DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] The embodiment of the present application discloses an intelligent laser marking instrument rear-end collision base.

[0030] Reference Figure 1-3 The intelligent laser marking instrument rear-end base includes a fixed plate 1 and a rotating table 2. The end faces of the fixed plate 1 and the rotating table 2 are both circular. The rotating table 2 is rotatably arranged on the fixed plate 1. The laser marking instrument is fixed on the rotating table 2 through a connecting piece. The fixed plate 1 is provided with a driving component 4 for driving the rotating table 2 to rotate.

[0031] The driving assembly 4 includes a driving motor 41, a driving worm 42, and a driving worm wheel 43. The driving motor 41 is a reduction motor. The driving motor 41 is fixed on the fixed plate 1. The output shaft of the driving motor 41 is coaxially connected with the driving worm 42. The driving worm 42 is meshed with the driving worm wheel 43. The driving worm wheel 43 drives the rotating table 2 to rotate through auxiliary parts.

[0032] A silicon optical sensor for detecting laser light is provided in the laser receiver, and the silicon optical sensor is electrically connected to the drive motor 41. After the silicon optical sensor sends the laser signal to the control system of the drive motor 41, the control system controls the output shaft of the drive motor 41 to rotate, so that the drive motor 41 drives the laser marking instrument to rotate until the landing point of the laser light falls on the specified position. In this embodiment, the silicon optical sensor includes two silicon photocells arranged at intervals. The drive motor 41 first drives the rotating table 2 to rotate rapidly. When the laser of the laser marking instrument moves to contact the silicon photocell, the drive motor 41 drives the rotating table 2 to rotate slowly until the laser landing point of the laser marking instrument falls in the middle of the two silicon photocells, which is the final position, thereby improving the positioning accuracy of the landing point.

[0033] The end of the driving worm wheel 43 close to the fixing plate 1 is coaxially connected with a mounting ring 431, and the mounting ring 431 is integrally formed with the driving worm wheel 43. A mounting hole 11 for the mounting ring 431 to penetrate is provided in the center of the fixing plate 1, and the outer peripheral wall of the mounting ring 431 is in contact with the inner peripheral wall of the mounting hole 11. The outer diameter of the driving worm wheel 43 is larger than the outer diameter of the mounting ring 431.

[0034] An annular step 12 for placing the driving worm gear 43 is coaxially fixedly connected to the top surface of the fixing plate 1 . The inner circumferential wall of the annular step 12 is flush with the inner circumferential wall of the mounting hole 11 , and the driving worm gear 43 is mounted on the annular step 12 .

[0035] A positioning ring groove 4311 is formed on the outer peripheral wall of the mounting ring 431 . A positioning spring 4312 is clamped in the positioning ring groove 4311 . A surface of the positioning spring 4312 close to the driving worm gear 43 abuts against the bottom surface of the fixing plate 1 .

[0036] The connecting member is a connecting bolt 3, the screw of which coaxially passes through the mounting ring 431, the driving worm gear 43, and the rotating table 2. The outer diameter of the screw of the connecting bolt 3 is smaller than the inner diameter of the mounting ring 431, so that the connecting bolt 3 does not directly contact the mounting ring 431. The screw of the connecting bolt 3 passes through the driving worm gear 43 and is threadedly connected to the rotating table 2. The part of the screw of the connecting bolt 3 that passes through the rotating table 2 is threadedly connected to the bottom end of the laser marking instrument.

[0037] The auxiliary part is an auxiliary ring plate 5, which is threadedly connected to the connecting bolt 3. The auxiliary ring plate 5 is located at the end of the mounting ring 431 away from the rotating table 2. The side of the rotating table 2 close to the auxiliary ring plate 5 is pressed against the side of the driving worm gear 43 away from the auxiliary ring plate 5, and the side of the auxiliary ring plate 5 close to the mounting ring 431 is pressed against the side of the mounting ring 431 away from the rotating table 2. A limit ring 51 is coaxially connected to the side of the auxiliary ring plate 5 close to the mounting ring 431. The limit ring 51 is located outside the mounting ring 431. The inner circumferential wall of the limit ring 51 is in contact with the outer circumferential wall of the mounting ring 431, which provides circumferential protection for the driving worm gear 43.

[0038] The rotating table 2 and the auxiliary parts are both made of plastic. By setting the plastic parts at both ends of the driving worm gear 43, the rotating table 2 and the auxiliary ring plate 5 are worn when the driving worm gear 43 rotates, reducing the wear of the driving worm gear 43, and reducing the possibility of the driving worm gear 43 and the rotating table 2 getting stuck, and the driving worm gear 43 and the auxiliary ring plate 5 getting stuck. The rotating boss and the auxiliary ring plate 5 can be threadedly connected with the connecting bolts 3. The rotating table 2 and the auxiliary ring plate 5 can be easily replaced after being damaged. The loss of replacing the rotating table 2 and the auxiliary ring plate 5 is lower than that of replacing the driving worm gear 43.

[0039] A metal gasket 6 is arranged between the nut of the connecting bolt 3 and the auxiliary part. The two sides of the metal gasket 6 in the thickness direction are respectively abutted against the auxiliary ring plate 5 and the nut of the connecting bolt 3. The setting of the metal gasket 6 avoids the connection instability caused by plastic parts and improves the stability of the connection between the driving worm gear 43 and the fixed plate 1.

[0040] A fixing ring 7 is coaxially fixedly connected to the bottom surface of the fixing plate 1, and a protective ring 8 is threadedly connected to the end of the fixing ring 7 away from the fixing plate 1. The bottom end of the mounting ring 431, the auxiliary ring plate 5, the metal gasket 6, and the nut of the connecting bolt 3 are all located in the protective ring 8, which protects the mounting ring 431, the auxiliary ring plate 5, the metal gasket 6, and the connecting bolt 3.

[0041] Support feet 9 are arranged on the peripheral side walls of the fixed plate 1, the bottom surface of the support feet 9 is lower than the bottom surface of the protective ring 8, and at least three support feet 9 are arranged equidistantly along the circumference of the fixed plate 1. In this embodiment, three support feet 9 are arranged equidistantly along the circumference of the fixed plate 1, which improves the stability of the support feet 9 on the rear-end collision base.

[0042] The implementation principle of an intelligent laser marking instrument rear-end base in the embodiment of the present application is:

[0043] The laser line marker is fixed on the rotating table 2 by connecting bolts 3, and then the staff puts the laser receiver at the designated position, controls the laser line marker to emit laser light through the laser remote controller, and starts the driving motor 41 at the same time. The driving motor 41 drives the driving worm 42 to rotate, drives the driving worm wheel 43 to rotate, and drives the rotating table 2 to rotate, thereby automatically driving the laser line marker to rotate until the landing point of the laser light falls on the designated position. Only one staff member is needed to complete the operation, and the operation is convenient, saving time and effort.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
