How does the checking fixture work?

test fixtures

Checking fixture is a tool used to detect the size, shape, position, surface quality and other parameters of part. The principle is to measure the gap, height and other parameters between the parts and the gage, to determine the part size, shape position and other information.

  • First, the gage needs to position the part in the correct position.This can be achieved by adjusting the ending tightening device.Once the part is correctly positioned the gage is ready to be measured
  • Second, the gage measures parameters such as the gap living height difference between the part and the gage.This can be achieved by using tools such as micrometers, vernier calipers, stoppers, etc.According to measurement.Can determine the size of the part shape position and other information.
  • Finally, the measuring structure is analyzed and evaluated

If the measurement results meet the requirements, it means that the part is qualified. Otherwise, the parts need to be corrected or replaced. In general, the working principle of the gage is By measuring the gap height difference between the parts and the gage and other parameters. To determine the part size, shape position and other information. This technique is widely used in manufacturing. It can improve product quality and production efficiency.
