Description

Technical Field

[0001] This invention belongs to the field of sensor technology, and specifically relates to a calibrable insertion ultrasonic sensor fixing device. Background Technology

[0002] An ultrasonic sensor is a sensor that converts ultrasonic signals into other energy signals (usually electrical signals). Ultrasonic waves are mechanical waves with vibration frequencies higher than 20 kHz. They are characterized by high frequency, short wavelength, minimal diffraction, and, most importantly, good directionality, enabling them to propagate directionally as rays. Ultrasonic waves have a strong penetrating power through liquids and solids, especially in solids that are opaque to sunlight. When ultrasonic waves encounter impurities or interfaces, they produce significant reflections, forming reflected echoes. When they encounter moving objects, they produce the Doppler effect. Ultrasonic sensors are widely used in industry, defense, and biomedicine.

[0003] In the later stages of production, ultrasonic sensors need to be tested for their operational status. However, when testing ultrasonic sensors on the market, the clamps used to hold all sizes of sensors can cause pressure damage to the outer surface of the ultrasonic sensor, and they do not have the capability to clean the sensor port.

[0010] Preferably, a cleaning strip is fixedly connected to the side of the upper surface of the second circular plate, and a movable annular plate is fitted on the outer surface of the cleaning strip. A square hole is opened on the lower surface of the movable annular plate, and the cleaning strip is fitted into the square hole opened on the lower surface of the movable annular plate.

[0011] Preferably, a third fixing block is fixedly connected to the inner ring of the movable annular plate, and a third circular plate is fixedly connected to the end of the third fixing block away from the movable annular plate.

[0015] Preferably, a sliding rod is slidably connected to the slot of the track box, and a spring is fixedly connected to the inner wall of the track box near the clamping box, with the end of the spring fixedly connected to the outer surface of the sliding rod.

The limit rod is rubbed and adapted to the inner wall of the arc-shaped limit plate.

[0018] The beneficial effects of this invention are:

[0019] 1. The calibrable insertion ultrasonic sensor fixing device is equipped with a rotating device that can generate a rotation effect, thereby driving the dust removal device to clean the dust at the sensing port of the ultrasonic sensor. In use, the operator connects the servo motor to the power supply and turns on the servo motor switch. The servo motor starts working, thereby driving the first rotating column and the first gear to rotate, which in turn drives the second gear, the second rotating column and the dust removal device to rotate.

[0020] II. This calibrable insertable ultrasonic sensor fixing device is equipped with a stabilizing device, which enables the ultrasonic sensor to achieve self-balancing due to its own gravity after clamping and fixing. This ensures that the ultrasonic sensor remains balanced during subsequent reprocessing. Under the influence of the ultrasonic sensor, the elastic support rods in different positions will generate different forces to compress the elastic ring, thereby achieving self-balancing during the compression of the elastic ring.

[0021] Third, the calibrable insertion ultrasonic sensor fixing device is equipped with a dust removal device, which can clean the sensing port of ultrasonic sensors of different specifications, thereby making the data more accurate when performing ultrasonic sensing. The third rotating column is not fixedly connected to the first circular plate, but is in a frictional relationship. Therefore, the first circular plate will not be driven to rotate when the dust removal device rotates.

[0022] IV. This calibrable insertion ultrasonic sensor fixing device features a movable annular plate that can adjust the cleaning level according to the depth of the sensor's sensing port, thus preventing damage to the sensor's outer surface. In use, pressing the sensor causes the outer shell to squeeze the movable annular plate. During the squeezing process, the soft arc top protects the sensor's sensing port and deforms during squeezing. Ultimately, under the influence of the first and second springs, the sensor is squeezed to the upper surface of the third circular plate. At this point, the cleaning strip will protrude through square holes, thus cleaning the dust from the sensor's sensing port while rotating.

[0023] 5. The caliable insertion ultrasonic sensor fixing device is equipped with a clamping device to clamp and fix the sensor, thereby facilitating subsequent reprocessing operations of the ultrasonic sensor and preventing the ultrasonic sensor from shifting during processing.

[0034] like Figures 1 to 8As shown, a calibrable insertion ultrasonic sensor fixing device includes a frame, which includes a base 1. A barrier cover 2 is fixedly connected to the end of the base 1, and a panel 3 is fixedly connected to the upper surface of the barrier cover 2.

[0035] The rotating device includes a servo motor 8 and a second gear 11. The servo motor 8 is fixedly connected to the shaft center of the bottom surface of the inner cavity of the base 1.

The stabilizing device 4 includes a second fixing block 44, which is fixedly connected to the upper surface of the panel 3 and located directly below the first fixing block 43. An elastic ring 45 is fixedly connected between the opposing surfaces of the first fixing block 43 and the second fixing block 44. A cleaning strip 603 is fixedly connected to the side of the upper surface of the second circular plate 602. A movable annular plate 604 is fitted onto the outer surface of the cleaning strip 603. A square hole 607 is formed on the lower surface of the movable annular plate 604. The cleaning strip 603 is fitted onto the movable annular plate 604. At the square hole 607 on the lower surface, a third fixing block 605 is fixedly connected to the inner ring of the movable annular plate 604. A third circular plate 606 is fixedly connected to the end of the third fixing block 605 away from the movable annular plate 604. There are several third fixing blocks 605, and all of the third fixing blocks 605 are fixedly connected to the inner ring of the movable annular plate 604. A hard circular ring 610 is fixedly connected to the upper surface of the soft ring 609. A second spring piece 611 is fixedly connected to the upper surface of the hard circular ring 610. A soft arc apex 612 is fixedly connected to the end of the second spring piece 611 away from the hard circular ring 610.

[0039] The clamping device 7 includes a clamping box 701, an arc-shaped limiting plate 702, and a track box 703. The clamping box 701 is fixedly connected to the side of the upper surface of the dustproof box 5. The arc-shaped limiting plate 702 is fixedly connected to the inner wall of the clamping box 701. The track box 703 is fixedly connected to the upper surface of the dustproof box 5. A sliding rod 704 is slidably connected to the slot of the track box 703. A spring 705 is fixedly connected to the inner wall of the track box 703 near the clamping box 701. The end of the spring 705 is fixedly connected to the outer surface of the sliding rod 704. A sliding rod 704 is slidably connected to the slot of the box 703. A spring 705 is fixedly connected to the inner wall of the track box 703 near the clamping box 701. The end of the spring 705 is fixedly connected to the outer surface of the sliding rod 704. An arc-shaped support rod 709 is fixedly connected to the upper surface of the fourth fixing block 706. An inclined plate 710 is fixedly connected to the top of the arc-shaped support rod 709. A limit rod 711 is fixedly connected to the outer surface of the fourth fixing block 706 away from the extrusion plate 707. The limit rod 711 is rubbed and adapted to the inner wall of the arc-shaped limit plate 702.

[0040] In use, the rotating device generates a rotation effect, which drives the dust removal device 6 to clean the dust at the sensor port of the ultrasonic sensor. During operation, the operator connects the servo motor 8 to the power supply and turns on its switch. The servo motor 8 starts working, driving the first rotating column 9 and the first gear 10 to rotate, which in turn drives the second gear 11, the second rotating column 12, and the dust removal device 6 to rotate. The stabilizing device 4 allows the ultrasonic sensor to self-balance due to its own weight after clamping and fixing, thus facilitating subsequent further processing of the ultrasonic sensor. During operation, the ultrasonic sensor is kept balanced. Under the influence of the ultrasonic sensor, the elastic support rods 41 in different positions will generate different forces to compress the elastic ring 45, thereby achieving self-balancing during the compression of the elastic ring 45. By setting a dust removal device, the sensing port of ultrasonic sensors of different specifications can be cleaned, thus making the data more accurate during ultrasonic sensing. The third rotating column 601 and the first circular plate 42 are not fixedly connected, but are in a frictional relationship. Therefore, when the dust removal device rotates, it will not drive the first circular plate 42 to rotate. By setting a movable annular plate 604, the sensor can be adjusted according to the sensor's position. The depth of the sensor port is adjusted to change the degree of dust removal, thereby preventing damage to the outer surface of the sensor. During use, pressing the sensor causes the outer casing to compress the movable annular plate 604. During this compression, the soft arc top 612 protects the sensor port and deforms during compression. Ultimately, under the influence of the first spring 608 and the second spring 611, the sensor is pressed against the upper surface of the third circular plate 606. At this point, the cleaning strip 603 protrudes through square holes 607, thus cleaning the dust from the sensor port while rotating. The clamping device 7 allows for clamping and fixing of the sensor, facilitating its operation. To prevent the ultrasonic sensor from shifting during subsequent processing, the operator aligns the sensor's sensing port with the axis of the clamping box 701 and presses it downwards. The inclined plate 710 causes the fourth fixing block 706 to move along the track of the track box 703 towards the inner wall of the clamping box 701. When the ultrasonic sensor's sensing port can no longer move downwards, it is released. At this point, the sliding rod 704 and the fourth fixing block 706, under the action of the spring 705, cause the pressing plate 707 and the soft pad 708 to press against the outer surface of the sensor, thus achieving the clamping and fixing effect.
