Detailed implementation manners

[0024] The following further elaborates on this application Figure 1-3 with reference to the accompanying drawings.

[0025] An embodiment of this application discloses a steel plate width measuring device.

[0026] Referring to Figure 1-3 , the steel plate width measuring device includes a workbench 2. The steel plate 1 is placed on the workbench 2. On both sides in the width direction of the steel plate 1, there are respectively arranged a first positioning plate 3 and a second positioning plate 4. The first positioning plate 3 and the second positioning plate 4 are respectively in contact with the two surfaces in the width direction of the steel strip. The first positioning plate 3 is fixedly arranged on the workbench 2, and the second positioning plate 4 is slidably arranged on the workbench 2 and slides in the direction of approaching or departing from the steel plate 1. There is a support frame 21 on the workbench 2. The support frame 21 is in a "冂" shape, and there is a drive assembly 5 on the support frame 21 for driving the second positioning plate 4 to slide.

[0027] The drive assembly 5 includes a drive motor 51, a lead screw 52, a drive block 53, and a limit rod 54. The drive motor 51 is fixed on the inner side wall of the support frame 21. The lead screw 52 is coaxially connected to the output shaft of the drive motor 51. The lead screw 52 passes through the drive block 53 and is threadedly connected to the drive block 53. The limit rod 54 passes through the drive block 53 and is slidably connected to the drive block 53. The limit rod 54 is arranged on both sides in the radial direction of the lead screw 52. There is a fixed plate 211 on the inner top wall of the support frame 21. One end of the limit rod 54 is fixedly connected to the inner side wall of the support frame 21, and the other end of the limit rod 54 is fixedly connected to the fixed plate 211. The limit rod 54 is used to limit the rotation of the drive block 53 along with the rotation of the lead screw 52.

[0028] There is a bearing seat 212 on the inner top wall of the support frame 21. The end of the lead screw 52 far from the drive motor 51 is rotationally connected to the support frame 21 through the bearing seat 212 to improve the rotational stability of the lead screw 52.

[0029] The drive block 53 is fixedly connected to the top surface of the second positioning plate 4 to drive the second positioning plate 4 to slide.

[0030] A laser distance sensor 31 is embedded in the first positioning plate 3 , and the laser distance sensor 31 is used to detect the distance between the first positioning plate 3 and the second positioning plate 4 . The driving assembly 5 is arranged above the laser distance sensor 31 to avoid obstructing the emission of laser pulses.

[0031] An intelligent display touch screen 6 is provided on the outer wall of the support frame 21 , and the intelligent display touch screen 6 is electrically connected to the laser ranging sensor 31 . The laser ranging sensor 31 sends distance information to the intelligent display touch screen 6 , and the intelligent display touch screen 6 is used to display the distance information.

[0032] A "start" button and a "stop" button are provided on the intelligent display touch screen 6. After clicking the "start" button, the laser distance sensor 31 starts and emits a laser to the second positioning plate 4. After clicking the "stop" button, the laser distance sensor 31 is turned off.

[0033] A contact sensor 41 is embedded in the second positioning plate 4. The contact surface of the contact sensor 41 and the steel plate 1 are flush with the contact surface of the second positioning plate 4 and the steel plate 1. When the contact sensor 41 contacts the surface of the steel plate 1, the drive motor 51 stops running and the second positioning plate 4 stops moving to avoid hitting the steel plate 1 and causing damage to the steel plate 1.

[0034] The bottom surface of the second positioning plate 4 is provided with a limit block 7, and the top surface of the workbench 2 is provided with a limit slot 71 for the limit block 7 to slide, thereby improving the sliding stability of the second positioning plate 4. Pulleys 8 are rotatably mounted on the bottom and both sides of the limit block 7, and the inner wall of the limit slot 71 is provided with a slide groove 81 for the pulley 8 to move, thereby converting sliding friction into rolling friction and improving the smoothness of the sliding of the second positioning plate 4.

[0035] The implementation principle of the device for measuring the width of a steel plate 1 in the embodiment of the present application is as follows:

[0036] Place the steel plate 1 on the workbench 2 and make one side of the steel plate 1 fit with the first positioning plate 3, start the drive motor 51 to move the second positioning plate 4 toward the steel plate 1, and when the contact sensor 41 contacts the surface of the steel plate 1, the drive motor 51 stops running and the second positioning plate 4 stops moving. The first positioning plate 3 and the second positioning plate 4 are respectively fitted with the two sides in the width direction of the steel strip, and then click the "Start" button to start the laser ranging sensor 31. The laser ranging sensor 31 starts and emits a laser to the second positioning plate 4. The laser pulse is scattered after contacting the second positioning plate 4, and part of the scattered light returns to the receiver of the laser ranging sensor 31. The time from the laser pulse being emitted to being received can be used to measure the distance between the first positioning plate 3 and the second positioning plate 4, that is, the width of the steel plate 1. This not only facilitates operation and improves measurement efficiency, but also improves measurement accuracy.

[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
