Description

Technical Field

[0001] This utility model relates to the field of four-wheel alignment technology, and in particular to a non-contact 3D laser four-wheel alignment transmitter with an angle fine-tuning mechanism. Background Technology

[0002] The non-contact 3D laser four-wheel alignment machine is an advanced testing device used for high-precision measurement of automotive wheel alignment parameters. Through laser scanning, optical imaging and 3D modeling technology, it achieves non-contact measurement of wheel spatial attitude and is widely used in automotive repair, manufacturing and testing fields. Its main structure includes a laser emitter, a resolution camera, a target board and other computer processing units.

[0003] In practical use, the angle of the laser emitting device needs to be finely adjusted according to the needs of wheel alignment. The angle of the laser emitting device in traditional laser four-wheel alignment devices is fixed and cannot be adjusted according to testing and positioning needs, which seriously limits the universality of the equipment. Under the current technical conditions, the solution adopted is to add a universal ball joint or universal joint between the laser emitting device and the support structure, and adjust the working angle by manually twisting it. However, under the action of gravity, the laser emitting device always has a tendency to deflect downwards. Over time, its accuracy will continue to decrease. At the same time, long-term deflection of the ball joint or universal joint will cause its structure to loosen, making it impossible to maintain and stabilize the working angle of the laser emitting device for a long time. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a non-contact 3D laser four-wheel positioning transmitter with an angle fine-tuning mechanism, which aims to improve the problem that the accuracy of the laser transmitter will continuously decrease due to the effect of gravity and cannot maintain and stabilize the working angle of the laser transmitter for a long time.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a non-contact 3D laser four-wheel positioning emitting device with an angle fine-tuning mechanism, comprising a crossbeam, an adjustment mechanism installed on the front side of the crossbeam, the function of the adjustment mechanism being to perform angle fine-tuning, a protective mechanism installed on the front side of the adjustment mechanism, the function of the protective mechanism being to provide protection for optical devices, the adjustment mechanism comprising a sliding block, the sliding block being slidably connected to the front outer wall of the crossbeam, a ball joint being fixedly connected to the front outer side of the sliding block, a joint seat being rotatably connected to the front side of the ball joint, a laser box being fixedly connected to the front side of the joint seat, and multiple support components being installed on the front outer wall of the sliding block.

A bottom cover plate is rotatably connected to the top front side of the protective shell. Two sliding doors are slidably connected to the middle front side of the bottom cover plate. A front cover plate is fixedly connected to the front side of the bottom cover plate. A locking assembly is installed at the bottom of the bottom cover plate.

[0010] As a further description of the above technical solution:

[0011] The locking assembly includes a buckle strip, which is fixedly connected to the bottom rear side of the bottom cover plate. A movable pin is slidably connected to the bottom of the buckle strip, and a spring is fixedly connected to the top of the movable pin.

[0012] As a further description of the above technical solution:

[0013] A column is fixedly connected to the middle of the crossbeam, and a control box is installed at the bottom of the column.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the ball joint rotates omnidirectionally within the joint seat, causing the laser box to rotate omnidirectionally with the sliding block as the base. The support components provide auxiliary support, and the hydraulic rod slides back and forth in the hydraulic pipe to adapt to the changes in the rotation angle of the laser box, helping it to overcome gravity and maintain the working angle. Multiple support components support the laser box so that it remains constrained even after multiple twists.

[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 2 and Figure 3 The present invention provides an embodiment of a non-contact 3D laser four-wheel positioning transmitter with an angle fine-tuning mechanism, comprising a crossbeam 1, an adjustment mechanism 2 installed on the front side of the crossbeam 1, the function of the adjustment mechanism 2 being to perform angle fine-tuning, and a protection mechanism 3 installed on the front side of the adjustment mechanism 2, the function of the protection mechanism 3 being to provide protection for optical components.

[0032] The adjustment mechanism 2 includes a sliding block 201, which is slidably connected to the front outer wall of the crossbeam 1. A ball joint 202 is fixedly connected to the front outer side of the sliding block 201. A joint seat 203 is rotatably connected to the front side of the ball joint 202. A laser box 204 is fixedly connected to the front side of the joint seat 203. Multiple support components 205 are installed on the front outer wall of the sliding block 201.

[0033] Multiple support components 205 each include hydraulic pipes 2051, and multiple hydraulic pipes 2051 are fixedly connected to the inner front side of the sliding block 201. Hydraulic rods 2052 are slidably connected to the inner walls of multiple hydraulic pipes 2051. A slide rail 7 is provided in the middle of the front outer wall of the crossbeam 1, which matches the shape of the sliding joint on the back of the sliding block 201. The sliding block 201 is slidably connected to the front outer wall of the crossbeam 1 through the slide rail 7.

[0034] Specifically, firstly, according to the actual positioning requirements, a force is applied to the sliding block 201 on the crossbeam 1 to make it slide until the sliding block 201 is adjusted to the appropriate distance required. The ball joint 202 is installed inside the joint seat 203 and can rotate omnidirectionally within the joint seat 203. This rotational characteristic allows the laser box 204 to rotate omnidirectionally with the sliding block 201 as the base. The horizontal deflection angle and vertical pitch angle of the laser box 204 can be adjusted according to specific usage requirements to reach the preset angle. The support component 205 is connected between the laser box 204 and the sliding block 201, playing an auxiliary support role. The hydraulic rod 2052 in the support assembly 205 is nested in the hydraulic pipe 2051 and can slide back and forth in the hydraulic pipe 2051 to adapt to the changes in the angle of each side when the laser box 204 rotates. At the same time, the hydraulic rod 2052 and the hydraulic pipe 2051 cooperate with each other to help the laser box 204 overcome the influence of its own gravity and ensure that it always maintains an appropriate working angle. Multiple support assemblies 205 are evenly distributed in different positions of the laser box 204, and together support the laser box 204, so that the laser box 204 can still be constrained by the surrounding forces after being twisted and adjusted multiple times, ensuring its positional stability.

[0035] Reference Figure 2 , Figure 4 and Figure 5 The protective mechanism 3 includes a protective shell 301, which is fixedly connected to the outer wall of the front side of the laser box 204. A bottom cover plate 302 is rotatably connected to the top front side of the protective shell 301. Two sliding doors 303 are slidably connected to the middle front side of the bottom cover plate 302. A front cover plate 304 is fixedly connected to the front side of the bottom cover plate 302. A latch assembly 305 is installed at the bottom of the bottom cover plate 302.

[0036] The locking assembly 305 includes a buckle 3051, which is fixedly connected to the rear bottom of the bottom cover plate 302. A movable pin 3052 is slidably connected to the bottom of the buckle 3051, and a spring 3053 is fixedly connected to the top of the movable pin 3052.

[0037] The top of the protective shell 301 is rotatably connected to a rotating shaft 6, and the bottom cover plate 302 is fixedly connected to the outer wall of the rotating shaft 6. The bottom cover plate 302 is rotatably connected to the top of the protective shell 301 through the rotating shaft 6. A slot 8 is provided at the bottom front side of the protective shell 301 to provide space for the buckle strip 3051 to be fastened. A light-transmitting hole 9 is provided in the middle of the front cover plate 304, which is the channel for laser penetration.

[0038] Specifically, the protective shell 301 provides a fixed base for the protective mechanism 3. The bottom cover 302 is connected to the edge of the protective shell 301 via a hinge and can be flipped up and down around the hinge axis. When the equipment is not in use, the bottom cover 302 can be manually flipped down and closed, while the two sliding doors 303 are moved to slide and close along the protective shell 301. This process protects the photosensitive elements inside the laser emitting device, preventing dust from the external environment from entering and accumulating on the surface of the elements, thus preventing dust accumulation from affecting the stability of laser emission. The locking assembly 305 is installed at the contact point between the bottom cover 302 and the protective shell 301 to assist in locking the bottom cover 302. 051 is fixed inside the bottom cover plate 302. As the bottom cover plate 302 rotates, it gradually approaches the protective shell 301 and engages with the corresponding slot on the protective shell 301. During the engagement process, the edge of the slot on the protective shell 301 presses against the moving pin 3052 on the buckle 3051. When the bottom cover plate 302 is closed in place, the buckle 3051 is no longer compressed, and the spring 3053 inside it rebounds, causing the buckle 3051 to pop out again and engage with the locking hole of the protective shell 301, thus locking the bottom cover plate 302. When it is necessary to open the bottom cover plate 302, press the moving pin 3052 to retract the buckle 3051 and disengage it from the locking hole.

[0039] Reference Figure 1 and Figure 2 A column 4 is fixedly connected to the middle of the crossbeam 1, and a control box 5 is installed at the bottom of the column 4.

[0040] Specifically, the column 4 supports the crossbeam 1 and the laser emitting device on it, providing stable height conditions for its operation. The control box 5 can stabilize the equipment and ensure that the equipment will not shake during operation, thus affecting the positioning accuracy.

[0041] Working principle: First, according to the positioning requirements, the sliding block 201 is applied to the crossbeam 1 until the appropriate distance is adjusted. The ball joint 202 rotates omnidirectionally inside the joint seat 203, so that the laser box 204 can rotate omnidirectionally with the sliding block 201 as the base. The horizontal deflection angle and vertical pitch angle are adjusted as needed. The support component 205 plays an auxiliary support role. The hydraulic rod 2052 slides back and forth in the hydraulic pipe 2051 to adapt to the changes in the angle of each side when the laser box 204 rotates. At the same time, the two can help the laser box 204 overcome gravity and always maintain an appropriate working angle. Multiple support components 205 support the laser box 204, so that the laser box 204 can still receive the constraint force from its surroundings after being twisted multiple times. This mechanism ensures that the laser box 204 can adjust the angle omnidirectionally, and the accuracy is not affected by gravity. Moreover, the angle stability will not decrease after multiple adjustment movements. It solves the problem in the prior art that the accuracy will continuously decrease due to the effect of gravity and cannot maintain and stabilize the working angle of the laser emitting device for a long time.

[0042] The protective shell 301 provides a fixed base for the protection mechanism 3. The bottom cover 302 can be flipped up and down and can be closed when the equipment is not in use. At the same time, the two sliding doors 303 are slidably closed to protect the photosensitive elements inside the laser emitting device and prevent dust accumulation from affecting laser emission. The locking assembly 305 assists in locking the bottom cover 302 to keep it closed. The buckle 3051 engages with the protective shell 301 as the bottom cover 302 rotates. The protective shell 301 presses the moving pin 3052. When it is closed, the buckle 3051 pops out again under the rebound of the spring 3053 to complete the locking. When the bottom cover 302 needs to be opened, the moving pin 3052 can be pressed. This mechanism provides an additional protective layer for the laser box 204, which can protect the laser emitting device and further ensure the accuracy of four-wheel positioning.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
