Description

Efficient machining fixtures around the column

technical field

The utility model relates to a processing fixture, in particular to a highly efficient processing fixture around a column.

Background technique

The machine tool column is an important structural part of the machine tool, which plays a role in the up and down movement and support of the machine tool. It mainly supports the spindle box and satisfies the Z-direction movement of the spindle. The design form of double-column frame structure is generally used, and the large and medium-sized mobile columns are fixed on the sliding seat; because the column is an important part connecting the bed, the spindle and the tool magazine, its design must be paid attention to. For the spindle , The correct installation of the column has a non-negligible effect on the processing of qualified parts by the machining center, and the installation of the column is mainly reflected in its perpendicularity to the workbench.

In the existing machine tool column, as shown in Figure 2, it is a structural schematic diagram of an existing column 20, on which there are two parallel left ladder guide rails 21 and right ladder guide rails 22, between the guide rails there is also a column 20 When processing the column 20, the left step guide rail 21 and the right step guide rail 22 need to be used for positioning and installation, and the external side baffles are required for shape adjustment. The error is measured by a micrometer, and the operator When the casting (column 20) is clamped, a slight contact with the steel block will cause the casting to shift and fall easily, which will cause hidden danger to the safety of the operator. Due to the machining interference of the side baffle, the casting clamping is biased to one side of the workbench, so two clamping and four grabbing coordinates are required when machining the four sides of the casting. Novice operators need to be trained for a long time before they can process and are prone to errors during operation. It takes nearly 8 hours to process a casting, which is inefficient and the overall effect is not good.

Accordingly, the utility model proposes a fixture for efficient processing around the column.
