[0046] The specific content and implementation of the present invention will be further described below in conjunction with the accompanying drawings.
[0047] The rail clamping structure is mainly used for positioning and clamping the sawed end of the rail before sawing: the positioning operation mainly adjusts the posture of the sawed end of the rail so that the longitudinal axis of the sawed end of the rail is aligned with the sawing unit The sawing plane before rotation (rotation angle is 0°) is vertical to ensure accurate sawing angle; the clamping operation is mainly to keep the saw end of the rail stable during the sawing process to ensure the quality of the section and the stability of the sawing angle. Refer to the scheme adopted for the positioning and clamping of the rail Figure 1c , left and right positioning and clamping adopts four-point force, among which Fx1 is opposite to Fx3, Fx2 is opposite to Fx4, up and down positioning and clamping adopts three-point for...
