Description

Technical Field

[0001] This invention belongs to the field of casting inspection, specifically relating to a casting surface post-treatment and online inspection device. Background Technology

[0002] After demolding, castings usually have surface defects such as flash and burrs, and may also have internal defects such as porosity and shrinkage. Therefore, post-processing and quality inspection are indispensable key links in casting production.

[0003] Currently, traditional processing methods have obvious shortcomings: the deburring process mostly uses manual grinding, which is inefficient and labor-intensive. In the process of quality inspection of castings, offline sampling inspection is usually carried out, which requires the castings to be removed from the production line and transported to a special inspection station for inspection. This method is inefficient, has the risk of missed inspections, and cannot provide real-time feedback on production quality.

[0004] This application proposes a surface post-treatment and online inspection device for castings to improve the aforementioned defects. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a casting surface post-processing and online inspection device that can automatically complete the deburring process of castings and immediately perform online detection of internal defects at the same station.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A casting surface post-treatment and online inspection device includes a body, a control group, a worktable, a gap drive device, a surface treatment device, a coupling agent device, and an embedded inspection device. The worktable, capable of performing post-treatment and inspection of castings, is mounted on the body. The bottom of the worktable is connected to the control group, which is mounted on the body. A gap drive device, connected to the body, is located on the outer side of the worktable. The surface treatment device is mounted on the gap drive device. A coupling agent device is located on the other side of the worktable. An embedded inspection device is mounted on the top of the body.

[0008] In one specific implementation, the gap driving device consists of a driving component and an outer ring. The driving component is mounted on the machine body, and the outer ring is rotatably fitted on one side of the driving component. The outer ring is rotatably fitted on the machine body and has a gap fit with the worktable. The surface treatment device is mounted on the outer ring.

[0009] In one specific implementation, the surface treatment device includes a drive base, a first rotating rod, a second rotating rod, and a grinding head. The top of the drive base is connected to the first rotating rod, and the other end of the first rotating rod is connected to the second rotating rod. The grinding head is mounted on the second rotating rod. A drive motor capable of rotating the drive base, the first rotating rod, and the second rotating rod is mounted on each of them.

[0010] In one specific implementation, a torque sensor is installed inside the grinding head. The torque sensor can detect the contact force during grinding along a three-dimensional path and the torque around these three axes. The weak analog signal output by the force sensor is amplified, filtered, and converted from analog to digital by an internal signal conditioner, and then transmitted at high speed to the controller of the surface treatment device.

[0011] In one specific implementation scheme, the driving component includes a connecting frame, a motor, a main shaft, rollers, and a driving groove. The connecting frame is fixed to the machine body, and a motor is installed on one side of the connecting frame. The output end of the motor is connected to the main shaft, and a roller is installed on the main shaft. A driving groove is formed on the roller.

[0012] In one specific implementation scheme, the outer ring includes locking posts, scrapers, drainage grooves, sealing rings, and drainage grooves. The outer side of the outer ring has a plurality of locking posts arranged in a ring array, which can be movably engaged with the drive grooves on the drive component. The inner wall of the outer ring has a plurality of scrapers arranged in a ring array. The bottom of the outer ring has a plurality of drainage grooves. The outer wall of the outer ring is provided with a sealing ring, which is fixedly installed on the machine body. The sealing ring has a plurality of drainage grooves arranged in a ring array. The number of drainage grooves is the same as the number of drainage grooves. The distance between each pair of adjacent locking posts is equal to the circumference of one rotation of the drive groove on the roller.

[0013] In one specific implementation scheme, the embedded detection device includes a cylinder, an ultrasonic detection element, a servo motor, a ball screw, a movable seat, a side plate, a liquid storage tank, and a multi-dimensional nozzle. The cylinder is mounted on the top of the machine body, and the piston end of the cylinder passes through the machine body and is connected to the ultrasonic detection element. A servo motor is mounted on the machine body, and the output end of the servo motor is connected to the ball screw. A movable seat is slidably fitted on the ball screw. A side plate is fixed to one side of the movable seat, and a liquid storage tank is mounted on one side of the side plate. A multi-dimensional nozzle is mounted on the other side of the side plate, and the multi-dimensional nozzle is connected to the liquid storage tank.

[0014] In one specific implementation scheme, the multidimensional nozzle includes a connecting pipe, a first rotating pipe, a first toothed ring, a second rotating pipe, a second toothed ring, a motor base, and gears. The connecting pipe is connected to a liquid storage tank. The other end of the connecting pipe is rotatably fitted with the first rotating pipe via a bearing. A first toothed ring is installed on the outer side of the first rotating pipe. The other end of the first rotating pipe is rotatably fitted with the second rotating pipe via a bearing. A second toothed ring is installed on the outer side of the second rotating pipe near the first rotating pipe. A motor base is fixed on the outer wall of both the connecting pipe and the first rotating pipe. Gears are connected to the output end of the micro motor inside the motor base. The two gears mesh with the first toothed ring and the second toothed ring, respectively.

[0015] In one specific implementation scheme, the ultrasonic testing component includes a mounting plate, a control unit, an outer cylinder, a transmission module, a floating connector, and an ultrasonic probe. The mounting plate is connected to a cylinder, and a control unit is fixed to the bottom of the mounting plate. An outer cylinder is mounted on the bottom of the control unit. A transmission module is slidably fitted inside the outer cylinder. A floating connector is rotatably fitted on the transmission module. An ultrasonic probe is mounted on the top of the floating connector.

[0016] In one specific implementation, the transmission module has a built-in preamplifier and a wireless transmission module, which can initially amplify the acquired weak echo signal, improve the signal-to-noise ratio, and reduce signal attenuation and interference in subsequent transmission.

[0017] In one specific implementation, the control unit has a built-in wireless receiving module that transmits energy and data via electromagnetic coupling and uploads it to the host computer signal processing and imaging system via wired means such as Ethernet.

[0018] In one specific implementation, the bottom of the transmission module is connected to the bottom of the outer cylinder via a spring, which can reset the transmission module.

[0019] According to the above-mentioned technical solution, the present invention provides a casting surface post-treatment and online inspection device, which has the following beneficial effects:

[0020] (1) By integrating deburring and inspection functions into the same workstation, this invention reduces auxiliary time such as workpiece handling and positioning, greatly improves production cycle and automation, and speeds up production efficiency.

[0021] (2) The present invention uses force feedback control to detect the contact force of grinding along the three-dimensional path through the torque sensor in the grinding head. The weak analog signal output by the force sensor is amplified, filtered and converted from analog to digital by the internal signal conditioner and then transmitted to the controller of the surface treatment device at high speed. The force control algorithm running in the controller calculates according to the real-time force error, avoiding over-grinding and under-grinding in the traditional method and improving the processing consistency.

[0022] (3) The present invention realizes online detection by setting an embedded detection device on the processing table. The pulse / echo signal is transmitted through the ultrasonic probe, the signal is amplified by the preamplifier, and the analog-to-digital conversion is performed by the data acquisition card. The digitized ultrasonic data stream is sent to the wireless transmission module. The data is captured in real time and without loss by the receiving module of the control unit through electromagnetic induction coupling, crossing the physical rotation gap. The received data is transmitted to the host computer through wired means for real-time analysis, defect judgment and data storage, timely rejection of defective products or adjustment of process parameters, and improvement of product qualification rate.

[0023] (4) The present invention sprays the coupling agent evenly onto the contact area between the probe and the casting through a multi-dimensional nozzle, filling the microscopic unevenness between the probe surface and the bottom surface of the casting, eliminating air, and forming a continuous sound wave transmission path. In the centrifugal environment of high-speed rotation, a stable coupling liquid film is the premise for ensuring continuous and stable signal transmission, avoiding the coupling state from being good or bad due to rotational vibration, thus generating fluctuating detection signals. In addition, the coupling agent liquid film can play a slight lubricating and buffering role, reducing the direct friction between the probe and the surface of the casting. Especially under high-speed rotational relative motion, it helps to extend the service life of the probe.

[0024] (5) The present invention has several scrapers arrayed on the outer ring, which can scrape and concentrate the sprayed coupling agent when the outer ring rotates, and discharge it through the drainage channel, thereby improving the collection efficiency. Attached Figure Description

Detailed Implementation

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] Example 1: Please refer to Figures 1-5 The specific embodiments of the present invention are as follows:

[0039] A casting surface post-treatment and online inspection device includes a body 1, a control group 2, a worktable 3, a gap drive device 4, a surface treatment device 5, a coupling agent device 6, and an embedded inspection device 7. The worktable 3, capable of post-treatment and inspection of castings, is mounted on the body 1. The bottom of the worktable 3 is connected to the control group 2, which drives the worktable 3 to operate. The control group 2 is mounted on the body 1. The gap drive device 4, connected to the body 1, is located on the outside of the worktable 3. The surface treatment device 5, capable of surface treatment of castings, is mounted on the gap drive device 4. The coupling agent device 6 is located on the other side of the worktable 3. The embedded inspection device 7 is mounted on the top of the body 1.

[0040] Please see Figure 2 The gap drive device 4 consists of a drive component 41 and an outer ring 42. The drive component 41 is mounted on the machine body 1. The outer ring 42 is rotatably fitted on one side of the drive component 41. The outer ring 42 is rotatably fitted on the machine body 1 and has a gap fit with the worktable 3. The surface treatment device 5 is mounted on the outer ring 42.

[0041] Please see Figure 3 The surface treatment device 5 includes a drive base 51, a first rotating rod 52, a second rotating rod 53, and a grinding head 54. The top of the drive base 51 is connected to the first rotating rod 52, and the other end of the first rotating rod 52 is connected to the second rotating rod 53. The grinding head 54 is installed on the second rotating rod 53. The grinding head 54 can grind the burrs on the surface of the casting. The drive base 51, the first rotating rod 52, and the second rotating rod 53 are all equipped with drive motors that can drive them to rotate. Through the motor drive, the drive base 51, the first rotating rod 52, and the second rotating rod 53 can realize the multi-dimensional rotation of the surface treatment device 5, thereby enabling three-dimensional path grinding of the surface of the casting.

[0042] Please see Figure 3 A torque sensor is installed inside the grinding head 54. The torque sensor can detect the contact force of grinding along the three-dimensional path and the torque around the three axes. The weak analog signal output by the force sensor is amplified, filtered and converted from analog to digital by the internal signal conditioner, and then transmitted at high speed to the controller of the surface treatment device 5. The force control algorithm running in the controller calculates based on the real-time force error (ΔF = F_actual - F_desired).

[0043] When the grinding head 54 contacts the casting, the contact force increases. If it encounters a protruding burr, the actual force F_actual will instantly exceed F_desired (ΔF is positive). The algorithm will immediately calculate a backward compensation amount to make the grinding force of the surface treatment device 5 retreat and avoid over-grinding.

[0044] When polishing complex curved surfaces, even without burrs, the normal direction of the surface itself is constantly changing. Force feedback control can always ensure that the polishing force is perpendicular to the surface. When encountering depressions or holes (the force suddenly decreases, and ΔF is negative), the algorithm will control the robot to compensate forward to prevent the grinding head from "suspending" and causing under-polishing.

[0045] Please see Figure 4 The driving component 41 includes a connecting frame 411, a motor 412, a main shaft 413, a roller 414, and a driving groove 415. The connecting frame 411 is fixed on the machine body 1. The motor 412 is installed on one side of the connecting frame 411. The output end of the motor 412 is connected to the main shaft 413. The roller 414 is installed on the main shaft 413. The roller 414 has a driving groove 415. The motor 412 drives the main shaft 413 to rotate, which can synchronously drive the roller 414 located on the main shaft 413 to rotate synchronously.

[0046] Please see Figure 5 The outer ring 42 includes a locking post 421, a scraper 422, a drainage groove 423, a sealing ring 424, and a drainage groove 425. The outer side of the outer ring 42 has a ring array of locking posts 421, which can be movably engaged with the drive groove 415 on the drive member 41. The inner wall of the outer ring 42 has a ring array of scrapers 422. The bottom of the outer ring 42 is provided with a number of drainage grooves 423. The outer wall of the outer ring 42 is provided with a sealing ring 424, which is fixedly installed on the machine body 1. The sealing ring 424 is provided with a ring array of drainage grooves 425, which are the same number as the drainage grooves 423. The distance between each two adjacent locking posts 421 is equal to the circumference of the drive groove 415 on the roller 414 rotating one revolution.

[0047] Please see Figures 4-5 The motor 412 drives the roller 414 located on the main shaft 413 to rotate. The drive groove 415 on the roller 414 engages with the locking pin 421 on the outer ring 42. When the roller 414 rotates, it drives the locking pin 421 to move in the drive groove 415. The locking pin 421 drives the outer ring 42 to rotate. After a set of locking pins 421 rotates once in the drive groove 415, the next set of locking pins 421 will enter the drive groove 415 of the roller 414.

[0048] Example 2: Please refer to Figures 6-10 The specific embodiments of the present invention are as follows:

[0049] Please see Figure 6The embedded detection device 7 includes a cylinder 71, an ultrasonic detection component 72, a servo motor 73, a ball screw 74, a movable seat 75, a side plate 76, a liquid storage tank 77, and a multi-dimensional nozzle 78. The cylinder 71 is installed on the top of the machine body 1. The piston end of the cylinder 71 passes through the machine body 1 and is connected to the ultrasonic detection component 72, which can drive it to move up and down. The servo motor 73 is installed on the machine body 1. The output end of the servo motor 73 is connected to the ball screw 74. The movable seat 75 is slidably fitted on the ball screw 74. The side plate 76 is fixed on one side of the movable seat 75. The liquid storage tank 77 is installed on one side of the side plate 76. The multi-dimensional nozzle 78 is installed on the other side of the side plate 76. The multi-dimensional nozzle 78 is connected to the liquid storage tank 77. Driven by the water pump in the liquid storage tank 77, the coupling agent inside can be sprayed onto the casting.

[0050] Please see Figures 7-8 The multidimensional nozzle 78 includes a connecting pipe 91, a first rotating pipe 92, a first toothed ring 93, a second rotating pipe 94, a second toothed ring 95, a motor base 96, and gears 97. The connecting pipe 91 is connected to the liquid storage tank 77. The other end of the connecting pipe 91 is rotatably fitted with the first rotating pipe 92 through a bearing. The first toothed ring 93 is installed on the outer side of the first rotating pipe 92. The other end of the first rotating pipe 92 is rotatably fitted with the second rotating pipe 94 through a bearing. The outer side of the second rotating pipe 94 near the first rotating pipe 92 is fitted with a second toothed ring 95. Motor bases 96 are fixed on the outer walls of both the connecting pipe 91 and the first rotating pipe 92. Gears 97 are connected to the output end of the micro motor inside the motor base 96. The two gears 97 mesh with the first toothed ring 93 and the second toothed ring 95 respectively, and can drive the first toothed ring 93 and the second toothed ring 95 to rotate when rotating, thereby synchronously driving the first rotating pipe 92 and the second rotating pipe 94 to rotate.

[0051] Please see Figures 7-8 The coupling agent inside the storage tank 77 is sprayed evenly through the multi-dimensional nozzle 78 onto the contact area between the probe and the casting, filling the microscopic unevenness between the probe surface and the bottom surface of the casting, eliminating air, and forming a continuous sound wave transmission path. This ensures that a stable coupling liquid film is a prerequisite for continuous and stable signal transmission in a high-speed rotating centrifugal environment, avoiding fluctuations in the detection signal caused by the coupling state being good or bad due to rotational vibration. In addition, the coupling liquid film can play a slight lubricating and buffering role, reducing direct friction between the probe and the casting surface, especially under high-speed rotational relative motion, which helps to extend the probe's service life.

[0052] Please see Figure 9The ultrasonic testing component 72 includes a mounting plate 721, a control unit 722, an outer cylinder 723, a transmission module 724, a floating connector 725, and an ultrasonic probe 726. The mounting plate 721 is connected to the cylinder 71. The control unit 722 is fixed to the bottom of the mounting plate 721. The outer cylinder 723 is mounted on the bottom of the control unit 722. The transmission module 724 is slidably fitted inside the outer cylinder 723. The floating connector 725 is rotatably fitted on the transmission module 724. The ultrasonic probe 726 is mounted on the top of the floating connector 725.

[0053] Please see Figure 9 The transmission module 724 has a built-in preamplifier and wireless transmission module, which can initially amplify the weak echo signal collected, improve the signal-to-noise ratio, and reduce signal attenuation and interference in subsequent transmission.

[0054] Please see Figure 9 The control unit 722 has a built-in wireless receiving module that transmits energy and data via electromagnetic coupling and uploads it to the host computer signal processing and imaging system via wired means such as Ethernet.

[0055] Please see Figures 9-10 The bottom of the transmission module 724 is connected to the bottom of the outer cylinder 723 by a spring. The spring can reset the transmission module 724. When the ultrasonic probe 726 is in contact with the casting, the contact angle between the probe and the casting can be automatically adjusted through the cooperation between the floating joint 725 and the spring. When the surface of the casting is uneven, the ultrasonic probe 726 can be kept in contact with the casting in real time.

[0056] Please see Figures 9-10 The ultrasonic probe 726 is triggered to start working by the host computer in the control unit 722. The pulse / echo signal is transmitted through the probe and amplified by the preamplifier in the transmission module 724. After analog-to-digital conversion by the data acquisition card, the digitized ultrasonic data stream is sent to the wireless transmission module. The data is captured in real time and without loss by the receiving module of the control unit 722 through electromagnetic induction coupling, crossing the physical rotation gap. The received data is transmitted to the host computer via wired means for real-time analysis, defect judgment (such as porosity calculation) and data storage.

[0057] Based on the above embodiments, the specific working principle is as follows:

[0058] The finished casting is clamped and fixed on the worktable 3, and then the surface treatment device 5 is driven to operate. The grinding head 54 on it grinds the burrs on the surface of the casting. During the grinding process, the drive motor 412 drives the roller 414 on the main shaft 413 to rotate. The drive groove 415 on the roller 414 is engaged with the locking pin 421 on the outer ring 42. When rotating, the locking pin 421 can move in the drive groove 415. The locking pin 421 drives the outer ring 42 to rotate, thereby driving the surface treatment device 5 to rotate around the casting. It can perform all-round grinding of the casting. The contact force is monitored in real time by the torque sensor and the data is fed back to the controller to dynamically adjust the movement trajectory and posture of the surface treatment device 5.

[0059] After deburring is completed, the worktable 3 is driven to rotate, and the ultrasonic testing component 72 is driven to descend by the cylinder 71 until the ultrasonic probe 726 contacts the surface of the casting. At the same time, the coupling agent inside the storage tank 77 is sprayed out through the multi-dimensional nozzle 78 and evenly sprayed onto the contact area between the probe and the casting, filling the micro-uneven areas between the probe surface and the bottom surface of the casting, eliminating air, and forming a continuous sound wave transmission path. The ultrasonic probe 726 performs an all-round scan of the rotating casting, and the detection data is sent to the host computer in real time through the transmission module 724 for analysis and calculation of indicators such as porosity.

[0060] The sprayed coupling agent will flow onto the body 1 and be discharged through the trough 423 and drainage trough 425 on the outer ring 42 for collection and recycling, and then reused.
