Abstract

The invention discloses a compensation device of a high-precision positioning tool for workpiece machining. The compensation device includes a base, one end of the base is connected with a detection assembly, and the other end is connected with a fixing assembly; the detection assembly is used for detecting the position of a cutter and feeding back to a control center to adjust the cutter, and thefixing assembly is used for fixing the base and the detection assembly to a machining device. The compensation device is stable in structure, is flexible and reliable, and is convenient to disassemble and assemble; with the arrangement of a sealing protection device, a sensor can be protected from being polluted or damaged by the processing disintegrating slag at any time; a cleaning device is additionally arranged in the sealing protection device, the sensor can be guaranteed to be clean further, so that the precision of the sensor is guaranteed, and the compensation precision is guaranteed;in addition, the sensor is installed in an automatic telescopic device, the full-automatic control is achieved; the sensor is matched with the sealing protection device, so that the sensor is more intelligent; the fixing assembly is arranged at the tail of the base, so that the compensation device can be installed outside various large complex machine tools, and the universality is high.

Description

technical field

[0001] The invention belongs to a tool compensation device, in particular to a high-precision positioning tool compensation device for workpiece processing. Background technique

[0002] Tool wear is a ubiquitous and inevitable phenomenon in mechanical processing. Tool wear will change the position of the tool relative to the workpiece and affect the quality of the processed workpiece. Therefore, it is necessary to monitor the wear of the tool in time and adjust and compensate its position in time.

[0003] The Chinese patent with the publication number CN 1347793A discloses "the external active compensation method and device for the axial deflection of the rotating spindle tool. The external active compensation device is independent of the main shaft and includes: a sensor, an extension frame, several Actuator, and a control module. The extension frame extends between a base and a position near the tool, and the sensor is combined with the end of the extensi...
