[0031] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0032] Example 1

[0033] refer to Figure 1 As shown, an embodiment of the present application provides a laser alignment device 100 , which includes a laser alignment component 110 , a cable assembly 120 and a second fixing component 130 .

[0034] Specifically, combined Figure 2 and Figure 3As shown, the laser collimator 110 includes a fixing ring 111 and a first fixing member 112, the laser collimator 110 defines a cavity 113, the cavity 113 is provided with a through hole 114, the fixing ring 111 and the first fixing member 112 are both arranged in the cavity 113, and the first fixing member 112 is located on the side of the fixing ring 111 away from the through hole 114; the cable assembly 120 includes a cable housing 121, a connecting rope 122 and an optical fiber assembly 123, the cable housing 121 is a hollow tube body, one end of the cable housing 121 is penetrated through the through hole 114 and connected to the fixing ring 111, the connecting rope 122 and the optical fiber assembly 123 are both arranged in the cable housing 121, and the connecting rope 122 and the optical fiber assembly 123 are arranged in parallel, one end of the connecting rope 122 is connected to the fixing ring 111, and one end of the optical fiber assembly 123 passes through the fixing ring 111 And it is connected to the first fixing piece 112; the second fixing piece 130 is connected to the end of the connecting rope 122 away from the fixing ring 111, the connecting rope 122 is fixed by the fixing ring 111 of the laser collimator 110, and the optical fiber assembly 123 is connected by the first fixing piece 112, the cable housing 121 is used to set the connecting rope 122 and the optical fiber assembly 123, the connecting rope 122 and the optical fiber assembly 123 are arranged in parallel, the connecting rope 122 protects the optical fiber assembly 123, and the end of the connecting rope 122 away from the fixing ring 111 is connected to the second fixing piece 130. When the connecting rope 122 is in a stretched state, when the cable housing 121 is stretched or bent, the connecting rope 122 can offset the stress deformation of the cable housing 121 to reduce the bending and stretching of the optical fiber assembly 123, avoid the entanglement and expansion and contraction deformation of the optical fiber assembly 123, reduce the damage of the optical fiber assembly 123, and improve the product quality of the laser collimator 100.

[0035] It should be noted that collimation means that the centers or reference points of the objects under investigation are in the same straight line. The installation of large aircraft and ship equipment, the installation of large generator rotors and other large mechanical equipment require alignment. The construction process of subways, tunnels and large underground pipelines also requires alignment. The laser collimation device 100 uses a laser beam as a directional emission to form a beam in space as a collimation reference line to calibrate a straight line.

[0036] Optionally, the connecting rope 122 and the optical fiber assembly 123 are abutted against each other. It can be understood that at this time, the connecting rope 122 is in a stretched state, which offsets the tensile deformation of the cable housing 121, so that the connecting rope 122 has a certain limiting and protective effect on the optical fiber assembly 123. When the cable housing 121 is stretched or slightly bent during use, the connecting rope 122 can reduce the entanglement and expansion and contraction deformation of the optical fiber assembly 123.

[0037] In one embodiment, specifically, Figure 3 As shown, the fixing ring 111 can be sleeved on the cable housing 121 , and the fixing ring 111 is fixedly connected to the cable housing 121 . The fixing ring 111 is installed in the cavity 113 of the laser collimator 110 , and is used to connect and fix the cable housing 121 .

[0038] Optionally, a limit step is formed at the connection position between the cavity 113 and the through hole 114, and the fixing ring 111 is arranged opposite to the limit step. Since the cable housing 121 is in a stretched state during the use of the laser alignment device 100, the position of the fixing ring 111 is limited by the limit step when the fixing ring 111 becomes loose.

[0039] Optionally, the fixing ring 111 can abut against the side wall of the cavity 113, that is, the size of the cavity 113 matches the size of the fixing ring 111. Exemplarily, there is a gap between the fixing ring 111 and the first fixing member 112, and there is a certain distance between the fixing ring 111 and the first fixing member 112.

[0040] Optionally, the cable housing 121 abuts against the wall of the through hole 114 so that the cable housing 121 closes the through hole 114, preventing external dust particles and foreign objects from entering from the connection position between the cable housing 121 and the through hole 114, causing performance degradation or loss of the laser collimator 110, thereby affecting the product quality of the laser collimator 110.

[0041] In one embodiment, specifically, the cable assembly 120 is an armored cable, and the cable housing 121 is an armored tube. It should be noted that the armored cable is a solid assembly made of conductors of different materials installed in a metal sleeve of insulating material, and is processed into a bendable body. The armored tube is a centrally controlled tube body, and the armored tube can be added to cables of any structure to increase the mechanical strength of the cable and improve the anti-corrosion ability.

[0042] Optionally, the second fixing member 130 may be a laser water cooling plate, and the second fixing member 130 can fix the connecting rope 122 . The laser water cooling plate is used to cool down and dissipate the heat of the laser device and the optical fiber.

[0043] In summary, the laser alignment device 100 fixes the connecting rope 122 through the fixing ring 111 of the laser alignment component 110, connects the optical fiber assembly 123 through the first fixing component 112, and the cable housing 121 is used to set the connecting rope 122 and the optical fiber assembly 123. The connecting rope 122 and the optical fiber assembly 123 are set in parallel. The connecting rope 122 protects the optical fiber assembly 123. The end of the connecting rope 122 away from the fixing ring 111 is connected to the second fixing component 130. When the connecting rope 122 is in a stretched state, when the cable housing 121 is stretched or bent, the connecting rope 122 can offset the stress deformation of the cable housing 121 to reduce the bending and stretching of the optical fiber assembly 123, avoid entanglement and expansion and contraction deformation of the optical fiber assembly 123, reduce damage to the optical fiber assembly 123, and improve the product quality of the laser alignment device 100.

[0044] Example 2

[0045] refer to Figures 1 to 3 As shown, an embodiment of the present application provides another laser alignment device 100 , which includes a laser alignment component 110 , a cable assembly 120 and a second fixing component 130 .

[0046] Specifically, combined Figure 2 and Figure 3 As shown, the laser collimator 110 includes a fixing ring 111 and a first fixing member 112. The laser collimator 110 defines a cavity 113. The cavity 113 is provided with a through hole 114. The fixing ring 111 and the first fixing member 112 are both arranged in the cavity 113, and the first fixing member 112 is located on the side of the fixing ring 111 away from the through hole 114. The connecting rope 122 is fixed by the fixing ring 111 of the laser collimator 110, and the optical fiber assembly 123 is connected by the first fixing member 112.

[0047] Specifically, the cable assembly 120 includes a cable housing 121, a connecting rope 122 and an optical fiber assembly 123, the cable housing 121 is a hollow tube, one end of the cable housing 121 is passed through the through hole 114 and is connected to the fixing ring 111, the connecting rope 122 and the optical fiber assembly 123 are both arranged in the cable housing 121, and the connecting rope 122 and the optical fiber assembly 123 are arranged in parallel, one end of the connecting rope 122 is connected to the fixing ring 111, one end of the optical fiber assembly 123 passes through the fixing ring 111 and is connected to the first fixing member 112; the second fixing member 130 is connected to the connecting rope 1 22 is connected to one end away from the fixing ring 111, and the cable housing 121 is used to set a connecting rope 122 and an optical fiber assembly 123. The connecting rope 122 and the optical fiber assembly 123 are set in parallel. The connecting rope 122 protects the optical fiber assembly 123. The end of the connecting rope 122 away from the fixing ring 111 is connected to the second fixing member 130. When the connecting rope 122 is in a stretched state, when the cable housing 121 is stretched or bent, the connecting rope 122 can offset the stress deformation of the cable housing 121 to reduce the bending and stretching of the optical fiber assembly 123, avoid entanglement and expansion and contraction deformation of the optical fiber assembly 123, and reduce damage to the optical fiber assembly 123.

[0048] Optionally, the connecting rope 122 and the optical fiber assembly 123 are abutted against each other, so that the connecting rope 122 has a certain limiting and protective effect on the optical fiber assembly 123. When the cable housing 121 is stretched or slightly bent during use, the connecting rope 122 can reduce the entanglement and expansion and contraction deformation of the optical fiber assembly 123.

[0049] In this embodiment, the connecting rope 122 can be made of one of a steel rope, a steel wire or a copper wire. The connecting rope 122 can also be a rope wire made of other materials to achieve a better connection stretching effect.

[0050] In one embodiment, specifically, Figure 3 As shown, the fixing ring 111 can be sleeved on the cable housing 121, and the fixing ring 111 is fixedly connected to the cable housing 121. It can be understood that the fixing ring 111 is an annular structure, and the fixing ring 111 is installed in the cavity 113 of the laser collimator 110. The fixing ring 111 is used to connect and fix the cable housing 121. Further, the fixing ring 111 can be fixed by bolts.

[0051] Optionally, a limiting step is formed at the connection position between the cavity 113 and the through hole 114, and the fixing ring 111 is arranged relative to the limiting step. It can be understood that the size of the fixing ring 111 is larger than the diameter of the through hole 114, that is, since the cable housing 121 is in a stretched state during the use of the laser alignment device 100, the position of the fixing ring 111 is limited by the limiting step when the fixing ring 111 becomes loose, so as to prevent the fixing ring 111 and the cable housing 121 from falling out of the through hole 114.

[0052] Optionally, the fixing ring 111 can abut against the side wall surface of the cavity 113, that is, the size specification of the cavity 113 matches the size specification of the fixing ring 111. Further, the fixing ring 111 can be fixed to the side wall surface of the cavity 113 by bolts to locate the position of the fixing ring 111.

[0053] Optionally, there is a gap between the fixing ring 111 and the first fixing member 112 , and there is a certain distance between the fixing ring 111 and the first fixing member 112 . The fixing ring 111 does not hinder the first fixing member 112 , and the two do not affect each other.

[0054] In one embodiment, specifically, in combination Figure 3 and Figure 4As shown, the aperture of the through hole 114 is D1, and the inner diameter of the fixing ring 111 is D2, satisfying D1≤D2≤1.3D1, that is, the inner diameter D2 of the fixing ring 111 is greater than or equal to the aperture D1 of the through hole 114, so that the cable housing 121 can pass through the through hole 114 and then be inserted into the fixing ring 111 to connect the cable housing 121 with the fixing ring 111; the inner diameter D2 of the fixing ring 111 is less than or equal to 1.3D1, and the size specification of the inner diameter D2 of the fixing ring 111 is within a certain range, thereby reducing the situation where the inner diameter D2 of the fixing ring 111 is too large to be fixed to the cable housing 121, facilitating the connection of the cable housing 121 to the fixing ring 111, and avoiding the loosening of the connection position of the cable housing 121. For example, D1 is 30mm and D2 is 30mm. At this time, the size of the cable housing 121 matches the size of the through hole 114. The cable housing 121 can pass through the through hole 114, and the cable housing 121 is inserted into the fixing ring 111 and connected to the fixing ring 111, so that the fixing ring 111 fixes the cable housing 121. In addition, D1 can also be 35mm and D2 can be 40mm, so that a certain gap can be kept when the cable housing 121 is inserted into the fixing ring 111. The size of the gap is small, so that the cable housing 121 and the fixing ring 111 can be connected without large-scale relative movement. Of course, the size of H and h is not limited to this. In other embodiments, when D1 is 37mm, D2 can also be 37mm; when D1 is 40mm, D2 can also be 40mm, 42mm, 45mm, 50mm, 52mm, etc., which will not be listed here.

[0055] Optionally, the cable housing 121 abuts against the wall of the through hole 114 so that the cable housing 121 closes the through hole 114, and prevents external dust particles and foreign objects from entering from the connection position between the cable housing 121 and the through hole 114, causing the performance of the laser collimator 110 to degrade or be lost, thereby affecting the product quality of the laser collimator 110. It can be understood that when the cable housing 121 is in a straightened state, the wall of the through hole 114 will not limit the cable housing 121, but will close the through hole 114 to play a protective role.

[0056] In one embodiment, specifically, the cable assembly 120 is an armored cable, and the cable housing 121 is an armored tube. Optionally, the second fixing member 130 may be a laser water cooling plate, and the second fixing member 130 may fix the connecting rope 122. The laser water cooling plate is used to cool and dissipate heat for the laser device and the optical fiber. Furthermore, the laser water cooling plate may fix the connecting rope 122 by bolts.

[0059] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0060] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention.
