A kind of multidirectional belt sander
Technical field
The present invention relates to a kind of multidirectional belt sander.
Background technology
Belt sander is to be applied to five metalworkings, machine-building, punching press casting, mould, plastic cement, precision component, technique conduct
The preferable tool of production of the operations such as industry product surface polishing chamfering, deflashing burr, while plane can also be carried out to product grinding
The various operations such as mill and radian, angle lap, edging, rounding, polishing.Existing belt sander generally uses a belt wheel as rubbing head,
Abrasive band bypasses the belt wheel and the abrasive band using laminating belt wheel is polished, for the workpiece with multiple burnishing surfaces, it is necessary to carry out
To carry out the polishing of different faces, inefficiency expends the time, increases production cost multiple Workpiece clamping.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention to provide a kind of multidirectional belt sander, be provided with multiple burnishing surfaces,
Greatly reduce clamping workpiece number of times, improve efficiency.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of multidirectional belt sander, including organic frame and be arranged in frame abrasive band drive mechanism, strainer,
Polishing mechanism and abrasive band, the polishing mechanism include at least two belt wheels stretched out outside the frame, each belt wheel
Both sides are each provided with a directive wheel, and the directive wheel is pressed in abrasive band outside, and the belt wheel is pressed in abrasive band inner side.
As the improvement of above-mentioned technical proposal, the directive wheel be arranged on so that bypass the abrasive band of the belt wheel for level or
Person arranges vertically.
Used as the further improvement of above-mentioned technical proposal, the belt wheel is provided with two, including horizontally disposed
Horizontal belt wheel and vertical belt wheel is vertically set.
Further, the horizontal belt wheel is connected with mounting bracket, and the mounting bracket is arranged in the frame and can be along level
Slide in direction.
Further, the mounting bracket is connected with for keeping horizontal belt wheel to the compensation device of abrasive band pressure.
Further, the compensation device is cylinder.
Further, the compensation device includes servomotor, the gear installed in servomotor rotating shaft and is installed on institute
State the tooth bar of mounting bracket.
Further, in the frame level linear guides, the mounting bracket is provided with what is matched with the linear guides
Sliding block.
Further, it is relatively-movable tensioning frame, the tensioning that the strainer is included installed in the frame
Tensioning wheel is provided with frame, the tensioning frame is also associated with pusher cylinder.
Further, the frame is additionally provided with abrasive belt deviation rectifying mechanism, and the abrasive belt deviation rectifying mechanism is mutually angle including two
Guide wheel.
The beneficial effects of the invention are as follows:Polishing mechanism is oriented at least provided with two belt wheels stretched out outside the frame
Wheel is pressed in abrasive band outside and belt wheel is pressed in abrasive band inner side, at least forms 4 burnishing surfaces of different directions, and a machine can complete multiaspect
Polishing, multiple faces can be polished for the workpiece clamped one time with multiple burnishing surfaces, reduce clamping workpiece number of times, improve production
Efficiency.Present invention practicality rational in infrastructure, it is easy to use, workpiece polishing can be substantially reduced time-consuming.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the invention;
Fig. 2 is front view of the invention;
Fig. 3 is the structural representation of mounting bracket and horizontal belt wheel in the present invention.
Specific embodiment
1 ~ Fig. 3 of reference picture, a kind of multidirectional belt sander, including organic frame 1 and the abrasive band being arranged in frame 1 drive
Mechanism 2, strainer 3, polishing mechanism 4 and abrasive band 5, the polishing mechanism 4 are stretched out outside the frame 1 including at least two
Belt wheel 401, the both sides of each belt wheel 401 are each provided with a directive wheel 402, and the directive wheel 402 is pressed in outside abrasive band 5
Side, the belt wheel 401 is pressed in the inner side of abrasive band 5.Using said structure, because abrasive band 5 bypasses belt wheel 401 again by two directive wheels
402 push down, at least 2 belt wheels 401 that polishing mechanism 4 stretches out, and will form at least 4 burnishing surfaces, or polishing mechanism 4 stretches out
3 belt wheels 401, will form at least 6 burnishing surfaces, workpiece is changed after a side for belt wheel 401 polishes a face wherein
Can the relative another side of polishing, at least 4 different directions on belt sander of the invention to the another side of the belt wheel 401
Abrasive band polishing face, possess multidirectional polishing function, workpiece clamped one time can be more than 4 faces of polishing, even multiaspect needs to throw
The workpiece of light also just only needs clamping one to secondary, compared to existing belt sander, greatly reduces clamping workpiece number of times,
Improve production efficiency, reduces cost.
In the present embodiment, it is preferred that the directive wheel 402 is arranged on so that the abrasive band 5 for bypassing the belt wheel 401 is water
Flat or vertical arrangement.Burnishing surface for most workpiece is all than more conventional horizontally or vertically plane, sand of the invention
The abrasive band polishing face that band polishing machine is directed to take turns 402 both sides is arranged to horizontally or vertically, be more suitable for common situation, using more
It is convenient.
In the present embodiment, it is preferred that the belt wheel 401 is provided with two, including horizontally disposed horizontal stripes
Take turns 4011 and vertical belt wheel 4012 is vertically set.Using said structure, 2 horizontal burnishing surfaces and 2 are formed with
Vertical burnishing surface, meets the polishing requirement of most workpiece, the optimal using effect gone.
In the present embodiment, it is preferred that the horizontal belt wheel 4011 is connected with mounting bracket 6, the mounting bracket 6 is arranged on institute
State in frame 1 and can slide in the horizontal direction.Preferably, the mounting bracket 6 is connected with for keeping horizontal belt wheel 4011 to sand
Compensation device 7 with 5 pressure, compensation device 7 is cylinder or the gear using installation in servomotor, servomotor rotating shaft
And the structure of the tooth bar of the mounting bracket 6 is installed on, compensation device 7 uses cylinder, using the characteristic of air pressure, horizontal belt wheel
4011 one side can play a part of tensioning, and compensation abrasive band 5 on the other hand can be made to keep the Forward pressure value of setting, improve polishing
Effect.
In the present embodiment, it is preferred that the linear guides 101 of level in the frame 1, naturally it is also possible to use optical axis,
Linear bearing etc., the mounting bracket 6 is provided with the sliding block 601 matched with the linear guides 101, and mounting bracket 6 passes through sliding block 601
On linear guides 101, smooth can slide, structure is reduced, easy to maintenance, low cost.
In the present embodiment, it is preferred that it is relatively-movable that the strainer 3 is included installed in the frame 1
Tensioning frame 301, is provided with tensioning wheel 302 on the tensioning frame 301, the tensioning frame 301 is also associated with pusher cylinder 303.
In the present embodiment, it is preferred that the frame 1 is additionally provided with abrasive belt deviation rectifying mechanism 8, the abrasive belt deviation rectifying mechanism 8
Including two guide wheels for being mutually angle, abrasive band 5 is passed through from two centers of the guide wheel for being mutually angle, and two guide wheels are to abrasive band 5
Side has certain effect power, prevents the sideslip of abrasive band 5.
The above, simply better embodiment of the invention, but the present invention is not limited to above-described embodiment, as long as
It reaches technique effect of the invention with any same or similar means, should all fall under the scope of the present invention.
