[0022] To address the technical problem of poor clamping stability of slewing bearings in existing technologies, which affects the efficiency of oil hole opening and the product quality of the slewing bearing, this utility model patent adopts the following technical method: The slewing bearing is placed on a support roller 7, which supports the slewing bearing. An arc-shaped clamping plate 4 is driven by a telescopic rod 15. A slider 5 is provided at the bottom of the arc-shaped clamping plate 4. The slider 5 slides within a limiting groove 14, providing clamping stability for the slewing bearing. After the arc-shaped clamping plate 4 and the slewing bearing are clamped and installed, the inner surface of the slewing bearing contacts the limiting roller 12, and then... (The sentence is incomplete and requires further context to translate accurately.) A sliding clamping plate 13 is installed, which slides downwards and clamps the top of the slewing bearing. Preferably, the bottom of the clamping plate 13 has a soft, wear-resistant layer to protect the surface of the slewing bearing. The clamping plate 13 is fixed by bolts, which abut against the sliding plate 11, thus fixing the clamping plate 13 to the top of the slewing bearing. This structure achieves radial and axial clamping of the slewing bearing, ensuring stable fixation during oil hole drilling operations, improving the efficiency of oil hole drilling, and enhancing the quality of the slewing bearing product.

[0023] When multiple oil holes need to be opened, the rolling of the support roller 7 and the limiting roller 12 allows the slewing bearing to be rotated and adjusted to the designated position for opening. This structure improves the efficiency of opening multiple oil holes in the slewing bearing and eliminates the need for hoisting and adjusting the slewing bearing. This method of opening multiple oil holes achieves high efficiency.

[0024] In at least one embodiment, to securely clamp the slewing bearing and ensure the accuracy and efficiency of the oil hole, the fixing groove 6 and the limiting block 2 are both formed in an arc shape. The fixing groove 6, the limiting block 2, and the processing platform 1 are arranged concentrically so that the fixing groove 6 and the limiting block 2 are both concentrically arranged with the slewing bearing and fit the structure of the slewing bearing to securely clamp the slewing bearing for oil hole opening.

[0025] In at least one embodiment, to achieve a stable clamping and fixing of the slewing bearing, an oil hole is provided, and the clamping plate 13 is arranged in an arc shape and is coaxial with the limiting block 2.

[0026] In at least one embodiment, in order to achieve axial clamping and fixing of the slewing bearing by the clamping plate 13, a sleeve bracket 16 is provided on one side of the clamping plate 13. The sleeve bracket 16 is configured to match the shape of the slide plate 11. The sleeve bracket 16 is installed on the side of the slide plate 11 away from the fixing groove 6 by bolts.
