Abstract
The invention discloses a follower rest device for a horizontal gantry lathe. The follower rest device comprises a gantry. A follower rest is installed on one side of the gantry. A follower rest seat is installed on the side surface of the gantry in a suspended way. The upper part of the follower rest seat is fixed with the gantry. A follower rest supporting device which consist of two groups of rotating handles, positioning sleeves, screws, guide columns and ejection columns is installed at the lower part of the follower rest seat in a direction perpendicular to the axis of a workpiece. The follower rest device for the horizontal gantry lathe has the advantages that not only can the range of the diameter of machined bars be increased, but also the processing stability and the machining accuracy of long shaft parts are increased, and the application scope of the lathe is increased.
Description
Technical field
The invention belongs to the Metal Cutting Machine Tool technical field, especially relate to a kind of device of the follow-rest for gantry horizontal lathe.
Background technology
In the tradition engine lathe, knife rest is fixed on little supporting plate, then little supporting plate, horizontal supporting plate, big palette are layering on bed ways again, cause maximum machining diameter on knife rest to only have half of maximum machining diameter on lathe bed slightly many, are unfavorable for the processing of thick major axis.The movable gantry type numerical control lathe occurred at present can increase processing bar diameter range, but, when the processing longaxones parts, working ability is subject to certain limitation, and its less stable has especially affected machining accuracy and the scope of application of lathe.
Summary of the invention
The objective of the invention is: for the problem of above-mentioned existence, provide a kind of longaxones parts good stability, device of the follow-rest for gantry horizontal lathe that machining accuracy is high processed.
Technical scheme of the present invention is: comprise portal frame, portal frame is arranged on two horizontal guide rails on lathe bed, and gantry feed arrangement is housed between portal frame and lathe bed, and gantry feed arrangement drives portal frame and moves along the horizontal guide rail on lathe bed; One side of portal frame is equipped with follow-rest, follow-rest comprises follow-rest seat, rotating handles, positioning sleeve, screw rod, guide pillar, fore-set, the follow-rest seat hangs the side that is arranged on portal frame, follow-rest seat top and portal frame are fixed, the bottom of follow-rest seat be equipped with on the direction perpendicular to axis of workpiece that two groups of rotating handleses, positioning sleeve, screw rod, guide pillar, fore-set form with the cutter bracing or strutting arrangement, guide pillar is by the thread connection screw rod, guide pillar is installed in the pilot hole in the follow-rest seat, rotating handles and screw rod link, and fore-set is arranged on the top of guide pillar.
Further, follow-rest seat top is arranged on portal frame by fixing pin, one group of rotating handles, positioning sleeve, screw rod, guide pillar, fore-set be arranged on workpiece above, another group rotating handles, positioning sleeve, screw rod, guide pillar, fore-set are arranged on the back of workpiece.
The invention has the beneficial effects as follows: the present invention adopts follow-rest to hang the side that is arranged on portal frame, portal frame is arranged on the guide rail above lathe bed, gantry feed arrangement drive portal frame and follow-rest are along the horizontal guide rail transverse shifting on lathe bed, portal frame moves flexibly, and the while follow-rest is followed portal frame and moved.During work, by handling rotating handles, drive bolt rotary, thereby promote guide pillar and fore-set motion, fore-set is close on workpiece.When the knife rest on portal frame is processed feeding along the axis of workpiece direction, follow-rest withstands workpiece on the rightabout of cutting force, prevents the flexural deformation that affects machining accuracy that long-axle workpieces occurs under the effect of Tool in Cutting power.The present invention had both increased the diameter range of processing bar, had strengthened again stability and the machining accuracy of processing longaxones parts, had increased the scope of application of lathe, controlled easy maintenance, and manufacture and use cost are cheap, was convenient to manufacture in batches and promote.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the internal structure schematic diagram of follow-rest part of the present invention;
Fig. 4 is the B-B cutaway view of Fig. 3.
The specific embodiment
The A-A cutaway view that is structural representation of the present invention and Fig. 2 from Fig. 1 can be found out, the present invention includes portal frame 4 and follow-rest 13, portal frame 4 is arranged on two horizontal guide rails of lathe bed 1 front and rear support wall 3, rear support wall 3 is in lathe bed 1 back, between portal frame 4 and lathe bed 1, gantry feed arrangement 9 is housed, gantry feed arrangement 9 drives portal frame 4 along the horizontal guide rail transverse shifting on lathe bed 1.Gantry of the present invention horizontal lathe mainly contains lathe bed 1, main spindle box 2, rear support wall 3, portal frame 4, knife rest 5, little supporting plate 6, tailstock 7, automatically controlled part 8, gantry feed arrangement 9, knife rack feed apparatus 10, spiral chip removal device 11, ash can 12, follow-rest 13 etc. and partly forms.Main spindle box 2 is identical with traditional lathe with the installation site of tailstock 7, and main spindle box 2 is contained in lathe bed 1 one ends, and tailstock 7 is contained on the horizontal guide rail of lathe bed 1.Portal frame 4 is arranged on the guide rail of lathe bed 1 and rear support wall 3, there is the horizontal guide rail perpendicular to the axis of workpiece direction on portal frame 4, knife rest 5 is arranged on little supporting plate 6, and little supporting plate 6 is suspended on the horizontal guide rail of portal frame 4 again, and follow-rest 13 hangs the left surface that is arranged on portal frame 4.During work, workpiece is arranged on the centre of lathe bed and portal frame and follow-rest.
From the internal structure schematic diagram of follow-rest part of the present invention and the B-B cutaway view of Fig. 4 shown in Fig. 3, can find out, one side of portal frame 4 is equipped with follow-rest 13, and follow-rest 13 mainly contains follow-rest seat 14, rotating handles 15, positioning sleeve 16, screw rod 17, guide pillar 18, fore-set 19, fixing pin 21, guider screw 22 etc. and partly forms.Follow-rest 13 hangs the left surface that is arranged on portal frame 4, the top of follow-rest seat 14 is arranged on portal frame 4 by fixing pin 21, follow-rest seat 14 following be equipped with on the direction perpendicular to perpendicular to workpiece 20 axis that two groups of rotating handleses 15, positioning sleeve 16, screw rod 17, guide pillar 18, fore-set 19 form with the cutter bracing or strutting arrangement, one group of rotating handles 15, positioning sleeve 16, screw rod 17, guide pillar 18, fore-set 19 be arranged on workpiece 20 above, another group rotating handles 15, positioning sleeve 16, screw rod 17, guide pillar 18, fore-set 19 are arranged on the back of workpiece 20.Rotating handles 15 links by pin with screw rod 17, and screw rod 17 is by positioning sleeve 16 axial restraints, and guide pillar 18 is by thread connection in screw rod 17, and guide pillar 18 is installed in the pilot hole of follow-rest seat 14.Guider screw 22 is arranged on follow-rest seat 14, and its front end heads in the gathering sill of guide pillar 18, and fore-set 19 is arranged on the top of guide pillar 18.During work, drive screw rod 17 rotations by handling rotating handles 15, thereby promote guide pillar 18 and fore-set 19 motions, fore-set 19 is close on workpiece 20.When knife rest 5 is processed feeding along workpiece 20 axis directions, follow-rest 13 withstands workpiece 20 on the rightabout of cutting force, prevents the flexural deformation that affects machining accuracy that long-axle workpieces occurs under the effect of Tool in Cutting power.
