Drawings
FIG. 1 is a schematic front view of the present invention;
FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1;
in the figure: 1. the special lathe comprises a special bedplate, 2 fan-shaped clamping plates, 3 screws, 4 conical positioning pins, 5 mandrels, 6 nuts, 7 workpieces, 8 lathe bedplates.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
In the figure: vertical lathe special workstation, including lathe platen 8, screw 3, its characterized in that: the lathe bedplate 8 is connected with the special bedplate 1 through a plurality of screws 3, and the lathe bedplate 8 and the special bedplate 1 are also provided with conical positioning pins 4; a central hole of the special bedplate 1 is internally provided with a mandrel 5, the working surface of the special bedplate 1 is provided with a workpiece 7, and a plurality of fan-shaped clamping plates 2 are arranged in the hole of the workpiece 7; the mandrel 5 passes through the special bedplate 1 and the fan-shaped clamping plate 2 and is fastened through a nut 6. The special bedplate 1 is provided with a positioning round table matched with an inner hole of the lathe bedplate 8. The nut 6 is of a nut and washer integrated structure, and the bottom plane of the washer is perpendicular to the center of the nut. The matching part of the mandrel 5 and the fan-shaped clamping plate 2 is provided with a conical surface, and the upper part of the conical surface of the mandrel 5 is small in size and the lower part of the conical surface is large in size. The outer ring of the fan-shaped clamping plate 2 is small in thickness, the inner ring of the fan-shaped clamping plate 2 is large in thickness, the bottom surface of the fan-shaped clamping plate 2 is perpendicular to the excircle, and the inner hole of the fan-shaped clamping plate 2 is coaxial with the excircle; fan-shaped splint 2 is provided with hollow structure, and hollow department is provided with a plurality of strengthening rib between fan-shaped splint 2 inner circle and the outer lane, and fan-shaped splint 2 is provided with the circular conical surface with 5 cooperation departments of dabber, 2 hole circular conical surfaces upper portion sizes of fan-shaped splint are big, and the lower part size is little.
When the special bedplate is installed, the positioning round platform of the special bedplate is installed in the center hole of the lathe bedplate, the coaxiality of the special bedplate and the lathe bedplate is ensured, the mandrel is installed in the special bedplate hole, the coaxiality of the mandrel and the special bedplate is ensured, and the nut is screwed in.
