AI Technical Summary
Traditional heavy-duty turntable mechanisms for aluminum spot welding clamps cannot guarantee the stable movement and limiting of the aluminum spot welding clamps, affecting the stable operation of the heavy-duty turntable mechanism.
By adjusting the coordination between the motor and the rotating gear, the transmission gear is driven to rotate. The L-shaped frame and the external gear cylinder limit the transmission gear. Combined with the coordination between the clamping motor and the drive gear, the adjusting cylinder and the clamping rod slide within the limiting plate. The repulsive force of the magnetic ring assists in the damping of the placement plate, achieving stable movement and limiting.
It achieves stable movement and limiting of the aluminum spot welding clamp, ensures stable operation of the heavy-duty turntable mechanism, and reduces the impact of vibration.

[0008] As a preferred embodiment of this utility model, an L-shaped frame is rotatably connected to the outer edge of the external gear cylinder. An adjusting motor is fixedly mounted on the top of the L-shaped frame. The output shaft at the bottom of the adjusting motor passes through the inner wall of the L-shaped frame and is fixedly sleeved with a rotating gear. A transmission gear is rotatably connected to the bottom of the L-shaped frame, and the convex teeth on the outer edge of the transmission gear mesh with the convex teeth on the outer edge of the rotating gear and the convex teeth on the outer edge of the external gear cylinder.

[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. This heavy-duty turntable mechanism for aluminum spot welding clamps works by adjusting the coordination of a motor and a rotating gear. The motor drives the rotating gear to rotate, which in turn drives the transmission gear. An L-shaped frame and an external gear cylinder assist in limiting the transmission gear. The transmission gear then drives the L-shaped frame to rotate on the outer edge of the external gear cylinder. Rollers two and three assist in stabilizing the movement of the transmission gear and the rotating gear. When the motor stops operating, the electric telescopic rod drives the brake pads to move until the inner wall of the brake pads is in close contact with the outer edge of the friction ring, thereby assisting in stabilizing and limiting the L-shaped frame.
[0014] 2. This heavy-duty turntable mechanism for aluminum spot welding clamps works by using a clamping motor and a drive gear. The clamping motor drives the drive gear to rotate, which in turn drives the adjusting cylinder to rotate within the inner wall of the outer gear cylinder via the internal gear ring. The adjusting cylinder then drives the side of the clamping rod to slide on the inner wall of the limiting plate via the arc groove. The inner wall of the circular plate assists in the stable movement of the clamping rod, thereby clamping and limiting the workpiece.
[0015] 3. The heavy-duty turntable mechanism for aluminum spot welding clamps uses the cooperation of the outer cylinder and the sliding cylinder. When the top of the placement plate is in operation, the sliding cylinder slides on the inner wall of the outer cylinder under the pressure of the placement plate, thereby helping the bottom of the first magnet ring and the top of the second magnet ring to approach each other. The bottom of the first magnet ring and the top of the second magnet ring repel each other, thereby helping to reduce the vibration of the top of the placement plate and ensuring the stable operation of the device.

[0031] Working principle: When the device is in use, the regulating motor 17 drives the rotating gear 18 to rotate, which in turn drives the transmission gear 19 to rotate. The L-shaped frame 16 and the external gear cylinder 5 assist in limiting the movement of the transmission gear 19. The transmission gear 19 then drives the L-shaped frame 16 to rotate around the outer edge of the external gear cylinder 5. Rollers 20 and 21 assist in stabilizing the movement of the transmission gear 19 and the rotating gear 18. When the regulating motor 17 stops operating, the electric telescopic rod 22 drives the brake pad 23 to move until the inner wall of the brake pad 23 is in close contact with the outer edge of the friction ring 25, thus assisting in stabilizing the L-shaped frame 16. The clamping motor 7 then drives the drive gear 8. The rotation of the drive gear 8, via the internal gear ring 14, causes the adjusting cylinder 12 to rotate within the inner wall of the outer gear cylinder 5. The adjusting cylinder 12, through the arc-shaped groove 13, causes the side of the clamping rod 10 to slide on the inner wall of the limiting plate 11. The inner wall of the circular plate 9 assists in the stable movement of the clamping rod 10, thus clamping and limiting the workpiece. When the top of the placement plate 4 operates, the sliding cylinder 3 slides on the inner wall of the outer cylinder 2 under the downward pressure of the placement plate 4. This helps the bottom of the first magnet ring 28 and the top of the second magnet ring 29 to approach each other, while the bottom of the first magnet ring 28 and the top of the second magnet ring 29 repel each other, thus helping to reduce vibration at the top of the placement plate 4 and ensuring stable operation of the device.
