Description

Technical Field

[0001] The utility model relates to a sanding belt machine, in particular to a vertical sanding belt machine. Background Art

[0002] A belt sander is a device used to grind and polish objects. It can be divided into several categories, including desktop belt sanders, vertical belt sanders, hand-pushed belt sanders, and dust-removing belt sanders. Vertical belt sanders mainly use polishing materials such as cloth wheels, hemp wheels, thousand-leaf wheels, nylon wheels, and sanding belts. They are used for sanding, grinding, and polishing small and medium-sized hardware. Most of the existing object processing equipment has a relatively single processing function. After the initial processing of the object is completed, the object needs to be ground and polished. When grinding and polishing the object, the object is usually taken out of the machine tool and then placed on the grinding and polishing machine for grinding. When the machine tool is grinding and polishing the object, the object needs to be fixed on the grinding machine and the mounting position and angle are adjusted to complete the grinding of the object. Fixing the object before grinding will waste the operator's processing time, increase the operator's workload, prolong the production time of the object, and thus reduce the speed of the object production. In view of this, we propose a vertical belt sander. Utility Model Content

The rotating rotating frame changes the position of the adjusting wheel, and the circumferential surface of the adjusting wheel fits with the inner surface of the sanding belt.

[0006] As a further improvement of the present technical solution, the adjustment mechanism further includes an electric telescopic rod hinged to the outer surface of the shell near the middle position, one end of the electric telescopic rod is hinged to the outer surface of the rotating frame, and the working electric telescopic rod is used to drive the rotating frame to rotate.

[0007] As a further improvement of the present technical solution, the cleaning mechanism includes a mounting plate fixedly arranged on the outer surface of the shell near the bottom, a movable frame is slidably connected to the inside of the mounting plate, and a cleaning brush is fixedly arranged on the movable frame near one end of the grinding wheel. The cleaning brush is in contact with the outer surface of the sanding belt, and the cleaning brush is used to clean the rotating sanding belt.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. For this vertical belt sander, when the object is initially processed and needs to be processed later, the connecting frame, the indexing plate and the grinding mechanism are installed in sequence by bolts, and the object is ground by the grinding mechanism, so there is no need to remove the object for repositioning and installation, which shortens the object replacement time and improves the working efficiency of object grinding. When the grinding mechanism is grinding the object, the hand wheel is turned and the angle of the grinding mechanism is adjusted by the indexing plate, so that the object can be ground at different angles, further improving the grinding effect of the object.

[0012] 2. In the vertical sanding belt machine, when the sanding belt rotates and sands the object, the cleaning brush in contact with the sanding belt surface brushes off the debris attached to the sanding belt surface to prevent the sanding belt surface from becoming smooth due to excessive attachment of debris, which leads to a decrease in the sanding belt sanding effect. In addition, during the rotation of the grinding wheel, the transmission wheel in contact with the grinding wheel is driven to rotate, thereby driving the reciprocating screw to rotate. At the same time, during the rotation of the reciprocating screw, the movable frame and the cleaning brush are driven to move back and forth, thereby improving the cleaning effect of the cleaning brush on the sanding belt surface.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] See also Figure 1-Figure 7As shown, one of the purposes of this embodiment is to provide a vertical belt sander, including a machine tool spindle 1 and a grinding mechanism 2, the grinding mechanism 2 is used for grinding objects, the lower end of the machine tool spindle 1 is bolted with a connecting frame 11, and a dividing plate 12 is bolted on the connecting frame 11, and the rotating shaft of the dividing plate 12 is connected to a handwheel 121, and the grinding mechanism 2 includes a shell 21, and the shell 21 is bolted on the dividing plate 12. When different processing steps are required for the object, the connecting frame 11 is first installed on the lower end of the machine tool spindle 1 by bolts, and then the dividing plate 12 is installed on the connecting frame 11 by bolts, and finally, the shell 21 is installed on the turntable of the dividing plate 12 by bolts, thereby completing the installation of the grinding mechanism 2, shortening the object replacement time, improving the work efficiency of object grinding, and facilitating the subsequent use of the grinding mechanism 2.

[0028] When it is necessary to change the grinding angle of the grinding mechanism 2 on the object, the hand wheel 121 is held and turned, and the grinding mechanism 2 is driven to rotate through the dividing plate 12, thereby changing the grinding angle of the grinding mechanism 2 on the object, further improving the grinding effect of the grinding mechanism 2 on the object. To ensure the use of the grinding mechanism 2, a driving wheel 22 and a grinding wheel 23 are rotatably connected inside the shell 21. A motor 25 is fixedly provided on the outer surface of the shell 21 near the bottom. The output shaft of the motor 25 is coaxially connected to the driving wheel 22 through a coupling. The rotating output shaft of the motor 25 drives the driving wheel 22 to rotate. The outer sides of the driving wheel 22 and the grinding wheel 23 are connected with the sanding belt 24. When it is necessary to grind the object, the motor 25 works to drive the driving wheel 22 to rotate, and the sanding belt 24 is tightly fitted with the driving wheel 22 and the grinding wheel 23. During the rotation of the driving wheel 22, the sanding belt 24 and the grinding wheel 23 are driven to rotate, and the object is polished by the rotating grinding wheel 23 and the sanding belt 24.

[0029] During the process of the sanding belt 24 rotating and grinding the object, the debris generated by the grinding of the object adheres to the surface of the sanding belt 24, resulting in the smoothness of the uneven surface of the sanding belt 24 becoming larger, which makes the grinding efficiency of the sanding belt 24 lower. In order to ensure the grinding effect of the sanding belt 24 on the object, a cleaning mechanism 4 is provided on the shell 21. The cleaning mechanism 4 is used to clean the sanding belt 24. The cleaning mechanism 4 includes a mounting plate 41 fixedly arranged on the outer surface of the shell 21 near the bottom position, and a movable frame 42 is slidably connected to the inside of the mounting plate 41. The movable frame A cleaning brush 43 is fixedly provided near one end of the grinding wheel 23. The cleaning brush 43 is in contact with the grinding surface of the sand belt 24. The cleaning brush 43 is used to clean the rotating sand belt 24. During the rotation of the sand belt 24, the grinding surface of the sand belt 24 is in close contact with the cleaning brush 43, so that the residue attached to the grinding surface of the rotating sand belt 24 is cleaned by the cleaning brush 43, thereby avoiding the increase of the smoothness of the grinding surface of the sand belt 24 caused by the adhesion of the residue, and ensuring the normal use of the sand belt 24. At the same time, the cleaning mechanism 4 also includes a rotating connection at The mounting plate 41 is close to the transmission wheel 44 on the surface of the housing 21. The transmission wheel 44 is in close contact with the circumferential surface of the grinding wheel 23. The rotating grinding wheel 23 is used to drive the transmission wheel 44 to rotate. A reciprocating screw rod 45 is coaxially fixed to one end of the central axis of the transmission wheel 44. The movable frame 42 is threadedly connected to the reciprocating screw rod 45. The rotating reciprocating screw rod 45 drives the movable frame 42 to move back and forth. During the rotation of the grinding wheel 23 and the sanding belt 24, the grinding wheel 23 drives the transmission wheel 44 in close contact with the grinding wheel 23 to rotate, thereby The movable transmission wheel 44 drives the reciprocating screw 45 to rotate, and because the movable frame 42 is threadedly connected to the reciprocating screw 45, the movable frame 42 and the cleaning brush 43 are driven to move back and forth during the rotation of the reciprocating screw 45. The moving direction of the movable cleaning brush 43 is perpendicular to the rotation direction of the sanding belt 24. During the movement of the cleaning brush 43, the polishing surface of the sanding belt 24 is rubbed to clean away impurities on the sanding belt 24, thereby improving the cleaning effect of the cleaning brush 43 on the sanding belt 24 and ensuring the normal use of the sanding belt 24.

[0030] The abrasive belt 24 needs to be kept in a tensioned state during use. When the abrasive belt 24 needs to be replaced, it is difficult to remove the abrasive belt 24 in a tensioned state, which affects the replacement of the abrasive belt 24. In order to facilitate the replacement of the abrasive belt 24, an adjusting mechanism 3 is also provided on the shell 21. The adjusting mechanism 3 adjusts the tightness of the abrasive belt 24. The adjusting mechanism 3 includes a rotating frame 31 hinged to the outer surface of the shell 21 near the top position. A mounting rod 32 is bolted to the rotating frame 31. A through arc groove is opened on the side wall of the shell 21. One end of the mounting rod 32 passes through the arc groove. The mounting rod 32 is located inside the shell 21 and is rotatably connected to an adjusting wheel 33 at one end. The rotating rotating frame 31 changes the position of the adjusting wheel 33 so that the circumferential surface of the adjusting wheel 33 fits the inner surface of the abrasive belt 24. The adjusting mechanism 3 also includes an electric telescopic rod 34 hinged to the outer surface of the shell 21 near the middle position. One end of the electric telescopic rod 34 is hinged to the outer surface of the rotating frame 31. The rod 34 is used to drive the rotating frame 31 to rotate. When the sanding belt 24 needs to be replaced, the electric telescopic rod 34 works to drive the rotating frame 31 to rotate around the hinged position with the shell 21, thereby driving the mounting rod 32 and the adjusting wheel 33 to move toward the direction close to the grinding wheel 23, so that the adjusting wheel 33 does not tighten the sanding belt. At this time, the sanding belt 24 in the tensioned state becomes loose, making it easy for the operator to take the sanding belt 24 out of the shell 21, thereby facilitating the replacement of the sanding belt 24. After the old sanding belt 24 is removed, the new sanding belt 24 is put into the shell 21 so that the sanding belt 24 is sleeved on the driving wheel 22, the grinding wheel 23 and the outer side of the adjusting wheel 33. Subsequently, the electric telescopic rod 34 works to drive the rotating frame 31 to rotate, and the rotation of the rotating frame 31 drives the mounting rod 32 and the adjusting wheel 33 to move in the direction away from the grinding wheel 23, thereby tensioning the sanding belt 24 through the adjusting wheel 33 in cooperation with the driving wheel 22 and the grinding wheel 23, so that the subsequent sanding belt 24 rotates to grind the object.

[0031] In summary: when the object is initially processed and needs to be processed subsequently, first install the connecting frame 11 on the lower end of the machine tool spindle 1 by bolts, then install the dividing plate 12 on the connecting frame 11 by bolts, and finally install the shell 21 on the turntable of the dividing plate 12 by bolts, thereby completing the installation of the grinding mechanism 2. When the object needs to be polished, the motor 25 drives the driving wheel 22 to rotate, and the sanding belt 24 fits tightly with the driving wheel 22 and the grinding wheel 23. During the rotation of the driving wheel 22, the sanding belt 24 and the grinding wheel 23 are driven to rotate to polish the object. During the rotation of the sanding belt 24, the cleaning brush 43 is used to clean the residue attached to the grinding surface of the sanding belt 24, thereby avoiding the adhesion of the residue causing the smoothness of the grinding surface of the sanding belt 24 to increase and the grinding effect to decrease. At the same time, during the grinding During the rotation of the wheel 23 and the sanding belt 24, the grinding wheel 23 drives the transmission wheel 44 in close contact with the grinding wheel 23 to rotate, thereby driving the reciprocating screw rod 45 to rotate through the rotating transmission wheel 44, and during the rotation of the reciprocating screw rod 45, the movable frame 42 and the cleaning brush 43 are driven to reciprocate. The moving direction of the cleaning brush 43 is perpendicular to the rotation direction of the sanding belt 24, and the cleaning effect of the cleaning brush 43 on the sanding belt 24 is improved during the movement of the cleaning brush 43. When the sanding belt 24 needs to be replaced, the electric telescopic rod 34 drives the rotating frame 31 to rotate around the hinged position with the shell 21, thereby driving the mounting rod 32 and the adjusting wheel 33 to move toward the direction close to the grinding wheel 23, so that the sanding belt 24 in the tensioned state becomes loose, making it easy to take out the sanding belt 24 from the inside of the shell 21 for replacement.
