[0002] In the field of mining machinery manufacturing, vertical milling machine chamfering fixtures, as key processing equipment, undertake the important task of accurately chamfering workpieces. However, traditional mining machinery vertical milling machine chamfering fixtures face a series of technical problems in practical applications, which need to be solved urgently. First, during the cutting process, spark splashing and metal powder diffusion are common safety hazards. These flying sparks and powders may not only cause harm to operators, but also pollute the working environment and affect the normal operation of the equipment. Therefore, how to optimize the cutting environment and reduce spark splashing and metal powder diffusion has become a technical problem that needs to be solved urgently. Secondly, with the continuous improvement of mining machinery's requirements for workpiece chamfering accuracy and processing efficiency, traditional fixtures are often difficult to meet diverse processing needs.

[0029] Example

[0030] Reference Figure 1-Figure 7 A chamfering tool for a mining mechanical vertical milling machine includes a stable workbench 1. A discharge plate 2 for placing a workpiece to be processed is installed on the top of the workbench 1. In order to protect the operator and collect the generated debris during the work process, a movable shielding cover 3 is set on one side of the discharge plate 2, and the shielding cover 3 is equipped with a cabinet door for easy operation. A cutting part 4 is installed inside the shielding cover 3 for chamfering the workpiece. In addition, a movable push plate 5 is installed on the top of the discharge plate 2, and a hydraulic rod 6 is installed on the push plate 5 for clamping the workpiece to ensure stable processing. The workbench 1 is provided with a driving part 7 at the bottom of the shielding cover 3 for controlling the movement of the shielding cover 3. A movable shielding plate 31 is also designed on the side of the shielding cover 3, which can be adjusted according to the size of the workpiece. In order to cool the cutting part 4, a liquid storage box 32 is installed on the inner top wall of the shielding cover 3, and the liquid storage box 32 is connected to the liquid spray head 322 through a hose 321, and the liquid spray head 322 is directly aimed at the cutting position. At the same time, a motor 21 is installed on the workbench 1, and its output end is connected to a rotating rod 22. The top of the rotating rod 22 is connected to the bottom of the discharge plate 2, which is used to adjust the position or angle of the discharge plate 2. This tooling design realizes stable clamping of the workpiece, effective shielding protection and coolant supply, and improves processing efficiency and safety.

[0031] In the present invention, the detailed structure of the cutting part 4 includes a second motor 41 installed on one side of the shielding cover 3, and the output end of the second motor 41 drives the second rotating rod 42 to rotate. The end of the second rotating rod 42 is equipped with an angle-adjustable cutting disc 43 for performing a cutting operation. The second motor 41 drives the cutting disc 43 to rotate, thereby achieving precise chamfering of the workpiece.

[0032] In the present invention, the end of the rotating rod 42 is connected to the cutting disc 43 through the rotating seat 421, and the side of the cutting disc 43 is equipped with a rotating block 431. The rotating seat 421 and the rotating block 431 are rotatably connected through a rotating shaft, allowing the cutting disc 43 to adjust the angle within a certain range. This design enables the cutting disc 43 to flexibly adjust the angle according to processing requirements, thereby improving the processing flexibility.

[0033] In the present invention, a plurality of positioning holes 422 are arranged in an array around the circumference of the rotating shaft on the surface of the rotating seat 421, and a plug rod 45 is installed on one side, and the plug rod 45 can be inserted into the corresponding positioning hole 422 and the rotating block 431, so as to fix the angle of the cutting disk 43. In addition, the rotating block 431 is connected to the bearing disk 46 through a bearing, and a support frame 44 is installed on the bearing disk 46. The top of the support frame 44 is connected to the liquid spray head 322 to ensure that the coolant can be accurately sprayed to the cutting position. This structure not only realizes the fixing of the angle of the cutting disk, but also ensures the accurate supply of the coolant.

[0034] In the present invention, an electromagnet mesh plate 33 is inserted into the inner wall of the shielding plate 31 to absorb the metal powder generated during the processing. A discharge pipe 34 is installed at the bottom of the shielding plate 31 to discharge the coolant. In order to facilitate operation, a U-shaped rod 35 is installed on the top of the shielding plate 31. The U-shaped rod 35 is inserted from the top of the shielding cover 3 to facilitate the adjustment of the position of the shielding plate 31. The electromagnet mesh plate effectively collects the metal powder, the discharge pipe ensures the smooth discharge of the coolant, and the U-shaped rod provides a convenient adjustment means.

[0035] In the present invention, the workbench 1 is provided with a temporary storage box 11 at the bottom of the shielding cover 3, and a filter plate 12 is installed in the temporary storage box 11 for filtering impurities in the coolant. A discharge hopper 13 is installed on the side of the temporary storage box 11 for discharging the filtered dust. The workbench 1 is provided with a material extraction part 8 on one side of the temporary storage box 11 for processing the coolant. This design realizes the recycling of the coolant and the effective filtration of impurities, thereby improving the resource utilization rate and the cleanliness of the working environment.

[0036] In the present invention, the extraction part 8 includes an extraction pump 81 installed on the workbench 1, and the extraction pump 81 is connected to the temporary storage box 11 through a material guide pipe 82. At the same time, the extraction pump 81 is also connected to the shielding cover 3 through a hose 83 to form a circulating cooling system. The extraction pump drives the coolant to circulate between the shielding cover and the temporary storage box, ensuring a continuous cooling effect.

[0037] In the present invention, the driving part 7 includes a motor 3 71 installed on the workbench 1, and the output end of the motor 3 71 drives the threaded rod 72 to rotate. The threaded rod 72 is threadedly connected to the threaded seat 73, and the side of the threaded seat 73 is equipped with a U-shaped rod 3 74, and the U-shaped rod 3 74 is connected to the shielding cover 3. A slide groove is provided on the top of the workbench 1 for sliding of the discharge pipe 34 to ensure the smoothness of the shielding cover when moving. The motor 3 realizes the smooth movement of the shielding cover through the cooperation of the threaded rod and the threaded seat.

[0038] In the present invention, a U-shaped rod 51 is installed at the back of the push plate 5, and a rodless cylinder 52 is installed at the top of the workbench 1. The rodless cylinder 52 moves the push plate 5 by driving the U-shaped rod 51. In addition, a blowing part 9 is also provided on the top of the workbench 1 to prevent the metal powder in the shielding cover 3 from adhering when the push plate 5 moves. The rodless cylinder provides a stable thrust, and the blowing part effectively prevents the accumulation of metal powder and keeps the working area clean.

[0039] In the present invention, the blowing part 9 includes a piston cylinder 91 installed on the top of the workbench 1, and the push rod of the piston cylinder 91 is connected to the connecting rod 94, and the connecting rod 94 is connected to the U-shaped rod 2 51. The air outlet of the piston cylinder 91 is connected to the blowing pipe 93 through the hose 3 92, and the blowing pipe 93 is inserted into the shielding cover 3. The bottom of the piston cylinder 91 is equipped with an air inlet pipe 95, and the air inlet pipe 95 is equipped with a one-way valve to ensure the one-way flow of gas. When the push plate 5 moves, the piston cylinder blows air into the shielding cover through the blowing pipe, which effectively prevents the adhesion of metal powder and improves the processing efficiency and workpiece quality.

[0040] The working process of this scheme is as follows: place the workpiece to be processed on the discharge plate 2, and adjust the position of the shielding plate 31 according to the size of the workpiece to ensure that the shielding cover 3 can completely cover the workpiece. At the same time, the electromagnetic iron mesh plate 33 is in working state, ready to absorb the metal powder that may be generated, check whether the coolant in the liquid storage box 32 is sufficient, and ensure that the spray head 322 can accurately align with the cutting position of the cutting part 4, start the motor 1 21, adjust the discharge plate 2 to a suitable processing angle through the rotating rod 1 22, adjust the angle of the cutting disk 43 according to the processing requirements, and fix it in the corresponding positioning hole 422 on the rotating seat 421 through the insertion rod 45, start the motor 2 41, drive the rotating rod 2 42 and the cutting disk 43 to rotate, and start chamfering the workpiece. At the same time, start the coolant supply system in the liquid storage box 32, and spray coolant to the cutting position through the hose 1 321 and the spray head 322 to reduce the cutting temperature and prevent sparks from flying. During the cutting process, the metal powder generated is absorbed by the electromagnetic iron mesh plate 33, and the coolant passes through the discharge pipe 34 at the bottom of the shielding plate 31 After the cutting is completed, the rodless cylinder 52 is started, and the push plate 5 is pushed to move by the U-shaped rod 51 to push the workpiece out of the discharge plate 2. While the push plate 5 is moving, the piston cylinder 91 blows air into the shielding cover 3 through the hose 3 92 and the air blowing pipe 93 to prevent the metal powder from adhering to the inside of the shielding cover. The pushed workpiece can be further processed or transferred to the next process. The extraction pump 81 in the extraction part 8 is started to draw the coolant in the temporary storage box 11 back to the shielding cover through the guide pipe 82 and the hose 2 83. A circulating cooling system is formed inside the shield 3. The filter plate 12 filters out impurities in the coolant, and the filtered dust is discharged through the discharge hopper 13. The accumulation of metal powder on the electromagnet mesh plate 33 is checked regularly and cleaned in time. If necessary, the debris and residues inside the shield 3 and on the discharge plate 2 are cleaned to keep the working area clean. All motors and pump equipment are turned off, the power supply is disconnected, and the various parts of the equipment are checked to be intact. If damaged or worn, they are replaced in time, and the workpieces and materials for the next round of processing are prepared, and the above work process is repeated.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
