Description
Technical field
The utility model is related to cylinder jacket machining frock, especially a kind of cylinder jacket heavy boring fixture.
Background technology
In general, it is heavy boring endoporus that cylinder jacket, which machines the first procedure, and its crudy is related to liner blank
Percent defective and the crudy of next procedure.Heavy boring frock in the past has the following disadvantages：1st, heavy boring exhaust hood set endoporus wall thickness
Difference is overproof；2nd, cylinder liner blank external diameter in part is bigger than normal, is not placed into centring ring, or microcephaly is stuck in gland, is not taken not come out；3rd, more
When changing different cylinder sleeve kinds, heavy boring frock is accordingly changed.
The content of the invention
The purpose of this utility model is：A kind of cylinder jacket heavy boring fixture is provided, the fixture positions the cylinder sleeve of arbitrary dimension
It is cylindrical, cylinder sleeve positioning precision is improved, frock is reduced and changes, improve efficiency, reduce cost.
Technical solution of the present utility model is：The cylinder jacket heavy boring fixture includes hydraulic jack, terminal pad, upper positioning
Circle, lower centring ring and base, piston, oil cylinder upper press cover, cylinder body and oil cylinder lower cover composition hydraulic jack, piston, terminal pad,
Upper centring ring, lower centring ring, base are all hollow structure, and cylinder body is arranged on lathe bed, and terminal pad is arranged on piston, upper fixed
Position circle is arranged in terminal pad, and floor installation is on lathe bed, and lower centring ring is arranged on base, in upper centring ring, lower centring ring
Respectively circumferentially decile sets in three positioning post holes, hole and is respectively mounted adjustment screw, spring and locating dowel, and spring is placed in positioning
Between post and adjustment screw.
Wherein, the conical surface is set on base.
When work：By cylinder liner blank three locating dowels of rolled product variety adjustment diameter dimension circumferentially, be allowed to omit
It is cylindrical less than blank；Cylinder liner blank is put into centring ring, lower centring ring by locating dowel automatic capturing, the big end of cylinder liner blank
It is placed on the conical surface of base；Centring ring compresses downwards the boring cutter on cylinder liner blank, main shaft in startup hydraulic jack, drive
Swivel feeding, cuts the inner surface of cylinder liner blank.
The utility model has the advantages that：1st, using adjustable fixed with spring in the upper centring ring of the device, lower centring ring
Position post, the cylinder sleeve for positioning arbitrary dimension is cylindrical, and can realize the automatic capturing to cylinder jacket, and endoporus wall thickness is processed in accurate positioning
Difference is small；2nd, the conical surface is set on base to prevent liner blank radial direction sideslip；3rd, for different cylinder sleeve kinds, adjustment need to only be adjusted
Screw changes circumferential size where locating dowel, saves frock, reduces cost, easy to operate, improves efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is enlarged drawing at A in Fig. 1.
In figure：1 piston, 2 oil cylinder upper press covers, 3 cylinder bodies, 4 oil cylinder lower covers, 5 terminal pads, centring ring on 6,7 cylinder sleeves hair
Base, 8 times centring rings, 9 bases, 10 adjustment screws, 11 springs, 12 locating dowels, 13 conical surfaces.
Embodiment
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the cylinder jacket heavy boring fixture includes hydraulic jack, terminal pad 5, upper centring ring 6, lower centring ring

Centring ring 6, lower centring ring 8, base 9 are all hollow structure, and cylinder body 3 is arranged on lathe bed, and terminal pad 5 is arranged on piston 1,
Upper centring ring 6 is arranged in terminal pad 5, and base 9 is arranged on lathe bed, and lower centring ring 8 is arranged on base 9, upper centring ring 6,
Each circumferentially decile sets in three positioning post holes, hole and is respectively mounted adjustment screw 10, spring 11 and locating dowel in lower centring ring 8
12, spring 11 is placed between locating dowel 12 and adjustment screw 10.
Wherein, the conical surface 13 is set on base 9.
When work：By cylinder liner blank three locating dowels 12 of rolled product variety adjustment diameter dimension circumferentially, be allowed to
It is slightly less than blank cylindrical；Cylinder liner blank 7 is put into centring ring 6, lower centring ring 8 by the automatic capturing of locating dowel 12, cylinder sleeve hair
The big end of base 7 is placed on the conical surface 13 of base 9；Start centring ring 6 in hydraulic jack, drive and compress cylinder liner blank 7 downwards, it is main
Boring cutter on axle can swivel feeding, the inner surface of cylinder liner blank 7 is cut.
