[0031] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0032] In the description of this utility model, the terms "part", "side", "end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] like Figure 1 As shown, this application provides a universal lens shooting fixture, including a base 1 and a fixed seat 2 fixed to the base 1. The base 1 is provided with a slide rail 11 for guiding sliding, and a sliding seat 3 is slidably disposed on the slide rail 11. An industrial camera 7 is fixed on the fixed seat 2, and a clamp 4 for holding the lens 8 is fixed on the sliding seat 3. The sliding seat 3 is controlled by a lead screw 12, which allows the lens 8 to move closer to or further away from the industrial camera 7 on the slide rail 11, so as to adjust according to different focal length requirements. By fixing the industrial camera 7 to the fixed seat 2, the stability of the camera position can be ensured, avoiding positioning errors caused by the simultaneous movement of the camera and lens 8, and improving the overall shooting accuracy and efficiency.

[0034] Specifically, the base 1 is a rectangular base made of stainless steel, aluminum alloy, or other metal materials, possessing high rigidity and corrosion resistance, allowing for long-term use in various industrial environments with good stability. A support block 13 is fixed at each end of the base 1, and the aforementioned slide rail 11 is mounted between the two support blocks 13. At least one lead screw 12 is rotatably mounted on the slide 3, which is threadedly connected to the lead screw 12, ensuring the smooth movement of the slide 3 and achieving precise positioning through the lead screw 12 transmission.

[0035] like Figure 1 In the specific embodiment shown, two cylindrical slide rails 11 are parallel to each other between the two support blocks 13. The double slide rails 11 reduce the sway of the sliding seat 3 during movement, maintain high-precision linear motion, and reduce focusing errors between the lens 8 and the industrial camera 7. A lead screw 12 is rotatably connected between the two slide rails 11. One end of the lead screw 12 extends to the outside of a support block 13, forming a knob. Rotating the knob controls the rotation of the lead screw 12, thereby controlling the movement of the moving stage back and forth on the slide rails 11. The structure is simple, easy to adjust, and can meet the general shooting needs of different focal lengths and measured parts sizes. The above structure can be widely used in situations where different lenses or workpieces need to be replaced. By controlling the rotation of the lead screw 12 through the knob, the distance between the lens 8 and the industrial camera 7 can be adjusted, reducing repetitive disassembly and assembly processes and improving work efficiency.

[0036] Furthermore, the support block 13 is provided with a threaded hole that passes through the base 1, so that the fixture can be fixed on the workbench by bolts, thereby improving the connection strength between the fixture and the workbench and the overall stability during operation.

[0037] like Figure 1 and Figure 2 As shown, the fixing base 2 is rectangular in shape and is fixedly connected to the base 1 by bolts, glue, or other methods, such as... Figure 1 In the embodiment shown, the fixing base 2 is positioned between two support blocks 13 and is close to one of the support blocks 13. Three through holes are provided at the lower position, through which two slide rails 11 and a lead screw 12 pass, thereby enhancing the overall stability between the fixing base 2 and the base 1, resulting in a more compact structure. Figure 2 As shown, the industrial camera 7 is mounted on top of the mounting base 2, ensuring that the required optical center of the camera remains constant. Only the lens 8 is moved to adjust the focal length, reducing complexity and ensuring consistent imaging. A clamp 4 is fixed on the sliding block, which holds the lens 8. By rotating the knob, the position of the sliding block is adjusted, moving the lens 8 to a distance that matches the focal length of the industrial camera 7, thus achieving focus.

[0038] Furthermore, such as Figure 1 and Figure 2 As shown, the sliding base 3 is equipped with an adjustment platform for adjusting and aligning the optical axes of the industrial camera 7 and the lens 8.

[0039] Specifically, the adjustment platform is a three-axis moving platform, including three adjusting screws 51, which are used for horizontal adjustment, vertical adjustment and height adjustment respectively. By rotating these three adjusting screws 51, the optical axis of the industrial camera 7 and the lens 8 can be more precisely aligned to obtain better shooting results. At the same time, the three-axis moving platform can perform precise position adjustment within a small range, which can meet higher precision requirements in different application scenarios and has strong versatility.

[0040] like Figure 1 and Figure 2 The specific embodiment shown also includes an adapter 6, which includes a first connecting plate 61 and a second connecting plate 62 arranged perpendicularly to each other; wherein, the first connecting plate 61 is fixed to the upper end surface of the adjustment platform, and the first connecting plate 61 and the second connecting plate 62 are at a 90° angle. Figure 2 As shown, the lens 8 held by the clamp 4 can be directly facing the industrial camera 7. Furthermore, the second connecting plate 62 has a first hollow part 621 in the middle, and a plurality of connecting grooves 622 are arranged around the first hollow part 621. The clamp 4 is fixed on the second connecting plate 62 by connecting the even number of connecting grooves 622 with bolts or other fasteners.

[0041] In one specific embodiment, the clamp 4 is a three-jaw chuck, including a connecting seat 41. A second hollow part 411 is provided in the middle of the connecting seat 41. The second hollow part 411 and the first hollow part 621 form the shooting channel of the lens 8.

[0042] The three-jaw chuck is equipped with three jaw assemblies. By inserting a wrench into the square hole on the side wall of the connecting seat 41, the internal gear assembly (not shown in the figure) is driven to open or close the three jaw assemblies simultaneously. This will not be elaborated here, but it should be understood that the clamp 4 is not limited to a three-jaw chuck, but can also be a four-jaw chuck, a scroll chuck, or other clamping components.

[0043] like Figure 3 and Figure 4 As shown, in the above embodiment, the claw assembly includes a slider 42 and a locking block 43. The slider 42 is slidably disposed inside the groove 412 of the connecting seat 41 and is provided with a plurality of connecting parts 421. The locking block 43 is detachably fixed to the connecting parts 421 by fasteners. The locking block 43 adopts a detachable design. When the locking block 43 is worn due to long-term use, only the locking block 43 needs to be replaced to continue to be used. It is not necessary to replace the entire fixture 4 structure, which significantly reduces maintenance costs.

[0044] In one embodiment, the connecting part 421 is a bolt hole, and the locking block 43 is fixedly connected to the slider 42 by bolts.

[0045] like Figure 3 and Figure 4 The specific embodiment shown includes two bolt holes, and the locking block 43 is provided with corresponding holes. By fixing it to different connecting parts 421, the locking position adjustment is achieved. Specifically, as... Figure 3 As shown, the holes of the locking block 43 correspond one-to-one with the bolt holes, and the bolts are tightened to achieve detachable fixing; as shown Figure 4 As shown, the hole above the locking block 43 corresponds to the bolt hole below the slider 42, and is tightened by bolts to expand the clamping range, making it suitable for larger shooting lenses.

[0046] Furthermore, such as Figure 3 and Figure 4 As shown, a limiting groove 422 is provided between two adjacent connecting parts 421, and a limiting block 431 is provided between adjacent holes of the locking block 43. Figure 3 In the embodiment shown, the limiting block 431 is engaged with the limiting groove 422, as... Figure 4 In the embodiment shown, the lower edge of the slider 42 abuts against the upper edge of the limiting block 431, which facilitates positioning and prevents the clamping block 43 from shifting during use, thus preventing the clamping from becoming loose.

[0047] It should be understood that the connecting part 421 is not limited to two. When multiple connecting parts 421 are provided, attention should be paid to the fact that the multiple limiting grooves 422 are of the same size and are all located in the middle position of two adjacent connecting parts 421. Those skilled in the art should be able to understand and implement this in conjunction with the above embodiments.

[0048] In summary, the universal lens shooting fixture described in this application maintains a simple and compact structure and is easy to assemble. Through the cooperation of the base 1, slide rail 11, lead screw 12, sliding seat 3 and fixed seat 2, the distance between the lens 8 and the industrial camera 7 can be flexibly adjusted. With the help of the three-axis adjustment platform, adapter 6 and clamp 4, it can realize the assembly and shooting of various lenses such as zoom cameras, MFZ cameras or single-focus lenses, and has significant versatility.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
