Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see the appendix Figure 1 -Appendix Figure 5 A clamp for holding and aligning a laser emitter includes a support frame 1. The support frame includes a horizontally arranged support base plate 103. A laser spot distribution pattern 104 is provided on the support base plate. The laser spot distribution pattern consists of several concentric circles 105 with an origin 106 as the reference point. The origin is coaxial with the support cylinder, and each concentric circle is equally spaced at 5mm intervals. When laser light is projected downwards onto the laser spot distribution pattern, the light spots fall between the concentric circles, indicating the degree of deviation from the origin.

[0023] The base plate has two symmetrically arranged support columns 101, and a vertically arranged support cylinder 3 is provided between the two support columns. A support ring 4 is provided on the outside of the support cylinder, and both sides of the outer ring of the support ring are connected to the support columns through connecting plates. A support platform is provided on the outside of the support cylinder, and the support platform and the support ring 4 are supported together. The support cylinder is stably supported by the support ring.

[0024] An infrared camera 2 is installed at the bottom of the support cylinder. The infrared camera 2 is electrically connected to the power supply 907 and signal-connected to the controller 906.

[0025] The infrared camera 2 captures the position of the laser spot in real time and feeds the data back to the controller. The controller precisely controls the adjustment fixture to make the laser spot shine downward onto the origin 106 of the laser spot distribution map.

[0026] The top of the support cylinder is equipped with an adjustment clamp, which includes an annular mounting plate 5 installed on the top of the support cylinder. The adjustment clamp is fixed to the top of the support cylinder by the annular mounting plate, and the adjustment clamp is fixed and stable.

[0027] The annular mounting plate is provided with a positioning cylinder 501 and a positioning flange 701. Above the positioning flange is an adjustment flange 704 arranged parallel to the positioning flange. An adjustment space is provided between the positioning flange 701 and the adjustment flange 704. The vertical alignment component includes a lifting frame 902, with lifting sliders 991 symmetrically arranged at both ends of the lifting frame. Each lifting slider 991 is slidably fitted with a vertical guide rail 102. The lifting frame includes an annular frame body, with a plurality of mounting slots 921 arranged circumferentially on the annular frame body. The three sides of the mounting box are fitted with the inner grooves of the mounting slots 921.

[0028] The vertical guide rail 102 is set on the corresponding support column 101, and the support column is equipped with a lifting cylinder 909, the shaft end of the lifting cylinder is connected to the lifting slider 991.

[0029] Depending on the actual situation, when adjusting the height of the lifting frame 902, the lifting cylinder 909 is activated, driving the lifting slider to slide up and down along the vertical guide rail 102, thereby driving the lifting frame to perform lifting and lowering movements to meet different lifting and lowering requirements of the lifting frame.

[0030] The laser emitter 8 is vertically installed from top to bottom along the adjustment flange hole. The adjustment flange and the positioning flange are provided with four vertical adjustment holes arranged vertically and vertically. A vertical adjustment bolt 702 is inserted through the vertical adjustment hole. A compression spring 703 in a compressed state is sleeved on the vertical adjustment bolt. A vertical adjustment component 9 for adjusting each vertical adjustment bolt is provided above the adjustment flange. The vertical alignment component 9 also includes four screwing parts disposed on the lifting frame, each screwing part including a first screwing head 904, the first screwing head being in contact with the vertical alignment bolt; A servo motor 903 is positioned above the first rotating head, with its shaft connected to the rotating head. A first angle encoder 908 is mounted on the servo motor shaft 905. A mounting box 901 is located on one side of the servo motor, containing a power supply 907 and a controller 906. The leveling motor 602, servo motor 903, lifting cylinder 909, infrared camera 2, first angle encoder 908, and second angle encoder 603 are electrically connected to the power supply. These components are also connected to the controller signal.

[0031] When the lifting frame is adjusted to the appropriate height, the infrared camera 2 captures the position of the laser spot in real time. If the laser spot deviates from the origin, the infrared camera 2 sends data back to the controller. The controller precisely controls the servo motors, causing the laser spot to shift to one side. The servo motor 903 on the corresponding side of the shifted spot starts, driving the first screwing head 904 to rotate clockwise, thus tightening the vertical alignment bolts. Based on real-time monitoring by the first angle encoder 908, the screwing angle and number of turns of the vertical alignment bolts are precisely adjusted. Each servo motor 903 starts and stops independently, controlling the screwing angle and number of turns of each vertical alignment bolt, ultimately achieving overall leveling.

[0032] The adjusting flange is provided with radial adjusting holes along the radial direction. The radial adjusting assembly 6 includes a horizontally arranged regular polygonal support frame. The support frame 601 and the adjusting flange 704 are set at the same height. The outer sides of the support frame are fixed to the corresponding support columns 101 by connecting blocks. Each frame of the support frame is equipped with a leveling motor 602. The shaft end of the leveling motor is equipped with a second screwing head 604. The second screwing head 604 is in contact with the radial adjustment bolt 705. The shaft of the leveling motor is equipped with a second angle encoder 603.

[0033] The radial adjustment holes and the vertical adjustment holes are staggered circumferentially. The radial adjustment holes are equipped with radial adjustment bolts 705. The adjustment flange is equipped with radial adjustment components 6 for adjusting each radial adjustment bolt circumferentially.

[0034] The laser emitter 8 is vertically installed from top to bottom along the alignment flange hole. First, manually suspend the laser emitter 8 temporarily and place it into the alignment flange hole.

[0035] First, start all the leveling motors 602 so that the bolt heads of the radial alignment bolts clamp the laser emitter 8 tube body circumferentially, ensuring that the laser emitter 8 is vertically suspended.

[0036] According to the real-time capture of the laser spot position by the infrared camera 2, when the laser spot does not hit the origin position and deviates from the origin, the infrared camera 2 feeds back data to the controller. The controller precisely controls the leveling motor 602, and the laser spot shifts to one side. The leveling motor 602 on the side corresponding to the shift of the spot starts. Each leveling motor 602 starts and stops independently, driving the radial alignment bolt to be tightened. The shaft end of the leveling motor drives the second tightening head 604, which tightens the radial alignment bolt 705. During the rotation, the second angle encoder 603 detects the tightening angle and the number of turns of the vertical alignment bolt.

[0037] The leveling motor 602 continuously starts and stops, fine-tuning the tightening of each vertical alignment bolt 702. Simultaneously, the servo motor starts and stops, controlling each vertical alignment bolt to ultimately achieve overall leveling. This ensures that the laser beam emitted by the laser emitter is precisely aligned with the origin.
