Abstract
A revolving body surface grinding device for an abrasive belt grinding machine comprises a bearing, a shaft, a connecting frame, a belt wheel, a synchronous belt, a speed reduction motor, a gear, a revolving support and a bottom plate. The shaft is connected with the bearing, the connecting frame and the belt wheel, the synchronous belt is externally meshed with the belt wheel, the speed reducing motor and the bottom plate are arranged on the connecting frame, the rotary support is arranged on the bottom plate, the gear is connected with the shaft of the speed reducing motor, and the gear is internally meshed with the rotary support. The gear is driven by the speed reducing motor to rotate, and the gear is in inner meshing transmission with the rotary support, namely, the rotary body arranged on the surface of the rotary support can rotate along with the rotation of the rotary support. The synchronous belt drives the belt wheel to rotate under the driving of the power source, and the belt wheel drives the shaft to rotate, so that the connecting frame rotates together. Therefore, the revolving body can rotate around a certain central line, and the purpose of grinding the surface of the revolving body is achieved.
Description
Technical Field
The utility model belongs to the technical field of the abrasive band is polished, a solid of revolution surface grinding device for abrasive band grinding machine is related to.
Background
The existing tool matched with abrasive belt grinding equipment cannot enable a revolving body workpiece (such as a cylindrical workpiece, an elliptical workpiece, a spherical workpiece and the like) to rotate around a certain central line, so that the surface of the workpiece cannot be ground, the improvement of the grinding equipment technology is seriously influenced, and the development of a grinding process is hindered.
SUMMERY OF THE UTILITY MODEL
The problem on the surface of this kind of work piece can't be polished to the unable solid of revolution work piece (like cylindrical work piece, oval work piece and spherical work piece etc.) round its central rotation of frock for overcoming current cooperation abrasive band equipment of polishing, the utility model provides a solid of revolution surface grinding device for abrasive band grinding machine, the device install on the frame of equipment, can make the solid of revolution rotatory round certain central line to reach the mesh of polishing the solid of revolution surface.
The utility model discloses the technical scheme who adopts:
a revolving body surface grinding device for an abrasive belt grinding machine comprises a bearing, a shaft, a connecting frame, a belt wheel, a synchronous belt, a speed reduction motor, a gear, a revolving support and a bottom plate. The shaft is connected with the bearing, the connecting frame and the belt wheel, the synchronous belt is externally meshed with the belt wheel, the speed reducing motor and the bottom plate are arranged on the connecting frame, the rotary support is arranged on the bottom plate, the gear is connected with the shaft of the speed reducing motor, and the gear is internally meshed with the rotary support.
In order to further realize the utility model discloses the purpose, saddle type bearing is chooseed for use to the bearing, and servo gear motor and area brake braking are chooseed for use to gear motor, and the hold-in range is with the band pulley external toothing transmission, guarantees that the transmission is steady, do not have the slip.
Preferably, the inner ring of the rotary support is toothed and is in inner meshing transmission with the gear, so that the transmission efficiency is high and the bearing capacity is strong.
The utility model has the advantages as follows:
1. the bearing is a saddle bearing, which has both the aligning function and the direct fixation, and can adjust the deviation of the axis caused by the deflection, the eccentricity and the like of the shaft, so that the abnormal load can not act on the bearing, thereby ensuring the service life of the bearing.
2. The speed reduction motor selects the servo speed reduction motor with the brake, so that the rotary support can be guaranteed to rotate randomly, the stability of the rotary support when the speed reduction motor does not work can be guaranteed, workers can be prevented from being bruised by the rotation of the part connected with the rotary support after power failure, and the safety of the workers is effectively guaranteed.
3. The synchronous belt transmission has the characteristics of stable transmission, no sliding, low noise and the like.
4. The inner ring of the rotary support is provided with teeth, and is in inner meshing transmission with the gear, so that the rotary support has the characteristics of high transmission efficiency, strong bearing capacity and the like.
Drawings
The present invention will be further explained with reference to the accompanying drawings:
fig. 1 is a schematic structural view of a revolving body surface grinding device for a belt grinder of the present invention.
Fig. 2 is a schematic structural view of a belt sander.
FIG. 1 shows a bearing; 2. a shaft; 3. a connecting frame; 4. a pulley; 5. a synchronous belt; 6. a reduction motor; 7. a gear; 8. a rotary support; 9. a base plate; 10. a grinding device for the surface of a revolving body of a belt grinder.
Detailed Description
Referring to fig. 1, bearing 1 selects saddle type bearing for use, on the frame of direct mount abrasive belt grinding machine, and has the aligning function, axle 2 is connected with bearing 1, link 3 and band pulley 4, and hold-in range 5 and band pulley 4 external toothing, when starting external power source, hold-in range 5 takes band pulley 4 to rotate together under the drive of external power source, and band pulley 4 takes axle 2 to rotate to make link 3 make a round trip to overturn around the central line of axle 2.
The speed reducing motor 6 and the bottom plate 9 are arranged on the connecting frame 3, the rotary support 8 is arranged on the bottom plate 9, and the gear 7 is connected with the shaft of the speed reducing motor 6. When the speed reducing motor 6 is electrified, the speed reducing motor 6 starts to rotate, the speed reducing motor 6 drives the gear 7 to rotate, and the gear 7 drives the rotary support 8 to rotate together due to the fact that the inner ring of the rotary support 8 is provided with teeth and is in internal meshing transmission with the gear 7, and therefore the rotary body arranged on the surface of the rotary support 8 can rotate along with the rotation of the rotary support 8.
Thus, the revolving body can rotate around the central line of the shaft 1 and the central line of the revolving support 8, thereby achieving the purpose of grinding the surface of the revolving body.
