Description

A kind of face lathe

Technical field

The utility model relates to the lathe technical field, especially relates to a kind of face lathe.

Background technology

In machining, often run into, external diameter reaches Φ 3000mm, length 3000～5000mm, the long tube type workpiece of the major diameter of weight below 30 tons needs processing.Satisfy the processing of this type workpiece, need adopt the knife rest tactical diameter to reach the heavy horizontal lathe of Φ 3000mm.And general knife rest tactical diameter excessively reaches the heavy horizontal lathe of Φ 3000; Because the restriction of laterally moving the total kilometres deficiency of knife rest; Its maximum lathe bed tactical diameter often will reach Φ 3500～4000mm, and the specified load-bearing of existing this lathe is all more than 100 tons.

Because the long tube type workpiece weight of being processed all is no more than 30 tons, not only can be because of " low load with strong power " waste device resource; Also can cause processing cost to raise and reduce or lose competitiveness.The machined unit that does not more also have this heavy horizontal lathe as for contracting this type processing business, must drop into the high fund of a stroke count volume and purchase heavy horizontal lathe and bring bigger burden to enterprise.

The utility model content

The utility model technical problem to be solved provides a kind of face lathe, its objective is the laterally mobile total kilometres that improve knife rest, makes the less lathe of specified load-bearing, can the long tube type workpiece of well processed major diameter.

In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of face lathe, comprise bedplate, servomotor, main spindle box, tailstock, knife rest, cross slide, planker, and the output shaft of main spindle box is provided with chuck; Knife rest is located on the cross slide; Cross slide slides and is located on the planker, on bedplate, is provided with to be used for the tailstock guide that tailstock slides, and described bedplate is provided with the knife rest bed ways vertical with tailstock guide; Slide on the knife rest bed ways and be provided with the knife rest lathe bed, described planker is located on the knife rest lathe bed.

Described bedplate is provided with and drives the hydraulic cylinder that the knife rest lathe bed slides along the knife rest bed ways.

Described knife rest bed ways are evenly spaced four guide rails.

After the utility model adopts such structure; Have the following advantages: can traversing moving knife rest lathe bed owing between bedplate and planker, be provided with; The total kilometres that laterally move of knife rest are strengthened; Thereby make the less face lathe of specified load-bearing reach Φ 3000mm by good processing external diameter, length 3000～5000mm, the long tube type workpiece of the major diameter of weight below 30 tons.Need not to adopt specified load-bearing that existing lathe bed tactical diameter reaches Φ 3500～4000mm all at the heavy horizontal lathe more than 100 tons.Avoid the wasting of resources, processing cost is low, and this lathe cost is low, can not bring big fund obligation to enterprise.

Below will combine accompanying drawing and embodiment, the utility model will be carried out comparatively detailed explanation.

The specific embodiment

Contrast accompanying drawing below,, the specific embodiment of the utility model is done further detailed explanation through description to preferred embodiment.

As depicted in figs. 1 and 2; Face lathe; Comprise bedplate 1, on bedplate 1 one ends, be provided with the servomotor fixed mount, on the servomotor fixed mount, be installed with servomotor 7; The output shaft of servomotor 7 connects with the power shaft of main spindle box 5 on being fixedly installed on bedplate 1, and the output shaft of main spindle box 5 is provided with chuck 6.On bedplate 1, be provided with the tailstock guide 8 that is used for tailstock 2 slips, tailstock is slidingly arranged on the tailstock guide.In order to guarantee the tailstock stability in when work, tailstock guide 8 is for being arranged on two guide rails that have on the bedplate 1.

In order to realize the purpose of the utility model; On bedplate 1, be provided with the knife rest bed ways 9 vertical with tailstock guide 8; On knife rest bed ways 9, slide and be provided with knife rest lathe bed 10; Slide on knife rest lathe bed 10 upper edges and the perpendicular direction of knife rest bed ways and be provided with planker 12, on planker 12 upper edge knife rest bed ways directions, sliding is provided with cross slide 3, and knife rest 4 is located on the cross slide 3.

Further, on bedplate 1, be provided with the hydraulic cylinder 11 that driving knife rest lathe bed slides along the knife rest bed ways.Also be provided with pumping plant and the hydraulic tube and the control valve of supporting hydraulic cylinder in addition.In electric, the numerical control of lathe, servo drive system, set up the knife rest lathe bed and move hydraulic-driven, control section, realize moving on the knife rest bed ways through Driven by Hydraulic Cylinder knife rest lathe bed, that improves knife rest laterally moves total kilometres.

More stable for the knife rest lathe bed is moved on the knife rest bed ways, its knife rest bed ways are evenly spaced four guide rails.

As shown in Figure 3, utilize the utility model face lathe processing small diameter workpiece 13, be 1250mm or the littler workpiece of diameter like the diameter D1 that processes small diameter workpiece.When the stroke of cross slide is not enough, can move to the spindle centerline direction is parallel through Driven by Hydraulic Cylinder knife rest lathe bed, to guarantee cross slide enough strokes are arranged, guarantee that promptly the knife rest on the cross slide has enough strokes.

As shown in Figure 4, utilize the utility model face lathe processing large-diameter workpiece 14, be 3000mm like the diameter D2 that processes large-diameter workpiece.When large-diameter workpiece and the knife rest of processing have interference, can be through Driven by Hydraulic Cylinder knife rest lathe bed to moving away from the spindle centerline direction is parallel, the knife rest on the assurance cross slide has enough strokes, makes the knife rest maximum rotating diameter reach 3000mm.The maximum laterally mobile total kilometres of the knife rest of this face lathe are knife rest lathe bed stroke and cross slide stroke sum, thereby make the less face lathe of specified load-bearing also can process the long tube type workpiece of major diameter.

The Specifeca tion speeification of the utility model face lathe is: the maximum swing diameter of work is 3000mm; Crossing the knife rest maximum rotating diameter is 3000mm; Maximum length of workpiece is 5000mm; Maximum workpiece load-bearing is 32 tons between chuck, tailstock thimble; The chuck torque capacity is 80KN.m; The maximum cutting force of single-tool holder is 90KN; The speed of mainshaft is 0.8～133.3r/min; Diameter of chuck is 3000mm.The maximum laterally mobile total kilometres of the knife rest of this face lathe are knife rest lathe bed stroke 550mm+ cross slide stroke 550mm=1100mm, have significantly improved the laterally mobile total kilometres of knife rest.

The face lathe of the utility model heavy horizontal lathe identical with respect to tactical diameter when the long tube of processing major diameter type workpiece is the same.Therefore, it is low that this face lathe has operating cost, avoids the advantage of the wasting of resources.This lathe cost is low, can not bring big fund obligation to enterprise.In addition, this face lathe can also be processed the disc type work of somewhat larger in diameter in 3000mm.

Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the design of the utility model and the improvement of the various unsubstantialities that technical scheme is carried out; Or the design of the utility model and technical scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
