It is of the present utility model to reduce the honing head that honing is scratched refering to shown in Fig. 1-2, including body 8, the top seat 6 of honing,
Honing head rises core 7 and hone stone 5；Body 8 includes the body 82 of the first noumenon 81 and second, in the body 82 of the first noumenon 81 and second
Between the top seat 6 of connection honing, the center of the top seat 6 of the first noumenon 81, the second body 82 and honing is designed with through hole, honing
Head rises by core 7 through the first noumenon 81 and the through hole of the top seat 6 of honing, and hone stone 5 is a plurality of, along the outer of the top seat 6 of honing
Surface is uniform, 2 ° of -4 ° of * 15mm chamfering is respectively provided with along the two ends of the length direction of hone stone 5, along the width of hone stone 5
Both sides set 20 ° of -40 ° of * 0.5mm chamfered edge.
The utility model, will be original by being respectively provided with 2 ° of -4 ° of * 15mm chamfering at the two ends of the length direction of hone stone 5
Simple chamfering serves processing guide effect, improves the stability of the locating and machining of hone stone 5, by along the width of hone stone 5
The both sides in direction set 20 ° of -40 ° of * 0.5mm chamfered edge, change original more random manual chamfered edge, improve hone stone 5
Effective rate of utilization, significantly reduces cost.The honing head wear rate drops to 2um/ thousand from former thick top gem of a girdle-pendant 12.29um/ thousand,
Smart top gem of a girdle-pendant 12.17um/ thousand drops to 0.5um/ thousand, when wear rate declines reflection processing honing particle be in progressively abrasion rather than
Broken state.Scuffing rate drops to 0.01% from 0.41%.
Preferably, in order to improve honing head rise core 7 moved in through hole when limiting buffer effect, the second body 82
Push rod 3 and contracting knife spring 4 are additionally provided with through hole, push rod 3 is located at honing head and risen between core 7 and contracting knife spring 4.And in order to top
Bar 3 and contracting knife spring 4 are protected, and honing head also includes a closed end cap 1, and closed end cap 1 is located at one end of the second body 82.
Preferably, honing head also includes rising core spring 2, and honing top news seat 6 is respectively arranged at the two ends with a circular groove, and rise core
Spring 2 is located in the circular groove.The core spring 2 that rises can be resetted after the top seat 6 of honing is moved radially.
Preferably, honing head rises tensioner of the core 7 including cylindrical section 71 and with taper section 72, and tensioner with taper section 72 is located at
In the through hole of honing top news seat 6, it can so facilitate tensioner section 72 and the abutting of push rod 3, it is to avoid with the top inwall of seat 6 of honing
Interference.Wherein, the large end face of the tensioner section 72 with taper is connected with cylindrical section 71.O-ring 9 is located at the appearance of the first noumenon 71
On face.
Preferably, honing head includes a motor 10, and motor 10 is located at the honing head and risen the high order end of core 7, in motor
Under driving, the honing head rises axial movement of the core 7 in the through hole, and hone stone seat 6 drives along radial direction spreading or contraction
Hone stone 5 does corresponding spreading or contraction.The utility model is not limited to drive by motor form, can also be by other
Form drives, including the drive form such as hydraulic pressure, cylinder, as long as can reach that honing head rises axial direction fortune of the core 7 in the through hole

Operation principle of the present utility model is as follows：
During Honing process, by motor 10 the honing head core 7 that rises will be driven to move right, and make the outside spreading of hone stone 5 to adding
Chinese musical scale is very little, and then honing head rotates into connecting rod macropore, and connecting rod positioning starts reciprocal Honing process after clamping.After machining,
Honing head exits connecting rod, and the driving honing head of motor 10 core 7 that rises is retracted to the left, honing head rise core 7 in the presence of contracting knife spring 4 to
Move left, hone stone 5 is retracted to reset condition in the presence of the core spring 2 that rises.
Honing head Central Plains hone stone chamfering is 0 ° 11 ' 28 of size, and " surface has been after * 15mm, hone stone thickness abrasion 0.1mm
There is no chamfering, honing head positioning and guiding impaired performance is deteriorated, and influences post-production stability., can be by honing in utility model
The chamfer design of bar 5 is 3 ° of * 15mm, is effectively utilized 1.5mm honing rule thickness, hone stone is maintained in usage cycles
The guide-localization effect of effect.Again because former hone stone side edge chamfering is uneven relatively arbitrarily, so can also be by chamfered edge standard
Preferable it is established as 30 ° of * 0.5mm.
As one preferably, hone stone could be arranged to 10, and uniform on the outer surface of hone stone seat 6.
Make to keep effective guiding stabilization in hone stone usage cycles.Preferred as one, honing head rises by core 7 can be with 2 °
Taper.
The above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
