Problems solved by technology

The compensation value set by timing compensation and fixed piece compensation is constant, but due to the influence of factors such as the processing environment or individual differences in tools, this tool compensation method is often not accurate, and the phenomenon of over-compensation or under-compensation often occurs

Embodiment 1

[0035] Such as Figure 1 to Figure 4 The shown online detection and intelligent compensation tool wear device for CNC lathe includes: measuring arm mount 2, measuring arm 3, tool tip contact sensor 4, measuring arm barrier 5, window 6 and data processing unit.

[0036] The measuring arm mounting seat 2 is arranged behind the self-centering chuck 1 of the machine tool. The self-centering chuck 1 is used to clamp the workpiece. The measuring arm mounting seat 2 has a mounting pin 20 . The measuring arm 3 is rectangular, one end of the measuring arm 3 is rotatably connected to the measuring arm mount 2 through the mounting pin 20, and the other end has a tool tip contact sensor 4, and the tool tip contact sensor 4 has a measuring tool 7 in the X direction and Tetrahedral probe in the Z direction. The working position of the measuring arm is that the four faces of the four-sided probe of the tool tip contact sensor 4 are in a vertical state, and the tool tip contact sensor 4 is l...

Embodiment 2

[0048] Such as Figure 5 As shown, the difference between embodiment 2 and embodiment 1 is that the measuring arm barrier 5 is a baffle plate, which reduces the material consumption and can also isolate iron filings and cutting fluid from the measuring arm 3 .

[0049] The online detection and intelligent compensation control flow charts of Embodiments 1 and 2 of the present invention are as follows Image 6 As shown, the position data of the tool 7 measured last time in the X and Z directions are defined as reference data, and the position data of the tool 7 measured this time in the X and Z directions are defined as actual measurement data. Comparing the two data, if there is a difference in the position data of the tool 7 in the X direction, the CNC lathe will automatically compensate according to the difference; The same is true for the compensation control method.

[0050] Timing compensation and fixed piece compensation are to set a constant compensation value, such as...

Abstract

The invention discloses an apparatus for online testing a numerical control lathe and intelligently compensating cutter abrasion, which comprises a measuring arm mounting base set on the back of a self-centering chuck of a lathe and a measuring arm used for measuring the cutter abrasion amount, wherein the measuring arm is a right angle shape; one end of the measuring arm is rotatingly connected to the measuring arm mounting base and the other end thereof is provided with a cutter tip contact sensor; the apparatus also comprises a measuring arm block piece used for separating the measuring arm and the lathe processing environment and a data processing unit that is used for recording and comparing the positions of the cutter at the X direction and the Z direction tested by the cutter tip contact sensor; the invention also discloses a method for online testing the numerical control lathe and intelligently compensating the cutter abrasion; by operating the cutter to be close to and contact with the corresponding surface of an all-side probe of the cutter tip contact sensor, the data processing unit records the position datum of the cutter at the X direction and the Z direction; and two adjacent datum are compared to calculate the abrasion amount of the cutter and the lathe is controlled to automatically compensate the abrasion amount. By adopting the apparatus and the method provided herein, the intelligent and accurate compensation to the cutter can be realized.

Description

technical field [0001] The invention relates to the field of numerical control lathes, in particular to a device and method for on-line detection and intelligent compensation of tool wear of a numerical control lathe. Background technique [0002] Tool wear is a common phenomenon in mechanical processing. Tool wear will affect the quality and tolerance of the processed workpiece. Therefore, in order to improve the quality of the processed workpiece and reduce the processing cost, the part of the tool wear should be compensated by adjusting the initial processing position of the tool. . The traditional tool compensation method is timing compensation or fixed piece compensation by statistical analysis method. The so-called timing compensation means that after the tool works for a specific time, the tool is compensated with a constant amount according to the statistical tool wear. The so-called fixed-piece compensation means that after the tool processes a specific number of ...
