[0024] The embodiment of the utility model provides a laser coaxiality online monitoring device.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , including a laser 1, a bottom plate 5 is rotatably provided at the bottom of the laser 1, a fixing plate 9 is fixedly connected to one side of the top of the bottom plate 5, an adjusting bolt 17 is threadedly connected to the fixing plate 9, a pressure sensor 14, a fixing seat 10 and a transmission hemisphere 18 are provided at one end of the adjusting bolt 17, a connecting thin rod 19 is fixedly connected between one end of the adjusting bolt 17 and the transmission hemisphere 18, a reserved groove 12 is provided at one side of the fixing seat 10, a contact plate 15 is provided at one side of the pressure sensor 14, and a push spring 16 is fixedly connected to one side of the contact plate 15.

[0026] When the utility model is in use: after the position of the bottom plate 5 is installed and fixed, a fixed shaft 4 is fixedly connected to one side of the bottom of the laser 1, and a mounting seat 3 rotatably sleeved outside the fixed shaft 4 is fixedly connected to the top of the bottom plate 5, the laser 1 can be installed on the top of the laser 1, and the laser 1 can rotate with the fixed shaft 4 as a rotation fulcrum.

[0027] When the coaxiality of the laser 1 needs to be adjusted, the adjusting bolt 17 is operated to rotate. Since the adjusting bolt 17 is threadedly connected to the fixing plate 9, the direction of movement of the connecting rod 19 fixed at one end of the adjusting bolt 17 can be controlled by controlling the rotation direction of the adjusting bolt 17, so that the connecting rod 19 is close to the fixing plate 9 or away from the fixing plate 9. An empty slot 13 is provided inside the fixing seat 10, and one end of the connecting rod 19 is fixedly connected to the transmission hemisphere 18 arranged inside the reserved slot 12, so the connecting rod 19 drives the transmission hemisphere 18 to move and adjust the position of the transmission hemisphere 18. When the rotation direction of the adjusting bolt 17 is controlled to make the connecting rod 19 away from the fixing plate 9, the transmission hemisphere 18 will push the laser 1 to rotate counterclockwise about the fixed axis 4 position axis (clockwise and counterclockwise in this application are used as the rotation direction). Figure 1 When the connecting rod 19 is close to the fixing plate 9, the transmission hemisphere 18 pulls the fixing seat 10 on which the laser 1 is fixed, so that the laser 1 rotates clockwise about the fixed axis 4, and the coaxiality of the laser 1 can be adjusted simply and easily. By adjusting the coaxiality by adjusting the overall angle of the laser 1, the labor cost can be reduced.

[0028] In addition, the connecting thin rod 19 is partially arranged inside the pressure sensor 14, and the connecting thin rod 19 passes through the empty slot 13. When the fixing seat 10, which is arranged as a long strip of the empty slot 13, moves synchronously with the laser 1, it will not contact the connecting thin rod 19. The reserved slot 12 and the inner diameter of the pressure sensor 14 are both relatively large, and the transmission hemisphere 18 will not affect the rotational movement of the laser 1. One end of the adjusting bolt 17 is arranged inside the pushing spring 16, and the pushing spring 16 is limited by the adjusting bolt 17, limiting the trajectory of the pushing spring 16 pushing the contact plate 15 to move.

[0029] A groove is provided on one side of the fixing plate 9, and one end of the push spring 16 is arranged inside the groove and fixedly connected to the fixing plate 9, so the push spring 16 fixed by the fixing plate 9 pushes the contact plate 15, so that the contact plate 15 contacts one side of the pressure sensor 14. Since the pressure sensor 14 is fixedly connected inside the fixing seat 10, the pressure sensor 14 will move synchronously with the laser 1. When the position adjustment of the laser 1 is completed, the pressure sensor 14 also moves accordingly, and the position of the push spring 16 from the pressure sensor 14 will also change, so the pressure detected by the pressure sensor 14 will also change. When the laser 1 is displaced during use and the coaxiality changes, the pressure sensor 14 detects a change in the pressure value. The staff can judge the data of the coaxiality change based on the detected pressure value, provide data support for adjusting the laser 1, and quickly reset the laser 1, shortening the time investment required for adjusting the coaxiality of the laser 1. Only by changing the timed manual detection can the coaxiality change of the laser 1 be discovered, and the need for real-time online monitoring of the coaxiality change of the laser 1 is realized.

[0030] A plurality of fixing bolts 11 are threadedly connected between the fixing base 10 and the laser 1 . The fixing base 10 installed by the plurality of fixing bolts 11 can be quickly installed and removed, ensuring that the laser 1 can be easily installed and removed from the top of the base plate 5 .

[0031] Since a mounting shell 8 is fixedly connected to the side of the bottom of the laser 1 away from the fixed axis 4, and a magnet guide rail 6 is sleeved on the outer side of the metal ball 7 arranged inside the mounting shell 8, the metal ball 7 that can rotate inside the mounting shell 8 is limited by the magnet guide rail 6 fixedly connected to the laser 1, and the movement of the laser 1 can be supported, ensuring that both sides of the bottom of the laser 1 are supported, and ensuring the stability of the operation of the laser 1. In addition, the magnet guide rail 6 uses magnetic force to absorb and fix the iron metal ball 7, limit the laser 1, and slow down the speed of coaxiality change during the use of the laser 1.

[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
