Description

Technical Field

[0001] This invention belongs to the field of parts processing technology, and more specifically, relates to an automated processing device for mechanical parts. Background Technology

[0002] Machining and cutting equipment is a fundamental process equipment in the machinery manufacturing field used to separate materials. Its core function is to separate parts from raw materials or process parts to a specific size and shape through the relative movement of the cutting tool and the workpiece. Among them, handheld cutting machines are particularly widely used in the processing of small and medium-sized parts, on-site construction, and emergency cutting scenarios due to their small size, light weight, and flexible operation. Its basic structure typically includes a cutting drive assembly, a handheld operating assembly, and a support assembly. The operator controls the cutting direction and force by holding the handle, achieving precise cutting of the workpiece.

[0003] The Chinese patent publication number is CN120961998A, which discloses a metal cutting machine. This invention achieves automatic coordination between the second protective cover and the cutting operation through the linkage of the first rotating rod, the second rotating rod and the pressure roller. During cutting, the second protective cover opens as the working part is pressed down, and closes automatically as the working part resets when not in operation. This effectively avoids the safety hazards caused by accidental exposure of the blade when not in operation and improves operational safety.

[0004] Existing mechanical parts processing and cutting equipment has the following disadvantages:

[0005] 1. Safety hazards caused by flying debris: When cutting mechanical parts, the high-speed friction between the cutting blade and the part of the existing handheld cutting machine causes debris to fly in all directions under the action of cutting force. These hot debris can easily adhere to the machined surface of the part, affecting the machining accuracy and surface quality of the part. They may also splash onto the operator's hands, face and other exposed parts, causing burns or cuts, posing a significant safety hazard. At the same time, the flying debris scattered on the ground and equipment surface in the work area is difficult to clean up afterward, increasing the workload of the operator.

[0006] 2. Difficulty in Self-Cleaning Collection Equipment: Although some cutting machines are equipped with simple debris collection devices, they often use fixed filters or magnetic structures, causing the collected debris to adhere tightly to the surface of the collection structure. Once a certain amount has been collected, operators need to manually disassemble the collection equipment to clean the debris. The cleaning process is cumbersome and time-consuming. If cleaning is not timely, it can also cause blockage of the collection structure, affecting the subsequent debris collection effect and failing to achieve automated self-cleaning, thus reducing the continuous operation efficiency of the equipment. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides an automated processing device for mechanical parts.

[0008] An automated machining device for mechanical parts includes a cutting disc assembly and a cutting base. The cutting disc assembly is fixedly mounted on the cutting base. The cutting disc assembly is equipped with a chip collection mechanism, and the cutting base is equipped with a chip suction mechanism. The chip collection mechanism includes a chip collection bin, a magnetic guide frame, an L-shaped support, and a collection groove. The suction mechanism includes an air pump, which is fixedly mounted on the side end of the cutting base. There are two chip collection bins, fixedly mounted on both sides of the cutting disc assembly. Two magnetic guide frames are fixedly mounted on the inner side walls of the chip collection bins. Two L-shaped supports are respectively fixedly mounted on the side ends of the two chip collection bins. Two collection grooves are respectively fixedly mounted on the rear ends of the chip collection bins. A cutting handle is provided on the side end of the cutting disc assembly. The cutting disc assembly has a rotating shaft at... An angle sensor is fixedly installed. The upper end of the cutting base has a blade clearance groove. The upper end of the air pump has a diversion pipe fixedly installed. Two suction pipes are fixedly installed on the diversion pipe. Side grooves are opened through the side ends of the two chip collection bins. Suction chambers are fixedly installed through the upper ends of the two chip collection bins. Air inlet slots are fixedly installed on the two suction chambers. Multiple air filter slots are fixedly installed on the inner side walls of the two magnetic guide frames. Arc-shaped guide slots are opened on the inner side walls of each air filter slot. Chip guide plates are fixedly installed at the lower ends of the two magnetic guide frames. The two chip guide plates are fixedly installed through the rear ends of the chip collection bins. Two collection slots are located at the lower ends of the two chip guide plates. Cylinders are fixedly installed on the side ends of the two L-shaped uprights. Permanent magnets are fixedly installed on the side ends of the two cylinders.

[0009] Preferably, the two permanent magnets are slidably mounted on the inner sidewalls of the two side slots respectively.

[0010] Preferably, the ends of both suction pipes are fixedly installed through the inner wall of the suction chamber.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In this invention, an air pump, a diversion pipe, a suction chamber, and an air inlet slot are combined to form a directional suction airflow during the cutting process. As the airflow draws the cutting debris into the chip collection chamber, it can fully contact the high-temperature debris and remove some of the heat, thus cooling the debris and reducing the safety risks associated with high-temperature debris. At the same time, the airflow collection function can effectively limit the range of debris splashing, reduce the possibility of debris injuring workers, ensure the safety of operators, and also prevent debris from contaminating the surface of the parts being processed, thereby improving the quality of the parts being processed.

[0013] In this invention, an angle sensor, a central control device, and an air pump and cylinder are used in conjunction to monitor the working status of the cutting disc assembly in real time. When the rotation angle of the cutting disc assembly exceeds a preset threshold, the central control device automatically triggers the air pump and cylinder to start. After the cutting disc assembly is reset after cutting is completed, the central control device can automatically control the air pump and cylinder to shut down. This eliminates the need for manual operation of the relevant mechanisms, simplifies the operation process, and improves the ease of use and automation of the equipment.

[0014] In this invention, a cylinder, a permanent magnet, a magnetic guide frame, and an arc-shaped guide groove are provided. When the cylinder pushes the permanent magnet to contact the magnetic guide frame, the arc-shaped guide groove of the magnetic guide frame generates a stable magnetic force. The debris drawn into the chip collection bin by the airflow is magnetically attracted to the surface of the arc-shaped guide groove. This prevents the debris from falling out of the chip collection bin or splashing again after the airflow weakens, ensuring that the debris stays stably inside the chip collection bin, improving the reliability of debris collection, and providing a guarantee for subsequent centralized processing.

[0015] In this invention, a permanent magnet, a magnetic guide frame, a chip guide plate, and a collection groove are provided. After cutting, the cylinder drives the permanent magnet to separate from the magnetic guide frame, causing the arc-shaped guide groove of the magnetic guide frame to lose its magnetic force. At the same time, the cutting disc assembly resets, causing the arc-shaped guide groove to tilt. Under the action of gravity, the chips slide down the arc-shaped guide groove to the chip guide plate and are finally collected in the collection groove. This achieves self-cleaning of the magnetic guide frame, avoids long-term chip adhesion that affects the subsequent adsorption effect, and allows the chips to be collected in a concentrated manner, making it convenient for operators to clean them uniformly and reducing maintenance costs.

[0016] In this invention, an intelligent chip handling system is constructed by using an angle sensor, a central control device, an air pump, a cylinder, and a magnetic guide frame. From cutting status recognition, airflow suction, magnetic adsorption to self-cleaning after cutting and chip collection, the entire process requires no additional manual intervention, reducing the workload of operators. At the same time, the dual effect of airflow suction and magnetic adsorption improves the chip adsorption and handling effect, keeps the cutting operation environment clean, and provides favorable conditions for the stable processing of mechanical parts.

[0026] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0027] Please see Figure 1 - Figure 8This invention provides an automated machining device for mechanical parts, including a cutting disc assembly 1 and a cutting base 2. The cutting disc assembly 1 is fixedly mounted on the cutting base 2. The cutting disc assembly 1 is provided with a collection mechanism for collecting debris, and the cutting base 2 is provided with a suction mechanism for sucking up debris. The collection mechanism includes a chip collection bin 4, a magnetic guide frame 5, an L-shaped support 6, and a collection groove 7. The suction mechanism includes an air pump 3, which is fixedly mounted on the side end of the cutting base 2. There are two chip collection bins 4, which are fixedly mounted on both sides of the cutting disc assembly 1. Two magnetic guide frames 5 are fixedly mounted on the inner side wall of the chip collection bins 4. Two L-shaped supports 6 are respectively fixedly mounted on the side ends of the two chip collection bins 4. Two collection grooves 7 are respectively fixedly mounted on the rear end of the chip collection bins 4. A cutting handle 11 is provided on the side end of the cutting disc assembly 1. The rotating shaft of the cutting disc assembly 1 is located at... An angle sensor 12 is fixedly installed, and a blade clearance groove 21 is provided at the upper end of the cutting base 2. When using this device for machining mechanical parts, the operator first holds the cutting handle 11 on the cutting disc assembly 1, places the mechanical part to be processed stably on the upper surface of the cutting base 2, adjusts the position of the part according to the cutting requirements of the part, and makes the part to be cut precisely aligned with the cutting blade of the cutting disc assembly 1. After starting the cutting function of the cutting disc assembly 1, the operator applies pressure by pressing down the cutting handle 11, which drives the cutting blade of the cutting disc assembly 1 to move towards the part. The blade clearance groove 21 provided on the cutting base 2 provides sufficient space for the cutting blade to move, avoids collision and interference between the cutting blade and the cutting base 2, and ensures that the cutting blade can smoothly contact the part and perform cutting processing to complete the predetermined cutting and shaping operation of the mechanical part.

[0028] A diversion pipe 31 is fixedly installed on the upper end of the air pump 3. Two suction pipes 32 are fixedly installed on the diversion pipe 31. Side grooves 41 are opened through the side ends of the two chip collection bins 4. Suction chambers 42 are fixedly installed through the upper ends of the two chip collection bins 4. Air inlet slots 43 are fixedly installed on the two suction chambers 42. During the cutting process, the cutting blade rubs against the material surface of the mechanical parts at high speed, which will generate a large amount of debris and dust. At the same time, the heat generated by the friction will keep the debris at a high temperature. At this time, the angle sensor 12 installed at the connection between the cutting disc assembly 1 and the cutting handle 11 will detect the rotation angle of the cutting disc assembly 1 in real time. When the detected angle exceeds the preset threshold, the angle sensor 12 will... The cutting status signal is immediately transmitted to the central control equipment. The central control equipment simultaneously starts the air pump 3 of the suction mechanism and the cylinder 61 of the collection mechanism. After the air pump 3 starts, it generates negative pressure suction. The negative pressure is evenly transmitted to the two suction pipes 32 through the diversion pipe 31. Since the end of the suction pipe 32 is connected to the suction chamber 42 on the chip collection chamber 4, the negative pressure will form a stable negative pressure environment in the suction chamber 42, thereby generating a directional suction airflow inside the chip collection chamber 4. The chips and dust generated by cutting are continuously sucked into the chip collection chamber 4 through the air inlet slot 43 on the side of the chip collection chamber 4 under the adsorption of the airflow. As the airflow moves the chips, it will fully contact the chips and take away some heat, thus achieving the initial cooling of the chips.

[0029] Multiple air filter slots 52 are fixedly installed on the inner sidewalls of the two magnetic guide frames 5. Each air filter slot 52 has an arc-shaped guide groove 51 on its inner sidewall. A chip guide plate 53 is fixedly installed at the lower end of each of the two magnetic guide frames 5. The two chip guide plates 53 are respectively fixedly installed through the rear end of the chip collection bin 4. Two collection slots 7 are respectively located at the lower end of the two chip guide plates 53. A cylinder 61 is fixedly installed at the side end of each of the two L-shaped uprights 6. A permanent magnet 62 is fixedly installed at the side end of each of the two cylinders 61. The two permanent magnets 62 are respectively slidably installed on the inner sidewalls of the two side slots 41. The ends of the two suction pipes 32 are fixedly installed through the cylinders 61. Installed on the inner wall of the suction chamber 42, the cylinder 61 starts simultaneously with the air pump 3. Its piston rod extends outward, driving the permanent magnet 62 fixed at the end of the piston rod to slide along the side groove 41 on the side of the chip collection chamber 4 into the chip collection chamber 4 until the permanent magnet 62 is in close contact with the magnetic guide frame 5 on the inner wall of the chip collection chamber 4. The magnetic guide frame 5 is magnetized under the magnetic field of the permanent magnet 62, so that the arc-shaped guide groove 51 on the inner wall of the magnetic guide frame 5 generates a stable magnetic force. When the debris sucked in by the airflow passes through the arc-shaped guide groove 51, it will be firmly attracted to the surface of the arc-shaped guide groove 51 by the magnetic force, preventing the debris from splashing again under the disturbance of the airflow.

[0030] After the mechanical parts are cut, the operator releases the cutting handle 11. The cutting disc assembly 1 rotates upward and resets under the action of its own reset mechanism. The angle sensor 12 detects that the angle of the cutting disc assembly 1 has returned to the initial state and then sends a reset signal to the central control equipment. The central control equipment immediately controls the air pump 3 to stop working and controls the piston rod of the cylinder 61 to retract, driving the permanent magnet 62 to slide back along the side groove 41 and reset, completely separating from the magnetic guide frame 5. After the magnetic guide frame 5 loses the magnetic field of the permanent magnet 62, its magnetism disappears rapidly. The arc-shaped guide groove 51 no longer has an adsorption force on the debris. During the reset process of the cutting disc assembly 1, the chip collection bin 4 and the internal magnetic guide frame 5 will tilt synchronously. The debris that was originally adsorbed on the arc-shaped guide groove 51 slides down the curved surface of the arc-shaped guide groove 51 under the action of gravity to the chip guide plate 53 at the lower end of the magnetic guide frame 5. Guided by the chip guide plate 53, it falls smoothly into the collection groove 7 below, completing the centralized collection of debris and the self-cleaning of the magnetic guide frame 5, preparing for the adsorption of debris in the next cutting process.

[0031] Working principle:

[0032] The first step, when using the device for machining mechanical parts, is for the operator to hold the cutting handle 11 on the cutting disc assembly 1 and place the mechanical part to be processed stably on the upper surface of the cutting base 2. The operator then adjusts the position of the part according to the cutting requirements, so that the part to be cut is precisely aligned with the cutting blade of the cutting disc assembly 1. After starting the cutting function of the cutting disc assembly 1, the operator applies pressure by pressing down on the cutting handle 11, which moves the cutting blade of the cutting disc assembly 1 toward the part. The blade clearance groove 21 on the cutting base 2 provides sufficient space for the cutting blade to move, avoiding collision and interference between the cutting blade and the cutting base 2, ensuring that the cutting blade can smoothly contact the part and perform cutting processing, thus completing the predetermined cutting and shaping operation of the mechanical part.

[0033] The second step involves high-speed friction between the cutting blade and the surface of the mechanical parts, generating a large amount of debris and dust. Simultaneously, the heat generated by this friction keeps the debris at a high temperature. At this time, the angle sensor 12, installed at the connection between the cutting disc assembly 1 and the cutting handle 11, continuously monitors the rotation angle of the cutting disc assembly 1. When the detected angle exceeds a preset threshold, the angle sensor 12 immediately transmits a cutting status signal to the central control device. The central control device then simultaneously activates the air pump 3 of the suction mechanism and the cylinder 61 of the collection mechanism. After the air pump 3 starts... The negative pressure suction is generated and evenly transmitted to the two suction pipes 32 through the diversion pipe 31. Since the end of the suction pipe 32 is connected to the suction chamber 42 on the chip collection chamber 4, the negative pressure will create a stable negative pressure environment in the suction chamber 42, thereby generating a directional suction airflow inside the chip collection chamber 4. The chips and dust generated by cutting are continuously sucked into the chip collection chamber 4 through the air inlet slot 43 on the side of the chip collection chamber 4 under the adsorption of the airflow. As the airflow moves the chips, it will fully contact the chips and take away some heat, thus achieving the initial cooling of the chips.

[0034] This application sets up an air pump 3, a diversion pipe 31, a suction chamber 42, and an air inlet slot 43 in conjunction to form a directional suction airflow during the cutting process. As the airflow draws the cutting debris into the chip collection chamber 4, it can fully contact the high-temperature debris and remove some of the heat, thereby cooling the debris and reducing the safety risks of high-temperature debris. At the same time, the collection effect of the airflow can effectively limit the range of debris splashing, reduce the possibility of debris splashing and injuring workers, ensure the safety of operators, and also prevent debris from contaminating the surface of the parts being processed, thus improving the quality of the parts being processed.

[0035] This application incorporates an angle sensor 12, a central control unit, an air pump 3, and a cylinder 61. The angle sensor 12 monitors the working status of the cutting disc assembly 1 in real time. When the rotation angle of the cutting disc assembly 1 exceeds a preset threshold, the central control unit automatically triggers the air pump 3 and cylinder 61 to start. After the cutting disc assembly 1 is reset after cutting, the central control unit automatically controls the air pump 3 and cylinder 61 to shut down. This eliminates the need for manual operation of the relevant mechanisms, simplifying the equipment's operation process and improving its ease of use and automation.

[0036] Thirdly, as the air pump 3 starts, the cylinder 61 also starts simultaneously. Its piston rod extends outward, driving the permanent magnet 62 fixed at the end of the piston rod to slide along the side groove 41 on the side of the chip collection bin 4 into the chip collection bin 4 until the permanent magnet 62 makes close contact with the magnetic guide frame 5 on the inner wall of the chip collection bin 4. The magnetic guide frame 5 is magnetized under the magnetic field of the permanent magnet 62, causing the arc-shaped guide groove 51 on the inner wall of the magnetic guide frame 5 to generate a stable magnetic force. When the debris sucked in by the airflow passes through the arc-shaped guide groove 51, it will be firmly attracted to the surface of the arc-shaped guide groove 51 by the magnetic force, preventing the debris from splashing again under the disturbance of the airflow. After the mechanical parts are cut, the operator releases the cutting handle 11, and the cutting disc assembly 1 rotates upward to reset under the action of its own reset mechanism. The angle sensor 12 detects that the angle of the cutting disc assembly 1 has returned to the set position. In the initial state, a reset signal is immediately sent to the central control device. The central control device immediately controls the air pump 3 to stop working and simultaneously controls the piston rod of the cylinder 61 to retract, causing the permanent magnet 62 to slide back along the side groove 41 and completely separate from the magnetic frame 5. After the magnetic frame 5 loses the magnetic field of the permanent magnet 62, its magnetism disappears rapidly, and the arc-shaped guide groove 51 no longer has an adsorption force on the debris. During the reset process of the cutting disc assembly 1, the chip collection bin 4 and the internal magnetic frame 5 will tilt synchronously. The debris that was originally adsorbed on the arc-shaped guide groove 51 will slide down the curved surface of the arc-shaped guide groove 51 under the action of gravity to the chip guide plate 53 at the lower end of the magnetic frame 5. Under the guidance of the chip guide plate 53, it will fall smoothly into the collection groove 7 below, completing the centralized collection of debris and the self-cleaning of the magnetic frame 5, preparing for the adsorption of debris in the next cutting process.

[0037] This application sets up a cylinder 61, a permanent magnet 62, a magnetic guide frame 5, and an arc-shaped guide groove 51 to cooperate. When the cylinder 61 pushes the permanent magnet 62 to contact the magnetic guide frame 5, the arc-shaped guide groove 51 of the magnetic guide frame 5 generates a stable magnetic force. The debris drawn into the chip collection bin 4 by the airflow will be magnetically attracted to the surface of the arc-shaped guide groove 51. This can prevent the debris from falling out of the chip collection bin 4 or splashing again after the airflow weakens, ensuring that the debris stays stably inside the chip collection bin 4, improving the reliability of debris collection, and providing a guarantee for subsequent centralized processing.

[0038] This application sets up a permanent magnet 62, a magnetic guide frame 5, a chip guide plate 53, and a collection groove 7 to work together. After cutting, the cylinder 61 drives the permanent magnet 62 to separate from the magnetic guide frame 5, causing the arc-shaped guide groove 51 of the magnetic guide frame 5 to lose its magnetic force. At the same time, the cutting disc assembly 1 resets and causes the arc-shaped guide groove 51 to tilt. Under the action of gravity, the chips slide down the arc-shaped guide groove 51 to the chip guide plate 53 and are finally collected in the collection groove 7. This achieves self-cleaning of the magnetic guide frame 5, avoids long-term chip adhesion that affects the subsequent adsorption effect, and allows the chips to be collected in a concentrated manner, which is convenient for operators to clean up in a unified manner and reduces maintenance costs.

[0039] This application constructs an intelligent chip handling system by setting up an angle sensor 12, a central control device, an air pump 3, a cylinder 61, and a magnetic frame 5 in conjunction with each other. From cutting status recognition, airflow suction, magnetic adsorption to self-cleaning after cutting and chip collection, the entire process requires no additional manual intervention, reducing the workload of operators. At the same time, the dual effect of airflow suction and magnetic adsorption improves the chip adsorption and handling effect, keeps the cutting operation environment clean, and provides favorable conditions for the stable processing of mechanical parts.
