A fixed rod is fixedly installed on the top of the square plate, and a pulley frame is fixedly installed on the surface of the fixed rod. A correction plate is slidably installed on the top of the protective plate. First, the motorcycle accessories to be marked are placed on the protective plate, and then the content to be printed is adjusted on the display screen. When it is confirmed, the motor is started. The rotation of the motor will drive the spiral rotating rod to rotate, and the rotation of the spiral rotating rod will drive the two moving blocks to move toward each other, and the relative movement of the moving blocks will drive the clamping plates to move toward each other.

[0007] According to the above technical solution, a connecting plate is fixedly installed at the bottom of the correction plate, a sliding frame is slidably installed on the inner wall of the protection plate, a triangular block is fixedly installed on the surface of the sliding frame, a triangular plate is slidably installed on the inner wall of the protection plate, and an arc plate is fixedly installed on the top of the triangular plate. A reset spring is arranged between the protection plate and the triangular plate, and a slope is arranged on the side of the correction plate close to the pulley frame. A No. 1 spring is arranged between the protection plate and the correction plate. When the sliding frame moves upward, it will push the triangular plate to move away from the sliding frame, and when the triangular plate moves away from the sliding frame, it will drive the arc plate to move away from the sliding frame. When the correction plate is disengaged from the pulley frame, the elastic force of the No. 1 spring itself will drive the correction plate to reset.

[0008] According to the above technical solution, a cleaning device for cleaning impurities and a protective device for protecting the laser marking equipment are provided on the top of the fixing rod. The cleaning device includes a fixed block, a connecting frame and a cleaning brush. The fixed block is driven to move in the direction close to the motorcycle accessories by the fixing rod moving in the direction close to the motorcycle accessories.

The L-shaped rod is driven to move in the direction close to the motorcycle accessories by the connecting frame. The movement of the L-shaped rod in the direction close to the motorcycle accessories will drive the roller to move in the direction close to the motorcycle accessories. The movement of the roller in the direction close to the motorcycle accessories will push the trapezoidal plate downward. The L-shaped rod is fixedly mounted on the surface of the connecting frame, the roller is rotatably mounted on the surface of the L-shaped rod, and the trapezoidal plate is slidably mounted on the surface of the air pressure box.

[0012] According to the above technical solution, a long rod is fixedly installed on the top of the connecting rod, a U-shaped frame is slidably installed on the bottom of the laser marking equipment, a fixed plate is fixedly installed on the surface of the U-shaped frame, a rotating rod is rotatably installed on the bottom of the laser marking equipment, and a baffle is fixedly installed on the surface of the rotating rod. When the U-shaped frame moves away from the long rod, it will push the rotating rod to rotate in the direction away from the long rod, and when the rotating rod rotates away from the long rod, it will drive the baffle to rotate in the direction away from the long rod.

[0013] According to the above technical solution, a No. 3 spring is arranged between the trapezoidal plate and the air pressure box. When the trapezoidal plate is separated from the roller, the elastic force of the No. 3 spring itself will drive the trapezoidal plate to reset. A No. 4 spring is arranged between the laser marking device and the U-shaped frame. When the long rod is separated from the fixed plate, the elastic force of the No. 4 spring itself will drive the U-shaped frame to reset. A No. 1 torsion spring is arranged between the laser marking device and the rotating rod. When the U-shaped frame is separated from the rotating rod, the elastic force of the No. 1 torsion spring itself will drive the rotating rod to reset.

[0014] The present invention provides a laser marking machine for motorcycle parts processing. It has the following beneficial effects: (1) This invention clamps motorcycle accessories by means of a clamping plate to prevent the motorcycle accessories from being displaced during the laser printing process, which would cause the printing to be offset and affect the laser marking effect. By correcting the position of the motorcycle accessories before clamping them with the clamping plate, it can effectively prevent the position of the motorcycle accessories from being deviated during clamping, which would cause the clamping plate to damage the surface of the motorcycle accessories and affect the normal use of the motorcycle accessories. The inner wall of the motorcycle accessories is supported by an arc plate to prevent slight deformation due to uneven heating, which would cause the entire accessory to be unbalanced and affect the laser marking effect. The support can maintain the stability of the workpiece, avoid bending or deformation during the marking process, and ensure the marking quality and accuracy.

[0015] (2) This invention uses a soft-bristle brush to move toward the motorcycle accessories to scrape off dust or impurities attached to the motorcycle accessories, preventing surface impurities from scattering the laser beam and reducing the focusing accuracy of the laser beam, thereby affecting the details and clarity of the marking. At the same time, the gas ejected from the air outlet is used in conjunction with the soft-bristle brush to remove dust and impurities attached to the motorcycle accessories, preventing the laser beam from acting evenly on the surface of the workpiece during laser marking, resulting in unclear or incomplete marking.

[0016] (3) This invention gradually covers the air outlet by moving the trapezoidal plate downward, so that the smaller the air outlet, the stronger the gas ejected. By gradually increasing the wind force, the direction of dust blowing can be more effectively controlled to avoid polluting the surrounding environment. At the same time, the rotation of the rotating rod away from the long rod will drive the baffle to rotate away from the long rod. The baffle is moved away from the long rod to open the bottom of the laser marking equipment, preventing long-term exposure to air from causing aging, fading or brittleness of the lens coating, thereby reducing the optical performance and service life of the lens.
