[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1 to 5 This utility model provides a technical solution:

[0034] An inspection device for stamped sheet metal parts of automobiles includes a mounting plate 1. Adjusting rods 5 are rotatably mounted on both the left and right sides of the mounting plate 1. U-shaped rods 51 are threaded onto the circumferential surface of the adjusting rods 5. Sliding rods 52 are fixedly mounted on the inner sides of adjacent ends of the two U-shaped rods 51. A detection component 6 is slidably disposed between the two sliding rods 52. The detection component 6 includes a hollow rod 61 slidably mounted between the two sliding rods 52. Cross rods 64 are horizontally and evenly arranged inside the hollow rod 61. A first spring 65 is fixedly installed between the upper and lower ends of the horizontal part of the 64 and the inner wall of the cavity rod 61; a U-shaped slide rod 66 is slidably installed on the outer side of the cavity rod 61, a rectangular rod 67 is slidably installed at the front end of the U-shaped slide rod 66, a screw hole detection rod 68 is fixedly installed at the lower end of the rectangular rod 67, and a second spring 69 is fixedly installed between the upper end of the screw hole detection rod 68 and the lower part of the front end of the U-shaped slide rod 66; a sheet metal part 4 is provided above the mounting plate 1, and the lower end face of the cross rod 64 is in contact with the upper end face of the sheet metal part 4.

[0035] The cavity rod 61 has a cross groove 62 inside, and the cross rod 64 is slidably installed inside the cross groove 62. The upper and lower ends of the first spring 65, which are far apart, are fixedly installed on the upper and lower inner walls of the cross groove 62. The cavity rod 61 has U-shaped grooves 63 on both the front and rear sides, and the lower end of the U-shaped slide rod 66 is slidably installed inside the U-shaped groove 63 on both the front and rear sides.

[0036] By adopting the above technical solution, the operator first places the sheet metal part 4 on the upper end of the rotating head 35, starts the air pump 2, and the air pump 2 generates suction to firmly adsorb the sheet metal part 4 that is attached to the rotating head 35 through the pipe 21.

[0037] Depending on the situation on site, the operator rotates the adjusting rod 5. When the adjusting rod 5 rotates, the U-shaped rod 51 can rise or fall. Then, the slide rod 52 carries the cavity rod 61 in the detection assembly 6 to work synchronously. The cavity rod 61 carries the cross rod 64, the first spring 65 and the U-shaped slide rod 66 to fall synchronously until the upper end face of the cross rod 64 is tightly attached to the upper surface of the sheet metal part 4. At this time, the U-shaped slide rod 66 will carry the rectangular rod 67. The rectangular rod 67 carries the screw hole detection rod 68 and the second spring 69 to fall synchronously.

[0038] In use, the U-shaped slide bar 66 is slidable. Under the action of the U-shaped groove 63, the U-shaped slide bar 66 can move horizontally along the cavity bar 61. Under the action of the first spring 65, the protruding position of the sheet metal part 4 will cause the upper end of the cross bar 64 to slide out of the interior of the cross groove 62. The upper end face of the interior of the U-shaped slide bar 66 and the upper end face of the cross bar 64 are in a close fit. Once the cross bar 64 protrudes and obstructs the movement of the U-shaped slide bar 66, it can be known that the lower end of the protruding cross bar 64 is in an uneven state when it is in contact with the sheet metal part 4. Secondly, when the screw hole detection rod 68 is working, if the screw hole detection rod 68 passes through, it proves that the hole meets the requirements. If it does not pass through, there is an obstruction inside the surface hole.

[0039] During operation, the second spring 69 pushes the rectangular rod 67 downwards, and the rectangular rod 67 moves downwards synchronously with the screw hole detection rod 68. The lower end of the screw hole detection rod 68 then enters the interior of the hole. If it passes through the thick surface, the hole is opened well; if it does not pass through, the surface needs to be returned to the factory for processing. Therefore, with the cooperation of the above multiple structures, the flatness of the front and back surfaces of the sheet metal part 4 can be detected without local inspection, ensuring the overall inspection of the sheet metal part 4 and thus ensuring the good quality of the sheet metal part 4. Furthermore, the hole can be detected in real time during the flatness inspection process, saving the trouble of transferring it to the next worker for inspection.

[0040] Specifically, such as Figures 1 to 2 As shown, a vertical pole 11 is fixedly installed at the rear end of the mounting plate 1, a telescopic cylinder 12 is fixedly installed at the upper front end of the vertical pole 11, and a pressure plate 13 is fixedly installed on the lower telescopic rod of the telescopic cylinder 12.

[0041] An air pump 2 is fixedly installed on the lower end face of the mounting plate 1, and pipes 21 are fixedly installed on the circumferential surfaces of both the front and rear ends of the air pump 2; an adjustment assembly 3 is provided on the upper end face of the mounting plate 1, and the adjustment assembly 3 includes four hollow columns 32 fixedly installed on the upper end face of the mounting plate 1.

[0042] A driven gear 33 is rotatably mounted on the upper end of the hollow column 32. A threaded rod 34 is rotatably mounted from the upper end face of the driven gear 33 to the inside of the hollow column 32. A rotating head 35 is rotatably mounted on the upper end face of the threaded rod 34. The sheet metal part 4 is placed on the upper end of multiple rotating heads 35. The upper end of the pipe 21 and the lower end of the rotating head 35 are fixedly connected. A chain 36 is rotatably mounted on the circumferential surface of the driven gear 33. A motor 31 is fixedly mounted on the upper end face of the mounting plate 1. A driving gear 311 is fixedly mounted on the output shaft of the motor 31. The driving gear 311 meshes with the chain 36.

[0043] By adopting the above technical solution, the motor 31, which is fixedly installed on the upper surface of the mounting plate 1 in the adjustment assembly 3, is started. The output shaft of the motor 31 drives the drive gear 311 to rotate. The drive gear 311 drives the chain 36 to rotate. The chain 36 drives the driven gear 33 to rotate. When the driven gear 33 rotates, the threaded rod 34 can rotate inside the cavity column 32. When the threaded rod 34 rotates, it can move upward. The threaded rod 34 will drive the rotating head 35 to move synchronously. At this time, the rotating head 35 will move upward synchronously under the drive of the threaded rod 34. After reaching the specified height, the rotation of the motor 31 stops.

[0044] Place the sheet metal part 4 on the upper surface of the rotating head 35, start the air pump 2, and the air pump 2 will adsorb the sheet metal part 4 through the pipe 21. It should be noted that the length of the pipe 21 needs to be reserved according to the length of the threaded rod 34 to avoid the pipe 21 affecting the lifting and lowering of the threaded rod 34.

[0045] Then, a telescopic cylinder 12 is fixedly installed at the front end of the upright 11 for operation. The telescopic rod of the telescopic cylinder 12 pushes the pressure plate 13 downward to perform pressure testing on the sheet metal part 4. With the cooperation of the above-mentioned multiple structures, pressure testing can be performed on the sheet metal part 4 at different heights, thereby obtaining pressure test data of the sheet metal part 4 at different heights, so that the pressure testing of the sheet metal part 4 is no longer limited to the same height.

[0046] Working principle: Place the sheet metal part 4 on the upper surface of the rotating head 35 and start the air pump 2. The air pump 2 will adsorb the sheet metal part 4 through the pipe 21.

[0047] Rotate the adjusting rod 5, and the adjusting rod 5 will lower the U-shaped rod 51. The U-shaped rod 51 will lower the sliding rod 52, and the sliding rod 52 will lower the cavity rod 61. The lower end face of the cross rod 64 will fit against the upper surface of the sheet metal part 4.

[0048] Sliding the U-shaped slide bar 66, the protruding cross bar 64 will hinder the movement of the U-shaped slide bar 66, thus marking the protruding position. Manually pressing the protruding cross bar 64 will cause the lower first spring 65 to retract, and the U-shaped slide bar 66 will slide over to continue operation.

[0049] Then, the second spring 69 moves the rectangular rod 67 downwards, and the rectangular rod 67 moves the screw hole detection rod 68 downwards synchronously, so that the screw hole detection rod 68 enters the opened hole for detection.

[0050] In addition, the motor 31 is started, and the motor 31 drives the drive gear 311 to rotate. The drive gear 311 drives the chain 36 to rotate, and the chain 36 drives the driven gear 33 to rotate. The driven gear 33 causes the threaded rod 34 to rotate and move upward. The threaded rod 34 drives the rotating head 35 to move upward, place the sheet metal part 4, and start the air pump 2 to adsorb the sheet metal part 4.

[0051] Start the telescopic cylinder 12. The telescopic rod of the telescopic cylinder 12 moves the pressure plate 13 downward to perform a pressure test on the sheet metal part 4.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
