Description

Technical Field

[0001] The utility model relates to the field of numerically controlled machine tools, in particular to a tool magazine installation and adjustment structure. Background Art

[0002] When the CNC machine tool calibrates the tool change point between the spindle and the tool magazine, in order to improve the positioning accuracy of the tool magazine and achieve the overall quality of the machine tool, the accuracy of the tool magazine installation of the machine tool must be strictly controlled and the tool magazine must be repeatedly installed and debugged. In addition, adjusting and maintaining the accuracy of the tool magazine is a basic indicator for measuring the accuracy of CNC machine tools. However, due to the weight of the tool magazine and the tool magazine mounting bracket, the debugging process of the tool magazine accuracy becomes complicated and difficult. Moreover, due to the weight of the tool magazine and the tool magazine mounting bracket itself, after the tool magazine accuracy is adjusted, the accuracy will change due to the center of gravity.

[0003] For example, Figure 1 A schematic diagram of a tool magazine installation and adjustment structure in the prior art is shown. Figure 1 As shown, the tool magazine mounting bracket 14 is mounted and fixed on the base 1; and the tool magazine 2 is connected to the tool magazine mounting bracket 14. When calibrating the tool change point of the tool magazine 2, a micrometer is used to be adsorbed on the surface of the workbench 15. It is necessary to adjust the tool magazine 2 and the tool magazine mounting bracket 14 so that the position of the tool magazine 2 and the workbench 15 are kept parallel. This operation is repeated to calibrate the tool change point when the spindle and the tool magazine 2 change tools.

[0004] However, during the measurement and calibration process, it is necessary to fine-tune the installation position of the tool magazine 2 and the tool magazine mounting bracket 14 for many times, and the tool magazine 2 and the tool magazine mounting bracket 14 are too heavy. When the manual installation position is used, it is easy to have insufficient adjustment and calibration or excessive adjustment of the installation position, and insufficient stability due to weight after fixing and locking. It takes too long, and the accuracy of the tool magazine calibration makes it difficult to achieve the expected effect. Utility Model Content
