Technical Field

[0001] The utility model relates to the technical field of clamping devices, and particularly relates to a clamping device for a phased array ultrasonic wheel shaft processing adaptive device. Background Technique

[0002] The basic idea of ultrasonic phased array technology comes from radar electromagnetic wave phased array technology. A phased array radar is composed of many radiation units arranged in an array. By controlling the amplitude and phase of each unit in the array antenna, the radiation direction of electromagnetic waves is adjusted, and a flexible and fast focusing scanning radar beam is synthesized within a certain space range.

[0003] When it is necessary to detect the wheel shaft, a phased array ultrasonic detection device needs to be used, and the phased array ultrasonic probe is attached to the wheel shaft for detection.

[0004] However, during the detection of the wheel shaft by the existing probe, it is necessary to ensure the perpendicularity between the center of the probe and the center of the axle. When encountering the situation of workpiece axial surface protrusion or axle radial swing during the detection process, the existing probe clamping device cannot adjust the position of the probe to adapt to the wheel shaft, thus affecting the detection accuracy.

[0025] Support plate 2;

[0026] A movable block 9 located inside the support plate 2, and the movable block 9 is used to enable the ultrasonic detection device to fit the wheel axle;

[0027] The top of the support plate 2 is provided with a mounting block 1, the mounting block 1 is connected to the support plate 2 through a fastener, both sides of the fixing block 3 are connected to the inside of the support plate 2 through a fixed shaft, a sliding groove 12 is opened inside the fixing block 3, a slider 14 is arranged inside the sliding groove 12 and is slidably connected to one end of the slider 14, the end of the slider 14 away from the sliding groove 12 is connected to the movable block 9 by welding, a second elastic member 7 is arranged on the top of the movable block 9, a fixing plate 8 is arranged on the top of the second elastic member 7, a first elastic member 6 is arranged on the fixing plate 8, a column 13 is arranged on the top of the movable block 9. When detecting the wheel axle, the probe 10 is supported on the surface of the wheel axle through the pulley 5, and the clamping device of the probe 10 automatically fits and aligns with the wheel axle surface according to gravity. The first elastic member 6 pushes the fixing plate 8 through the limiting post 11, and the fixing plate 8 pushes the fixing block 3 through the column 13 to adapt to the amplitude of the wheel axle surface, and then the wheel axle is rotated for detection. When encountering uneven positions of the wheel axle, the first elastic member 6 and the second elastic member 7 can achieve up and down floating, driving the probe 10 to float up and down together. When the wheel axle swings radially and the fitting point of the roller of the probe 10 clamping device is automatically positioned, the adjustment is completed, and the effect of making the probe 10 adapt to the wheel axle surface can be achieved, reflecting the practicability of this device.

[0028] Specifically, the outside of the fixing block 3 is connected to the top of the connecting block 4 through a fastener, a pulley 5 is arranged at the bottom of the connecting block 4, and both sides of the pulley 5 are connected to the connecting block 4 through a rotating shaft.

[0029] Through the above technical solution, the connecting block 4 is used to support the pulley 5. A plurality of connecting blocks 4 and pulleys 5 are arranged on the fixed block 3 for supporting the fixed block 3.

[0030] Specifically, the bottom of the column 13 is located above the movable block 9. The extended end of the bottom of the column 13 is embedded inside the movable block 9. The other end of the column 13 is connected to the fixed plate 8 in an embedded form. The second elastic member 7 is located outside the column 13.

[0031] Through the above technical solution, the fixed plate 8 can slide up and down on the column 13, and the second elastic member 7 completely wraps the column 13.

[0032] Specifically, the inner side of the movable block 9 is connected to the probe 10 by a fastener, and the movable blocks 9 are symmetrically distributed on the fixed block 3.

[0033] Through the above technical solution, the movable block 9 can move up and down in the inner chute 12 of the fixed block 3 through the slider 14, thereby driving the probe 10 to adjust the height. Through the guidance of the chute 12 and the slider 14, the probe 10 is prevented from tilting and shifting during movement.

[0034] Specifically, a limit post 11 is provided at the top of the fixed plate 8. The extended end of the limit post 11 is located inside the fixed plate 8. The bottom of the first elastic member 6 is located outside the limit post 11.

[0035] Through the above technical solution, the first elastic member 6 is only limited by the limit post 11 at the bottom, which facilitates the first elastic member 6 to drive the fixed block 3 to achieve angle adjustment. At the same time, the top of the first elastic member 6 is located inside the top of the inner wall of the support plate 2 to prevent the first elastic member 6 from tilting to the outside when bending.

[0036] Specifically, the second elastic members 7 are mirror-symmetrically distributed on the movable block 9, and the first elastic members 6 are equally spaced on the fixed plate 8.

[0037] Through the above technical solution, the second elastic member 7 is used to drive the probe 10 to adjust the up and down amplitude, so that the probe 10 can adapt to the uneven surface of the wheel axle.

[0038] Specifically, the top of the first elastic member 6 is located at the bottom of the inner wall of the support plate 2. The other end of the first elastic member 6 supports on the fixed plate 8. The top of the second elastic member 7 supports on the bottom of the fixed plate 8. The other end of the second elastic member 7 supports on the top of the movable block 9.

[0039] Through the above technical solution, the fixed plate 8 can float up and down through the first elastic member 6 and the second elastic member 7, thereby driving the fixed block 3 to adjust the angle so that it can adapt to wheel axle surfaces at different angles.

[0040] During use, when detecting the axle first, the probe 10 is supported on the surface of the axle through the pulley 5. The clamping device of the probe 10 automatically fits and aligns with the surface of the axle according to gravity. The first elastic member 6 pushes the fixing plate 8 through the limit post 11, and the fixing plate 8 pushes the fixing block 3 through the column 13 to adapt to the amplitude of the axle surface, ensuring the perpendicularity between the center of the probe 10 and the center of the axle. Then, the axle is rotated for detection. When encountering uneven positions on the axle, the second elastic member 7 can float up and down. The probe 10 pushes the second elastic member 7 upward through the movable block 9. The column 13 passes through the fixing plate 8, and through the resilience of the elastic member, it drives the probe 10 to float up and down together, achieving that when the axle swings radially, the rolling contact point at the bottom of the fixing block 3 of the probe 10 will automatically be positioned to complete the adjustment, and then the work can be completed.
