Detailed Description
As shown in fig. 1-9, an automobile rear collision-prevention Liang Bianjie detection device comprises a base 1, wherein supporting legs 101 are fixed at four corners of the lower end of the base 1.
The base 1 is provided with a through hole 103, a vertical limiting plate 201 is connected in a sliding manner in the through hole 103, and the upper end of the limiting plate 201 is fixedly connected with the lower end of the bearing plate 2. The upper end of the base 1 is fixedly provided with a plurality of vertically arranged springs 204, the lower ends of the springs 204 are fixedly connected with the base 1, and the upper ends of the springs 204 are fixedly connected with the lower ends of the bearing plates 2.
Both sides of the upper end of the bearing plate 2 are provided with position adjusting devices.
The position adjusting device comprises a motor 4 fixedly connected with the bearing plate 2, and the motor 4 is vertically arranged. A driving wheel 401 is fixed on the output shaft of the motor 4, a driven wheel 402 is rotatably connected on the bearing plate 2, and the driving wheel 401 and the driven wheel 402 are in transmission connection through a belt 403. A plurality of push blocks 404 are fixed at equal intervals on the outer side of the belt 403.
The base 1 is fixedly provided with a support frame 102, the bearing plate 2 is positioned in the support frame 102, and a positioning mechanism is arranged on the bearing plate 2 at one side of the position adjusting device.
The positioning mechanism comprises a sliding hole 202 formed in the bearing plate 2, a positioning plate 3 is connected in a sliding manner in the sliding hole 202, and the lower end of the positioning plate 3 is in contact with the upper end of the base 1. The upper end of the positioning plate 3 is provided with a U-shaped groove 301, and two opposite side walls of the U-shaped groove 301 are inclined planes. The distance between the upper ends of the two inclined planes is larger than the distance between the lower ends of the two inclined planes, and the distance between the lower ends of the two inclined planes is smaller than the width of the rear anti-collision beam 6. The wall of the sliding hole 202 is provided with a vertical sliding groove 203, a sliding block 302 is in sliding clamping connection with the sliding groove 203, and the sliding block 302 is fixedly connected with the positioning plate 3.
The upper end of the supporting frame 102 is provided with a detection device.
The detection device comprises a hydraulic rod 5 fixed on a support frame 102, a connecting plate 501 is fixed on a telescopic rod of the hydraulic rod 5, inclined grooves 502 are formed in two ends of the connecting plate 501, a rotating shaft 503 is fixed in the inclined grooves 502, and the upper end of a push rod 504 is rotationally connected with the rotating shaft 503. The lower end of the push rod 504 is rotatably provided with a ball 505. The torsion spring is sleeved on the rotating shaft 503, one end of the torsion spring is fixedly connected with the push rod 504, and the other end of the torsion spring is fixedly connected with the rotating shaft 503. The two push rods 504 are symmetrically arranged according to the axis of the hydraulic rod 5. The distance between the lower ends of the push rods 504 is greater than the distance between the upper ends of the push rods 504. A plurality of detection blocks 506 are fixed at the lower end of the connecting plate 501 between the two push rods 504.
The rear impact beam 6 to be detected is placed on the carrier plate 2. The lower side of the rear anti-collision beam 6 to be detected is matched with the upper side of the bearing plate 2. At this time, the rear bumper beam 6 can only move forward and backward on the carrier plate 2, the upper end of the positioning plate 3 is positioned in the slide hole 202, and the end of the rear bumper beam 6 is offset from the push block 404 on the belt 403 on one side thereof. The motor 4 is started to drive the driving wheel 401 to rotate, the driving wheel 401 drives the driven wheel 402 to rotate through the belt 403, the pushing block 404 on the belt 403 moves, and the pushing block 404 on the belt 403, which is in contact with the rear anti-collision beam 6, can push the rear anti-collision beam 6 to be detected to move towards the sliding hole 202. When the rear impact beam 6 moves over the slide hole 202, the motor 4 stops rotating.
Subsequently, the hydraulic rod 5 is extended, the hydraulic rod 5 pushes the connecting plate 501 to move downwards, and after the balls 505 contact the upper side of the rear bumper beam 6, since the elasticity of the torsion spring is greater than that of the spring 204, as the hydraulic rod 5 is extended, the push rod 504 pushes the bearing plate 2 through the balls 505 to compress the spring 204 to move downwards. In the descending process of the bearing plate 2, the lower end of the positioning plate 3 is blocked by the base 1, and in the descending process of the bearing plate 2, the positioning plate 3 moves upwards along the sliding hole 202 relative to the bearing plate 2. After the inclined plane in the U-shaped groove 301 at the upper end of the positioning plate 3 is contacted with the rear anti-collision beam 6, the rear anti-collision beam 6 can move on the bearing plate 2 under the guiding action of the inclined plane. When the lower ends of the two inclined planes in the U-shaped groove 301 at the upper end of the positioning plate 3 are in contact with the rear anti-collision beam 6, the rear anti-collision beam 6 is positioned at a designed position on the bearing plate 2. Under the blocking action of the positioning plate 3 on the rear anti-collision beam 6, the rear anti-collision beam 6 cannot continue to move downwards.
As the hydraulic rod 5 drives the connecting plate 501 to continue to move downwards, the lower ends of the two push rods 504 are away from each other because the bearing plate 2 cannot move downwards, the torsion springs deform and store force, and when the detection block 506 can be inserted into the mounting hole 602 on the rear anti-collision beam 6, the mounting hole 602 of the rear anti-collision beam 6 is proved to meet the requirements. If the test block 506 cannot be inserted into the mounting hole 602 on the rear impact beam 6, the machined mounting hole 602 of the rear impact beam 6 is proved to be unsatisfactory.
Along with the continuous descending of the connecting plate 501 driven by the hydraulic rod 5, when one ball 505 contacts with the inclined part 601 of the rear anti-collision beam 6 on one side of the connecting plate, the position of the other ball 505 is observed, and when the other ball 505 contacts with the inclined part 601 of the rear anti-collision beam 6 on one side of the connecting plate, the bending position of the rear anti-collision beam 6 is proved to meet the processing requirement.
When one ball 505 is in contact with the inclined portion 601 of the rear impact beam 6 on one side thereof, the other ball 505 is not in contact with the inclined portion 601 of the rear impact beam 6 on one side thereof, and the bending position of the rear impact beam 6 proves to be unsatisfactory.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
