The output end of the servo cylinder 404 is connected to the interlock assembly. The interlock assembly is arranged on one side of the first sliding seat 403. A second U-shaped frame 405 is fixedly connected to the bottom of the first sliding seat 403. Two second guide rods 406 are arranged inside the second U-shaped frame 405. The second sliding seat 407 is slidably installed on the outside of the two second guide rods 406. The cutting machine 5 is fixedly installed at the bottom of the second sliding seat 407. The servo cylinder 404 pushes the first sliding seat 403 to adjust the cutting position of the cutting machine 5, and the interlock assembly can interlock the servo cylinder 404 with the second sliding seat 407, thereby adjusting the cutting width of the cutting machine 5. Through the setting of the position and width adjustment mechanism 4, the operator can easily and flexibly adjust the cutting position of the cutting machine 5. This mechanism not only allows the operator to adjust the cutting width according to actual processing requirements, but also ensures that during continuous processing operations, the slotting effects of different screws can remain highly consistent. This consistency is crucial for reducing the defective product yield, which helps to improve the overall processing efficiency and quality. Finally, this adjustment mechanism can meet various actual usage requirements, ensuring that the processing process is both efficient and accurate.

[0024] According to Figure 1 、 Figure 2 and Figure 8 As shown, for the precise screw cross-slotting machine according to claim 1, it is characterized in that: an installation seat 8 is installed on one side of the workbench 1, and a dust removal and collection mechanism 9 is arranged on the top of the installation seat 8; The dust collection mechanism 9 includes a dust collection box 901, which is fixedly installed on the top of the mounting base 8.

A filter plate 904 is inserted into the dust collection box 901, and a collection box 905 is inserted into the dust collection box 901. A dust hood 906 is installed on the other side of the dust collection box 901. Through the setting of the dust collection mechanism 9, the collection of metal chips and dust generated during metal cutting can be effectively realized. This measure not only helps prevent these chips and dust from polluting the working environment, but also ensures that the air in the working area remains clean, thus providing a healthier and safer working environment for the staff.

[0025] According to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the position and width adjustment mechanism 4 includes a first U-shaped frame 401. A servo cylinder 404 is fixedly installed at one end of the servo cylinder 404. Two first guide rods 402 are arranged inside the first U-shaped frame 401.

Through the setting of the position and width adjustment mechanism 4, the operator can not only obtain great flexibility in adjusting the cutting position and width, but also optimize the mechanical structure and transmission system of the equipment. This optimization significantly reduces the vibration and error during the processing, thereby improving the processing stability. With the improvement of the stability, the grooving accuracy is further improved, ensuring the reliability of the processing quality.

[0026] According to Figure 4 As shown, the interlock assembly includes an interlock block 10, which is fixedly installed at the output end of the servo cylinder 404. A displacement sensor 11 is installed on one side of the interlock block 10. Electronic interlockers 12 are symmetrically installed on one side of the first sliding seat 403 and the second sliding seat 407. Two electronic lock shaft devices 13 are installed on one side of the first sliding seat 403, and the two electronic lock shaft devices 13 correspond to the two first guide rods 402 respectively. Through the setting of the interlock assembly, the operator can flexibly adjust the operating state of the position and width adjustment mechanism 4 according to actual needs. This automatic adjustment mechanism significantly reduces the necessity of manual intervention, thereby improving the operation safety. At the same time, it also reduces the difficulty of using the equipment, making the operation more intuitive and easy to understand. Finally, this intelligent adjustment method can effectively improve the overall work efficiency, ensuring a smoother and more efficient production process.

[0027] According to Figure 1 、 Figure 2 and Figure 3As shown, the main body mechanism 2 includes four struts 201, and the four struts 201 are respectively fixedly installed on the top of the workbench 1. The top of the four struts 201 is fixedly installed with a top plate 202. Through the setting of the main body mechanism 2, it can effectively provide a solid support foundation for the entire device, thereby significantly reducing the occurrence of vibration and error during the processing. This optimized structural design helps to improve the stability of the processing process and ensure the consistency and accuracy of the processing quality.

[0028] According to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the cutting depth adjustment mechanism 3 includes two guide columns 301. The two guide columns 301 are arranged between the workbench 1 and the top plate 202. A sliding frame 302 is slidably installed on the outer sides of the two guide columns 301. A fixed frame 303 is fixedly installed on the top of the sliding frame 302. A servo electric cylinder 304 is installed on the top of the top plate 202. The output end of the servo electric cylinder 304 movably penetrates through the top plate 202 and is connected to the fixed frame 303. Through the setting of the cutting depth adjustment mechanism 3, the operator can flexibly set and adjust the cutting depth, so as to meet the grooving requirements of various different specifications and requirements. This adjustment mechanism can not only further improve the efficiency of the grooving operation, but also significantly improve the quality and accuracy of the grooving operation.

[0029] According to Figure 1 、 Figure 2 and Figure 6 As shown, a rotating mechanism 6 is arranged at the bottom of the workbench 1; The rotating mechanism 6 includes a fixed frame 601. The fixed frame 601 is fixedly installed at the bottom of the workbench 1. A first servo motor 602 is installed inside the fixed frame 601. The output end of the first servo motor 602 movably penetrates through the workbench 1 and is connected to a clamping mechanism 7. Through the setting of the rotating mechanism 6, it can effectively drive the screw to be grooved to perform precise rotation operations. Such a design not only meets the processing requirements for cross-shaped grooving, but also significantly improves the accuracy and efficiency during the cross-grooving processing.

[0030] According to Figure 1 、 Figure 2 、 Figure 6 and Figure 7As shown in the figure, the clamping mechanism 7 includes a pallet rack 701. One end of the pallet rack 701 is equipped with a second servo motor 702. The output end of the second servo motor 702 movably penetrates through the pallet rack 701 and is connected to a lead screw 703. There are two sliding blocks 704 arranged on the outer side of the lead screw 703. The top of each sliding block 704 is connected to a clamping block 705. Two clamping brackets 706 are installed at the opposite ends of the two clamping blocks 705. Through the setting of the clamping mechanism 7, the clamping and fixing of various screws to be processed can be effectively realized, ensuring its stability during the processing. This clamping mechanism can not only adapt to bolts of different sizes but also has high flexibility, thus being able to meet various diverse requirements. Through this design, the versatility of the equipment can be significantly improved, enabling it to serve different processing scenarios more efficiently.

[0031] According to Figure 1 、 Figure 2 and Figure 6 As shown in the figure, a limit ring 15 is provided at the top of the workbench 1. Both ends of the bottom of the pallet rack 701 are provided with brackets 14. Both brackets 14 are attached to the outer side of the limit ring 15. Through the setting of the brackets 14 and the limit ring 15, the stability and compressive resistance of the clamping mechanism 7 can be significantly improved. Such an improvement helps to reduce the adverse effects on the equipment during the cutting process, thereby ensuring the continuous consistency and reliability of the grooving accuracy.

[0032] According to Figure 1 、 Figure 2 and Figure 6 As shown in the figure, feet 16 are installed at the four corners of the bottom of the workbench 1. A non-slip pad 17 is fixedly installed at the bottom of each foot 16. Through the setting of the feet 16 and the non-slip pads 17, a stable support foundation can be effectively provided for the entire equipment. This design not only ensures the stability of the equipment during use but also further reduces the unnecessary shaking and displacement phenomena that may occur during the operation of the equipment through the increased friction between the non-slip pads 17 and the ground.

[0033] Working principle: First, place the entire equipment at the designated position to ensure that the non-slip pads 17 are in close contact with the ground, which can significantly increase the friction, thus cooperating with the feet 16 to provide a stable support foundation for the equipment. Then, correctly connect the external power supply to the electrical equipment inside the processing machine to ensure that the equipment can obtain stable power supply and operate normally. Next, connect the displacement sensor 11, the electronic interlock 12, the electronic lock shaft device 13, and multiple servo devices to the external control system to form a closed information interaction network. Through this collaborative operation method, an efficient control scheme can be realized to ensure the accuracy and reliability of the equipment operation.

[0034] In the preparation stage, first, the end of the screw to be processed needs to be facing upward, and then it is placed at the top position of the pallet rack 701. Next, the second servo motor 702 is started, and the second servo motor 702 drives the lead screw 703 to rotate. As the lead screw 703 rotates, the two sliding blocks 704 will move accordingly. They drive the corresponding clamping blocks 705 to slide and gradually approach the screw. During this process, multiple clamping frames 706 will work together to precisely clamp and fix the screw to ensure its stability during processing.

[0035] In the position adjustment stage, first, the external control system controls the electronic interlock 12 installed on the first sliding seat 403 to combine with the interlock block 10 to form a precise interlock mechanism. Once the interlock mechanism is activated, the external control system will control the servo cylinder 404 to start. The telescopic action of the servo cylinder 404 will drive the first sliding seat 403 to perform a smooth sliding motion along the first guide rod 402. At the same time, the displacement sensor 11 will monitor and record the displacement data in real time to ensure the accuracy of the entire process. Through these data, the external control system can accurately control the position of the cutting machine 5 so that it moves to the predetermined position for slot cutting directly above the screw, thereby performing precise cutting operations.

[0036] In the grooving processing stage, first, start the cutting depth adjustment mechanism 3. This mechanism will, through a series of precise mechanical actions, push the fixed frame 303 by the cutting depth adjustment mechanism 3, and then drive the sliding frame 302 to slide on the two guiding columns 301. The purpose of this process is to make the cutting machine 5 closer to the screw to be grooved for precise grooving processing. Subsequently, start the cutting machine 5 to start grooving the screw. During this process, in order to ensure the accuracy and stability of the processing, the external control system will play a role and control the two electronic lock shafts 13 to lock the corresponding first guiding rods 402, which can effectively prevent any unnecessary displacement of the first sliding seat 403. Immediately afterwards, the external control system will continue to perform its control function, control the electronic interlock 12 installed on the first sliding seat 403 to release the interlock with the interlock block 10, and then the control system will control the electronic interlock 12 installed on the second sliding seat 407 to interlock with the interlock block 10, so that the second sliding seat 407 can slide following the expansion and contraction of the servo cylinder 404. After that, start the servo cylinder 404 again. Through the precise control of the servo cylinder 404, push the second sliding seat 407 to drive the cutting machine 5 to slide precisely on the two second guiding rods 406 to precisely adjust the width of the groove. When the one-way straight groove cutting is completed, in order to carry out the next processing, start the first servo motor 602. The first servo motor 602 will drive the clamping mechanism 7, and the clamping mechanism 7 will drive the clamped and fixed screw to rotate by 90°, so as to carry out the cross-grooving processing.

[0037] In the dust and chip collection stage, during the grooving processing, first, start the two blowers 903. These two blowers 903 will jointly generate a strong suction force. The function of this suction force is to effectively suck away the metal chips and dust generated during the grooving processing. These metal chips and dust will be guided to the dust collection hood 906 and then centrally sucked into the dust removal box 901. Inside the dust removal box 901, the filter plate 904 filters the inhaled air to separate the metal chips and dust. The filter plate 904 will block these particulate matters so that they cannot pass through with the air but will fall into the collection box 905 below. After the grooving processing task is completed, the operator can easily pull the pull ring at the end of the collection box 905 to take out the collection box 905 from the dust removal box 901 to centrally process the collected metal chips and dust. At the same time, in order to keep the filter plate 904 clean and efficient, the operator can also pull the pull ring at the top of the filter plate 904 to pull out the filter plate 904 from the dust removal box 901 for necessary cleaning or replacement work to ensure that the filtering effect is always in the best state.

[0038] By operating according to the above content, the use of the precise cross-grooving processing machine for screws can be completed.
