Abstract

Cylinder liner finish boring anchor clamps, including last bush, anchor clamps lid, toper handle, the anchor clamps body and lower liner cover. Go up the opening part that the bush is in anchor clamps body upper end to be connected with the anchor clamps lid. Upward bush is connected to the upper end of toper handle, and the lower liner cover is connected to the lower extreme. The utility model discloses realize the part that a machine tool machining is different and need not change anchor clamps, reduced the anchor clamps volume and practiced thrift the work load of wanting lathe facial make -up anchor clamps, improve machining efficiency, for the improvement economic benefits of enterprise.

Description

Cylinder sleeve fixture for fine boring
Technical field: the utility model is a kind of fixture, especially a kind of cylinder sleeve fixture for fine boring.
Background technology: during internal combustion engine, under high explosion pressure and combustion temperatures effect, cylinder internal gas pressure is high, and cylinder sleeve internal-external temperature difference is large, and therefore, cylinder jacket is subject to sizable mechanical stress and thermal stress.In addition, piston, in cylinder-barrel surface high-speed slide, makes cylinder liner internal wall be subject to strong friction.Cylinder inner wall is one of surface the most serious of wearing and tearing in internal combustion engine, is also one of most important surface determining internal combustion engine overhaul time, and when inner surface of cylinder liner wearing and tearing exceed certain limit, cylinder sleeve lowers the guide effect of piston, and internal combustion engine becomes rough; The sealing of piston ring declines, and working efficiency of internal combustion engine declines, so cylinder sleeve will be changed in use for some time.
Cylinder sleeve belongs to thin-walled parts, due to the poor rigidity of thin-wall workpiece, very easily produces distortion, affect workpiece size precision and form accuracy in Boring Process by the effect of cutting force and clamping force.Therefore, reasonably selecting clamping method, tool geometry angle, cutting data and carry out cooling and lubricating fully, is all the relation ensureing processing thin-walled workpiece accuracy.
Utility model content: for above-mentioned the deficiencies in the prior art, the utility model provides a kind of cylinder sleeve fixture for fine boring.
For achieving the above object, the technical solution adopted in the utility model is: cylinder sleeve fixture for fine boring, comprises pressing plate, adjustment screw, lining, and carrying bolt, supports square column and base.Pressing plate is fixed on by adjustment screw the upper end supporting square column.Support the outside that square column is fixed on base.Lining is fixed in the groove of base upper end.Carrying bolt is through pressing plate, and lower end is fixed on base.
Preferably, described support square column is fixed by screws in the outside of base.
Preferably, adjusting nut is provided with between described adjustment screw and support square column.
Preferably, the upper end of described carrying bolt is provided with nut.
Preferably, on described carrying bolt, cover has spring, and spring compression is below pressing plate.
Preferably, fastening nut is provided with between described carrying bolt lower end and base.
Preferably, described lining is fixed in the groove of base upper end by Screw.
Preferably, the cross section of described bush inside is stairstepping.
The utility model makes to become along cylinder sleeve axis direction to the clamping force of cylinder sleeve, effectively can eliminate the generation of the part deformation situation that clamping force causes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A direction view of Fig. 1.
Fig. 3 is the structural representation of lining.
Detailed description of the invention:
Below in conjunction with the accompanying drawing in the utility model embodiment, to the technical scheme in the utility model embodiment carry out clear, intactly describe, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment 1
As shown in Figure 1-Figure 3: cylinder sleeve fixture for fine boring, comprise pressing plate 11, adjustment screw 8, lining 7, carrying bolt 4, supports square column 2 and base 3.Pressing plate 11 is fixed on by adjustment screw 8 upper end supporting square column 2.Support the outside that square column 2 is fixed on base 3.Lining 7 is fixed in the groove of base 3 upper end.Carrying bolt 4 is through pressing plate 11, and lower end is fixing on the base 3.Described clamp body supports the outside that square column is fixed by screws in base.Adjusting nut 9 is provided with between described adjustment screw 8 and support square column 2.The upper end of described carrying bolt 4 is provided with nut 12.On described carrying bolt 4, cover has spring 10, and spring 10 is pressed on below pressing plate 11.Fastening nut 6 is provided with between described carrying bolt 4 lower end and base 3.Described lining 7 is fixed in the groove of base 3 upper end by Screw 5.The cross section of described lining 7 inside is stairstepping.
Embodiment 2
Cylinder sleeve fixture for fine boring, comprises pressing plate, adjustment screw, lining, and carrying bolt, supports square column and base.Pressing plate is fixed on by adjustment screw the upper end supporting square column.Support square column is fixed on base outside by multiple screw.Lining is fixed in the groove of base upper end by rivet.Carrying bolt is through pressing plate, and lower end is fixed on base.。Be provided with adjusting nut between described adjustment screw and support square column, be used for regulating the height adjusting screw.The upper end of described carrying bolt is provided with nut, is used for tightening pressing plate.On described carrying bolt, cover has spring, and spring compression is below pressing plate.Fastening nut is provided with between described carrying bolt lower end and base.The cross section of described bush inside is stairstepping.
During work, by the effect of pressing plate, carrying bolt and spring, make to become along cylinder sleeve axis direction to the clamping force of cylinder sleeve, effectively can eliminate the generation of the part deformation situation that clamping force causes.
