Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] In the description of the utility model, it is necessary to understand that the directions or positional relationships indicated by the terms "front", "rear", "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model.

[0030] like Figure 1-4 As shown, this embodiment discloses an automatic laser machine for locomotive rims, including a laser engraving station and a laser engraving robot 3. The laser engraving station includes a station frame 1, a lifting platform 2 and a clamping mechanism. The laser engraving robot 3 is installed on one side of the station frame 1. The laser engraving robot 3 can control the laser head to perform laser engraving operations. Because it belongs to conventional technical means, it is not described in detail here. In order to facilitate the conveying of locomotive rims, a roller conveyor line 4 is installed on the top of the station frame 1. The roller conveyor line 4 is designed with a notch that allows the clamping mechanism to extend. Visual sensors 5 are set on both sides of the roller conveyor line 4, and the position of the locomotive rim can be accurately detected by the visual sensors 5.

[0031] A base plate 6 is installed in the work station frame 1, and a lifting cylinder is installed on the base plate 6. The movable end of the lifting cylinder is fixedly connected to the bottom of the lifting platform 2. In order to improve the lifting stability of the lifting platform 2, multiple sliding rods are installed at the bottom of the lifting platform 2, and a sliding sleeve that can slide with the sliding rod is installed on the base plate 6.

[0032] In order to stably support the locomotive rim, a supporting longitudinal plate 15 is provided on the supporting transverse plate 8. The supporting transverse plate 8 and the supporting longitudinal plate 15 are in a cross shape, and the lengths of the supporting longitudinal plate 15 and the supporting transverse plate 8 are both greater than the outer diameter of the locomotive rim. A supporting column 16 and a rotating motor 17 are provided on the lifting platform 2. The top of the supporting column 16 is rotatably connected to a driving gear, and the bottom of the motor box is connected to the top surface of the driving gear; the output shaft of the rotating motor 17 is installed with a driving gear, and the driving gear is connected to the driving gear through a chain. With such a design, the rotation angle of the clamping mechanism can be controlled by the rotating motor 17.

[0033] The specific working process of this utility model motorcycle circle automatic laser machine is as follows:

[0034] The locomotive rim is conveyed through the roller conveyor line 4. When it is detected that the locomotive rim reaches the center of the clamping mechanism below the laser engraving robot 3, the lifting cylinder 7 controls the lifting platform 2 to rise so that the locomotive rim is located in the clamping mechanism. The servo motor 14 controls the driving gear to rotate, so that the two clamping uprights move inward to support and position the outer circumferential wall of the locomotive rim. When the locomotive rim is fixed, the lifting platform 2 continues to rise to the working position of the laser engraving robot 3. The driving gear is controlled to rotate by the rotary motor 17 to adjust the angle of the locomotive rim. At the same time, the angle position of the air nozzle hole of the locomotive rim is detected by the visual sensor 5. After the position is determined, the locomotive rim is lasered multiple times by the laser engraving robot 3. After the laser operation is completed, the lifting platform 2 descends and controls the clamping mechanism to rotate so that it can pass through the gap on the roller conveyor line 4, so that the locomotive rim returns to the roller conveyor line 4. The utility model has a high overall degree of automation, ensures laser quality, reduces labor costs, and can save about 150,000 yuan per year.
