DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the process of processing the steel plate, a burr removal device is needed. The burr removal device provided by the utility model can replace the grinding sleeve 7 during use, so there is no need to replace the entire grinding disc, avoiding waste of resources.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a steel plate edge burr removal device includes a workbench 1, a connecting frame 3 is fixed on the top of the workbench 1, a mobile frame 4 is slidably connected to the top of the connecting frame 3, a first telescopic rod 5 is slidably connected to the inner wall of the top of the mobile frame 4, a connecting piece 6 is fixed to the bottom end of the first telescopic rod 5, a rotating shaft is rotatably connected to the bottom end of the connecting piece 6, a fixing piece 12 is fixed to the bottom end of the rotating shaft, a grinding sleeve 7 is plugged into the outer wall of the fixing piece 12, a slot 13 is provided at the top of the grinding sleeve 7, the fixing piece 12 is plugged into the slot 13, connecting slots 14 are provided on both sides of the inner walls of the slot 13, two mounting slots 21 are provided inside the fixing piece 12, the mounting slots 21 are located on both sides of the rotating shaft, and the two mounting slots 21 are opposite to each other. A sliding groove 22 is provided on the side away from each other, and an extrusion block 18 is slidably connected in the installation groove 21. The extrusion block 18 is a right-angled trapezoid. A moving block 19 is slidably connected in the sliding groove 22. One side of the moving block 19 contacts the inclined side of the extrusion block 18. A limiting block 15 is fixed on the side of the moving block 19 away from the extrusion block 18. The limiting block 15 penetrates the fixing member 12 and is inserted in the connecting groove 14. A spring 20 is fixed between the moving block 19 and the inner wall of the sliding groove 22. The top of the fixing member 12 is located on both sides of the rotating shaft and is screwed with screws 17. The screw 17 is rotatably connected to the extrusion block 18. Two connecting sleeves 16 are fixed to the top of the fixing member 12. The screw 17 is screwed in the connecting sleeve 16, and a knob is fixed on the top of the screw 17.

[0021] It should be noted that when the grinding sleeve 7 needs to be disassembled, the screw 17 is rotated, and the screw 17 drives the extrusion block 18 to move upward, so that the moving block 19 is moved in the direction close to the extrusion block 18 under the action of the spring 20, so that the limit block 15 is no longer inserted into the connecting groove 14, which facilitates the disassembly of the grinding sleeve 7. In this way, only the grinding sleeve 7 needs to be replaced. In addition, when the replaced grinding sleeve 7 needs to be installed, it is only necessary to align the grinding sleeve 7 with the outer wall of the fixing part 12 and insert it. After insertion, the screw 17 is rotated in the opposite direction, and the screw 17 drives the extrusion block 18 to move downward, thereby squeezing the moving block 19, so that the limit block 15 is inserted into the connecting groove 14, and the grinding sleeve 7 is limited and fixed.

[0022] like Figure 2 As shown, the top of the workbench 1 is rotatably connected with a rotating rod 8, the bottom of the workbench 1 is fixed with a first motor, the output end of the first motor passes through the workbench 1 and is fixed to the rotating rod 8, the top of the rotating rod 8 is fixed with a supporting plate, the top of the workbench 1 is fixed with a supporting frame 2, the top inner wall of the supporting frame 2 is fixed with a second telescopic rod 9, and the telescopic end of the second telescopic rod 9 is rotatably connected with an extrusion plate 10. A dust cover 11 is fixed to one side of the mobile frame 4, a collection box 23 is fixed to one side of the supporting frame 2, a dust collection pipe is fixedly connected between one end of the collecting box 23 and the dust cover 11, a fan 25 is installed at the other end of the collecting box 23, the air inlet of the fan 25 is connected to the collecting box 23, a collecting box 24 is inserted in the collecting box 23, and a filter is fixed in the collecting box 24. A second motor is fixed in the connecting member 6, and the output end of the second motor passes through the connecting member 6 and is fixed to the rotating shaft. A controller is fixed to the other side of the supporting frame 2, and the controller is electrically connected to the first motor, the second motor and the fan 25.

[0023] It should be noted that the rotating rod 8 is driven to rotate by the first motor, and a steel plate is placed on the top of the support plate. The steel plate is squeezed between the extrusion plate 10 and the support plate. The rotation of the rotating rod 8 can drive the steel plate to rotate, thereby facilitating the grinding of different positions of the steel plate. In addition, the dust generated during the grinding process is sucked away by the fan 25, sent into the collection box 23, and filtered by the filter.

[0024] Working principle: When the grinding sleeve 7 needs to be disassembled, the screw 17 is rotated, and the screw 17 drives the extrusion block 18 to move upward, so that the moving block 19 moves toward the extrusion block 18 under the action of the spring 20, so that the limit block 15 is no longer inserted into the connecting groove 14, which facilitates the disassembly of the grinding sleeve 7.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
