Description

Technical Field

[0001] The invention relates to the technical field of laser strengthening, and in particular to a gear surface laser strengthening device and a method thereof for a reducer. Background Art

[0002] After the production of the reducer gears is completed, their surfaces need to be strengthened. Laser strengthening of the gear surface is an advanced surface treatment technology that uses a high-energy-density laser beam to quickly heat and cool the gear surface, thereby changing its surface structure and performance, and achieving the purpose of improving the gear's wear resistance, fatigue resistance and load-bearing capacity. This technology is usually called laser surface quenching or laser phase transformation hardening. During the laser strengthening process, the laser beam scans the gear surface at an extremely high speed, causing the surface material to quickly heat up to above the phase transformation point in a very short time. Subsequently, when the laser beam is removed, due to the heat conduction of the workpiece matrix, the surface material quickly cools down, and a martensitic phase transformation or a bainitic phase transformation occurs, thereby completing the phase transformation strengthening process. Before laser strengthening, paint needs to be applied to the surface of each single tooth in turn.

[0003] However, when using the existing reducer gear surface laser strengthening device and method, it is not convenient to apply paint to the surface of each single tooth.

[0014] A method for laser strengthening the surface of a gear of a reducer, using the above-mentioned laser strengthening device for the surface of a gear of a reducer, comprises the following steps:

[0015] S1: The gear body is clamped and fixed by a clamping mechanism, and then the mounting plate and the support plate are moved by a manipulator, thereby moving the laser head, and at the same time, the roller rolls on the top of the single tooth;

[0016] S2: When the lower end of the hollow tube abuts against the side wall and the top of the single tooth, the hollow tube is pushed to move upward, and at the same time, the first spring is compressed. Moreover, when the hollow tube moves upward, the annular cover is driven to move downward synchronously, so that the annular cover moves out of the fixed ring. At this time, the paint in the paint box enters the annular cover through the liquid inlet hole, and drips onto the side wall and the top of the single tooth after passing through the hollow tube and the discharge hole.

[0017] S3: Under the action of the sponge block, the paint can be evenly applied to the surface of the single tooth, so that it is convenient to apply the paint to the surface of the single tooth, which is more convenient and quick to use.

[0019] S5: When the roller rolls on the top of the single tooth, the roller drives the rotating rod and the rotating disk to rotate. When the conical block abuts against the side wall of the push frame, the moving block is pushed to move toward the connecting block. At the same time, the second spring is compressed. When the push frame passes over the conical block, the moving block can move and reset under the action of the second spring. This reciprocating movement can make the moving block move back and forth and drive the bristles to move synchronously. Therefore, after laser strengthening, the surface of the single tooth can be reciprocated by the bristles to remove excess coating on the surface, which is more convenient and quick to use.

[0020] S6: Then, the second motor is started. The rotation of the second motor drives the rotation of the rotating shaft and the mounting seat, and then drives the expansion sleeve and the gear body to rotate a certain angle, so that another single tooth can be laser strengthened.

[0023] (2) The gear surface laser strengthening device and method of the reducer are provided with a lifting mechanism, etc., so that when laser strengthening is performed, the roller rolls on the top of the single tooth, which can ensure that the distance between the laser head and the single tooth is constant, thereby ensuring the quality of laser strengthening. In addition, by starting the first motor, the rotation of the first motor drives the rotation of the threaded rod, so that the threaded rod is lifted and moved along the threaded tube. At the same time, the sleeve rod is lifted and moved along the sleeve, thereby driving the T-plate and the laser head to be lifted and moved, thereby adjusting the distance between the laser head and the single tooth, and the applicability is stronger.

[0024] (3) The gear surface laser strengthening device and method of the reducer are provided with a cleaning mechanism, etc., so that when laser strengthening is performed, the roller rolls on the top of the single tooth. At the same time, when the roller rolls, it drives the rotating rod and the rotating disk to rotate.

7. A method for laser strengthening the gear surface of a reducer, using the laser strengthening device for the gear surface of a reducer as claimed in claim 6, characterized in that: The following steps are involved: S1: The gear body is clamped and fixed by a clamping mechanism (9), and then the mounting plate (13) and the support plate (14) are moved by a manipulator (12), thereby moving the laser head (15), and at the same time, the roller (701) rolls on the top of the single tooth; S2: When the lower end of the hollow tube (18) abuts against the side wall and the top of the single tooth, the hollow tube (18) is pushed to move upward, and at the same time, the first spring (203) is compressed. Moreover, when the hollow tube (18) moves upward, the annular cover (202) is driven to move downward synchronously, so that the annular cover (202) moves out of the fixed ring (302). At this time, the paint in the paint box (16) enters the annular cover (202) through the liquid inlet hole (301), passes through the hollow tube (18) and the discharge hole (11), and then drips onto the side wall and the top of the single tooth; S3: Under the action of the sponge block (10), the coating can be evenly applied to the surface of the single tooth, thereby facilitating the coating of the surface of the single tooth, making it more convenient and quick to use, while ensuring the coating effect, thereby improving the efficiency and quality of laser strengthening, and allowing the roller (701) to roll on the top of the single tooth; S4: When laser strengthening is performed, the roller (701) rolls on the top of the single tooth, which can ensure that the distance between the laser head (15) and the single tooth is constant, thereby ensuring the quality of laser strengthening, and by starting the first motor (806), the rotation of the first motor (806) drives the rotation of the threaded rod (805), so that the threaded rod (805) moves up and down along the threaded tube (804), and at the same time, the sleeve rod (802) moves up and down along the sleeve tube (801), thereby driving the T-shaped plate (803) and the laser head (15) to move up and down, thereby adjusting the distance between the laser head (15) and the single tooth, and the applicability is stronger; S5: When the roller (701) rolls on the top of the single tooth, when the roller (701) rolls, it drives the rotating rod (702) and the rotating disk (604) to rotate, and when the conical block (605) abuts against the side wall of the pushing frame (603), the moving block (401) is pushed to move in a direction close to the connecting block (501). At the same time, the second spring (503) is compressed. When the pushing frame (603) passes over the conical block (605), the moving block (401) can move and reset under the action of the second spring (503). In this way, the moving block (401) can move back and forth and drive the bristles (402) to move synchronously, so that after laser strengthening, the surface of the single tooth can be reciprocated by the bristles (402) to remove excess coating on the surface, which is more convenient and quick to use; S6: Then, the second motor (902) is started. The rotation of the second motor (902) drives the rotation of the rotating shaft (903) and the mounting seat (904), thereby driving the expansion sleeve (905) and the gear body to rotate at a certain angle, so that another single tooth can be laser strengthened.
