Description
Technical Field
The utility model belongs to the field of length measurement, and particularly relates to a gauge block clamp for assembling groove width and height difference.
Background
The laser clearance gun is directed to an assembly size device on an aircraft with a complex profile and which is not easy to measure. The assembly sizes such as clearance, joint difference, angle radius and the like can be accurately measured. The calibration of the laser gap gun indication error requires a height difference and a slot width to be evaluated. And the calibration requirement is that the gauge blocks are combined into a height difference and a slot width as shown in fig. 1. The combined gauge block needs a special clamp to clamp the gauge block, so that the indication error of the laser gap gun can be accurately calibrated. In the prior art, calibration is carried out by a standard test block with fixed height difference and groove width provided by a manufacturer. The existing technical problem is that the laser gap gun has two measuring heads to be calibrated, and the measuring ranges of the two measuring heads are (0-15) mm and (0-40) mm respectively. Accurate calibration of the laser gap gun requires measuring height differences and slot widths of different sizes within its measurement range. The combination of the gauge blocks into a plurality of sizes of height differences and slot widths requires a dedicated gauge block fixture for clamping.
