The utility model content
The purpose of this utility model provides a kind of machining tool of seat surface band arc structure needle-valve, it mainly is to solve the existing in prior technology process equipment can only be used for processing the needle-valve of common taper seat, and can't process the technical problem that seat surface has the needle-valve etc. of concave shaped cambered surface.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The machining tool of a kind of seat surface band arc structure needle-valve of the present utility model, comprise the anchor clamps that to locate needle-valve, anchor clamps are provided with the driving member that can drive the needle-valve rotation, it is characterized in that but described anchor clamps one end is provided with the emery wheel of abrasive point valve circle arc seat surface, grinding wheel diameter is 10～100mm, emery wheel be fixed on can be reciprocating bistrique on; Bistrique bottom is connected on the planker, and planker is connected with the drive unit that can make planker reciprocating, and planker, drive unit are located on the lathe bed; The axial line that is fixed on needle-valve axial line on the anchor clamps and bistrique is non-intersect, and the plane that is parallel to two axial lines is the perspective plane, and two axial line angle β of projection on this perspective plane are 10～170 °.Emery wheel of the present utility model is located on the lathe, and lathe is located at an end of anchor clamps anchor clamps.After needle-valve was lived in the location, needle-valve can rotate on anchor clamps and can not deviate from.Driving member can be driven by drive motors, makes it can drive the needle-valve rotation.The axial line of needle-valve axial line and bistrique with the plane of two axle center line parallels on projection form angle β, can guarantee emery wheel can be on the seat surface of needle-valve grinding go out the cambered surface of concave shaped.Planker can be led on the rule reciprocating at bed piece, thereby makes emery wheel axially also move back and forth.As anchor clamps is not horizontal positioned, and is tilt to place, the plane of the axial line formation angle β of needle-valve axial line and the bistrique angle that yet correspondingly tilts.
As preferably, describedly be positioned in needle-valve axial line on the anchor clamps and axial line angle α of projection on horizontal plane of bistrique is 20～50 °.The seat surface of needle-valve is generally 60 °, and therefore, angle [alpha] generally can be about 30 °, specifically decides with the relative height of C.G. of needle-valve seat surface according to the emery wheel center line.
As preferably, described drive unit is reciprocating oil cylinder or cylinder.
As preferably, described anchor clamps are for locating " V " type keeper of needle-valve guiding cylindrical.
As preferably, described driving member is a drive, and the outer surface of drive is coated with the flexible material layer.The flexible material layer can guarantee that promptly needle-valve can rotate, and can prevent its wearing and tearing needle-valve again under it drives.
Therefore, the utlity model has and to process the needle-valve that seat surface has the concave shaped cambered surface, characteristics such as simple and reasonable for structure.
