mechanism and the ultrasonic tapping module are combined, meanwhile, the material clamping mechanism is provided with the plurality of material clamping parts, clamping operation and tapping operation can be conducted at the same time, the time between two times of tapping operation is shortened, and the automatic tapping efficiency is improved; and a part is clamped through the material clamping parts, the machining precision is improved, and the situation that the part vibrates and damages a tool is avoided.

Description

technical field [0001] The invention belongs to the technical field of tapping processing, and more specifically relates to an ultrasonic-assisted tapping device. Background technique [0002] Composite materials, engineering ceramic materials, and superhard metal materials are widely used because of their excellent properties such as high hardness, high strength, high wear resistance, high corrosion resistance, and high temperature resistance. However, due to the poor toughness and brittleness of these brittle and hard materials, traditional machining techniques may be difficult or impossible to process, which limits their application to a certain extent. Hole making or tapping technology is one of the key technologies for the wide application of these hard and brittle materials, but at present, the hole making or tapping technology for these difficult-to-machine materials has low processing efficiency, severe tool wear, and easy to split materials. Phenomena such as crack...

However, it can only work as a device, and the overall processing efficiency is slow, and it cannot effectively position and clamp the parts, which will affect the machining accuracy; in addition, if the parts cannot be effectively positioned and clamped, the tool will cause the parts to break during the processing. Large vibration, hitting the cutter head, which is easy to damage the cutter
