Abstract: A flexible/adjustable fixing system (100) for fixing a workpiece (40) includes an information management module (10), a plurality of driving devices (20), and a positioning device (30). The information management module receives and processes the position information of the workpiece. The driving devices electronically couple with the information management module. The positioning device includes a platform (31) and a plurality of positioning pins (32). One end of the workpiece is positioned in a certain area of the platform. Each respective pin is attached to a corresponding driving device. When the driving device receives an order/signal from the information management module, the positioning pin is selectably driven relative to (e.g., toward, away from) the workpiece by the driving device.

Abstract: An exemplary testing mechanism (100) is used for testing for a sufficiency of a casing 90. The testing mechanism includes a framework (20) and a testing module (40). The framework includes a base board (21) and a pillar (26). One end of the pillar is mounted on the base board. The testing module includes a main board (42) and at least one testing pin (44). The main board is slidably mounted on the pillar. A bottom end of the testing pin is slidably mounted to the main board. A top end of the testing pin is positioned adjacent to the base board of the framework. The at least one testing pin is located in a position corresponding to at least one mounting hole of a sufficient casing.

Abstract: A testing system for testing flatness of a surface of a workpiece includes a testing apparatus (10) and a processor (20). The testing apparatus includes a testing box (12) and a measuring apparatus (14). The testing box includes a plurality of holders (122); the holders define a datum plane. The measuring apparatus comprises a plurality of movable testing poles (142) extending out of the testing box and a plurality of gauges (141) configured for measuring distance of the testing poles retracting into the testing box. Ends (1421) of the testing poles away from the testing box are located at the datum plane and configured for supporting the surface of the workpiece thereon to allow the gauges measuring retracting distance of the testing poles under the pressure of the workpiece. The retracting distance of the testing poles is equal to distances between testing points on the surface of the workpieces and the datum plane.
