[0030] like Figure 1-4 As shown, this utility model provides a metal product surface flatness detection device, which has a base plate 1, and two longitudinally arranged upright plates 41 are fixedly installed on the right side of the base plate 1. A detection component 4 is provided between the two upright plates 41 in a longitudinal sliding connection.

[0031] The base plate 1 is fixedly installed with a testing platform 11, the top left wall of the base plate 1 is fixedly installed with a gantry frame 2, the right wall of the gantry frame 2 is vertically slidably connected with a flipping component 20, and the top wall of the gantry frame 2 is provided with a lifting component 30 for driving the flipping component 20 to move.

[0033] Optionally, in the above technical solution, a counterweight 27 is vertically slidably connected to the left wall of the gantry 2, and one end of a chain 28 is fixedly installed on the top wall of the counterweight 27.

[0034] Optionally, in the above technical solution, the lifting assembly 30 includes two bearing seats 31 symmetrically fixedly installed on the top wall of the gantry frame 2, and one end of the rotating rod 32 is rotatably connected to each bearing seat 31 through a bearing.

[0035] Each end of the rotating rod 32 near the bearing seat 31 is fixedly equipped with a sprocket 33 coaxially arranged with it, and the sprocket 33 is connected to the chain 28 for transmission.

[0036] Optionally, in the above technical solution, a guide rod 42 and a rotatably connected screw 43 are fixedly installed between the upright plates 41, and the detection component 4 includes a movable plate 44, one side of the movable plate 44 is slidably connected to the guide rod 42, and the other side of the movable plate 44 is threadedly connected to the screw 43.

[0037] Optionally, in the above technical solution, a telescopic cylinder 45 is fixedly installed on the top wall of the middle part of the movable plate 44, and the movable end of the telescopic cylinder 45 passes through the movable plate 44 downward and a connecting plate 51 is fixedly installed at the end.

[0038] Optionally, in the above technical solution, two T-shaped rods 52 are slidably connected to the top wall of the connecting plate 51. The bottom ends of the T-shaped rods 52 are fixedly connected to a connecting frame 53 with an inverted "U" shape. A roller 54 is rotatably connected inside the connecting frame 53. A distance sensor 55 is fixedly installed on the top wall of the connecting frame 53.

[0039] Furthermore, the sliding connection method of this application includes two sets of slide rails 25 and sliders 26. The slide rails 25 are fixedly installed on the left and right walls of the gantry frame 2, and the sliders 26 are fixedly installed on the right wall of the counterweight block 27 and the left wall of the support plate 21, respectively. The sliders 26 are slidably connected to the corresponding slide rails 25 on the same side, providing guidance for the vertical sliding connection.

[0040] Furthermore, a dual-head motor 34 is fixedly installed in the middle of the top wall of the gantry 2. The output shaft of the dual-head motor 34 is connected to the end of the rotating rod 32 that is close to each other through a coupling. A servo motor 29 is fixedly installed in the middle of the left wall of the support plate 21. The output shaft of the servo motor 29 extends to the right, passes through the support plate 21, and is connected to the middle of the turntable 22. A drive motor 46 is fixedly installed on the outer wall of a vertical plate 41. The drive motor 46 passes through the vertical plate 41 and is connected to the screw 43 through a coupling.

[0041] The servo motor 29, dual-head motor 34, and drive motor 46 are all capable of rotating clockwise and counterclockwise. The clamping plate 24 is always positioned below the roller 54. (Initially, the bottom walls of the clamping plate 24 and support plate 21 are flush). The device performs a detection after the clamping plate 24 rises. The detection platform 11 assists in the turning process, preventing interference with the flipping of the clamping plate 24.

[0042] Working principle:

[0043] In its initial state, the clamp 24 is as follows Figure 1 As shown, the metal product to be tested is positioned between two clamps 24, perpendicular to the ground.

[0044] Start the double-headed cylinder 23 to retract its two movable ends simultaneously until the clamping plate 24 clamps the metal product in the middle, and the telescopic cylinder 45 drives the connecting plate 51 to move down until the roller 54 abuts against the metal product. The detection component 4 then detects the side of the product that is at the top at this time.

[0045] After one side is inspected, the movable end of the telescopic cylinder 45 is fully retracted, so that the roller 54 is at the highest position. At this time, the flipping component 20 rotates 90° clockwise and moves down until the metal part (more than half of the whole) abuts against the inspection table 11. At this time, the clamping plate 24 moves outward and releases the clamping of the metal part.

[0046] Then rotate counterclockwise 90° back to the initial angle, so that the clamping plate 24 clamps the metal product again. After clamping, it moves up to the initial height. In this way, the metal product is in the position of the top surface and has completed one flip. It is detected by the detection component 4. If it is necessary to flip it again to check the next side, the operation is repeated.

[0047] The lifting (i.e. height adjustment) method of the flipping component 20 is as follows: start the dual-head motor 34 to make its output shaft rotate clockwise at the same time, and drive the sprocket 33 to rotate through the connection with the rotating rod 32, thereby causing the sprocket 33 to move to the right and drive the support plate 21 to move down (rotating counterclockwise will cause the support plate 21 to move up).

[0048] The flipping mechanism of the flipping component 20 is as follows: the first flip is driven by the servo motor to rotate the turntable 22 90 degrees clockwise, and the next flip is driven by the servo motor to rotate the turntable 22 90 degrees counterclockwise to reset, and so on, alternating between clockwise and counterclockwise to generate 90° rotation.

[0049] The detection method of the detection component 4 is the same as that in the prior art. Specifically, the telescopic cylinder 45 is activated to drive the moving plate 44, etc., so that the roller 54 moves downward until it contacts the metal product. The rotation of the drive motor 46 drives the screw 43 to rotate, so that the moving plate 44 moves forward or backward along the guide rod 42. If it moves to an uneven part of the surface of the metal product, the roller 54 will drive the connecting frame 53 and the distance sensor 55 to move upward. The distance sensor 55 detects that the distance between the connecting frame 53 and the connecting plate 51 has changed, that is, the surface of the metal product is uneven.

[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
