Description

Technical Field

[0001] The invention relates to measurement and calibration technology, and in particular to a device and method for measuring and calibrating the outer dimensions of a transportation tool. Background Art

[0002] At present, motor vehicle inspection stations use vehicle outline detectors to detect the vehicle's external dimensions. The specific detection process is that when a vehicle passes through the detection area of ​​the vehicle outline detector at a certain speed, the vehicle outline detector will obtain the length, width and height data of the vehicle. In order to ensure the detection accuracy of the vehicle outline detector, it is necessary to regularly calibrate the length, width and height of the vehicle outline detector. The current calibration method is to calibrate the motor vehicle external dimension measuring instrument through measuring instruments such as steel tape measures and auxiliary measuring rods. These measuring instruments themselves have certain errors. At the same time, there are also certain errors in manual operation, which makes the error of manual calibration larger.

[0003] Therefore, it is necessary to use other more accurate instruments for calibration, such as using a measuring rod and a laser rangefinder to calibrate the vehicle's external dimensions (length, width, height and other parameters). The laser rangefinder measures the distance between the ends of the measuring rod (length, width) and the distance between the ends of the measuring rod and the ground (height) as the reference values ​​of the length, width and height of the vehicle's external dimensions, and compares them with the measurement results of the length, width and height of the external dimensions detected by the vehicle external dimension detector, and calculates the indication error to achieve metrological calibration of the vehicle external dimension measuring instrument. However, in actual measurement, the external body of the vehicle is usually not completely regular, and the front and rear of the vehicle may not be on the same vertical plane, resulting in the calibration devices at different ends not being in the same straight line, and the measuring rod is bulky and inconvenient to adjust, making it difficult to complete the calibration work quickly and accurately. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned problems and provide a device for measuring and calibrating the outer dimensions of a transportation vehicle.

[0005] Another object of the present invention is to provide a method for measuring and calibrating the outer dimensions of a transportation vehicle.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0008] The magnetic chuck is used to be magnetically attached to the outer side of the vehicle;

[0009] The measuring assembly comprises a measuring mounting rod and a laser rangefinder or a laser reflective target arranged on the measuring mounting rod;

[0010] The calibration adjustment mechanism is arranged between the magnetic chuck and the measuring assembly, and comprises an X-direction adjustment mechanism for linearly adjusting the position of the measuring assembly in the X direction, a Y-direction adjustment mechanism for linearly adjusting the position of the measuring assembly in the Y direction, a Z-direction adjustment mechanism for linearly adjusting the position of the measuring assembly in the Z direction, and a rotation adjustment mechanism for rotationally adjusting the position of the measuring assembly, the adjustment direction of the X-direction adjustment mechanism is perpendicular to the adjustment direction of the Y-direction adjustment mechanism, the planes on which the adjustment directions of the X-direction adjustment mechanism and the Y-direction adjustment mechanism are located are parallel to the corresponding outer side surface of the vehicle, the adjustment direction of the Z-direction adjustment mechanism is perpendicular to the corresponding outer side surface of the vehicle, and the adjustment rotation center of the rotation adjustment mechanism is perpendicular to the corresponding outer side surface of the vehicle.

[0011] In a preferred embodiment of the present invention, a magnetic switch is provided on the magnetic chuck, and the surface of the magnetic chuck is wrapped with a rubber sleeve, so that the paint surface of the vehicle to be tested can be effectively protected to avoid damage to the vehicle body.

[0012] A preferred embodiment of the present invention is that the measuring mounting rod comprises a first measuring mounting rod and a second measuring mounting rod, the first measuring mounting rod is fixedly connected to the calibration adjustment mechanism, the second measuring mounting rod is telescopically arranged in the inner cavity of the first measuring mounting rod, and the laser rangefinder or laser reflection target is provided on the end of the second measuring mounting rod away from the first measuring mounting rod.

[0013] Furthermore, a level is provided on the first measuring mounting rod, which can provide a horizontal reference for the first measuring mounting rod when measuring the length and width of the vehicle, and provide a vertical reference for the first measuring mounting rod when measuring the height of the vehicle.

[0014] In a preferred embodiment of the present invention, the X-axis adjustment mechanism comprises a first mounting seat, an X-axis movable seat and an X-axis adjustment structure, wherein the first mounting seat is fixedly connected to the magnetic chuck through a tripod; the X-axis adjustment structure comprises an X-axis adjustment screw and an X-axis adjustment screw hole, wherein the X-axis adjustment screw hole is provided on the X-axis movable seat, the X-axis adjustment screw passes through the X-axis adjustment screw hole, and the two ends of the X-axis adjustment screw are rotatably connected to the two ends of the first mounting seat. Through the above structure, applying a force on the X-axis movable seat can push the X-axis movable seat to move along the axial direction of the X-axis adjustment screw, thereby completing the X-axis adjustment.

[0015] Further, the Y-direction adjustment mechanism includes a Y-direction moving seat and a Y-direction adjustment structure, the Y-direction adjustment structure includes a Y-direction adjustment screw and a Y-direction adjustment screw hole, the Y-direction moving seat is arranged in the groove of the first mounting seat, the Y-direction adjustment screw hole is provided on the Y-direction moving seat, the axis of the Y-direction adjustment screw is skewed and perpendicular to the axis of the X-direction adjustment screw, the Y-direction adjustment screw passes through the Y-direction adjustment screw hole, and the two ends of the Y-direction adjustment screw are rotatably connected to the two ends of the Y-direction moving seat. Through the above structure, applying a force on the Y-direction moving seat can push the Y-direction moving seat to move along the axial direction of the Y-direction adjustment screw, thereby completing the Y-direction adjustment.

[0016] Furthermore, the Y-axis adjustment mechanism further includes an anti-slip positioning structure, which is provided with two groups and symmetrically arranged on both sides of the Y-axis movable seat, and each group of anti-slip positioning structures includes an anti-slip fixed seat, a follow-up unlocking ball, a follow-up plate, an elastic self-locking member and a manual unlocking rod;

[0017] The anti-slip fixed seat is fixedly set on the X-direction moving seat, and a mounting portion is provided on the anti-slip fixed seat, and two limit plates are provided on the mounting portion, and arc-shaped surfaces are provided on the two limit plates; the follow-up unlocking ball is arranged on the mounting portion and is located between the two limit plates; the follow-up plate is fixedly connected to the side of the Y-direction moving seat; the elastic self-locking piece covers the arc-shaped surfaces of the two limit plates, and the lower end of the elastic self-locking piece is fixed on the arc-shaped surface, and the upper end of the elastic self-locking piece is against the side of the follow-up plate; in the projection parallel to the Z direction, the follow-up unlocking ball is seamlessly surrounded by the mounting portion of the anti-slip fixed seat, the elastic self-locking piece and the side of the follow-up plate; one end of the manual unlocking rod is fixedly connected to the elastic self-locking piece, and one end of the manual unlocking rod extends to the outside through the anti-slip fixed seat.

[0018] Through the above structure, before use, the elastic self-locking piece is pulled by the manual unlocking rod to make the upper end of the elastic self-locking piece away from the side of the follower plate, and the Y-axis moving seat is moved to the starting position (the end of the Y-axis adjusting screw, that is, the lowest position when in use) for subsequent Y-axis adjustment. Since the calibration and measurement mechanism is placed horizontally when measuring the length and width of the vehicle, and the Y-axis moving seat and the Y-axis adjusting screw are both in an upright state, it is difficult to achieve stable self-locking only by the friction between the Y-axis adjusting screw and the Y-axis moving seat, and it is easy to slide down. Therefore, it is necessary to realize the follow-up self-locking through the anti-slip positioning structure, and at the same time, it will not affect the movement of the Y-axis moving seat. The specific operation is: when pushing the Y-axis moving seat, the follower plate moves upward synchronously, and acts on the follow-up unlocking ball, so that the follow-up unlocking ball rotates and presses the elastic self-locking piece upward, so that the upper end of the elastic self-locking piece is away from the side of the follower plate, and the locking of the follower plate is released, and the upward movement of the Y-axis moving seat is not interfered. When the Y-axis moving seat stops, the follow-up unlocking ball loses its upward driving force, the follow-up unlocking ball resets, and the upper end of the elastic self-locking member resets and presses against the side of the follow-up plate, locking the follow-up plate and the Y-axis moving seat to prevent the Y-axis moving seat from sliding down due to excessive gravity.

[0019] Furthermore, the rotation adjustment mechanism includes a rotation adjustment bearing, the axis of which is perpendicular to the axis of the Y-axis adjustment screw and the axis of the X-axis adjustment screw, the outer ring of which is fixed on the Y-axis movable seat, and the inner ring of which is fixedly connected to the Z-axis adjustment mechanism.

[0020] Furthermore, the Z-direction adjustment mechanism includes a second mounting seat, a mounting frame and a Z-direction adjustment structure, wherein the second mounting seat is fixedly connected to the inner ring of the rotary adjustment bearing; the mounting frame is fixedly connected to the measuring mounting rod; the Z-direction adjustment structure is provided with multiple groups and each group includes a Z-direction telescopic adjustment seat, a Z-direction telescopic adjustment rod and a locking pin, wherein the Z-direction telescopic adjustment seat is fixedly arranged on the second mounting seat, a Z-direction telescopic adjustment hole is provided on the Z-direction telescopic adjustment seat, one end of the Z-direction telescopic adjustment rod is fixedly connected to the mounting frame, and the other end of the Z-direction telescopic adjustment rod extends into the Z-direction telescopic adjustment hole, and the locking pin is used to pass through the Z-direction telescopic adjustment seat to lock the Z-direction telescopic adjustment rod. Through the above structure, if Z-direction adjustment is to be performed, the locking pin is first loosened, and then the mounting frame and the measuring mounting rod are pushed in the corresponding direction, thereby completing the Z-direction adjustment.

[0021] A method for measuring and calibrating the outer dimensions of a transportation tool comprises the following steps:

[0022] When measuring the length and width of a vehicle, a calibration measuring mechanism with a laser rangefinder and a calibration measuring mechanism with a laser reflective target are respectively selected, the two calibration measuring mechanisms are horizontally placed and fixedly installed at both ends of the same outer side of the vehicle, and then the laser rangefinder is started to measure the distance; if the laser rangefinders and laser reflective targets of the two calibration measuring mechanisms are not on the same straight line, they need to be adjusted through the calibration adjustment mechanism;

[0023] If the laser rangefinders and laser reflective targets of the two calibration and measuring mechanisms are not on the same horizontal plane, adjust the Y-axis adjustment mechanism of one or both calibration and measuring mechanisms in the corresponding direction until the laser rangefinders and laser reflective targets of the two calibration and measuring mechanisms are on the same horizontal plane;

[0024] If the laser rangefinders and laser reflective targets of the two calibration and measuring mechanisms are not on the same vertical plane parallel to the outer side of the vehicle, adjust the Z-direction adjustment mechanism of one or both calibration and measuring mechanisms in the corresponding direction until the laser rangefinders and laser reflective targets of the two calibration and measuring mechanisms are on the same vertical plane;

[0025] If the extending direction of the measuring mounting rod of the calibration measuring mechanism is not parallel to the horizontal plane, the measuring mounting rod is rotated and adjusted in a corresponding direction by the rotation adjustment mechanism of the calibration measuring mechanism until the extending direction of the measuring mounting rod of the calibration measuring mechanism is parallel to the horizontal plane;

[0026] When measuring the height of a vehicle, a calibration measuring mechanism with a laser rangefinder is selected, the calibration measuring mechanism is placed vertically close to the vehicle, and then fixed to the vehicle through a magnetic suction cup so that the laser rangefinder is located above, and then the laser rangefinder is started for laser ranging.
