[0027] As a further implementation of this solution, the inside of the chord frame 21 is hollow. Limited-sliding tracks are provided at the left and right ends of the chord frame 21. The top of the chord frame 21 is fixedly connected to one side of the upper end of the detection device support 1. The inner-thread slider 24 is in the shape of a rectangular body. A threaded hole is provided inside the inner-thread slider 24. Limited-sliding blocks are fixedly connected to the left and right sides of the inner-thread slider 24. The inner-thread slider 24 is slidably connected to the inside of the chord frame 21 through the limited-sliding blocks. A straight hole is provided inside the inner-thread slider 24. The limited-sliding post 27 is in the shape of a cylinder. The limited-sliding post 27 is installed inside the straight hole. The top of the push plate 26 is in contact with one side of the upper end of the impact post 33, facilitating the upward movement of the impact post 33 and the impact hammer 34, so that there is a certain amount of movement space when the impact post 33 and the impact hammer 34 move downward, achieving the effect of limiting the movement of the inner-thread slider 24 and improving the convenience of use;
[0028] As a further implementation of this solution, the middle part of the movable groove 32 is in the shape of a cylinder, and the front and rear parts of the movable groove 32 are in the shape of rectangular bodies. The movable groove 32 runs through the front and rear ends of the impact housing 31. The top of the impact housing 31 is fixedly connected to one side of the upper end of the detection device support 1. A limited-sliding plate is installed at the top of the impact post 33. A rectangular plate is installed at the rear end of the limited-sliding block of the impact post 33. The spring 35 is inside the impact housing 31. The double-shaped block 36 is composed of a cylinder and a rectangular body. The front end of the double-shaped block 36 is fixedly connected to the rear end of the connection chassis 43. At this time, under the elastic force of the spring 35, the impact post 33 and the impact hammer 34 are pushed, and the impact hammer 34 impacts the casting housing of the track traction motor, achieving the effect of performing an impact resistance test on the casting housing of the track traction motor;
[0029] As a further implementation of this solution, a limited-sliding plate is installed on one side of the connection chassis 43 close to the track groove 42. Limited-sliding bars are installed at the front and rear ends of the limited-sliding plate of the connection chassis 43. The top of the limited-support plate 41 is fixedly connected to one side of the lower end of the detection device support 1. The outside of the gear 45 meshes with the outside of the rack 46, and the applied impact force can be adjusted according to different models and materials, improving the practicability of the device and enabling it to meet diverse test requirements.
[0030] Workflow: When the device is in use, it is powered on by an external power supply. When adjusting the applied impact force according to different models and materials, the electric telescopic rod 25 is started. The electric telescopic rod 25 pushes the push plate 26 to move. The movement of the push plate 26 drives the limit sliding column 27 to move. The limit sliding column 27 is slidably connected to the inner side of the internal thread slider 24 to improve the stability of the push plate 26 during movement. At this time, the top of the push plate 26 is in contact with one side of the upper end of the impact column 33. The first servo motor 22 is started. The first servo motor 22 drives the threaded rod 23 to rotate. The threaded rod 23 drives the internally threaded slider 24 spirally connected to the outside to move upward. The internally threaded slider 24 is slidably connected to the inner side of the chord frame 21, which plays a role in limiting the movement of the internally threaded slider 24. The movement of the internally threaded slider 24 drives the push plate 26 to move upward through the limit sliding column 27 and the electric telescopic rod 25. The push plate 26 pushes the impact column 33 to move upward. The impact column 33 drives the impact hammer 34 to move upward. At this time, there is a distance between the top of the impact column 33 and the lower end of the movable groove 32, which is convenient for the impact column 33 to drive the impact hammer 34 to move. Then, the second servo motor 44 is started. The second servo motor 44 drives the gear 45 to rotate. The outside of the gear 45 meshes with the outside of the rack 46. At this time, while the gear 45 rotates, it also moves downward. The connection chassis 43 is driven by the second servo motor 44 to move. The connection chassis 43 is slidably connected to the rail groove 42 provided at the beginning of the limit support plate 41, which plays a role in limiting the movement of the connection chassis 43. The connection chassis 43 drives the double-shaped block 36 fixedly connected to the rear end to move downward. When the double-shaped block 36 moves downward, it impacts the casting housing of the track traction motor, and the spring 35 is compressed. The spring 35 undergoes elastic contraction at this time. According to Hooke's law, the longer the length of the spring 35 is compressed, the greater the elastic force of the spring 35 is at this time. According to the need, control the moving distance of the connection chassis 43. After the adjustment is completed, the electric telescopic rod 25 is started at this time to make the push plate 26 away from the top of the impact column 33. At this time, under the elastic force of the spring 35, the impact column 33 and the impact hammer 34 are pushed, and the impact hammer 34 impacts the casting housing of the track traction motor, achieving the effect of anti-impact detection on the casting housing of the track traction motor.
