Abstract
The invention provides a lathe structure for a replaceable station. Two pipe heads on the same axis can be positioned on the same clamp so as to ensure the displacement and coaxiality between the pipe heads. The lathe structure comprises a longitudinal flange plate and a bottom plate, wherein one side of the flange plate is connected with a lathe spindle; and the bottom plate is tightly connected with the other side of the longitudinal flange plate. The lathe structure is characterized in that an annular positioning plate is supported in the bottom plate, a central hole is formed in the centre of the annular positioning plate; the bottom of a positioning column is sleeved in the central hole; a screw penetrates through the annular positioning plate and then is tightly connected with the positioning column; after parts to be processed are sleeved in the positioning column, a press nut penetrates through the bottom plate and then is connected with the lower end of the positioning column; an upper pressure plate is pressed on the upper end surface of the positioning column; an upper lock nut penetrates through the upper pressure plate and is then tightly connected with the upper end of the positioning column; two pipe heads of the parts to be processed are respectively located on the straight line of the lathe spindle; and the press nut is pressed in the connection plate.
Description
Technical field
The present invention relates to the location structure technical field of workpiece, be specially a kind of station that changes and use lathe structure.
Background technology
The turning of prior art is used with single station with anchor clamps only; I.e. turning processing can only be processed coaxial cylindrical or endoporus; And but these cylindricals and endoporus must be in the general turning cutting tool range of work, can not be long like hole depth greater than cutter, and the aperture can not be less than knife bar diameter etc.All want the part of Vehicle Processing for having a plurality of tube heads so; Separately each tube head is processed with regard to needing operation break-down; Part will be through repeatedly dismantling clamping like this, and each clamping all can produce position error, makes that position degree and the axiality between the tube head is difficult to guarantee.
Summary of the invention
To the problems referred to above, the invention provides a kind of station that changes and use lathe structure, it makes two tube heads on the same axis on same anchor clamps, to position, and guarantees position degree and axiality between the tube head.
A kind of station that changes is used lathe structure, and its technical scheme is such: it comprises longitudinal flange dish, base plate, and said ring flange one side connects lathe spindle; Said base plate is fastenedly connected said longitudinal flange dish opposite side; It is characterized in that: the circular orientation plate is supported on said base plate, and the center of said circular orientation plate has centre bore, and the bottom of reference column is set in the said centre bore; Screw is fastenedly connected said reference column after running through said circular orientation plate; After part to be processed was set in said reference column, clamp nut ran through the lower end that connects said reference column behind the said base plate, and top board press-fits the upper surface in said reference column; Upper locking nut runs through the upper end that is fastenedly connected said reference column behind the said top board; Two tube heads of said part to be processed lay respectively on the lathe spindle straight line, and said clamp nut press-fits in connecting plate, and pin runs through the lower surface that is fastenedly connected said base plate behind the said connecting plate.
After adopting the present invention, after the preceding tube head that is positioned at lathe spindle processes, unclamp locking nut, upper locking nut; Unload top board successively, with part to be processed, reference column, location-plate three Rotate 180 °, tighten clamp nut afterwards then; Load onto top board, tighten upper locking nut, lathe spindle is processed the back tube head; Since through above the same secondary frock station conversion, realize the processing of two tube heads, and the base plate maintenance is motionless; It makes two tube heads on the same axis on same anchor clamps, to position, and guarantees position degree and axiality between the tube head.
Description of drawings
Fig. 1 is a cutaway view structural representation of the present invention;
Fig. 2 is the cutaway view structural representation behind the part Rotate 180 °.
The specific embodiment
See Fig. 1, Fig. 2, it comprises longitudinal flange dish 1, base plate 2, and ring flange 1 one sides connect lathe spindle; Base plate 2 is fastenedly connected longitudinal flange dish 1 opposite side, and circular orientation plate 4 is supported on base plate 2, and the center of circular orientation plate 4 has centre bore 5; The bottom of reference column 6 is set in the centre bore 5, and screw 7 is fastenedly connected reference column 6 after running through circular orientation plate 4, after part 14 to be processed is set in reference column 6; Clamp nut 8 runs through the lower end of connecting plate 12, base plate 2 back connection reference columns 6; Top board 9 press-fits in the upper surface of reference column 6, and upper locking nut 10 runs through the upper end that is fastenedly connected reference column 6 behind the top board 9, and two tube heads 3,11 of part 14 to be processed lay respectively on the lathe spindle straight line; Clamp nut 8 press-fits in connecting plate 12, and pin 13 runs through the lower surface that is fastenedly connected base plate 2 behind the connecting plate 12.
Claims (1)
1. one kind can be changed station and uses lathe structure, and it comprises longitudinal flange dish, base plate, and said ring flange one side connects lathe spindle; Said base plate is fastenedly connected said longitudinal flange dish opposite side; It is characterized in that: the circular orientation plate is supported on said base plate, and the center of said circular orientation plate has centre bore, and the bottom of reference column is set in the said centre bore; Screw is fastenedly connected said reference column after running through said circular orientation plate; After part to be processed was set in said reference column, clamp nut ran through the lower end that connects said reference column behind the said base plate, and top board press-fits the upper surface in said reference column; Upper locking nut runs through the upper end that is fastenedly connected said reference column behind the said top board; Two tube heads of said part to be processed lay respectively on the lathe spindle straight line, and said clamp nut press-fits in connecting plate, and pin runs through the lower surface that is fastenedly connected said base plate behind the said connecting plate.
