Description

Technical Field

[0001] The present invention belongs to the technical field of motor vehicle inspection, and in particular relates to a vehicle correction device and process for a motor vehicle inspection line. Background Art

[0002] The motor vehicle inspection line is an automatic production line that uses modern optomechanical and computer measurement and control technology to test the safety, environmental protection and other performance of road-going motor vehicles. The motor vehicle inspection line includes exhaust gas inspection, lighting inspection, body color inspection, brake performance inspection, vehicle accessories inspection and other inspection items.

[0003] Among them, when conducting lighting inspection on a motor vehicle, the motor vehicle needs to be stationary at a predetermined inspection position, then turn on the headlights, and set up a light-blocking wall at a certain distance from the front of the vehicle. The inspection equipment on the motor vehicle inspection line can detect the lighting performance of the motor vehicle by remotely sensing the light intensity on the light-blocking wall. In the actual operation process, the vehicle is controlled by the driver to drive to the designated inspection position, but due to the differences in driving skills of different drivers, it is difficult to ensure that every driver can align the vehicle. When inspecting some vehicles, the direction of the front of the vehicle cannot be guaranteed to be perpendicular to the light-blocking wall, resulting in the light emitted by the headlights not being able to shine vertically on the light-blocking wall, which will affect the accuracy of lighting inspection.

[0007] As a preferred technical solution of the present invention, the top surface of the vertical plate is arc-shaped, and the intersection of the top surface of the vertical plate and the side wall of the vertical plate is flush with the upper surface of the mounting seat.

[0008] As a preferred technical solution of the present invention, a rubber strip for sealing is fixedly installed at the edge of the bottom surface of the vertical plate, and the rubber strip is tightly fitted to the inner wall of the vertical groove.

[0009] As a preferred technical solution of the present invention, there are several oil pipes, and the control mechanism includes a gear fixedly mounted on the rotating shaft, a control groove is opened on the top surface of the mounting seat, a control rack meshing with the gear is horizontally slidably mounted in the control groove, and two control cylinders are fixedly mounted in the control groove, and the ends of the telescopic sections of the two control cylinders are respectively fixedly connected to the two ends of the control rack.

[0010] As a preferred technical solution of the present invention, a preliminary correction mechanism is arranged on the mounting seat at a position in front of several vertical plates, and the preliminary correction mechanism includes two horizontal axes rotatably mounted on the mounting seat, and the vertical planes where the vertical plates are located are perpendicular to the horizontal axes; each horizontal axis is fixedly mounted with a correction roller coinciding with its axis line, and a correction motor for driving the horizontal axis to rotate is fixedly mounted on the mounting seat.

[0013] The present invention also provides a vehicle correction process for a motor vehicle inspection line, which is completed by using the above-mentioned vehicle correction device for a motor vehicle inspection line, and includes the following steps:

[0014] Step 1: Preliminary correction: Maneuver the vehicle to the position where the wheel and the preliminary correction mechanism correspond, and continue to maneuver the vehicle forward until the wheel rolls to the position between the two correction rollers. Use the preliminary correction mechanism to clean the dirt attached to the wheel surface and perform preliminary correction on the wheel so that the wheel axis is perpendicular to the vertical plate.

[0015] Step 2: Adjust the position: Continue to control the vehicle forward until the wheels squeeze the part of the vertical plate corresponding to its width downward into the vertical groove. At this time, the height of the lifting rod and the inclined plate also change synchronously. In this state, the position of the rotating shaft and the sealing plate is adjusted through the control mechanism to block the oil pipe through the sealing plate.

[0016] Step 3: Correct again: Continue to steer the vehicle forward until the wheels roll to the position between the two inclined plates. Use the two inclined plates to limit the two sides of the wheels, thereby correcting the position of the vehicle to ensure that the front of the vehicle is facing the light-blocking wall when the vehicle is subjected to light inspection.

[0017] The present invention has at least the following beneficial effects: (1) The present invention limits the position of the front wheel of the vehicle by the cooperation of two inclined plates: when the front wheel rolls between the two inclined plates, if there is an angle deviation of the front wheel, the front wheel will inevitably roll toward one of the inclined plates, but because the front wheel has its own gravity and the wheel is affected by the pressure from the vehicle body, the front wheel that rolls onto the inclined plate will inevitably drop back to the surface of the mounting seat, so that the front wheel remains in a state of facing the light-blocking wall. The driver only needs to keep the steering wheel forward to ensure that the front of the vehicle and the front wheel are in the same direction, that is, the front of the vehicle is facing the light-blocking wall, thereby ensuring the accuracy of light detection.

[0018] (2) In the present invention, when the front wheel of the vehicle passes over the vertical plate, the portion of the vertical plate corresponding to the width of the front wheel will drop and squeeze the hydraulic oil in the vertical groove, and the corresponding portion of the hydraulic oil will enter the oil storage tank to push the piston column down, thereby automatically adjusting the height of the inclined plate through the action of oil pressure, and the distance between the two inclined plates on the upper surface of the mounting seat automatically adapts to the width of the front wheel, so that the inclined plate can limit and correct the front wheels of different widths.

[0019] (3) The present invention uses a preliminary correction mechanism to clean the stains attached to the front wheel and makes the table surface of the front wheel fit with the two correction rollers. Since the vertical plane where the vertical plate is located is perpendicular to the axis of the correction roller, the axis of the front wheel is also perpendicular to the vertical plane where the vertical plate is located. In this way, the driver only needs to keep the steering wheel facing the vertical plate to avoid the front wheel from pressing over the vertical plate obliquely, thereby ensuring that the number of vertical plates that descend is consistent with the width of the front wheel.

DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0031] like Figure 1 and Figure 3 As shown, the present embodiment provides a vehicle correction device for a motor vehicle inspection line, comprising a mounting seat 1, the mounting seat 1 is installed underground and the upper surface of the mounting seat 1 is flush with the ground, two lifting rods 2 are vertically slidably installed on the upper surface of the mounting seat 1, and an inclined plate 3 is fixedly installed on the top of each lifting rod 2. A plurality of horizontal rotating rollers 15 are evenly installed on the upper surface of the inclined plate 3 from top to bottom, and the two inclined plates 3 are symmetrically arranged and the distance between the bottom ends of the two inclined plates 3 is less than the distance between the top ends of the two inclined plates 3; the upper surface of the mounting seat 1 is provided with a position corresponding to each inclined plate 3 to allow the inclined plate 3 to be tilted. The inclined plate 3 enters the accommodating groove 101, and a cavity 102 is opened inside the mounting seat 1. The bottom end of the lifting rod 2 extends into the cavity 102, and a horizontal lifting plate 4 is fixedly connected between the bottom ends of the two lifting rods 2. A number of telescopic springs 5 ​​are vertically fixedly installed on the bottom surface of the cavity 102, and the top end of the telescopic spring 5 is fixedly connected to the lifting plate 4; an oil storage tank 6 is fixedly installed on the top surface of the cavity 102, and the oil storage tank 6 is filled with hydraulic oil. A sealing plate 7 is vertically slidably installed in the oil storage tank 6, and a piston column 8 is vertically fixedly installed on the bottom surface of the sealing plate 7, and the bottom end of the piston column 8 is fixedly connected to the lifting plate 4.

[0032] When the vehicle to be tested drives to the position between the two inclined plates 3, if the front wheel is facing the light-blocking wall, the edges on both sides of the front wheel are just in contact with the upper surface of the inclined plates 3, and the wheel remains facing the light-blocking wall; if there is a deviation in the front wheel, the front wheel will roll toward the inclined plate 3 on one side, but because the front wheel itself is affected by gravity and the front wheel is subjected to pressure from the vehicle body, the front wheel that rolls toward the inclined plate 3 on one side returns and drops back to the upper surface of the mounting seat 1, thereby making the front wheel reach the state of facing the light-blocking wall. During the whole process, the driver only needs to keep the steering wheel forward, and the front of the vehicle can reach the state of facing the light-blocking wall synchronously with the front wheel.

[0033] Since the front wheel widths of different vehicles are different, the distance between the upper surface of the mounting seat 1 and the intersection line between the two inclined plates 3 also needs to be consistent with the wheel width, and the inclined plate 3 can be driven to rise or fall by the lifting rod 2; during specific operation, it is necessary to control the hydraulic oil in the oil storage tank 6. When the hydraulic oil in the oil storage tank 6 increases, the hydraulic oil will overcome the elastic force of the telescopic spring 5 to push the sealing plate 7 and the piston column 8 down, the lifting rod 2 and the inclined plate 3 will descend synchronously, and the distance between the upper surface of the mounting seat 1 and the intersection line between the two inclined plates 3 will increase, that is, the wider the front wheel, the more hydraulic oil is needed in the oil storage tank 6; when the hydraulic oil in the oil storage tank 6 decreases, the rebound force of the telescopic spring 5 will push the sealing plate 7 and the piston column 8 up, the lifting rod 2 and the inclined plate 3 will rise synchronously, and the distance between the upper surface of the mounting seat 1 and the intersection line between the two inclined plates 3 will also decrease.

[0034] like Figure 4 , Figure 5 and Figure 6 As shown, a plurality of vertical plates 9 are installed at a position in front of the receiving groove 101 on the upper surface of the mounting seat 1, and the plurality of vertical plates 9 are evenly arranged in the left-right direction. A vertical groove 103 that slides with the vertical plate 9 is opened at a position corresponding to each vertical plate 9 on the upper surface of the mounting seat 1. A reset spring 10 is fixedly connected between the bottom surface of the vertical groove 103 and the vertical plate 9. The reset spring 10 is a compression spring and cannot be stretched. The top surface of the vertical plate 9 is an arc shape, and the intersection position of the top surface of the vertical plate 9 and the side wall of the vertical plate 9 coincides with the mounting seat. 1 is flush with the upper surface; a rubber strip 16 for sealing is fixedly installed at the bottom edge of the vertical plate 9, and the rubber strip 16 is tightly fitted with the inner wall of the vertical groove 103; an oil cavity 104 is opened inside the mounting seat 1, and a through groove 105 connected with the oil cavity 104 is opened on the bottom surface of the vertical groove 103; a plurality of oil pipes 11 connected with the oil cavity 104 and the oil storage tank 6 are fixedly installed inside the mounting seat 1; a rotating shaft 12 is rotatably installed in the oil pipe 11, and a sealing sheet 13 is fixedly installed on the rotating shaft 12, and the sealing sheet 13 can control the on and off of the oil pipe 11.

[0035] When the front wheel presses over the vertical plate 9, front wheels of different widths will cause different numbers of vertical plates 9 to descend. When the vertical plates 9 descend, they will squeeze the hydraulic oil in the vertical grooves 103. After being squeezed, the hydraulic oil enters the oil chamber 104 through the through grooves 105 and enters the oil storage tank 6 through the oil pipe 11. The wider the front wheel, the more vertical plates 9 will descend, that is, the more hydraulic oil will enter the oil storage tank 6, thereby achieving the effect of automatic lifting of the two inclined plates 3 according to the width of the front wheel. It should be noted that since the return spring 10 is a compression spring, it cannot be pulled Therefore, when the vertical plate 9 descends, only the hydraulic oil in the corresponding vertical groove 103 will be squeezed into the oil pipe 11, and the hydraulic oil will not flow back to other vertical grooves 103, thereby ensuring the accuracy of the rising height of the inclined plate 3; when the wheel presses on the vertical plate 9, the sealing plate 13 is driven to rotate by rotating the rotating shaft 12. After the sealing plate 13 seals the oil pipe 11, the hydraulic oil cannot flow freely in the oil pipe 11, that is, the amount of hydraulic oil in the oil storage tank 6 remains unchanged, and the lifting rod 2 and the inclined plate 3 can be maintained at a constant height.

[0036] like Figure 2 As shown, a control mechanism 14 for controlling the rotating shaft 12 is installed on the mounting base 1, and the control mechanism 14 includes a gear 1401 fixedly installed on the rotating shaft 12. A control groove 106 is opened on the top surface of the mounting base 1, and a control rack 1402 meshing with the gear 1401 is horizontally slidably installed in the control groove 106, and two control cylinders 1403 are fixedly installed in the control groove 106, and the ends of the telescopic sections of the two control cylinders 1403 are respectively fixedly connected to the two ends of the control rack 1402; when the wheel presses on the vertical plate 9, the control rack 1402 is controlled by the control cylinder 1403 to move horizontally, and the control rack 1402 drives the gear 1401 to rotate, and the gear 1401 drives the rotating shaft 12 and the sealing plate 13 to rotate, so that the oil pipe 11 can be turned on and off.

[0037] like Figure 1 , Figure 2 and Figure 7As shown, a preliminary correction mechanism 17 is provided on the mounting seat 1 at a position in front of several vertical plates 9, and the preliminary correction mechanism 17 includes two horizontal shafts 1701 rotatably mounted on the mounting seat 1, and the vertical surface where the vertical plate 9 is located is perpendicular to the horizontal shafts 1701; a correction roller 1702 coincident with its axis is fixedly mounted on each horizontal shaft 1701, and a correction motor 1703 for driving the horizontal shaft 1701 to rotate is fixedly mounted on the mounting seat 1; a plurality of strip grooves 1704 are evenly arranged on the surface of the correction roller 1702 along its circumference; a cleaning shaft 1705 parallel to the horizontal shaft 1701 is rotatably mounted on the mounting seat 1, and the cleaning shaft 1705 is located in the middle and lower position of the two correction rollers 1702; a cleaning motor 1706 for driving the cleaning shaft 1705 to rotate is fixedly mounted on the mounting seat 1; the cross section of the cleaning shaft 1705 It is cross-shaped and a sleeve 1707 is movably mounted on the cleaning shaft 1705, a cleaning spring 1708 is fixedly connected between the end of the cleaning shaft 1705 and the inner end surface of the sleeve 1707; a plurality of brush rollers 1709 are evenly and fixedly mounted on the sleeve 1707 along its axial direction; the end of the sleeve 1707 extends to the outside of the mounting seat 1, and a circular plate 1710 coincident with its axis is fixedly mounted on the end of the sleeve 1707, a plurality of first magnet blocks 1711 are evenly and fixedly mounted on the surface of the circular plate 1710 along its circumference, a fixed plate 1712 parallel to the circular plate 1710 is mounted on the mounting seat 1, and a plurality of second magnet blocks 1713 are evenly and fixedly mounted on the surface of the fixed plate 1712 around the sleeve 1707; a strip-shaped material receiving box 1714 parallel to the cleaning shaft 1705 is movably mounted at a position below the cleaning shaft 1705 on the mounting seat 1.

[0038] If the driver directly controls the vehicle to pass over the vertical plate 9, the axis of the front wheel may not be able to remain perpendicular to the vertical plane where the vertical plate 9 is located, that is, the front wheel may obliquely pass over the vertical plate 9, which will cause the vertical plate 9 that does not correspond to the width of the front wheel to be squeezed down by the front wheel (the number of vertical plates 9 that actually descend is greater than the number of vertical plates 9 that correspond to the width of the front wheel). This will cause the lifting rod 2 and the inclined plate 3 to descend to a height greater than the height they should descend, resulting in the distance between the upper surface of the mounting seat 1 and the intersection line of the two inclined plates 3 being too wide, and the two inclined plates 3 cannot play a role in limiting the front wheel. Therefore, before the front wheel contacts the vertical plate 9, the front wheel needs to be preliminarily corrected by the preliminary correction mechanism 17 so that the axis of the front wheel is aligned with the vertical plate 9 where the vertical plate 9 is located. The vertical surface remains vertical; the working principle of the preliminary correction mechanism 17 is as follows: the driver keeps the steering wheel in the forward direction and drives the vehicle forward until the front wheel flips over one of the correction rollers 1702 and falls between the two correction rollers 1702. Since the front wheel tends to reach a stable state, that is, the tread of the front wheel will eventually fit with the two correction rollers 1702, and the vertical surface where the vertical plate 9 is located is perpendicular to the axis of the correction roller 1702, the axis of the front wheel will also be perpendicular to the vertical surface where the vertical plate 9 is located. In this state, the driver keeps the steering wheel in the forward direction and drives the vehicle forward until the front wheel flips over the other correction roller 1702. The driver keeps the steering wheel in the forward direction and drives the vehicle forward, and the front wheel can be guaranteed to press over the vertical plate 9 in the correct state.

[0039] In the actual inspection process, there are often stains such as mud attached to the wheels. If these stains are not removed, it will affect the fit between the front wheel and the two correction rollers 1702, that is, the axis of the front wheel cannot be in a perpendicular state to the vertical plane where the vertical plate 9 is located; when the front wheel falls between the two correction rollers 1702, the correction roller 1702 is driven to rotate by the correction motor 1703, and the edges of the strip groove 1704 will clean the stains attached to the front wheel. Some of the stains will fall directly to the upper surface of the mounting seat 1, and some of the stains will enter the strip groove 1704; the cleaning shaft 1705 is driven to rotate by the cleaning motor 1706, and the cleaning shaft 1705 drives the shaft sleeve 1707, the brush roller 1709, the circular plate 1710 and the first magnet block 1711 to rotate synchronously. When the brush roller 1709 rotates, the stains in the strip groove 1704 are swept into the strip receiving box 1714; at the same time, a mutual repulsive force is intermittently generated between the first magnet block 1711 and the second magnet block 1713. The mutual repulsive force and the rebound force of the cleaning spring 1708 work together to make the shaft sleeve 1707, the brush roller 1709, the circular plate 1710 and the first magnet block 1711 move back and forth along the axial direction, thereby improving the cleaning effect of the brush roller 1709 on the stains in the strip groove 1704.

[0040] This embodiment also provides a vehicle correction process for a motor vehicle inspection line, which is completed by using the above-mentioned vehicle correction device for a motor vehicle inspection line, and includes the following steps:

[0041] Step 1, preliminary correction: control the vehicle to the position where the wheel corresponds to the preliminary correction mechanism 17, and continue to control the vehicle forward until the wheel rolls to the position between the two correction rollers 1702, clean the dirt attached to the wheel surface through the preliminary correction mechanism 17, and perform preliminary correction on the wheel so that the wheel axis is perpendicular to the vertical plate 9.

[0042] Step 2, adjust the position: continue to control the vehicle forward until the wheel squeezes the part of the vertical plate 9 corresponding to its width downward into the vertical groove 103, at which time the height of the lifting rod 2 and the inclined plate 3 also changes synchronously; in this state, the position of the rotating shaft 12 and the sealing plate 13 is adjusted by the control mechanism 14, and the oil pipe 11 is blocked by the sealing plate 13.

[0043] Step 3: Correct again: Continue to control the vehicle forward until the wheels roll to the position between the two inclined plates 3, and limit the two sides of the wheels through the two inclined plates 3, so as to correct the position of the vehicle and ensure that the front of the vehicle is facing the light blocking wall when the vehicle is tested for light.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
