Description

Technical Field

[0001] This utility model relates to the field of casting spheroidization rate detection technology, and more specifically, to an automatic detection device for spheroidization rate of ductile iron castings. Background Technology

[0002] Cylindrical ductile iron, as a high-performance metallic material, is widely used in many industrial fields such as automobile manufacturing, mechanical engineering, and pipeline systems due to its high strength, good toughness, and wear resistance. The spheroidization rate, as a key indicator for measuring the quality of ductile iron castings, reflects the degree of graphite spheroidization in the casting and has a decisive impact on the mechanical properties and service life of ductile iron castings. Therefore, accurate and efficient detection of the spheroidization rate of ductile iron castings is of vital importance for ensuring product quality, improving production efficiency, and promoting the development of related industries.

[0003] A search revealed that Chinese Patent Publication No. CN217332308U discloses "An automatic detection system for the spheroidization rate of ductile iron castings, comprising a housing, one end of a hydraulic cylinder fixedly connected to the housing, a rack fixedly connected to the output end of the hydraulic cylinder, the edge of the rack meshing with two spur gears, one end of the spur gears being rotatably connected to the housing via a rotating shaft, and the other end of the spur gears being fixedly connected to a first connecting rod, one end of the first connecting rod being slidably connected to a first slider via a sliding groove. This automatic detection system for the spheroidization rate of ductile iron castings, through the cooperation between the hydraulic cylinder, spur gears, first connecting rod, first slider, second connecting rod, and fixed block, adjusts the hydraulic cylinder, causing the hydraulic cylinder to drive the rack to move downwards, the rack to cause the two spur gears to rotate in opposite directions, the spur gears to drive the first connecting rod to rotate, the first connecting rod to move the first slider outwards, and the first slider to rotate the second connecting rod, solving the problem that the automatic detection system for the spheroidization rate of ductile iron castings cannot fix castings of different sizes in the middle position." However, it still has the following drawbacks: The existing device cannot clean dust and other impurities from the surface of ductile iron castings. In actual production environments, dust, oil, or other impurities inevitably adhere to the surface of ductile iron castings during processing, transportation, and storage. These impurities severely interfere with the test values ​​of the ductile iron castings, blurring the boundary between the casting and the substrate and reducing the accuracy of the test results. Therefore, an automatic detection device for the spheroidization rate of ductile iron castings is proposed. Utility Model Content

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] like Figure 1 As shown, this embodiment proposes an automatic detection device for the spheroidization rate of ductile iron castings, including a workbench 1. The workbench 1 is equipped with a cleaning mechanism 2 for cleaning dust, oxide layer and other impurities on the surface of cylindrical ductile iron castings. The bottom of the workbench 1 is equipped with a collection component 3 for collecting the dust and other surface impurities cleaned from the cylindrical ductile iron castings. like Figure 2 - Figure 4As shown, the cleaning mechanism 2 includes an electric push rod 201 installed on the inner top wall of the workbench 1. A connecting frame 202 is installed at the output end of the electric push rod 201, and an electric motor 203 is installed at the bottom of the connecting frame 202. An L-shaped roller brush 204 is installed at the output end of the electric motor 203. The electric push rod 201 pushes the electric motor 203 and the L-shaped roller brush 204 downwards to clean dust and other impurities from the surface of the cylindrical ductile iron casting. A servo motor 205 is bolted to one side of the workbench 1. A lead screw 206 is installed at the output end of the servo motor 205. A push plate 207 is threaded onto the outer wall of the lead screw 206. A fixing rod 208 is fixedly connected to the inner wall of the workbench 1. The servo motor 205 drives the lead screw 206 to rotate, thereby moving the push plate 207. The fixing rod 208 provides stable support for the movement of the lead screw 206. An ultrasonic instrument 209 is installed at the inner top of the workbench 1. The ultrasonic transducer 209 is a BNEN 200 model from the BNEN brand, used to detect the spheroidization rate in cylindrical ductile iron castings. A high-definition camera 210, a Hikvision DS-2CD2xx6G2 model, is installed on the top inner wall of the worktable 1 to detect and view the position of the cylindrical ductile iron castings. A controller 211, a Hikvision DS-76 model, is installed on the top of the worktable 1. A support frame 212 is installed on the bottom inner wall of the worktable 1, providing stable support for the cylindrical ductile iron castings. A display screen 213 is installed on one side of the worktable 1 to display the spheroidization rate value. An auxiliary component 214 is installed inside the worktable 1, and the servo motor 205, ultrasonic transducer 209, and high-definition camera 210 are all electrically connected to the controller 211.A cylindrical ductile iron casting is placed in a mounting rack 212, which is then positioned below an electric push rod 201. The electric push rod 201 is activated, causing the connecting rack 202 to descend, which in turn lowers the electric motor 203 and the L-shaped roller brush 204 to clean dust and other impurities from the surface of the cylindrical ductile iron casting. After cleaning, the electric push rod 201 drives the electric motor 203 to rise, and the servo motor 205 drives the lead screw 206 to rotate, thereby moving the push plate 207. The fixing rod 208 provides stable support for the push plate 207. When the high-definition camera 210 detects that the mounting rack 212 and the ductile iron casting have moved to the ultrasonic instrument 209, the high-definition camera... When the optimal position is reached, a signal is transmitted to the controller 211. The controller 211 stops the movement of the servo motor 205 and reverses the servo motor 205 to move the push plate 207 to the cleaning area. Then, the ultrasonic instrument 209 is started to detect the spheroidization rate of the cylindrical ductile iron casting. The spheroidization rate of the cylindrical ductile iron casting is directly proportional to the sound velocity of the ultrasonic wave; that is, the higher the spheroidization rate, the greater the sound velocity, and vice versa. The values ​​detected by the ultrasonic instrument 209 are transmitted to the controller 211, which then transmits the detection data to the display screen 213 for easy viewing by the operator and to improve the accuracy of spheroidization rate detection in the ductile iron casting.

[0020] like Figure 3 and Figure 5 As shown, the auxiliary component 214 includes a fan 2141 mounted on the top of the workbench 1. An air delivery frame 2142 is provided at the output end of the fan 2141, and air outlet frames 2143 are fixedly connected to both sides of the air delivery frame 2142. A baffle 2144 is slidably connected to the inner wall of the workbench 1. When cleaning the cylindrical ductile iron casting, the fan 2141 blows airflow, which is then transported through the air delivery frame 2142 to the air outlet frames 2143 on both sides. The air outlet frames 2143 then evenly deliver the airflow to the position of the cylindrical ductile iron casting where dust and other impurities are being cleaned. During the cleaning of the cylindrical ductile iron casting, the baffle 2144 prevents the cleaned dust from flowing into the inspection area.

[0021] like Figure 3 As shown, the collection component 3 includes a connecting frame 301 fixedly connected to the bottom of the workbench 1. A connecting pipe 302 is provided on one side of the connecting frame 301, and an air pump 303 is provided at the end of the connecting pipe 302 away from the collection frame 304. The collection frame 304 is provided at the output end of the air pump 303. When cleaning the cylindrical ductile iron casting, the air pump 303 is started. The air pump 303 draws the cleaned dust and other impurities into the connecting frame 301, and then the connecting frame 301 transports the dust and other impurities into the collection frame 304 for collection, preventing the dust and other impurities from accumulating in the workbench 1.

[0022] like Figure 4As shown, a protective cover 4 is bolted to the top of the workbench 1, and a dustproof net 5 is installed on the inner wall of the protective cover 4. By providing stable protection for the fan 2141, the dustproof net 5 can block external dust from entering the protective cover 4, protect the fan 2141 and other components from dust contamination, and at the same time ensure the normal ventilation and heat dissipation of the fan 2141.

[0023] like Figure 4 As shown, a fixing plate 6 is fixedly connected to one side of the workbench 1, and a clamp 7 is fixedly connected to one side of the fixing plate 6. The connecting pipe 302 is fixed to the fixing plate 6 by the clamp 7 to prevent the connecting pipe 302 from shaking or shifting during operation and to ensure the stability of the connection between the connecting pipe 302 and the air pump 303.

[0024] like Figure 5 As shown, a plurality of protective pads 8 are provided on one side of the push plate 207, and the protective pads 8 are evenly distributed along the length of the push plate 207. When the push plate 207 pushes the placement rack 212, the protective pads 8 come into contact with the surface of the placement rack 212, playing a buffering and protective role, and greatly extending the service life of the push plate 207.

[0025] like Figure 4 As shown, a protective cover 9 is bolted to one side of the workbench 1, and the outer wall of the protective cover 9 has several heat dissipation holes 10. The protective cover 9 protects the servo motor 205, and the heat generated by the servo motor 205 during operation is dissipated to the outside through the heat dissipation holes 10, preventing the servo motor 205 from being damaged due to overheating and ensuring stable operation of the motor.

[0026] Specifically, in use, the automatic detection device for the spheroidal graphite casting ductile iron is as follows: The cylindrical ductile iron casting is placed in the placement rack 212, which is then placed below the electric push rod 201. Dust collected during cleaning flows into the detection area through the baffle 2144. The electric push rod 201 is activated, pushing the connecting frame 202 downwards, which in turn drives the electric motor 203 and the L-shaped roller brush 204 downwards to remove dust and other impurities from the surface of the cylindrical ductile iron casting. Simultaneously, the blower 2141 blows airflow, which is transported through the air conveyor frame 2142 to the air outlet frames 2143 on both sides. The air outlet frames 2143 then evenly distribute the airflow to the position of the cylindrical ductile iron casting being cleaned of dust and other impurities. After cleaning, the electric push rod 201 drives the electric motor 203 to rise, and the servo motor... Servo motor 205 drives screw 206 to rotate, thereby moving push plate 207. When high-definition camera 210 detects that the placement rack 212 and ductile iron casting have moved to the optimal position for ultrasonic irradiation by ultrasonic instrument 209, it transmits a signal to controller 211. Controller 211 stops the movement of servo motor 205 and reverses servo motor 205 to move push plate 207 to the cleaning area. Then, ultrasonic instrument 209 is started to detect the spheroidization rate of cylindrical ductile iron casting. The spheroidization rate of cylindrical ductile iron casting is directly proportional to the sound velocity of ultrasonic waves; that is, the higher the spheroidization rate, the greater the sound velocity, and vice versa. The values ​​detected by ultrasonic instrument 209 are transmitted to controller 211, which transmits the detection data to display screen 213 for easy viewing by operators, improving the accuracy of spheroidization rate detection in ductile iron casting (e.g., ...). Figure 2 - Figure 4 (As shown); When cleaning cylindrical ductile iron castings, the vacuum pump 303 is started. The vacuum pump 303 draws the cleaned dust and other impurities into the connecting frame 301, and then the connecting frame 301 transports the dust and other impurities to the collection frame 304 for collection, preventing the dust and other impurities from accumulating in the workbench 1 (e.g., as shown). Figure 3 (As shown).

[0027] All technical features in this embodiment can be freely combined according to actual needs.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
