DETAILED DESCRIPTION

The telescopic member 11 is slidably connected to the limit block 14, and a plurality of thread grooves are evenly opened on the telescopic member 11. The bolt 12 is threadedly connected to the telescopic member 11, and the round rod 13 is slidably connected to the lower right side of the telescopic member 11. The round rod 13 and the limit holes on the limit block 14 are both snap-fitted. The dual-axis motor 15 is connected to the upper left side of the telescopic member 11, and a grinding rod 16 is snap-fitted on the output shaft on the rear side of the dual-axis motor 15. A fixing mechanism 2 is provided on the base 1, and the fixing mechanism 2 is used to fix sheet metal chassis of different specifications. A rotating mechanism 3 is provided on the fixing mechanism 2, and the rotating mechanism 3 is used to rotate the sheet metal chassis and change sides.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, the fixing mechanism 2 includes a disc 21, an extrusion piece 22, a first spring 23 and a connecting rod 24. The connecting rod 24 is rotatably connected to the upper side of the rear part of the base 1, and the disc 21 is connected to the front side of the connecting rod 24. Four extrusion pieces 22 are evenly and slidably connected to the disc 21 along the circumferential direction. The side of the extrusion piece 22 close to the center direction of the disc 21 is made of soft material. A first spring 23 is wound between the extrusion piece 22 and the disc 21. The first springs 23 are all wound on the adjacent extrusion pieces 22. The first springs 23 cooperate with the corresponding extrusion pieces 22 to clamp and fix sheet metal chassis of different specifications.

[0033] like Figure 1 and Figure 5As shown, the rotating mechanism 3 includes a first ratchet 31, a handle 32, a first fixed frame 33, a pawl 34, a pull rope 35 and a ring 36. The first ratchet 31 is connected to the rear side of the connecting rod 24, and the handle 32 is also connected to the rear side of the connecting rod 24. The left and right sides of the upper rear part of the base 1 are connected to the first fixed frame 33, and the pawls 34 are rotatably connected to the upper rear side of the first fixed frame 33. The pawls 34 are squeezed and fitted with the first ratchet 31. Two rings 36 are connected to the upper rear side of the first fixed frame 33 on the right, and a pull rope 35 is connected to the upper left side of the right pawl 34. The other end of the pull rope 35 passes through the two rings 36. By rotating the handle 32, the connecting rod 24 drives the disc 21 to rotate, so that people can easily rotate and change sides of the sheet metal chassis.

[0034] In the initial state, the round rod 13 is inserted into the limiting hole on the rear side of the limiting block 14, and the pawls 34 on the left and right sides both clamp the first ratchet 31. The sheet metal can be made into a square frame-shaped sheet metal chassis, and the four edges of the height of the sheet metal chassis need to be polished and trimmed. When using the sheet metal trimming device that can be applied to various specifications to polish and trim the sheet metal chassis, first pull out the round rod 13 to the right, so that the round rod 13 is away from the limiting hole on the current limiting block 14, and then move the telescopic part 11 forward to drive the bolt 12, the dual-axis motor 15 and the polishing rod 16 to move forward, so that the polishing rod 16 is away from the disc 21, and then move the extrusion part 22 to the side away from the center direction of the disc 21, the first spring 23 is compressed, and then the sheet metal chassis that needs to be polished and trimmed is placed on the four The position between the extrusion pieces 22 is adjusted, and the opening of the sheet metal chassis is facing backward, that is, the bottom surface of the sheet metal chassis is ahead. The extrusion piece 22 is released, and the extrusion piece 22 will move back and reset under the action of the corresponding first spring 23 until the extrusion piece 22 can no longer move under the obstruction of the sheet metal chassis. Since the side of the extrusion piece 22 close to the center direction of the disc 21 is made of soft material, the side of the extrusion piece 22 close to the center direction of the disc 21 will be appropriately compressed and deformed when it contacts the sheet metal chassis, so that the extrusion piece 22 can clamp the sheet metal chassis more closely, and the first spring 23 will also apply an extrusion force to the corresponding extrusion piece 22, so that the extrusion piece 22 can clamp the sheet metal chassis more tightly, so that the extrusion piece 22 can clamp and fix the sheet metal chassis of different specifications. The sheet metal chassis is convenient for people to grind and trim sheet metal chassis of different specifications. Then people can choose the grinding rod 16 of appropriate length according to the height of the sheet metal chassis. When the grinding rod 16 needs to be replaced, the existing grinding rod 16 on the dual-axis motor 15 is pulled out, and then a new grinding rod 16 of appropriate length is clamped on the output shaft on the rear side of the dual-axis motor 15, and then the position of the telescopic member 11 and the grinding rod 16 is adjusted according to the size of the sheet metal chassis. The telescopic member 11 can be moved backward to reset, so that the bolt 12, the dual-axis motor 15 and the grinding rod 16 are also moved backward to reset, so that the grinding rod 16 is close to the sheet metal chassis, and then it is rotated and moved forward to take out the bolt 12, and the length of the upper left side of the telescopic member 11 is appropriately adjusted so that the dual-axis motor 15 and The grinding rod 16 moves to the upper left side until the grinding rod 16 can roughly contact the edge of the upper left side of the sheet metal chassis, and then continues to move the telescopic part 11 backward to reset, so that the bolt 12, the dual-axis motor 15 and the grinding rod 16 also continue to move backward to reset, until the grinding rod 16 can contact the edge of the upper left side of the sheet metal chassis, at this time, the bolt 12 can be aligned with the corresponding thread groove on the telescopic part 11, and the bolt 12 is rotated in the opposite direction, so that the bolt 12 moves backward and is stuck in the corresponding thread groove on the telescopic part 11, so as to lock the telescopic part 11, so that the grinding rod 16 can be more stable, and then the round rod 13 is inserted into the telescopic part 11, so that the round rod 13 is stuck in the corresponding limit hole to prevent the telescopic part 11 from sliding, and the dual-axis motor 15 can be started at this time.The output shaft at the rear side of the dual-axis motor 15 rotates, driving the grinding rod 16 to rotate, so that the edge of the upper left side of the sheet metal chassis can be polished and trimmed by the grinding rod 16. When the edge of the upper left side of the sheet metal chassis is polished and trimmed, the dual-axis motor 15 temporarily stops working, and the left pawl 34 is in the initial state and cannot continue to rotate clockwise, and the right pawl 34 is in the initial state and cannot continue to rotate counterclockwise. At this time, the first ratchet 31 cannot rotate, and people need to pull the right end of the pull rope 35 downwards to make The pull rope 35 pulls the right pawl 34, causing the right pawl 34 to rotate clockwise at the initial position, so that the right pawl 34 no longer blocks the first ratchet 31, and then people can rotate the connecting rod 24 clockwise through the handle 32, driving the first ratchet 31 to rotate, so that the disc 21 and the extrusion piece 22 rotate accordingly, and the sheet metal chassis also rotates, so that the sheet metal chassis can rotate and change sides. When the next edge of the sheet metal chassis that needs to be polished and trimmed contacts the polishing rod 16, the pull rope 35 is released, and the right side The pawl 34 will rotate in the opposite direction and reset under the action of its own gravity, that is, the right pawl 34 will rotate back to the initial state. At this time, the right pawl 34 cannot rotate counterclockwise, so that the right pawl 34 clamps the first ratchet wheel 31 again, so that the first ratchet wheel 31 cannot rotate again, that is, the disc 21 and the extrusion piece 22 cannot rotate anymore, so that the sheet metal chassis can be more stable, and then referring to the above steps, the grinding rod 16 is rotated to grind and trim the next edge of the sheet metal chassis, so that It is convenient for people to gradually complete the grinding and trimming work on the sheet metal chassis, so that it is also convenient for people to use the sheet metal trimming device applicable to various specifications to grind and trim sheet metal chassis of different specifications. After the grinding and trimming of the sheet metal chassis is completed, the dual-axis motor 15 is turned off, and the sheet metal chassis with completed grinding and trimming is taken out. When the extrusion member 22 is away from the sheet metal chassis, the extrusion member 22 will move to the side close to the center direction of the disc 21 under the action of the corresponding first spring 23 and reset. In summary, the grinding and trimming work of the sheet metal chassis can be completed.

[0035] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 6 and Figure 7As shown, it also includes a water spray dust reduction mechanism 4, which includes a second ratchet 41, a first wedge frame 42, a liquid outlet box 43, a second spring 44, a liquid outlet pipe 45, a piston 46, a liquid inlet pipe 47, a bucket 48 and an atomizing nozzle 49. The left side of the upper rear part of the base 1 is rotatably connected with the second ratchet 41, the second ratchet 41 is meshed with the first ratchet 31, and the front side of the second ratchet 41 is evenly connected with a plurality of extrusion columns along the circumferential direction. The upper side of the left rear part of the base 1 is connected with the liquid outlet box 43, the first wedge frame 42 is slidably connected to the liquid outlet box 43, the first wedge frame 42 and the extrusion columns are both extrusion-matched, the first wedge frame 42 is connected with a piston 46, the piston 46 is slidably connected to the liquid outlet box 43, a second spring 44 is wound between the left side of the piston 46 and the inner left side of the liquid outlet box 43, and the second spring 44 is wound between the left side of the piston 46 and the inner left side of the liquid outlet box 43. The spring 44 is wound around the first wedge-shaped frame 42, the liquid outlet pipe 45 is connected to the upper left side of the liquid outlet box 43, the liquid outlet pipe 45 is communicated with the liquid outlet box 43, a one-way valve is connected to the rear lower side of the liquid outlet pipe 45, the one-way valve is communicated with the liquid outlet pipe 45, a water bucket 48 is connected to the left rear side of the upper part of the base 1, a liquid inlet pipe 47 is connected to the water bucket 48, the liquid inlet pipe 47 is communicated with the water bucket 48, the liquid inlet pipe 47 is also communicated with the liquid outlet box 43, a one-way valve is connected to the rear upper side of the liquid inlet pipe 47, the one-way valve is communicated with the liquid inlet pipe 47, an atomizing nozzle 49 is connected to the lower right side of the front part of the liquid outlet pipe 45, the atomizing nozzle 49 is communicated with the liquid outlet pipe 45, the water in the liquid outlet box 43 is squeezed by the piston 46, so that it can be transported to the atomizing nozzle 49 through the liquid outlet pipe 45, so that the atomizing nozzle 49 can spray water mist, thereby spraying dust reduction and preventing dust from being raised.

[0036] In the initial state, the water bucket 48 and the liquid outlet box 43 are both filled with water. When the sheet metal chassis is polished and trimmed, dust will be generated, which may affect people's polishing and trimming of sheet metal chassis of different specifications. When the first ratchet 31 rotates, under the action of the first ratchet 31, the second ratchet 41 rotates, driving the extrusion column to rotate. When the extrusion column rotates to contact the first wedge frame 42, it will squeeze the first wedge frame 42 to the left, driving the piston 46 to move to the left. The second spring 44 is compressed, and the piston 46 will squeeze the water in the liquid outlet tank 43. Under the action of the one-way valve on the liquid inlet pipe 47, the water in the liquid outlet pipe 45 will not flow into the liquid inlet pipe 47 at this time, so that the water in the liquid outlet tank 43 can be squeezed and transported into the liquid outlet pipe 45, and transported to the atomizing nozzle 49 through the liquid outlet pipe 45, and from the atomizing nozzle Water mist is sprayed from the head 49. When the extrusion column rotates away from the first wedge frame 42, the piston 46 will move to the right and reset under the action of the second spring 44, driving the first wedge frame 42 to move and reset accordingly. In this way, the water in the water bucket 48 can be drawn through the piston 46 and the liquid inlet pipe 47, so that the water can be replenished in the liquid inlet and outlet tank 43. Under the action of the one-way valve on the liquid outlet pipe 45, the water in the liquid outlet pipe 45 will not be drawn back into the liquid outlet tank 43, and the second ratchet 41 will continue to drive the extrusion column to rotate. When the next extrusion column rotates to contact the first wedge frame 42, the above steps will be repeated. In this way, the polished and trimmed area can be continuously sprayed to reduce dust and avoid dust from being raised, so that people can polish and trim sheet metal chassis of different specifications through the sheet metal trimming device that can be applicable to various specifications.

[0037] like Figure 1 and Figure 8 As shown, a reinforcing mechanism 5 is also included, and the reinforcing mechanism 5 includes a second fixing frame 51, a reinforcing member 52 and a third spring 53. The second fixing frame 51 is connected to the left rear side of the telescopic member 11, and the reinforcing member 52 is slidably connected to the second fixing frame 51. The reinforcing member 52 is used to further clamp and fix the sheet metal chassis to make it more stable. The third spring 53 is wound between the upper and lower sides of the reinforcing member 52 and the second fixing frame 51, and the third spring 53 is wound around the reinforcing member 52.

[0038] When the sheet metal chassis rotates, the extrusion piece 22 may not be able to clamp the sheet metal chassis firmly, causing the sheet metal chassis to fall down, affecting people's subsequent grinding and trimming work. Therefore, when people clamp and fix the sheet metal chassis, they first move the reinforcement piece 52 forward, the third spring 53 is compressed, and then the sheet metal chassis is clamped and fixed between the four extrusion pieces 22. At this time, the sheet metal chassis will be located between the disc 21 and the reinforcement piece 52. Release the reinforcement piece 52, and the reinforcement piece 52 will move backward and reset under the action of the third spring 53 until the reinforcement piece 52 can no longer move backward due to the obstruction of the sheet metal chassis. In this way, the sheet metal chassis can be clamped front and back by cooperating with the disc 21, and the third spring 53 will apply a backward extrusion force to the reinforcement piece 52. The pressure force enables the reinforcement 52 to clamp sheet metal chassis of different specifications more tightly, and when people adjust the position of the telescopic member 11 according to the size of the sheet metal chassis, the second fixing frame 51 and the reinforcement 52 will move along with the telescopic member 11, so that the reinforcement 52 can better clamp sheet metal chassis of different specifications. This makes it easier for people to use the sheet metal trimming device that can be applied to a variety of specifications to grind and trim sheet metal chassis of different specifications. When the grinding and trimming of the sheet metal chassis is completed, move the reinforcement 52 forward again, and the third spring 53 is compressed, so that the reinforcement 52 is away from the sheet metal chassis, making it easier for people to take it out, and then release the reinforcement 52, and the reinforcement 52 will move backward and reset under the action of the third spring 53.

[0039] like Figure 1 and Fig. 9 As shown, a protective mechanism 6 is also included, and the protective mechanism 6 includes a protective shell 61, a movable plate 62, a roller 63 and a slide rail 64. The protective shell 61 is connected to the upper side of the base 1, and the protective shell 61 is made of a transparent material. The slide rail 64 is connected to the right side of the upper part of the base 1. The movable plate 62 is slidably connected to the right side inside the protective shell 61. The movable plate 62 is also made of a transparent material. The front and rear sides of the lower part of the movable plate 62 are rotatably connected with rollers 63. The rollers 63 are in contact with the slide rail 64, and the polished and trimmed sheet metal chassis is shielded by the protective shell 61 and the movable plate 62 to prevent it from suddenly collapsing and accidentally injuring people.

[0040] When grinding and trimming the sheet metal chassis, the sheet metal chassis may suddenly collapse, which may accidentally injure people nearby. Therefore, a protective shell 61 is set. When people clamp and fix the sheet metal chassis and need to start grinding and trimming, they first move the movable plate 62 backwards, so that the roller 63 also moves backwards. The roller 63 will rotate under the action of friction, so that it is easier to move the movable plate 62. In this way, the movable plate 62 can cooperate with the protective shell 61 to surround and shield the sheet metal chassis, thereby preventing it from suddenly collapsing and accidentally injuring people. It plays a protective role for people, which is also conducive to people to better grind and trim sheet metal chassis of different specifications. Since the protective shell 61 and the movable plate 62 are made of transparent materials, it will not affect people's viewing of the real-time status of the sheet metal chassis, that is, it will not affect people's grinding and trimming work. When the sheet metal chassis needs to be taken out after grinding and trimming, the movable plate 62 is slid forward to reset, and the roller 63 is driven to move forward and reset. The roller 63 will rotate in the opposite direction under the action of friction. At this time, people can take out the sheet metal chassis that has been polished and trimmed from the right side of the protective shell 61.
