Description
Technical field
This utility model is related to a kind of machinery processing apparatus of axle journal class part grinding, is specifically related to a kind of high efficient grinding
The specific purpose tool of axle journal, belongs to machining class field.
Background technology
Mining machinery field, the journal surface roughness requirements Ra0.8 of some parts, and traditional large-scale vertical lathe turning
Surface roughness can only achieve Ra3.2 it is clear that requirement cannot be met, and the method for grinding can only be taken to improve the rough surface of axle journal
Degree.
Common grinding tool has two kinds：One kind is cotton piece buff, and cotton piece buff grinding bistrique matrix is that cotton dolly elasticity is big, therefore grinding
Measure less, generally 0.03mm-0.08mm, when allowance is more than 0.08mm, grinding is more difficult, so to the part chi before grinding
Very little requirement is more strict, and the long-time stress of cotton piece buff can lead to electric machine main shaft modification, and cotton piece buff axial runout is big, and working (machining) efficiency is low.Two
It is emery wheel, although wheel grinding stock removal is big, efficiency high, and bistrique durability is good, requires main shaft circular runout to be less than
0.05mm, actual domestic motor circular runout 0.1mm-0.2mm is unable to reach requirement, relatively costly using high-precision motor.Make
Cutting fluid must be used with wheel grinding, there is environmental pollution.There is severe compromise during emery wheel high-speed rotation, typically do not push away
Recommend and use in open area.
For this reason, how to provide a kind of specific purpose tool of efficient axle journal class part grinding, it is the purpose of this utility model research.
Utility model content
For overcoming prior art not enough, this utility model provides a kind of specific purpose tool of high efficient grinding axle journal, using this reality
With new abrasive belt grinding head, its surface roughness reaches Ra6.3, workpiece linear velocity 120m/min, grinding wheel feed 35mm/min, greatly
Improve greatly grinding efficiency.
For solving prior art problem, this utility model be employed technical scheme comprise that：
A kind of specific purpose tool of high efficient grinding axle journal, including clamping plate, motor, driving wheel, guard shield, abrasive band, tensioning cylinder
And contact wheel；Described clamping plate is connected with lathe cutter saddle, is fixed using lathe jackscrew；Described motor and driving wheel match
Close；Described driving wheel periphery is provided with guard shield；Described driving wheel passes through abrasive band and forms rotation loop with tensioning cylinder；Described
Tensioning cylinder one end be fixedly installed contact wheel.
Further, described motor is arranged on clamping plate, and described tensioning cylinder is arranged on clamping plate.
Further, described motor passes through power drives, and adopts 2.2KV voltage.
Further, described abrasive band surface roughness reaches Ra6.3, workpiece linear velocity 120m/min during grinding, contact
Wheel feeding 35mm/min.
The beneficial effects of the utility model are：Structure is simple, easy to use；Improve work efficiency；Do not need cutting fluid,
Energy-conservation and environmental protection.
Brief description
Fig. 1 is this utility model structural representation.
Wherein：Clamping plate, motor 2, driving wheel 3, guard shield 4, abrasive band 5, tensioning cylinder 6, contact wheel 7.
Specific embodiment
In order that those skilled in the art can more understand technical solutions of the utility model, 1 to this below in conjunction with the accompanying drawings
Utility model is further analyzed.
As shown in figure 1, a kind of specific purpose tool of high efficient grinding axle journal, including clamping plate 1, motor 2, driving wheel 3, guard shield 4,
Abrasive band 5, tensioning cylinder 6 and contact wheel 7；Described clamping plate 1 is connected with lathe cutter saddle, is fixed using lathe jackscrew；Described
Motor 2 is matched with driving wheel 3, and motor is connected with power supply, using 2.2KV voltage；Described driving wheel 3 periphery is provided with guard shield
4；Described driving wheel 3 passes through abrasive band 5 and forms rotation loop with tensioning cylinder 6；Described tensioning cylinder 6 one end is fixedly installed
Contact wheel 7；Abrasive band surface roughness reaches Ra6.3, workpiece linear velocity 120m/min during grinding, and contact wheel feeds 35mm/min.
After power supply is energized, motor rotates and drives driving wheel 3 to rotate, and adjusts tensioning cylinder 6, drives abrasive band 5 to rotate, simultaneously
Start lathe, the rotational speed making workpiece to set, knife rest sets feeding, has certain relative motion with described contact wheel 7,
Thus producing friction to reach ground effect.
The transmission direction in abrasive band 5 should be made during grinding contrary with the rotation direction of workpiece, reach certain relative motion, and produce
The obvious spark of life produces.
Specific purpose tool described in the utility model, according to given grinding method, can be rapidly achieved expected surface thick
Rugosity；Compare traditional method for grinding and instrument, efficiency improves more than 6 times.
Above this utility model specific purpose tool is described in detail, specific case used herein is new to this practicality
The principle of type and embodiment are set forth, and the explanation of above example is only intended to help understand method of the present utility model
And its core concept；Simultaneously for one of ordinary skill in the art, according to thought of the present utility model, in specific embodiment party
All will change in formula and range of application, in sum, this specification content should not be construed as to limit of the present utility model
System.
