Description

A gantry milling machine with movable columns and beams

technical field

The utility model belongs to the technical field of mechanical processing equipment, in particular to a gantry milling machine with movable columns and beams.

Background technique

The general structure of the gantry milling machine is shown in Figure 3. The fixed handle of the column is connected to the middle position on both sides of the bed, the fixed handle of the beam is connected to the column, the saddle moves along the Y axis on the beam, and the ram is on the saddle. Moving along the Z axis, the table moves along the X axis on the bed. Affected by this structure, the range of machining workpieces will be limited to a certain extent.

There are also some gantry milling machines with movable columns or movable beams, but this kind of movable gantry milling machine sacrifices its own rigidity, resulting in low machining accuracy.

Therefore, the existing gantry milling machine cannot maximize the unification of high structural rigidity and processing convenience.

Contents of the invention

The utility model aims at the above problems and provides a high rigidity and convenient processing gantry milling machine.

In order to achieve the above purpose of the utility model, the utility model adopts the following technical scheme. The utility model includes a bed, which is characterized in that: a column base is arranged on both sides of the bed, and a column screw is provided on the column base through a column motor. The column screw is connected with the moving column; the column is provided with a beam screw through the beam motor, the beam screw is connected with the moving beam, and the moving beam is provided with a ram through a sliding saddle; the base of the column corresponds to the lower surface of the moving column The column hard rail is arranged, and the beam hard rail matched with the moving beam is arranged on the surface of the moving column.

As a preferred solution of the present utility model, a side hard rail is provided on the side of the bed corresponding to the side of the lower end of the moving column.

As another preferred solution of the present invention, the base of the upright is provided with an electromagnetic suction strip corresponding to the lower end surface of the moving upright.

Beneficial effects of the utility model: 1. High efficiency: because the utility model has a movable column and a movable crossbeam, and through the cooperative movement of the screw and the hard rail in several directions, the processing spindle is greatly improved. Rigidity enables the spindle to process a greater amount of cutting, greatly improving production efficiency.

2. High product quality: Since the utility model is equipped with an electromagnetic suction strip, it uses the working principle of electromagnetism to generate a strong magnetic field force, thereby effectively eliminating most of the processing vibration. Compared with the existing machine tools, it has the same Higher surface finish and positioning accuracy can be obtained under the same conditions, which guarantees the product quality well.

3. Reduced cost: With the substantial improvement of processing efficiency and quality, less processing time makes the cost greatly reduced.

4. Expansion of the processing range: Since the utility model has a movable column and a movable crossbeam, the processing range is obviously increased.
