Abstract

The invention relates to the field of a machining center box type part jig calibration and aims at providing a box type part jig accuracy calibration device and an accuracy calibration method. The box type part jig accuracy calibration device comprises an accuracy calibration base and an infrared probe system. The accuracy calibration base comprises a bottom plate and a vertical calibration plate, wherein the bottom plate is provided with at least two connecting blocks at the lower end surface, and the vertical calibration plate has one end surface provided with a calibration surface perpendicular to the bottom plate and is connected to the bottom plate at the lower end. The calibration surface is provided with at least a calibration hole penetrating through the other end surface of the vertical calibration plate. The lower end surface of each of the two connecting blocks is provided with a connecting through hole penetrating through the upper end surface of the bottom plate and a positioning hole. The infrared probe system comprises an infrared probe with a knife shank and a data transmission unit and a data receiver electrically connected to a controller of a machining center. The box type part jig accuracy calibration device is small in accuracy calibration errors and free of fouling and abrasion affecting calibration results.

Description

technical field

[0001] The invention relates to the field of calibration of fixtures for box-like parts in a machining center, in particular to a precision calibration device and a precision calibration method for box-type fixtures. Background technique

[0002] The invention of Chinese patent application number: CN201210170359.4 discloses a machining center calibration fixture, including a shaft, a radial bracket and a moving slider, the radial bracket is fixed on the end of the shaft, and the moving slider is installed on the radial To the bracket, move the slide to mount the dial indicator. This alignment jig is suitable for quickly centering holes. Fixtures for processing box parts installed on the turntable of the machining center, in the early stage of assembly with the machine tool, maintenance personnel regularly check the fixtures, and measure the loss of accuracy after accidents such as collision and interference of the equipment provide a basis for restoring the ...
