Description

Technical Field

[0001] The utility model belongs to the technical field of CNC machining, and particularly relates to a five-axis suction cup fixture for CNC machining of large and complex double-sided cavities. Background Art

[0002] Since large and complex double-sided cavity parts are too large and have a complex structure, five-axis linkage machining is required. When performing five-axis finish machining, traditional clamping methods have a large interference with the machine tool, and traditional clamping requires process stock removal, which is not conducive to roughing of parts with a large material removal rate, the development of machining programs, and the layout of part processes. In addition, traditional suction cups are not suitable for irregular and complex parts, and large suction cups may cause unstable machining due to insufficient air volume, and there is also a problem that the air passing holes of large suction cup fixtures are difficult to machine. Content of the Utility Model

[0003] In view of the above problems, the utility model provides a five-axis suction cup fixture for CNC machining of large and complex double-sided cavities.

[0004] To achieve the above object, the utility model adopts the following technical solutions:

[0005] A five-axis suction cup fixture for CNC machining of large and complex double-sided cavities includes an upper fixture body and a lower fixture body stacked up and down. An air passing groove is opened on the upper end surface of the lower fixture body, and at least one air passing hole is opened on the outer peripheral side wall of the lower fixture body. The air passing hole is communicated with the air passing groove.

[0006] Further, a trachea joint is arranged in the air passing hole.

[0007] Further, the shape of the air passing groove is an irregular shape.

[0008] Further, a lower fixture body sealing ring is arranged between the lower fixture body and the upper fixture body. The shape of the lower fixture body sealing ring is the same as that of the air passing groove, and the lower fixture body sealing ring is placed above the air passing groove.

[0009] Further, a plurality of positioning holes are oppositely arranged on the lower end surface of the upper fixture body and the upper end surface of the lower fixture body. The upper fixture body and the lower fixture body are positioned and connected by positioning pins inserted into the positioning holes.

[0010] Further, the upper fixture body and the lower fixture body are connected by a plurality of bolts.

[0011] Further, the five-axis suction cup fixture further includes a fixture quick-change plate. The fixture quick-change plate is located below the lower fixture body and is connected to the lower fixture body by bolts. A plurality of zero-point quick-change pull studs are arranged on the lower end surface of the fixture quick-change plate.

[0012] Furthermore, the five-axis suction cup fixture further includes a fixture foaming sealing ring, and the fixture foaming sealing ring is connected to the upper end surface of the upper fixture body.

[0013] The five-axis suction cup fixture for CNC machining of large and complex double-sided cavities of the present utility model adopts the design of upper and lower fixture bodies. An air passage groove is machined between the two fixtures to solve the problem of insufficient air volume and the need not to machine overly deep air holes. The use of upper and lower bodies can increase the height of the fixture to avoid machine tool interference, and the hidden air passage groove can machine the air holes of multiple cavities. The design of the upper and lower fixture bodies increases the height of the fixture to avoid machine tool interference, is suitable for the machining of various large double-sided cavities with multiple cavities, and improves production efficiency and machining stability.
