Description

Technical Field

[0001] The utility model relates to the technical field of gantry milling machines, in particular to a guide rail of a gantry milling machine. Background Art

[0002] The circular column guide rails of existing gantry boring and milling machines mainly play a supporting role. For equipment such as gantry boring and milling machines that often move on beams, their precision is insufficient, the resistance is large, the guide rails wear quickly, and the service life is short. The commonly used linear guide rails maintain good geometric accuracy during the processing, but only focus on the load and cannot better adapt to the reverse anti-twisting force of the machine tool during processing, resulting in poor anti-twisting rigidity of the linear guide rails in actual applications. Summary of the invention

[0003] The utility model aims to solve the deficiencies of the prior art and provides a guide rail for a gantry milling machine to overcome the problems of poor anti-twisting rigidity and short service life.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0005] The lower rail is provided with an upper and a lower rail, and the lower rail is provided with an upper and a lower rail in a rotation direction of the rotation of the gear wheel.

[0006] The guide roller is connected to the top of the upper guide rail cavity of the crossbeam slider through an upper hanging plate.

[0007] The wheel axle of the guide roller is perpendicular to the tangent line of the groove wall of the spiral groove.

[0008] The supporting roller is connected above the lower guide rail cavity of the crossbeam slider through a slider extension plate.

[0009] The wheel axle of the supporting roller is perpendicular to the axis of the lower guide rail.

[0010] The upper surface of the lower guide rail is provided with a positioning groove for supporting the rolling connection of the roller.

[0011] The beneficial effect of the utility model is as follows: the utility model installs a double-layer structure of an upper guide rail and a lower guide rail, and opens a spiral groove on the surface of the upper guide rail. The guide roller is cooperatively connected with the spiral groove. The driving motor rotates to drive the upper guide rail to rotate, thereby driving the crossbeam slider to move. The crossbeam slider is supported on the lower guide rail through the supporting roller. The support and drive of the crossbeam slider are dispersed on the two guide rails, which avoids the boring and milling device from generating too strong anti-twisting rigidity when moving, thereby reducing the wear of the guide rail and extending the service life.

[0018] The guide roller 10 is connected to the top of the upper guide rail cavity 13 of the beam slider 8 through the upper hanging plate 9. The wheel axle of the guide roller 10 is perpendicular to the groove wall tangent of the spiral groove 6, so that the guide roller 10 can be embedded in the spiral groove 6 and roll.

[0019] The support roller 11 is connected above the lower guide rail cavity 15 of the crossbeam slider 8 through a slider extension plate 14 .

[0020] The wheel axle of the supporting roller 11 is perpendicular to the axis of the lower guide rail 3, ensuring that the supporting roller 11 can perform linear motion along the lower guide rail.
