[0002] In the cross beam processing process, the surface of the cross beam needs to be punched and milled by a machine tool. Since the cross beam is long and strip-shaped, the traditional clamps on the machine tool cannot be adapted, so special machine tool functional components and accessories need to be used on the machine tool as a cross beam processing tool.

[0003] The existing cross beam processing tool generally adopts a two-end clamping method to clamp and fix the cross beam.

Although the above clamping method can clamp and fix cross beams of different lengths, the beam body lacks clamping and limiting design, resulting in poor clamping and fixing effect of the cross beam.

After locking, as shown in Figure 9 The lifting oil cylinder 804 continues to contract, and the elastic telescopic rod 802 is completely stretched.

[0059] Through the above design, after locking, the elastic telescopic rod 802 can also be stretched to provide a downward pulling force, which improves the installation effect. At the same time, the downward pulling force and the driving of the locking block 806 to lock and unlock are driven by the lifting oil cylinder 804, so that the entire locking mechanism 8 does not need to be provided with multiple power components, and the locking block 806 does not need to be provided with a power component.
