The positioning assembly includes multiple fixed blocks 4, two of which are fixedly connected to the left side of the top of the workbench 1, and the other two fixed blocks 4 are fixedly connected to the right side of the top of the workbench 1, wherein a bidirectional threaded rod 5 is rotatably connected between the two fixed blocks 4, and a limiting rod 28 is fixedly connected between the other two fixed blocks 4. A motor 3 is fixedly connected to the left side of the front of the workbench 1, and the bidirectional threaded rod 5 is fixedly connected to the output end of the motor 3. One of the connecting blocks 6 is threadedly connected to the outer periphery of the bidirectional threaded rod 5, and the other connecting block 6 is slidably connected to the outer periphery of the limiting rod 28. The bottom of the workbench 1 is fixedly connected with multiple evenly distributed supporting feet 2.

[0026] Specifically, the workbench 1 is used to provide a processing platform for processing profiles. There are multiple components on the workbench 1 for easy processing. The mounting plate 7 is used to place the profiles. The electric push rod 8 is used to generate power to control the movement of the cross plate 9. The left and right ends of the cross plate 9 are rotatably connected with the rotating rod 10. When the cross plate 9 moves, the two rotating rods 10 will rotate relative to each other, so that when the rotating rod 10 rotates, a thrust will be generated to push the L-shaped block 11 to slide along the sliding rod 13. The sliding rod 13 is used to support the workbench 1 and guide the L-shaped block 11 to slide. The tops of the two L-shaped blocks 11 are fixedly connected with a clamping plate 12.

The mounting block 14 is used to support the sliding rod 13, the fixing block 4 is used to fix the bidirectional threaded rod 5 and the limit rod 28 on the workbench 1, and the supporting foot 2 is used to support the workbench 1.

[0027] Reference Figure 1 , Figure 2 , Figure 4 The cleaning component includes a motor 2 15, which is fixedly connected to the front right side of the workbench 1, and the output end of the motor 2 15 is fixedly connected to a one-way threaded rod 29, and the outer periphery of the one-way threaded rod 29 is threadedly connected to a movable arm 16, and the top of the movable arm 16 is rotatably connected to a brush plate 17, and the inside of the brush plate 17 is fixedly connected to a plurality of evenly distributed soft brushes 18, and the collection component includes a collection box 19, which is slidably connected to the rear of the workbench 1, and the left and right sides of the top of the collection box 19 are fixedly connected to handles 20, and the left and right sides of the inside of the workbench 1 The two sides are slidably connected with a lever 22, and the opposite sides of the two levers 22 are fixedly connected with an insertion rod 21, the far sides of the two levers 22 are fixedly connected with a spring 23, and the far ends of the two springs 23 are fixedly connected to the inside of the workbench 1, and the insides of the two levers 22 are slidably connected with a support rod 24, and the two springs 23 are respectively sleeved on the outer periphery of the two support rods 24, and the far ends of the two support rods 24 are fixedly connected to the inside of the workbench 1, and slots are opened on the left and right sides of the collection box 19, and the two insertion rods 21 are slidably connected in the two slots respectively.

[0028] Specifically, the motor 2 15 is used to control the one-way threaded rod 29 to rotate, and the outer peripheral thread of the one-way threaded rod 29 is connected with a movable arm 16. The movable arm 16 is a common mechanical arm in real life, which is a prior art. The movable arm 16 is used to connect a brush plate 17. The brush plate 17 can rotate inside the top of the movable arm 16 to make it more flexible. The brush plate 17 is used to connect a soft brush 18. The soft brush 18 can clean the debris generated during cutting. The collection box 19 is used to collect the debris. When the movable arm 16 drives the brush plate 17 along the one-way threaded rod. When 29 moves from the front to the back of the workbench 1, the debris at the cutting site will be swept into the collection box 19. The insertion rod 21 is used in conjunction with the slot opened in the collection box 19. When the insertion rod 21 is located in the slot, the collection box 19 is installed at the back of the workbench 1. When the insertion rod 21 slides out of the slot, the insertion rod 21 can be taken out of the workbench 1. The lever 22 is used to facilitate the operation of controlling the movement of the insertion rod 21. The spring 23 is used to provide elastic support. When the lever 22 is not moved, the spring 23 can provide support force for the lever 22. The support rod 24 is used to support the spring 23 to prevent the spring 23 from being excessively deformed and damaged when squeezed.

[0029] Reference Figure 1 - Figure 2 The cutting assembly includes a guide rod 25, which is fixedly connected to the left inner side of the workbench 1. The outer periphery of the guide rod 25 is slidably connected to a movable arm 26, and the top of the movable arm 26 is rotatably connected to a cutting tool 27.

[0030] Specifically, the movable arm 26 is the same mechanical arm as the movable arm 16, and the guide rod 25 is used to guide the movable arm 26 to slide. The top of the movable arm 26 is rotatably connected to the cutting tool 27, so that the cutting tool 27 has higher flexibility and cutting is more flexible.

[0031] Working principle: before cutting the profile, first place the two mounting plates 7 in appropriate positions according to the length of the profile to better fix the mounting plates 7, start the motor 3, and the motor 3 controls the rotation of the bidirectional threaded rod 5. When the bidirectional threaded rod 5 rotates, the connecting block 6 is affected by the thread engagement and moves along the bidirectional threaded rod 5, so that the two mounting plates 7 move toward each other. After the mounting plate 7 moves to the specified position, the profile is placed on the mounting plate 7, and then the electric push rod 8 is started to drive the cross plate 9 to contract, so that the two rotating rods 10 rotate. When the rotating rod 10 rotates, a pulling force is generated to pull the two L-shaped blocks 11 to move in both directions along the sliding rod 13, and then the two clamping plates 12 move toward each other to fix the profile, completing the positioning and facilitating processing.

[0032] Secondly, after the profile is positioned, the movable arm 26 is driven to move, so that the movable arm 26 moves along the guide rod 25, so that the cutting tool 27 reaches the accurate cutting position to cut the profile. Then, after the cutting is completed, the brush plate 17 is in a horizontal parallel state with the workbench 1, and the soft brush 18 contacts the mounting plate 7, and the motor 2 15 is started. The motor 2 15 controls the one-way threaded rod 29 to rotate. When the one-way threaded rod 29 rotates, the movable arm 16 drives the brush plate 17 to move along the one-way threaded rod 29, and the soft brush 18 is used to clean the debris at the cutting position, and the debris is cleaned into the collection box 19 for collection.

[0033] Finally, when the cleaning work is completed and the collection box 19 needs to be disassembled to dump the debris, it is only necessary to pull the lever 22, and the lever 22 drives the insertion rod 21 to move along the support rod 24 to squeeze the spring 23, and the insertion rod 21 slides out of the slot of the collection box 19. At this time, the collection box 19 can be removed, and the lever 22 is released. The spring 23 loses pressure and can be reset to generate thrust to push the lever 22 to move, so that the collection box 19 is reset.

[0034] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
