Spot facing device

Abstract

The invention provides a dimple device which comprises a base plate, a spindle feeding system, a position feedback system and an electrical control system. The spindle feeding system comprises an electrical spindle, a cutter handle, a cutter, a linear guide rail, an electrical spindle retainer, a driving motor and an optical grating. The position feedback system comprises a linear slide rail, a slide block, a connecting plate, a pressing head, an air cylinder and a micro-pulse displacement sensor. The electrical control system comprises an analog quantity / digital signal conversion module, a programmable controller and a numerical control system. The micro-pulse displacement sensor serves as an element for detecting the surface position of a dimple workpiece, the optical grating serves as an element for detecting the position of the cutter, and acquired data are transmitted to the numerical control system through the analog quantity / digital signal conversion module and the programmable controller. The problem that shaft position control is performed in the numerical control system by referring to other position information is solved, accordingly the dimple depth accuracy is ensured, and the problem of the dimple depth control of the numerical control system serving as a control core element is solved.

Description

Technical field [0001] The invention relates to the field of automation equipment and manufacturing, in particular to a countersink device. Background technique [0002] In modern automation equipment and manufacturing, the processing requirements for large and complex parts have become more and more extensive. Among them, the hole machining accuracy of large thin-walled parts, especially the machining accuracy of countersink holes, determines the accuracy and reliability of subsequent assembly links. In the countersinking process of large thin-walled parts, due to the difference between the workpiece manufacturing accuracy and the digital model, the position of the workpiece surface during actual processing is often unknown. Measurements must be carried out to determine the position of the workpiece, and then calculate the initial advancement of the tool. Give depth. After determining the surface position of the workpiece, although the initial feed depth of the tool is determi...
