Embodiment Construction
[0025] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] Such as figure 1 As shown, it is a flow chart of a method for positioning the workpiece center of a CNC boring and milling machining center, including:
[0027] Step 101, obtaining the workpiece center in the X-axis workpiece zero point offset value, the Z-axis workpiece zero point offset value and the V-axis workpiece zero point offset value;
[0028] Step 102, calculating the first angle value between the workpiece center and the coordinates;
[0029] Step 103, obtaining the length of the right-angle head corresponding to the attachment type;
[0030] Step 104, according to the length of the right-angle head, the Z-axis workpiece zero offset value and the V-axis workpiece zero offset value, determine the positive and ne...

The invention relates to the field of boring and milling processing, and discloses a method and device for locating the workpiece center of a numerically controlled boring and milling machining center. Zero point offset value; calculate the first angle value between the workpiece center and coordinates; obtain the length of the right-angle head corresponding to the attachment type; judge the center of the workpiece according to the length of the right-angle head, the Z-axis workpiece zero point offset value and the V-axis workpiece zero point offset value In the positive and negative direction of the center of rotation of the worktable; according to the positive and negative direction of the center of the workpiece circle in the positive and negative direction of the center of rotation of the worktable, calculate the angle value of the workpiece turning; according to the angle value, calculate the incremental offset value of the X axis and the incremental value of the Z axis offset value. The invention realizes that the workpiece is directly placed on the workbench for processing without alignment, which saves alignment time, reduces labor intensity of workers' operation, and improves processing efficiency.
Description
technical field [0001] The invention relates to the field of boring and milling processing, in particular to a method and a device for locating the workpiece center of a numerically controlled boring and milling machining center. Background technique [0002] The CNC boring and milling machining center machine tool is equipped with a rotary table with X, Y, and Z axes. The B axis is a rotary table. The center of the workpiece circle and the center regulator of the worktable are adjusted to be consistent before processing can be carried out. In the processing and manufacturing of the pump body of the shielded main pump, since there is a connecting pipe on the outer diameter, turning can not be performed on the CNC vertical lathe according to the turning circle, and the workpiece can only be placed in the center of the worktable in the CNC boring and milling process. Rotate the worktable to mill the outer circle of the workpiece, and can mill the fan-shaped outer circle part ...
