The workbench 2 is provided with a second driving component for driving the limiting unit at the rear side to move. The two second driving components are in one-to-one correspondence with the two limiting units at the rear side.
The second driving assembly comprises a first motor 10, a screw 9 and a second motor 14. Two fixing plates 16 are fixedly arranged on the workbench 2, the screw rod 9 is rotatably connected between the two fixing plates 16, and the axis of the screw rod 9 is horizontally arranged front and back. A slide bar 17 is fixedly connected between the two fixing plates 16, and the slide bar 17 is parallel to the fixing plates 16. The connecting block 12 is in threaded connection with the screw rod 9, a sliding hole matched with the sliding rod 17 is formed in the connecting block 12, and the connecting block 12 is in sliding connection with the sliding rod 17 through the sliding hole.

The connecting block 12 is hinged with a connecting rod 13, the connecting rod 13 is horizontally arranged, and one end of the connecting rod 13 far away from the connecting block 12 is fixedly connected with the corresponding connecting plate 6. The second motor 14 is fixedly installed on the connecting block 12, and a motor shaft of the second motor 14 is vertically downward and fixedly connected with the connecting rod 13.
Working principle: initially, the cylinder 7 is in a shortened state, two blocking blocks 5 in two limiting units on the rear side are opposite, and the connecting block 12 is positioned in the direction of the sliding rod 17 approaching the slope 1. The second guide 4 is engaged with the two first guides 3 in the front-rear direction.
In use, the car is driven onto the table 2 via the ramp 1 and its wheels are stopped on the rotating platform 8 and the wheels are aligned. The two front wheels are in one-to-one correspondence with the two limiting units on the front side. At this time, the vehicle body is directed at a certain inclination with respect to the longitudinal direction of the second guide 4 due to the manual parking, but the inclination angle is small.
Then four electric slide rails 31 are started simultaneously, the electric slide blocks drive the telescopic rods 30 through the mounting plates to enable the limiting units on the front sides to move towards the direction close to the front wheels, the blocking blocks 5 contact the front wheels and squeeze the front wheels, the electric slide blocks drive the mounting blocks to move towards the direction close to the front wheels, the telescopic rods 30 are shortened, and the springs 29 are compressed. When the spring 29 is compressed to some extent, the electric slide rail 31 is closed. The blocking piece 5 presses the front wheel of the vehicle so that the corresponding first pressure sensor 18 has a certain pressure reading.
As a result of the inclination of the vehicle body, one of the blocking pieces 5 is brought into contact with the front wheel of the vehicle. So that the reading of the corresponding first pressure sensor 18 is greater. If the reading of the first pressure sensor 18 on the left is greater than the reading of the first pressure sensor 18 on the right, this indicates that the vehicle body is tilted to the right, causing the rotary platform 8 to rotate counterclockwise. Specifically, the third motor 23 is started, and the third motor 23 drives the rotary platform 8 to rotate through the second gear 22 and the inner gear ring 20.
The rotating platform 8 drives the automobile to rotate anticlockwise. The front left side of the vehicle body is offset backwards, and the limiting unit on the front left side moves towards the front left wheel under the action of the corresponding spring 29, so that the blocking block 5 on the front left side keeps contact with the front left wheel. The reading of the first pressure sensor 18 on the front left gradually decreases. At the same time, the front right side of the vehicle body is offset forwards, and the blocking block 5 on the front right side is further pressed, so that the reading value of the first pressure sensor 18 on the front right side is gradually increased. When the reading of the left first pressure sensor 18 is equal to the reading of the right first pressure sensor 18, the body is aligned, i.e. the axis of the vehicle chassis is parallel to the second guide 4.
Similarly, if the reading value of the first pressure sensor 18 on the right side is greater than the reading value of the first pressure sensor 18 on the left side, it is indicated that the vehicle body is tilted to the left, so that the rotary platform 8 is rotated clockwise, and the vehicle body is further aligned.
Then two cylinders 7 are started simultaneously, the telescopic ends of the cylinders 7 are close to corresponding vertical plates until the telescopic ends of the cylinders 7 are in contact with the corresponding vertical plates, the second pressure sensor has a certain reading value, and at the moment, the front wheels of the automobile are limited by the limiting units on the front sides, so that the automobile is prevented from moving forward accidentally.
There may be an offset in the centre of the vehicle chassis relative to the centre of the rotary platform 8 due to parking. The distance between the center of the vehicle chassis and the second guide 4 should be controlled under the influence of the detection range of the detection head 11. When the vehicle is being swung, there may be a certain deviation of the axis of the vehicle chassis from the second guide 4, i.e. the axis of the vehicle chassis does not coincide with the axis of the second guide 4. As shown in fig. 5, a circle M is drawn around the center of the rotary table 8. When the vehicle is being swung, the deviation of the axis of the vehicle chassis relative to the second guide 4, i.e. the distance of the axis of the vehicle chassis from the second guide 4 is smaller than the radius of the circle M, can be detected normally in this range. Thus, the center of the vehicle chassis is located within the circle M when parking.
Then, the second motor 14 is started, the second motor 14 drives the connecting rod 13 to rotate, the rear limiting unit rotates in a direction approaching to the rear wheel, and when the rear limiting unit is opposite to the rear wheel, the second motor 14 is closed, and the first motor 10 is started. The first motor 10 drives the screw rod 9 to rotate, so that the connecting block 12 slides inwards along the sliding rod 17, and the limiting unit slides towards the direction close to the rear wheel until the limiting unit at the rear side abuts against the rear wheel. At this time, four wheels of the automobile are fixed, so that the influence of unexpected movement of the automobile on a detection result in the testing process is avoided.
After that, the detection head 11 and the fifth motor 26 are started. The fifth motor 26 drives the first gear 15 to rotate, under the action of the rack, the first gear 15 moves along the rack, and meanwhile, the guide block 27 slides along the first guide groove and the second guide groove, so that the detection head 11 moves back and forth along the first guide piece 3 and the second guide piece 4, and the length direction of the automobile chassis is detected.
When the detection in the longitudinal direction of the automobile is completed, the detection head 11 is moved onto the second guide 4. Then the fourth motor 25 is started, and the fourth motor 25 drives the second guide piece 4 to rotate, so that two ends of the second guide piece 4 are respectively matched with the first guide pieces 3 on the left side and the right side. The detection head 11 and the fifth motor 26 are started again, and the detection head 11 is moved laterally to detect the vehicle chassis in the width direction.
Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
