Description
Technical field
The invention belongs to honing technique field, and in particular to a kind of honing head.
Background technology
In machine-building, honing is a kind of method of work inner surface microstoning, mainly plays finishing, finishing work
With.Honing head is complicated by being typically made up of multiple parts.And in honing process, change with the specification of workpiece, honing head
Often replacing is needed, further, since honing abrasive belt is easiest to abrasion, or even is damaged, it is also desirable to frequent replacing.The top gem of a girdle-pendant is changed at present
The method of bistrique and emery stick is artificial unloading, and dismounting speed is slow, and workman labor intensity than larger, waste time and energy.Cause
How this, quickly change honing head emery stick, reduces cost of labor, is the key factor that honing efficiency is improved.
Set in the honing head used at this stage, its cone multiple promotion conical surfaces promote oil stone bases and its oilstone harmomegathus with up to
Adapt to machined surface in processing, the distance between multiple conical surfaces and angle agreement it is difficult to ensure that, oil stone base during Honing process
And its oilstone harmomegathus is unstable, the form accuracy of workpiece after honing is caused not reach the requirement of user；And the processing of multiple conical surfaces
Need to expend more times and cost.
In addition, the oilstone and oil stone base of traditional honing head are all integral types, not only cost is high, and after oilstone is deformed
Artificial repair is needed when taper is produced in such as use, it is impossible to carry out oilstone replacing and reach quickly to put into production again, it is time-consuming
Take a lot of work, production efficiency is relatively low；Other oilstone and oil stone base integral type, size are larger, install and use also inconvenient.

Honing head.
The present invention, including main mandrel frame, ejector pin, the cone core for being arranged on the main mandrel frame center, 8 ejector pin guide brackets, oil
Stone, the cone core upper end is connected with push rod, and the push rod upper end is provided with spring；Wherein, two are provided with the outside of the main mandrel frame
The mounting hole of cruciform symmetry is arranged, described ejector pin guide bracket one end is arranged in the mounting hole, the other end peace of the ejector pin guide bracket
Equipped with sliding support, the sliding support end is provided with oilstone cushion block, and the oilstone is arranged on the oilstone cushion block, described
Ejector pin is located in main mandrel frame, sliding support and ejector pin guide bracket hole, described ejector pin one end and cone core taper-face contact, the other end and oil
Stone cushion block is contacted, and is provided with connecting key between the corresponding ejector pin guide bracket up and down, is set up and down between the corresponding sliding support
There is support fixed block, be provided with support bar, the oilstone cushion block upper and lower ends difference between the adjacent sliding support with row
Provided 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, is conveniently replaceable maintenance, 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 to be provided with the square groove for being used for installing the oilstone cushion block in the middle of plane shuttering panels, the baffle plate.Oilstone cushion block is pacified
In square groove, stability, oilstone is contacted 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 mandrel frame top axial is sold provided with extension.
The beneficial effects of the invention are as follows：
First, oilstone cushion block of the invention is arranged on simple in construction in the square groove of sliding support, is conveniently replaceable oilstone cushion block
And oilstone, and stability is good；
Second, the present invention is simple in construction, easily manufactured, and production efficiency is high, and cost is low, installation, convenient disassembly；
3rd, the present invention is used as promoting the level of oilstone cushion block and its oilstone to move by the relative slip of ejector pin and cone core
Dynamic, so as to adjust the size of honing, harmomegathus size is easily controlled, and ensure that the precision of Honing process.
