[0002] The commonly used fixtures for circular marking machines are rotary chucks and roller rotary fixtures. Roller rotary fixtures consist of two synchronously rotating rollers. In use, the workpiece is placed directly onto the two rollers, which then drive the workpiece to rotate. However, because existing roller rotary fixtures lack workpiece restraint, the workpiece rotation is unstable, easily affecting the marking quality.

[0003] Therefore, there is an urgent need to develop a new type of circular marking machine. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a circular marking machine.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0019] Reference Figure 1-2As shown, a circular marking machine includes a base 1, on which a body assembly and a front-to-back rotating roller clamp 2 are fixed. A limiting assembly is provided on the front side of the rotating roller clamp 2. The limiting assembly includes a movable seat 8, a front-to-back position adjustment mechanism, a support seat 10, a lifting seat 11, and a lifting mechanism. The front-to-back position adjustment mechanism is installed on the base 1 and is located on the front side of the rotating roller clamp 2. The movable seat 8 is installed on the front-to-back position adjustment mechanism. The support seat 10 is connected to the movable seat 8 through an L-shaped bracket 9. The lifting seat 11 is located below the support seat 10 and is connected to the support seat 10 through the lifting mechanism. Two pressure rollers 12 are rotatably mounted on the back of the lifting seat 11, with the symmetrical planes of the two pressure rollers 12 overlapping the symmetrical planes of the two rollers.

[0020] The front and rear position adjustment mechanism includes a support plate 4 and a first screw 6. The two support plates 4 are fixed side by side on the base 1, and two front and rear first guide rods 5 are provided between them. The first screw 6 is arranged parallel to the first guide rods 5, and is rotatably connected to the two support plates 4. Its front end passes through the support plate 4 and is connected to a first handwheel 7. The movable seat 8 is threadedly connected to the first screw 6 and slidably connected to the two first guide rods 5.

[0021] The lifting mechanism includes a second screw 15. The top of the lifting seat 11 is provided with two vertical second guide rods 14. The second guide rods 14 slide through the support seat 10. The second screw 15 is arranged parallel to the second guide rods 14 and is threadedly connected to the support seat 10. Its lower end is rotatably connected to the lifting seat 11, and its upper end is connected to a second handwheel 16.

[0022] More specifically, the front end of the pressure roller 12 is provided with a limiting plate 13, the outer diameter of the limiting plate 13 being larger than the outer diameter of the pressure roller 12.

[0023] In use, the workpiece 3 is placed on the roller rotating fixture 2. The first screw 6 is rotated by the first handwheel 7, which drives the moving seat 8 to move backward along the first guide rod 5 until the back of the limiting plate 13 and the front face of the workpiece 3 are on the same vertical plane. Then, the second screw 15 is rotated by the second handwheel 16, which drives the lifting seat 11 to move downward under the guidance of the second guide rod 14 until the two pressure rollers 12 contact the outer wall of the workpiece 3. At this time, the back of the limiting plate 13 contacts the front face of the workpiece 3. When marking, the two rollers drive the workpiece 3 to rotate. At this time, the two pressure rollers 12 can prevent the workpiece 3 from jumping and make the rotation of the workpiece 3 more stable. At the same time, the limiting plate 13 at the front end of the pressure roller 12 can provide front and rear limits for the workpiece 3. Example 2

[0024] As a preferred embodiment of this utility model, this embodiment designs the fuselage components based on Embodiment 1, specifically as follows:

[0025] The machine body assembly includes a column 17, a geared motor 19, a slide 20, a square frame 21, a machine head 23, and a telescopic device. The column 17 is fixed on the base 1, and a vertical slide groove 1701 is provided on the column 17. A third screw 18 is rotatably installed in the slide groove 1701, and the upper end of the third screw 18 extends through to the top of the column 17. The geared motor 19 is installed on the top of the column 17, and its output end is connected to the upper end of the third screw 18. The slide 20 is slidably installed in the slide groove 1701 and is threadedly connected to the third screw 18. The square frame 21 is sleeved on the outside of the column 17 and is fixedly connected to the slide 20. A guide rail 22 parallel to the roller is fixed on the outer wall of the square frame 21 near the roller rotating clamp 2.

[0026] The marking head 23 is slidably connected to the guide rail 22 on one side. The marking head of the marking head 23 is vertically set and located on the symmetrical plane of the two rollers. The telescopic device is set parallel to the guide rail 22 and is fixed to the back of the square frame 21. Its output end is fixedly connected to the marking head 23 through the connecting plate 25.

[0027] Specifically, in this embodiment, the telescopic device is an electric push rod 24.

[0028] After the limit assembly is adjusted to the correct position, the reduction motor 19 is started, which drives the third screw 18 to rotate, thereby causing the slide block 20 to move downward along the slide groove 1701 until the marking head descends to the specified height; then the electric push rod 24 is started, and its output rod extends to drive the machine head 23 to move forward until the marking head moves to the marking position; then the machine head 23 is started, and with the cooperation of the roller rotating fixture 2, it performs the marking operation on the workpiece 3.

[0029] In summary, this device is equipped with a limiting component that works in conjunction with the roller rotating clamp 2. The height and front-to-back position of the pressure roller 12 inside the limiting component are adjustable, which can limit the workpiece 3 of different specifications, so that the workpiece 3 rotates stably, thereby ensuring the marking quality. This device has a novel structure, is easy to operate, and is highly practical.
