Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of grinder for polishing dress suitable for handware
It sets, a kind of grinder for polishing being applicable in handware, including sliding mainboard 1, sliding 1 one end of mainboard is fixedly connected by support plate
Grinding wheel 2 and lower grinding wheel 3, upper grinding wheel 2 is bigger than the wheel footpath of lower grinding wheel 3, and two grinding wheels are separately mounted to sliding mainboard 1
The place up and down on right side, and upper grinding wheel 2 and lower grinding wheel 3 are aligned installation in the outer part, the other end for sliding mainboard is equipped with tensioning
Device 4 and driving device 5, tensioning apparatus 4 include tensioning wheel 401 and tensioning cylinder 402, are provided with abrasive band slot on tensioning wheel 401,
Abrasive band 6 is mounted on driving wheel 501 and tensioning wheel 401, upper grinding wheel 2, on lower grinding wheel 3, the tensioning wheel 401 when abrasive band rotates
Can be around System of Rotating about Fixed Axis, this dead axle is connected to the tailpiece of the piston rod of tensioning cylinder 402 by bracket, inputs tensioning cylinder by adjusting
402 air pressure, tailpiece of the piston rod are released, to push the dead axle on bracket, release tensioning wheel 401 outward, reach adjustment sand
Purpose with the frictional force between 6 and upper grinding wheel 2 and lower grinding wheel 3, driving device 5 include driving wheel 501, synchronizing wheel 502,
Synchronizing wheel 502 is connect by shaft coupling with driving wheel 501, and the quantity of synchronizing wheel 502 is two, and two tuningout wheels 503 are set respectively
It sets on the wheel face both sides of two synchronizing wheels 502, by synchronous belt 504 respectively by two tuningout wheels 503 and two 502 phases of synchronizing wheel
Even, when motor is opened, driving wheel is started turning, to drive synchronizing wheel 502 to rotate by shaft coupling, and then synchronous belt 504
Tuningout wheel 503 is driven to rotate, by adjusting the position for fixing two tuningout wheels 503 again, it is possible to reduce sander is in the course of work
In the radial displacement that is generated due to vibration, the friction between abrasive band 6 and grinding wheel can also be adjusted by adjusting 501 position of driving wheel
Power, the middle part of sliding mainboard 1 are provided with dynamic balance mechanism 7, and dynamic balance mechanism 7 includes that power controls cylinder 701, electric Proportion valve
702 are fixedly mounted on support frame 8 with force snesor 703, power control 701 one end of cylinder, and power controls the tailpiece of the piston rod of cylinder 701
It is fixedly connected on sliding mainboard 1, electric Proportion valve 702 that can be automatically controlled can control the air pressure size of dynamic balance cylinder 701, thus
Dynamic balance slide rail 9, dynamic balance slide rail is also mounted in the bottom of 701 power output of control force balance cylinder, sliding mainboard 1
9 include sliding bottom 901, sliding axle 902, and the sliding bottom 901 is fixedly mounted on sliding mainboard 1, and sliding axle 902 is fixed
It is mounted on support frame 8, sliding bottom 901 forms dynamic balance slide rail 9 by sliding bearing 903 and sliding axle 902, and power is flat
Weighing apparatus slide rail 9 effect be, 702 control force balance cylinder 701 of electric Proportion valve air pressure in the feelings for being maintained at setting value
Under condition, when grinding force is greater than cylinder power output, sliding mainboard 1 retreats on dynamic balance guide rail 9, and abrasive band 6 is squeezed with workpiece
The reduction of pressure amount, grinding force reduce, and when grinding force is less than cylinder power output, sliding mainboard 1 advances, abrasive band 6 and workpiece
Amount of compression increases, grinding force increases, and realizes the control of grinding force in principle, it is possible to reduce robot operator
Program teaching burden.
In the utility model, 8 side of support frame is connected with pusher cylinder 10, can entire grinding device be released or be withdrawn,
With adapt to robot process automatically in different technique for grinding.
The utility model is avoided due to the unstable generation of polishing dynamics of Wear Mechanism of Abrasive Belt and the generation of worker's offhand
Quality and problem of appearance, the polishing power for being subject to handware product in polishing are stablized, and good product consistency also reduces enterprise
The requirement of the polishing skill and polishing experience of air exercise grinder people, meanwhile, polishing power is controlled by dynamic balance mechanism, and abrasive band is made to exist
Wear it is relatively high in the case where be still capable of processing out qualified product, increase the utilization rate in abrasive band.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that a variety of to the progress of these embodiments can change without departing from the principles and spirit of the present invention, modify,
Replacement and change modification, the scope of the present invention is defined by the appended.
