Detailed ways

The present utility model will be described in further detail below in conjunction with the accompanying drawings.

Example:

As shown in FIG. 1, a flat grinder with a dust removal device includes a frame 1, and a cover body 13 is slidingly connected to the frame 1 along the horizontal direction. The cover body 13 is provided with a worktable 11, and the worktable 11 passes through The magnetic plate 6 is adsorbed on the cover body 13 and slides left and right along with the cover body 13 . A grinding wheel 12 is connected to the frame 1 above the workbench 11 , and the setting direction of the grinding wheel 12 is perpendicular to the workbench 11 . A dust collecting hood 5 is fixedly connected to the frame 1 on one side of the grinding wheel 12 , and a blower 52 is connected to the dust collecting hood 5 through a suction pipe 51 . When the workpiece is processed, the grinding wheel 12 rotates toward the side of the dust collecting hood 5 , and the blower 52 is activated to extract most of the dust generated by grinding from the table 11 .

As shown in FIGS. 2 and 3 , a cleaning brush 4 is connected between the two side walls in the longitudinal direction of the cover body 13 . The bristles of the cleaning brush 4 are in contact with the upper surface of the table 11 . The worktable 11 moves in the longitudinal direction and cleans the particulate dust still attached to the worktable 11 that is not completely removed by the dust collecting hood 5 and the blower 52 . The drive assembly 2 includes a motor 21, a driving gear 22, a driven gear 23, and a chain 24 meshing with the driving gear 22 and the driven gear 23. The driving gear 22 and the driven gear 23 are respectively rotatably connected to the inner side of the side wall of the cover body 13, The motor 21 is installed on the outer side of the same side wall of the cover body 13 , and the rotor of the motor 21 is fixed coaxially with the driving gear 22 through the side wall of the cover body 13 , and the chain 24 is connected between the driving gear 22 and the driven gear 23 .

As shown in FIGS. 3 and 4 , the inner side of the side wall on the rear side of the cover body 13 is provided with a guide rail 3 along its length direction. The cleaning brush 4 is composed of two connecting rods 41 and a brush body 42 , and the brush body 42 is connected to the two connecting rods 41 and 42 . Between the connecting rods 41, and the length of the brush body 42 is equal to the width of the table 11, one of the connecting rods 41 is fixed above the chain 24 by welding, and the bottom end of the other connecting rod 41 is fixedly connected with a guide ring 411. 3 is embedded in the guide ring 411. The upper surface of the guide rail 3 is provided with a guide groove 31 along its length direction, and the guide ring 411 is embedded with a roller 412. When the guide rail 3 is located in the guide ring 411, the roller 412 is embedded in the guide groove 31, and the roller 412 guides along the guide groove 31. The groove 31 is rotated in the longitudinal direction.

After the flatness of the workpiece is polished, the grinding wheel 12 is lifted from the top of the workpiece, and the motor 21 is started. The motor 21 drives the chain 24 and the driven gear 23 to rotate. Since the connecting rod 41 on the side of the cleaning brush 4 is fixed above the chain 24, the cleaning brush 4 moves along the length direction of the workbench 11 together with the chain 24. Since the bristles of the cleaning brush 4 are in contact with the upper surface of the workbench 11, the cleaning brush 4 can be adsorbed on the workbench 11 during the movement along the length direction of the workbench 11. The dust on the upper surface is swept to one side. At the same time, due to the setting of the guide ring 411 of the guide rail 3, the movement process of the cleaning brush 4 is more stable. The setting of the roller 412 and the guide groove 31 effectively reduces the distance between the guide ring 411 and the guide rail 3. The friction force keeps the moving speed of both ends of the cleaning brush 4 synchronously. After the workpiece is polished, the cover body 13 is slid to the side perpendicular to the length direction and is located under the dust collecting cover 5, and the motor 21 is started to move the cleaning brush 4 to the bottom of the dust collecting cover 5, so that the cleaning brush 4 can clean it out. The dust is extracted from the workbench 11 by the blower 52 . It is difficult for the blower 52 to remove the complete dust, which is cleaned by the cleaning brush 4 and removed by the blower 52 again, which effectively reduces the workload of the staff in cleaning the workbench 11 . The driving gear 22 and the driven gear 23 are respectively arranged on the left and right sides of the table 11 perpendicular to the length direction, and the length of the guide rail 3 is equal to the distance between the driving gear 22 and the driven gear 23. When the grinding wheel 12 grinds the workpiece, The cleaning brush 4 is located on one side of the workbench 11 , and its bristles do not contact the upper surface of the workbench 11 .

As shown in FIG. 5 , the top ends of the two connecting rods 41 are provided with connecting grooves 413 , and a plurality of friction-increasing protrusions 414 are evenly fixed on the groove walls of the connecting grooves 413 . The friction-increasing protrusions 414 are made of rubber; the brush body 42 A connecting block 421 is integrally formed on the downward side. When the brush body 42 is arranged between the connecting rods 41 , the connecting block 421 is fitted into the connecting groove 413 . After a period of use, the bristles of the cleaning brush 4 may cause dust adhesion and bristles to be damaged and rolled up. At this time, the brush body 42 needs to be replaced, and the two ends of the old brush body 42 can be lifted up to remove the old brush body. 42 is removed, the same as the process of removing the brush body 42 , and a new brush body 42 is installed between the two connecting rods 41 . The friction-increasing protrusions 414 increase the stability of the connecting block 421 when it is located in the connecting groove 413, so that it is not easy to move.

The implementation principle of the above-mentioned embodiment is as follows: when the surface of the worktable 11 needs to be cleaned, the grinding wheel 12 is lifted, and the cover body 13 is moved to the end of the worktable 11 under the dust collecting cover 5, the motor 21 is started, and the cleaning brush 4 is The worktable 11 moves in the length direction, and the dust attached to the worktable 11 is cleaned to the bottom of the dust collecting hood 5. The blower 52 removes the dust from the worktable 11, makes the motor 21 reverse, and the cleaning brush 4 returns to its original position. next cleanup.

This specific embodiment is only an explanation of the present utility model, and it is not a limitation of the present utility model. Those skilled in the art can make modifications to the present embodiment without creative contribution as needed after reading this specification, but as long as the utility model is used in the present invention All new types of claims are protected by the patent law.
