Description
Technical Field
The invention belongs to the technical field of machine tool components, and particularly relates to a calibration tool.
Background
The numerical control machine tool is a working master machine in equipment manufacturing industry, and the technical level of the numerical control machine tool represents the development level of national manufacturing industry. The machining center is the first member of the numerical control machine tool. The machining center reduces the time for clamping, measuring, adjusting a machine tool and the like of a workpiece due to the centralized and automatic tool changing of the working procedures, so that the cutting time of the machine tool reaches about 80 percent of the starting time of the machine tool (the common machine tool is only 15-20 percent); meanwhile, the turnover, transportation and storage time of workpieces among the working procedures is reduced, the production period is shortened, and the economic effect is obvious. With the continuous improvement of the requirements on high-precision parts, the machining precision is developed from millimeter level, micron level to submicron level or even nanometer level, and the machining quality of a workpiece can be seriously influenced by the misalignment of a cutter caused by clamping chips of a spindle in the high-precision machining process. The positions of the main shaft clamping scraps are mainly two positions: the taper plug is arranged in a gap between the upper surface of the cutter handle and the lower surface of the taper plug, and is arranged on a conical surface contacted with the cutter handle. In practical application, the following are found: the chip clamping faults generated at the two chip clamping positions are generated in the process of changing the cutter of the machining center. Therefore, in the process that the cutter handle is preassembled with the taper plug, the clamping scrap fault of the main shaft is detected and early warned, and the influence of the clamping scrap of the main shaft on the processing quality of parts is avoided. In recent years, more and more enterprises pay attention to the research and development and application of the chip clamping detection device, and the applicant is dedicated to the research in the field, and two granted Chinese patent application numbers 201815865483 and 2019112895034 are successively applied to the chip clamping detection device and obtained.
There is a continuing technical gap in the design and use of debris detection device calibration tools. At present, no special calibration tool exists in the production process. The chip clamping detection device can only be arranged at the tail end of the central spindle of the processing center, and the traditional broach mechanism is used for carrying out tool feeding operation, so that the chip clamping detection device is calibrated. Although the calibration method has high reliability, the step of installing the tool holder detection device on the electric spindle is complicated, the consumed time is long, the electric spindle of a machining center for production is occupied, and the production cost of the chip clamping detection device is indirectly increased. In this context, the calibration tool and the calibration method are designed to solve the problems existing at present.
