Description

technical field

The utility model relates to an instrument for detecting the height of conductive metal plate objects, in particular to a metal plate height detector with simple structure, convenient use and improved detection speed.

Background technique

At present, in actual production, many metal parts 18 are punched with many small shrapnel 18' for connection or limit assembly (as shown in Figure 1), and the height H ejected by these shrapnel 18' generally requires accuracy Not too high, but must be controlled. For the measurement of the height H of the shrapnel 18', if a caliper is used to measure, since the shrapnel 18' is relatively soft, it will deform after being pressed, and it is difficult to grasp when it is just in contact without deformation, and the measurement error is relatively large. It is naturally more accurate to measure with a projector, but many parts such as the keymat steel sheet are deformed, so they need to be leveled before testing, so it is necessary to make a special measuring fixture to measure after leveling, which takes a long time. And the projector needs to be operated by a special person, which is difficult to popularize. Especially when the product needs to be inspected in large quantities, the efficiency of the projector is too low.
