DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] See also Figures 1 to 7 A multi-axis linkage processing mechanism of a CNC machine tool includes a machine body 1, a controller 2 is arranged on the machine body 1, a rotating placement table 11 is arranged inside the machine body 1, a clamping device 12 is installed on the rotating placement table 11, a feeding device 13 is arranged inside the machine body 1, a mounting table 14 is slidably installed on the feeding device 13, and a tool assembly 16 is installed on the mounting table 14.

[0019] The rotating placement table 11 is used to carry the workpiece to be processed, and can realize multi-angle rotation to adapt to different processing requirements. The clamping device 12 is used to fix the workpiece to ensure that the position of the workpiece remains stable during the processing. The feeding device 13 is responsible for the precise movement of the tool assembly 16 in the X, Y, Z and other directions. The mounting table 14 provides an installation platform for the tool assembly 16 and other related components. The tool assembly 16 is a core component for performing actual cutting operations. Since this part is a prior art, it will not be repeated here.

[0020] A protection mechanism, a slag discharging mechanism, a slag blowing mechanism, a driving mechanism and a pressing mechanism are arranged on the mounting platform 14 , and a slag collecting mechanism is arranged inside the machine body 1 .

[0021] The protection mechanism can protect the tool, avoid damage caused by accidental breakage of the tool and avoid debris splashing as much as possible. The slag removal mechanism can remove the waste chips collected by the protection mechanism during the processing. The slag blowing mechanism cleans the tool and the processing area through airflow. The driving mechanism can control the action of the protection mechanism. The compression mechanism is used to activate the slag blowing machine. The slag collecting mechanism can collect and process processing waste.

[0022] The protection mechanism includes a fixed half frame 17, the number of the fixed half frames 17 is two, the two fixed half frames 17 are both slidably mounted on the mounting table 14, the two fixed half frames 17 are both fixedly mounted with a movable half frame 18, the two fixed half frames 17 are both fixedly mounted with a first fixed block 19, the two movable half frames 18 are both fixedly mounted with a second fixed block 21, the first fixed block 19 is provided with a telescopic rod 20, and the other end of the telescopic rod 20 is fixedly mounted on the second fixed block 21.

[0023] The cross-sections of the fixed half frame 17 and the movable half frame 18 are both n-shaped, and the tool assembly 16 is located in the rectangular space formed by the fixed half frame 17 and the movable half frame 18 .

[0024] When the telescopic rod 20 is started, the distance between the movable half frame 18 and the fixed half frame 17 can be adjusted, so that the extended length of the tool assembly 16 can be controlled, so that the tool assembly 16 can smoothly perform deep processing activities, and when performing plane processing activities, under the action of the telescopic rod 20, the two movable half frames 18 can smoothly fit with the surface of the processing object, thereby avoiding debris splashing as much as possible.

[0025] The movable half frame 18 is retracted into the fixed half frame 17 by controlling the telescopic rod 20, and the debris on the movable half frame 18 can fall down smoothly.

[0026] The slag unloading mechanism includes two connecting plates 22 , and both connecting plates 22 are fixedly mounted on the mounting platform 14 . Push brushes 32 are embedded and mounted on the upper and lower ends of the connecting plates 22 , and the push brushes 32 can directly contact the corresponding fixed half frame 17 .

[0027] When the two fixed half frames 17 are moved to both sides respectively, the push brush 32 on the connecting plate 22 can move relative to the corresponding fixed half frame 17, thereby directly acting on the fixed half frame 17 to effectively remove the waste residue attached to the fixed half frame 17.

[0028] The driving mechanism includes a stepper motor 29, which is mounted on a mounting platform 14. A bidirectional lead screw 31 is fixedly mounted on the shaft output end of the stepper motor 29. Two nut pairs 27 are threadedly mounted on the bidirectional lead screw 31. The two nut pairs 27 are fixedly connected to the corresponding fixed half frames 17 respectively.

[0029] The start of the stepper motor 29 can cause the bidirectional lead screw 31 to rotate, thereby causing the two nut pairs 27 to move closer to or farther away from each other, thereby achieving control of the protection mechanism.

[0030] The slag blowing mechanism includes a fixed frame 23 which is fixedly installed on the mounting table 14, and the number of the fixed frames 23 is two. An airbag 24 is arranged inside the fixed frame 23. Branch nozzles 25 are fixedly installed on both of the two airbags 24, and a main pipeline 26 is fixedly installed on the two branch nozzles 25. The main pipeline 26 corresponds to the end of the tool assembly 16 away from the mounting table 14.

[0031] The airbag 24 stores compressed air. Preferably, a one-way valve can be arranged inside the airbag 24 to allow external air to enter the airbag 24 to supplement gas, and at the same time prevent the air from flowing back from the air inlet during the compression process, ensuring that an effective air flow can be generated each time it is squeezed. A particulate filter can be built inside the airbag 24 to prevent dust particles in the external environment from entering the airbag 24 together with the fresh air, avoiding secondary pollution. Since it is prior art, it will not be elaborated here.

[0032] The branch nozzles 25 guide the gas to the designated position, and the main pipeline 26 can centrally manage the air flow direction to ensure that the blown gas can effectively clean the tool and the processing area, which is convenient for use.

[0033] The pressing mechanism includes connecting rods 28. The number of the connecting rods 28 is two. The connecting rods 28 are slidably installed on the mounting table 14, and the connecting rods 28 are fixedly connected to the corresponding nut pairs 27. A pressing plate 30 is fixedly installed on the connecting rods 28, and the pressing plate 30 can directly contact the corresponding airbag 24.

[0034] When the driving mechanism is started, the two fixed half frames 17 can be gradually separated, so that the tool assembly 16 can be smoothly exposed. At the same time, the pressing plate 30 can directly contact the corresponding airbag 24 to generate the air flow required for slag blowing by compressing the airbag 24.

[0035] A protective door 3 is slidably installed on the machine body 1. A slider 8 is fixedly installed on the side of the protective door 3 facing the machine body 1, and a chute 7 for the slider 8 to slide is provided at the corresponding position on the machine body 1.

[0036] Through the cooperation of the slider 8 and the chute 7, the smooth opening and closing of the door can be ensured.

[0037] The slag collection mechanism includes a slag receiving plate 15, a slag loading tank 6 and a mounting frame 9. The slag receiving plate 15 is fixedly installed inside the machine body 1 and is located below the rotating placement table 11. The slag loading tank 6 is slidably installed on the machine body 1. One side of the slag receiving plate 15 away from the rotating placement table 11 abuts against the slag loading tank 6. The mounting frame 9 is fixedly installed on the protective door 3, and a cleaning brush 10 is fixedly installed on the mounting frame 9. The cleaning brush 10 can directly contact the slag receiving plate 15.

[0038] During the processing, the debris generated can directly fall onto the slag receiving plate 15. When the processing is completed, by opening the protective door 3, the cleaning brush 10 on the protective door 3 and the mounting bracket 9 will move synchronously. The cleaning brush 10 can drive the debris on the slag receiving plate 15 to move until it is pushed into the slag loading groove 6. When the slag loading groove 6 is full, the slag loading groove 6 can be directly pulled out for cleaning, which can effectively improve the cleaning efficiency.

[0039] A handle 4 is fixedly installed on the protective door 3, and an observation window 5 is inlaid on the protective door 3. The handle 4 facilitates the operator to open or close the protective door 3, and the observation window 5 allows real-time monitoring of the processing situation.

[0040] The working process of the present invention: Open the protective door 3 through the handle 4 on the protective door 3, and use the cooperation of the slider 8 and the chute 7 to ensure its stable movement. Place the workpiece to be processed in the clamping device 12 on the rotating placement table 11 and fix it. Close the protective door 3 to ensure operation safety and can monitor the processing process in real time through the observation window 5.

[0041] The feeding device 13 drives the mounting table 14 and the tool assembly 16 thereon to the designated position for clamping and processing activities. The activation of the telescopic rod 20 can adjust the length of the tool assembly 16 extending out of the protection device, ensuring that the tool can smoothly fit the surface of the workpiece during deep processing or surface processing to reduce debris splashing. The tool assembly 16 performs cutting processing on the workpiece. During this process, the protection mechanism provides physical protection for the tool to avoid tool damage caused by external factors.

[0042] When preliminary cleaning activities are required, the stepping motor 29 is started, and the bidirectional lead screw 31 rotates, causing the two fixed half-frames 17 and the corresponding moving half-frames 18 to move relative to each other as needed. The pushing brush 32 directly acts on the fixed half-frame 17 to effectively remove the waste residue attached thereto. The waste residue falls onto the slag receiving plate 15 by gravity. At the same time, the connecting rod 28 in the collection and pressing mechanism moves with the nut pair 27 to compress the airbag 24, generating an air flow that is discharged through the branch nozzle 25 and the main pipeline 26 to remove the debris from the tool assembly 16 and the processing area, keeping it clean and improving the processing accuracy.

[0043] Open the protective door 3 again to take out the processed workpiece. When the protective door 3 is opened, the cleaning brush 10 on the mounting bracket 9 will move synchronously, driving the debris on the slag receiving plate 15 into the slag loading groove 6 for subsequent cleaning.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
