Description
Technical Field
[0001] This invention relates to the field of laser positioning technology, specifically to a laser positioning device. Background Technology
[0002] A laser positioning instrument is a device that uses laser technology for spatial positioning and is widely used in various fields such as industrial manufacturing, scientific research experiments, and construction. With the continuous advancement of technology, the demand for precise spatial positioning is increasing, and the importance of laser positioning instruments as a high-precision positioning tool is becoming increasingly prominent.
[0003] Most existing laser positioning devices use worm gear transmission, but the equipment is bulky and suffers significant wear during operation, affecting its service life. Therefore, we propose a laser positioning device. Summary of the Invention
[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a laser positioning device that solves the problem that most existing laser positioning devices use worm gear transmission, which results in large device size and significant wear during operation, affecting the device's service life.
[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a laser positioning device includes a housing, an mounting plate fixedly connected to the inner wall of the housing, a carrier plate rotatably connected to the inner wall of the mounting plate, a focusing assembly mounted on the carrier plate, and an adjustment assembly provided on the carrier plate. The adjustment assembly includes a control frame, which is fixedly connected to one side of the carrier plate. A telescopic rod is fixedly connected to one side of the control frame, and the driving end of the telescopic rod passes through the control frame. A clamp is fixedly connected to the side of the mounting plate near the control frame, and a limit hole is formed in the inner wall of the clamp. The driving end of the telescopic rod extends into the clamp, and a locking rod is fixedly connected to the surface of the telescopic rod, with the locking rod located in the limit hole. The adjustment assembly interfaces with an external control signal through the control plate, enabling automated fine-tuning via the telescopic rod. The operation is efficient and precise. Simultaneously, the washers prevent direct collision between the control frame and the clamp during adjustment, and the springs always provide a reverse tension, ensuring no jamming during telescopic rod drive and preventing angular deviation due to vibration after adjustment. Combined with the fastening of the housing and panel by the mounting bolts, the overall stability of the device operation is further guaranteed.
[0006] Furthermore, a washer is fixedly connected to the side of the control frame near the card holder, and the drive end of the telescopic rod passes through the washer. The adjustment component pushes the card rod to move along the limiting hole with the help of the telescopic rod. The control frame drives the carrier plate and focusing component to rotate precisely, thereby realizing the fine adjustment of the laser focusing direction.
[0007] Furthermore, a spring is fixedly connected to the side of the washer away from the control frame, and the end of the spring away from the washer is fixedly connected to the surface of the card holder. This effectively compensates for the lack of precision of single adjustment. Combined with the spring's fitting and limiting effect on the card rod, it can significantly improve the angular accuracy and precision of laser positioning, meeting the high-precision positioning needs in various scenarios such as vehicle and industrial applications.
[0008] Furthermore, the longitudinal section of the control frame is "L" shaped. The driving end of the telescopic rod pushes the locking rod, which drives the carrier plate and focusing assembly to rotate through the control frame. The focusing assembly is finely adjusted by adjusting the component. The control board receives an external control signal through an interface to control the telescopic rod to start. The driving end of the telescopic rod pushes the locking rod to move along the limiting hole on the inner wall of the bracket, while simultaneously driving the "L" shaped control frame to move synchronously. Since the control frame is fixedly connected to the carrier plate, the carrier plate rotates around the inner wall of the mounting plate under the drive of the control frame, thereby driving the focusing assembly on the carrier plate to rotate, realizing fine adjustment of the laser focusing direction. During the adjustment process, the washer prevents the control frame from directly colliding with the bracket, and the spring always generates a reverse pulling force on the control frame to ensure that the telescopic rod moves the locking rod stably without jamming. At the same time, after the adjustment is completed, the locking rod is kept in contact with the limiting hole to prevent the angle from shifting due to vibration.
[0009] Furthermore, a panel is installed on one side of the housing, and a window is installed on the inner wall of the panel to ensure stable use of the focusing component.
[0010] Furthermore, the inner wall of the housing is equipped with mounting bolts, one end of which is threaded into the panel for positioning the housing. The components adopt a modular design, which effectively reduces production costs and facilitates widespread use.
[0011] Furthermore, a control board is fixedly connected to the inner wall of the housing, and an interface is fixedly connected to the surface of the housing. The interface is electrically connected to the control board, and the control board is electrically connected to the telescopic rod via wires. The control board is also electrically connected to the focusing component via wires. When the focusing component is working, the laser beam is processed by it to form a positioning beam, which is emitted through the window on the inner wall of the panel to achieve precise positioning. The housing and the panel are fixed by mounting bolts to ensure the sealing and stability of the internal components. The control board is electrically connected to the telescopic rod and the focusing component via wires to uniformly receive and transmit control signals, ensuring that all components work together. The overall device has a compact structure and high integration. Through a dual angle adjustment method of coarse adjustment and fine adjustment, it can meet the high-precision laser positioning requirements in different scenarios. Moreover, it is simple to operate and can complete angle adjustment and fixation without complicated tools.
[0012] Furthermore, a positioning component is provided on the side of the housing away from the panel. The positioning component includes a positioning frame located on one side of the housing. An assembly bolt is threaded onto the inner wall of the housing, and one end of the assembly bolt is threaded into the positioning frame. A carrier is placed on the inner wall of the positioning frame. A positioning bolt is installed at the axis of the positioning frame and the carrier to guide the rotation of the positioning frame. The positioning component is designed with an arc-shaped guide hole that is collinear with the center of the positioning bolt, allowing the housing to be flexibly rotated around the positioning bolt to complete the overall angle coarse adjustment and quickly adapt to the basic positioning requirements of different installation scenarios.
[0013] Furthermore, the surface of the carrier is provided with guide holes, and the inner wall of the positioning frame is threaded with locking bolts. The locking bolts pass through the guide holes, and the carrier can be directly fixed to the external support. The arc-shaped guide hole design of the positioning component gives the housing a multi-angle rotation space, which can flexibly adapt to the angle requirements of different mounting surfaces without the need for complex modifications to the external support.
[0014] Furthermore, the nut of the locking bolt is larger than the guide hole, the guide hole is arc-shaped, and the center of the guide hole is on the same straight line as the positioning bolt. The device has a compact overall structure and high integration, integrating core components such as adjustment components and focusing components into the housing, occupying little space, and can be installed on various carriers such as vehicles, robotic arms, and testing equipment, greatly improving the adaptability of the device in different application scenarios.
[0015] In summary, the technical effects and advantages of this invention are as follows: 1. In this invention, the adjustment component interfaces with an external control signal through a control board, and can achieve automated fine-tuning through a telescopic rod. The operation is efficient and precise. At the same time, the washer can prevent direct collision between the control frame and the card holder during the adjustment process, and the spring always provides a reverse tension, which not only ensures that there is no jamming when the telescopic rod is driven, but also prevents the angle from shifting due to vibration after adjustment. Combined with the fastening of the housing and the panel by the mounting bolts, the overall stability of the device operation is further guaranteed.
[0016] 2. In this invention, the positioning component, through the design of the arc-shaped guide hole and the center of the positioning bolt being collinear, can flexibly rotate the housing around the positioning bolt to complete the overall angle coarse adjustment, quickly adapting to the basic positioning requirements of different installation scenarios. The adjustment component, with the help of the telescopic rod, pushes the clamp rod to move along the limiting hole, and through the control frame, drives the carrier plate and focusing component to rotate precisely, realizing the fine adjustment of the laser focusing direction, effectively making up for the deficiency of insufficient precision of single adjustment. Combined with the spring's contact and limiting effect on the clamp rod, it can significantly improve the angle accuracy and precision of laser positioning, meeting the high-precision positioning requirements in multiple scenarios such as vehicle and industrial applications.
[0017] 3. In this invention, the carrier can be directly fixed on the external support. The arc-shaped guide hole design of the positioning component gives the housing a multi-angle rotation space, which can flexibly adapt to the angle requirements of different mounting surfaces. There is no need to make complex modifications to the external support. The overall structure of the device is compact and highly integrated. The core components such as the adjustment component and the focusing component are integrated into the housing, occupying little space. It can be installed on various carriers such as vehicles, robotic arms, and testing equipment, which greatly improves the adaptability of the device in different application scenarios.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] refer to Figures 1-5The laser positioning device shown includes a housing 1. A mounting plate 6 is fixedly connected to the inner wall of the housing 1. A carrier plate 7 is rotatably connected to the inner wall of the mounting plate 6. A focusing assembly 10 is mounted on the carrier plate 7. An adjustment assembly 8 is provided on the carrier plate 7. The adjustment assembly 8 includes a control frame 81, which is fixedly connected to one side of the carrier plate 7. A telescopic rod 82 is fixedly connected to one side of the control frame 81, with the driving end of the telescopic rod 82 penetrating through the control frame 81. A clamping bracket 83 is fixedly connected to the side of the mounting plate 6 near the control frame 81. A limit hole 85 is formed in the inner wall of the clamping bracket 83. The driving end of the telescopic rod 82 extends to... In the bracket 83, a locking rod 84 is fixedly connected to the surface of the telescopic rod 82. The locking rod 84 is located in the limiting hole 85. The adjustment component 8 interfaces with the external control signal through the control board 9. Automatic fine-tuning can be achieved through the telescopic rod 82. The operation is efficient and precise. At the same time, the washer 87 can prevent direct collision between the control frame 81 and the bracket 83 during the adjustment process. The spring 86 always provides a reverse tension, which not only ensures that the telescopic rod 82 is driven without jamming, but also prevents the angle from shifting due to vibration after adjustment. Together with the mounting bolts 11 to fasten the housing 1 and the panel 4, the overall stability of the device operation is further guaranteed.
[0023] Among them, a washer 87 is fixedly connected to the side of the control frame 81 near the card holder 83, and the drive end of the telescopic rod 82 passes through the washer 87. The adjustment component 8 pushes the card rod 84 to move along the limiting hole 85 with the help of the telescopic rod 82. The control frame 81 drives the carrier plate 7 and the focusing component 10 to rotate precisely, so as to achieve fine adjustment of the laser focusing direction.
[0024] Among them, the side of the washer 87 away from the control frame 81 is fixedly connected to the spring 86, and the end of the spring 86 away from the washer 87 is fixedly connected to the surface of the card holder 83. This effectively makes up for the deficiency of insufficient single adjustment accuracy. Combined with the fitting and limiting effect of the spring 86 on the card rod 84, it can significantly improve the angle accuracy and precision of laser positioning, and meet the high-precision positioning needs in multiple scenarios such as vehicle and industry.
[0025] The control frame 81 has an "L"-shaped longitudinal section. The drive end of the telescopic rod 82 pushes the locking rod 84, which in turn drives the carrier plate 7 and the focusing assembly 10 to rotate. The focusing assembly 10 is finely adjusted by the adjusting assembly 8. The control plate 9 receives an external control signal through the interface 3 to start the telescopic rod 82. The drive end of the telescopic rod 82 pushes the locking rod 84 to move along the limiting hole 85 on the inner wall of the bracket 83, while simultaneously driving the "L"-shaped control frame 81 to move synchronously. Since the control frame 81 is fixedly connected to the carrier plate 7, the carrier plate 7 rotates around the inner wall of the mounting plate 6 under the drive of the control frame 81, which in turn drives the focusing assembly 10 on the carrier plate 7 to rotate, thus achieving fine adjustment of the laser focusing direction. During the adjustment process, the washer 87 prevents the control frame 81 from directly colliding with the bracket 83, and the spring 86 always generates a reverse pulling force on the control frame 81 to ensure that the telescopic rod 82 moves the locking rod 84 stably without jamming. At the same time, after the adjustment is completed, the locking rod 84 is kept in contact with the limiting hole 85 to prevent the angle from shifting due to vibration.
[0026] The housing 1 has a panel 4 installed on one side, and a window 5 is installed on the inner wall of the panel 4 to ensure the stable use of the focusing component 10.
[0027] The inner wall of the housing 1 is equipped with mounting bolts 11. One end of the mounting bolts 11 is threaded into the panel 4 for positioning the housing 1. The components adopt a modular design, which effectively reduces production costs and facilitates widespread use.
[0028] The inner wall of the housing 1 is fixedly connected to a control board 9, and the surface of the housing 1 is fixedly connected to an interface 3. The interface 3 is electrically connected to the control board 9. The control board 9 is electrically connected to the telescopic rod 82 via a wire, and the control board 9 is electrically connected to the focusing component 10 via a wire. When the focusing component 10 is working, the laser is processed by it to form a positioning beam, which is emitted through the window 5 on the inner wall of the panel 4 to achieve precise positioning. The housing 1 and the panel 4 are fixed by mounting bolts 11 to ensure the sealing and stability of the internal components. The control board 9 is electrically connected to the telescopic rod 82 and the focusing component 10 via wires to receive and transmit control signals in a unified manner, ensuring that all components work together. The overall device has a compact structure and high integration. Through the dual angle adjustment method of coarse adjustment and fine adjustment, it can meet the high-precision laser positioning requirements in different scenarios. Moreover, it is easy to operate and can complete the angle adjustment and fixation without complicated tools.
[0029] The housing 1 has a positioning component 2 on the side away from the panel 4. The positioning component 2 includes a positioning frame 25, which is located on one side of the housing 1. An assembly bolt 26 is threaded on the inner wall of the housing 1. One end of the assembly bolt 26 is threaded into the positioning frame 25. A carrier 21 is placed on the inner wall of the positioning frame 25. A positioning bolt 22 is installed at the axis of the positioning frame 25 and the carrier 21 to guide the rotation of the positioning frame 25. The positioning component 2 is designed with the arc-shaped guide hole 24 and the center of the positioning bolt 22 collinear, so that the housing 1 can be flexibly rotated around the positioning bolt 22 to complete the overall angle coarse adjustment and quickly adapt to the basic positioning requirements of different installation scenarios.
[0030] The carrier 21 has a guide hole 24 on its surface, and the inner wall of the positioning frame 25 is threaded with a locking bolt 23. The locking bolt 23 passes through the guide hole 24, and the carrier 21 can be directly fixed on the external support. The arc-shaped guide hole 24 of the positioning component 2 gives the housing 1 a multi-angle rotation space, which can flexibly adapt to the angle requirements of different mounting surfaces without the need for complex modifications to the external support.
[0031] Among them, the nut of the locking bolt 23 is larger than that of the guide hole 24. The guide hole 24 is arc-shaped, and the center of the guide hole 24 is on the same straight line as the positioning bolt 22. The device has a compact overall structure and high integration. It integrates core components such as the adjustment component 8 and the focusing component 10 into the housing 1, which occupies little space and can be installed on various carriers such as vehicles, robotic arms, and testing equipment, greatly improving the adaptability of the device in different application scenarios.
[0032] Working principle of the invention: Before use, the device is first installed and the angle is roughly adjusted by positioning component 2. The carrier 21 is fixed on the external support. Loosen the locking bolt 23 on the inner wall of the positioning frame 25. Since the guide hole 24 is arc-shaped and its center is collinear with the positioning bolt 22, the housing 1 can be rotated around the positioning bolt 22, which drives the positioning frame 25 to move synchronously along the guide hole 24 until the housing 1 is adjusted to the target coarse adjustment angle. After the angle is determined, tighten the locking bolt 23. Using the fact that the nut of the locking bolt 23 is larger than the specification of the guide hole 24, the positioning frame 25 and the carrier 21 are fixed, and the overall angle positioning of the device is completed, which can adapt to the basic positioning requirements of different installation scenarios. Subsequently, the focusing component 10 is finely angled by adjusting component 8. Control board 9 receives external control signals through interface 3 to start telescopic rod 82. The drive end of telescopic rod 82 pushes clamp rod 84 to move along the limiting hole 85 on the inner wall of clamp bracket 83, and at the same time drives "L"-shaped control frame 81 to move synchronously. Since control frame 81 is fixedly connected to carrier plate 7, carrier plate 7 rotates around the inner wall of mounting plate 6 under the drive of control frame 81, thereby driving focusing component 10 on carrier plate 7 to rotate, realizing fine adjustment of laser focusing direction. During the adjustment process, washer 87 prevents control frame 81 from colliding directly with clamp bracket 83, and spring 86 always generates reverse tension on control frame 81 to ensure that telescopic rod 82 moves clamp rod 84 stably without jamming. At the same time, after the adjustment is completed, clamp rod 84 is kept in contact with limiting hole 85 to prevent angle deviation due to vibration. When the focusing component 10 is working, the laser is processed by it to form a positioning beam, which is emitted through the window 5 on the inner wall of the panel 4 to achieve precise positioning. The housing 1 and the panel 4 are fixed by mounting bolts 11 to ensure the sealing and stability of the internal components. The control board 9 is electrically connected to the telescopic rod 82 and the focusing component 10 through wires to receive and transmit control signals in a unified manner to ensure that all components work together. The overall device has a compact structure and high integration. Through the dual angle adjustment method of coarse adjustment and fine adjustment, it can meet the high-precision laser positioning requirements in different scenarios. Moreover, it is easy to operate and can complete the angle adjustment and fixation without complicated tools.
