DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the scope of protection of the present utility model. Embodiment 1

[0026] A preferred embodiment of the automotive fastener tensile test device provided by the present utility model is as followsFigures 1 to 5 As shown in the figure: An automotive fastener tensile test device includes a workbench 1. At the top of the workbench 1, there is a tensile test equipment main body 2. Inside the inner wall of the tensile test equipment main body 2, two groups of sliding plates 3 are slidably connected. At the top of the sliding plates 3, a fixing mechanism 4 is fixedly connected. Inside the workbench 1, there is a storage cabinet 5. At the back of the workbench 1, there is a servo motor 6. The output end of the servo motor 6 is fixedly connected with a lead screw 7. The surface of the lead screw 7 is threadedly connected with a slider 8. At the top of the slider 8, a transmission column 9 is fixedly connected. The surface of the transmission column 9 is rotatably connected with a swing plate 10. At the top of the swing plate 10, a sliding column 11 is rotatably connected. At the top of the sliding column 11, a protective plate 12 is fixedly connected.

[0027] In this embodiment, a chute matching the slider 8 is opened at the top of the workbench 1. The slider 8 is embedded inside the chute at the top of the workbench 1 and is slidably connected with the workbench 1. Because the slider 8 is meshed with the lead screw 7, when the lead screw 7 rotates, it will drive the slider 8 to slide backward in the chute at the top of the workbench 1. At this time, the chute at the top of the workbench 1 will play a certain limiting role on the slider 8, enabling the slider 8 to slide horizontally.

[0028] In this embodiment, there are two groups of swing plates 10, and both groups of swing plates 10 are inclined. Because both groups of swing plates 10 are rotatably connected with the transmission column 9, and both groups of swing plates 10 are inclined, when the transmission column 9 moves, it will drive the two groups of swing plates 10 to swing relatively and move closer to each other.

[0029] In this embodiment, there are two groups of sliding columns 11. At the top of the workbench 1, two transverse grooves respectively matching the two groups of sliding columns 11 are opened. The two groups of sliding columns 11 respectively penetrate through the tops of the two groups of swing plates 10 and are embedded inside the two transverse grooves at the top of the workbench 1. Because the two groups of sliding columns 11 are respectively rotatably connected with the two groups of swing plates 10, and the two groups of sliding columns 11 respectively penetrate through the two groups of swing plates 10 and are embedded inside the two transverse grooves at the top of the workbench 1, when the two groups of swing plates 10 swing, it will drive the two groups of sliding columns 11 to slide relatively and move closer to each other inside the two transverse grooves at the top of the workbench 1. At this time, the two protective plates 12 fixedly connected with the two groups of sliding columns 11 will respectively slide relatively and move closer to each other along the top of the workbench 1. When the two protective plates 12 slide to contact each other and completely cover the working area, the protective effect can be achieved.

[0030] In this embodiment, there are two groups of protective plates 12, and both groups of protective plates 12 are transparent. Because both groups of protective plates 12 are transparent, it does not affect the staff to monitor the detection situation of automotive fasteners in real time. Embodiment 2

[0031] On the basis of Embodiment 1, a preferred embodiment of the automotive fastener tensile test device provided by the present utility model is as followsFigures 1 to 5 As shown: There are two sets of fixing mechanisms 4. The fixing mechanism 4 includes a mounting plate 41, a threaded rod 42, a transmission plate 43 and a locking plate 44. The top of the sliding plate 3 is fixedly connected to the mounting plate 41. The inner wall of the mounting plate 41 is rotatably connected to the threaded rod 42. The surface of the threaded rod 42 is threadedly connected to the transmission plate 43. The top of the transmission plate 43 is fixedly connected to the locking plate 44.

[0032] In this embodiment, two sets of threads in opposite directions are provided on the surface of the threaded rod 42. The two sets of threads on the surface of the threaded rod 42 are both engaged with the transmission plate 43. The top of the two sets of transmission plates 43 are both provided with locking plates 44. Because two sets of threads in opposite directions are provided on the surface of the threaded rod 42, and the two sets of transmission plates 43 are respectively engaged with it, when the threaded rod 42 rotates, it will drive the two sets of transmission plates 43 to slide relatively and approach each other. At this time, the two locking plates 44 fixedly connected to the two sets of transmission plates 43 will move relatively and approach each other accordingly. When the two locking plates 44 move to completely fit with the bottom end of the automotive fastener, the bottom end of the automotive fastener can be fixed.

[0033] In this embodiment, two sets of horizontally arranged transverse grooves are opened on the inner wall of the mounting plate 41. The two sets of transmission plates 43 are respectively embedded in the two sets of transverse grooves on the inner wall of the mounting plate 41 and are slidably connected to the mounting plate 41. Because two sets of horizontally arranged transverse grooves are opened on the inner wall of the mounting plate 41, and the two sets of transmission plates 43 are respectively embedded therein, when the transmission plate 43 slides, it will slide in the two sets of transverse grooves on the inner wall of the mounting plate 41. At this time, the two transverse grooves of the mounting plate 41 will play a certain limiting role on the two sets of transmission plates 43.

[0034] Working principle and usage process of the utility model: First, insert the bottom end of the automotive fastener into the interior of the mounting plate 41 of the lower fixing mechanism 4, and then manually rotate the threaded rod 42 clockwise. Since there are two groups of threads in opposite directions on the surface of the threaded rod 42, and the two groups of transmission plates 43 are respectively engaged with it, when the threaded rod 42 rotates, it will drive the two groups of transmission plates 43 to slide relatively and approach each other. At this time, the two locking plates 44 fixedly connected to the two groups of transmission plates 43 will move relatively and approach each other accordingly. When the two locking plates 44 move to completely fit with the bottom end of the automotive fastener, the bottom end of the automotive fastener can be fixed. Subsequently, drive the upper slide plate 3 and the fixing mechanism 4 to descend through the main body 2 of the tensile test equipment, so that the top end of the automotive fastener is embedded into the interior of the mounting plate 41 of the upper fixing mechanism 4, and then fix the top end of the automotive fastener through the same operation. After the fixing is completed, start the servo motor 6 to drive the lead screw 7 to rotate counterclockwise. Since the slider 8 is engaged with the lead screw 7, when the lead screw 7 rotates, it will drive the slider 8 to slide backward in the chute on the top of the workbench 1. At this time, the transmission column 9 fixedly connected to the slider 8 will move backward together. Since the two swing plates 10 are respectively rotatably connected to the transmission column 9, and the two swing plates 10 are inclined, when the transmission column 9 moves, it will drive the two swing plates 10 to swing relatively and approach each other. Since the two sliding columns 11 are respectively rotatably connected to the two swing plates 10, and the two sliding columns 11 respectively penetrate through the two swing plates 10 and are embedded into the two transverse grooves on the top of the workbench 1, when the two swing plates 10 swing, it will drive the two sliding columns 11 to slide relatively and approach each other respectively in the two transverse grooves on the top of the workbench 1. At this time, the two protective plates 12 fixedly connected to the two sliding columns 11 will slide relatively and approach each other along the top of the workbench 1 respectively. When the two protective plates 12 slide to contact each other and completely cover the working area, it can play a protective role, thereby preventing the automotive fastener from cracking and splashing during detection, and further ensuring the safety of the staff. Subsequently, the main body 2 of the tensile test equipment can be started to detect the automotive fastener. Since the two protective plates 12 are both transparent, it does not affect the staff to monitor the detection situation of the automotive fastener in real time.

[0035] The above is only the preferred embodiment of the utility model, and it is not intended to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
