A kind of abrasive band polishing double compensation device
Technical field
The present invention relates to a kind of abrasive band polishing double compensation device.
Background technology
Belt sander is the desirable tool of production being applied to the operations such as five metals processing, machine-building, punching press casting, mould, plastic cement, precision component, handicraft industry product surface finish chamfering, deflashing burr, also can carry out the various operation such as plane lapping and radian, angle lap, edging, rounding, polishing to product simultaneously.Traditional belt sander is generally drive whole polishing support movable by cylinder or motor and compensate in polishing operation, because polishing support weight is comparatively large, causes compensating movement delay of response and inertia comparatively large, serious quality of finish.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of abrasive band polishing double compensation device, light structure, compensating movement reaction fast.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of abrasive band polishing double compensation device, include frame, described frame is provided with abrasive band driving mechanism and polishing head mechanism, described frame front end is provided with can the slide of slide anteroposterior, described slide is connected with the first actuating unit for pressing before keeping it, described slide upper surface is provided with turning cylinder, described turning cylinder is hinged with adjustment rack, described adjustment rack is provided with the first end of front end and the second end of rear end, described first end is connected with polishing head mechanism, and described the second end is connected with the second actuating unit rotated for promoting adjustment rack.
As the improvement of technique scheme, described first actuating unit and the second actuating unit are cylinder or servomotor.
As the further improvement of technique scheme, described frame is provided with linear slide rail, described slide is provided with the slide block mated with described linear slide rail.
Further, bearing is provided with between described turning cylinder and adjustment rack.
Further, described polishing head mechanism is provided with clamping plate, and described clamping plate is L-type, and its long limit extends to the end near polishing head mechanism, and its corner is hinged with first end, and its minor face is connected with the 3rd actuating unit to promote clamping plate rotation.
Further, described 3rd actuating unit is cylinder.
Further, described adjustment rack is also provided with the 3rd end, and described 3rd actuating unit is articulated with described 3rd end.
The invention has the beneficial effects as follows: in polishing process, promote adjustment rack reach by the first actuating unit thus carry out the compensation of fore-and-aft direction, rotate by the second actuating unit promotion adjustment rack and polishing head mechanism thus carry out side direction compensation, possesses double compensation function, using the front of polishing head mechanism or side to carry out polishing all can real-Time Compensation, guarantee polishing force is stablized, and improves quality of finish; Because the second actuating unit only promotes adjustment rack and polishing head mechanism rotation, this part-structure is light and handy, lightweight, and compensating movement reaction speed is fast, greatly improves quality of finish.

Detailed description of the invention
With reference to Fig. 1 ~ Fig. 7, a kind of abrasive band polishing double compensation device, include frame 1, described frame 1 is provided with abrasive band driving mechanism 2 and polishing head mechanism 3, described frame 1 front end is provided with can the slide 4 of slide anteroposterior, described slide 4 is connected with the first actuating unit 8 for pressing before keeping it, described slide 4 upper surface is provided with turning cylinder 401, described turning cylinder 401 is hinged with adjustment rack 5, described adjustment rack 5 is provided with the first end 501 of front end and the second end 502 of rear end, described first end 501 is connected with polishing head mechanism 3, described the second end 502 is connected with the second actuating unit 6 rotated for promoting adjustment rack 5, wherein preferred, described first actuating unit 8 and the second actuating unit 6 adopt cylinder, servomotor can certainly be adopted to pass through screw mandrel or gear, rack drives slide 4 moves.Adopt said structure, when adopting abrasive band 5 polishing of polishing head mechanism 3 side, second actuating unit 6 rotates by promoting adjustment rack 5 position namely driving polishing head mechanism 3(and abrasive band 5 polishing) rotate to keep polishing head mechanism 3 side to the pressure of workpiece, especially adopt cylinder as the second actuating unit 6, due to the characteristic of air pressure, second actuating unit 6 can force abrasive band 5 to be tightly pressed on workpiece, and automatically keep polishing head mechanism 3 to maintain action under the lateral pressure state of setting, compensate in real time, reaction fast, guarantee polishing force is stablized, improve quality of finish, second actuating unit 6 directly acts on polishing head mechanism 3, its light structure promoted, therefore compensating movement reaction speed is fast, greatly can improve quality of finish, when adopting abrasive band 5 polishing in polishing head mechanism 3 front, first actuating unit 8 pushes slide 4 and keeps abrasive band 5 maintain action under the front pressure condition of setting and compensate in real time, preferably the first actuating unit 8 adopts cylinder, the characteristic of air pressure is utilized to realize instant compensation, double compensation with the use of, the polishing that can meet all directions compensates needs, and polishing effect is reliable and stable.
In the present embodiment, preferably, described frame 1 being provided with linear slide rail 101 also can adopt other slide unit as optical axis, linear bearing etc., and only need reach the object of slide 4 linear slide, described slide 4 is provided with the slide block 402 mated with described linear slide rail 101.Slide 4 is arranged on linear slide rail 101 by slide block 402, and slide 4 can slide along linear slide rail 101, structure simple and durable, and cost is low, easy to maintenance.
In the present embodiment, preferably, bearing is provided with between described turning cylinder 401 and adjustment rack 5.Because adjustment rack 5 needs frequent rotation, use bearing can ensure that adjustment rack 5 rotates smooth and easy, reliability and durability.
In the present embodiment, preferably, described polishing head mechanism 3 is provided with clamping plate 301, described clamping plate 301 is in L-type, and its long limit extends to the end near polishing head mechanism 3, its corner and first end 501 hinged, its minor face is connected with the 3rd actuating unit 7 and rotates to promote clamping plate 301,3rd actuating unit 7 preferably adopts cylinder, and described adjustment rack 5 is also provided with the 3rd end 503, and described 3rd actuating unit 7 is articulated with described 3rd end 503.Abrasive band 5 is pressed on polishing head mechanism 3 by clamping plate 301, with anti-deviation effect, adopts the 3rd actuating unit 7 to promote clamping plate 301 and rotates, conveniently adjust in real time.
The above, just better embodiment of the present invention, but the present invention is not limited to above-described embodiment, as long as it reaches technique effect of the present invention with any same or similar means, all should fall within protection scope of the present invention.
