[0001] This utility model relates to the field of automotive fastener processing and testing technology, and more specifically, to a tensile testing device for automotive fastener processing. Background Technology

[0002] Automotive fasteners are various connecting parts used in automobile manufacturing and repair. Their function is to secure the various components and assemblies of a vehicle together. There are many types of fasteners, and a wide variety can be found. Quality control of fasteners is crucial, and tensile testing is required during the manufacturing process of automotive fasteners. Tensile testing equipment for automotive fasteners is used to test the performance of automotive fasteners (such as bolts, nuts, and pins) under tensile loads. This equipment is used in quality control and research and development to ensure that fasteners meet specific mechanical performance standards.

[0003] Traditional tensile testing devices for automotive fastener processing still have shortcomings: in the process of using traditional solutions, the clamping and fixing of automotive fasteners is cumbersome, labor-intensive, and inefficient.

[0004] Patent application CN202121805766.9 discloses a tensile testing device for automotive fastener processing, including a U-shaped frame. A through hole is provided on the top plate of the U-shaped frame. A first electric push rod is symmetrically mounted on the lower end of the top plate. A horizontal plate is connected to the bottom end of the first electric push rod. An insertion hole is provided in the middle of the horizontal plate. A second electric push rod is fixed to the upper end of the horizontal plate. A mounting plate is connected to the upper end of the second electric push rod. A rotating motor is mounted on the mounting plate. The output shaft of the rotating motor passes through the mounting plate and is connected to a rotating rod.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figures 1-4 In this utility model, a tensile testing device for automotive fastener processing includes a testing frame 1, a testing component 2 on the testing frame 1, a rotating frame 3 rotatably connected to the inner wall of the testing frame 1, uniformly distributed limiting seats 4 fixedly installed on the rotating frame 3, limiting components 5 inside the limiting seats 4, a drive motor 6 fixedly installed on the inner wall of the testing frame 1, the output shaft of the drive motor 6 being connected to the rotating frame 3 via bevel gear transmission, uniformly distributed ejection components 7 on the rotating frame 3, and a processor 8 installed inside the rotating frame 3. The testing component 2, drive motor 6, limiting components 5, and ejection components 7 are all signal-connected to the processor 8.

[0025] Test component 2 includes a hydraulic cylinder 201, which is mounted on the top of the test frame 1. An electric gripper 202 is fixedly mounted on the bottom of the hydraulic cylinder 201, and a force sensor 203 is connected to the hydraulic cylinder 201.

[0026] The limiting component 5 includes a mounting groove 501, which is opened inside the limiting seat 4. An electromagnetic ring 502 is fixedly installed on the inner wall of the mounting groove 501. A uniformly distributed limiting block 503 is slidably connected to the inner wall of the mounting groove 501. The limiting block 503 passes through the mounting groove 501 and extends into the interior of the limiting seat 4. A spring 504 is fixedly connected to the limiting block 503. The other end of the spring 504 is fixedly connected to the inner wall of the mounting groove 501.

[0027] The ejector assembly 7 includes a push rod 701, which is fixedly installed at the bottom of the rotary frame 3. The push rod 701 is located at the bottom of the limit seat 4, and a movable plate 702 is fixedly installed at the top of the push rod 701. The movable plate 702 is located inside the limit seat 4.

[0028] A display control panel 11 is installed on the right side of the testing frame 1, and the display control panel 11 is connected to the processor 8 via a signal.

[0029] The control panel 11 controls the parameters of each component, adjusting them according to the automotive fastener being tested. The values ​​of each component are displayed on the control panel 11 via the processor 8 for easy viewing. When a tensile test is required on the automotive fastener, the user places it into the top of the limiting seat 4. At this time, the movable plate 702 inside the ejector assembly 7 is in contact with the bottom of the limiting seat 4. As the automotive fastener is placed in, the current in the electromagnetic ring 502 decreases until it closes. At this point, the rebound force of the spring 504 is greater than the magnetic effect, and the spring 504 pushes multiple sets of limiting blocks 503 to move until they engage the automotive fastener. The drive motor 6 drives the bevel gear fixedly connected to it to rotate. The rotating frame 3, driven by the bevel gear, rotates 90 degrees clockwise and then stops. The user can then place the automotive fastener inside the limiting seat 4. The processor 8 controls the movement of the test assembly 2, and the hydraulic cylinder 201 drives the electric gripper 202 to move downwards to engage the top of the automotive fastener. The system first grasps and limits the movement of the fastener, then the hydraulic cylinder 201 pulls upward to apply force to the fastener. The force sensor 203 records the pulling force of the hydraulic cylinder 201 in real time and transmits it to the processor 8, which displays the result on the control panel 11. Once the hydraulic cylinder 201 reaches the set value, the pulling force is stopped. If the fastener breaks during this process, it is considered unqualified. After the test is completed, the test assembly 2 resets, and the drive motor 6 drives the rotating frame 3 to rotate, causing the tested fastener to rotate to the back. The processor 8 controls the operation of the ejection assembly 7 and the limiting assembly 5. The electromagnetic ring 502 generates magnetism to attract the metal block. The magnetism overcomes the force of the spring 504 and pulls the limiting block 503 back into the mounting slot 501. Then, the push rod 701 drives the movable plate 702 to move upward to eject the fastener, making it easier to remove. During the above process, the fastener that has rotated to the bottom of the test assembly 2 can be subjected to a tensile test simultaneously.

[0030] In this invention, multiple sets of limiting seats 4 are set on the rotating frame 3 to limit the automotive fasteners. With the help of the limiting component 5 and the ejection component 7, automatic limiting and ejection can be achieved, reducing the number of manual operation steps, improving the stability of the automotive fasteners, and improving the accuracy of subsequent fastener tensile testing. The rotating multiple sets of limiting seats 4 can simultaneously realize loading, unloading and testing, improving the efficiency of tensile testing of automotive fasteners.

[0031] Please see Figure 2 and 3 The top of the movable plate 702 is fixedly connected to a soft pad 9, and the soft pad 9 has evenly distributed anti-slip textures.

[0032] In this invention, after the car fastener is placed inside the limiting seat 4, the bottom end of the car fastener contacts the soft pad 9 with anti-slip texture, thereby enabling the car fastener to quickly maintain stability.

[0033] Please see Figure 1 and 4 Among them, a buzzer 10 is fixedly installed on the top of the detection frame 1, and the buzzer 10 is connected to the processor 8 via signal.

[0034] In this invention, when a car fastener breaks, the processor 8 receives a signal from the force sensor 203 and simultaneously controls the buzzer 10 to operate. The buzzer 10 emits a sound to alert the user so that subsequent operations can be performed in a timely manner.

[0035] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
