As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, an abrasive belt polishing structure 10 for polishing a workpiece by a multi-axis polishing machine instead of a polishing wheel comprises: abrasive belt 100, polishing body 200, and offset tensioning mechanism 300. The polishing main body 200 is arranged on the multi-axis polishing machine, the abrasive belt 100 is arranged on the polishing main body 200, the abrasive belt 100 is tensioned through the deviation adjusting tensioning mechanism 300, so that the abrasive belt 100 is fixed on the polishing main body 200, when the multi-axis polishing machine is started, an output shaft of the multi-axis polishing machine drives a driving wheel on the polishing main body 200 to rotate, and then the abrasive belt 100 is rotated to polish a workpiece, because the abrasive belt 100 is a flexible grinding tool, the surface of the workpiece can be tightly attached, the polishing operation is completed under the condition that the structure of the workpiece is not influenced, and the polishing effect is better.
Referring to fig. 1 and 2, the polishing main body 200 includes a bearing base 210, a driving wheel 220 and a plurality of driven guide wheels 230, the driving wheel 220 and the plurality of driven guide wheels 230 are disposed on the bearing base at intervals, the abrasive belt 100 sequentially covers the driving wheel 220 and the plurality of driven guide wheels 230, the driving wheel 220 drives the abrasive belt 100 to rotate for polishing a workpiece to be polished, a movable polishing positioning jig 231 is disposed between every two adjacent driven guide wheels 230, the movable polishing positioning jig 231 partially jacks up the abrasive belt 100, and during polishing, a region of the jacked-up abrasive belt 100 is tightly attached to a surface of the workpiece to be polished, which needs to be polished.
When the polishing main body 200 is disposed on a multi-axis polishing machine, the bearing base 210 is fixed on a main shaft of the multi-axis polishing machine, the driving wheel 220 is in butt joint with an output shaft of the multi-axis polishing machine, the output shaft of the multi-axis polishing machine is used for driving the driving wheel 220 to rotate, so as to drive the abrasive belt 100 to rotate, and the movable polishing positioning jig 231 disposed between the two driven wheels 230 drives the abrasive belt 100 to be attached to a surface of a workpiece to be polished, which is to be polished, so as to perform polishing.
During polishing, the workpiece to be polished and the movable polishing positioning jig 231 are respectively located at two sides of the abrasive belt 100, and the movable polishing positioning jig 231 enables the abrasive belt 100 to be attached to the surface of the workpiece to be polished.
Referring to fig. 1 and 2, the offset-adjusting tensioning mechanism 300, the driving wheel 220 and the driven guide wheels 230 are disposed on the carrying base 210 at intervals to form a plurality of supporting points, so as to maintain the tensioning state of the abrasive belt 100. In order to ensure that the abrasive belt 100 can be tightly attached to the surface of a workpiece during polishing, a polishing area of the abrasive belt group polishing structure 10 is arranged between two adjacent driven guide wheels 230, a movable polishing positioning jig 231 is arranged between the two adjacent driven guide wheels 230, the movable polishing positioning jig 231 supports the abrasive belt 100, the attaching force between the abrasive belt 100 and the surface of the workpiece to be polished is increased, and therefore the surface of the workpiece to be polished and the abrasive belt can be tightly attached during polishing, and the polishing quality is ensured.
It should be noted that, in order to deal with different workpieces to be polished, the movable polishing positioning jig 231 can be replaced independently, and only the corresponding movable polishing positioning jig 231 needs to be reassembled onto the carrying base 210, so that the abrasive belt 100 can be tightly matched with the surface of the workpiece to be polished during polishing.
For example, in an embodiment, referring to fig. 3, in order to adapt to a cylindrical workpiece to be processed, the movable polishing positioning fixture 231 includes a backrest adjusting block 231a and two supporting shafts 231b, the backrest adjusting block 231a is installed in the adjusting groove, the two supporting shafts 231b are installed on the backrest adjusting block, the two supporting shafts 231b are both attached to the abrasive belt 100, a gap is left between the two supporting shafts 231b, the cylindrical workpiece to be processed presses and holds the abrasive belt 100 to be embedded into the gap between the two supporting shafts 231b during polishing, at this time, the abrasive belt 100 can cover more area of the cylindrical workpiece to be processed, and the polishing efficiency is higher.
For another example, referring to fig. 4, in order to polish a workpiece to be processed whose surface to be polished is a plane, the movable polishing positioning fixture 231 includes an adjusting slider 231c, a supporting block 231d and a backrest block 231e, the adjusting slider 231c is disposed in the adjusting slot, the supporting block 231d is mounted on the adjusting slider 231c, the backrest block 231e is disposed on a side surface of the supporting block 231d, and the backrest block 231e is attached to the abrasive belt 100. The surface of the backrest block 231e, which is attached to the abrasive belt 100, is a plane, so that the workpiece to be processed is prevented from pressing the abrasive belt 100 to deform during polishing, and the surface of the workpiece to be processed, which does not need to be polished, is ground.
Further, referring to fig. 1 and fig. 2, when workpieces to be polished of the same type and different sizes are handled, since the surfaces to be polished are the same, only the distance from the surface to be polished to the abrasive belt 100 changes, it is not cost-effective to replace the movable polishing positioning jig 231, therefore, in order to improve the adaptability of the abrasive belt group polishing structure 10, an adjusting groove is formed on the bearing base 210, the movable polishing positioning jig 231 is located in the adjusting groove, and according to workpieces to be polished of different sizes, the fixing position of the movable polishing positioning jig 231 in the adjusting groove can be adjusted, so that the same abrasive belt group polishing structure 10 can adapt to the polishing requirements of various workpieces to be polished. When parts to be polished with different sizes are replaced, the polishing process can be performed by loosening the screws for fixing the movable polishing positioning jig 231, pushing the movable polishing positioning jig 231, adjusting the mounting position of the movable polishing positioning jig 231 on the bearing base 210, and adjusting the distance from the abrasive belt 100 at the mounting position of the movable polishing positioning jig 231 to the surface to be polished of the workpiece.
Referring to fig. 1 and 2, the offset-adjusting tensioning mechanism 300 includes a wrench 310, a tension spring 320, a tensioning swing arm 330 and a spindle tensioning wheel 340, the tensioning wheel is rotatably disposed on the tensioning swing arm 330, the tensioning swing arm 330 and the wrench 310 are rotatably disposed on the bearing base, a gap is disposed between the tensioning swing arm 330 and the wrench 310, two ends of the tension spring 320 are respectively connected to the wrench 310 and the tensioning swing arm 330, the wrench 310 is used to drive the tension spring 320 to pull the tensioning swing arm 330 to swing when turning, and the tensioning swing arm 330 is used to drive the tensioning wheel to straighten the abrasive belt 100 when swinging. The wrench 310 is connected with the tension swing arm 330 through a tension spring 320, and the spindle tension wheel 340 is located between the driving wheel 220 and one of the driven guide wheels 230. In an operating state, a connection point of the wrench 310 and the tension spring 320 is located on a side far away from the tension swing arm 330, that is, the tension spring 320 is in a tension state, at this time, a large elastic force generated by the tension spring 320 pulls one end of the tension swing arm 330 connected to the tension spring 320 to move toward a direction close to the wrench 310, so that the tension swing arm 330 deflects, and the spindle tension wheel 340 struts the abrasive belt 100 while the tension swing arm 330 deflects, so that the abrasive belt 100 is kept in a tension state.
It will be appreciated that referring to fig. 1 and 2, abrasive belt 100, while polishing a workpiece to be polished, it is also worn, and belt 100 needs to be replaced when worn, simply by rotating wrench 310 in a direction closer to tensioning swing arm 330, since the connection portion of the wrench 310 and the tension spring 320 is close to the tension swing arm 330, the tension spring 320 contracts, the elastic force acting on belt from tensioning swing arm 330 becomes smaller, and spindle tensioner 340 acts on belt 100 not enough to tension belt 100, that is, abrasive belt 100 is in a loose state, so that a maintainer can easily remove a worn abrasive belt from abrasive belt group polishing structure 10, rewind new abrasive belt 100 around offset-adjusting tensioning mechanism 300, drive wheel 220 and driven guide wheels 230, reversely rotate wrench 310 to restore the original position, spindle tensioner 340 on tensioning swing arm 330 can be actuated to again spread belt 100 while belt 100 is under tension. Only the abrasive belt needs to be replaced, so that the operation difficulty is low.
Because the deviation-adjusting tensioning mechanism 300 for tensioning the abrasive belt 100 is a movable structure, the requirement of the abrasive belt group polishing structure 10 on the dimensional accuracy of the abrasive belt 100 is not high, the manufacturing cost of the abrasive belt 100 is reduced, and because the manufacturing cost of the abrasive belt 100 is far lower than that of a polishing wheel, the abrasive belt group polishing structure 10 is adopted to polish a workpiece to be polished, so that the polishing quality of the workpiece to be polished is improved, and the maintenance cost of equipment can be saved.
Further, referring to fig. 1 and fig. 2, in order to reduce the resistance of the abrasive belt 100 during polishing, a graphite layer is disposed on an outer sidewall of the movable polishing positioning fixture 231, the graphite layer is used for being attached to the abrasive belt 100, and the movable polishing positioning fixture 231 is smaller for the abrasive belt 100 when the abrasive belt 100 rotates due to the low surface roughness of the graphite layer.
Further, in order to improve the transmission capability of driving wheel 220, an anti-slip resin layer is disposed on the outer sidewall of driving wheel 220, thereby improving the friction between driving wheel 220 and abrasive belt 100 and reducing the occurrence of slip.
Further, in order to prevent the abrasive belt 100 from deviating during polishing and improve the positioning capability of the abrasive belt group polishing structure 10 on the abrasive belt 100, the spindle tension wheel 340 is provided with a drop-preventing area, the drop-preventing area is attached to the abrasive belt 100, the diameter of the spindle tension wheel 340 decreases from the two ends of the spindle tension wheel 340 to the middle position of the spindle tension wheel 340, the tensioning swing arm 330 includes a deviation-adjusting bottom plate and a deviation-adjusting block, a receiving groove is formed in a first end of the deviation-adjusting bottom plate, the deviation-adjusting block is received in the receiving groove, and the spindle tension wheel 340 is arranged on the deviation-adjusting block. The structural optimization of the spindle tension wheel 340 ensures that the abrasive belt 100 can be always positioned at the center position of the spindle tension wheel 340, and the phenomenon of falling off caused by the deviation force generated during polishing separating from the installation position can be avoided.
Compared with the prior art, the utility model discloses at least, following advantage has:
according to the abrasive belt group polishing structure 10, the abrasive belt 100, the polishing main body 200 and the deviation adjusting tensioning mechanism 300 are arranged, when a workpiece with a complex surface is polished, the polishing main body 200 is fixed on a multi-shaft polishing machine, the abrasive belt 100 on the polishing main body 200 is used for replacing a polishing wheel to polish the workpiece, the abrasive belt 100 is a flexible abrasive tool, the clamping and adjusting times of the multi-shaft polishing machine during polishing can be reduced, the polishing efficiency and the polishing precision are improved, the deviation adjusting tensioning mechanism 300 is used for tensioning the abrasive belt 100, the abrasive belt 100 can be replaced quickly through the deviation adjusting tensioning mechanism 300, and the maintenance cost is reduced.
