Description
Technical Field
The invention belongs to the technical field of numerical control machine tools, and relates to a zero point recovery and calibration device for a machining center and a use method thereof, which are used for recovering the zero point of the machining center without arranging a zero return collision block and using an absolute encoder.
Background
For the zero point recovery of the machining center, the existing method takes an FANUC system absolute encoder machine tool as an example, and the zero point information of the machine tool is characterized by position data in an uninterruptible photoelectric encoder and a corresponding memory unit:
1. mechanical reference point return method: the method is that a return-to-zero collision block and a travel switch are arranged on a numerical control machining center, a machine tool main shaft returns to a machine tool reference point through the operation of returning the machine tool to the reference point, and the recovery of a machine tool coordinate system is completed by matching with the memory of the relevant pulse position information. The method has simple process and reliable functions, but the absolute encoder is adopted in the new machining center design to save cost and simplify the structure, so that the numerical control machine tool does not need to return to zero (i.e. return to a reference point) in most cases, and therefore, a plurality of devices do not maintain related structures, namely do not have the functions;
2. tool changing point-stroke recovery method: aligning the end part of the main shaft with the tool magazine tool changing position by using a plug gauge and an adjusting tool handle through a manual machine tool, recording the current Z position, and comparing the current Z position with a Z coordinate factory setting value to obtain the Z coordinate position of a machine tool zero point; x coordinate position determination: the manual machine tool is used for centering and determining the center surface of the T-shaped groove in the center of the workbench through the dial indicator and the drill chuck handle, and comparing the center surface with a set value of a factory X coordinate to obtain the X coordinate position of a machine tool zero point; coordinate position determination: and (3) operating the equipment to positive and negative hard limit by a manual machine tool, and calculating and approximately determining the Y-coordinate position of the zero point of the machine tool by a machine tool nominal stroke dividing method. The method has higher requirements on the Z-axis tool changing position alignment operation skills, usually requires after-sales service personnel of machine tool manufacturers to finish the operation, and has longer time consumption, and the Y-axis position determination error of the method is larger, so that the method only has the function of avoiding over travel. If the machine tool application enterprise uses the original machine tool zero point as a reference in the previous fixture setting process, the method needs to be aligned again after the zero point is restored.
3. The method for preprocessing the positioning holes on the workbench comprises the following steps: before the machine tool is used after leaving factory and checking, a position is selected on a machine tool workbench, a positioning hole and a positioning surface (a counter bore step surface) are machined in advance, then the mechanical coordinate positions of X and Y of a positioning hole core are recorded, the positions of the counter bore step surface and a mandrel with a steel ball inlaid on the end face are determined in a Z-direction machine tool coordinate system through a plug gauge, and a non-metal insert is inlaid in the machine tool workbench to protect a positioning reference hole and a positioning reference plane in working. When the coordinate system of the machine tool needs to be restored, the nonmetallic insert is taken out, the center position of the positioning hole is manually determined in a hole sweeping mode through the dial indicator, and the XY coordinate position of the zero point of the machine tool is restored according to the center position. And checking the counter bore step surface through a mandrel with a steel ball inlaid on the end surface and a plug gauge, so as to recover the Z coordinate zero point. The method has higher recovery precision, and the automatic zero point recovery function is easy to realize through the probe, but the new machine tool workbench is required to be perforated, and the method has negative effects on equipment precision and workbench surface strength.
