Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Such as Fig. 1, shown in 2, a kind of abrasive band mill apparatus, including tension mechanism 1, expansion tightening wheel 2, abrasive band 3, offside door 4, offside door
5th, it is small cover 6, contact wheel 7, wheel guard 8, grinding carriage 9, tension mechanism support 10, motor 11, grinding wheel spindle 12, belt pulley A13,
Belt pulley B14.
Wheel guard 8 is fixed on grinding carriage 9, and the rear side of grinding carriage 9 installs tension mechanism 1 by tension mechanism support 10, rises
The tight connection of mechanism 1 expansion tightening wheel 2, the contact wheel 7 is on grinding wheel spindle 12, and the abrasive band 3 is mounted in contact wheel 7 and expansion tightening wheel 2
On, and around contact wheel 7 and expansion tightening wheel 2.Cylinder in the connection tension mechanism 1 of expansion tightening wheel 2.The grinding wheel spindle 12 passes through belt
Wheel and belt connection motor 11.Opening the gas source switch in tension mechanism 1, then cylinder drives the tensioner abrasive band of expansion tightening wheel 2, by electricity
Motivation 11 drives grinding wheel spindle 12 to rotate by a pair of belt pulley A13, belt pulley B14, and drives the contact wheel on main shaft
Rotate.The front and back position of adjustment grinding carriage 9 makes abrasive band with workpiece Elastic Contact to reach ground effect.Open offside door 4 and the right side
The then replaceable sand band of side door 5, changes abrasive band fast and easy.
As shown in Figures 3 to 5, the structure design of contact wheel 7 is similar with flat belt design, and the inner core of contact wheel 7 uses aluminium alloy
Material, in the surface bag last layer rubber elastic material of contact wheel 7, the performance and shape of outermost material are right in grinding
The resection rate and crudy of institute's rapidoprint have direct relation.Soft material is used for polishing, and medium hardness material is used for
General grinding, hard material is processed for accurate grinding.Contact wheel surface configuration is made such as the oblique tooth-shaped of figure three to increase
Cutting power.The emery wheel size of the size of contact wheel 7 and this lathe standard configuration is approached.
Abrasive band can select the different trades mark, selection requirements according to different workpiece material and processing request：（1）More than work pieces process
Amount is big, it is desirable to grinding efficiency it is high should select coarseness, conversely, fine granularity should be selected.Generally, same kind of parts is processed
When, sbrasive belt grinding efficiency is higher than wheel grinding efficiency, because the abrasive particle almost all of abrasive band top layer proper alignment can be played
Ablation, it is big to add the depth ratio emery wheel that abrasive particle is embedded in workpiece surface, so when workpiece surface roughness requires identical, sand
Band abrasive grain answers thin No. one than emery wheel abrasive grain, and once in the special cylindrical grinder experiment in our factory one, result of the test is also demonstrated that
The abrasive band of identical wear particle size and emery wheel, the workpiece surface quality of sbrasive belt grinding is better than the surface quality of wheel grinding and efficiency
Also improve nearly 30%.（2）In the case of workpiece roughness requirements identical, abrasive band linear velocity it is high preferably use fine granularity, linear velocity
Low preferably uses coarseness.（3）If processing, metal material is identical with nonmetallic materials surface quality requirements, and metal uses fine granularity face
It is nonmetallic to select inclined coarseness.（4）Dry waste selects granularity partially thick than wet-milling when processing workpiece of the same race.（5）Process the choosing of toughness greatly inclined
Coarseness；The big steel of workhardness select partially thin granularity.
The corresponding sbrasive belt grinding speed of different rapidoprints is also different.General carbon steel abrasive band linear velocity is 25~38m/s,
Steel alloy, stainless steel are 20~30m/s, nonmetallic then abrasive band linear velocity more low spot relatively.A steel alloy is ground in this experiment pilot scale
The straight roller of material, when abrasive band linear velocity is higher than 30m/s, roll surface occurs as soon as chatter mark, and after speed lowers, chatter mark also with
Disappear.
Expansion tightening wheel during sbrasive belt grinding as the term suggests mainly play a part of to be tensioned abrasive band, and abrasive band is elastomer, is not had
There is certain tensile force, do not have the effect of grinding.In grinding process, the size of tensile force directly affects processing efficiency and added
Working medium amount.Expansion tightening wheel be designed to it is chevron shaped, i.e., in the middle of it is high, two is low, it is therefore an objective to prevent from deviateing during the high-speed grinding of abrasive band rising
Bearing up pulley.On the one hand the diameter of expansion tightening wheel will consider posting ability of the cornerite size to abrasive band in operation process, the opposing party
Bread angle is too small, skidding easily occurs, another aspect contact wheel with expansion tightening wheel external diameter than differing too big, then tensioner wheel speed
It is too fast to directly influence the crudy of workpiece surface, such as there is chatter mark.
User selects different grinding methods as requested：Two kinds of forms of wheel grinding or sbrasive belt grinding are used, and are installed
It is convenient.Also it can be ground according to different grinding workpiece materials and surface requirements from different abrasive bands.The utility model is filled
Category enclosed sbrasive belt grinding form is put, using endless abrasive belt.The utility model device is installed and the same plain external grinding machine of type of drive
Form is identical, i.e., the present apparatus is driven grinding wheel spindle by grinding carriage upper motor loaded on grinding carriage side by a pair of belt pulleys
Rotate, and drive the contact wheel on main shaft to rotate.Expansion tightening wheel then passes through cylinder by the Tensioning structure on rear side of grinding carriage
To adjust the position of expansion tightening wheel to reach the purpose in stretching abrasive band.
In summary, more preferable surface quality and more accurately size can be obtained using the utility model abrasive belt device.Also
Clear superiority with production efficiency height, service life length.And because abrasive band is convenient to mount and dismount, the advantage such as price is easy, with emery wheel
Grinding is higher compared to economic and practical.With the development and breakthrough of Abrasive Belt Technology, abrasive band mill application also will be more and more extensive.Therefore this
Utility model abrasive belt device will be received and be applied by increasing machinery industry.
