Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 to 4: a tailstock convenient to adjust comprises a tailstock body 1, wherein the bottom of the tailstock body 1 is fixedly connected with a plurality of pairs of sliding blocks 2 through connecting bolts 17, the sliding blocks 2 are connected on sliding rails 3 in a sliding mode, a tailstock sleeve 4 is arranged at the top of the tailstock body 1, a tip sleeve 5 is connected in an inner cavity of the tailstock sleeve 4 in a sliding mode, a live tip 6 is inserted at the front end of the tip sleeve 5 in an inserting mode,
an eccentric rotating shaft 7 is rotatably connected in the side wall of the tailstock sleeve 4, a disc spring 8 is sleeved at the top of the eccentric rotating shaft 7, the disc spring 8 is positioned between a flange plate 9 and a limiting step 10 arranged on the eccentric rotating shaft 7, the flange plate 9 is fixedly connected on the tailstock sleeve 4 through a bolt, an inner hexagonal hole 11 is further formed in the center of the top end face of the eccentric rotating shaft 7, a pulley 12 is arranged at the bottom end of the eccentric rotating shaft 7, an elongated slot 13 is formed in the tip sleeve 5, the pulley 12 is slidably connected in the elongated slot 13, and the width of the pulley 12 is equal to that of the elongated slot 13,
the section of the center sleeve 5 is annular, the inner circle of the annular is an eccentric circle,
the bottom end face of the tailstock body 1 is further connected with a supporting plate 14 through a bolt, a horizontal adjusting gasket 15 is supported on the top end face of the supporting plate 14, one side of the horizontal adjusting gasket 15 is in contact with one sliding block 2, and the other part of the horizontal adjusting gasket is in contact with a vertical reference surface 16 on the tailstock body 1.
The utility model discloses the convenient tailstock's of adjustment working process as follows: when a certain bar workpiece needs to be machined, a chuck of a machine tool spindle clamps one end of the workpiece, and a live center 6 props against the other end of the workpiece; the action that the live center 6 props against the workpiece is realized by a hydraulic system arranged in the tail part of the center sleeve 5; thus, when the main shaft of the machine tool rotates, the workpiece and the live center 6 are driven to rotate together;
after the rotating center is used for a period of time, because the sliding block 2 and the sliding rail 3 are continuously rubbed to generate abrasion, the axis of the live center 6 can integrally descend, so that the axis of the live center and the axis of the main shaft are not collinear, an operator can insert the end part of a hexagonal prism wrench into an inner hexagonal hole 11 on the top end face of the eccentric rotating shaft 7 at the moment, the wrench is used for driving the eccentric rotating shaft 7 to rotate, and because the eccentric rotating shaft 7 is eccentric, a pulley 12 which is arranged at the bottom of the eccentric rotating shaft and has the same width as the long groove 13 can circumferentially shift the center sleeve 5 when the eccentric rotating shaft 7 rotates, and the center sleeve 5 is driven to rotate for a certain angle in the tailstock sleeve 4; the inner circle of the pattern formed on the section of the centre sleeve 5 is an eccentric circle, so that when the centre sleeve 5 rotates relatively in the tailstock sleeve 4, the live centre 6 inserted at the front end of the centre sleeve 5 can actually deflect, the deflection can enable the axis of the live centre 6 to move upwards in the vertical direction, but the axis can also generate a certain amount of displacement in the horizontal all-round direction;
through a measuring tool and a corresponding measuring means, the adjusting work is stopped after the axis of the live center 6 is determined to be at the same horizontal height with the axis of the main shaft, the connecting bolt 17 on the adjustable slide block 2 is loosened, the horizontal adjusting gasket 15 with proper thickness is selected and is plugged between the adjustable slide block 2 and the vertical reference surface 16, at the moment, the horizontal adjusting gasket 15 is supported through the supporting plate 14, namely, the coordinate of the axis of the live center 6 in the horizontal direction is adjusted by selecting the horizontal adjusting gaskets 15 with different thicknesses, and after the axis of the live center 6 is collinear with the axis of the main shaft of the machine tool again, the connecting bolt 17 on the adjustable slide block 2 is screwed again;
in the process, the tailstock body 1 is not required to be detached from the sliding block 2, and the live center 6 can be readjusted to be in a state of being coaxial with the main shaft only through simple operation, so that a large amount of labor and operation time are saved.
