Description
Technical field
The utility model belongs to metal working tool class technical field, and in particular to be it is a kind of compact-sized, design is closed
Reason, and process arc groove very easily crank-type swing boring cutter.
Background technique
Boring cutter is one kind of cutting tool for boring, is mainly used for processing arc-shaped curved surface；Do not allow for existing most of boring cutter structure
Quick detachable maintenance, overall structure are difficult to replace after tool wear.
Summary of the invention
The purpose of this utility model is the deficiency for the above technology, provides a kind of compact-sized, and processing arc groove is very
Convenient crank-type swings boring cutter.
The utility model is achieved through the following technical solutions: crank-type swings boring cutter, it is characterised in that: is by cutter
Pedestal, upper cover are mounted on the pull rod composition that the knife of cutter base intracavity specifically, with knife specifically connects；The upper cover side wall
It is provided with the rectangular short slot of upper cover, the side wall of cutter pedestal is also equipped with the rectangular short slot of pedestal, and the rectangular short slot of the upper cover and bottom
The rectangular short slot size of seat is corresponding to be arranged.
The knife specifically includes outer housing, the left and right bearing for being mounted on outer housing two sides, is mounted in outer housing simultaneously
Protrude outer housing outside cutter head, be connected curved bar together with the lower end of cutter head；A plane section is arranged in the side of outer housing, and should
The upper end of cutter head is mounted at the surface of the plane section.
The upper cover is fastened on cutter pedestal by screw rod, and one of pull rod protrudes into the interior intracavitary and knife of cutter pedestal
Curved bar particularly is connected together.
Left and right bearing, outer housing and the cutter head constitutes a monolithic, and pull rod is flexible to drive curved bar movement, and cutter head is in song
Make arcuate oscillating motion under the drive of bar.
The beneficial effects of the utility model embodiment is: compared with prior art, the utility model knife is especially by screw
It is mounted on the inner cavity of cutter pedestal, and cutter head stretches out, cutter head makees arcuate oscillating motion under the drive of curved bar, and structure is simple, tears open
It unloads assembling and maintenance is very convenient.
Detailed description of the invention
The utility model is described in detail with reference to the accompanying drawing.
Fig. 1 is the utility model decomposition diagram.
Fig. 2 is the utility model integral installation schematic diagram.

Specific embodiment
As shown in Figure 1 to Figure 3, crank-type swings boring cutter, is by cutter pedestal 2, upper cover 4, is mounted on 2 inner cavity of cutter pedestal
The pull rod 1 that 202 knife specific 3 and knife specific 3 connect forms；4 side wall of upper cover is provided with the rectangular short slot 401 of upper cover,
The side wall of cutter pedestal 2 is also equipped with the rectangular short slot 201 of pedestal, and the rectangular short slot 401 of the upper cover and the rectangular short slot 201 of pedestal
Size is corresponding to be arranged, and upper cover 4 is locked on cutter pedestal 2 by hexagon socket head cap screw, and the rectangular short slot 401 of upper cover
It aligns and installs with the rectangular short slot 201 of pedestal, constitute a whole square groove.
As shown in figure 3, the knife specific 3 includes outer housing 305, the left and right bearing for being mounted on 305 two sides of outer housing
(306,303) are mounted in outer housing 305 and protrude cutter head 302 outside outer housing 305, are connected one with the lower end of cutter head 302
The curved bar 301 risen；A plane section 304 is arranged in the side of outer housing 305, and the upper end of the cutter head 302 is mounted in the plane section
At 304 surface, after knife is specifically mounted on the inner cavity 202 of cutter pedestal 2, plane section 304 just exposes out of whole square groove,
Stretch out cutter head 302 outer convenient for swing converted products cambered surface.
The upper cover 4 is fastened on cutter pedestal 2 by hexagon socket head cap screw, and one of pull rod 1 protrudes into cutter pedestal 2
It is connected together with the curved bar 301 on knife specific 3 in inner cavity 202, i.e., the mounting groove 101 that is arranged of pull rod 1 just can be with
It is screwed curved bar 301.
Left and right bearing (306,303), outer housing 305 and the cutter head 302 constitutes a monolithic, and pull rod 1 is flexible to be driven
Curved bar 301 moves, and cutter head 302 makees arcuate oscillating motion under the drive of curved bar 301, so that the easily arcwall face of converted products, special
It is not the arcwall face in bearing block.
