Abstract

The invention relates to the technical field of numerical control machine tools, in particular to a high-rigidity and high-precision dual-locking positioning device. The high-rigidity and high-precision dual-locking positioning device comprises a shell, a triple toothed disc, a friction plate contracting brake positioning device and a rotary shaft; the shell comprises a mounting seat, a connectingplate and an upper sealing plate; the mounting seat and the upper sealing plate are fixed to the two ends of the connecting plate correspondingly through bolts; the triple toothed disc comprises a floating toothed disc, a fixed toothed disc and a rotating toothed disc; and the friction plate contracting brake positioning device is composed of a rotating friction plate and a fixed friction plate and matched with a pneumatic / hydraulic device and a detecting device. The high-rigidity and high-precision dual-locking positioning device can conduct locking positioning at a fixed angle and can alsoconduct locking positioning at any position so as to complete complex hook face machining; and while the rigidity of contracting brake positioning is improved, the axial stress caused by axial movingof the rotating toothed disc during contracting brake positioning is eliminated, the positioning precision of the triple toothed disc is kept, the service life of the high-rigidity and high-precisiondual-locking positioning device is prolonged, and the high-rigidity and high-precision dual-locking positioning device is suitable for being popularized.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a high-rigidity and high-precision double locking positioning device. Background technique [0002] In the structure of the locking device of the existing heavy-duty CNC machine tool, most of the front-end end teeth are positioned, and the rear end is electronically braked. The positioning of the end-tooth plate positioning device is determined by the number of indexing teeth of the end-tooth plate, and it is impossible to achieve any position; or The electronic brake is used to achieve any position, but its rigidity is weak and the positioning accuracy is low, which cannot meet the needs of heavy-duty processing. Therefore, we propose a high-rigidity and high-precision double locking positioning device to solve the above problems. Contents of the invention [0003] The object of the present invention is to solve the shortcomings of existing locking devi...
