Description

A moving column machining center

technical field

The utility model relates to the technical field of machining centers, in particular to a moving column machining center.

Background technique

At present, there are mainly vertical and horizontal machining centers on the market. The traditional structure of vertical machining centers is to place the long stroke (X axis) above the machine tool and the short stroke (Y axis) below. This structure has the disadvantage of processing large workpieces. When the worktable moves to one end, the center of gravity of the workpiece deviates to one side, and the deviation from the Y-axis driving position is large, which will easily cause abnormal wear of the Y-axis guide rail, and ultimately reduce the service life of the machine tool, and the above-mentioned guide rail between the Y-axis and X-axis is hard. Rail structure, the structure has low casting yield, complex processing procedures, complex assembly procedures and poor durability of machine tools; the processing technology of large parts of horizontal machining centers is complicated, the precision requirements for the processing machine are high, and the assembly technology is complicated. Due to different structures, the technical level of assembly personnel is required, which leads to long production cycle and high price of horizontal machining center; while the existing moving column machining center has a large load capacity and poor chip removal effect.

Utility model content

The technical problem to be solved by the utility model is to provide a moving column machining center with redistribution of X-axis and Y-axis travel, which can improve the service life of the machining center, has light bed weight and good chip removal effect.

In order to achieve the above object, the utility model provides the following technical solutions: a moving column machining center, including a base, an X-axis movement unit, a Y-axis movement unit, a Z-axis movement unit and a bed, and the X-axis movement unit is fixed On the base, the X-axis motion unit includes the X-axis motion screw and the X-axis linear guide rail, the X-axis motion screw and the X-axis linear guide rail are installed on the base, and the Y-axis motion unit includes the Y-axis motion screw, the Y-axis The linear guide rail and the Y-axis motion slider seat, the Y-axis motion screw and the Y-axis linear guide rail are installed on the Y-axis motion slider seat, the Y-axis motion slider seat is set on the X-axis motion unit, and the bed is set on On the Y-axis motion unit, the Z-axis motion unit is installed on the bed, and the Z-axis motion unit includes a Z-axis motion screw, a Z-axis linear guide rail and a moving column structure.

Preferably, the stroke of the X-axis motion unit is longer than that of the Y-axis motion unit.

Preferably, some chip guide grooves are arranged on the base, and there are reinforcing ribs connecting the chip guide grooves and the base.

Preferably, the linear guides are all heavy-duty linear guides.

Preferably, hollow feature holes are arranged on the bed.

The beneficial effect of adopting the above technical solution is: the moving column machining center of the utility model structure, the moving column structure can be moved to any limit position, the position of the center of gravity is on the same line as the driving position, and the force of each guide rail is uniform, without It will be subject to abnormal wear and tear. Setting some chip guide grooves on the base can remove waste chips well. The reinforcement ribs are set to ensure the strength and rigidity of the base. The use of linear guide rails can improve the yield of base castings. The linear guide rails are installed facing the castings. The requirements are low, the processing process becomes simple, and the assembly process is also simple. There is no need to scrape the guide rail. Because the load-bearing guide rail is a linear guide rail, there is no wear and tear, so the service life of the machine tool can be greatly improved. Arranging hollow holes on the bed can reduce the weight of the bed , to reduce the load on the machine tool.
