[0027] like Figures 1 to 5As shown, the vehicle door panel sheet metal detection mechanism of the utility model includes: a test bench 1, on which a supporting portion 2 for placing and fixing a vehicle door 3 is formed, and the test bench 1 is provided with an extension groove 4 for separating the supporting portion 2 on the outer peripheral side of the supporting portion 2, and the extension groove 4 has a shape adapted to the side of the outer peripheral circle of the vehicle door 3; a limiting mechanism, which is arranged on the supporting portion 2 and is used to limit and fix the vehicle door 3 placed on the supporting portion 2; and a detection mechanism, which is arranged on the test bench 1, and when the vehicle door 3 is detected, the detection mechanism is lifted upward from the bottom of the supporting portion 2 through the extension groove 4 to contact the side of the outer peripheral circle of the vehicle door 3.

[0028] See also Figure 1 , Figure 4 Since the supporting part 2 on the test bench 1 is separated by the extending groove 4 , a support rod 5 needs to be arranged under the supporting part 2 to prop up the supporting part 2 .

[0029] See also Figure 1 , Figure 2 The extension groove 4 opened on the test bench 1 has a shape that is compatible with the outer circumference of the vehicle door 3. When the vehicle door 3 is placed on the supporting part 2 and fixed by the limiting mechanism, the circumference of the vehicle door 3 is located directly above the extension groove 4. At this time, by controlling the detection mechanism to rise, the detection element of the detection mechanism can extend through the extension groove 4 and contact with the side of the vehicle door 3, thereby realizing the detection when the size of the vehicle door 3 is smaller than the normal value. When the size of the vehicle door 3 is larger than the normal value, the part of the vehicle door 3 larger than the normal value will be located directly above the detection element, so that when the detection element rises, the vehicle door 3 will be lifted by the detection element, and then the detection when the size of the vehicle door 3 is larger than the normal value is realized; after the present application limits the position of the vehicle door 3 by the limiting mechanism, the detection mechanism is controlled to extend through the extension groove 4, thereby realizing the detection of whether the length of the vehicle door 3 meets the standard, thereby improving the detection efficiency of the present application for the vehicle door 3 and having practicality.

[0030] In one or more embodiments, the limiting mechanism includes a limiting cylinder 61 configured on the test bench 1, a first support plate 62 connected to the extended shaft end of the limiting cylinder 61, and at least two limiting columns 63 configured on the first support plate 62; wherein the limiting column 63 can pass through the supporting part 2 and enter the positioning hole of the vehicle door 3.

[0031] See also Figure 2 A through hole is vertically opened on the supporting part 2 corresponding to the positioning hole of the vehicle door 3, and a limiting column 63 passes through the through hole of the supporting part 2. There are at least two limiting columns 63. After at least two limiting columns 63 extend into the positioning hole of the vehicle door 3, the vehicle door 3 can be effectively prevented from shifting on the supporting part 2 of the test bench 1.

[0032] See also Figure 1 , Figure 4 , Figure 5When limiting the position of the vehicle door 3, the vehicle door 3 is first placed at a predetermined position of the supporting portion 2 so that the positioning hole of the vehicle door 3 corresponds to the through hole of the supporting portion 2. Then, the first support plate 62 and the limiting column 63 are controlled to be lifted by the limiting cylinder 61 so that the limiting column 63 extends out from the supporting portion 2 and passes through the positioning hole of the vehicle door 3, so as to limit and fix the vehicle door 3 in the horizontal direction. In this way, the position of the vehicle door 3 can be accurately limited and efficiently limited.

[0033] In one or more embodiments, the detection mechanism includes a lifting cylinder 71 arranged on the test bench 1, a second support plate 72 installed on the protruding shaft end of the lifting cylinder 71, and a contour piece 73 arranged on the top of the second support plate 72; wherein, the contour piece 73 has a structure adapted to the outer circumference of the vehicle door 3 on the surface of the side close to the supporting portion 2, and is provided with a detection component, which can contact the surface of the outer circumference of the vehicle door 3 after rising to a predetermined height to test the position data of the outer circumference of the vehicle door 3; the detection component at least includes a groove 74 opened on the contour piece 73 on the side facing the supporting portion 2, a pressure sensor 75 arranged in the groove 74, an elastic piece 76 arranged on the pressure sensor 75, and a contact head 77 connected to the elastic piece 76 and partially extending out of the groove 74.

[0034] See also Figures 1 to 5 When the vehicle door 3 is fixed by the limiting mechanism, the outer circumference of the vehicle door 3 is matched with the inner side surface of the profiling member 73, that is, when the lengths of various parts of the outer circumference of the vehicle door 3 are normal, after the profiling member 73 rises to be flush with the outer circumference of the vehicle door 3, the inner side surface of the profiling member 73 can contact with the outer circumference of the vehicle door 3.

[0035] See also Figures 1 to 5 When the length of the door 3 is too long, the profiling member 73 is driven to rise by the lifting cylinder 71, and the top of the profiling member 73 will abut against the part of the door 3 that is too long to achieve the detection purpose. When the length of the door 3 is too short, the profiling member 73 is driven to rise by the lifting cylinder 71 to be flush with the outer circumference of the door 3. At this time, under the action of the elastic member 76, the contact head 77 will abut against the surface of the door 3. When the length of the door 3 is too short, the pressure received by the pressure sensor 75 will be lower than the threshold, thereby achieving the detection purpose; through this setting, the outer circumference of the door 3 can be detected quickly and synchronously, while improving the detection accuracy of the door 3.

[0036] In one or more embodiments, the limiting mechanism further includes an air bag 64 disposed on the top of the limiting column 63, and the air bag 64 is connected to the air valve through a conduit.

[0037] See also Figure 1 , Figure 5The cross section of the airbag 64 is an inverted trapezoidal structure; when the limiting column 63 limits the vehicle door 3, air is supplied to the airbag 64 through the air valve to expand the airbag 64, thereby fixing the vehicle door 3 in the vertical direction; after the vehicle door 3 is inspected, the airbag 64 is exhausted through the air valve to make the outer diameter of the airbag 64 smaller than the diameter of the limiting column 63, thereby ensuring that the vehicle door 3 is smoothly separated from the limiting column 63 and improving the safety of the vehicle door 3 during the inspection process.

[0038] In one or more embodiments, the airbag 64 is made of rubber material, and an elastic metal wire is arranged in the airbag 64. By arranging the elastic metal wire in the airbag 64, the service life of the airbag 64 can be extended.

[0039] In one or more embodiments, the profiling member 73 is detachably disposed on the second support plate 72. The profiling member 73 is disposed on the second support plate 72 by bolts. When other models of vehicle doors 3 need to be tested, the profiling member 73 can be replaced, thereby improving the scope of application of the present application.

[0040] In one or more embodiments, the contact head 77 is a spherical structure. Figure 3 Through this configuration, the damage caused by the contact head 77 to the outer peripheral surface of the vehicle door 3 can be reduced.

[0041] In one or more embodiments, the elastic member 76 is a spring or elastic steel.

[0042] In addition, the utility model also provides a detection device, which has the door panel sheet metal detection mechanism in any of the above-mentioned embodiments.
