Description

Technical Field

[0001] This invention relates to the field of precision measurement technology, and more particularly to a precision mechanism alignment device. Background Technology

[0002] In existing technologies, precision alignment devices typically use fixed adjustment methods, such as bolts and screws. However, this method has the following problems: Insufficient precision: Due to the manufacturing precision and processing errors of bolts or screws, the adjustment precision is limited, making it difficult to meet high-precision requirements. Inconvenient adjustment: Adjusting bolts or screws requires manual rotation, which is cumbersome, inconvenient for rapid adjustment, and difficult to control the adjustment amount, easily leading to errors. Precision affected by external forces: In actual use, external environmental factors and operator errors can affect the adjustment of bolts or screws, resulting in a decrease in alignment precision.

[0003] Therefore, a precision alignment device is urgently needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a precision mechanism alignment device that can improve the safety and reliability of alignment operations, increase alignment accuracy, and reduce errors.

[0005] To achieve this objective, the present invention employs the following solution:

[0006] A precision alignment device includes a frame, an upper alignment mechanism, a lower alignment mechanism, and a coarse alignment mechanism. The lower alignment mechanism includes a first bracket, a roller assembly, and a micrometer adjustment assembly. The first bracket is mounted on the frame, and the micrometer adjustment assembly is mounted on the first bracket and connected to the roller assembly. The micrometer adjustment assembly is configured to adjust the level of the roller assembly in the height direction. The upper alignment mechanism includes a second bracket, a vision assembly, and a leveling bolt. The second bracket is slidably mounted on the frame in the height direction, and the vision assembly is mounted on the second bracket and configured to detect the horizontal angle of the second bracket. The leveling bolt is mounted at the bottom of the second bracket. The coarse alignment mechanism is mounted at the top of the first bracket, and the leveling bolt can abut against the coarse alignment mechanism.

[0007] For example, the roller assembly includes a base plate, a first drive member, and a roller. The base plate is connected to the first bracket, the first drive member is mounted on the base plate, and the output end of the first drive member is connected to the roller. The first drive member is configured to drive the roller to move in the height direction. An adjustment assembly is mounted on the base plate, and the output end of the micrometer adjustment assembly abuts against the bottom of the first bracket. The micrometer adjustment assembly is configured to adjust whether the base plate is level.

[0008] For example, the first driving component is a cylinder.

[0009] For example, the lower alignment mechanism is slidably mounted on the frame.

[0010] For example, the lower alignment mechanism further includes a first sliding component, which is horizontally mounted on the frame, and the first bracket is slidably connected to the first sliding component.

[0011] For example, the first sliding component is a guide rail slider module.

[0012] For example, the upper alignment mechanism further includes a second sliding component, which is mounted on the frame along the height direction, and the second bracket is slidably connected to the frame through the second sliding component.

[0013] For example, the second sliding component is a guide rail slider module.

[0014] For example, the leveling bolts are provided in four sets, and the four sets of leveling bolts are distributed at intervals at the bottom of the second bracket.

[0015] For example, the vision component includes a camera bracket, a CCD camera, and a light source. The camera bracket is connected to the second bracket, the CCD camera is mounted on the camera bracket, and the light source is mounted on the camera bracket and can provide light to the CCD camera.

[0016] The beneficial effects of this invention are as follows:

[0028] The precision alignment device in this embodiment includes a frame 100, an upper alignment mechanism 200, a lower alignment mechanism 300, and a coarse alignment mechanism 400, such as... Figures 1 to 4As shown, the lower alignment mechanism 300 includes a first bracket 310, a roller assembly 320, and a micrometer adjustment assembly 330. The first bracket 310 is mounted on the frame 100, and the micrometer adjustment assembly 330 is mounted on the first bracket 310. The micrometer adjustment assembly 330 is connected to the roller assembly 320 and is configured to adjust the horizontal position of the roller assembly 320 in the height direction. The upper alignment mechanism 200 includes a second bracket 210, a vision assembly 220, and a leveling bolt 230. The second bracket 210 is slidably mounted on the frame 100 in the height direction. The vision assembly 220 is mounted on the second bracket 210 and is configured to detect the horizontal angle of the second bracket 210. The leveling bolt 230 is mounted on the bottom of the second bracket 210. The coarse alignment mechanism 400 is mounted on the top of the first bracket 310, and the leveling bolt 230 can abut against the coarse alignment mechanism 400. In this embodiment, the upper alignment mechanism 200 and the lower alignment mechanism 300 in the precision alignment device are first positioned using the coarse alignment mechanism 400, and then leveled using the vision mechanism for horizontal angle detection and the leveling bolt 230, achieving high-precision alignment adjustment, reducing the impact of angle deviation, and avoiding the errors of traditional adjustment methods. Then, the position of the roller assembly 320 is adjusted using the micrometer adjustment component 330, which can achieve precise adjustment and reduce errors, thereby achieving accurate alignment and convenient operation.

[0029] Furthermore, the roller assembly 320 in this embodiment includes a base plate 321, a first driving member 322, and a roller 323. The base plate 321 is connected to the first support 310. The first driving member 322 is mounted on the base plate 321, and its output end is connected to the roller 323. The first driving member 322 is configured to drive the roller 323 to move in the height direction. A micrometer adjustment assembly 330 is mounted on the base plate 321, and its output end abuts against the bottom of the first support 310. The micrometer adjustment assembly 330 is configured to adjust whether the base plate 321 is level. Through the design of the roller assembly 320, the displacement of the roller 323 in the height direction can be driven and precisely adjusted. At the same time, the configuration of the micrometer adjustment assembly 330 can ensure the levelness of the base plate 321, thereby ensuring the accuracy and precision of the alignment device in terms of horizontal angle. Furthermore, due to the simple structure of the roller assembly 320, it is easy to adjust and maintain, which can improve the operating efficiency and service life of the entire precision mechanism alignment device.

[0030] Specifically, in this embodiment, the first driving component 322 is a cylinder. The roller assembly 320 uses a cylinder as the first driving component 322. Compared with traditional transmission methods such as motors, the cylinder drive is more precise and stable, and can avoid errors caused by motor vibration, thereby improving the accuracy and stability of the device.

[0031] Furthermore, in this embodiment, the lower alignment mechanism 300 is slidably mounted on the frame 100. The lower alignment mechanism 300 can be slidably mounted on the frame 100, and the feeding position of the lower alignment mechanism 300 can be adjusted. The position of the lower alignment mechanism 300 can be precisely adjusted according to specific needs, so as to achieve more accurate alignment, thereby improving alignment accuracy and stability.

[0032] Preferably, the lower alignment mechanism 300 in this embodiment further includes a first sliding component 340, which is horizontally mounted on the frame 100, and the first support 310 is slidably connected to the first sliding component 340. The first sliding component 340, being horizontally mounted on the frame 100 and slidably connected to the first support 310, allows for fine-tuning of the lower alignment mechanism 300 in the horizontal direction. The first support 310 of the lower alignment mechanism 300 can be adjusted in position by sliding the first sliding component 340, thereby enabling fine-tuning of the horizontal position of the roller assembly 320, thus improving positional accuracy.

[0033] Specifically, in this embodiment, the first sliding component 340 is a guide rail slider module. The guide rail slider module is a traditional mechanical transmission component with advantages such as high precision, good rigidity, and smooth movement. The guide rail slider module allows the first support 310 to slide horizontally along it, thereby adjusting the feeding position of the lower alignment mechanism 300. The guide rail slider module has good precision and stability, thus effectively improving the alignment accuracy and adjustability of the precision mechanism alignment device.

[0034] Furthermore, the upper alignment mechanism 200 in this embodiment also includes a second sliding component 240, which is mounted on the frame 100 along the height direction. The second support 210 is slidably connected to the frame 100 via the second sliding component 240. The second sliding component 240 being mounted on the frame 100 along the height direction and slidably connecting the frame 100 and the second support 210 allows for precise adjustment of the entire upper alignment mechanism 200 in the height direction, improving positioning accuracy and stability. Since the second support 210 is slidably connected to the frame 100 via the second sliding component 240, its position can be finely adjusted along the height direction during position adjustment, achieving a more precise adjustment effect.

[0035] Specifically, in this embodiment, the second sliding component 240 is a guide rail slider module to further improve the accuracy and stability of the upper alignment mechanism 200, ensuring that no deviation or vibration occurs during vertical movement. The guide rail slider module is a mechanical component specifically designed for precision positioning systems, featuring high precision, high rigidity, and low friction. Therefore, using a guide rail slider module as the second sliding component 240 can effectively improve the working efficiency and accuracy of the precision mechanism alignment device, thereby meeting the requirements of high-precision machining for positioning accuracy and stability.

[0036] Preferably, in this embodiment, four sets of leveling bolts 230 are provided, which are spaced apart at the bottom of the second bracket 210. This allows for fine-tuning and balancing of the second bracket 210 in the horizontal direction by adjusting the tightness of the leveling bolts 230, thereby ensuring greater stability and reliability of the entire device during use and improving alignment accuracy and stability. The distribution of the four sets of leveling bolts 230 can balance the bearing pressure, reduce alignment errors, and improve accuracy.

[0037] Specifically, the vision component 220 in this embodiment includes a camera bracket 221, a CCD camera 222, and a light source 223. The camera bracket 221 is connected to the second bracket 210. The CCD camera 222 is mounted on the camera bracket 221, and the light source 223 is also mounted on the camera bracket 221. The light source 223 provides light to the CCD camera 222, enabling high-precision visual-assisted positioning. The connection between the camera bracket 221 and the second bracket 210 ensures the stability and accuracy of the camera position, allowing the CCD camera 222 to provide high-quality images during precision mechanism alignment. The light source 223 provides sufficient light to the camera, ensuring image brightness and clarity. Therefore, the precision mechanism alignment device can improve work efficiency and accuracy during operation and reduce the error rate.
