[0032] Cooperate Figures 1 to 6 As shown, this utility model discloses a frame fixing fixture and a laser engraving machine. The fixing fixture is used to fix the carbon fiber frame 10 on the laser engraving machine, and the carbon fiber frame 10 is laser engraved by the laser engraving machine, which replaces the existing manual sandpaper sanding, effectively improving efficiency and ensuring product quality.

[0033] Cooperate Figures 1 to 3 As shown, a vehicle frame fixing fixture includes:

[0034] The fixture body 20 has a T-shaped groove 21 on its upper surface that is adapted to accommodate the placement of the vehicle frame 10, and the T-shaped groove 21 is a through groove.

[0035] The fixture body 20 has a fixing groove 22 at its bottom end that engages with the fixing block 30, and the fixing block 30 has a fixing hole 31.

[0036] The frame has 10 fixing fixtures for securing such... Figure 1 The carbon fiber frame 10 shown is T-shaped. The shape and size of the T-shaped groove 21 are adapted to the frame 10, allowing the frame 10 to fit snugly into the T-shaped groove 21. Simultaneously, the glued portion 10 of the frame 10 faces upwards and is in a horizontal position. The T-shaped groove 21 is a through groove, meaning that all three ends of the T-shaped groove 21 are not closed. Correspondingly, the T-shaped groove 21 is designed to accommodate a portion of the frame 10. Thus, the overall volume of the fixture body 20 does not need to be too large, but due to the shape and fitting arrangement of the frame 10 and the T-shaped groove 21, the frame 10 is securely embedded in the T-shaped groove 21.

[0037] The fixing block 30 is used for fixing the jig body 20 in cooperation with the jig body 20, and specifically, the fixing block 30 is fixed by clamping the fixing groove 22 at the bottom end of the jig body 20, and the fixing hole 31 of the fixing block 30 is used for fixing the fixing block 30.

[0038] In the embodiment, the number of the T-shaped grooves 21 is two, and the two T-shaped grooves 21 are symmetrically arranged on the upper end surface of the jig body 20. On the one hand, the frame 10 has the adhesive parts 11 needing to be processed by laser engraving on both the front and back surfaces, and the two symmetrically arranged T-shaped grooves 21 correspond to the front surface of the frame 10. On the other hand, after the frame 10 in one of the T-shaped grooves 21 is processed, the worker can take it out from the T-shaped groove 21 and wipe off the surface dust, and at the same time, the laser head 51 can immediately process the frame 10 in the other T-shaped groove 21, so that the processing parts of the frame 10 are adapted, and the efficiency is effectively improved.

[0039] The jig body 20 is a hollow structure, so that the weight of the entire jig body 20 is not too heavy. Specifically, the jig body 20 is a hollow 3D printing product.

[0040] In the embodiment, the bottom end of the jig body 20 is a non-closed end, the jig body 20 is internally provided with a support plate 23, and the support plate 23 and the jig body 20 form the fixing groove 22. The support plate 23 is arranged in the jig body 20, which can strengthen the strength of the jig body 20, and on the other hand, the bottom end of the jig body 20 is designed as a non-closed end, the support plate 23 and the jig body 20 form the fixing groove 22, so that the structure is more simple and the design is ingenious.

[0041] The number of the support plates 23 is two, and the two support plates 23 and the jig body 20 form the fixing groove 22, and the number of the fixing blocks 30 is two, and the two fixing blocks 30 are clamped at the two ends of the fixing groove 22. Specifically, the bottom end of the jig body 20 is an open non-closed end, and the two support plates 23 form a large approximately rectangular fixing groove 22, and the two fixing blocks 30 are clamped at the two ends of the fixing groove 22, so that the fixing block 30 can be fixed in the horizontal direction.

[0042] Cooperation Figures 4 to 6 The utility model discloses a laser engraving machine, including:

[0043] A workbench 40 is provided with a positioning plate 41, and the positioning plate 41 is provided with a plurality of positioning holes 42. The positioning plate 41 is provided with the frame 10 fixing jig as described above. The fixing block 30 is connected and fixed with the positioning hole 42 through a fastener. The jig body 20 is fixed on the positioning plate 41 through clamping with the fixing block 30.

[0044] An adjusting support 50 is provided with a laser head 51, and the laser head 51 is located above the positioning plate 41.

[0045] The positioning plate 41 is fixed on the workbench 40 through bolts. The positioning plate 41 is provided with a plurality of positioning holes 42, so as to fix the fixing jig at different positions according to actual needs, and the use is flexible. The fixing hole 31 on the fixing block 30 is correspondingly arranged with the positioning hole 42 on the positioning plate 41, that is, when the fixing block 30 is placed on the positioning plate 41, the fixing hole 31 and the positioning hole 42 can correspond one by one. Thus, the fixing hole 31 and the positioning hole 42 can be connected and fixed through a fastener (bolt), so as to fix the fixing block 30 on the positioning plate 41. In addition, in order to make the fixing block 30 more stable, the fixing hole 31 on one fixing block 30 includes at least two. The fixing block 30 is designed according to the fixing groove 22 of the jig body 20. After the fixing block 30 is fixed on the positioning plate 41, the jig body 20 is clamped and fixed with the fixing block 30, so as to fix the jig body 20 on the positioning plate 41.
