Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a pedal impact testing device. Background Technology

[0002] In the automotive parts industry, pendulum impact testing of pedals is crucial for assessing their quality and reliability. However, traditional pedal pendulum impact testing equipment still has several drawbacks: Firstly, the testing operation relies heavily on manual labor, such as manually lifting and releasing the pendulum. This not only leads to low efficiency but also makes it difficult to standardize the starting conditions of the pendulum for each test, thus affecting the accuracy and repeatability of the results. Secondly, traditional pedal pendulum impact testing equipment is not applicable to different models of pedal products, resulting in time-consuming and labor-intensive tooling adjustments when changing to different models, significantly increasing testing costs. Furthermore, traditional pedal pendulum impact testing also poses safety risks. During the manual lifting and releasing of the pendulum, improper operation could cause it to fall unexpectedly, resulting in serious injury to the operator. Utility Model Content

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "back", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane".

[0021] like Figure 1 As shown, a preferred embodiment of a pedal impact testing apparatus is illustrated, comprising:

[0022] Rack 1;

[0023] Quick-change fixture 2 is located at one end of the frame 1;

[0024] The pendulum impact column body fixture 3 is located in the middle of the frame 1.

[0025] A magnetic table welding frame 4 is placed at the other end of the frame 1. An electromagnetic suction table 6 is provided on the magnetic table welding frame 4. The electromagnetic suction table 6 is connected to the pendulum impact column body tooling 3.

[0026] Rotating device 5 is disposed between the magnetic table welding frame 4 and the pendulum impact column body fixture 3 and is connected to the pendulum impact column body fixture 3.

[0027] Furthermore, as a preferred embodiment, the quick-change tooling 2 includes: a tooling plate 21, a connecting plate 22, and a base 23. The base 23 is disposed at one end of the frame 1, and the connecting plate 22 is disposed on both sides of the tooling plate 21.

[0028] Furthermore, as a preferred embodiment, the tooling plate 21 has several threaded holes for bolt connection with different products.

[0029] Furthermore, as a preferred embodiment, the base 23 has several positioning holes 231 on both sides, and the connecting plate 22 has at least two fixing holes that cooperate with the positioning holes 231.

[0030] Furthermore, in a preferred embodiment, a positioning pin 24 is provided in the fixing hole and the positioning hole 231, and the connecting plate 22 is connected to the base 23 through the positioning pin 24. Furthermore, by rotating the connecting plate 22, the angle between the tooling plate 21 and the base 23 can be adjusted. After adjustment, the positioning pin 24 can be provided in the fixing hole and the positioning hole 231, and the connecting plate 22 is connected to the base 23 through the positioning pin 24, thereby keeping the angle between the tooling plate 21 and the base 23 fixed.

[0031] Furthermore, as a preferred embodiment, the pendulum impact column body fixture 3 includes: a mounting frame 31 and a pendulum 32. The mounting frame 31 is located in the middle of the frame 1. The upper end of the pendulum 32 is rotatably connected to the mounting frame 31. The rotating device 5 is operably in contact with the pendulum 32. The electromagnetic suction table 6 is operably connected to the pendulum 32.

[0032] Furthermore, in a preferred embodiment, the rotating device 5 includes a motor 51 and a rotating arm 52. The motor 51 is positioned between the magnetic table welding frame 4 and the pendulum impact column body fixture 3 and is connected to the frame 1. One end of the rotating arm 52 is connected to the output end of the motor 51, and the other end of the rotating arm 52 contacts the pendulum 32. Furthermore, the motor 51 can drive the rotating arm 52 to rotate, and the rotation of the rotating arm 52 can cause the pendulum 32 to rotate upwards.

[0033] Furthermore, in a preferred embodiment, both the motor 51 and the electromagnetic chuck 6 are connected to an external control system. More specifically, the control system is preferably configured as a PLC controller.

[0034] Furthermore, as a preferred embodiment, it also includes: a motor rotation arm laser sensor 53, which is disposed between the mounting bracket 31 and the motor 51, and close to the rotating arm 52. The motor rotation arm laser sensor 53 is connected to the PLC controller. Further, the motor rotation arm laser sensor 53 is used to monitor the rotation angle and position of the rotating arm 52. The motor rotation arm laser sensor 53 can send the detected information to the PLC controller, which then controls the rotation of the motor 51 according to the received signal. When the pendulum 32 needs to move upward, the PLC controller controls the motor 51 to drive the rotating arm 52 to rotate upward, thereby causing the pendulum 32 to rotate. After the rotating arm 52 rotates upward at a certain angle, the PLC controller controls the motor 51 to drive the rotating arm 52 to rotate downward, so that the rotating arm 52 can move away from the pendulum 32, and after rotating downward, the rotating arm 52 will no longer contact the pendulum 32, thereby preventing the pendulum 32 from being interfered with by the rotating arm 52 during its descent.

[0035] Furthermore, as a preferred embodiment, it also includes a pendulum laser sensor 61, which is disposed on the outer wall of the electromagnetic chuck 6. The pendulum laser sensor 61 is further used to detect the swing height and position of the pendulum 32 during its movement.

[0036] Furthermore, as a preferred embodiment, the upper end of the pendulum 32 is rotatably connected to the upper end of the mounting bracket 31 via a connecting rod.

[0037] The basic principle of this utility model is as follows: In use, the product to be tested is connected to the tooling plate 21, and the angle between the tooling plate 21 and the base 23 is adjusted. After the adjustment is completed, the motor 51 is started, which drives the rotating arm 52 to rotate. The rotation of the rotating arm 52 will drive the pendulum 32 to move towards the electromagnetic suction table 6. Then, the PLC controller controls the electromagnetic suction table 6 to attract the pendulum 32. Then, the rotating arm 52 rotates in the opposite direction under the drive of the motor 51 and quickly moves away from the pendulum 32. After a certain period of time, the PLC controller controls the electromagnetic suction table 6 to release the pendulum 32. The pendulum 32 will move downward under its own gravity and impact the product on the tooling plate 21. After the impact ends, the swing of the pendulum 32 will gradually become smoother during the energy decay process. Finally, the pendulum 32 will stop in the middle position of the mounting frame 31 and be in a natural hanging state.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
