Detailed description of the invention

Known, for the plant equipment such as lathe of horizontal type structure, if there is main moving direction, such as, there are bed ways Structure, the direction of bed ways is the first dimension, can be generally defined as X-axis, or the length direction of lathe, at horizontal plane Interior perpendicular direction is generally fore-and-aft direction, and the usually second dimension, is being Y-axis defined in Digit Control Machine Tool, and front is general It it is side, operator place.Correspondingly, if there is the third dimension with horizontal plane, then Z axis it is commonly defined as.

See a kind of laser cutting machine handling equipment as shown in Figure of description 1-5, with the form of skeleton diagram in figure Reflect its architecture, mainly release its basic structure bright and principle, be attainable in the range of its technical problem defined.

Above-mentioned handling equipment, its basic structure includes:

Frame 1, for horizontal type structure, it is generally the case that frame 1 is it is generally required to reliable and stable, and is relatively fixed, for some Vibrating more violent lathe, frame 1 is typically required and is arranged on mill floor by such as foundation bolt etc..Self is shaken Dynamic when not affecting machining accuracy, frame 1 relies on its bigger deadweight and relatively low center of gravity to be placed on precalculated position, workshop.

Laser cutting typically will not produce the biggest vibration, thus can be found in Figure of description 4, and frame configures four Base 16 or runners, can be directly placed at the precalculated position in workshop, and leveling work platforms.

Frame is basis support body, as it was previously stated, work platforms typically requires leveling, adds meeting the cutting of template workpiece Work, for workpiece when carrying out cutting processing, waste material may stay on the table, and product falls, it is also possible to waste material falls, and produces Product are stayed on work platforms.What this utility model related generally to stay the workpiece portion of work platforms takes off problem.

Comparatively speaking, in frame designs, it is generally acknowledged the base part of plant equipment and be configured to one with base part The main casing etc. of part such as electromotor be referred to as frame, and in analysis of mechanism, relatively fixed part be referred to as frame, right This, the technical staff of mechanical field should be expressly understood.

Relatively, frame 1 as shown in Figure 1 design for frame in frame, frame is provided with work platforms, work Platform can be assemblied in frame 1 by releasable connection part, it would however also be possible to employ kinematic pair is arranged on frame 1, different to adapt to Application.

Frame arranges frame body guide rail, the bed ways being analogous on lathe, it is provided that primary standard.

Routinely, have material-receiving device, drawer 14 as shown in Figure 3 at work platforms, can extract out, to transport Under material.

Meanwhile, as it was previously stated, be analogous to machine tool guideway, the direction represented by frame body guide rail is primary standard, thus at frame body On guide rail cloth set direction, side, work platforms place is process side, and opposite side is dress discharge side.

The mounting of critical piece is used the first portal frame 2 and the second portal frame 4 as shown in Figure 1, and two portal frames are joined Put on the frame body guide rail at work platforms；Portal frame is more applied to crane technical field, referred to as straddle truck, accordingly Support body is referred to as hoisting gantry frame, and its base structure is to operate in each column on two tracks, across two column tops Crossbeam, lays suspender on crossbeam.

It practice, portal frame is not in the proportionate relationship of column Yu crossbeam, although in laser cutting technique field seldom Use the concept of portal frame, but be the most generally provided with two guide rails at present in laser cutting technique field, and set on two guide rails Put the crossbeam supported on two columns, and two columns, crossbeam arranges laser cutting machine, substantially falls within gantry frame structure.

Comparatively speaking, the column applying portal frame in laser cutting technique field is shorter, and essence constitutes frame body rail Slide block on road, i.e. realizes the mobile guide of portal frame by coordinating of frame body track and portal frame.
