Description

Technical Field

[0001] This invention relates to a marking device, specifically a rapid impact marking device, which is used to mark various product surfaces with steel needle dots, steel stamps, and other qualification marks. Background Technology

[0002] Today, automotive engine parts undergo various tests during production, including dimensional checks, airtightness testing, and press-fit parameter testing. After passing multiple process tests, the parts are then required to be labeled as qualified products. Common labeling processes involve using steel pin dots or stamps to mark numbers and letters for easy product inspection and traceability. Automated labeling often requires a power unit installed on the equipment, which uses qualified electrical pulse signals to complete the automatic labeling. Traditional designs use ordinary cylinders, hydraulic cylinders, and springs as power units, but these structures lack sufficient power, resulting in unclear labels and affecting product traceability. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a rapid impact marking device that can output a powerful driving force and quickly mark the product surface with qualified markings.

[0004] The objective of this invention is achieved through the following technical solution: a rapid impact marking device, comprising a cylinder body and a piston rod, wherein an exhaust groove is provided on the piston rod and inside the cylinder body, and an air inlet and an air outlet are respectively provided on the cylinder body in the same row, wherein the air inlet, exhaust groove and air outlet are connected by an air passage, a cylinder sealing cover plate is installed on the cylinder body and at the head of the piston rod, a piston guide screw is installed on the cylinder sealing cover plate, the tail of the piston guide screw is connected to the exhaust groove, and a steel stamping rod is installed on the outer end of the piston rod.

[0005] An intake sealing ring is installed between the tail of the piston rod and the inner wall of the cylinder body, an exhaust sealing ring is installed between the head of the piston rod and the cylinder sealing cover plate, and a cover plate sealing ring is installed between the cylinder sealing cover plate and the inner wall of the cylinder body.

[0006] A screw is mounted on the piston rod, which secures the stamped rod by pressing against it. The cylinder sealing cover is bolted to the cylinder body. A number or letter marking is engraved on the top of the stamped rod.

[0007] By adopting the structure of this invention, the reciprocating motion of the piston rod is controlled. The piston rod is designed with exhaust grooves, which enhance its exhaust capacity. Combined with the inlet sealing ring, cover sealing ring, and exhaust sealing ring, the piston rod generates instantaneous inertia and a powerful pushing and impact force. This allows the stamping rod to quickly and clearly mark the product surface, ensuring product traceability. This invention features a simplified structure, is easy to manufacture and maintain, and has low cost. It can be widely used as a common impact tool in product marking processes.

[0009] Figure 2 for Figure 1 Internal cross-sectional view. Detailed Implementation

[0010] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0011] Reference Figure 1 , Figure 2 The present invention relates to a rapid impact marking device, comprising a cylinder body 1 and a piston rod 5. An exhaust groove 13 is provided on the piston rod 5 and inside the cylinder body 1 (in a horizontal position). An air inlet 11 (at the tail of the cylinder body) and an air outlet 12 (at the head of the cylinder body) are respectively provided on the cylinder body 1 in the same row. The air inlet 11, the exhaust groove 13, and the air outlet 12 are connected by an air passage. A cylinder sealing cover plate 2 is installed on the cylinder body 1 (at the open end) and at the head of the piston rod 5. A piston guide screw 4 is installed on the cylinder sealing cover plate 2. The tail of the piston guide screw 4 is connected to the exhaust groove 13. A stamping rod 6 is installed on the outer end (in a horizontal position) of the piston rod 5.

[0012] An intake sealing ring 7 (near the intake port 11) is installed between the tail of the piston rod 5 and the inner wall of the cylinder body 1. An exhaust sealing ring 9 is installed between the head of the piston rod 5 and the cylinder sealing cover plate 2. A cover plate sealing ring 8 (near the exhaust port) is installed between the cylinder sealing cover plate 2 and the inner wall of the cylinder body 1. All three sealing rings—the intake sealing ring 7, the cover plate sealing ring 8, and the exhaust sealing ring 9—are O-rings. A screw 10 is installed on the piston rod 5 (in a longitudinal position), which presses against the stamped rod 6 to secure it. The cylinder sealing cover plate 2 (in a horizontal position) is connected to the cylinder body 1 by bolts 14. A number or letter marking 15 is engraved on the top of the stamped rod 6. The cylinder body 1 is mounted on a mounting base 3.

[0013] The piston rod 5 is installed in the cylinder bore of the cylinder body 1, with a clearance fit to ensure smooth reciprocating motion. An intake sealing ring 7 is fitted onto the tail of the piston rod 5, dividing the interior of the cylinder body 1 into two independent cavities corresponding to the intake and exhaust ports: an intake chamber and an exhaust chamber, thus realizing the reciprocating motion of the piston rod 5. The inner bore of the cylinder sealing cover plate 2 and the piston rod 5 are fitted with a clearance fit, and the cylinder sealing cover plate 2 is equipped with a cover plate sealing ring 8 to ensure the sealing of the entire cavity. A piston guide screw 4 is equipped on the cylinder sealing cover plate 2 to limit and position the piston rod 5. Simultaneously, the piston guide screw 4 itself has a sealing function to prevent cavity leakage. Its cooperation with the piston rod 5 and its exhaust groove 13 ensures the orientation and fixation of the numbers or letters on the top of the stamped rod 6, guaranteeing consistency. The cylinder sealing cover plate 2 is equipped with an exhaust sealing ring 9. Figure 2 As shown, the exhaust groove of the piston rod 5 moves to the right to the position of the exhaust sealing ring 9 and continues to move. Due to the presence of the exhaust groove of the piston rod 5, the exhaust capacity of the exhaust chamber is instantly enhanced. At this time, the air pressure in the intake chamber continues to act on the piston rod 5, thereby generating a strong pushing force and inertia. At the same time, the steel stamp rod 6 completes the marking work of the product. Subsequently, the functions of the intake port and the exhaust port are interchanged to realize the reset of the piston rod 5.

[0014] The working principle of this invention is as follows: By controlling the reciprocating motion of the piston rod 5, which is designed with an exhaust groove 13, the exhaust capacity is enhanced due to the presence of the exhaust groove. The piston rod 5 generates instantaneous inertia and a strong pushing force, thereby achieving the marking work on the surface of qualified automotive cylinder heads (or cylinder blocks). By adjusting the compressed air pressure and the groove size of the piston rod's exhaust groove as needed, marking processes with different impact forces can be achieved.

[0015] The above embodiments should not be considered as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
