Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality" means two or more unless otherwise specifically defined.

[0041] The following will describe the embodiments of the present utility model in detail with reference to the drawings.

[0042] Embodiment:

[0043] Refer to Figures 1-4 , this embodiment discloses a detection device for automobile parts, including a base frame 10, guide rails 20, pressing rods 30, a first driving member 40 and a measuring assembly 50.

[0044] Specifically, two guide rails 20 with a spacing are arranged on the base frame 10. The two guide rails 20 are arranged parallel to each other and are both arranged in the horizontal direction.

[0045] Between the two guide rails 20, two pressing rods 30 are arranged. The two pressing rods 30 are distributed along the length direction of the guide rails 20. At the same time, the bottom ends of the two pressing rods 30 are rotatably arranged on the base frame 10, and the top ends of the two pressing rods 30 can be arranged in the vertical direction.

[0046] The driving part of the first driving member 40 is power-connected to the bottom ends of the two pressing rods 30 and is used to drive the two pressing rods 30 to rotate on the base frame 10. In addition, the rotation connection points of the two pressing rods 30 and the base frame 10 are located below the guide rails 20, so that when the first driving member 40 drives the two pressing rods 30 to rotate, the top ends of the two pressing rods 30 can rotate to below the tracks.

[0047] The measuring assembly 50 has two clamping plates 51 respectively arranged on both sides of the guide rails 20. The distances between the two clamping plates 51 and the two guide rails 20 are the same, and the two clamping plates 51 can move closer to or away from each other under the drive of a second driving member 52. At the same time, the distance between the two clamping plates 51 can be measured.

[0048] In this technical solution, the bumper to be detected is placed on the two guide rails 20, and the first driving member 40 directly drives the top ends of the two pressing rods 30 to approach each other, and then the bumper is clamped from both sides. Then, the second driving member 52 is used to drive the two clamping plates 51 to approach each other, so that the two clamping plates 51 respectively clamp the bumper from both ends.

[0049] By calculating the distance between the two clamping plates 51, the measurement of the length dimension of the bumper can be realized, and by measuring the distance between the two pressing rods 30, the measurement of the width dimension of the bumper can be realized. This technical solution provides a device that can detect the bumper in small batches.

[0050] In one specific embodiment:

[0051] One end of the pressing rod 30 rotatably connected to the base frame 10 is provided with a connecting rod 31. The included angle between the length direction of the connecting rod 31 and the length direction of the pressing rod 30 is less than 180° (generally an included angle of 135°). The connecting rod 31 has a first chute 32 inside. The first chute 32 is strip-shaped and is arranged along the length direction of the connecting rod 31.

[0052] A connecting rod 31 is provided on each of the two compression bars 30, and the two connecting rods 31 are arranged oppositely and are distributed in a state of approaching each other relative to the two compression bars 30.

[0053] Among them, the driving end of the first driving member 40 is arranged in the first sliding groove 32. The driving end of the first driving member 40 can move in the vertical direction. In cooperation with the sliding of the driving end in the first sliding groove 32, the connecting rod 31 drives the compression bar 30 to rotate on the base frame 10.

[0054] Preferably, the first driving member 40 includes a driving rod 41, a movable rod 42, a first screw 43 and a first motor 44. Among them, a second sliding groove 45 is provided at each end of the driving rod 41. The length directions of the two second sliding grooves 45 are the same as the length direction of the driving rod 41, and the two second sliding grooves 45 are symmetrically distributed.

[0055] A movable rod 42 is slidably arranged in each of the two second sliding grooves 45, and the two movable rods 42 also respectively pass through the first sliding groove 32 on a connecting rod 31.

[0056] In addition, a threaded hole is provided in the middle of the driving rod 41. The first screw 43 is threadedly matched with the threaded hole. The top end of the first screw 43 is rotatably arranged on the base frame 10, and the bottom end of the first screw 43 is power-connected to the output shaft of the first motor 44 (generally, the power connection method includes direct coaxial connection between the end of the first screw 43 and the end of the output shaft of the first motor 44, or the end of the first screw 43 is connected to the end of the output shaft of the first motor 44 through a gear set).

[0057] In this embodiment, the first motor 44 drives the first screw 43 to rotate, and then through the threaded cooperation relationship between the first screw 43 and the driving rod 41, the up and down movement of the driving rod 41 is realized, so as to drive the rotation of the connecting rod 31 and the compression bar 30 through the movable rod 42 slidably arranged in the first sliding groove 32 and the second sliding groove 45.

[0058] Preferably, the two ends of the driving rod 41 are slidably arranged on the base frame 10. Specifically, sliding ways matching the two ends of the driving rod 41 are provided on both sides of the base frame 10.

[0059] In another specific embodiment:

[0060] Four compression bars 30 are provided between the two guide rails 20. A connecting rod 31 is provided on each compression bar 30. The four compression bars 30 are grouped in pairs and are respectively close to the two guide rails 20.

[0061] Both ends of the same movable rod 42 are slidably arranged in the first sliding groove 32 on a connecting rod 31, so that when the two movable rods 42 move, the four compression bars 30 can move synchronously.

[0062] In this embodiment, by providing four pressing rods 30, the bumper can be clamped at four points on both sides thereof.

[0063] In another specific embodiment:

[0064] The measuring assembly 50 further includes a guide rod 53. The middle part of the guide rod 53 is provided on the base frame 10.

[0065] The guide rod 53 is horizontally arranged above the guide rail 20 and is perpendicular to the guide rail 20. At the same time, each of the two clamping plates 51 is provided with a guide hole, and the two clamping plates 51 are respectively matched with the two ends of the guide rod 53 through the guide holes.

[0066] By providing the guide rod 53, it plays a supporting role and a guiding role for the movement of the clamping plate 51.

[0067] Preferably, the second driving member 52 includes a second screw rod 521 and a second motor 522. The clamping plate 51 has a threaded hole. The two ends of the second screw rod 521 are respectively matched with the threaded holes on the two clamping plates 51, such that the length direction of the second screw rod 521 is parallel to the length direction of the guide rod 53. At the same time, the second screw rod 521 is arranged above the guide rod 53.

[0068] Specifically, there are two second screw rods 521, which are respectively located above the two ends of the guide rod 53. One ends of the two second screw rods 521 are close to each other, and a bevel gear 523 is provided at this end. At the same time, a bevel gear 523 is also provided on the output shaft of the second motor 522. The bevel gears 523 on the two second screw rods 521 are meshed with the bevel gear 523 on the second motor 522, such that the second motor 522 can directly drive the two second screw rods 521 to rotate synchronously and in opposite directions, thereby realizing that the two clamping plates 51 move in opposite directions.

[0069] The above-described embodiments only represent the specific implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
