[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1:

[0039] An online detection device for steering knuckle shaft diameter, such as Figures 1-6 As shown, the system includes a base plate 1 and a placement plate 13. The placement plate 13 has an opening 14 inside, and an emergency stop component 9 is installed inside the opening 14. A digital display vernier caliper 2 is installed on the top of the base plate 1, and a display 3 is slidably mounted on the digital display vernier caliper 2. The digital display vernier caliper 2 is designed to facilitate the inspection of the steering knuckle shaft diameter. A detection plate 4 is installed on one side of the top of the display 3, and a fixing plate 5 is provided on one side of the top of the digital display vernier caliper 2. A side plate 6 is installed on one side of the top of the base plate 1, and the placement plate 13 is fixed on one side of the side plate 6. The placement plate 13 is designed to facilitate the placement of the steering knuckle, thereby facilitating the subsequent inspection of the steering knuckle shaft diameter.

[0040] Specifically, the emergency stop assembly 9 includes two slides 910 formed on the inner wall of the opening 14. A lead screw 911 is connected to the interior of one slide 910 via a bearing, and a slide block 909 is fitted onto the outer wall of the lead screw 911. A guide seat 912 is provided inside the other slide 910, and a positioning plate 908 is installed between the guide seat 912 and the slide block 909. A cavity 901 is formed inside the positioning plate 908, and a trigger switch 903 and a spring 902 are installed inside the cavity 901. One end of the spring 902 is connected to a pressing block 904, and the pressing block 904 has a threaded section extending through one side of the positioning plate 908. The threaded hole 905 has a threaded post 906 connected to its internal thread. A pad 907 is installed at one end of the threaded post 906. When the pad 907 contacts the detection plate 4, as the detection plate 4 continues to move, it will push the pad 907 to move and push the contact block 904 to move. The slide 909 is threadedly connected to the lead screw 911. One end of the lead screw 911 extends through to the outside of the placement plate 13 and is connected to a handle. The operator can rotate the lead screw 911 through the handle. After the lead screw 911 rotates, it will drive the slide 909 to move, and then drive the positioning plate 908 to move. The positioning plate 908 can support the steering knuckle.

[0041] Specifically, the trigger switch 903 is electrically connected to the electric push rod 11. When the trigger switch 903 is pressed, it will immediately shut off the electric push rod 11, thereby preventing the electric push rod 11 from working and avoiding excessive movement of the detection plate 4. The pressing block 904 is located on one side of the trigger switch 903 and is slidably connected to the cavity 901. When the pressing block 904 is subjected to force, it will slide into the cavity 901 and press the trigger switch 903. The top of the detection plate 4 and the top of the fixing plate 5 both pass through the through opening 14. The positioning plate 908 is slidably connected to the slide groove 910 through the guide seat 912 so that the positioning plate 908 can drive the guide seat 912 to move when it moves, thereby improving the stability of the positioning plate 908 when it moves.

[0042] See Figures 1-3 A mounting plate 12 is installed on one side of the bottom of the placement plate 13, and an electric push rod 11 is installed on one side of the mounting plate 12. The output end of the electric push rod 11 is connected to the detection plate 4 through a piston rod. When the steering knuckle shaft diameter needs to be detected, the electric push rod 11 can be activated to retract the piston rod, thereby moving the detection plate 4 so that the detection plate 4 fits against the inner wall of the steering knuckle shaft diameter. A control panel 7 is installed on the outer surface of the side plate 6, and the control panel 7 is electrically connected to the electric push rod 11, the digital vernier caliper 2, and the display 3 respectively, so that the electric push rod 11, the digital vernier caliper 2, and the display 3 can be started or stopped through the control panel 7.

[0043] Example 2:

[0044] Based on the above embodiment one, the following structure will be set to facilitate the positioning of the steering knuckle.

[0045] See Figures 1-2 The top of the side plate 6 is threaded with a threaded rod 8, and the bottom end of the threaded rod 8 is connected to a positioning rod 10. A turntable is installed at the top of the threaded rod 8. When the steering knuckle needs to be positioned, the operator can rotate the threaded rod 8 through the turntable, so that the threaded rod 8 moves down and drives the positioning rod 10 to move down. After the positioning rod 10 contacts the top side of the steering knuckle, the steering knuckle can be positioned.

[0046] The working principle of this utility model is as follows: First, the operator installs the device and connects the power supply. Then, the steering knuckle is placed on the placement plate 13, and the shaft hole of the steering knuckle is aligned with the through-hole 14, with one side of the inner side of the shaft hole of the steering knuckle fitting against the fixing plate 5. Next, the screw 911 is rotated, causing the slide 909 to move, which in turn moves the positioning plate 908, and then moves the pad 907, so that the pad 907 is positioned below the shaft hole. When the position of the pad 907 is such that the detection plate 4 moves to fit against the inner wall of the shaft hole of the steering knuckle, the pad 907 causes the contact block 904 to press the trigger switch 903. The operator first performs a test to adjust the position of the pad 907. In this way, the shaft holes of the same batch of steering knuckles can be tested. Then, the screw rod 8 is rotated by the turntable. This causes the threaded rod 8 to move down and drive the positioning rod 10 down. After the positioning rod 10 contacts the top side of the steering knuckle, the steering knuckle can be positioned. Then, the electric push rod 11 is activated, causing the piston rod to retract, which in turn drives the detection plate 4 to move towards the pad 907. The pad 907 will first contact the detection plate 4. As the detection plate 4 continues to move, it will push the pad 907 to move and push the contact block 904 to move. When the contact block 904 touches the trigger switch 903, the trigger switch 903 will immediately stop the electric push rod 11. At this time, one side of the detection plate 4 is in contact with the other side of the shaft hole of the steering knuckle, thereby preventing the detection plate 4 from moving excessively and causing damage. The operator can then check whether the shaft diameter of the steering knuckle shaft hole is qualified according to the digital display vernier caliper 2.

[0047] If the position of the pad 907 needs to be adjusted so that the detection plate 4 moves to fit against the inner wall of the shaft hole of the steering knuckle, the pad 907 will just drive the contact block 904 to press the trigger switch 903 and immediately close the electric push rod 11. The operator can adjust the position of the pad 907 by rotating the pad 907, which will cause the threaded column 906 to move in the threaded hole 905.
