The invention relates to an electric fixture for workpiece machining and detection, and belongs to the technical field of work fixtures for machining. A clamping mechanism is installed on a base, anda platform is installed on the base through brackets; a locking mechanism is fixed to the platform, and a controller is fixed to the platform; and a measuring device is fixed to the position, close tothe controller, of the platform, and an anti-collision detection device is fixed to the position, close to the edge of the platform, of the side of a stop block I. The electric fixture has the advantages that the stop blocks are driven by a single motor through transmission of a bevel gear and a screw rod to slide along guide rails in the X direction and Y direction simultaneously and synchronously, and workpiece clamping is achieved quickly; the working efficiency is improved, and the labor intensity is reduced; the integration of machining and detection is achieved; not only is a lot of time for clamping and detection saved, but also special detection personnel and tools can be reduced, so that the workpiece manufacturing cost is saved greatly.
