[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please see Figures 1-2 The embodiments of this utility model include:

[0018] like Figure 1The positioning fixture shown is used for marking QR codes in the inner hole of the housing. It is used for tilting and fixing the housing 16. It includes: base 1, back plate 2, positioning plate 4, positioning seat 5, support rod 3, quick clamp 8 and pressure block 9. The back plate 2 is set on the base 1. The bottom of the back plate 2 can be welded to the base 1 or fixed by screws, and the structure is stable.

[0019] The positioning plate 4 is tilted and set on one side of the backing plate 2. The positioning plate 4 is provided with a first screw 12 that connects to the backing plate 2. The structure is sturdy and easy to disassemble and assemble. The housing 16 is placed vertically on the front of the positioning plate 4. In this embodiment, the backing plate 2 is provided with a slope 13 on the side facing the positioning plate 4. The positioning plate 4 is set on the slope 13. The slope 13 on the backing plate 2 is used to limit the angle of the positioning plate 4, so that the housing 16 is placed vertically on the positioning plate 4 while maintaining a predetermined tilt angle, exposing the inner hole QR code printing area 18. This allows the QR code printing device to extend from above and downward into the inner hole of the housing 16 to perform the QR code printing operation on the inner hole QR code printing area 18.

[0020] The rear end of the housing 16 is provided with a shaft hole, such as... Figure 2 As shown, the front of the positioning plate 4 is provided with a positioning pin 15 corresponding to the shaft hole. The tail end of the housing 16 is positioned by the positioning pin 15 to ensure concentricity.

[0021] Furthermore, the positioning seat 5 is positioned on the front of the positioning plate 4 and on both sides of the housing 16. Ear seats 17 are provided on both sides of the housing. The positioning seat 5 has recessed positioning grooves 6 corresponding to the ear seats 17. The ear seats 17 and the positioning grooves 6 cooperate to perform radial and circumferential positioning of the housing 16, achieving high precision and avoiding radial movement or torsion during the QR code printing process. The positioning seat 5 is equipped with a second screw 7 that connects to the positioning plate 4, resulting in a robust structure and convenient assembly / disassembly.

[0022] A mounting block 11 is provided on the front of the positioning plate 4, located on the side below the housing. A quick clamp 8 is mounted on the mounting block 11, and a pressure block 9 is mounted on the quick clamp 8 and extends to the front of the housing 16. The quick clamp 8 drives the pressure block 9 to press the front of the housing 16, improving clamping stability. The quick clamp 8 is easy to operate, facilitating the reset of the pressure block 9 and the disassembly of the housing 16, thus improving production efficiency.

[0023] The support rod 3 is mounted on the base 1, and its bottom can be threaded into the base 1, ensuring structural stability. The top of the support rod 3 extends to the bottom front end of the housing 16. In this embodiment, the QR code printing area 18 inside the housing 16 is located above the top of the support rod 3. Figure 1 As shown, the support rod 3 supports the bottom front end of the housing 16, improving stability during the QR code printing process.

[0024] like Figure 2As shown, a positioning post 10 is provided at the top of the support rod 3, and a positioning hole corresponding to the positioning post 10 is provided in the recessed front end of the bottom of the housing 16. Through the cooperation of the positioning post 10 and the positioning hole, the contact position accuracy and stability between the top of the support rod 3 and the front end of the bottom of the housing 16 are improved.

[0025] In addition, a limiting adjustment screw 14 is detachably provided on the front of the positioning plate 4, located on one side of the positioning pin 15. The positioning plate 4 is provided with a threaded hole corresponding to the limiting adjustment screw 14, which facilitates axial adjustment by rotating the limiting adjustment screw 14. The tail end of the housing 16 contacts the end of the limiting adjustment screw 14. By adjusting the axial direction of the limiting adjustment screw 14, the axial direction of the housing 16 is finely adjusted to ensure that the top of the support rod 3 contacts the bottom front end of the housing 16, and to ensure that the inner hole QR code printing area 18 is located directly below the QR code printing device.

[0026] In summary, the positioning fixture for printing QR codes in the inner hole of a machine casing as described in this utility model can position and clamp the machine casing, facilitate the operation of printing QR codes in the inner hole, and improve the stability during the process of printing QR codes in the inner hole of the machine casing.
