[0002] Columnar wood sanding and polishing device is a common wood processing device designed to improve the smoothness and surface quality of columnar wood.
[0003] In the prior art, when sanding cylindrical wood, it is usually necessary to first use a large sanding disc to quickly rough-process the wood surface, and then switch to a small sanding disc to fine-process the wood surface, so as to avoid excessive sanding of the wood, which makes the obtained wood diameter lower than the required specifications. The working steps are cumbersome and the convenience is low. At the same time, when fine-processing the wood, it is often necessary to synchronously adjust the rotation speed of the sanding disc to facilitate further fine sanding of the wood, thereby avoiding insufficient sanding effect. Therefore, a device is needed that can automatically switch the size of the sanding end according to the diameter of the wood and change the rotation speed of the sanding end at the same time to avoid low convenience and insufficient sanding effect.

[0026] The use method and advantages of the present invention: A grinding and polishing device for processing cylindrical wood, the working process is as follows: like Figures 1 to 15 As shown, by controlling the driving motor 44 to work, the driving bevel gear 43 is driven to rotate, and then the two linked bevel gears 46 are driven to rotate in opposite directions, so that the two gear rings 45 are rotated in opposite directions. Under the action of one of the gear rings 45, the meshing sleeve 51 engaged therewith is driven to synchronously drive the driving rod 47 and the driving threaded rod 48 to rotate synchronously. Under the action of the driving threaded rod 48 and the matching ring 60, the matching ring 60 and the sliding ring 58 are driven to move in the direction of the limiting rod 57. Whenever the side end of the sliding ring 58 moves to the side end of one of the compression springs 62, the compression spring 62 is used to press the side end of the sliding ring 58 to move the limiting rod 57. The reverse resistance provided by the spring 62 causes the driving threaded rod 48 and the driving rod 47 to slide on the driving plate 41, and through the rotating sleeve 49, the contact ball 56 is embedded in the adjacent annular groove 52 under the cooperation of the limiting spring 55 and the sliding rod 54, thereby ensuring the stability of the sliding process of the driving threaded rod 48. After the driving threaded rod 48 slides, the engaging sleeve 51 is driven to engage with the other gear ring sleeve 45, thereby driving the connecting frame 63 to move in the opposite direction, thereby facilitating the automatic reciprocating movement of the connecting frame 63, facilitating the grinding and polishing work, and further improving the convenience in work; When the drive motor 44 is working, the first transmission belt 74 is provided, thereby synchronously driving the transmission shaft 72 and the linkage plate 73 to rotate, and through the provided L-shaped rod 75, the other linkage plate 73 is driven to rotate. Under the action of the second transmission belt 76, the control shaft 77 is driven to rotate synchronously, so that the speed change roller 83 rotates synchronously. Since the speed change roller 83 abuts on the matching sleeve 87, when the connecting frame 63 drives the matching sleeve 87 to move synchronously back and forth, it can synchronously drive the matching sleeve 87 to slide along the moving rod 84, thereby driving the matching sleeve 87 to move along the surface of the speed change roller 83, so that the shaft sleeve 85 and the brake bevel gear 88 rotate accordingly. When the distance from the cylindrical wood is far away, the matching sleeve 87 abuts against the side with a shorter diameter of the speed change roller 83, and vice versa, it abuts against the side with a longer diameter of the speed change roller 83, so that the brake bevel gear 88 can provide different speeds according to the distance between the grinding disc and the workpiece, further facilitating fine grinding and improving the grinding effect. When the connecting frame 63 moves to a position closer to the workpiece, it can synchronously drive the synchronous frame 91 to move, so that after it moves into place, the side end of the meshing bevel gear 92 meshes with the bottom of the passive bevel gear 93, and the side end of the meshing bevel gear 92 is synchronously meshed with the control bevel gear 95. Under the action of the third transmission belt 94, the control bevel gear 95 synchronously drives the control disk 96 to rotate. When the toggle rod 104 contacts the end of the tilting rod 102, it can drive the tilting rod 102 and the oblique block 103 away from the control wedge block 101, so that under the action of the first spring telescopic rod 100, the locking rod 97 slides along the card plate 99 through the through groove 98, thereby driving the spring claw 107 to be clamped in the side end of the meshing sleeve 51. The end of the L-shaped spring rod 108 abuts against the side end of the spring claw 107, so that the engaging sleeve 51 cannot complete the switching work, thereby allowing the grinding disc to finely grind for a period of time when it is close to the workpiece, and after the control plate 96 drives the abutting rod 106 to contact the reset wedge block 105, during the rotation process, the spring claw 107 is pulled away from the driving rod 47, and the first spring telescopic rod 100 is synchronously charged, and the inclined surface of the control wedge block 101 cooperates with the inclined surface of the oblique block 103, so that the control wedge block 101 abuts against the side end of the oblique block 103 again, and is locked in position by the tilting rod 102, thereby facilitating the next work and improving the convenience of using the device; During the rotation of the braking bevel gear 88, the switching bevel gear 1121 meshing with it will be driven to rotate synchronously, thereby driving the release bevel gear 1122 to rotate, so that the grinding piece 12 can rotate synchronously. The initial state of the grinding piece 12 is a vertical state, so that the outer side of the workpiece can be ground and polished by the side end with a longer diameter of the conical bottom of the grinding piece 12. When the connecting frame 63 drives the matching sleeve 87 to move to a certain distance toward the workpiece, it can contact one side of the square frame 1112 through the trigger rod 1111, and under the action of the second spring telescopic rod 1113, the grinding piece 12 can rotate synchronously. By sliding downward, the connecting shaft 1115 is driven to slide along the connecting groove 1117, and the toggle frame 1116 is driven to deflect along the center axis 1118 synchronously, thereby driving the switching frame 1123 to deflect synchronously, so that the release bevel gear 1122 and the grinding piece 12 are deflected synchronously, so that the side of the grinding piece 12 with a shorter diameter contacts the surface of the workpiece, and with the moving distance, the diameter of the side of the grinding piece 12 contacting the workpiece gradually becomes smaller, thereby avoiding excessive grinding of the wood and making the obtained wood diameter lower than the required specification, simplifying the working steps and improving convenience.
