Groove type low-frequency vibration drilling workbench

Abstract

The invention discloses a groove type low-frequency vibration drilling workbench which comprises a driving motor, a lower box body, an upper box body, a rotary driving shaft, a linear bearing, a linear driving shaft and a platen. The upper end of the lower box body and the lower end of the upper box body are in butt connection through a fastening bolt. The left end and the right end of the rotary driving shaft are rotationally arranged on the left side and the right side of the lower box body and the upper box body respectively. The top of the upper box body is provided with the linear bearing with the lower end stretching into the upper box body. The linear driving shaft penetrates in the linear bearing in a sliding mode. The upper end of the linear driving shaft is fixedly connected with the lower surface of the platen. The lower portion of the linear driving shaft is provided with a fixing frame. A compression spring is arranged between the lower surface of the top of the lower box body and the fixing frame. The lower end of the linear driving shaft and the rotary driving shaft are in driving connection through a low-frequency vibration mechanism. According to the groove type low-frequency vibration drilling workbench, stepless adjustment for the vibration frequency can be achieved, the amplitude of low-frequency vibration can be adjusted, a set of available vibration drilling parameters can be conveniently found, and a to-be-machined part is machined.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a groove-type low-frequency vibration drilling workbench. Background technique [0002] Holes are the basic shapes and surfaces that make up mechanical parts, and hole processing is the most common processing technology in mechanical processing. Relevant data show that: about 30% of the machining is the machining of holes, of which about 80% are processed by cutting, and the amount of metal removal in hole machining accounts for about 1 / 3 of the total amount of metal removal in machining . [0003] Deep hole processing is an important branch in the field of mechanical processing, and has a wide range of applications in defense industry, oil mining, aerospace, machine tools, automobiles and other industries. Deep hole processing is very different from turning and milling. In the process of deep hole processing, the cutting conditions of the drill bit ar...

Problems solved by technology

[0004] However, the popularization and application of vibration drilling technology is not very good, the main reason is that it is difficult to change the vibration processing parameters, and there is no better general vibration excitation device, which cannot adapt to various processing occasions and conditions
