Abstract

The invention discloses a follow-up supporting tool bit device used for processing a deep hole, which comprises a tool seat and an excircle end face turning tool arranged on the tool seat and is characterized in that a tool body with a hollow structure is fixed in the front of the tool seat; the tool body with the hollow structure is in T-shaped threaded connection with a hollow boring bar; V-shaped blocks are respectively fixed at the front and rear ends of an outer cylindrical surface of the tool body with the hollow structure; 8-16 adjusting steel balls are respectively distributed in V-shaped grooves of the two V-shaped blocks; the adjusting steel balls are externally fixed by a retainer; and a radial locking nut butts against the end face of the V-shaped block and pushes the V-shaped block to move. When the V-shaped block moves, a radial force is generated to the steel ball to adjust the diameter of the outer ring of the steel ball and lead the diameter to be equal to the diameter of an inner hole processed by the excircle end face turning tool. Therefore, the device has the positioning function, the coolant flows through the hollow boring bar and the tool body with the hollow structure and is sprayed out from a coolant hole on the tool body, so that the device has the scrap discharging and cooling function in the hole of a workpiece, and can prevent the iron scraps from scratching the processed surface of the workpiece.

Description

Deep hole processing supports knife head device with servo-actuated
Technical field
The present invention relates to a kind of on lathe deep hole processing support knife head device with servo-actuated.
Background technology
Mainly adopt boring machine to come bore hole when having deep hole processing now, required boring machine costs an arm and a leg when the degree of depth in hole surpasses 1m, and because the long machining accuracy that causes of boring bar does not reach design accuracy.
Summary of the invention
The object of the present invention is to provide a kind of on lathe deep hole processing support knife head device with servo-actuated, realize to improve the precision of deep hole processing, reduce equipment cost.
The technical solution used in the present invention is: comprise tool rest, be installed in the cylindrical facing tool on the tool rest, it is characterized in that, be fixed with the cutter hub of a hollow structure in tool rest the place ahead, be threaded for the T type between the cutter hub of hollow structure and the hollow boring bar, front and back two ends at the cutter hub external cylindrical surface of hollow structure are fixed with V-block respectively, be evenly equipped with 8-16 adjusting steel ball in the V-type groove that between two V-blocks, forms, regulate the steel ball outside and fix with retainer, the locking radial nut withstands on the V-block end face and promotes V-block and moves.
Have the cooling fluid hole on the cutter hub of described hollow structure, wherein have at least the center line in a cooling fluid hole to cross point of a knife, the rear end of described hollow boring bar is connected with coolant pump, cooling fluid in the coolant pump is by the cutter hub of hollow boring bar and hollow structure, cooling fluid hole from cutter hub sprays, thereby plays the effect of chip removal and cooling.
The number of described adjusting steel ball is 12.
Advantage of the present invention: the locking radial nut withstands on the V-block end face and to promote V-block and move, when V-block moves steel ball is produced the diameter that a radial load is adjusted the steel ball outer ring, make it to equal the diameter of bore that cylindrical facing tool workpiece has been processed, thereby play the effect of location, cooling fluid is by the cutter hub of hollow boring bar and hollow structure in addition, cooling fluid hole from the cutter hub ejection at last, thus play the effect of in workpiece chip removal and cooling, can prevent that iron filings from scratching the workpiece machined surface.

Fig. 2 is servo-actuated supporting knife head device operating position structural representation;
Fig. 3 is servo-actuated supporting knife head device axle geodesic structure schematic diagram.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to accompanying drawing:
The invention will be further described below in conjunction with the drawings and specific embodiments:
Be fixed with the cutter hub 1 of a hollow structure with cylindrical pin with internal thread 11 and hexagon socket cap head screw 12 in the place ahead of tool rest 10; For the T type is threaded, cylindrical facing tool 9 usefulness hexagon socket cap head screws 13 are installed on the tool rest 10 between the cutter hub 1 of hollow structure and the hollow boring bar 15.
Front and back two ends on the external cylindrical surface of the cutter hub 1 of hollow structure are fixed with V-block 3 and 7 by cylinder end clamping fixed screw 6 respectively, be evenly equipped with 12 adjusting steel balls 5 in the V-type groove that between two V-blocks, forms, it is fixing with retainer 4 to regulate steel ball 5 outsides, and locking radial nut 2 withstands on and promotes V-block on the V-block end face and move.
On the cutter hub of hollow structure, have cooling fluid hole 8, wherein have at least the center line in a hole to cross point of a knife, the rear end of described hollow boring bar 15 is connected with coolant pump, cooling fluid is by the cutter hub of hollow boring bar and hollow structure, ejection the cooling fluid hole 8 from cutter hub at last, thus play effect to chip removal and cooling in the hole of workpiece 14.
