[0002] A hub is a metal component used for support inside a tire. In order to facilitate the classification of hub models and specifications, a coding device is used to spray codes on the surface of the hub. For example, a coding and marking device for mechanical processing proposed in the patent with the application number 202222498511.3 includes a frame device that supports and fixes and provides rotational power. Four clamping devices for clamping different-sized components are evenly arranged on the frame device. Above the clamping device, there is a coding device for adjusting the coding position and coding and marking the components. On one side of the coding device, there is a drying device for hot-air drying the components after coding; the coding device includes a first support frame, and a screw rod is rotatably connected between the first support frames. One end of the screw rod is provided with a handle. The coding and marking device for mechanical processing described in the above solution can adjust the coding position through the setting of threaded meshing transmission, improving adaptability; through the setting of elastic clamping, it can clamp different-sized components, improving practicality; through the setting of hot-air drying, it can improve the quality of coding and the coding effect is good.

[0003] When the existing hub coding device sprays codes on the inclined surface position of the hub surface, it is necessary for workers to first adjust the position of the hub manually. The operation is not only relatively cumbersome, but also the accuracy of position adjustment is poor, resulting in deviation of the coding position. Therefore, we have made improvements and proposed a coding device for hub processing. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a coding device for hub processing, which can effectively solve the problem that when the hub coding device sprays codes on the inclined surface position of the hub surface, it is necessary for workers to first adjust the position of the hub manually. The operation is not only relatively cumbersome, but also the accuracy of position adjustment is poor, resulting in deviation of the coding position.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

Specific embodiments

[0021] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figure 1 shown, an inkjet coding device for hub processing includes a workbench 1. A through groove 2 is penetrated and opened on the upper surface of the workbench 1. A mounting plate 3 is arranged inside the through groove 2. A fixing mechanism 4 for clamping a workpiece is arranged on the surface of the mounting plate 3. A three-axis moving platform 5 is further installed on the upper surface of the workbench 1. The output end of the three-axis moving platform 5 is installed with a connecting plate 6, and an inkjet head 7 is installed on the lower surface of the connecting plate 6.

[0023] As Figure 2 shown, a first rotary cylinder 101 is installed in the middle of one end surface of the workbench 1. Rotating rods 301 are fixedly installed in the middle of both end surfaces of the mounting plate 3. One end of one rotating rod 301 is rotatably arranged on the inner wall of one end of the through groove 2, and one end of the other rotating rod 301 is fixedly connected to the output end of the first rotary cylinder 101.

[0024] Driven by the first rotary cylinder 101, the rotating rod 301 can drive the mounting plate 3 to rotate, so as to adjust the overall angle of the hub, which is convenient for inkjet coding on the inclined surface position of the hub.

[0025] As Figure 2 , Figure 3 , Figure 4As shown in the figure, a circular groove 302 is formed on the upper surface of the mounting plate 3. The fixing mechanism 4 includes a circular plate 401 and a second rotary cylinder 402. The circular plate 401 is rotatably arranged inside the circular groove 302. The second rotary cylinder 402 is fixedly installed at the center of the lower surface of the mounting plate 3. The output end of the second rotary cylinder 402 is provided with a rotating column 403. One end of the rotating column 403 is arranged inside the circular groove 302 and its end is fixedly connected to the center of the lower surface of the circular plate 401. A limiting block 4011 is arranged on the outer surface of the circular plate 401. A limiting groove 3021 matched with the limiting block 4011 is formed on the inner wall of the circular groove 302. Installation grooves 404 are formed on both sides of the upper surface of the circular plate 401. A driving motor 405 is installed on one side of the outer surface of the circular plate 401. The output end of the driving motor 405 is provided with a bidirectional lead screw 406. One end of the bidirectional lead screw 406 is rotatably arranged on the inner wall of one end of the installation groove 404. Threaded sleeves 407 are movably installed on both side rods of the bidirectional lead screw 406. A clamping block 408 is installed on the top of each threaded sleeve 407. Arc surfaces 409 are arranged on both sides of each clamping block 408.

[0026] Through the meshing transmission between the bidirectional lead screw 406 and the threaded sleeve 407, the distance between the two clamping blocks 408 can be adjusted under the drive of the driving motor 405, so as to fix the position of the wheel hub, which is convenient for the inkjet coding work. Through the cooperation between the limiting block 4011 and the limiting groove 3021, the circular plate 401 can be rotatably arranged inside the circular groove 302. While limiting the position of the circular plate 401, it can also make it more stable during the rotation process.

[0027] The working principle of this inkjet coding device for wheel hub processing:

[0028] When in use, the wheel hub to be coded is placed above the circular plate 401, and the bidirectional screw rod 406 is driven to rotate by the driving motor 405. Under the meshing action between the bidirectional screw rod 406 and the screw rod sleeve 407, the clamping block 408 can be driven to move, so that the two clamping blocks 408 can clamp and fix the wheel hub, and then the position of the spraying terminal 7 is adjusted by the three-axis moving platform 5. The surface of the wheel hub is coded by the spraying terminal 7. The two sides of the clamping block 408 are provided with arc surfaces 409, and the inner wall or outer wall of the wheel hub can be clamped to complete the fixation of the position, which is more convenient during use. The rotating column 403 is driven to rotate by the second rotating cylinder 402 The circular plate 401 can be rotated to adjust the position of the fixed wheel hub, which is convenient for coding at different positions. The first rotating cylinder 101 drives the rotating rod 301 to rotate, which can drive the mounting plate 3 to rotate with the rotating rod 301 as the axis, so that the inclination angle of the wheel hub can be adjusted, so that the inclined surface position of the wheel hub surface can be coded. With the overall rotation of the circular plate 401, coding can be performed at different positions without manually adjusting the position of the wheel hub. The fixed wheel hub can be adjusted by the operation of the first rotating cylinder 101 and the second rotating cylinder 402, with higher adjustment accuracy, so that the coding position is more accurate.

[0029] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
