SUMMERY OF THE UTILITY MODEL
The utility model aims at the prior art that the clamping is usually carried out through three claws, but when the thin-wall part is directly clamped, the three-claw clamping force is large, and the clamping fixed position is easy to be damaged and deformed; and the clamping processing can only be carried out singly during three-jaw clamping, which affects the processing efficiency and the yield, therefore, the following technical scheme is provided:
the utility model provides a special finish turning anchor clamps of ball iron lid inner wall, includes the location body, the location body is the cylinder structure, location body outside clamping is on the lathe three-jaw chuck, location body right-hand member is opened there is the side ear groove, it has the mounting groove to open in the middle of the side ear groove tank bottom, the mounting groove tank bottom runs through to open there is the hole of stepping down, the installation ball iron lid body of embedding in the mounting groove, the major diameter ring embedding of ball iron lid body right-hand member is in the side ear inslot, the side ear inslot evenly opens has a plurality of screw holes, the stay bolt is installed through the screw hole to location body left end, the stay bolt passes on the major diameter ring that the screw hole is connected to ball iron lid body right-hand member.
Preferably, the bottom of the mounting groove is provided with a support ring at the edge of the abdicating hole, and the right end face of the support ring is in contact with the left end face of the ball iron cover body.
Preferably, the inner diameter of the abdicating hole is larger than the aperture of the left end of the ductile iron cover body.
Preferably, the distance from the left end face of the ductile iron cover body to the left end of the large-diameter ring is matched with the depth of the mounting groove.
Preferably, the number of the threaded holes is at least 2, and at least 2 of the threaded holes are symmetrically arranged
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses simple structure, the clamping is convenient, and corresponds nodular iron cover rear end and inner wall structure and set up the dedicated anchor clamps body, fixes through the screw of nodular iron cover body side, makes location benchmark and nodular iron cover keep unanimous, guarantees the processingquality of nodular iron cover body, can be used to batch production, improves machining efficiency.

The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a cross-sectional view of an installation of an embodiment of the present invention;
fig. 2 is an exploded cross-sectional view of an embodiment of the present invention;
fig. 3 is a schematic structural diagram of an embodiment of the present invention;
the embodiment of the utility model provides a mainly contain following element symbol:
the positioning device comprises a positioning body-1, a side lug groove-2, a threaded hole-201, a mounting groove-3, a support ring-301, a abdicating hole-4, a long bolt-5, a ductile iron cover body-6 and a large-diameter ring-601.
Detailed Description
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
As shown in fig. 1 to 3, a special finish turning anchor clamps of ball iron lid inner wall, including location body 1, location body 1 is the cylinder structure, 1 outside clamping of location body is on the lathe three-jaw chuck, 1 right-hand member of location body opens there is side ear groove 2, it has mounting groove 3 to open in the middle of the 2 tank bottoms of side ear groove, 3 tank bottoms of mounting groove run through to open there is the hole of stepping down 4, embedding installation ball iron lid body 6 in the mounting groove 3, the major diameter ring 601 embedding of ball iron lid body 6 right-hand member is in side ear groove 2, evenly open in the side ear groove 2 has a plurality of screw holes 201, long bolt 5 is installed through screw hole 201 to location body 1 left end, long bolt 5 passes on the major diameter ring 601 that screw hole 201 is connected to ball iron lid body 6 right-hand member.
