[0039] Figure 1 The three-dimensional structural schematic diagram after installing the door ring main body of the car door ring inspection hole flanging device according to an embodiment of the present disclosure is shown. Figure 2 The partial enlarged view at A of the car door ring inspection hole flanging device according to an embodiment of the present disclosure is shown. Figure 3 The three-dimensional structural schematic diagram of the car door ring inspection hole flanging device according to an embodiment of the present disclosure is shown. Please refer to Figure 1 , Figure 2 and Figure 3 , the car door ring inspection hole flanging device includes a base 1, and a support column 12 is arranged on the base 1 to contact the door ring main body 7. A first lever cylinder 2 is arranged on the base 1. The telescopic end of the first lever cylinder 2 is rotatably connected to a lever arm 21. One end of the support column 12 away from the base 1 is arranged within the rotation path of the lever arm 21. When the door ring main body 7 is arranged on the base 1, the door ring main body 7 is arranged between the support column 12 and the lever arm 21. The first lever cylinder 2 and the support column 12 cooperate to clamp the door ring main body 7 and fix the door ring main body 7 on the base 1. A detection mechanism 4, including a probe rod 42 arranged on the base 1. After the door ring main body 7 is arranged on the base 1, several probe rods 42 extend into the holes 71 of the door ring main body 7. Whether the probe rod 42 can extend into the hole 71 is used to judge whether the hole 71 is processed. A flanging mechanism 6, including a second lever cylinder 61 arranged on the base 1. The second lever cylinder 61 has the same structure as the first lever cylinder 2. The extension 72 of the door ring main body 7 is on the moving path of the lever arm 21 of the second lever cylinder 61. The lever arm 21 in the second lever cylinder 61 rotates and swings to push the bent extension 72 to a preset angle to form the door ring main body 7 by secondary processing. Through the settings of the base 1, the first lever cylinder 2, and the flanging mechanism 6, after clamping and fixing the door ring main body 7 once, the detection of the hole 71 processing of the door ring main body 7 and the secondary processing and forming of the door ring main body 7 can be carried out simultaneously. The detection and secondary processing and forming processes are combined and executed, reducing the simple waiting time and turnover links of the processes, directly compressing the overall production cycle, and improving production efficiency.

[0040] In some embodiments, the hole detecting rod 42 is a rod. However, in actual use, since the length of the hole detecting rod 42 is limited and the diameter of the hole 71 formed in the door ring main body 7 is relatively large, the hole detecting rod 42 can also be a block shape, and the present application does not limit the shape of the hole detecting rod 42.

[0041] Figure 4 Fig. shows a partial enlarged view at B of the car door ring hole detecting and flanging device according to an embodiment of the present disclosure. Figure 7 Fig. shows a three-dimensional structural schematic diagram of the flanging mechanism in the car door ring hole detecting and flanging device according to an embodiment of the present disclosure. Please refer to Figure 3 、 Figure 4 and Figure 7 The flanging mechanism 6 further includes a heating coil 63 and a main unit 631 connected to the heating coil 63. The main unit 631 includes a power supply and a controller. To ensure the safety performance of the car, the structural strength of the door ring main body 7 is relatively high, resulting in difficulty in bending the extension portion 72. The heating coil 63 can heat and soften the extension portion 72 to facilitate the flanging mechanism 6 to bend the extension portion 72 to a preset angle. The flanging mechanism 6 is connected to the base 1 through a slide rail and slider assembly 64. Before the double-lever cylinder bends the extension portion 72, first align the extension portion 72 and the heating coil 63, heat and soften the extension portion 72 through the heating coil 63, and then the flanging mechanism 6 slides and adjusts its position on the base 1 through the slide rail and slider structure to align the second lever cylinder 61 and the extension portion 72, so as to facilitate bending the extension portion 72 through the second lever cylinder 61.

[0042] Preferably, a second telescopic member 65 is further provided on the base 1. The telescopic end of the second telescopic member 65 is connected to the slide rail and slider assembly 64 to push the slider in the slide rail and slider assembly 64 to slide.

[0043] More preferably, an adjustment base 11 is provided on the base 1. A guiding surface 111 is provided on the adjustment base 11. The first lever cylinder 2, the detection mechanism 4 and the flanging mechanism 6 are arranged on the guiding surface 111. The set height and the angle of the guiding surface 111 on the adjustment base 11 are set according to the position of the door ring main body 7 on the base 1 to align the lever arm 21 of the first lever cylinder 2 with the support column 12, adjust the sensor 41 to a proper detection position, adjust the hole detecting rod 42 to correctly extend into the hole 71 and align the lever arm 21 of the second lever cylinder 61 with the extension portion 72.

[0044] In the above embodiments, the base 1 is provided with a split structure with the adjustment base 11 and the support column 12. In some other embodiments, the base 1 and the adjustment base 11 and the support column 12 can also be provided with an integral structure.

[0045] Figure 5 Fig. shows a partial enlarged view at C of the car door ring hole detecting and flanging device according to an embodiment of the present disclosure. Figure 6Shows a local enlarged view of the car door ring inspection hole flanging device according to an embodiment of the present disclosure, at D. Please refer to Figure 3 、 Figure 5 and Figure 6 , the detection mechanism 4 further includes a third telescopic member 43 and a second positioning block 44 provided on the base 1. The hole probing rod 42 is provided at the telescopic end of the third telescopic member 43. The second positioning block 44 is provided on the telescopic path of the third telescopic member 43. For example, the hole probing rod 42 that needs to extend into the hole 71 on the side of the door ring body 7 is first driven by the third telescopic member 43 to move away from the door ring body 7 before the door ring body 7 is fixed on the base 1. After the door ring body 7 is fixed on the base 1, the third telescopic member 43 then drives the hole probing rod 42 fixed on the third telescopic member 43 to move towards the door ring body 7 and extend into the hole 71. To avoid interference between the hole probing rod 42 and the door ring body 7.

[0046] In some embodiments, the detection mechanism 4 further includes a sensor 41 provided on the base 1. The sensor 41 is a distance sensor 41, and can be a commercially available ORD1M13 type optoelectronic distance sensor 41. When the hole 71 on the door ring body 7 is processed incorrectly, the hole probing rod 42 cannot extend into the hole 71 and interferes with the door ring body 7. At this time, the door ring body 7 is blocked by the hole probing rod 42 and cannot be placed in the preset position. The sensor 41 detects that the distance between it and the door ring body 7 is not within the error range, so as to automatically identify the processing error of the door ring body 7. Among them, in addition to being directly provided on the base 1, the sensor 41 can also be indirectly provided on the base 1 through structures such as a clamping base 51. And the sensor 41 can also be arranged parallel to the base 1, or can be arranged at an angle with the base 1 to better measure the distance between the sensor 41 and the door ring body 7.

[0047] Figure 8 Shows a schematic assembly structure diagram of the flanging block in the car door ring inspection hole flanging device according to an embodiment of the present disclosure. Please refer to Figure 3 、 Figure 7 and Figure 8. The first lever cylinder 2 also includes a connecting rod 22 and a lever base 23. One end of the connecting rod 22 is rotationally connected to the lever arm 21, and the other end of the connecting rod 22 is rotationally connected to the lever base 23. The lever base 23 is arranged on the first lever cylinder 2. When the first lever cylinder 2 is working, the telescopic end of the first lever cylinder 2 drives the lever arm 21 to move up and down. At this time, the connecting rod 22 limits the positional relationship between the lever arm 21 and the lever base 23, so that when the telescopic end of the first lever cylinder 2 is extended and retracted, the lever arm 21 swings around the lever base 23, and the swinging lever arm 21 moves away from the supporting column 12, or approaches the supporting column 12 and cooperates with the supporting column 12 to clamp the door knocker body 7. In addition, the structure of the second lever cylinder 61 is the same as that of the first lever cylinder 2. The working principle of the second lever cylinder 61 is also that the telescopic end of the second lever cylinder 61 is extended and retracted, driving its lever arm 21 to swing around the lever base 23, so that the lever arm 21 moves away from the extension part 72 or the lever arm 21 approaches and squeezes and bends the extension part 72 to a preset angle.

[0048] In some embodiments, an elastic pressing block 24 is provided on the lever arm 21 of the first lever cylinder 2. The lever arm 21 of the first lever cylinder 2 contacts the door knocker body 7 through the elastic pressing block 24. The elastic pressing block 24 can absorb the impact force generated in the process of pressing the door knocker body 7 through its own elastic deformation, so as to avoid the lever arm 21 rigidly contacting the door knocker body 7 and causing scratches or deformation of the door knocker body 7. At the same time, the elastic deformation characteristics of the elastic pressing block 24 itself can compensate for the position error between the lever arm 21 and the door knocker body 7, so as to ensure that the lever arm 21 stably supports the door knocker body 7.

[0049] In some embodiments, a flange block 62 is provided on the lever arm 21 of the second lever cylinder 61. An inclined surface 621 is provided on the flange block 62. After the extension portion 72 is bent, the inclined surface 621 fits the extension portion 72. Specifically, after the lever arm 21 of the second lever cylinder 61 swings around the lever base 23 to the end, the inclined surface 621 fits the surface of the extension portion 72. The inclined surface 621 is set to different inclination angles to push the bent extension portion 72 to different angles.

[0050] Figure 9 The figure shows a three-dimensional structural diagram of the clamping mechanism in the automobile door knocker inspection hole flanging device according to an embodiment of the present disclosure. Figure 3 , Figure 4 and Figure 9。The base 1 is further provided with a support mechanism 3. The support mechanism 3 includes a support block 31, a first telescopic member 32 provided on the base 1, and a first positioning block 33. The support block 31 contacts and supports the door ring body 7. The support block 31 is provided at the telescopic end of the first telescopic member 32. By the telescoping of the first telescopic member 32, the position of the support block 31 can be flexibly adjusted to stably support the position of the door ring body 7. In addition, the first positioning block 33 is provided on the telescopic path of the first telescopic member 32. The telescopic stroke of the telescopic rod on the first telescopic member 32 is limited by the first positioning block 33, and the support block 31 is quickly positioned to a preset support position to ensure that the support block 31 stably supports the door ring body 7. Among them, in addition to being directly provided on the base 1, the support mechanism 3 can also be directly provided on other components on the base 1 such as the clamping base 51 to be indirectly provided on the base 1.

[0051] In some embodiments, the base 1 is further provided with a clamping mechanism 5. The clamping mechanism 5 includes a clamping base 51, a clamping force arm 52 provided on the clamping base 51, and a clamping column 53. The reinforcing plate structure extending from the door ring body 7 passes through between the clamping base 51, the clamping force arm 52, and the clamping column 53 and is circumferentially clamped by the clamping base 51, the clamping force arm 52, and the clamping column 53. The circumferential clamping of the door ring body 7 effectively disperses the radial force generated during the bending process of the extension portion 72 and improves the stability of the fixation of the door ring body 7.

[0052] In some embodiments, clamping blocks 511 are respectively provided on the clamping base 51, the clamping force arm 52, and the clamping column 53 to contact the door ring body 7. The clamping blocks 511 are screwed to the clamping base 51, the clamping force arm 52, and the clamping column 53.

[0053] The first telescopic member 32, the second telescopic member 65, and the third telescopic member 43 in the vehicle door ring hole inspection and flanging device of the present application can be a motor-driven gear-rack structure, a motor-driven lead screw-nut mechanical transmission structure, a cylinder, or a hydraulic cylinder, which is convenient for realizing automatic control.

[0054] The specific working process of the present invention is as follows:

[0055] The feeding device places the door ring body 7 on the base 1. The support columns 12 and the support blocks 31 support the door ring body 7. The independently protruding part on the door ring body 7 passes through the gap between the clamping base 51, the clamping force arm 52 and the clamping column 53. At the same time, part of the hole detecting rod 42 extends into the hole 71 at the bottom of the door ring body 7. The telescopic end of the third telescopic member 43 extends out, driving the hole detecting rod 42 connected to the third telescopic member 43 to extend into the hole 71 on the side of the door ring body 7. At this time, the hole detecting rod 42 extends into all the holes 71 on the door ring body 7. Check the signal of the distance between the door ring body 7 and the sensor 41 output by the inspection sensor 41 to judge whether the distance between the door ring body 7 and the sensor 41 is within the error range. If the distance exceeds the error range, it is determined that the processing of the hole 71 of the door ring body 7 is unqualified. If the distance is within the error range, it is determined that the processing of the hole 71 of the door ring body 7 is qualified. Then the telescopic end of the first lever cylinder 2 extends out, driving the lever force arm 21 in the first lever cylinder 2 to swing around the lever base 23 until the lever force arm 21 cooperates with the support column 12 to clamp the door ring body 7. The main machine 631 energizes the heating coil 63 to raise the temperature of the heating coil 63, and the heating coil 63 heats the extension part 72. Then the flanging mechanism 6 slides and moves its position on the base 1 through the slide rail slider assembly 64 until the lever force arm 21 on the second lever cylinder 61 aligns with the extension part 72. The telescopic end of the second lever cylinder 61 extends out, driving the lever force arm 21 on the second lever cylinder 61 to swing around the lever base 23. While the lever force arm 21 swings, it squeezes the extension part 72 to a predetermined angle, completing the hole inspection and flanging of the door ring body 7. Finally, the telescopic ends of the first lever cylinder 2 and the second lever cylinder 61 contract, and the third telescopic member 43 contracts, driving the lever force arm 21 away from the door ring body 7 and pulling out the hole detecting rod 42 in the hole 71 on the side of the door ring body 7. At this time, the car door ring hole inspection and flanging device no longer restricts the upward movement of the door ring body 7, and the unloading device removes the door ring body 7 from the base 1.

[0056] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0057] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. 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. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
