A device and method for calibrating the shot blasting position of a shot blasting machine

Abstract

The invention discloses a shot peening position calibration device and method of a shot blasting machine. The device includes a calibration block and a calibration simulation gun for simulating the shot blasting path; the calibration block and the calibration simulation gun are both provided with a connection end and a calibration end; the calibration block The connection end is connected with the central positioning hole of the machine tool, and the connection end of the calibration simulation gun is connected with the nozzle of the shot blasting machine; when the shot blasting position of the shot blasting machine is calibrated, the calibration end of the calibration block is aligned with the calibration end of the calibration simulation gun. The present invention changes the conventional spray gun calibration method, and uses the spray gun position calibration device to check the nozzle position before shot peening, thus avoiding the quality defect of insufficient shot peening coverage caused by inaccurate nozzle position during shot peening, and accurate calibration The trajectory of the nozzle during the shot peening process is clearly defined, and the first pass rate of shot peening coverage is improved. Simultaneously, the device of the invention has a simple structure, is convenient for production and processing, has low cost, and is suitable for popularization and use.

Description

technical field [0001] The invention belongs to the field of shot peening, and relates to a shot peening position calibration device and method of a shot peening machine. Background technique [0002] In the existing shot blasting process, due to equipment maintenance, replacement of the spray gun and bracket system, or special circumstances such as gun collision during shot peening experiments, it is necessary to re-adjust and reset the spray gun, and each adjustment and reset depends on the mechanical function of the equipment. It is realized by returning to zero, without considering the influence of the assembly clearance such as the nozzle bracket. This will cause the nozzle position to change from the originally programmed position. The change of the shot peening position has a great influence on the coverage of the part, especially in special positions such as small ring grooves and assembly holes, the accuracy of the position is very important. [0003] When peening...
