Abstract

Clipping type boring head, a kind of heavy boring spot facing cutter of mechanical processing industry high-speed cutting.90 ° of J-type hole boring cutters are mounted on cutterhead end face along the circumferential direction in the rectangle cutter holder of equal distribution by 4-16, cutter becomes larger with cutterhead and is increased, all blades are on axial same plane, it is close to positioning stud side on cutterhead in the adjusting screw rod end face of cutter hub tail portion, rotation adjusting screw rod can arbitrarily adjust point of a knife to identical radius of machining, process diameter adjusting range up to 40mm.All cutter heads of the cutterhead are cut simultaneously, and the cutting force of receiving is equal, contrary, cancel out each other up and down, and processing efficiency is more than 10 times of hilted broadsword processing.The utility model can both use on boring machine, also can be simple using the utility model structure on the lathes such as lathe, planer-type milling machine, and tool changing is convenient, low in cost, though it is not easy to be eliminated without high-tech content.

Description

Clipping type boring head

Technical field

The utility model relates to a kind of cutter, especially a kind of clipping type boring head for roughing inner hole belongs to machine Tool process tool technical field.

Background technique

My adjustable boring tool disk filed on December 25th, 2015, there is that stable cutting is without friction, feature high in machining efficiency, But there is also processing blind hole is unable to, it is not capable of processing the following inner hole of Φ 120mm, spare adjustment cutter head quantity is too many and adjustable range Smaller, wedge form wedge form dovetail slot difficulty of processing is big, wedge-shaped oblique angle and the too high defect of fit dimension required precision.Therefore, it is necessary to this Cutterhead improves upgrading, and more applicable cutter new product is provided for boring machine.

Utility model content

The purpose of this utility model is that in view of the above shortcomings of the prior art, it is more simple to provide a kind of structure, processes nothing Difficulty, cooperation require low, low in cost, energy high-speed cutting and the novel thick borer one that can quickly adjust tool sharpening radius Clipping type boring head (see Fig. 1-Figure 11).

The utility model is achieved through the following technical solutions: a kind of clipping type boring head, including cutterhead, cutter holder, J 90 ° of hole boring cutters of type, 75 ° of hole boring cutters of J-type, adjusting screw rod, positioning pin, positioning stud and fastening bolt, characterized in that cutterhead left end Along the circumferential direction equalization is machined with size identical rectangle cutter holder 4-16, and cutter holder becomes larger with cutterhead and increased, and cutter holder top adds Work has Φ 20mm circular through hole, and one of 2mm wide through slot is processed at circular hole Down Highway, processes two on the left of the through slot of cutter holder lower part at two corners A Φ 10.2mm through-hole, through slot right side process two M10 screw holes, and through-hole is coaxial with screw hole, also can individually process cutter holder, with calmly Cutter holder is fastened on cutterhead by position pin and bolt, and cutterhead right end is boring cutter bar or taper shank structure；90 ° of hole boring cutters are in J-type, and knife bar is Cylindrical body, diameter is identical as cutter holder circular hole, and knife bar tail end face processes one M8 × 35mm screw hole；75 ° of hole boring cutters of J-type with 90 ° of J-type Hole boring cutter, in addition to blade shapes are different with tool cutting edge angle, auxiliary angle, knife bar diameter is identical with length dimension；Adjusting screw rod For M8 × 30mm, one end is cylinder of the 20 × 2mm of Φ with annular knurl, is mounted on hole boring cutter and adjusts in screw hole；Hole boring cutter is to adjust spiral shell Rod end surface is close to cutterhead positioning column side, is placed in cutter holder circular hole, point of a knife is directed at tack dial gauge, according to the scale of display Numerical value rotates adjusting screw rod, can arbitrarily adjust boring cutter radius, tightens through slot gap clamp-on tool with fastening bolt, twists simultaneously Tightly on cutterhead.For mounted hole boring cutter blade on axial same plane, radius of machining size is identical.

90 ° of hole boring cutters 4-16 (see Fig. 1, Fig. 2, Fig. 5, Fig. 6,16 rake knife installations diagram are not drawn) of equal distribution J-type on cutterhead, All cutters are cut simultaneously when processing, and the cutting force that symmetrical cutter head is born is equal, contrary, mutually support up and down Disappear.Φ 60mm inner hole can be processed in the cutterhead minimum, processes diameter adjusting range up to 40mm, overcoming adjustable boring tool disk cannot add Work blind hole is not capable of processing the following inner hole of Φ 120mm, and spare adjustment number of cutters is too many and adjustable range is smaller, wedge form wedge form dovetail slot Difficulty of processing is big, and 2 times of left sides can be improved than hilted broadsword cutting in wedge-shaped oblique angle and the too high defect of fit dimension required precision, cutting speed The right side, feed can increase 2-8 times than double-pole cutting, substantially increase processing efficiency.

When processing through-hole, 75 ° of hole boring cutters of J-type can be used.Than 90 ° boring cutter intensity of 75 ° of boring cutters are higher, and cutting ability is more preferable, More conducively chip breaking and chip removal, feed can also increase by 30% or so.

The utility model structure is simple, easy to adjust, low in cost, though it is not easy to be eliminated without high-tech content.

The utility model can both use on boring machine, and can be also used on the lathes such as lathe, planer-type milling machine

The clipping type boring head huge market demand, economic benefit and social benefit are significant, and small investment, quick, the several months That is recoverable cost.

Specific embodiment

Embodiment one

Rough bore clipping type boring head 1 (see Fig. 1, Fig. 2), 4 are mounted on cutterhead end face circumferentially side 90 ° of J-type hole boring cutters Into the rectangle cutter holder of equal distribution.Positioning stud side on cutterhead is close in the adjusting screw rod end face of cutter hub tail portion, and 4 blades exist On axial same plane, rotation adjusting screw rod can arbitrarily be adjusted cutter to identical radius of machining, process diameter adjusting range Up to 40mm.4 cutter heads of the cutterhead are cut simultaneously, and the cutting force of receiving is equal, contrary, cancel out each other up and down, are cut It cuts speed and can be improved 2 times or so than hilted broadsword cutting (cutting depth is identical), feed can be improved 4 times.

Embodiment two

Rough bore clipping type boring head 2 (see Fig. 5, Fig. 6), along the circumferential direction impartial installation 8 J types, the 90 ° of borings of cutterhead end face Hole knife is suitble to the processing above inner hole of Φ 200mm.8 cutter head simultaneous processings of the cutterhead, stable cutting, chip removal is smooth, processing efficiency It is more than 10 times of hilted broadsword processing, feed is 4 times of double-pole machining (cutting depth is identical), substantially increases processing effect Rate.
