Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As Fig. 1, shown in Fig. 2, the utility model relates to a kind of high accuracy long sleeve borer, be provided with boring bar 1, long sleeve 4, back-up block 5, boring table 6, rear support structure 12, it is characterized in that: described long sleeve 4 is in being laterally placed on boring table 6, the back-up block 5 of six sustained heights is provided with in the bottom of long sleeve 4, long sleeve 4 is supported boring table 6 plane by back-up block 5, described boring bar 1 is inner through long sleeve 4, boring bar 1 left end is connected on boring spindle dish, boring bar 1 right-hand member is provided with rear support structure 12, boring bar 1 can horizontally slip in rear support structure 12.
High accuracy long sleeve borer described in the utility model, its boring bar 1 is provided with solid 13, boring cutter hole 2, hollow pipe 3, air vent 7, it is characterized in that: be respectively provided with one solid 13 at the two ends, left and right of boring bar 1, can guarantee that boring bar 1 has good rigidity man-hour adding for solid 13, solid 13 sides are provided with boring cutter hole 2, the floating boring tool of boring long sleeve 4 is arranged in boring cutter hole 2, hollow pipe 3 is provided with the centre of two solid 13, hollow pipe 3 can add at boring bar 1 and plays cushioning effect man-hour, hollow pipe 3 is provided with two air vents 7, air vent 7 can ensure that hollow pipe 3 is inner consistent with external pressure, prevent from being heated during boring bar 1 High Rotation Speed, internal pressure increases makes boring bar 1 produce distortion.
High accuracy long sleeve borer described in the utility model, thereafter supporting construction 12 is provided with copper sheathing 8, large support 10, adjusting pad 11, it is characterized in that: described copper sheathing 8 is arranged on the left end of large support 10, copper sheathing 8 endoporus prepares gap according to boring bar 1 right-hand member solid 13 excircle dimensions, be provided with in the upper end of large support 10 tank filler sleeve 9 that penetrates copper sheathing 8, be provided with the adjusting pad 11 of four same sizes in the bottom of large support 10.
The utility model in use, long sleeve 4 is pressed on boring table 6, first by the overall match grinding of adjusting pad 11 in rear support structure 12, make boring bar 1 center line and copper sheathing 8 center line, long sleeve 4 center line on the same line, and boring bar 1 can according to setting horizontally slipping in copper sheathing 8 of tolerance appropriateness, lubricating oil is added, to reduce the resistance that boring bar 1 operationally moves left and right and the wearing and tearing reducing copper sheathing 8 in large support 10 upper end tank filler sleeve 9.When needs boring long sleeve 4 left-hand axis cushion cap, first boring table 6 is started right-most position, it is inner that long sleeve 4 is left in boring bar 1 upper left side boring cutter hole 2, boring cutter is installed in boring cutter hole, left side 2, open boring switch, along with boring table 6 is slowly to left movement, progressively complete the processing of left-hand axis cushion cap in long sleeve 4; When needs boring long sleeve 4 right-hand axis cushion cap, first boring table 6 is started left-most position, on boring bar 1, long sleeve 4 inside is left in boring cutter hole 2, right side, boring cutter is installed in boring cutter hole, right side 2, open boring switch, along with boring table 6 slowly moves right, progressively complete the processing of right-hand axis cushion cap in long sleeve 4.In whole process, without relative motion between long sleeve 4 and boring table 6, copper sheathing 8 internal slide on the right side of boring bar 1 all the time in rear support structure 12, ensure that boring bar 1 center line all the time with long sleeve 4 center line on the same line, and due to the restriction of copper sheathing 8 in rear support structure 12, boring bar 1 right radial is beated and is remained in very little scope, ensure that the axiality requirement of long sleeve 4 inside left pedestal and right-hand axis cushion cap.
