DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0016] As shown in the drawings, Figs. 1-2 A hub laser engraving positioning tool includes a chassis 1, a support plate 4, an indexing head 5, a chuck 7, and a mounting piece 8. The support plate 4 is located above the chassis 1, and a plurality of support columns 3 are connected between the chassis 1 and the support plate 4. The support columns 3 are perpendicular to the chassis 1 and the support plate 4, respectively. The indexing head 5 is installed on the support plate 4. Specifically, a U-shaped mounting gap is formed in the outer periphery of the indexing head 5, and a fixing bolt 6 is arranged in the mounting gap. The lower end of the fixing bolt 6 is screwed into the support plate 4, and the upper end of the fixing bolt 6 abuts against the upper end face of the mounting gap, thereby completing the fixed installation of the indexing head 5.

[0017] The chuck 7 is installed on the indexing head 5, and the chuck 7 includes a chuck body 9 and three movable jaws 10. The three movable jaws 10 are evenly distributed on the chuck body 9. The mounting piece 8 includes a positioning shaft 11. The upper end of the positioning shaft 11 is connected with a threaded column 13. The threaded column 13 is threadedly connected with a nut 15. The outer periphery of the nut 15 is connected with a plurality of handles 16.

[0018] The three movable jaws 10 are controlled to move inward to clamp the end of the positioning shaft 11 of the mounting piece 8. The shaft hole of the hub to be processed is aligned with the positioning shaft 11 and is lowered, so that the positioning shaft 11 is inserted into the shaft hole of the hub, and then a positioning sleeve 14 is sleeved on the positioning shaft 11. The nut 15 is threadedly connected on the threaded column 13 and is tightened with a tightening torque of 15-20 N·m. The lower end of the nut 15 abuts against the positioning sleeve 14 and moves downward, so that the positioning sleeve 14 abuts against the upper end face of the hub, and the lower end face of the hub is abutted by the upper end face of the movable jaw 10, thereby completing the fixation of the hub. The clamping of the hub is convenient, and the working efficiency is significantly improved.

[0019] Adjust the laser focus to the best working distance, and perform the first inscription. If multi-angle inscription is required, adjust the angle of the hub through the indexing head 5 so that the surface to be inscribed on the hub is perpendicular to the laser source. Precise angle adjustment is achieved through the indexing head, which makes it easier to adjust the angle of the hub and meet the inscription requirements of each surface of the hub.

[0020] In order to avoid the wear caused by the direct contact between the end surface of the hub and the movable jaw 10, a positioning ring 12 is arranged at the end of the positioning shaft 11 close to the chuck body 9, and the diameter of the positioning ring 12 is greater than that of the positioning shaft 11. When the hub is sleeved on the positioning shaft 11, the upper end surface of the positioning ring 12 can abut against the lower end surface of the hub, avoiding the direct contact between the hub and the movable jaw 10 and protecting the lower end surface of the hub. Meanwhile, the lower end surface of the positioning ring 12 can abut against the upper end surface of the movable jaw 10, which can position the positioning shaft 11 when the movable jaw 10 clamps the positioning shaft 11, so as to ensure the consistency of the subsequent installation positions of the hub.

[0021] A plurality of mounting holes 2 are arranged on the chassis 1, which are used to fix the device to the laser inscription equipment and ensure that the installation flatness error is less than or equal to 0.02 mm.

[0022] The above only describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the concept of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principles of the present application are also considered to be within the protection scope of the present application.
