Specific embodiment
The utility model is described in more detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figures 1 to 5, a kind of stepped hole honing reamer, is used for the inner surface in ream hole, and honing reamer includes master
Knife bar 2, the connection handle 1 being fixedly connected on operator bar 2 rear end, be connected on operator bar 2 be used for hole to be processed
The ream part of the inner surface in ream hole after contact, ream part include be distributed in along operator pole length extending direction on operator bar two
Group honing knife cover 4, what the radial direction of honing knife cover along operator bar 2 can float is arranged on operator bar 2, and honing reamer further includes solid
Surely two guide sleeves 6 being set between operator 2 forepart of bar and two groups of honing knife covers and the installation positioned at 2 front end of operator bar
Nut 7；During honing reamer ream, honing knife cover 4 is formed with the ream face with the contact of the inner surface of stepped hole, and honing reamer is also
The regulating mechanism of radiai adjustment ream face height including being used to making honing knife cover 4 to float and then along the operator bar 2.
Specifically, which includes the push rod 3 for being set in operator bar and connection handle inner circumferential slided, set on two groups of top gems of a girdle-pendant
Three voussoirs 5 whetted a knife between set 4 and push rod 3, when push rod 3 is in operator 1 inner circumferential forward slip of bar 2 and connection handle, three wedges
Block 5 is located remotely from each other along the radially outward side of operator bar 2.Each voussoir 5 has been respectively formed on inclined-plane, is formed on push rod 3 and inclined-plane
The surface groove 30 of cooperation（There are three surface grooves 30, corresponds to the inclined-plane on three voussoirs 5 respectively）, when push rod 3 in operator bar 2 and connects
When connecing 1 inner circumferential forward slip of handle, inclined-plane on voussoir 5 is opposite with the inclined-plane of surface groove 30 to be slided, and three voussoirs 5 are along operator bar 2
Radially outward side float（I.e. three voussoirs 5 are located remotely from each other）, and then honing knife cover 4 is driven to expand outwardly simultaneously feed, i.e., it is above-mentioned
Ream face radially float, the height in ream face increases, by hole ream to the size of needs.
Further, honing knife cover 4 is removably connect with voussoir 5, operator bar 2.Honing knife cover 4 is included with opening
Circular arc set 41 and the multiple tool sections 42 being fixedly connected on 41 peripheries of circular arc set（Tool section is equipped with 6 in this example）, voussoir 5, which is set on, to be justified
The inner surface of the inner circumferential of arc set 41, tool section contact with the inner surface of stepped hole and ream stepped hole, when honing reamer rotates,
The lateral surface of tool section 42 forms the ream face with the contact of the inner surface of stepped hole.
In this example, honing reamer is additionally provided with the oil supply structure to provide cutting oil during 4 ream of honing knife cover.The oil supply structure
Including be opened on connection handle 1 the oil inlet passage 10 connected with connection handle 1 and operator bar 2 inside, be opened on honing knife cover
And with multiple nozzle openings for connecting inside connection handle and operator bar（It is not shown in figure）；Cutting oil enters from oil inlet passage 10
In the internal cavities of connection handle and operator bar, eject injected directly in the stepped hole for treating ream from nozzle opening later
Side, it can quickly take away chip and grinding heat, reduce workpiece deformation, improve surface smoothness.Also it avoids cutting oily splashing
Happen.
In addition, honing reamer is additionally provided with the position limiting structure for limiting pushrod movement distance, which includes opening up
Stroke groove 31 on push rod 3 and outside the radially extending and wearing to the limiting spiral shell in stroke groove 31 along connection handle by connection handle
Nail 32.
During the stepped hole honing reamer ream stepped hole of the utility model, first honing reamer is packed into machine tool chief axis hole,
By the motor-driven mandril of servo feed in spindle hole（It is not shown in figure）The push rod of the utility model is pushed to travel forward.Push rod
Move downward when, the inclined-plane on inclined-plane and voussoir on push rod generates opposite slip, and push rod is axial in operator bar
Thrust be converted to voussoir along the power that floats outward of operator bar diameter so that the tool section of that honing knife cover of honing reamer forepart
Lateral surface expand outwardly, i.e., honing reamer rotate ream when, the height in ream face constantly expands outwardly, and hole ream is arrived
Need size, bottom outlet（Stepped hole is the different two holes composition of radius, and first machined bottom reprocesses the radius above bottom outlet
More than the upper hole of bottom outlet）After ream finishes, lathe drives honing reamer to move down, that honing knife of honing reamer forepart
Set is passed down through bottom outlet, that honing knife cover at honing reamer rear portion moves down supreme hole position, and after honing reamer
Medial surface of the ream face of that honing knife cover in portion in upper hole corresponds to, and and then, push rod pushes down on, after driving honing reamer
The ream of that honing knife cover in portion faces out expansion, until upper hole ream is passed through the top gem of a girdle-pendant of the utility model to size is needed
After mill reamer finishes bottom outlet and upper hole machined, the concentricity in bottom outlet and upper hole reaches 0.003mm and is set hereinafter, meeting drawing
Meter requirement.
In conclusion the stepped hole honing reamer of the utility model sets two groups of honing knife covers onto an operator bar,
Two groups of honing knife covers can be floated, concertedness is good, and the stepped hole concentricity of ream is high outward by the adjusting of regulating mechanism.And
Honing knife cover can float in radial direction, and the regulating mechanism for adjusting its floating is set using the cooperation of the inclined-plane of push rod and voussoir
Meter, i.e., when push rod moves downward, the inclined-plane on the inclined-plane and voussoir on push rod generates opposite slip, and push rod is existed
The thrust of operator bar axial direction is converted to the power that voussoir floats outward along operator bar diameter, ensure that multiple tool sections on honing knife cover
Cylindricity error smaller when expanding outwardly, so as to the precision higher in top gem of a girdle-pendant hole.During honing knife cover expands, axial displacement is
Zero, therefore, in honing process, lathe, fixture are without adjustment.Moreover, honing knife cover is removably attachable on operator bar,
With changing conveniently, the inner circumferential of honing knife cover is that cylinder is sized manufacture, so, it is versatile, it can replace at any time as needed
Abrasion or varigrained or various sizes of honing knife cover.The stepped hole honing reamer structure novel of the utility model,
Compact, guide part bit length, using effect is good.Easily detachable structure designs, and manufacture cost, period, raising is greatly saved
Production efficiency.
The utility model is described in detail above, its object is to allow the personage for being familiar with this field technology can be much of that
It solves the content of the utility model and is implemented, the scope of protection of the utility model can not be limited with this, it is all according to this practicality
The equivalent change or modification that novel Spirit Essence is made should all cover within the protection scope of the present utility model.
