It is best to ensure the parallelism between the centerline of the hole and the reference surface.

The measuring tool is closely attached to the measuring surface, and the distance between the two positions in the hole is measured respectively, and the minimum indication of the dial indicator is taken as the standard, and the parallel of the center line of the cold working measurement of the hole mechanic can also be measured. Degree, adjust the ram according to the test results until the parallelism is qualified. Then make a fine boring.

Measuring the distance from the centerline of the hole to the reference plane To ensure the dimensional accuracy of the line-to-face distance of the hole, the thickness is detected and the parallelism is detected, and the size is checked. The spindle position is adjusted based on the measured and calculated results and continuously measured during the roughing process until it is qualified.

Measuring the coaxiality of the hole core line As described above, since the ram is too long, the boring cannot be completed from one side at a time, and after the hole is finished, the table needs to be rotated. Therefore, it is a key problem to ensure the coaxiality of the center line of the two holes. At this time, the measurement is most suitable for using this self-made measuring tool.

First, the ram area is parallel to the main axis of the boring machine, and the actual distance from the center line of the hole to the surface is measured. Then, the surface of the boring machine is pressed against the measuring reference surface, and the prime line of the spindle of the boring machine is measured to calculate the dial indicator. Measure the distance from the point to the face (that is, the face of the gage) and adjust the spindle position until it is reached, which is the diameter of the spindle. In the same way, the distance from the centerline of the spindle to the face can also be adjusted.

After the hole is finished, the gauge is used to measure the coaxiality of the hole and the hole with the gauge as the reference. The self-made measuring surface is closely attached to the reference plane of the measuring chart, and is measured at two points near the hole end, and the two points and the distance dimension are respectively determined. The difference between the difference and the same method is measured on the surface and the concentricity error is calculated as: the concentricity error at the point is: the larger value is the concentricity error between the hole and the hole. If the measuring point cannot be taken at the end of the hole, the concentricity error can be converted proportionally.

This inspection tool measures the distance from the centerline of each hole to the reference plane and the parallelism between the centerline of the hole and the reference plane. The dimensions of the holder and base of the gauge can be made according to different part sizes, and various combinations can be made to complete the measurement. Since the bracket is made of stainless steel pipe, if it is too high, that is, the distance from the dial gauge to the surface is too large, it will affect the stability of the gauge. When using the gage, you must pay attention to the stability of the dial gauge. If the dial gauge is found to be vibrating, the measurement cannot be performed. The steel pipe with a larger diameter must be replaced, and the size of the base is increased accordingly to improve the accuracy of the measurement.
