Description

Technical Field

[0001] The utility model relates to the technical field of gantry processing, in particular to a double-spindle gantry center. Background Art

[0002] A gantry machining center is a machining center in which the axis of the spindle Z-axis is set perpendicular to the worktable. The overall structure is a large-scale machining center with a portal structure frame composed of double columns and a top beam. There is also a crossbeam in the middle of the double columns. It is particularly suitable for machining large workpieces and workpieces with complex shapes. Machining centers usually include vertical machining centers and horizontal machining centers. Among them, horizontal machining centers are suitable for mass production of products with complex part shapes and high precision requirements, especially the processing of boxes and complex structural parts.

[0003] After searching, it was found that a dual-spindle gantry drilling and tapping center was disclosed in a utility model patent with Chinese publication number CN212634957U. The dual-spindle gantry drilling and tapping center in the utility model patent is driven to the required processing station by the drilling and tapping spindle through a cross slide and a Z-direction screw assembly arranged on the cross slide. The length of the workbench can be adjusted according to the length of the workpiece to be processed.

[0023] The spindle cooling structure 5 includes a cooling water tank 501, a water pump 502, a first connecting pipe 503, a second connecting pipe 504, a manifold 505 and a waste liquid tank 506. The back of the column plate 3 is fixedly connected with the cooling water tank 501, and the top of the cooling water tank 501 is fixedly installed with a water pump 502. The water pump 502 pumps out the cooling water and sends it to the first telescopic hose and the second telescopic hose respectively. The back of the slide frame 401 is fixedly connected with the first connecting pipe 503, and the cantilever 402 is fixedly connected with the second telescopic hose. A second connecting pipe 504 is fixedly connected to the back, and the No. 1 telescopic hose and the No. 2 telescopic hose deliver cooling water to the first connecting pipe 503 and the second connecting pipe 504 respectively. A manifold 505 is fixedly connected to the top of the gantry machine tool 1, and a plurality of inclined manifold grooves are provided on the manifold 505 to facilitate pouring waste liquid into the waste liquid tank box 506. A waste liquid tank box 506 is fixedly connected to the rear side of the gantry machine tool 1, and the filter plate in the waste liquid tank box 506 is used to filter the waste residue and waste liquid sewage.

[0024] When implementing, follow these steps:

[0025] 1) First, the motor cylinder of the electro-hydraulic push rod 405 drives the piston push rod to drive the slide frame 401 to move up and down on the column plate 3 to adjust the distance between the first spindle 403 and the second spindle 404 and the workpiece;

[0026] 2) Then the workpiece is processed at high speed by using the first spindle 403 and the second spindle 404, and the water pump 502 draws the cooling water from the cooling water tank 501 and delivers the cooling water to the first telescopic hose and the second telescopic hose through the second water delivery pipe;

[0027] 3) The cooling water is then sent into the first connecting pipe 503 and the second connecting pipe 504 by the first telescopic hose and the second telescopic hose respectively, so as to spray and cool down the first spindle 403 and the second spindle 404;

[0028] 4) Finally, the waste liquid is introduced into the waste liquid tank box 506 by using the confluence groove of the confluence plate 505, and the waste residue and sewage are separated by the filter plate in the waste liquid tank box 506.

[0029] according to Figure 1As shown, the right side of the slide frame 401 is slidably connected to the slide rail groove, and the electro-hydraulic push rod 405 uses the electric motor as the power source, outputs pressure oil through the bidirectional gear pump, and is controlled by the oil circuit integrated block to the oil cylinder to realize the reciprocating motion of the piston push rod, thereby driving the slide frame 401 to move up and down, and adjusting the distance between the first spindle 403, the second spindle 404 and the workpiece.

[0030] according to Figure 1 As shown, the previous gantry machining center has a single spindle structure and can only process one side of the workpiece, with low efficiency and precision. By designing the first spindle 403 and the second spindle 404 to be on the same axis, they can be processed simultaneously and the concentricity of the inner and outer holes can be guaranteed. The cantilever 402 is fixed on the slide frame 401, the first spindle 403 is installed in the slide frame 401, and the second spindle 404 is fixed on the cantilever 402. When the worktable 2 rotates, it drives the workpiece to rotate, so that drilling and tapping operations can be performed at any angle of the workpiece.

[0031] according to Figure 1 and Figure 3 As shown, a water inlet pipe is connected to the left side of the cooling water tank 501 to facilitate water replenishment operations. The water pump 502 draws out the cooling water through the No. 1 water pipe and uses the No. 2 water pipe to send the cooling water to the No. 1 telescopic hose and the No. 2 telescopic hose respectively. The design of the No. 1 telescopic hose and the No. 2 telescopic hose can facilitate the first spindle 403 and the second spindle 404 to move up and down with the slide frame 401.

[0032] according to Figure 1 and Figure 3 As shown, the left end of the first connecting tube 503 and the bottom of the second connecting tube 504 are fixedly connected with spray heads, and the two spray heads are respectively located directly above the first main shaft 403 and the second main shaft 404, and the two spray heads are used to spray and cool the first main shaft 403 and the second main shaft 404.

[0033] according to Figure 1 and Figure 3 As shown, the conduit plate 505 is located directly below the two sprinkler heads, and a number of conduit grooves of inclined structures are provided on the inner side of the conduit plate 505 to facilitate the introduction of waste residue and wastewater into the waste liquid tank box 506. The filter plate in the waste liquid tank box 506 is used to separate the waste residue and sewage, and then the wastewater is discharged from the drain pipe on the left side of the waste liquid tank box 506.

[0034] In summary, the dual-spindle gantry center first uses the electro-hydraulic push rod 405 to drive the slide frame 401, so that the first spindle 403 and the second spindle 404 on the slide frame 401 can move up and down to adjust the working distance with the workpiece on the workbench 2. When the first spindle 403 and the second spindle 404 process the workpiece at high speed, the cooling water in the cooling water tank 501 is pumped out by the water pump 502 and enters the first connecting pipe 503 and the second connecting pipe 504 through the first telescopic hose and the second telescopic hose, and then the first connecting pipe 503 and the second connecting pipe 504 are connected. The spray heads on the tube 503 and the second connecting tube 504 directly spray the first spindle 403 and the second spindle 404, thereby achieving a cooling effect, and then the manifold 505 is used to collect the flushing waste liquid and merge it into the waste liquid tank 506, and the filter plate in the waste liquid tank 506 is used to separate the waste residue and sewage, thereby achieving the effect of waste residue separation and collection, which solves the problem that the spindle structure of the dual-spindle gantry drilling and tapping center in the above-mentioned background technology lacks a cooling component, and a large amount of heat is generated during friction with the workpiece, which easily affects the workpiece processing accuracy.
