Problems solved by technology
The defects of this type are: for the processing of curved parts, multiple sets of fixtures are required for multiple clamping to complete the processing, because the processing of curved parts is difficult, and the use of traditional fixtures requires a little bit of clamping, which is cumbersome and time-consuming. When clamping, it is easy to cause deformation of the workpiece, it is not easy to locate, the deviation of the processing size is large, it is very unstable, and it affects the processing accuracy

The invention discloses a clamp special for machining of a cylindrical face hole. The clamp comprises a clamp main board. The clamp main board is integrally a cuboid. The upper surface of the clamp main board is a machining datum plane. A fixing unit is arranged on the datum plane and comprises a pressing plate which is fixed to the clamp main plate through an M8 locking screw. The clamp is recessed downwards at the middle position of the machining datum plane to form a first positioning groove which is through in the front-and-back direction, and meanwhile the edge of the rear side of the machining datum plane is recessed downwards to form an auxiliary fixing groove matched with the first positioning groove. By means of the clamp, the integral design and positioning manner of the clamp is adjusted, deformability of a workpiece is controlled, a spring is used for torsional clamping and fixing of the workpiece, the phenomenon that the location degree of the hole is not good in the product machining process is avoided due to double fixing in the two directions, the difficulty that clamping is difficult is well overcome, and the production efficiency is greatly improved.
Description
technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a special fixture and a clamping method for CNC machining a cylindrical surface. Background technique [0002] The earlier fixture type is mainly composed of moving jaws and fixed jaws, and the type is relatively simple. The defects of this type are: for the processing of curved parts, multiple sets of fixtures are required for multiple clamping to complete the processing, because the processing of curved parts is difficult, and the use of traditional fixtures requires a little bit of clamping, which is cumbersome and time-consuming. When clamping, it is easy to cause deformation of the workpiece, it is not easy to locate, the deviation of the processing size is large, it is very unstable, and it affects the processing accuracy. Contents of the invention [0003] The invention aims to provide a special fixture and clamping method for machining cylindrical surface holes ...
