Description

Technical Field

[0001] This invention relates to the field of optical testing technology, and in particular to a target self-switching and self-rotation adjustment device. Background Technology

[0002] In the field of optical testing technology, especially in optical target simulation systems, targets are widely used. A target is a circular or square glass or metal plate with a specific perforation shape. A light beam can pass through the perforated area, thus forming an image of various simulated targets. Specific perforation shapes include circular holes, semi-circular holes, and checkered stripes. To improve the versatility of testing equipment and its applicability to different tested objects and parameters, targets need to be switched during different tests to form different simulated targets. Furthermore, for non-centrosymmetric targets, such as semi-circular targets and checkered stripe targets, their rotation angle also needs to be adjusted.

[0003] Existing technology integrates target switching and target angle rotation into a single mechanism, embedding the target angle adjustment mechanism within the target switching mechanism. When the target is switched, the target angle adjustment mechanism rotates accordingly, leading to problems such as wire winding. Using conductive slip rings to solve the wire winding problem would significantly increase structural complexity, cost, and subsequent maintenance work. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies that use a single mechanism to achieve target switching and target angle rotation, resulting in complex structure, high cost, and a significant increase in maintenance work. This invention proposes a target self-switching and self-rotation adjustment device that allows the target switching mechanism and the target angle adjustment mechanism to be arranged in layers, enabling independent control of the two mechanisms and allowing the target switching function and the target angle adjustment function to be implemented independently without being affected.

[0005] To achieve the above objectives, the present invention adopts the following specific technical solution:

[0006] The target self-switching and self-rotation adjustment device provided by the present invention includes a housing base, a target switching mechanism, and a target angle adjustment mechanism; wherein...

[0007] A first mounting hole, a second mounting hole, and a light-transmitting port are provided on the outer casing base;

[0008] The target switching mechanism includes a target switching motor, a target switching drive gear, a target switching driven gear, and a switching collar. The target switching motor is mounted on the housing base through the second mounting hole. The target switching drive gear is mounted on the output shaft of the target switching motor. The target switching driven gear is mounted on the housing base through the switching collar. The meshing of the target switching drive gear and the target switching driven gear allows different targets to be switched to the light transmission port, realizing the self-switching function of the target.

[0009] The target angle adjustment mechanism includes an angle adjustment motor, an angle adjustment coupling, an angle adjustment drive shaft, an angle adjustment collar, an angle adjustment drive gear, an angle adjustment driven gear, and angular contact ball bearings. The angle adjustment drive gear is mounted on the target switching driven gear through the angle adjustment collar. The angle adjustment drive shaft passes through the first mounting hole and is mounted on the angle adjustment drive gear. The angle adjustment coupling connects the output shaft of the angle adjustment motor to the angle adjustment drive shaft. The entire assembly consisting of the angle adjustment motor, angle adjustment coupling, and angle adjustment drive shaft is mounted on the housing base through the first mounting hole. The angle adjustment driven gears are evenly mounted on the target switching driven gears through angular contact ball bearings. The target is mounted on each angle adjustment driven gear. The self-rotation adjustment function of the target is realized through the meshing of the angle adjustment drive gear and the angle adjustment driven gear.

[0010] Preferably, a first photoelectric switch and a second photoelectric switch are installed on the housing base, and a baffle and a stud are installed on the target switching driven gear. The first photoelectric switch is triggered by the baffle to realize the target self-switching reset function; the second photoelectric switch is triggered by the stud to realize the target self-switching counting function, so that the light port corresponds to the required target.

[0011] Preferably, both the target switching motor and the angle adjustment motor are stepper motors.

[0012] The present invention can achieve the following technical effects:

[0013] 1. This invention enables the target switching mechanism and the target angle adjustment mechanism to be arranged in layers, achieving independent control of the two mechanisms, so that the target switching function and the target angle adjustment function can be realized independently without being affected.

[0014] 2. In the connection between the target switching mechanism and the target angle adjustment mechanism, the present invention uses a collar and an angular contact ball. Through the relative rotation of the inner and outer rings of the bearing, the target switching and target angle adjustment functions are made independent of each other, avoiding the problem of wire winding and saving costs.

[0023] In the following description, embodiments of the invention will be described with reference to the accompanying drawings. In the description below, the same modules are denoted by the same reference numerals. Where the same reference numerals are used, their names and functions are also the same. Therefore, their detailed description will not be repeated.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not constitute a limitation thereof.

[0025] Figure 1 A cross-sectional view of a target self-switching and self-rotation adjustment device according to an embodiment of the present invention is shown. Figure 2 and Figure 3 The upper and middle portions of the cross-sectional view of the target self-switching and self-rotation adjustment device provided in one embodiment of the present invention have been supplemented respectively. Figure 4 and Figure 5The structure of the target self-switching and self-rotation adjustment device is shown from two different perspectives. Figure 6 and Figure 7 The three-view diagrams of the target self-switching and self-rotation adjustment device are shown from two different perspectives.

[0026] like Figures 1-5 As shown, the target self-switching and self-rotation adjustment device provided by the present invention includes a housing base, a target switching mechanism, and a target angle adjustment mechanism. The housing base 4 serves as the foundation of the overall mechanism, and all components are mounted and fixed on it. The target switching mechanism is used for target self-switching, and the target angle adjustment mechanism is used to realize automatic adjustment of the target angle.

[0027] To clearly describe the target self-switching and self-rotation adjustment device provided by the present invention, the device is divided into three parts: the outer shell base, the target switching mechanism, and the target angle adjustment mechanism, which will be described in detail.

[0028] The outer casing base 4 has a first mounting hole, a second mounting hole, and a light-transmitting port 17. The first mounting hole is used to fix the whole consisting of the angle adjustment motor 1, the angle adjustment coupling 2, and the angle adjustment transmission shaft 3. The angle adjustment transmission shaft 3 passes through the first mounting hole and is assembled with the angle adjustment drive gear 6. The second mounting hole is used to fix the target switching motor 16, and the output shaft of the target switching motor 16 passes through the first mounting hole and is assembled with the target switching drive gear 15.

[0029] The target switching mechanism includes a target switching motor 16, a target switching drive gear 15, a target switching driven gear 9, and a switching collar 8. The target switching motor 16 is a stepper motor with a reducer. The reducer improves the motion resolution, makes the rotation smoother, and reduces noise. After the target switching drive gear 15 is mounted on the output shaft of the target switching motor 16, the target switching driven gear 9 is mounted on the housing base 4 using the switching collar 8. The switching collar 8 is a crossed roller bearing with rollers between the inner and outer rings, and mounting holes on the inner and outer rings. The inner and outer rings can be directly fixed to other components, saving installation space and avoiding the problem of wire winding. The target switching driven gear 9 is equipped with studs 11 and baffles. The number of studs 11 corresponds to the number of targets. When the target switching motor 16 starts, it drives the target switching drive gear 15 to rotate. The meshing of the target switching drive gear 15 and the target switching driven gear 9 causes the targets to revolve, switching different targets to the light-transmitting port 17. Simultaneously, the baffles and studs 11 on the target switching driven gear 9 rotate. If the baffle triggers the first photoelectric switch 10, the target is switched... The switching mechanism stops rotating and uses this as the zero point to switch targets. At this time, the target displayed on the light port 17 is target number 1. If you want to switch to target number 2, control the target switching driven gear 9 to rotate, so that the stud 11 triggers the second photoelectric switch 12 once, that is, switch to target number 2. If you want to switch to target number 3 13, make the stud 11 trigger the second photoelectric switch 12 twice, that is, switch to target number 3 13. And so on, so that the desired target number 13 can be switched to the light port 17, thereby realizing the self-switching function of the target.

[0030] The target angle adjustment mechanism includes an angle adjustment motor 1, an angle adjustment coupling 2, an angle adjustment drive shaft 3, an angle adjustment collar 7, an angle adjustment drive gear 6, an angle adjustment driven gear 5, and an angular contact ball bearing 14. To prevent jamming during rotation, the angle adjustment motor 1 is connected to the angle adjustment drive shaft 3 via the angle adjustment coupling 2, transmitting power to the angle adjustment drive gear 6. After assembling the angle adjustment drive gear 6 with the angle adjustment motor 1, the angle adjustment drive gear 6 is mounted on the target switching driven gear 9 using the angle adjustment collar 7. The angle adjustment driven gears 5 are evenly distributed and mounted on the target switching driven gear 9 via the angular contact ball bearings 14. The connection via the angular contact ball bearings 14 ensures that the rotation of the angle adjustment driven gears 5 does not affect the target switching driven gear 9. The target is mounted on each angle adjustment driven gear 5, and the angle adjustment motor 1 drives the angle adjustment drive gear 6 to rotate. The meshing of the angle adjustment drive gear 6 and the angle adjustment driven gear 5 causes the target to rotate, achieving the target's self-rotation adjustment function.
