Description

Technical Field

[0001] This utility model relates to the field of automatic welding technology for automotive sensors, and in particular to a rotating mechanism with cooling clamping. Background Technology

[0002] Laser welding is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Essentially, laser welding involves the thermal fusion of two materials. During the welding process, the high temperature melts the metal, and the resulting heat is conducted to the upper and lower electrodes. If the electrodes are not cooled in time, it will affect the welding effect of the next product and shorten the lifespan of the electrodes. Existing cooling technologies use a cold air gun to blow cooling air onto the electrodes. However, for some high-speed production equipment, the air cooling time is short, and the electrode cooling effect is not ideal. A Chinese patent discloses a "cooling mechanism for a welding station of a thermal battery" (application number CN202221031624.6), which uses a movable cooling cover to cool the battery during the welding process, making cooling convenient and quick. However, the cooling effect of this mechanism is not ideal. Utility Model Content

[0026] Reference Figure 1-6This utility model discloses a rotating clamping mechanism with cooling, comprising: an upper rotating component fixing plate 1, a turntable 23 rotatably connected to the lower end of the upper rotating component fixing plate 1 for automatic welding, the turntable 23 being provided with a fixture 6 as the welding object, the fixture 6 being evenly distributed around the turntable 23, an upper rotating component carrier 2 fixedly connected to the upper end of the upper rotating component fixing plate 1 for fixing a lifting cylinder 3, an upper rotating component servo motor 4, and an upper rotating joint 10, an upper protective cover 5 fixedly connected to the upper rotating component carrier 2 for dust protection of the mechanism components, a dustproof plate 11 fixedly connected to the lower end of the upper protective cover 5 for dust protection of the mechanism components, and a front end of the upper rotating component carrier 2 being fixed... The mechanism is connected to a lifting cylinder 3, an upper rotating component servo motor 4, and an upper rotating joint 10 for welding and adjustment. The output end of the upper rotating component servo motor 4 is connected to the upper rotating joint 10 via an upper synchronous pulley and synchronous belt 9. The lower end of the upper rotating joint 10 is fixedly connected to an upper electrode 8 for welding. The upper end of the upper rotating component fixing plate 1 is fixedly connected to a dust cover cylinder 7 for adjusting the upper protective cover 5. The dust cover cylinder 7 is fixedly connected to the upper protective cover 5. The upper rotating joint 10 is equipped with an upper cooling spindle 12 for cooling. The lower end of the upper cooling spindle 12 is equipped with an upper chuck 13 for clamping and fixing. The upper end of the upper electrode 8 abuts against the upper chuck 13, and the lower end of the upper electrode 8 abuts against the fixture 6.

[0027] The lower rotating component fixing plate 14 and the lower rotating component carrier 15 are fixedly connected to the lower protective cover 24 to protect the mechanism components from dust. The lower rotating component fixing plate 14 is located below the upper rotating component fixing plate 1. The lower rotating component fixing plate 14 is fixedly connected to the lower rotating component carrier 15, which fixes the electric push rod 18, the lower rotating component servo motor 17 and the lower rotating joint 22. The front end of the lower rotating component carrier 15 is fixedly connected to the electric push rod 18, the lower rotating component servo motor 17 and the lower rotating joint 22 for welding and adjustment of the mechanism. The output end of the lower rotating component servo motor 17 is connected to the lower rotating joint 22 through the lower synchronous pulley and synchronous belt 19. The upper end of the lower rotating joint 22 is fixedly connected to the lower electrode 16 for welding. The lower rotating joint 22 is provided with a lower cooling spindle 21 for cooling. The upper end of the lower cooling spindle 21 is provided with a lower chuck 20 for clamping and fixing. The lower end of the lower electrode 16 abuts against the lower chuck 20 and the lower end of the lower electrode 16 abuts against the fixture 6.

[0028] Working principle: The automatic welding of automotive sensors is performed using a rotating mechanism with cooling clamping. After the fixture 6 is in place, the lifting cylinder 3 extends, and the upper electrode 8 presses down on the product in the fixture 6. The dust cover cylinder 7 extends, causing the dust cover plate 11 to extend and form a sealed space with the upper protective cover 5 to prevent welding dust from spreading. The lower rotating component of the rotating mechanism with cooling clamping uses an electric push rod 18 to lift the lower electrode 16 to the lower surface of the product in the fixture 6, and then continues to lift it upwards for a distance, causing the product to detach from the fixture 6. At the same time, the upper electrode 8 and the lower electrode 16 clamp the product. At this time, the servo motor 4 of the upper rotating component drives the upper electrode 8 under the upper cooling spindle 12 to rotate through the upper synchronous pulley and synchronous belt 9. At the same time, the servo motor 17 of the lower rotating component drives the lower electrode 16 on the lower cooling spindle 21 to rotate synchronously through the lower synchronous pulley and synchronous belt 19, thus completing the welding.

[0029] After welding is completed, the lifting cylinder 3 and the electric push rod 18 retract. At this time, the factory cooling water is circulated to the upper cooling spindle 12 and the lower cooling spindle 21 through the upper rotary joint 10 and the lower rotary joint 22, respectively, so that the two cooling spindles are cooled quickly. According to the principle of heat conduction, the heat on the upper chuck 13 and the lower chuck 20 is quickly conducted to the upper cooling spindle 12 and the lower cooling spindle 21, and the heat on the upper electrode 8 and the lower electrode 16 is quickly conducted to the upper chuck 13 and the lower chuck 20, and so on, so that the upper electrode 8 and the lower electrode 16 are cooled quickly.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
