[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 2As shown, this embodiment provides a bicycle head tube clamping and fixing device for laser equipment. The bicycle head tube clamping and fixing device for laser equipment includes: a support base 1, an adjusting base plate 2, a positioning plate 3, and a clamping assembly. The support base 1 has a guide rail 11, which extends along a first direction. The adjusting base plate 2 is slidably disposed on the guide rail 11. The positioning plate 3 is fixedly disposed on the support base 1. The clamping assembly includes a plurality of clamping members spaced apart along a second direction on the adjusting base plate 2. The clamping members slide through the adjusting base plate 2 along the first direction and can press the bicycle head tube between the clamping members and the positioning plate 3. The first direction and the second direction are perpendicular to each other. This setup allows for adaptive movement and adjustment of the base plate 2 along the first direction based on the specifications and model of the bicycle head tube. This enables the rapid clamping of the clamping components and positioning plate 3 onto the bicycle head tube, facilitating laser cutting. Only one device is needed to perform laser cutting of multiple models and specifications of bicycle head tubes, further reducing mold costs, minimizing mold space, saving mold changeover time, increasing mold changeover speed, and offering flexible and convenient operation with strong versatility, effectively improving the efficiency of bicycle head tube production. It should be noted that the first direction and the second direction are respectively... Figure 1 The arrow in the image indicates the direction.

[0035] Specifically, this embodiment provides the following technical solution by way of example: the adjusting base plate 2 includes a support part 21 and a sliding part 22, the support part 21 and the sliding part 22 are fixedly connected, the sliding part 22 is slidably disposed on the guide rail 11, a plurality of clamping members are spaced apart on the support part 21 along the second direction, and the clamping members slide through the support part 21 along the first direction.

[0036] Furthermore, in order to optimize space utilization and improve the rigidity of the structure, the base plate 2 is L-shaped, and the support part 21 protrudes from one end of the sliding part 22 along its length.

[0037] Optionally, the bicycle head tube clamping and fixing device for laser equipment further includes several fixing blocks 4, which are spaced apart on the positioning plate 3 along a second direction. The fixing blocks 4 and clamping members are arranged in a one-to-one correspondence along a first direction, with the bicycle head tube pressed between the fixing blocks 4 and the clamping members. This arrangement increases the number of clamping and fixing points for the bicycle head tube, further improving the precision and stability of production and processing, and ensuring the efficiency of laser cutting operations.

[0038] In this embodiment, the clamping component includes a pull rod 5, a pressure block 6, and a limiting block 7. The pressure block 6 is fixedly disposed at one end of the pull rod 5 along its own length direction. A plurality of fixing blocks 4 are correspondingly disposed with a plurality of pressure blocks 6 along a first direction. The bicycle head tube is pressed between the pressure block 6 and the fixing blocks 4. The limiting block 7 is fixedly disposed at the other end of the pull rod 5 along its own length direction. The support part 21 is located between the limiting block 7 and the pressure block 6. The limiting block 7 can abut against the support part 21 to restrict the movement of the pull rod 5 along the first direction. With this configuration, for bicycle head tubes of different specifications and models, the adjusting base plate 2 can be slid to a suitable position, and the pull rod 5 can be adaptively moved and adjusted to achieve clamping and fixing of the bicycle head tube by the pressure block 6 and the fixing blocks 4. At the same time, the limiting block 7 can further constrain and limit the pull rod 5 along the first direction to prevent the pull rod 5 from detaching from the support part 21. The overall operation is convenient, reliable, and highly practical.

[0039] Furthermore, the pressure block 6 is frustum-shaped and can undergo elastic deformation to mitigate the impact on the bicycle head tube and prevent damage to the bicycle head tube.

[0040] In this embodiment, there are three clamping components, which are spaced apart and evenly arranged. Of course, in other embodiments, the number and arrangement of the clamping components can be set according to actual needs, and no further restrictions are imposed here.

[0041] Optionally, in order to achieve dynamic pressure compensation and vibration absorption for the pressure block 6, the clamping assembly also includes several elastic elements 8, which are arranged one-to-one with several pull rods 5. The elastic elements 8 are sleeved on the pull rods 5, and one end of the elastic element 8 abuts against the support part 21, while the other end of the elastic element 8 abuts against the pressure block 6. Further, the elastic element 8 is a compression spring.

[0042] Optionally, to facilitate subsequent clamping and fixing of the bicycle head tube and achieve dynamic rigidity switching, the bicycle head tube clamping and fixing device for laser equipment also includes several locking components. These locking components can lock or unlock the relative position between the base plate 2 and the guide rail 11. Further, the locking components are bolts.
