Description

Technical Field

[0002] A machining center is a general-purpose numerical control machining equipment, usually used for machining parts with high precision and complex structures. There are horizontal machining centers and vertical machining centers. Even to meet the machining of different workpieces, there are vertical and horizontal compound machining centers.

[0003] For example, the Chinese patent document with the publication number CN220636944U discloses a compound gantry machining center, which includes a base component. The base component is provided with a workbench component, and a working platform for clamping the workpiece to be machined is arranged on the workbench component; on one side of the base component, there are two straight columns, and on the other side, there is an inclined column. A cross beam is fixed on the two straight columns. A left saddle component and a right saddle component are slidably arranged on the cross beam. A horizontal spindle box is fixed on the left saddle component, a vertical spindle box is fixed on the right saddle component, and an inclined spindle box is fixed on the inclined column. It realizes that a machining center can machine multiple surfaces of a workpiece. There is a cross beam arranged on the two straight columns. By arranging linear guides on the cross beam, the left saddle component and the right saddle component are slidably fixed on the cross beam. Compared with the prior art using a bracket method, the overall machining center is more stable and firm, with excellent stability. And because there are three linear guides, one of which is arranged on the top surface of the cross beam, it can provide supporting forces for the left saddle component and the right saddle component from three points, absorb and relieve the acting force generated during the machining of the spindle box, greatly improve the stability during machining, have high safety, and long service life.

[0004] In the technical solution disclosed in the above patent document, multiple spindles can separately machine the workpiece. When one spindle is machining, the remaining spindles are usually in a stationary state, and it is convenient to change the tool for the unprocessed spindle, and generally, this spindle is in a state without a tool installed. Therefore, the workpiece being machined will generate flying chips and cutting fluid, and there is a possibility that the cutting fluid and flying chips will enter the spindle hole. Therefore, when the cutting tool is inserted into the spindle, problems such as tool eccentricity will occur, reducing the accuracy of the tool; even the problem of damaging the spindle hole will occur.
