Abstract
The invention discloses a fine boring clamp for a cylinder sleeve. The fine boring clamp comprises an upper lining, a clamp cover, a conical handle, a clamp body and a lower lining. The upper lining is located at an opening in the upper end of the clamp body and is connected with the clamp cover. The upper end of the conical handle is connected with the upper lining, and the lower end of the conical handle is connected with the lower lining. According to the fine boring clamp for the cylinder sleeve, different parts are machined through one machine tool, the clamp does not need to be replaced, the clamp amount is reduced, the workload of installing the clamp on the machine tool is reduced, the machining efficiency is improved, and the economic benefits of an enterprise are improved.
Description
Technical field: the present invention 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.
Summary of the invention: for above-mentioned the deficiencies in the prior art, the invention provides a kind of cylinder sleeve fixture for fine boring.
For achieving the above object, the technical solution used in the present invention 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 clamp body supports the outside that square column is fixed by screws in 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 invention enables and 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.
