Description

Technical Field

[0001] The utility model relates to the technical field of CNC lathes, in particular to a high-stability inclined rail double-spindle CNC lathe. Background Art

[0002] The inclined rail double spindle CNC lathe is a CNC lathe with a special structural design, including an inclined rail bed and double spindles; the inclined rail bed refers to the lathe bed with an inclined bed surface design, which has better rigidity and stability during the processing compared with the traditional horizontal bed. The inclined rail bed can reduce the occurrence of vibration and resonance, improve the accuracy and processing quality of the machine tool, and each spindle is equipped with an independent spindle motor and tool system, which can perform processing operations on the front and rear ends at the same time. Through the design of the double spindle, the processing time can be greatly shortened and the production efficiency can be improved; the inclined rail double spindle CNC lathe is usually also equipped with an advanced CNC system, which realizes high-precision and high-efficiency processing operations through the automated control of the processing process. In addition, some machine tools also have functions such as automatic tool changing system and automatic loading and unloading system, which further improves production efficiency; the inclined rail double spindle CNC lathe is widely used in the processing of complex parts, especially for processing tasks that require multiple processes to be performed simultaneously. It has important applications in aerospace, automobile manufacturing, mold manufacturing and other fields, and can meet the production needs of high precision and high efficiency. During processing, the existing horizontal rail lathes often generate iron chips that fly everywhere. Although some of them can fall into a special collection cabin, some of them fall directly onto the track of the slide, thereby causing track blockage and affecting the use of the entire vehicle's displacement equipment. Therefore, the operator is required to clean the iron chips on the track from time to time, which is extremely unfavorable for continuous operation and improving production efficiency. For example, "Utility Model CN210877575U A high-stability inclined rail dual-spindle CNC lathe utilizes an inwardly inclined guide rail so that the iron chips that fall on the guide rail during processing can naturally slide into the chip-dropping chamber, reducing the accumulation of iron chips on the guide rail and facilitating cleaning; at the same time, the special structure of the upper and lower clamping of the saddle plate and the ball matching makes the movement of the slide smoother and more stable, thereby improving processing stability." For the above-mentioned problems, there may already be technical means to solve them in the prior art, but this case intends to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above purpose, the utility model is implemented through the following technical solutions: a high-stability inclined rail dual-spindle CNC lathe, comprising: a lathe base, a lathe shell and a negative pressure debris collection tank, the lathe shell is installed on the lathe base, the lathe base is provided with the negative pressure debris collection tank, the lathe shell is installed with a self-cleaning inclined rail processing structure, and the negative pressure debris collection tank is installed with a self-circulating chip cleaning component;

[0004] The self-cleaning inclined track processing structure includes: a pair of extended tracks, a plurality of track coupling slide beads, a pair of side covering running slide blocks, a pair of locking cover plates, a pair of locking bolts, a pair of driving threaded rods, a series gear box, a displacement motor, a pair of displacement electric slides, a pair of practical operation bases, a hydraulic processing chuck and a composite load-bearing turret;

[0006] It should be noted that, in the above, after the workpiece is fixed by the hydraulic machining chuck, the displacement motor on the lathe shell is driven, so that the tandem gearbox drives a pair of driving threaded rods to rotate, thereby causing a pair of side covering running slides to move in relative reverse directions, and a number of track coupling slide beads are wrapped between a pair of side covering running slides and a pair of extension rails, and are covered and fixed by locking covering plates and locking bolts. In summary, it can be concluded that after a pair of side covering running slides slide close to each other along a pair of extension rails until they stop at a suitable position, a pair of displacement electric slides can support a pair of practical bases for operation. Alignment allows the hydraulic machining chuck to carry the workpiece and the composite load-bearing turret for pre-machining position calibration, after which the workpiece can be deep-processed on the lathe. The negative pressure chip collection groove opened on the lathe base can rely on the self-circulating chip cleaning component to generate negative pressure, and suck the processed debris into the negative pressure chip collection groove. At the same time, the self-circulating chip cleaning component can also continuously remove dust and chips from the processing area to prevent debris from blocking the extended track, causing displacement jamming and affecting the processing accuracy.

[0009] It should be noted that, in the above, the debris sucked by the negative pressure during processing falls into the negative pressure debris collecting tank, and the negative pressure liquid-gas dual-purpose motor can generate negative pressure, and the air in the negative pressure debris collecting tank is transferred to the liquid-gas dual-purpose pipe through the negative pressure air guide duct, and then sprayed to the workpiece position through the central groove in the seat and several chip removal spray pipes, so that the debris processed on the workpiece falls into the negative pressure debris collecting tank through the negative pressure. The above process can put the cleaning liquid into the negative pressure debris collecting tank, and make several chip removal spray pipes spray the cleaning liquid, so that the lathe can adapt to a wider processing range and save a lot of production resources.

It has the following beneficial effects: compared with the prior art, the high-stability inclined rail dual-spindle CNC lathe has the following beneficial effects: the machining debris generated by the traditional lathe during machining is easy to block the track, so that the machining accuracy during fine machining will produce errors due to the blockage of the track, thereby affecting the machining stability. The lathe uses a self-cleaning inclined track machining structure so that the side covering running slider can carry the hydraulic machining chuck with the composite bearing turret at the same time, and the debris of the machining workpiece will not block the gap on the extended track. The debris will fall into the negative pressure debris collection groove along the inclined extended track due to gravity. At the same time, combined with the self-circulating chip cleaning component, the debris will not block the track while the workpiece is being machined, thereby affecting the machining accuracy due to the sliding jam of the side covering running slider, greatly improving the stability of the CNC lathe.
