Contacted with oilstone cushion block, be provided with connecting key between the corresponding ejector pin guide bracket up and down, the upper and lower corresponding sliding support
Between be provided with support fixed block, be provided with support bar, the oilstone cushion block upper and lower ends between the adjacent sliding support with arranging
It is respectively equipped with extension spring.
Preferably, shown support bar is fixed in the sliding support by hexagon-headed bolt.Stability Analysis of Structures, just
In repair and replacement, and honing effect is good.
Preferably, the connecting key is fixed on the master with the support fixed block by the first soket head cap screw
On mandrel frame.Stability Analysis of Structures, maintenance is conveniently replaceable, and honing effect is good.
Preferably, the sliding support is fixed on the support fixed block by the second soket head cap screw.Knot
Structure is stable, is conveniently replaceable maintenance, and honing effect is good.
Preferably, described sliding support one end is trapezium structure that can be in the nested ejector pin guide bracket, the cunning
The dynamic support other end is plane shuttering panels, and the square groove for being used for installing the oilstone cushion block is provided among the baffle plate.Oilstone cushion block is pacified
In square groove, stability, oilstone contacts well with workpiece during honing, can protect oilstone, improves service life.
Preferably, cone core (7) upper end is provided with packing ring (11).When one side cone core moves up and down with push rod
Cone core is protected, it is another conveniently to make cone core be connected with push rod more to fasten.
Preferably, the main core pedestal top axial is provided with hanging pin.
The beneficial effects of the utility model are：
First, oilstone cushion block of the present utility model is simple in construction in the square groove of sliding support, is conveniently replaceable oilstone
Cushion block and oilstone, and stability is good；
Second, the utility model is simple in construction, easily manufactured, and production efficiency is high, and cost is low, installation, convenient disassembly；
3rd, the level that the utility model is used as promoting oilstone cushion block and its oilstone by the relative slip of ejector pin and cone core
Mobile, so as to adjust the size of honing, harmomegathus size is easily controlled, and can ensure the precision of Honing process.
