It should be noted that the device driving the lifting part 11 is not limited to the hydraulic rod, for example, a cylinder.

[0029] The baffle plate includes a first baffle plate 13 and a second baffle plate 14 which are arranged opposite to each other along the length direction of the fixing portion 12 . The first baffle plate 13 is perpendicular to one of the fixing portions 12 , and the second baffle plate 14 is perpendicular to the other fixing portion 12 .

[0030] The linear drive unit is connected to the first baffle 13 and the second baffle 14, and is used to drive the first baffle 13 and the second baffle 14 to move closer to or away from each other along the length direction of the fixed part 12. The width of the lifting part 11 is smaller than the width of the fixed part 12. A slide groove 121 is arranged along the length direction of the fixed part 12. The first baffle 13 and the second baffle 14 are both slidably arranged in the slide groove 121. For example, the linear drive unit includes a first ball screw 16 and a second ball screw 17. The first ball screw 16 drives the first baffle 13 to perform linear motion along the length direction of the fixed part 12, and the second ball screw 17 drives the second baffle 14 to perform linear motion along the length direction of the fixed part 12.

[0031] One of the laser distance measuring units 30 is used to measure the distance between the first baffle 13 and the second baffle 14 . For example, the laser distance measuring unit 30 may be disposed on the first baffle 13 or the second baffle 14 .

[0032] Another laser ranging unit 30 is used to measure the distance between the lifting part 11 of the base 10 and the platform 20. For example, the laser ranging unit 30 can be set on the lifting part 11 of the base 10, and can also be set on the platform 20. Preferably, the laser ranging unit 30 is set on the platform 20 to avoid damage to the laser ranging unit 30 set on the lifting part 11 caused by automobile parts placed on the lifting part 11.

[0033] When it is necessary to measure the height and length of an automobile part, the automobile part is placed on the lifting portion 11 of the base 10. At this time, the platform 20 descends to the upper surface of the automobile part, and the linear drive unit drives the first baffle 13 and the second baffle 14 to move toward the automobile part. The first baffle 13 and the second baffle 14 are moved to the surface of the automobile part. At this time, the two laser ranging units 30 respectively measure the distance between the first baffle 13 and the second baffle 14, and the distance between the lifting portion 11 of the base 10 and the platform 20. When it is necessary to measure the length of automobile parts at different heights, the lifting drive unit 18 drives the lifting part 11 to drive the automobile parts placed on the lifting part 11 to descend to a position, and then the platform 20 descends to the upper surface of the automobile parts, and the linear drive unit drives the first baffle 13 and the second baffle 14 to move toward the automobile parts. The first baffle 13 and the second baffle 14 are moved to the surface of the automobile parts. At this time, the laser ranging unit 30 measures the length of the automobile parts at this height. Such an arrangement can not only detect the height and length of automobile parts, but also detect the length of automobile parts at different heights, thereby increasing the dimension of detection. In addition, by measuring the size of automobile parts with a laser rangefinder, the deviation caused by the operator's visual readings is reduced.

[0034] In another embodiment, a guide rod 21 is further included, the platform 20 is sleeved on the guide rod 21, a guide groove is provided along the length direction of the surface of the guide rod 21, the platform 20 is slidably arranged in the guide groove, and the platform 20 slides along the guide groove through a slider, which has better stability, and the scale lines 211 on the guide rod 21 will not be worn due to the up and down movement of the platform 20. Preferably, the number of guide rods 21 is at least 2, and the two guide rods 21 are arranged opposite to each other along the length direction of the platform 20, so as to further increase the stability of the platform 20 when it moves.

[0035] In another embodiment, the platform 20 is provided with a level meter 23 , by which it can be determined whether the platform 20 is tilted, so as to avoid measurement deviation caused by the tilt of the platform 20 .

[0036] In another embodiment, a laser displacement meter 122 is provided on the lifting part 11 to measure the height of the automobile parts being lowered to determine the position of the automobile parts to be measured in length, thereby further improving the accuracy of the measurement. It should be noted that the laser displacement meter 122 is not limited to being provided on the lifting part. For example, the laser displacement meter 122 is provided on the platform 20. When it is necessary to detect the height of the automobile parts placed on the lifting part 11, the platform 20 is lowered to the surface of the automobile parts. The position of the platform 20 at this time is used as the initial position for measuring the displacement of the automobile parts. The laser displacement meter 122 is turned on, and the lifting part 11 drives the automobile parts to descend to a position. The platform 20 is lowered to the surface of the automobile parts again. At this time, the displacement measured by the laser displacement meter 122 is the height of the automobile parts being lowered.

[0037] In another embodiment, a metering line 15 is provided along the length direction of the base on the side of the base facing the operator. When the laser ranging unit 30 fails and cannot measure the distance, the operator can visually read the height and length direction of the automobile parts as an emergency detection method to avoid detection stagnation.
