The invention discloses a modular fixture capable of guaranteeing angles of inclined planes and precision of inclined holes during CNN processing. The modular fixture comprises a fixture A, a fixture B and a fixture C, wherein the fixture A is provided with a fixture main board; the integral fixture main board adopts a cuboid; the middle part of the rear side face of the fixture main board bulges backwards to form a boss; a left fixing unit comprises a first locating plate and a first fixing plate; a right fixing unit comprises a second locating plate and a second fixing plate; the fixture B is provided with a fixture main board which is a pentagon when seen from up to down; two set screws which vertically penetrate through the fixture main board are arranged on the fixture main board; a left locating unit and a right locating unit are respectively arranged in the positions, near the inclined planes, of the upper surface of the fixture main board; and the fixture C has the structure which is the same as that of the fixture B except that the fixture main body of the fixture C is a right trapezoid when seen from up to down. According to the invention, the integral design and location way of the fixture are adjusted, the three fixtures are adopted to form the modular fixture, a step-by-step machining precision method is adopted, margin is left for processing, the deformability of workpieces is controlled, and the processing precision and production efficiency are improved.
Description
technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a combined fixture and a clamping method for machining inclined holes on inclined planes by CNC. Background technique [0002] The earlier fixture type is mainly composed of two movable jaws and fixed jaws, and the type is relatively simple. The defects of this type are: it is easy to cause deformation of the workpiece hole during processing, it is difficult to locate, and affects the processing accuracy. It is difficult to ensure the angle of the workpiece slope and the accuracy of the inclined hole during processing. Separate processing increases the loading and unloading time of personnel and affects the processing time of products. Contents of the invention [0003] The invention aims to provide a combined fixture and a clamping method for CNC machining inclined-plane inclined holes to ensure the verticality, coaxiality and cylindricity of products. [0004] In ord...
