The invention belongs to the technical field of machine tool fixtures, and relates to a boring fixture for processing two space intersection holes on a special-shaped part. The problem is solved thatin an existing processing method, the use amount of boring fixtures is large, the positioning error is large and the dimensional accuracy between the two holes is difficult to ensure. The fixture includes a bottom plate, an XY planar moving plate, a YZ planar fixing plate, an X-direction rotating shaft, a YZ planar moving plate, a connector, a first positioning shaft, a first support component, asecond positioning shaft, a second support component and an auxiliary measuring pin. The XY planar moving plate is parallel and hinged to the bottom plate, the YZ planar fixing plate is perpendicularto and fixedly connected with the XY planar moving plate, the X-direction rotating shaft is perpendicular to the YZ planar fixing plate and can rotate around the YZ planar fixing plate, the YZ planarmoving plate and the connector are fixedly connected with the X-direction rotating shaft and located on the two sides of the YZ planar fixing plate respectively, the first positioning shaft is coaxialwith the X-direction rotating shaft and used for clamping one end of the special-shaped part, the first support component is used for making the first positioning shaft is fixedly connected with theXY planar moving plate, the second positioning shaft is used for clamping the other end of the special-shaped part, and the second support component and the auxiliary measuring pin are fixedly connected with the connector. The invention further provides a processing method for the two space intersection holes on the special-shaped part through the boring fixture.
Description
technical field [0001] The invention belongs to the technical field of machine tool fixtures, and in particular relates to a boring fixture and a processing method for machining two spaces intersecting holes on special-shaped parts. Background technique [0002] Such as figure 1 The shown special-shaped part 1900 to be processed has a large external dimension (about 1.5 meters long) and irregular shape, and has a first positioning hole 1906 and two coaxial first holes 1901 to be processed (Ф60H7 bushing hole), and the first positioning hole 1906 intersects and is perpendicular to the axis of the first hole to be processed 1901 (Ф60H7 bushing hole), the first positioning hole 1906 includes a coaxial first positioning small hole 1904 and a first positioning large hole 1903, And the first positioning large hole 1903 is provided with threads; the other end has a second hole to be processed 1902 (Ф50H8 bushing hole) and two coaxial second positioning holes 1905, the second posit...
