Description

Technical Field

[0001] The invention belongs to the technical field of gear marking, and in particular relates to a marking device and a marking method for manufacturing mechanical accessory gears. Background Art

[0002] Marking is the process of marking a product to distinguish between acceptable and unacceptable items. Laser marking is a common method used in the machinery manufacturing industry. Gears, standard components in the machinery manufacturing industry, are typically marked with markings such as model numbers or batch numbers. These markings serve not only to distinguish acceptable from unacceptable products but also to identify the type and batch of the gear.

[0003] Currently, commonly used marking machines consist of a workbench for placing gears, a bracket mounted on the workbench, and a laser head mounted on the bracket. During operation, the operator must place the gears one by one on the workbench directly opposite the laser head, then activate the laser head to mark each gear. The marking process requires the operator to constantly remove and place the gears, making the operation very tedious and labor-intensive. The low level of mechanization hinders efficiency and time. To address this issue, we provide a marking device and method for manufacturing gears used in mechanical parts to address these challenges. Summary of the Invention

[0004] The present invention provides a marking device and marking method for manufacturing mechanical parts gears. By controlling the reciprocating up and down movement of a hydraulic cylinder, a conveyor plate is intermittently fed to the bottom of a laser marking machine, and the marked gears are intermittently unloaded. Synchronously, the reciprocating movement of a U-shaped push plate in a push assembly pushes the unloaded gears away, thereby completing the unloading of the marked gears. This makes the loading, unloading, and unloading of the gear marking operations more mechanized, thereby reducing the workload of the operator and effectively improving production efficiency. This solves the problem that the existing marking machine includes a workbench for placing gears, a bracket mounted on the workbench, and a laser head mounted on the bracket. During operation, the operator needs to place the gears one by one on the workbench in a position directly opposite the laser head, and then start the laser head to mark the gears one by one. During the marking process, the operator needs to constantly pick up and place the gears, which is very cumbersome and labor-intensive. Due to the low degree of mechanization, it is not conducive to improving the marking operation efficiency and shortening the marking time.

[0044] The operation process of this embodiment is as follows: through the reciprocating up and down movement of the first tooth plate 205, the first tooth plate 205 drives the second tooth plate 207 to rotate through the connecting rod 206, and then the second tooth plate 207 drives the second spur gear 409 meshing with it to rotate, so that the second spur gear 409 drives the power bevel gear 410 to rotate through the second transmission rod 408, so that the power bevel gear 410 drives the driven bevel gear 413 meshing with it to rotate, and then drives the rotating rod 412 and the rotating disk 414 to rotate, so that the rotating disk 414 drives the connecting column 415 to rotate, so that the connecting column 415 passes through the push-pull plate 416. The push-pull rod 404 is driven to move back and forth in the horizontal direction, so that the push-pull rod 404 drives the U-shaped push plate 401 to move back and forth along the guide plate 121 through the connecting plate 403 and the cross bar 402, thereby providing power for the reciprocating movement of the U-shaped push plate 401 (with the movement of the first tooth plate 205, the second tooth plate 207 will be driven to move, so that the position of the turntable 414 and the connecting column 415 will move, wherein the movement margin of the U-shaped push plate 401 is able to meet the position offset margin of the turntable 414 and the connecting column 415, so that the U-shaped push plate 401 will not interfere with the falling gear).

[0045] The working principle of the present invention is as follows: the gear is placed between the positioning arc groove 106 and the limiting ring plate 107, and then the hydraulic cylinder 201 is started, so that the hydraulic cylinder 201 drives the first tooth plate 205 and the second tooth plate 207 to move downward through the movable plate 204; then, the conveying plate 105 is synchronously driven to move in the direction close to the laser marking machine 203, so that the gear is rotated just below the laser marking machine 203. At this time, the laser marking machine 203 just moves downward to the appropriate marking height. At the same time, the gear marked in the positioning arc groove 106 at the relative position of the laser marking machine 203 is just pushed into the unloading port 108 through the conveying plate 105; then, the marking operation of the gear is completed by the laser marking machine 203, and the U-shaped push plate 401 in the pushing assembly 4 is controlled to move in the direction close to and away from the conveying plate 105, so that the previously marked gear is pushed away, thereby completing the unloading of the gear.
