The reference block of vertical machining centre anchor clamps
Technical field
The utility model relates to a kind of reference block, especially a kind of reference block that is mainly used in the vertical machining centre anchor clamps.
Background technology
At present, the reference block of general vertical machining centre anchor clamps comprises compositions such as matrix, benchmark main aperture, cylinder straight hole and step straight hole, when producing in enormous quantities, a large amount of cooling fluids and smear metal are arranged under machining status, because each workpiece of changing, lathe all will be found accurately once this initial point, and this cooling fluid and smear metal removing, the discharging on reference block is convenient inadequately, also can reduce and find precision and working (machining) efficiency accurately.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of reference block of vertical machining centre anchor clamps is provided, utilize this reference block after, the discharging of cooling fluid and smear metal is more convenient quick, can enhance productivity effectively, improve and find precision accurately.
The technical scheme that provides according to the utility model, the reference block of described vertical machining centre anchor clamps, comprise the matrix that being of vertical setting is cube-shaped, on matrix, offer the benchmark main aperture that runs through its top end face and bottom face, the axis of described benchmark main aperture and matrix are in the central lines of vertical direction, benchmark main aperture bilateral symmetry position at the top end face of matrix offers cylinder straight hole and step straight hole, wherein, the axis of cylinder straight hole is parallel with the axis of benchmark main aperture, offer letdown tank at the matrix bottom face, described letdown tank is communicated with the bottom of benchmark main aperture.
The top ends of described benchmark main aperture is provided with the outreach part.Described step straight hole is formed by the different cylindrical hole stack of two-section internal diameter up and down, and the cylindrical hole diameter that is positioned at the top is greater than the cylindrical hole below being positioned at.Described letdown tank comprises and is transverse groove and the cannelure that intersects vertically that transverse groove is consistent with the cannelure width, and the axis of benchmark main aperture passes the center of transverse groove and cannelure cross-shaped portion.Arris at the vertical direction of matrix is provided with chamfering.
The utility model is after installing and using, and the discharging of cooling fluid and smear metal is more convenient quick, can enhance productivity effectively, improves and finds precision accurately.

The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: it comprises that vertical setting is cube-shaped matrix 1, on matrix 1, offer the benchmark main aperture 2 that runs through its top end face and bottom face, the axis of described benchmark main aperture 2 and matrix 1 are in the central lines of vertical direction, offer cylinder straight hole 3 and step straight hole 4 in the benchmark main aperture 2 bilateral symmetry positions of the top end face of matrix 1, wherein, the axis of cylinder straight hole 3 is parallel with the axis of benchmark main aperture 2, offer letdown tank 5 at matrix 1 bottom face, described letdown tank 5 is communicated with the bottom of benchmark main aperture 2.
The top ends of described benchmark main aperture 2 is provided with outreach part 6.Described step straight hole 4 is formed by the different cylindrical hole stack of two-section internal diameter up and down, and the cylindrical hole diameter that is positioned at the top is greater than the cylindrical hole below being positioned at.Described letdown tank 5 comprises and is transverse groove and the cannelure that intersects vertically that transverse groove is consistent with the cannelure width, and the axis of benchmark main aperture 2 passes the center of transverse groove and cannelure cross-shaped portion.Arris at the vertical direction of matrix 1 is provided with chamfering 7.
The utility model is mainly used in the vertical machining centre anchor clamps, and the intersection of the axis of benchmark main aperture 2 and matrix 1 top end face has been represented the initial point of anchor clamps, and the location benchmark of workpiece all is to mark with this initial point with respect to the position of anchor clamps.Anchor clamps all will adopt this initial point to find accurately with respect to the position of lathe.Owing to offer letdown tank 5 at matrix 1 bottom face, made things convenient for removing, the discharging of cooling fluid and smear metal, avoided the interference of cooling fluid and smear metal in finding position fixing process accurately, improved production efficiency.
