Abstract

The invention discloses a semi-fine boring clamp for a cylinder sleeve. The semi-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 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 semi-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

Cylinder sleeve half fixture for fine boring
Technical field: the present invention is a kind of fixture, especially a kind of cylinder sleeve half 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 half fixture for fine boring.
For achieving the above object, the technical solution used in the present invention is: cylinder sleeve half fixture for fine boring, comprises lining, clamp cover, tapered handle, clamp body and lower lining.Upper lining is in the opening part of clamp body upper end, and is connected with clamp cover.The upper end of tapered handle connects upper lining, and lower end connects lower lining.
Preferably, described clamp body lower end is provided with base.
Preferably, described upper lining and clamp cover are connected by screw.
Preferably, described tapered handle is connected with upper lining and lower lining by connecting axle.
Preferably, described lower lining is fixed by clamp nut and connecting axle.
Preferably, described clamp nut is fixed on clamp body by pin handle.
Preferably, described clamp nut is fixed by packing ring and connecting axle.
Preferably, described clamp nut is connected with connecting axle by slip-knot bolt.
Preferably, described clamp body is put together on together by bolt.
The present invention realize a machine tool process different parts do not need change fixture, decrease fixture amount and saved the workload wanting clamps on lathe, raising working (machining) efficiency, for enterprise increases economic efficiency.

Detailed description of the invention:
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical scheme in the embodiment of the present invention carry out clear, intactly describe, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1
As shown in Figure 1-Figure 3: cylinder sleeve half fixture for fine boring, comprises lining 1, clamp cover 4, tapered handle 6, clamp body 15 and lower lining 13.Upper lining 1 is in the opening part of clamp body 15 upper end, and is connected with clamp cover 4.The upper end of tapered handle 6 connects upper lining 1, and lower end connects lower lining 13.Described clamp body 15 lower end is provided with base 9.Described upper lining 1 is connected by screw 3 with clamp cover 4.Described tapered handle 6 is connected with upper lining 1 and lower lining 13 by connecting axle 5.Described lower lining 13 is fixed by clamp nut 12 and connecting axle 5.Described clamp nut 12 is fixed on clamp body 15 by pin handle 11.Described clamp nut 12 is fixed by packing ring 10 and connecting axle 5.Described clamp nut 12 is connected with connecting axle 5 by slip-knot bolt 7.Described clamp body 15 is put together on together by bolt 16.
Embodiment 2
Cylinder sleeve half fixture for fine boring, comprises lining, clamp cover, tapered handle, clamp body and lower lining.Upper lining is in the opening part of clamp body upper end, and is connected with clamp cover.On upper lining, the external diameter on edge is greater than the external diameter on lower edge.The upper end of tapered handle connects upper lining, and lower end connects lower lining.Described upper lining and clamp cover 4 are connected by screw.Described tapered handle is connected with upper lining and lower lining by connecting axle.Described lower lining is fixed by clamp nut and connecting axle.Described clamp nut is fixed on clamp body by pin handle.Described clamp nut is connected with connecting axle by slip-knot bolt.
During work, control upper lining and the clamping of lower lining realization to cylinder sleeve by tapered handle, 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.
