Abstract

The utility model relates to a tip support structure of a precise tool arrangement type numerically controlled lathe. The tip support structure comprises a bottom ring, a beam and a bearing bracket. The bottom ring is a round ring body. A plurality of stepped holes are formed between the inner circle and the outer circle of the bottom ring. The beam is integrally connected to the right end face of the bottom ring. The bearing bracket is fixed to the right end of the beam. A bearing mounting hole is formed in the bearing bracket, and the bearing mounting hole and the bottom ring are coaxially arranged. A plurality of screw holes are formed in the outer side of the bearing bracket. Due to the tip support structure, the machining capacity of the lathe is improved, the machining quality for the lathe to machine long and thin parts is improved, and the tip support structure has the advantages of being simple in structure, convenient to use and the like.

Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the actual structural representation that uses of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
The tip holder structure of the row-knife numerically controlled lathe of this precision, it comprises base ring 3.1, crossbeam 3.2 and bearing bracket stand 3.3; Described base ring 3.1 is torus, between the inner circle of base ring 3.1 and cylindrical, offer several stepped holes 3.6, on the right side of base ring 3.1, be connected with crossbeam 3.2, be fixed with bearing bracket stand 3.3 in the right part of crossbeam 3.2, on bearing bracket stand 3.3, offer bearing mounting hole 3.4, bearing mounting hole 3.4 is coaxial setting with base ring 3.1, offers several screw holes 3.5 on the bearing bracket stand 3.3 in bearing bracket stand 3.3 outsides.
The thickness of described bearing bracket stand 3.3 is greater than the thickness of base ring 3.1.
On the bearing bracket stand 3.3 in bearing bracket stand 3.3 outsides, be the screw hole 3.5 evenly offering more than three or three.
Between the inner circle of base ring 3.1 and cylindrical, be the stepped hole 3.6 evenly offering more than three or three.
When use, the left side of base ring 3.1 and front-end of spindle lid 2 are fitted, be arranged on front-end of spindle lid 2 by four stepped holes 3.6 above, described crossbeam 3.2 supports and connects base ring 3.1 and bearing bracket stand 3.3, has three screw holes 3.5 of bearings mounted bearing mounting hole 3.4 and rigid bearing lid 10 on described bearing bracket stand 3.3.
Tip holder structure of the present utility model is arranged on by screw on the front-end of spindle lid 2 of numerical control lathe, front-end of spindle lid 2 is fixed on spindle unit 1, described bearing 6, lining 7 are arranged in the bearing mounting hole 3.5 of tip holder 3, described bearing cap 10 is pressed on the outer ring of bearing 6, is connected with tip holder by screw, described top 4 put into tailstock sleeves 5 puts into bearing locking nut 8 and locks, uses simultaneously and female 9 also tightly, described top 4 with adapter 12 in collet chuck 11 coaxial.
The course of work of the present utility model is as follows: will manufacture intact all parts, as bearing 6, lining 7, tailstock sleeve 5, top 4, bearing (ball) cover 10, locking nut 8 and and female 9 correctly enter in tip holder 3 by the relation in Fig. 2, adjust precision, again the Special centre device of the row-knife numerically controlled lathe of whole precision is contained on front-end of spindle lid 2, make top 4 center line coaxial with the center line of main shaft, and be fastenedly connected screw after meeting precision, folder top workpiece, locking nut 8 and and female 9 rear wait lathe operations.
The utility model has been realized the folder one top function to slender piece processing, and the utility model has increased the ability of accurate row-knife numerically controlled lathe to slender piece processing, has improved the machining accuracy to slender piece processing.
