Abstract
The utility model relates to a special borer for machining thin-wall sleeves. The special borer for the thin-wall sleeves has simple structure and can ensure the machining precision and the machining roughness of the thin-wall sleeves. The special borer comprises a body, and a left support and a right support are respectively arranged at two sides of the body. The special borer is structurally characterized in that: a bearing seat is arranged between the left support and the right support of the body, a boring rod with a boring cutter in the bearing seat is arranged in spherical static pressure bearings in the left support and the right support, and one end of the boring rod is connected with an output shaft of a lathe.
Description
Technical field
The utility model is to belong to field of machining, relates to a kind of special-purpose boring of processing thin-walled cover in particular.
Background technology
Thin-walled is enclosed within the mechanical field and is widely used, and wherein the filmatic bearing lining is the key core part of import mill parts production domesticization, is to be formed by cylinder sleeve and kamash alloy cast.Axiality requires high, and internal diameter kamash alloy roughness requires to be Ra0.4 μ m, and is thin-walled.Common boring machine difficulty of processing is big, and percent defective is high.
Summary of the invention
The utility model is exactly to the problems referred to above, provides a kind of simple in structure, can guarantee that the machining accuracy of thin-walled cover and the thin-walled of roughness overlap special-purpose boring.
For reaching the above-mentioned purpose of the utility model; The utility model adopts following technical scheme; The utility model comprises lathe bed, and the both sides of lathe bed are respectively arranged with left side support and support with right, is provided with bearing block between left side support and right the support on its structural feature lathe bed; The boring bar that has boring cutter in the bearing block is arranged in the spherical hydrostatic bearing in left side support and right the support, and an end of boring bar is continuous with the output shaft of lathe.
The beneficial effect of the utility model: 1, simple in structure: the left side of the utility model lathe bed is supported and the interior boring bar with boring cutter that is provided with of the right spherical hydrostatic bearing that supports, and an end of boring bar links to each other with the output shaft of lathe, and its member is few, and is simple in structure; Be easy to make and processing.
2, can guarantee machining accuracy and the roughness that thin-walled overlaps: the boring bar of the utility model is arranged in the spherical hydrostatic bearing, and the output shaft of lathe drives the boring bar rotation, because the characteristic of spherical hydrostatic bearing, during the boring bar rotation, the meeting automatic aligning, and operate steadily; The thin-walled cover that external diameter processes is put into and the corresponding bearing block of thin-walled cover external diameter shape, made the thin-walled cover not receive chucking power fully, guaranteed the precision of thin-walled cover and the requirement of roughness.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1 is that left support, 2 is that bearing block, 3 is that boring cutter, 4 is that boring bar, 5 is that right boring bar, 6 is that counterweight, 7 is that right side support, 8 is that spherical hydrostatic bearing, 9 is that universal-joint spindle, 10 is that lathe, 11 is that thin-walled cover, 13 is left boring bar for guiding valve feeds back flow controller, 12 in the accompanying drawing.
The specific embodiment
The utility model comprises lathe bed; The both sides of lathe bed are respectively arranged with left side support 1 and support 7 with right; Be provided with bearing block 2 between left side support 1 and the right support 7 on the lathe bed; The boring bar 4 that has boring cutter 3 in the bearing block 2 is arranged at left side support 1 and supports in the spherical hydrostatic bearing 8 in 7 with the right side, and an end of boring bar 4 is continuous with the output shaft of lathe 10.
Described left side support 1 and the right guiding valve feedback flow controller 11 that is provided with spherical hydrostatic bearing 8 on 7 that supports; The static balance that keeps spherical hydrostatic bearing 8 through guiding valve feedback flow controller 11.
One end of described boring bar 4 links to each other through the output shaft of universal-joint spindle 9 with lathe 10.
Be provided with counterweight 6 corresponding to boring cutter 3 on the described boring bar 4, the stability when guaranteeing boring bar 4 rotations.
Described boring bar 4 is combined with right boring bar 5 by left boring bar 13; Be convenient to thin-walled cover 12 is loaded on the bearing block 2.
During processing thin-walled cover 12, the external diameter with thin-walled cover 12 processes earlier; External diameter according to thin-walled cover 12 is provided with bearing block 2 then, and is not enough like bearing block 2 precision, can carry out time processing with 3 pairs of bearing blocks of boring cutter 2 earlier; Again thin-walled cover 12 is placed on the boring bar 4, and is positioned on the bearing block 2; Start lathe 10, the output shaft of lathe 10 drives boring bar 4 through universal-joint spindle 9 and rotates, and 3 pairs of thin-walled covers 12 of the boring cutter of boring bar 4 are processed; Because the shape of bearing block 2 is consistent with the shape of thin-walled cover 12, so bearing block 2 do not receive chucking power, can not produce distortion; Guarantee the axiality and the roughness of bearing block 2, reached designing requirement.
