Problems solved by technology
[0003] During the operation, it is often necessary to check the drawings of the ejector pins while installing the ejector pins. In the installation of large parts, due to the large number of ejector pins to be installed, problems such as omission, overinstallation and offset of ejector pins are prone to occur, resulting in production failures. Various accidents occur from time to time, and the efficiency is low, which increases the time for mold installation; at the same time, the process drawings of the ejector pin will be dirty, and the storage of process data is not used.

The invention discloses a stamping production ejector rod hole fast positioning device and a stamping production ejector rod hole fast positioning method. The stamping production ejector rod hole fast positioning device comprises an ejector rod figure, an ejector rod figure recognition device and a positioning light beam emitting device, wherein the ejector rod figure recognition device comprises photosensitive sensors, a light source and a sealed box body, the photosensitive sensors and the light source are arranged in the box body, in addition, the photosensitive sensors are positioned right under the light source, the number and the distribution mode of the photosensitive sensors correspond to the number and the distribution mode of ejector rod holes formed in a machine tool tabletop, the positioning light beam emitting device comprises light beam emitters; light beam emitting sources with the number and the distribution mode corresponding to those of the ejector rod holes formed in the machine tool tabletop are arranged on the light beam emitters, the photosensitive sensors and the light beam emitters are in one-to-one correspondence matching, the ejector rod figure is a flat plate, and ejector rod installing hole positions with the number and the distribution mode corresponding to those of ejector rods of a drawing mold are formed in the ejector rod figure. The device and the method provided by the invention have the advantages that hole positions needing to be provided with the ejector rods can be fast recognized from numerous ejector rod holes of a machine tool, so that the ejector rod installing efficiency can be improved.
Description
technical field [0001] The invention relates to a rapid positioning device and method for ejector pin holes in stamping production. Background technique [0002] The traditional ejector installation method needs to use the positioning center of the machine tool table and the hole position of the edge ejector as the benchmark, and then calculate the installation position of each ejector according to the ejector map points, and then install the ejector. Each ejector during the ejector installation process The ejector pin must be checked with the ejector pin diagram at all times. [0003] During the operation, it is often necessary to install the ejector pin while checking the drawing of the ejector pin. In the installation of large parts, due to the large number of ejector pins to be installed, problems such as omission, overinstallation and offset of ejector pins are likely to occur, resulting in production failures. Various accidents occur from time to time, and the efficie...
