Roller type low-frequency vibrational drilling worktable

Abstract

The invention provides a roller type low-frequency vibrational drilling worktable 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 table plate. The upper end of the lower box body abuts and is connected with the lower end of the upper box body by means of fastening bolts. The left end and the right end of the rotary driving shaft are respectively rotationally arranged on the left sides and the right sides of the lower box body and the upper box body. The linear bearing of which the lower end extends into the upper box body is arranged at the top of the upper box body. The linear driving shaft penetrates the linear bearing in a sliding manner. The upper end of the linear driving shaft is fixedly connected with the lower surface of the table plate. A fixed frame is arranged at the lower part of the linear driving shaft. A compression spring is arranged between the lower surface of the top of the lower box body and the fixed frame. The lower end of the linear driving shaft is in transmission connection with the rotary driving shaft through a low-frequency vibration mechanism. The roller type low-frequency vibrational drilling worktable can realize stepless adjustment of the vibration frequency, the low-frequency vibration amplitude can be adjusted, a set of available vibration and drilling parameters can be conveniently found, and processed parts can be processed.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, in particular to a roller-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 are very harsh...

AI Technical Summary

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
