Device and method for calibrating shot blasting position of shot blasting machine

Abstract

The invention discloses a device and method for calibrating the shot blasting position of a shot blasting machine. The device comprises a calibration block and a calibration simulation gun used for simulating a shot blasting path. Connection ends and calibration ends are arranged on the calibration block and the calibration simulation gun. The connection end of the calibration block is connected with a center positioning hole of a machine tool, and the connection end of the calibration simulation gun is connected with a 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 and the calibration end of the calibration simulation gun are aligned. A conventional spray gun calibration manner is changed, a spray gun position calibration device is adopted for calibrating the position of the nozzle before shot blasting, thus, the quality defect that the shot blasting coverage rate is insufficient as the position of the nozzle is not precise during shot blasting is avoided, the movement track of the nozzle in the shot blasting process is precisely calibrated, and the one-time percent of pass of the shot blasting coverage rate is increased. Meanwhile, the device is simple in structure, convenient to produce and machine, low in cost and suitable for being used and popularized.

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...
