Description

Technical Field

[0001] The utility model belongs to the technical field of slot milling of milling machines, and more specifically relates to a slot milling fixture for a numerically controlled milling machine. Background Art

[0002] CNC milling machines can accurately perform slot milling under the control of program codes. They use rotating tools to cut one or more slot structures with specific shapes and sizes on the surface of the workpiece. When using CNC milling machines to process slots, a CNC milling slot milling fixture is required to fix the parts. The existing CNC milling slot milling fixtures are mainly composed of a driving structure, a clamping structure and a positioning structure. The positioning structure ensures that the initial position of the workpiece before processing is accurate. The driving structure is mostly a pneumatic or electric push rod, which uses the push rod to drive the clamping structure to clamp the parts.

[0003] The existing utility model patent with application number 202322586625.8 discloses a milling machine fixture and a milling machine, including a mounting seat, an angle adjustment assembly is provided on the mounting seat, the angle adjustment assembly includes a support seat installed on the mounting seat, a spherical groove is provided in the support seat, a groove is provided on the inner wall of the spherical groove, a rotating ball is provided in the spherical groove, a column is provided at the upper end of the rotating ball, a vise clamp is provided on the column, and the vise clamp includes a support plate provided on the column; this application uses the angle adjustment assembly, the vise clamp, and the level in combination, and by twisting the screw, the fixed block is moved away from the rotating ball, and the extrusion lock on the rotating ball is released, so that the support seat and the rotating ball form a ball hinge assembly, which can enable the vise clamp to rotate freely and adjust the angle in three-dimensional space, and can achieve a wider range of angle adjustment to meet the processing requirements of different workpieces.

[0004] Based on the above, the existing CNC milling machine slot milling fixture is not convenient for changing the angle position of the part after fixing the part. When it is necessary to mill slots on multiple sides of the part, every time a side of the part is processed, the staff needs to manually remove the part and change the side before clamping it to mill the slot. The part side changing operation steps are too cumbersome, which affects the efficiency of part slot milling. Utility Model Content
