Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] An integrated workbench for test calibration of an automatic hole-making system according to the present invention, the schematic diagram of which is shown in 1 and figure 2 As shown, it includes a column frame 4. The column frame 4 is divided into upper and lower layers. A partition is fixed in the middle of the upper layer. A visual camera calibration module 1 is placed on one side of the partition. The visual camera calibration module 1 includes a clamping assembly through bolts. 6 The alignment test plate 8 fixed between the side wall of the column frame 4 and the partition, the alignment nail 9 is fixed on the side of the surface of the alignment test plate 8, and the normal sensor calibration module is installed on the other side of the partition 2. The normal direction sensor calibration module 2 includes a standard flat panel ...

Abstract

The invention discloses a testing and calibration integrated working table for automatic hole making system. The table includes a column frame which is divided into an upper layer and a lower layer, the upper layer is divided into two blocks through a division plate, one side of the division plate is provided with a vision camera calibration block which includes an alignment test plate fixedly connected between the side wall of the column frame and the division plate, positioning nails are fixed on the alignment test plate, and the other side of the division plate is provided with a normal sensor calibration block which includes a standard surface plate installed in the groove of the inner side wall of the column frame and the division plate; and the lower layer area of the column frame isprovided with a hole-making technology test module. The invention also discloses a calibrated method for an automatic hole-making system test. Firstly, the distance between the vision camera axis andthe hole-making cutting tool axis of the automatic hole-making system is calibrated, then, the distance between the normal sensor and the front end surface of a pressure foot of the automatic hole-making system is calibrated, and finally the hole-making and measurement are performed on a hole-making test plate. The problem that the prior art does not have the calibration function of the measurement system and the system error compensation cannot be realized is solved.

Description

technical field [0001] The invention belongs to the technical field of advanced digital flexible processing and automation, and relates to an integrated test and calibration workbench for an automatic hole-making system and a calibration method. Background technique [0002] The automatic hole-making technology based on industrial robots and CNC machine tools is an advanced automation and digital manufacturing technology, which is of great significance to aircraft assembly and other industrial fields that require a large number of holes. In order to realize the digitalization, flexibility and intelligence of the automatic hole making system, the automatic hole making system is generally equipped with a normal sensor and a visual camera measurement system. The normal sensor is used to measure the normal direction of the working surface, and the vision camera measures and recognizes the positioning nails on the working surface to provide positioning information for the automat...
