Description

Technical Field

[0001] The present invention relates to the field of ultrasonic phased arrays, and more particularly to an ultrasonic phased array detection device for forgings. Background Art

[0002] A forging refers to a workpiece obtained by forging and deforming a metal blank.

[0003] When forgings are manufactured, quality inspection is required. In related technologies, the inspection of forgings is usually carried out by ultrasonic phased arrays. The basic idea of ultrasonic phased array technology comes from electromagnetic wave phased array technology. It is composed of many units arranged in an array. By controlling the amplitude and phase of each unit, the radiation direction is adjusted, and a flexible and fast scanning radar beam is synthesized within a certain space range.

[0004] The inventor believes that when performing ultrasonic phased array detection on forgings, placing the forgings on the workbench for detection results in partial blind spots in the detected forgings. Ultrasonic phased array detection cannot perform omnidirectional detection on forgings, and detection errors are likely to occur. Summary of the Invention

[0005] In order to improve the defect that when placing the forging on the workbench for detection, there are partial blind spots in the detected forging, ultrasonic phased array detection cannot perform omnidirectional detection on the forging, and detection errors are likely to occur, the present application provides an ultrasonic phased array detection device for forgings.

[0006] The ultrasonic phased array detection device for forgings provided by the present application adopts the following technical solutions:

[0007] An ultrasonic phased array detection device for forgings includes a workbench, on which a feeding mechanism, a placing mechanism, and a detection mechanism are arranged. The feeding mechanism includes a conveying track and a sliding plate slidably connected to the conveying track. A feeding cylinder is arranged on the sliding plate. The placing mechanism is placed on one side of the sliding plate. The feeding cylinder is used to push the forging onto the placing mechanism. The placing mechanism includes a support frame arranged on the workbench and a plurality of flipping plates arranged on the support frame. At least two flipping plates are arranged along the length direction of the support frame. The side of the flipping plate away from the sliding plate is rotatably connected to the support frame. A flipping assembly for rotating the flipping plate is arranged on the workbench. The detection mechanism includes a detection frame arranged on the workbench and a detection probe arranged on the detection frame. The detection frame is arranged on one side of the support frame. The detection probe is used to perform ultrasonic phased array detection on the forging on the flipping plate.

[0008] By adopting the above technical solution, the forging is placed on the feeding mechanism. The forging is sent to one side of the placing mechanism through the sliding plate, and then pushed by the feeding cylinder to the turning plate closest to the sliding plate. When the forging is placed on the turning plate, the detection mechanism performs ultrasonic detection on the forging. After the first detection, the forging is moved to the second turning plate by the turning of the turning plate. When the forging is turned to the second turning plate, the forging is flipped. Then the detection probe performs a secondary detection on the forging, and so on, so as to perform a full - range detection on the forging, further reducing the possibility of forging detection errors and improving the comprehensiveness of forging detection.

[0009] Optionally, a plurality of connecting rods are rotatably arranged on the support frame. One side of the turning plate is fixed on the connecting rod, and a plurality of abutting rods are arranged on the support frame. One end of the turning plate abuts against the abutting rod.

[0010] By adopting the above technical solution, the connecting rods arranged on the support frame are rotatably connected to the turning plate through the connecting rods, which facilitates the rotation of the turning plate. The abutting rods can improve the stability of the turning plate when it is placed horizontally, making the detection of the forging more stable.

[0011] Optionally, the range of the angle formed between the turning plate and the workbench surface after rotation is 0° - 90°.

[0012] By adopting the above technical solution, setting the angle between the turning plate and the workbench surface to 0° - 90° can facilitate the forging to roll from one turning plate to the other.

[0013] Optionally, the turning assembly includes a plurality of pushing cylinders arranged on the workbench. The cylinder body of the pushing cylinder is hinged to the workbench, and one end of the piston rod of the pushing cylinder is hinged to the turning plate.

[0014] By adopting the above technical solution, one end of the pushing cylinder is hinged to the turning plate and the other end is hinged to the workbench, which can facilitate the control of the turning angle of the turning plate and further make the turning more stable.

[0015] Optionally, a rotating groove is formed on the turning plate, and a rotating plate is rotatably connected in the rotating groove. A driving motor for driving the rotating plate to rotate is arranged on the turning plate.

[0016] By adopting the above technical solution, the rotating plate is rotatably connected in the rotating groove. When the detection probe detects, the driving motor drives the rotating plate to rotate, so as to rotate the forging, further improving the comprehensiveness of forging detection and reducing the possibility of detection blind areas.

[0017] Optionally, an anti - slip layer is arranged on the rotating plate, and the range of the friction coefficient μ of the anti - slip layer is μ > 1.

[0018] By adopting the above technical scheme, setting the friction coefficient between μ>1 can ensure that when the flip plate is lifted, the forging will not slide down at the first time. When the flip plate is flipped to more than 45°, it will slide down. When the flip plate is flipped to more than 45 degrees, it will slide down. When the forging is more than 45°, it can be convenient for the forging to flip after sliding down, so that the placement angle on the flip plate at the rear is different from that at the front.

[0019] Optionally, the detection frame is provided with a moving component for driving the detection probe to move along the length direction of the support frame, the moving component includes a sliding block slidably connected to the detection frame, and a driving cylinder arranged on the detection frame, the piston rod of the driving cylinder is fixedly connected to the sliding block, and the detection probe is fixedly connected to the sliding block.

[0020] By adopting the above technical solution, the cylinder is pushed to drive the sliding block to move, thereby moving the detection probe. The detection probe can follow the forging after the flip plate drives it to flip, thereby further improving the stability of the detection.

[0021] Optionally, a threaded block is slidably connected in the sliding track, the threaded block and the sliding plate are fixedly connected, a threaded rod is passed through the threaded block, the threaded rod is rotatably connected in the sliding track, and a driving member for driving the threaded rod to rotate is provided at one end of the sliding track.

[0022] By adopting the above technical solution, the threaded rod is driven to rotate by the driving member, so that the threaded block slidably connected in the sliding track is rotated and moved, driving the sliding plate to move, thereby facilitating the loading of the workpiece and further improving the degree of automation of detection.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The forging is placed on the feeding mechanism, and the sliding plate is used to feed the forging to one side of the placement mechanism. The feeding cylinder pushes the forging to the flip plate closest to the sliding plate. When the forging is placed on the flip plate, the detection mechanism performs ultrasonic detection on the forging. After the first detection, the forging is flipped to the second flip plate by flipping the flip plate. When the forging moves to the second flip plate, the forging is flipped, and then the detection probe performs a second detection on the forging, and so on, so as to perform all-round detection on the forging, further reduce the possibility of errors in forging detection, and improve the comprehensiveness of forging detection.

[0025] 2. Set the angle between the flip plate and the workbench surface to 0°-90°, which can facilitate the forging to flip and roll from one side of the flip plate to the other side.

[0026] 3. Setting the friction coefficient between μ > 1 can prevent the forging from slipping immediately when the turning plate is lifted. When the turning plate is turned to an angle greater than 45°, the forging slips. When the turning plate is greater than 45 degrees and the forging slips, and when the forging is greater than 45°, the forging slips, which can facilitate the forging to flip after slipping, so that the placement angle on the rear turning plate is different from that on the front.

The cylinder block of the pushing cylinder 15 is hinged to the tabletop of the workbench 1, and the piston rod of the pushing cylinder 15 is hinged to the side of the turning plate 8 close to the workbench 1.
