Referring to fig. 1-3, an automobile rear cross beam detection device comprises a mounting plate 1, a test rod 2, a driving mechanism 3, a frame 4 and a clamp 5.
As shown in fig. 1, two slide rails 41 are arranged at the top of the frame body 4, the mounting plate 1 is provided with a mounting surface 11 and a connecting surface 12, and the mounting surface 11 is vertically arranged at the top of the connecting surface 12, so that the mounting plate 1 is in an L shape as a whole; the bottom of the connecting surface 12 is provided with two sliding grooves, and the distance between the two sliding grooves is equal to the distance between the two sliding rails 41, so that the two sliding rails 41 can be respectively assembled in the two sliding grooves; the slide rail 41 plays a role in limiting and guiding in the sliding of the mounting plate 1, and ensures that the mounting plate 1 slides stably.
The fixture 5 is arranged on the mounting plate 1 and is used for clamping the automobile rear cross beam, so that the automobile rear cross beam is prevented from shifting in the detection process. The clamp 5 in this embodiment may be a flexible clamping jaw or others, and this embodiment is not limited thereto.
As shown in fig. 1 and 3, the driving mechanism 3 includes a telescopic rod 31 and a link; wherein the connecting piece comprises a first rack 32, a second rack 33 and a gear 34; the first rack 32 is arranged at the bottom of the connecting surface 12, the second rack 33 is arranged at the top of the frame body 4, and the projections of the first rack 32 and the second rack 33 on the horizontal plane are overlapped; the telescopic rod 31 is fixed at the top of the frame body 4, the piston end of the telescopic rod is rotationally connected with the gear 34, the gear 34 is meshed with the first rack 32 and the second rack 33, when the telescopic rod 31 stretches or shortens, the gear 34 rotates on the first rack 32, and the second rack 33 drives the connecting surface 12 to advance or retreat along the sliding rail 41; by providing the connecting piece, the stroke can also be increased.
In this embodiment, the telescopic rod 31 is preferably a hydraulic rod.
As shown in fig. 1 and fig. 2, the mounting surface 11 is provided with a plurality of protrusions 111, and the test bars 2 are respectively arranged on the protrusions 111; specifically, the test lever 2 includes a first lever body 21, a second lever body 22, a first spring 23, a second spring 24, a first pressure sensor 25, and a second pressure sensor 26.
The first rod body 21 is slidably arranged on the protrusion 111, and the second rod body 22 is sleeved on the first rod body 21; two ends of the first spring 23 are respectively connected with the protrusion 111 and the inner wall of the first rod body 21, and two ends of the second spring 24 are respectively connected with the end part of the first rod body 21 and the inner wall of the second rod body 22; the first pressure sensor 25 is provided on the boss 111, and the second pressure sensor 26 is provided on the inner wall of the first rod body 21.
As the driving mechanism 3 drives the mounting plate 1 to move, when the second rod body 22 contacts the inner wall of the hole point, the second rod body 22 is compressed, and as the depth of the hole point is increased, when the second rod body 22 is compressed to the limit, the second rod body 22 drives the first rod body 21 to slide in the protrusion 111; as the mounting plate 1 moves to a fixed position, there are three situations:
the hole points meet the design requirements: at this time, the bottom of the second rod 22 contacts the second pressure sensor 26, and the bottom of the first rod 21 does not contact the first pressure sensor 25.
The pore point is too shallow: at this time, the bottom of the second rod 22 contacts the second pressure sensor 26, and the bottom of the first rod 21 contacts the first pressure sensor 25.
The hole point is too deep: at this time, the bottom of the second rod 22 is not in contact with the second pressure sensor 26.
In this embodiment, the device further includes terminals electrically connected to the first pressure sensors 25 and the second pressure sensors 26, respectively; the pressures detected by the first pressure sensor 25 and the second pressure sensor 26 are transmitted to the terminals, respectively, and are judged by the terminals.
The following is the case at this time:
the first pressure sensor 25 detects a value, and the second pressure sensor 26 does not detect a value: at this time, the description hole points meet the design requirements.
The first pressure sensor 25 and the second pressure sensor 26 each detect a value: at this point, the hole point is too shallow.
No value is detected by either the first pressure sensor 25 or the second pressure sensor 26: at this point, the hole point is too deep.
Through the analysis, whether the depth of each hole point of the automobile rear cross beam detection device meets the design requirement can be judged very quickly; meanwhile, the sliding distance between the first rod 21 and the protrusion 111 is within the allowable error range of design, i.e. the depth satisfies the design requirement at the inner hole point in the area. The first spring 23 and the second spring 24 serve to restore the first rod body 21 and the second rod body 22.
It should be noted that, the friction force between the second rod 22 and the first rod 21 is smaller than the friction force between the first rod 21 and the protrusion 111, so that when the second rod 22 abuts against the inner wall of the hole point, the second rod 22 slides in the first rod 21, and when the second rod 22 reaches the dead point, the second rod 22 drives the first rod 21 to slide in the protrusion 111, thereby avoiding the situation that the first rod 21 and the second rod 22 are compressed together.
It should be noted that, in this embodiment, the positions of the test lever 2 and the protrusion 111 are designed according to the position of the hole point of the rear beam of the automobile in actual production, that is, the axis of one test lever 2 and the axis of one protrusion 111 coincide with the axis of the hole point of one rear beam.
It should be noted that the diameter of the hole point is larger than the diameters of the protrusion 111, the first rod 21, and the second rod 22, so that the test rod 2 enters the hole point.
It should be noted that, the electrical signal connection between the terminal and the plurality of first pressure sensors and the plurality of second pressure sensors is the prior art, and meanwhile, the signal analysis mode of the terminal to the first pressure sensors and the second pressure sensors is the prior art; none of the above are modifications of the present embodiment, which are not described in detail herein.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
