Abstract

The invention relates to the mechanical field, in particular to a shaft distance calibrating method. The method comprises the following steps that 1, a drilling shaft or a threading shaft of a drilling-threading machine is selected as a coordinate reference shaft, and machining files of three holes are written, wherein the machine coordinate of the first hole is (0,0), any X and Y machine coordinate of the second hole accords with the corresponding coordinate of the first hole, and the machine coordinate of the third hole is an any value; 2, the first hole and the second hole are machined on a circuit board through a reference shaft of the drilling-threading machine, and the third hole in machined on the circuit board through the other shaft; 3, the actual coordinate value of the third hole in the circuit board is detected through quadratic element detection equipment; and 4, according to the difference value between the machine coordinate of the third hole and the actual coordinate, the shaft distance between the two shafts of the drilling-threading machine is calculated. The shaft distance calibrating method is easy and practical, the machining precision problem caused by deformation caused by thermal expansion of workpieces and a mechanical structure is solved, and equipment machining performance is improved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a method for calibrating the distance between axes. Background technique [0002] Since circuit board manufacturers need proofing, proofing requires the use of drilling rigs and gong machines for drilling and forming respectively. In order to save time for proofing, a dual-purpose drilling and gong machine that can complete drilling and forming on the same machine came into being. The use of drilling and gong dual-purpose machines for proofing can not only reduce the time for panel installation, disassembly and repositioning, but also save equipment investment. [0003] figure 1 It is a schematic diagram of the structure of the drilling and gong dual-purpose machine. Its main body adopts a gantry structure, and the X and Y axes are separated and independent. The drill shaft and the gong shaft are installed in the X-axis direction; Driven by a motor, the positions of the two axes are pro...
