When processing larger workpieces, the generated residues and chips are easy to fall on the track, hindering the movement of the gantry, and for some brittle workpieces, the residues are easy to splash and injure people, and the scattered residues will also increase the difficulty of cleaning.

DETAILED DESCRIPTION

[0016] The technical solution of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention.

The lower ends of the columns 11 are correspondingly installed on the corresponding guide rails 3 and can be moved and positioned along the guide rails 3. The overall operation design structure of the entire gantry frame can move horizontally along the Y axis, mainly for large-volume workpieces to be processed;

[0018] Two protective components 2 are symmetrically arranged on both sides of the machine tool table 6. The protective components 2 are mainly composed of a bottom plate 201, a side plate 202 fixed to the outer side of the upper plate surface of the bottom plate 201, and two end plates 203 respectively fixed to the two ends of the upper plate surface of the bottom plate 201. The two protective components 2 surround most of the space around the machine tool table 6, thereby preventing the splashing and scattering of the processing residue;

[0019] The lower plate surface of the bottom plate 201 is slidably mounted on the corresponding guide rail 3, which covers and protects the guide rail 3, maintains the cleanliness of the guide rail 3, and prevents residual materials from falling on the guide rail 3, resulting in obstruction of operation; according to needs, the number of guide rails 3 under each bottom plate 201 is set to two side by side to ensure the smoothness and accuracy of operation; the bottom end of the column 11 is fixed to the upper plate surface of the bottom plate 201 of the corresponding protective component 2, and a main protective area is formed between the column 11 and an end plate 203 of the protective component 2 corresponding to the CNC machining spindle. The CNC machining spindle is generally installed on the crossbeam 1 by hanging it off-center. By 11 is fixed on the protection component 2 and moved and positioned together, which can increase the support span and prevent the gantry structure from tipping over; according to needs, the length of the main protection area is greater than the length of the machine tool table 6 to ensure a larger protection range; the upper plate surface of the bottom plate 201 corresponding to the main protection area is a slope surface with high outside and low inside, which increases the structural strength of the bottom plate 201 and facilitates the collection of residual materials. Two support members 4 with horizontal upper surfaces are fixed at both ends of the slope surface, and a first bearing mesh plate 12 is connected between the upper parts of the two support members 4. The first bearing mesh plate 12 can facilitate people standing and storing items, and is also convenient for residual materials and water stains to leak down.

[0020] When the frame structure of the CNC gantry of the utility model is implemented, when the three-dimensional movement of the machining spindle is controlled to perform CNC machining, the scattered residual materials generated by the machining can be blocked and collected by the protective component 2, and the residual materials will not leak out or even fall on the guide rail 3 to interfere with the operation and movement of the frame. Embodiment 2:

[0021] Generally, the ground between the table plate 6 of a large machine tool and the protective component 2 is provided with a groove 7 for collecting processing residues. Therefore, on the basis of the first embodiment, the design support member 4 includes two triangular support plates with a side-by-side gap. A second bearing mesh plate 5 is provided above the first bearing mesh plate 12. Both ends of the lower plate surface of the second bearing mesh plate 5 are provided with slide rails. The slide rails are clamped between the two triangular support plates of the corresponding support member 4 and can be moved and positioned along the gap between the two triangular support plates. By pulling the second bearing mesh plate 5 to the top of the groove 7, it is used as an extended platform. Embodiment three:

[0022] On the basis of Example 1, a secondary protection area is formed between the column 11 and the other end plate 203 of the corresponding protection component 2, and the plate surface of the side plate 202 is fixed with a ventilation main pipe 8 along the longitudinal direction of the machine tool table 6. The pipe body of the ventilation main pipe 8 is provided with a plurality of blowing branches 9 with corresponding slopes at intervals along the axial direction. One end of the ventilation main pipe 8 is closed, and an air source device 10 for supplying air to the other end of the ventilation main pipe 8 is installed on the upper plate surface of the bottom plate 201 of the secondary protection area.
