[0030] 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 protection scope of the present utility model.
[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a 3D laser four-wheel alignment optical device with rapid calibration function, including a fixed rod 1. A calibration mechanism 2 is slidably connected to one side of the outer wall of the fixed rod 1 for rapid calibration. An adjustment mechanism 3 is fixedly connected to the bottom of the outer wall of the fixed rod 1 for adjusting the support position. The calibration mechanism 2 includes a movable frame 201, which is slidably connected to the middle of the inner wall of the fixed rod 1. An adjustment frame 202 is rotatably connected to one side of the outer wall of the movable frame 201, and a telescopic frame 203 is rotatably connected to the other side of the adjustment frame 202. A fixed plate 204 is fixedly connected to the middle of the inner wall of the telescopic frame 203, and a support is rotatably connected to one side of the outer wall of the fixed plate 204. A drive assembly 206 is rotatably connected to the other side of the outer wall of the support plate 205. The drive assembly 206 includes a hydraulic push rod 2061, which is fixedly connected to the middle of the inner wall of the telescopic frame 203. A movable plate 2062 is fixedly connected to the output end of the hydraulic push rod 2061. The movable plate 2062 is fixedly connected to one side of the outer wall of the fixed plate 204. A motor 2063 is fixedly connected to the other side of the outer wall of the movable plate 2062. A worm gear 2064 is fixedly connected to the output end of the motor 2063. A worm wheel 2065 is rotatably connected to the middle of the inner wall of the support plate 205. The worm wheel 2065 meshes with the worm gear 2064. A movable groove 2066 is slidably connected to the middle of the inner wall of the support plate 205.
[0032] Specifically, when the 3D laser four-wheel alignment optical device with rapid calibration function is working, the fixed rod 1 is the basic support component, and the calibration mechanism 2, which is slidably connected to the adjacent side of its outer wall, is responsible for rapid calibration. In the calibration mechanism 2, the movable frame 201 can slide along the middle of the inner wall of the fixed rod 1, providing a basis for the initial adjustment of the calibration position; the adjusting frame 202, which is rotatably connected to one side of the outer wall of the movable frame 201, can rotate to change its angle, and the telescopic frame 203, which is rotatably connected to the other side, can extend and retract its length to further adjust the calibration range. The fixed plate 204 in the middle of the inner wall of the telescopic frame 203 provides a mounting base for the support plate 205. One side of the support plate 205 is rotatably connected to the fixed plate 204, and the other side is connected to the drive assembly 206. In the drive assembly 206, the hydraulic push rod 2061 is fixed to the middle of the inner wall of the telescopic frame 203. Its output end pushes or pulls the moving plate 2062, causing the fixed plate 204 and connected components to move. After the motor 2063 starts, it drives the worm gear 2064 to rotate. Because the worm gear 2064 meshes with the worm wheel 2065, the worm wheel 2065 rotates accordingly. This allows for fine adjustment of the position of the support plate 205 through the moving groove 2066, completing rapid calibration. In addition, the adjustment mechanism 3 at the bottom of the outer wall of the fixed rod 1 can adjust the equipment support position to cooperate with the calibration work and ensure stable operation of the equipment.
[0033] Reference Figure 1 , Figure 2 and Figure 5 The adjustment mechanism 3 includes a support frame 301, which is connected through the middle of the inner wall of the fixed rod 1. A connecting plate 302 is slidably connected to the adjacent side of the outer wall of the support frame 301. A rack 303 is slidably connected to the top of the outer wall of the support frame 301. A gear 304 is rotatably connected to the top of the inner wall of the support frame 301. The gear 304 meshes with the rack 303. A connecting assembly 305 is fixedly connected to the middle of the inner wall of the support frame 301. The connecting assembly 305 includes a motor 3051, which is fixedly connected to the bottom of the inner wall of the support frame 301. A pull rope 3052 is fixedly connected to the output end of the motor 3051. A fixing ring 3053 is fixedly connected to the other end of the pull rope 3052. A fixing buckle 3054 passes through the middle of the inner wall of the fixing ring 3053. A connecting block 3055 is fixedly connected to the top of the outer wall of the fixing buckle 3054.
[0034] Specifically, when the adjustment mechanism 3 is working, the core component support frame 301 is connected through the middle of the inner wall of the fixed rod 1, providing basic installation and support. When position adjustment is required, the connecting plate 302 on the adjacent side of the outer wall of the support frame 301 can slide along its outer wall to achieve lateral adjustment to adapt to connection requirements. For vertical adjustment, the rack 303 at the top of the outer wall of the support frame 301 meshes with the gear 304 at the top of the inner wall. When the gear 304 rotates, it drives the rack 303 to slide along the top of the outer wall, realizing the lifting and lowering of the component. The connecting component 305 is the key to power and transmission. After the motor 3051 at the bottom of the inner wall of the support frame 301 is started, it drives the pull rope 3052 to retract, and the fixing ring 3053 at the other end of the pull rope 3052 moves accordingly, driving the connecting block 3055 to move through the fixing buckle 3054. The fixing buckle 3054 cooperates with other components to achieve position fixation or adjustment under the action of the pull rope 3052. Finally, all components work together to complete the overall adjustment of the adjustment mechanism 3.
[0035] Reference Figure 1 , Figure 2 and Figure 3 A hook 4 is rotatably connected to one side of the outer wall of the adjustment frame 202. A pad 5 is fixedly connected to the upper and lower sides of the inner wall of the telescopic frame 203. A support leg 6 is fixedly connected to the bottom of the outer wall of the support frame 301. Foot pads 7 are fixedly connected to the front and rear sides of the bottom of the support leg 6. A cover 8 is fixedly connected to the top of the inner wall of the support frame 301. A screw 9 is threadedly connected to one side of the outer wall of the fixing buckle 3054. A lever 11 is rotatably connected to one side of the outer wall of the support frame 301. A pin 10 is rotatably connected to the right side of the inner wall of the lever 11.
[0036] Specifically, during the operation of this device, the hook 4, rotatably connected to one side of the outer wall of the adjusting frame 202, can be rotated to adjust its position, facilitating the hanging of related objects for fixing or suspending operations. The pads 5 fixed to the upper and lower sides of the inner wall of the telescopic frame 203 provide cushioning and support for its internal structure during telescopic movement, reducing direct friction and collision between components and ensuring stability during the telescopic process. The support legs 6 fixed to the bottom of the outer wall of the support frame 301, together with the foot pads 7 fixed to its front and rear sides, provide a stable support foundation for the entire device. The foot pads 7 increase friction with the contact surface, preventing the device from sliding during operation. The cover 8 fixed to the top of the inner wall of the support frame 301 protects its internal structure. When the position or state of the fixing buckle 3054 needs adjustment, the tightness of the fixing buckle 3054 can be adjusted by turning the screw 9 threaded on one side of its outer wall, thereby completing the fixing or loosening operation of the related connecting components. In addition, rotating the lever 11 on one side of the outer wall of the support frame 301 will cause the pin 10 connected to the inner right side of the support frame to change position. The movement of the pin 10 can lock or unlock the relevant parts of the support frame 301, thereby cooperating with the device to complete the corresponding adjustment and positioning work and ensuring the coordinated operation of each mechanism.
[0037] Working Principle: When this 3D laser four-wheel alignment optical device with rapid calibration function is in operation, the fixed rod 1 serves as the basic load-bearing component, and the calibration mechanism 2, slidably connected to its outer wall on one side, is responsible for the rapid calibration operation. In the calibration mechanism 2, the movable frame 201 can slide along the middle of the inner wall of the fixed rod 1, providing a basis for the initial adjustment of the calibration position; the adjusting frame 202, rotatably connected to one side of the outer wall of the movable frame 201, can change its angle by rotation, while the telescopic frame 203, rotatably connected to the other side of the adjusting frame 202, can extend or retract in length to further adjust the calibration range. The fixed plate 204, fixed in the middle of the inner wall of the telescopic frame 203, provides an installation base point for the support plate 205. One side of the outer wall of the support plate 205 is rotatably connected to the fixed plate 204, and the other side is connected to the drive assembly 206. In the drive assembly 206, the hydraulic push rod 2061 is fixed in the middle of the inner wall of the telescopic frame 203. Its output end pushes or pulls the movable plate 2062 fixed on one side of the outer wall of the fixed plate 204, thereby moving the fixed plate 204 and its connected components. After the motor 2063 on the other side of the outer wall of the movable plate 2062 is started, its output end drives the worm gear 2064 to rotate. Since the worm gear 2064 meshes with the worm wheel 2065 rotatably connected in the middle of the inner wall of the support plate 205, the worm wheel 2065 will rotate accordingly. Then, through the movable groove 2066 slidably connected in the middle of the inner wall of the support plate 205, the position of the support plate 205 can be finely adjusted to complete the rapid calibration. The adjustment mechanism 3 fixed at the bottom of the outer wall of the fixed rod 1 can adjust the support position of the equipment to cooperate with the calibration work and ensure the overall stable operation of the equipment.
[0038] When the adjustment mechanism 3 is in operation, its core component, the support frame 301, is connected through the middle of the inner wall of the fixed rod 1, providing a basic installation and support carrier for the entire mechanism. When position adjustment is required, the connecting plate 302, which is slidably connected to the adjacent side of the outer wall of the support frame 301, can slide along the outer wall of the support frame 301 to achieve lateral position adjustment to adapt to different connection requirements. In terms of vertical adjustment, the rack 303, which is slidably connected to the top of the outer wall of the support frame 301, and the gear 304, which is rotatably connected to the top of the inner wall, form a meshing transmission structure. When the gear 304 rotates, it will drive the meshing rack 303 to slide along the top of the outer wall of the support frame 301, thereby realizing the lifting and lowering adjustment of the relevant components. As a key part of power and transmission, the connecting assembly 305, whose motor 3051 is fixed to the bottom of the inner wall of the support frame 301, will drive the pull rope 3052 to retract after starting. The fixed ring 3053 connected to the other end of the pull rope 3052 will move accordingly, thereby driving the top fixed connecting block 3055 to move through the fixed buckle 3054 that passes through the middle of its inner wall. At the same time, the fixed buckle 3054 can be fixed or adjusted in position under the action of the pull rope 3052 by cooperating with other components. Through the coordinated operation of various components, the overall adjustment function of the adjustment mechanism 3 is completed.
