This utility model provides a
machining center fixture, belonging to the field of
machining center technology, including a mounting plate; a base, which is fixedly mounted on the upper surface of the mounting plate, and the base has a positioning groove for positioning the workpiece; the base has several locking structures for fixing the workpiece on its side, the locking structure including a telescopic structure fixedly mounted on the mounting plate, and a locking block is hinged to the output shaft of the telescopic structure; this utility model, by setting a
telescopic cylinder, locking block and connecting rod, can lock the workpiece while providing clearance for the
machining tool, eliminating the need for separate machining of the workpiece edge, thus improving the machining efficiency of such parts; in addition, this fixture is made by sand mold 3D printing process, which is not only easy to process, but also saves the part
processing time and
assembly time of the fixture, and produces less waste, reducing the manufacturing cost of the fixture.
