Description

Saddle beam structure

technical field

The utility model relates to a saddle beam structure used in processing equipment, in particular to a saddle beam structure suitable for gantry processing centers, which belongs to the innovative technology of the saddle beam structure.

Background technique

The crossbeam is the main support of processing equipment such as machine tools, and the ram and spindle components are installed on the saddle, which has a great influence on the performance of the entire machine tool. The traditional sliding saddle beam structure is that the sliding saddle is installed on one side of the beam, and the headstock is in a cantilever structure, and the overturning moment generated by its gravity causes the main shaft to move backward. In addition, the installation of the saddle at different positions of the beam will result in different sinking deformations at different positions of the beam. Theoretically, when the saddle is installed in the middle of the crossbeam, the amount of downward movement and backward movement of the main shaft reaches the maximum value. In order to avoid the deformation of the beam, the stiffness of the beam is usually increased by rationally arranging the ribs, but this will make the processing of the beam more complicated and costly.

Contents of the invention

The purpose of this utility model is to overcome the above-mentioned shortcoming and provide a kind of sliding saddle beam structure. The utility model ensures that no overturning moment will be generated when the ram moves on the beam, the error of the ram in the X-axis direction is basically eliminated, the time for installing the auxiliary beam and the loading device is reduced, and the movement accuracy of the ram is improved.

The technical scheme adopted by the utility model to achieve the above-mentioned purpose is: the sliding saddle beam structure of the utility model includes a beam, a sliding saddle, and a ram, wherein the sliding saddle is installed on the Y-axis hollow chute set by the beam, and the ram is installed On the Z-axis hollow chute set by the saddle.

The saddle of the utility model is installed on the Y-axis hollow chute set by the beam, and the ram is installed on the Z-axis hollow chute set by the saddle. The utility model and the traditional saddle are installed on one side of the beam. The structure is different. Usually the ram is a cantilever structure, and its gravity and cutting force during processing will cause the beam to twist and deform. The ram of the utility model is not a cantilever structure, so that when the ram moves on the beam (Y axis), no torsional moment will be generated, so the error of the ram in the direction of the X axis is basically eliminated. The utility model reduces the time for installing the auxiliary beam and the loading device, and improves the movement precision of the ram.
