Abstract

The utility model relates to a position variable multi-cut milling flat machine card knife tool comprising a knife carriage, knife blocks, and a mandrel. The utility model is characterized in that the knife carriage shows ring shape with two adjacent layers of which of upper layer is the working layer while the lower layer is the supporting layer, the knife blocks of which the number is more than one are symmetrically positioned on the surface of the knife carriage on the two or more inside-out circumferences of which the outer circumference radius is the width of one knife block larger than that of the inner circumference, the surfaces of the knife carriage in front of each knife block are make oblique plane in front of which a chip removal break is made along the circumference, the knife carriage is fixed on the middle of the mandrel in front of which a ring shape guide frame is arranged, a plurality of guide rollers are provided homogeneously on the side panel of the guide frame. The utility model has the advantages of that the knife blocks are capable of moving and avoiding abrasion, and entitle the knife tool long durability, the surfaces of the knife carriage in front of each knife block are make oblique plane so that the knife tool has good clipping performance, the arrange of the guide frame improves the processing accuracy, the guide rollers decrease the abrasion between the knife tool and the processing piece.

Description

Indexable multitool milling flat machine swaging clamp tool

Technical field: the utility model relates to a kind of indexable multitool milling flat machine swaging clamp tool.

Background technology: at present, in machining, boring or the system of the milling vertical plane adjacent with endoporus generally use whole counterbit (belonging to the low speed cutter), or hilted broadsword processing, are difficult to increase work efficiency.Shortcoming is: cutter life is short, easy to wear, and cutter manufacturing cost height, cycle are long, the machine mill frequently, the scrappage height, cutting speed is low etc.

Summary of the invention: the purpose of this utility model is the indexable multitool milling flat machine swaging clamp tool that a kind of throw away is provided at the shortcoming of existing cutter.

The purpose of this utility model is realized by following mode:

The utility model comprises knife rest, the cutter piece, mandrel, it is characterized in that: knife rest is last, following two-layer annular, the upper strata is a working lining, lower floor is a supporting layer, the cutter piece is more than one, be arranged on symmetrically on two or more circumference from outside to inside of knife rest upper surface, the radius of excircle is than the width of the big cutter piece of radius of inner periphery, knife rest surface in each cutter piece the place ahead is made into the inclined-plane, and make the chip removal breach at the front end edge circumference on inclined-plane, knife rest is fixed on the middle part of mandrel, is provided with the annular leading truck in the front portion of mandrel, is provided with guide roller on the leading truck sidewall equably.

The utility model has the advantages that: adopt the indexable throw away of standard moulding cutter piece, cutter life is long; The cutting of multitool symmetry, working angles is steady, and cutting width is more than two times of hilted broadsword, the stock-removing efficiency height; The knife rest surface in cutter piece the place ahead is made into the inclined-plane, and gripping performance is good; The setting of leading truck improves machining accuracy, because the effect of guide roller reduces cutter and workpiece hole wall frictional force.

Description of drawings: Fig. 1 is a structural representation of the present utility model; Fig. 2 is Fig. 1 right view; Fig. 3 is an A-A portion cutaway view among Fig. 2; Fig. 4 is a schematic perspective view of the present utility model.

The specific embodiment: with reference to accompanying drawing, the utility model comprises knife rest 1, cutter piece 2, mandrel 5, knife rest 1 is last, following two-layer annular, the upper strata is a working lining, lower floor is a supporting layer, on, down two-layerly fix with taper pin, cutter piece 2 adopts cubic type standard machine swaging clamp piece, cutter piece 2 is (concrete quantity is decided according to the diameter of workpiece to be machined and the specification in hole) more than, be arranged on symmetrically knife rest 1 upper surface in, on outer two circumference, each cutter piece 2 usefulness pressure knife block 3 is pressed on the knife rest 1, be provided with pad edge bearing 11 in the inboard of each cutter piece 2, be used for making cutter piece 2 location, the radius of excircle is than the width of the big cutter piece of radius of inner periphery, knife rest surface in each cutter piece 2 the place ahead is made into the inclined-plane, and make chip removal breach 8 at the front end edge circumference on inclined-plane, knife rest 1 usefulness key 6 is fixed on the middle part of mandrel 5, is provided with annular leading truck 7 in the front portion of mandrel 5, leading truck 7 usefulness mandrel locknuts 9 are fixing with mandrel 5, are provided with guide roller 4 equably on leading truck 7 sidewalls.

The utility model is applicable to be processed the vertical plane adjacent with endoporus of the workpiece that endoporus is arranged, during use, the bare terminal end of mandrel is contained on the main shaft of boring machine or milling machine, an end that is provided with leading truck is put in the endoporus of workpiece, can be processed the vertical plane adjacent of workpiece with endoporus.

Claims
