Abstract
The invention relates to a tip support structure of a precision row tool type digital-controlled lathe. The tip support structure comprises a bottom ring, a horizontal beam and a bearing frame. The bottom ring is a circular ring body. A plurality of step holes are formed between an inner circle and an outer circle of the bottom ring. The horizontal beam is integrally connected to the right end face of the bottom ring. The bearing frame is fixed at the right end portion of the horizontal beam. A bearing mounting hole is formed in the bearing frame. The bearing mounting hole and the bottom ring are arranged in a coaxial mode. A plurality of screw holes are formed in the outer side of the bearing frame. According to the tip support structure, the machining capacity of the lathe is improved, the machining quality for thin long part machining of the lathe is improved, and the tip support structure has the advantages of being simple, convenient to use and the like.

Technical field
The present invention relates to the part using on the row-knife numerically controlled lathe of a kind of precision, the tip holder structure of the row-knife numerically controlled lathe of especially a kind of precision.
Background technology
At present, accurate row-knife numerically controlled lathe cannot be realized the processing technology on folder one top, so cannot processing long and thin component.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of tip holder structure of the row-knife numerically controlled lathe of precision that can increase the working ability of lathe and improve the processing quality of machine tooling thin and long units is provided.
According to technical scheme provided by the invention, the tip holder structure of the row-knife numerically controlled lathe of described precision, it comprises base ring, crossbeam and bearing bracket stand; Described base ring is torus, between the inner circle of base ring and cylindrical, offer several stepped holes, on the right side of base ring, be connected with crossbeam, right part at crossbeam is fixed with bearing bracket stand, on bearing bracket stand, offer bearing mounting hole, bearing mounting hole is coaxial setting with base ring, on the bearing bracket stand in bearing bracket stand outside, offers several screw holes.
The thickness of described bearing bracket stand is greater than the thickness of base ring.
On the bearing bracket stand in bearing bracket stand outside, be the screw hole evenly offering more than three or three.
Between the inner circle of base ring and cylindrical, be the stepped hole evenly offering more than three or three.
The present invention has increased the working ability of lathe, has improved the processing quality of machine tooling thin and long units, and the present invention is simple in structure and convenient in use.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Fig. 2 is the actual structural representation that uses of the present invention.
The specific embodiment
Below in conjunction with specific embodiment, the invention will be further described.
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, in the right part of crossbeam 3.2, be fixed with bearing bracket stand 3.3, 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.
During use, the left side of base ring 3.1 and 2 laminatings of front-end of spindle lid, four stepped holes 3.6 by are above arranged on front-end of spindle lid 2, 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 invention is arranged on the front-end of spindle lid 2 of numerical control lathe by screw, 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, by screw, is connected with tip holder, described top 4 put into tailstock sleeves 5 puts into locking nut 8 lockings for bearing, uses and female 9 also tightly simultaneously, described top 4 with adapter 12 in collet chuck 11 coaxial.
The course of work of the present invention 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 by the relation in Fig. 2, correctly enter in tip holder 3, 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 present invention has realized the folder one top function to slender piece processing, and the present invention has increased the ability of accurate row-knife numerically controlled lathe to slender piece processing, has improved the machining accuracy to slender piece processing.
