Abstract

The present invention provides a projection measurement positioning device for positioning a plate-shaped workpiece to be projected. The positioning device includes a support plate, two blocking walls and a locking body arranged on one surface of the support plate. The blocking walls are parallel to each other and form a holding groove with the support plate. The locking body is arranged on the one blocking wall, and one side of the workpiece is accommodated in the holding groove. The surface of the workpiece is close to the blocking wall without the locking body and is locked by the locking body, and the other side of the workpiece is the position to be measured.

Description

technical field [0001] The invention relates to a projection measurement positioning device. Background technique [0002] It is very convenient to use projection to measure the appearance and size of the item. The projection measurement is to enlarge the electronic image of the item to be tested through an electron microscope and transmit it to the screen for detection, and judge the item to be tested by observing the image on the screen. Whether the size and surface structure meet the requirements. [0003] see figure 1 , in the prior art, the measurement of thin plate-shaped objects such as the lens 1 is to place the lens 1 flat on the platform 2, and the electron microscope 3 projects the front of the lens 1 directly above, and the chamfer 4 of the lens 1 is only a front image , it is impossible to observe the size and angle of chamfer 4, as well as the appearance and straight-up position on the chamfer. Contents of the invention [0004] The technical problem to be...
