Abstract

The utility model discloses a spiral cut formed inner milling cutter with variable-position machine clamp, which comprises a cutter head, a cutter holder, an eccentric pin, a cutter blade, an adjusting cushion block and a wedged pressed compact. The spiral cut formed inner milling cutter with variable-position machine clamp comprises the cutter head 1, the cutter holder 2, the eccentric pin 3, the cutter blade 4, the adjusting cushion block 7 and the wedged pressed compact 8, wherein, the cutter head 1 is provided with at least one group of cutter holder 2; the cutter holder 2 is pressed tightly inside a cutter holder chute respectively from the side face and the top side of the cutter holder 2 by the wedged pressed compact 8 and a bolt 6; the radial position of the cutter holder 2 is limited by the eccentric pin 3; the adjusting cushion block 7 is arranged between the cutter holder 2 and a lateral locating face of the cutter holder chute; the cutter blade 4 is fixedly mounted on the cutter holder 2 by a plum-blossom bolt. The spiral cut formed inner milling cutter with variable-position machine clamp is suitable for processing various spiral chute shapes, can mill and cut a spiral formed chute in one step, and has high machining efficiency, large machining allowance, good precision preservation, variable-position cutter blade, long service life of the cutter, simple structure, and convenient assembly and disassembly.

Description

Milling cutter in the moulding of machine clip variable-position helicla flute
Technical field
The utility model relates to a kind of milling cutter, milling cutter in the moulding of particularly a kind of machine clip variable-position helicla flute.
Technical background
At present, the processing of domestic screw spiral forming tank mainly contains dual mode, a kind of is to adopt the processing of car preface, and the shortcoming of this processing mode is that working (machining) efficiency is low, and precision is difficult to guarantee, will just can finish the processing of spiral forming groove through several procedures, tool category is many, and management difficulty is big.Another kind is to adopt to mill preface processing, and present employed moulding spiral cut milling cutter substantially all is a welded type, and the cutter hub utilization rate is low, sharpening to workman's specification requirement the cutter uniformity behind the high and mill poor, machining accuracy and cutting ability all are difficult to guarantee.
Summary of the invention
The purpose of this utility model is in order to have overcome the shortcomings and deficiencies of existing structure and technology, milling cutter in the moulding of a kind of machine clip variable-position helicla flute to be provided, to have improved screw spiral forming tank working (machining) efficiency and machining accuracy and energy-saving and cost-reducing.
The technical solution of the utility model is as follows: milling cutter in the moulding of machine clip variable-position helicla flute, comprise cutterhead, cutter holder, cam pin, blade, adjust cushion block and wedge press block, cutter holder is arranged on the cutterhead regularly, wedge press block and screw are pressed on it cutter holder groove from cutter holder side and end face respectively, its fastening principle is that wedge press block is pressed on it insert groove from the cutter holder side screwing under the drive of screw, be provided with oval counterbore on the cutter holder top, the oval counterbore that screw passes on the cutter holder is pressed on the cutter holder groove from the cutter holder top with cutter holder, the cutter head end of cutter holder points to the center of circle, the cutter holder radial position is limited by cam pin, regulate cam pin and can adjust the radial position of cutter holder, be provided with the adjustment cushion block between cutter holder and cutter holder groove side-locating face, the thickness that changes cushion block can change the point of a knife height to adapt to the cutting requirement, blade is installed on the cutter holder, is fixed by the plum blossom screw.
Described blade is the special molding indexable insert tip, throw away tip, the blade of installing on each cutter holder can be identical also can be different, the shaping blades on each cutter holder overlaps the spiral forming face that cuts mutually.
The beneficial effects of the utility model are as follows: can disposablely process the screw spiral forming tank, precision keeps, and chipping allowance is big, the working (machining) efficiency height only needs replacing blade or cutter holder just can process the helicla flute of nearly all grooved, cuts brisk, shock resistance is good, and is simple in structure, easy to loading and unloading.
Description of drawings
The front view of milling cutter in the moulding of Fig. 1 machine clip variable-position helicla flute
The partial view of milling cutter in the moulding of Fig. 2 machine clip variable-position helicla flute
Among the figure: the 1-cutterhead, the 2-cutter holder, the 3-cam pin, the 4-blade, 5-plum blossom screw, the 6-screw, 7-adjusts cushion block, 8-wedge press block.
The specific embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, as Fig. 1 and Fig. 2, milling cutter in the moulding of machine clip variable-position helicla flute, by cutterhead 1, cutter holder 2, cam pin 3, blade 4, adjust cushion block 7 and wedge press block 8 compositions, one group of cutter holder 2 is installed on the cutterhead 1 at least, from cutter holder 2 sides and end face cutter holder 2 is pressed on the cutter holder groove respectively with wedge press block 8 and screw 6, the cutter head end of cutter holder 2 points to the center of circle, cutter holder 2 radial positions are by cam pin 3 restrictions, be provided with between cutter holder 2 and cutter holder groove side-locating face and adjust cushion block 7, blade 4 is fixedly mounted on the cutter holder 2 by plum blossom screw 5.
Blade 4 is the special molding indexable insert tip, throw away tip.
Shown in Fig. 1 and Fig. 2 blade two kinds of specifications are arranged is chamfering blade and R circular arc blade, wherein having what install on the cutter holder is chamfering blade, what install on all the other cutter holders is R circular arc blade, and the shaping blades on four cutter holders overlaps the spiral forming face that cuts mutually.
