[0002] After the arc aluminum plate is produced, it is necessary to detect its radian to determine whether its bending radian meets the standard, which is convenient for subsequent assembly operations. However, the existing radian detection devices are only used to screen standard parts of the arc aluminum plate to determine a standard arc aluminum plate, and then compare the remaining aluminum plates with the standard parts, resulting in inaccurate detection results and inability to batch detect the arc aluminum plates, affecting the efficiency.

[0003] In view of the above problems, the present invention provides an arc aluminum plate radian detection device to solve the above problems. Summary of the Invention

[0004] To achieve the above object, the present invention provides the following technical solution: An arc aluminum plate radian detection device, comprising:

[0009] A downward pressing assembly, fixed on one side of the control panel.

[0010] Further, preferably, the downward pressing assembly includes:

[0019] The limiting components are configured to be multiple and are rotatably arranged in the detection box body and are located between multiple groups of the detection columns; and

[0020] The adjusting component is installed on one side of the detection box body away from the control panel.

[0021] Furthermore, preferably, the adjusting component includes:

[0022] The adjusting plate is fixed to the detection box body by a column;

[0023] The knob is threadedly connected to the adjusting plate and is limited by a nut; and

[0024] The adjusting column is rotatably arranged in the knob, and a torsion spring is arranged between the adjusting column and the knob.

[0025] Furthermore, preferably, the limiting component includes:

[0033] Compared with the prior art, the present invention provides an arc aluminum plate radian detection device, which has the following beneficial effects:

[0034] In the present invention, when it is necessary to determine the standard part of the arc-shaped aluminum plate, by rotating the knob, the limiting teeth are disengaged from the limiting rack, so that multiple detection columns can slide up and down freely. Then, according to the different displacement amounts of each detection column, the bending radian of the arc-shaped aluminum plate is determined. When it is necessary to perform batch detection on the arc-shaped aluminum plate, the limiting teeth and the limiting rack are used to form a limit. Then, the standard part is placed under the detection assembly and pressed down by the pressing cylinder, so that multiple detection columns expand and contract by different amounts according to the radian of the standard part. At this time, due to the limitation of the limiting teeth, the multiple detection columns cannot rebound. Then, the arc-shaped aluminum plate to be detected is placed on the conveyor belt for intermittent conveying. When it is conveyed under the detection assembly, the detection columns are brought into contact with the arc-shaped aluminum plate by the pressing cylinder, so as to determine whether the bending radian of the arc-shaped aluminum plate is qualified, greatly improving the detection efficiency and accuracy.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0040] Referring to Figures 1 to 4 , the present invention provides a technical solution: an arc-shaped aluminum plate radian detection device, including:

[0041] Base 1;

[0042] Conveyor belt 2, installed on the base 1;

[0043] Positioning blocks 3, configured to be multiple and arranged equidistantly on the conveyor belt 2 for positioning the arc-shaped aluminum plate;

[0044] A control panel 4, fixed to one side of the base 1; and

[0045] A pressing component 5, fixed to one side of the control panel 4.

[0046] It should be noted that the movement mode of the conveyor belt 2 is intermittent movement. The arc-shaped aluminum plate can be positioned by the positioning blocks 3, and the distance of each movement of the conveyor belt 2 is equal to the distance between the two positioning blocks 3. When detecting, the detection result can be displayed through the control panel 4, and when the detection is unqualified, a sound can also be emitted through the buzzer on the control panel 4, so as to distinguish qualified products and unqualified products.

[0047] In this embodiment, the pressing component 5 includes:

[0048] Support plates 51, configured to be two, fixed to the control panel 4;

[0049] A fixing plate 52, fixed between the two support plates 51;

[0050] A pressing cylinder body 53, fixed to the fixing plate 52;

[0051] A connecting plate 54, slidably arranged between the two support plates 51 and connected to the output end of the pressing cylinder body 53; and

[0052] A detection component 55, fixed to the lower end surface of the connecting plate 54.

[0053] As a preferred embodiment, the detection component 55 includes:

[0054] A detection box body 551, fixed to the lower end surface of the connecting plate 54;

[0055] Detection columns 552, configured to be multiple, equidistantly and slidably arranged on the lower end surface of the detection box body 51, and a return spring 553 is arranged between the detection columns 552 and the detection box body 551, and multiple groups of the detection columns 552 are arranged in a group along the width direction of the conveyor belt 2;

[0056] A limiting component, configured to be multiple, rotatably arranged in the detection box body 551 and located between multiple groups of the detection columns 552; and

[0057] An adjusting component, installed on one side of the detection box body 551 away from the control panel 4.

[0058] That is to say, by adjusting the limiting component through the adjusting component, the multiple detection columns 552 can be synchronously limited.

[0059] As a preferred embodiment, the adjusting assembly includes:

[0060] An adjusting plate 557, fixed to the detection box body 551 by a cylinder;

[0061] A knob 558, threadedly connected to the adjusting plate 557 and limited by a nut; and

[0062] An adjusting column 559, rotatably arranged in the knob 558, and a torsion spring is arranged between the adjusting column 559 and the knob 558.

[0063] That is to say, by rotating the knob 558, the adjusting column 559 can be driven to rotate, so as to adjust the limiting assembly.

[0064] As a preferred embodiment, the limiting assembly includes:

[0065] A plurality of rotating shafts 5526, rotatably arranged in the detection box body 551; and

[0066] A plurality of limiting teeth 5527, all fixed on the rotating shaft 5526 and corresponding to the detection column 552.

[0067] As a preferred embodiment, synchronous gears 555 are fixed to the mutually approaching ends of the adjusting column 559 and the rotating shaft 5526, and the plurality of synchronous gears 555 are driven by a synchronous chain 556.

[0068] As a preferred embodiment, the detection column 552 includes:

[0069] A column body 5521, slidably arranged in the detection box body 551, a contact inductor 5522 is fixed to the lower end surface thereof, and a detection section 5523 is fixed to the upper end surface;

[0070] An induction plate 5524, fixed to one side of the detection section 5523 and used in cooperation with the displacement inductor 554; and

[0071] A limiting rack 5525, fixed to the other side of the detection section 5523.

[0072] It should be noted that when the limit tooth 5527 limits the limit rack 5525, since it is a ratchet - type limit, it can prevent the detection column 552 from sliding down and resetting. Moreover, the tooth pitch of the limit rack 5525 is 2 mm. That is to say, when the limit tooth 5527 limits the limit rack 5525, the limit rack 5525 can also slide upward by no more than 2 mm, which means that the error in the arc detection of the arc - shaped aluminum plate is no more than 2 mm. When in use, first, the position of the detection column 552 is limited by a standard part. At this time, a batch of arc - shaped aluminum plates are detected. During the detection, multiple contact sensors 5522 are all in contact with the arc - shaped aluminum plate. However, when the displacement of one of the detection columns 552 reaches 2 mm (it should be noted that it cannot exceed 2 mm to avoid the detection column 552 reaching the next limit), and there are still contact sensors 5522 not in contact with the arc - shaped aluminum plate at this time, it indicates that the detection result is unqualified. That is to say, it avoids the need for the control panel 4 to calculate the results every time, which affects the efficiency. By only judging whether the contact sensor 5522 is in contact with the arc - shaped aluminum plate, the detection efficiency is greatly improved.

[0073] Specifically, when a standard part for the arc - shaped aluminum plate needs to be determined, by rotating the knob 558, the limit tooth 5527 is disengaged from the limit rack 5525, so that multiple detection columns 552 can freely slide up and down. Then, according to the different displacement amounts of each detection column 552, the bending arc of the arc - shaped aluminum plate is determined. When a batch of arc - shaped aluminum plates need to be detected, the limit tooth 5527 and the limit rack 5525 are made to form a limit. Then, the standard part is placed under the detection assembly 55, and the pressing cylinder 53 is used to press down, so that multiple detection columns 552 expand and contract by different amounts according to the arc of the standard part. At this time, due to the limit of the limit tooth 5527, multiple detection columns 552 cannot rebound. Then, the arc - shaped aluminum plate to be detected is placed on the conveyor belt 2 for intermittent transportation. When it is transported under the detection assembly 55, the detection column 552 is brought into contact with the arc - shaped aluminum plate through the pressing cylinder 53, so as to determine whether the bending arc of the arc - shaped aluminum plate is qualified, greatly improving the detection efficiency and accuracy.

[0074] The above - mentioned is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
