[0038] refer to Figure 1-Figure 3 This embodiment provides an automobile parts strength testing device, comprising:

[0039] The feeding mechanism 1 includes a conveying assembly, and a plurality of placement grooves 111 of different widths are evenly opened on the outside of the conveying assembly. The placement grooves 111 are used to fix the nuts 3 before detection;

[0040] And a detection mechanism 2, which is set close to the end of the transmission component and is used to perform strength tensile testing on the nut 3.

[0041] Specifically, the transmission assembly includes a conveyor belt 11, two gears 14, a mounting frame 13 and a motor 15; wherein,

[0042] Each of the placement slots 111 is opened on the outer side of the conveyor belt 11; the inner side of the conveyor belt 11 is set to be tooth-shaped, and the inner side is meshed with two gears 14;

[0043] The shafts of the two gears 14 are each provided with a rotating shaft 12, and both ends of the rotating shaft 12 are connected to the mounting bracket 13;

[0044] The motor 15 is mounted on the mounting frame 13 , and an output end thereof is connected to one of the rotating shafts 12 .

[0045] In this embodiment, the present invention designs a feeding mechanism 1, which can use nuts 3 of different specifications by providing multiple placement slots 111 of different widths on the conveyor belt 11, eliminating the need for frequent replacement of fixtures, thereby improving detection efficiency.

[0046] Specifically, the detection mechanism 2 includes a detection box 21 and a limit assembly 22; wherein,

[0047] The detection box 21 is mounted above the conveying assembly. A feed port 210 is provided on a first side of the detection box 21, and a circular limiting groove 212 is provided on the inner side of the side. A circular sliding hole 211 is provided on a second side opposite to the first side of the detection box 21.

[0048] The limiting assembly 22 includes a mounting plate 221, a cylinder 1 222 and a limiting rod 223; the mounting plate 221 is horizontally mounted on the outer side of the second side portion of the detection box 21; the cylinder 1 222 is arranged on the mounting plate 221, and the output end of the cylinder 1 222 is connected to the connecting end of the limiting rod 223; the free end of the limiting rod 223 is movably connected to the circular sliding hole 211 and the circular limiting groove 212.

[0049] In this embodiment, the present invention designs the limiting assembly 22 to limit the bottom position of the nut 3, that is, during detection, the limiting assembly 22 keeps the nut 3 from shifting in the vertical direction before reaching the limit.

[0050] Furthermore, the detection mechanism 2 further includes an automatic stretching component 23, and the automatic stretching component 23 includes a hook 231, a slide 232 and a cylinder 233;

[0051] The cylinder 233 is vertically installed on the inner side of the top of the detection box 21, and its output end is connected to the slide 232;

[0052] The two ends of the slide plate 232 are slidably connected to the vertical slide grooves 213 opened on the inner side of the detection box 21;

[0053] The top of the hook 231 is connected to the slide plate 232 . The hook 231 is provided with an opening, and a photoelectric sensor is provided in the opening.

[0054] In order to achieve real-time detection, in this embodiment, a displacement sensor is also provided at the bottom of the skateboard 232, and the output end of the displacement sensor is transmitted to an external display device via an electrical signal; the present invention provides a displacement sensor at the bottom of the skateboard 232, which can monitor the tensile displacement of the nut 3 in real time and transmit the data to the external display device, so as to facilitate real-time recording and analysis of the detection results.

[0055] Furthermore, this embodiment of the present invention also includes a master controller 4, the input end of which is connected to the photoelectric sensor via an electrical signal, and the output end of which is connected to the cylinder 1 222 and the cylinder 233 via an electrical signal.

[0056] In order to improve the stability of the automatic stretching assembly 23 , in this embodiment, two vertical sliding grooves 213 are provided, which are respectively provided on the inner sides of the first side portion and the second side portion of the detection box 21 .

[0057] In order to facilitate the operator to observe the detection process in real time, in this embodiment, a transparent observation window 214 is further provided on the third side of the detection box 21; this design facilitates the operator to detect abnormal conditions in time and ensure the smooth progress of the detection.

[0058] In order to further improve the stability of the device, in this embodiment, the limiting assembly 22 further includes a reinforcing rod 224 , and both ends of the reinforcing rod 224 are respectively connected to the bottom of the mounting plate 221 and the side of the detection box 21 .

[0059] In this embodiment, the present invention designs a detection mechanism 2, which first limits the bottom position of the nut 3 through the limit component 22, and then according to the automatic stretching component 23, the main controller 4 receives the signal through the photoelectric sensor on the hook 231 to control the action of the cylinder 233. Because the nut 3 moves forward all the time, when the nut contacts the hook 231, the hook 231 only needs to apply a slight upward force to realize the automatic hooking of the nut 3, thereby realizing the automated control of the detection process, reducing manual intervention, and improving detection efficiency and safety.

[0060] It should be noted that the structural components involved in the detection mechanism 2 are all made of high-strength materials.

[0061] Working principle: Preferably, when in use, first place the nut 3 to be tested in the appropriate placement slot 111 according to its specifications and then start the motor 15. At this time, the main controller 4 controls the cylinder 233 to open and move its piston rod downward to a certain height and then close the cylinder 233; when the nut 3 is transported to the detection box 21, the main controller 4 starts cylinder 1 222 to move its piston rod outward until it reaches the circular limit groove 212 and gets stuck, and then closes cylinder 1 222; at this time, the nut 3 continues to be transported forward, and when the nut 3 is transported to contact with the hook 231, the photoelectric sensor on the hook 231 transmits its signal to the main controller 4, and the main controller 4 starts the cylinder 233 again to slowly retract its piston rod. At this time, the upper end of the nut 3 is also fixed by the hook 231 until the nut 3 reaches the limit value and is damaged or broken. At this time, the displacement sensor synchronously transmits the detected data to the external display device for background personnel to monitor and organize.

[0062] In summary, the automobile parts strength testing equipment of the present invention effectively solves the problems of traditional testing methods such as over-reliance on manual labor, poor fixture adaptability, and low testing efficiency through reasonable structural design and automated control. It has the advantages of high efficiency, high precision, easy operation, high cost-effectiveness and high safety, and is of great significance for improving the inspection quality and production efficiency of automobile parts.

[0063] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
