(2) workpiece need to move back and forth repeatedly, can just cut out screw thread, therefore the single workpiece required time of completion is longer, production Efficiency is low.

(3) this traditional screw thread cuts device, can only process shallower screw thread, can not fabricate out pitch it is wider, Deeper screw thread.

Utility model content

The purpose of this utility model is to improve the shortcomings that above-mentioned existing, there is provided a kind of cut processing cutter and tool rest, makes it Workpiece can be more rapidly cut, processes deeper, more accurately screw thread.

For the above-mentioned purpose, the utility model provides a kind of cut processing cutter, comprising：

One cutterhead, the cutter disc groups set multiple blade bearings, multiple bumping posts；And

Multiple blades, the blade are provided with a perforation, pass through the perforation by a lock member, blade is locked in into cutterhead On, and support the blade and schedule blade bearing and bumping post.

Foregoing cut processing cutter, wherein, the blade bearing includes：

One fine adjustment screw, it runs through blade bearing；

One sliding block, it is trimmed off screw and supported calmly, by rotary fine adjustment screw, can make the slider displacement；

The blade supports and schedules the sliding block and bumping post.

Foregoing cut processing cutter, wherein, the cutterhead also includes：

Multiple grooves, it is arranged between blade bearing and bumping post；

Multiple blade fixed columns, it is arranged in groove, and can be along groove displacement；

The blade is locked in blade fixed column by lock member, enables the blade to along groove displacement；

The bumping post is set to eccentric screw, by eccentric rotary, make blade anyway displacement, it is fixed all to be supported by bumping post.

Foregoing cut processing cutter, wherein, the cut processing cutter also includes：

Multiple limited blocks, it is mounted on the cutterhead, limits blade displacement amount.

The utility model also provides a kind of tool rest, and it includes foregoing cut processing cutter；

One cutter chuck holder adapted, the cutterhead are locked on the cutter chuck holder adapted；

One tool rest platform, it is for assembling the cutter chuck holder adapted；

One actuator, it rotates cutter chuck holder adapted for the cutter chuck holder adapted that links.

The beneficial effects of the utility model：If a cutterhead that can be rotated at a high speed, the cutter disc groups set multiple blade bearings and multiple Bumping post；And multiple blades, the blade are provided with a perforation, pass through the perforation by a lock member, blade is locked in into cutterhead On, and support the blade and schedule blade bearing and bumping post.By the high speed rotary head around cylindrical work eccentric rotary, reach To deeper, more accurate screw thread is cut out on workpiece the effect of (as shown in Figure 3).

Embodiment

Referring to Fig. 4, setting a cutterhead 10 that can be rotated at a high speed, 10 groups of the cutterhead sets multiple blade bearings 11 and multiple bumping posts 12；And multiple blades 13, the blade 13 are provided with a perforation 130, the perforation 130 are passed through by a lock member 14, by blade 13 are locked on cutterhead 10, and support the blade 13 and schedule blade bearing 11 and bumping post 12.Blade 13 passes through blade bearing 11 and bumping post 12 support calmly, avoid the operationally displacement of blade 13.

Second embodiment, blade bearing 11 run through blade bearing 11 comprising a fine adjustment screw 15；One sliding block 16, is trimmed off screw 15 To calmly, by rotary fine adjustment screw 15, the displacement of sliding block 16 can be made；The blade 13 supports and schedules the sliding block 16 and bumping post 12.The knife Disk 10 further includes：Multiple grooves 17, the groove 17 are arranged between blade bearing 11 and bumping post 12；Multiple blade fixed columns 18, set In in groove 17, and can be along the displacement of groove 17；The blade 13 is locked in blade fixed column 18 by lock member 14, makes blade 13 Also can be along the displacement of groove 17；The bumping post 12 is set to eccentric screw, by eccentric rotary, make blade 13 anyway displacement, all may be used It is fixed to be supported by bumping post 12；Multiple limited blocks 19, the cutterhead 10 is mounted on, limits the displacement of blade 13.

According to said structure, following effect, advantage can be obtained：

(1) referring to Fig. 5, the utility model processing mode schematic diagram, because cutterhead 10 is provided with multi-disc blade 13, cutterhead 10 is fast Speed is rotated simultaneously around the rotation of workpiece 2 surrounding eccentric, workpiece 2 is only needed single process, you can deeper, more accurately screw thread, greatly Width improving production efficiency.

(2) because the sliding block 16 of blade bearing 11 can be trimmed off the adjustment position of screw 15, therefore various sizes of blade can be housed.Change Speech on same cutterhead, can group set various sizes of blade.

(3) referring to Fig. 6, the utility model blade position adjusts schematic diagram, after blade 13 is locked in blade fixed column 18, Can be along the displacement of groove 17, when blade 13 is toward during 11 direction displacement of blade bearing, the knife edge is also displaced outwardly, and can process larger-diameter work Part.In other words, same cutterhead and blade, because blade position can adjust, therefore machinable workpiece size is wider.

Fig. 7, Fig. 8 are referred to, it is three-dimensional exploded view, the combination stereogram that cutterhead 10 is assembled to a tool rest 20, the tool rest Include a cutter chuck holder adapted 21 for locking cutterhead 10；One tool rest platform 22, for assembling the cutter chuck holder adapted 21；One actuator 23, should for linkage Cutter chuck holder adapted 21, cutter chuck holder adapted 21 is set to rotate at a high speed.

In summary, the utility model reaches on workpiece by the cutterhead of high speed rotation around workpiece eccentric rotary Cut out deeper, more accurately screw thread；Adjusted by the sliding block of blade bearing, make the same machinable workpiece size of cutterhead and blade It is wider, there is splendid practical effect.
