Description

Technical Field

[0001] The invention relates to the technical field of mechanical cutting, in particular to a mechanical processing and cutting device for mechanical design and manufacturing. Background Art

[0002] In the mechanical design and manufacturing industry, mechanical processing and cutting devices, as key equipment, play a decisive role in product quality and production efficiency. However, with the rapid development of science and technology and the continuous improvement of market requirements for mechanical products, traditional mechanical processing and cutting devices have gradually exposed many limitations.

[0003] From the perspective of cutting accuracy, traditional cutting devices have difficulty maintaining a stable cutting force when facing workpieces with uneven material hardness. Due to the lack of effective pressure feedback and adjustment mechanism, the tool is easily affected by the resistance of uneven materials during the cutting process, resulting in fluctuations in cutting force and, in turn, tool chipping. This not only reduces the service life of the tool and increases production costs, but also seriously affects the cutting accuracy of the workpiece, resulting in large dimensional deviations and high surface roughness of the processed products, which cannot meet the manufacturing requirements of modern high-precision mechanical products.

[0004] There are also problems with workpiece fixation and positioning. Traditional fixation methods often use simple fixtures, which are difficult to adapt to workpieces of complex shapes and various sizes. For some special-shaped workpieces, loose fixation can easily cause displacement during the cutting process, resulting in cutting position deviation; and for some workpieces that require precise positioning, traditional fixtures cannot achieve dynamic fine-tuning, and the clamping process is cumbersome and time-consuming, seriously affecting production efficiency.

[0005] In terms of debris cleaning, traditional cutting devices lack an efficient debris separation and collection system. The debris and dust generated by cutting are often mixed together and piled up on the workbench, which not only affects the cleanliness of the working environment, but also easily causes equipment failure. Manual debris cleaning is not only labor-intensive, but also untimely cleaning will cause the debris to contaminate the workpiece again, affecting product quality.

[0006] Safety performance is also a major pain point of traditional cutting devices. Due to the lack of real-time monitoring and rapid response mechanisms, once an abnormal situation caused by human error or equipment failure occurs during the cutting process, such as accidental entry of human limbs into the cutting area or abnormal sparks during the cutting process, effective protective measures cannot be taken in time, which can easily lead to safety accidents and pose a serious threat to the life safety of operators. Summary of the invention

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Please refer to the attached Figure 1 -Attached Figure 8 The embodiment of the present invention provides a mechanical processing and cutting device for mechanical design and manufacturing, comprising a cutting table 1, a guide rail 2 is installed on the top of the cutting table 1, the guide rail 2 is symmetrically arranged, a fixed seat 3 is slidably connected to the outside of the guide rail 2, a suspension 4 is fixedly connected to the top of the fixed seat 3, a fixing mechanism is installed inside the suspension 4, which is used to fix the workpiece to be cut, a cutting assembly is installed inside the suspension 4, which is used to cut the fixed workpiece, and a cleaning assembly is installed on the top of the cutting table 1, which is used to clean the debris generated by the cutting of the workpiece; The fixing mechanism includes a fixing table 5, which is installed on the top of the cutting table 1. A fitting piece 6 is rotatably connected to one side of the outer wall of the fixing table 5. The fitting piece 6 is formed by stacking and rotatably connecting a plurality of fitting seats, which are arranged in order from large to small. The fixing table 5 and the fitting piece 6 are symmetrically arranged. A through hole 7 is provided inside the fitting piece 6, and the plurality of through holes 7 are interconnected. A straight hole 8 is provided at the bottom of the fixing table 5. A fan 9 is installed on one side of the outer side of the cutting table 1. The input end of the fan 9 is connected to the outside, and the output end of the fan 9 is connected to one end of the straight hole 8. The cleaning assembly includes a support net 13, which is arranged on the top of the cutting table 1. A layer of wedge-shaped net 14 is arranged inside the cutting table 1. A wedge-shaped hole 15 is opened inside the wedge-shaped net 14. A convection hole 16 is opened inside the fixed table 5. One end of the convection hole 16 is connected to the through hole 7. The cleaning assembly further includes a collecting plate 17, which is installed inside the cutting table 1, and the collecting plate 17 is tilted; The cross section of the convection hole 16 is Y-shaped, and a dust screen 22 is installed at one end of the convection hole 16; Specifically, the debris generated by cutting is initially filtered by the 2mm aperture of the support net 13 and then falls into the wedge-shaped net 14. The wedge-shaped hole 15 is wide at the top and narrow at the bottom (3mm at the inlet and 1mm at the outlet). The metal chips are separated from the dust by the gravity sorting principle. The larger particles slide into the collection plate 17 at an angle of 60°, and the micron-sized dust is sucked into the dust-proof net 22 through the airflow (wind speed 8-12m / s) of the Y-shaped convection hole 16. In the debris collection stage, the collection plate 17 inclined at 30° guides the debris to the collection box 19, and the electric push plate 20 in the box It is started once every 15 minutes to compress the debris into blocks with a compression ratio of 5:1, reducing the frequency of manual cleaning. The air circulation path is the negative pressure generated by the fan 9, which makes the external air flow through the support net 13, the wedge-shaped hole 15, the convection hole 16, the dust net 22, and the straight hole 8 in sequence, forming a closed-loop airflow to prevent dust from overflowing. The stacked through holes 7 form a continuous airflow channel, which forms an air path on the outer wall of the workpiece while fixing the workpiece, and completes the air path transmission to the workpiece while reducing the contact friction of the outer wall of the workpiece, reducing the friction damage to the outer wall of the workpiece.

[0024] The cutting assembly includes a hydraulic rod 10. Two groups of hydraulic rods 10 are arranged inside the suspension 4. A cutting head 11 is installed at the output end of one group of hydraulic rods 10. A pressing table 12 is fixedly connected to the output end of the other group of hydraulic rods 10. A fitting part 6 is installed inside the pressing table 12. A ball bearing 18 is provided on one side of the outer wall of the fitting member 6 provided on the press platform 12; An infrared sensor 21 is installed on one side of the inner wall of the suspension 4, and the infrared sensor 21 is electrically connected to the driving circuit of the cutting assembly; Specifically, the upper hydraulic rod 10 drives the cutting head 11 to perform vertical feed movement. The hydraulic system presets a pressure threshold (for example, 15-20MPa). When the cutting head 11 contacts the workpiece, the pressure sensor feeds back data in real time, and dynamically adjusts the oil flow through the PID algorithm to ensure constant cutting force and avoid tool chipping due to uneven material hardness. The lower hydraulic rod 10 drives the press table 12 downward, and the fitting 6 at the bottom of the press table 12 contacts the workpiece surface through the ball 18. The ball 18 is made of silicon nitride ceramic. While applying a downward pressure of 5-8kN, the workpiece is allowed to be fine-tuned in the horizontal direction to achieve dynamic clamping and self-centering functions. The infrared sensor 21 on the inner wall of the suspension 4 monitors the cutting area in real time. If human limb intrusion or abnormal sparks are detected, the hydraulic pump power supply is immediately cut off and the pneumatic brake is triggered to complete the emergency stop within 0.5 seconds.

[0025] The end of the collecting plate 17 is connected to a collecting box 19, and an electric push plate 20 is installed on one side of the inner wall of the collecting box 19, and one end of the collecting box 19 is connected to the outside; Specifically, when the weight sensor detects that the debris in the box reaches 80% of the capacity, the control system starts the electric push plate 20, which advances at a speed of 0.2m / s, and uses the serrated pressure head at the front end to break the long strips of chips. At the same time, the pressure sensor monitors the compression resistance. If it exceeds 10kN, it will automatically reverse to prevent jamming. After the compression is completed, the electromagnetic lock on the side wall of the collection box 19 opens, and the cylinder drives the box to tilt 45°. The compressed blocks are automatically discharged along the polytetrafluoroethylene coated slideway, and no human intervention is required throughout the process.

[0026] Working principle: During cutting, the infrared sensor 21 monitors the cutting area in real time to ensure safety. In the cutting assembly, the upper hydraulic rod 10 drives the cutting head 11 to perform vertical feed movement. The pressure sensor dynamically adjusts the oil flow through the PID algorithm according to the real-time feedback data to ensure constant cutting force and avoid tool chipping; the lower hydraulic rod 10 drives the press table 12 downward, and the fitting 6 at the bottom of the press table 12 contacts the surface of the workpiece through the ball 18 made of silicon nitride ceramic material, applying 5-8kN downward pressure while allowing the workpiece to be fine-tuned horizontally to achieve dynamic clamping and self-centering. In terms of the fixing mechanism, the fan 9 generates negative pressure, so that the external air forms a closed-loop airflow through the support net 13, wedge-shaped hole 15, convection hole 16, dustproof net 22, and straight hole 8 in turn. The internal through hole 7 of the stacked fitting 6 forms a continuous airflow channel, which reduces the contact friction of the outer wall of the workpiece when fixing the workpiece and completes the air path transmission, reducing friction damage. The closed-loop airflow driven by the fan 9 in the fixing mechanism and the cleaning mechanism forms an air path on the outer wall of the workpiece, which reduces the contact friction between the workpiece and the fixing mechanism, reduces the friction damage to the outer wall of the workpiece, and prolongs the service life of the workpiece. The structures such as the support net 13, the wedge net 14 and the convection hole 16 cooperate with the fan to achieve efficient separation and cleaning of metal chips and dust. The inclined collection plate 17 and the collection box 19 for automatic compression and discharge automatically start the electric push plate 20 to compress the debris every 15 minutes, which reduces the frequency of manual cleaning, reduces labor intensity, keeps the working environment clean, and improves the efficiency of debris recovery. The debris generated by cutting is initially filtered by the support net 13 and falls into the wedge net 14. The metal chips and dust are separated by the wedge hole 15 with a wide upper and narrow lower structure and the principle of gravity sorting. Larger particles slide into the collection box 19 along the collection plate 17 with a 60° inclination angle, and micron-level dust is sucked into the dustproof net 22 through the airflow (wind speed 8-12m / s) of the Y-shaped convection hole 16. In the collection box 19, when the weight sensor detects that the debris reaches 80% of the capacity, the control system starts the electric push plate 20, which advances at a speed of 0.2m / s and uses the serrated pressure head to break the long strips of chips. The pressure sensor monitors the compression resistance. If it exceeds 10kN, it automatically reverses to prevent jamming. After the compression is completed, the electromagnetic lock on the side wall of the collection box 19 opens, and the cylinder drives the box to tilt 45°. The compressed blocks are automatically discharged along the polytetrafluoroethylene coated slideway, and the electric push plate 20 is started once every 15 minutes to compress the debris into blocks, reducing the frequency of manual cleaning. The whole process ensures efficient, safe and automatic operation of cutting, fixing, cleaning and debris collection.
