Description

Technical Field

[0001] This utility model relates to the field of forging inspection technology for lifting shafts, and in particular to an online defect detection and rejection device for forging large lifting shafts. Background Technology

[0002] Large lifting shafts are key load-bearing components in heavy machinery, lifting and transportation equipment, and metallurgical machinery. They need to withstand high-intensity tensile, bending, and impact loads for a long time. Their forging quality directly determines the operational safety and service life of the equipment. These components are usually formed by multiple hot forging processes using high-quality alloy structural steel. They are characterized by their large size, high forging precision requirements, and equal importance of internal quality and surface performance. They are widely used in the lifting mechanisms of cranes, the opening and closing equipment of water conservancy projects, and the core parts of the spindle system of heavy machine tools. They are an important part of ensuring the stable operation of heavy equipment.

[0003] Currently, the technological development of online defect detection and rejection devices for large-scale hanging shafts shows a trend of gradual automation: some production lines have introduced basic online detection equipment, setting up fixed ultrasonic probes at the end of the forging production line to scan the internal defects of the shaft body, using fixed industrial cameras to collect images of regular parts such as the journal, and using simple algorithms to identify obvious scratches. In the rejection process, pneumatic push rods are used to push manually marked defective products to the scrap area. Some equipment has achieved preliminary storage and display of detection data, providing a foundation for subsequent quality traceability.

[0004] However, the existing model has obvious shortcomings in adaptability to modern production: offline strength testing is not only time-consuming and labor-intensive, but the clamping accuracy of the testing fixtures is unstable, making it difficult to accurately reflect the actual load-bearing capacity of the shaft; manual visual inspection is affected by factors such as experience and fatigue, resulting in poor consistency in the identification of minor defects and a high risk of missed inspections; manual measurement of dimensional tolerances is inefficient and cannot cover all key dimensions, leading to an increased risk of defective products leaving the factory; secondly, the existing inspection links are independent of each other and lack a coherent automated flow mechanism, requiring a large amount of manual intervention in the inspection and rejection process, which seriously restricts the improvement of production efficiency and quality stability.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an online defect detection and rejection device for large-scale hanging shaft forging, including a sloping conveyor frame 1 for guiding the workpiece to be inspected to move in a specified direction.

A power system 5 is provided at the lower part of the detection and rejection mechanism 3 to provide power to the transmission system. A workpiece output device 6 is provided in front of the stress detection mechanism 2 to output the inspected workpiece in a directional manner.

[0031] The stress testing mechanism 2 includes multiple inclined rollers 201, which ensure the smooth descent of the workpiece while finely adjusting its orientation. The multiple inclined rollers 201 are rotatably connected to the upper middle part of the inclined conveyor frame 1. A slide rail groove 202, slightly larger than the workpiece being tested, is provided on the top right side of the inclined conveyor frame 1. A fixing block 203 is fixedly connected to the middle right side of the inclined conveyor frame 1, located directly below the slide rail groove 202, for receiving and transferring the workpiece. A push rod compartment 204 is fixedly connected to the middle left side of the inclined conveyor frame 1. An electric push rod 205 is installed inside the push rod compartment 204, which can push the workpiece to the next target position. Two rotating wheels 206 are rotatably connected inside the fixing block 203, causing the workpiece to rotate and thus adjusting its angle. A fixed connection is provided at the bottom right side of the inclined conveyor frame 1. A cylindrical base 207 is attached to fix the detection device and provide power to the detection device. A rotating ring 208 is rotatably connected to the top of the cylindrical base 207, and the detection work can be carried out cyclically by rotating. A tool column 209 is fixedly connected to the center of the top of the cylindrical base 207, which carries the detection tool. An electric pressure block 210 is set at the bottom rear side of the tool column 209, which moves downward to apply pressure to the workpiece. A push rod compartment 211 is fixedly connected to the lower middle part of the front side of the tool column 209. An electric push rod 212 is set at the center of the front side of the push rod compartment 211 to push out the workpiece after detection. The top of the rotating ring 208 has multiple fixing slots 213, and each fixing slot 213 is fixedly connected to a hanging shaft assembly 214 for combining with the workpiece to be tested and detecting the shape of the workpiece.

[0032] The suspension shaft assembly 214 includes a shaft core body 2141, which is the basic support component of the entire suspension shaft. A bushing 2142 is attached to the bottom of the shaft core body 2141. The shaft core body 2141 and the bushing 2142 are fixedly connected to the fixing groove 213. A connecting sleeve 2143 is attached to the inner wall of the shaft core body 2141 and the bushing 2142. The inner wall has splines that mesh with the part to be tested 4. Screw holes 2 are opened in the middle of the left and right sides of the shaft core body 2141 and the bushing 2142. 144, multiple screw holes 2144 are threaded with bolts 2145, screw holes 2144 and bolts 2145 are combined to fix the shaft body 2141 and the bushing 2142 and tighten the connecting sleeve 2143. Screw holes 2146 are opened on the top left and right sides of the shaft body 2141, and multiple screw holes 2146 are threaded with bolts 2147. Screw holes 2146 and bolts 2147 are used to connect the lifting shaft to the external mechanism.

[0033] Specifically, the inclined conveyor frame 1 serves as a workpiece conveying and guiding structure. The stress detection mechanism 2 on its right side is rotatably connected to the upper part of the inclined conveyor frame 1 via multiple inclined rollers 201, ensuring the workpiece falls and allowing for fine-tuning of its direction. When the workpiece moves along the inclined conveyor frame 1 and reaches the top right slide rail groove 202, the workpiece can slide directly below and be supported by the fixed block 203 because the slide rail groove 202 is sized to fit the workpiece being tested. At this time, the two rotating wheels 206 rotatably connected within the fixed block 203 are activated, causing the workpiece to rotate and adjust its angle. Simultaneously, the electric push rod 205 in the push rod compartment 204 on the left side of the inclined conveyor frame 1 actuates, pushing the workpiece to the corresponding testing position. The cylindrical base 207 is fixed to the bottom right side of the inclined conveyor frame 1, providing support and power for the testing device. Its top rotating ring 208 rotates, enabling the testing cycle to continue. The tool column 209 carries the testing tool, and the rear bottom electric pressure block 210 moves down to apply pressure to the workpiece to test its strength. The electric push rod 212 in the lower front push rod compartment 211 pushes the workpiece out after inspection. The hanging shaft assembly 214 in the top fixing groove 213 of the rotating ring 208 is fixed with the shaft core body 2141 and the bushing 2142. The connecting sleeve 2143 fits against the inner wall of the shaft core body 2141 and the bushing 2142. The spline pattern on the inner wall engages with the workpiece 4 to be inspected. The shaft core body 2141 and the bushing 2142 are fixed by the screw hole 2144 and the bolt 2145, and the connecting sleeve 2143 is tightened. The screw hole 2146 and the bolt 2147 are used for subsequent connection of the hanging shaft to the external mechanism. This realizes the inspection of the workpiece shape, etc., and cooperates with the visual, weight inspection and rejection functions of the left inspection rejection mechanism 3. The power system 5 provides power for transmission. The workpiece output device 6 outputs the inspected workpiece in a directional manner, completing the online inspection and processing process of large hanging shaft forgings, ensuring efficient and accurate inspection, and rejecting unqualified products.

[0034] Reference Figure 1 , Figure 2 and Figure 6The detection and rejection mechanism 3 includes a weight detector 301, which weighs the workpieces arriving at the location and uploads the weight data. A conveyor belt 302 is placed to the right of the weight detector 301 to transport workpieces passing through it. A conveyor belt 303 is placed to the left of the weight detector 301 to transport undetected workpieces. A work cabinet 304 is fixedly connected to the rear of the weight detector 301 to compare the workpiece detection data with set values ​​and provide feedback. An extension arm 305 is fixedly connected to the middle left side of the work cabinet 304 to mount detection and gripping tools. A camera rod 306 is fixedly connected to the top left side of the extension arm 305. The front end of the camera rod 306... The work cabinet 304 is equipped with a lens 307 to capture images of workpieces passing in front of the lens 307. A rotating arm 308 is fixedly connected to the top right side of the extension arm 305, which can rotate to the left. A mechanical claw 309 is provided at the bottom front end of the rotating arm 308 for gripping defective workpieces. An extension arm 310 is fixedly connected to the middle right side of the work cabinet 304 to install gripping tools. A rotating arm 311 is fixedly connected to the top center of the extension arm 310, which can rotate to the right. A mechanical claw 312 is provided at the bottom front end of the rotating arm 311 for gripping defective workpieces. An interactive component 313 is electrically connected to the outer wall of the work cabinet 304 to control the equipment, display equipment information, and display test data.

[0035] The interactive component 313 includes a detection display 3131 that displays detection data. The detection display 3131 is electrically connected to the top front side of the work cabinet 304. A detection control button 3132 is electrically connected to the upper middle part of the front side of the work cabinet 304 to control the detection and rejection work. A device manager 3133 is electrically connected to the top of the work cabinet 304 to display the device status and control the device switch.

[0036] Specifically, in the inspection and rejection mechanism 3, the weight detector 301 weighs the arriving workpieces and uploads the weight data. The right conveyor belt 302 transfers the weighed workpieces, and the left conveyor belt 303 transfers the uninspected workpieces. The rear work cabinet 304 receives the data and compares it with the set value for feedback. The left extension arm 305 of the work cabinet 304 installs tools, and the front lens 307 of the top left camera rod 306 captures the workpiece. The top right rotating arm 308 can rotate to the left, and the front mechanical claw 309 grabs the defective products. The right extension arm 310 installs tools, and the top rotating arm 311 can rotate to the right. The front mechanical claw 312 grabs the defective products. The interaction component 313 on the outer wall of the work cabinet 304 displays the data through the inspection display instrument 3131. The inspection control button 3132 controls the inspection and rejection. The equipment manager 3133 displays the equipment status and control switches. Together, they realize the inspection and rejection process of the workpieces, ensuring accurate inspection and effective rejection, and completing the inspection and processing of large hanging shaft forgings.

[0037] Reference Figure 1 , Figure 3 and Figure 5 The upper part of the inclined conveyor frame 1 and the detection and rejection mechanism 3 both convey the workpiece to be tested 4. The workpiece to be tested 4 flows in the device as the workpiece to be tested. The hanging shaft assembly 214 is meshed with the workpiece to be tested 4. The power system 5 is connected to the first conveyor belt 302 and the second conveyor belt 303 through the transmission belt to provide power for the flow of the workpiece to be tested 4.

[0038] Specifically, in the upper part of the inclined conveyor frame 1 and the inspection and rejection mechanism 3, the workpiece 4 to be inspected is transferred as the workpiece to be tested. The hanging shaft assembly 214 is connected to the workpiece 4 to be inspected through the spline pattern on its inner wall to achieve the adaptation inspection of the shape of the workpiece 4 to be inspected. The power system 5 is connected to the first conveyor belt 302 and the second conveyor belt 303 through the transmission belt, driving the conveyor belt to operate and providing power for the transfer of the workpiece 4 to be inspected in the device. This ensures that the workpiece 4 to be inspected passes through stress testing, weight and visual inspection in sequence, completing the online inspection and rejection process for defects in large hanging shaft forging. This enables the various devices to operate in coordination and promotes the orderly development of the inspection work.

[0039] Reference Figure 1 and Figure 2 The workpiece output device 6 includes an output platform 601, which is placed at an angle to guide the workpiece 4 to be inspected after inspection to the discharge port. The rear side of the output platform 601 is tangent to the rotating ring 208. A baffle 602 is fixedly connected to the top left end of the output platform 601 to prevent the workpiece 4 to be inspected from falling due to inertia. The feeding device 7 conveys the workpiece 4 to be inspected after production but before inspection to the second conveyor belt 303.

[0040] Specifically, in the workpiece output device 6, the output platform 601 is placed at an angle, with its rear side tangent to the rotating ring 208. When the workpiece 4, which has been tested by the stress testing mechanism 2, rotates to the tangent position with the rotating ring 208, it slides onto the output platform 601. Because the output platform 601 is tilted, the workpiece 4 is guided to move along the platform surface to the discharge port. The baffle 602 at the top left end of the output platform 601 prevents the workpiece 4 from deviating from the path and falling due to inertia, ensuring the stable discharge of the workpiece 4. This completes the directional output process of the workpiece 4 after testing for large hanging shaft forging, connecting the testing and subsequent collection links, and ensuring that the workpiece flows out of the device in an orderly manner. The feeding device 7 receives the workpiece 4 that has not been tested after production and transfers it to the adjacent conveyor belt 303 via a ramp, which facilitates the subsequent testing of the workpiece 4.

[0041] Working principle: During stress testing, the workpiece 4 to be tested is conveyed by the inclined conveyor frame 1 and its direction is adjusted by multiple inclined rollers 201. It then enters the slide rail groove 202 and slides into the fixed block 203. The rotating wheel 206 in the fixed block 203 drives the workpiece 4 to rotate to adjust the angle. Subsequently, the electric push rod 205 in the push rod compartment 204 pushes the workpiece 4 to the fixed groove 213 at the top of the rotating ring 208. The spline pattern on the inner wall of the connecting sleeve 2143 is adapted to the workpiece 4 to engage with the hanging shaft assembly 214. If the workpiece 4 to be tested cannot be inserted into the hanging shaft assembly 214, it indicates that the stress test is not working. If the test piece 4 is unqualified, it will continue to be pushed by the electric push rod 205, but it will fall and be rejected because it cannot proceed to the next step. The cylindrical base 207 provides support and rotation power for the rotating ring 208. The rotating ring 208 rotates and drives the test piece 4 to the inspection station. The electric pressure block 210 on the rear side of the tool column 209 moves down to apply pressure to the test piece 4 and test its strength. After the inspection is completed, the electric push rod 212 in the push rod compartment 211 pushes the test piece 4 to the output platform 601 of the workpiece output device 6. The test piece 4 slides along the output platform 601. The baffle 602 at the top left end prevents it from falling due to inertia.

[0042] During the visual inspection, weight inspection, and rejection process, the uninspected workpiece 4 is presented by the feeding device 7 and enters the top of the second conveyor belt 303. When the top of the second conveyor belt 303 reaches the visual inspection position, the lens 307 captures an image of the workpiece 4. The captured image is transmitted to the work cabinet 304 for inspection. If the surface of the workpiece 4 shows obvious defects, it will be judged as a defective product, and the work cabinet 304 will send a rejection command to the rotating arm 308 and the robotic gripper 309. The robotic gripper 309 extends downward and grabs the defective workpiece 4. After grabbing, the rotating arm 308 rotates to the left. After reaching the predetermined position, the rotating arm 308 stops rotating, and the robotic gripper 309 releases the defective workpiece 4. After rejection, the rotating arm 308 and the robotic gripper 309 return to their original positions. The workpiece 4, which has completed visual inspection, is conveyed by conveyor belt 303 to weight detector 301. Weight detector 301 weighs it and uploads the data to work cabinet 304. If the weight of the workpiece 4 is outside the tolerance range, it is judged as a defective product. Work cabinet 304 sends a rejection command to rotating arm 311 and robotic gripper 312 to reject the next workpiece 4 entering the rejection range. The robotic gripper 312 picks up the workpiece, and then rotating arm 311 rotates to the right to reject the defective workpiece 4. The workpiece 4, which has undergone visual inspection and weight inspection, is conveyed by conveyor belt 302 to the next stage. Through the cooperation of various components, the inspection and rejection are automated and continuous, which effectively improves the problems of low automation and discontinuous inspection and rejection systems in the existing technology.
