Description

Non-fixed size sealing ring indexable boring cutter seat

Technical Field

The utility model relates to a bore sword technical field especially relates to but not fixed dimension sealing washer transposition boring blade holder.

Background

The boring cutter is one of hole machining cutters, is generally a round handle, and is also commonly used in a vertical lathe for a square cutter rod of a larger workpiece, wherein the most common occasions are inner hole machining, hole expanding, profiling and the like. But not only can process the hole in, the terminal surface excircle also can process, only used to be not so used in the past, at present in the seal ring groove processing, mostly use to customize fixed diameter groove sword or walk a mode processing of whole circle with minor diameter milling cutter, fixed diameter groove sword diameter can not be adjusted in a flexible way and the cutter wearing and tearing back tolerance can not guarantee, it is big with minor diameter milling cutter processing allowance, inefficiency and cutter easily broke.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the diameter of the groove cutter with fixed diameter can not be flexibly adjusted in the prior art, and providing an indexable boring cutter seat for a sealing ring with non-fixed size.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the indexable boring cutter holder for the sealing ring with the unfixed size comprises a cutter holder, wherein a supporting part is fixedly connected to the cutter holder, a through hole is formed in the supporting part, a rotating shaft can be inserted into the through hole, a blade is fixedly connected to the rotating shaft, a positioning mechanism is arranged on the rotating shaft, and the back of the blade is abutted to the supporting part.

Preferably, the positioning mechanism comprises a plurality of threaded holes, a connecting block and a fastening bolt, the plurality of threaded holes are formed in the rotating shaft at equal intervals on the circumference, the connecting block is fixedly connected to the supporting portion, and the fastening bolt penetrates through the connecting block and is in threaded connection with the threaded holes.

Preferably, the fastening bolt is a stainless steel bolt.

Preferably, the blade is provided with two cutting edges.

Preferably, one end of the rotating shaft, which is far away from the blade, is provided with anti-slip grains.

The utility model provides a but transposition boring blade holder of non-fixed size sealing washer, beneficial effect lies in: through rotating the pivot, the rethread plays fixed effect with fastening bolt and screw hole counter shaft, so that rotate the blade, thereby change the inclination of blade, thereby change the cutting edge of blade to the distance of main shaft, thereby when changing the blade and rotate, cut out the diameter in sealing washer groove, so that process out the sealing washer groove of different diameters, compare and need not to demolish the cutter from the main shaft before, can directly adjust the cutter diameter on the lathe, the accent sword step has been simplified, efficiency has been promoted.

Drawings

Fig. 1 is a schematic structural view of an indexable boring tool holder for a non-fixed-size seal ring according to the present invention;

fig. 2 is a perspective view of the indexable boring tool holder for the non-fixed-size seal ring of the present invention;

fig. 3 is an enlarged view of a portion a in fig. 1 of the indexable boring tool holder for the non-fixed-size seal ring according to the present invention.

In the figure: the tool apron comprises a tool apron 1, a supporting part 2, a blade 3, a rotating shaft 4, a threaded hole 5, a connecting block 6 and a fastening bolt 7.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1 to 3, the indexable boring cutter holder for a non-fixed-size seal ring comprises a cutter holder 1, wherein the cutter holder 1 is connected with a spindle, and when the spindle rotates, the cutter holder 1 is driven to rotate, so that a blade 3 rotates.

Fixedly connected with supporting part 2 on the blade holder 1 has seted up the through-hole on the supporting part 2, can peg graft in the through-hole and have pivot 4, fixedly connected with blade 3 on the pivot 4, is provided with positioning mechanism on the

pivot

4, and 3 backs of a knife blade and supporting part 2 looks butt are through adopting supporting part 2 when blade holder 1 rotates, play the effect of support to blade 3.

Positioning mechanism includes a plurality of screw holes 5, connecting block 6, fastening bolt 7, a plurality of screw holes 5 have been seted up to the circumference equidistance on the pivot 4, connecting block 6 fixed connection is on supporting part 2, fastening bolt 7 runs through connecting block 6 and screw hole 5 threaded connection, through rotating pivot 4, play fixed effect to pivot 4 with fastening bolt 7 and screw hole 5 again, so that rotate blade 3, thereby change the inclination of blade 3, thereby change the cutting edge of blade 3 to the distance of main shaft, thereby when changing blade 3 and rotating, cut out the diameter in seal groove, so that process out the seal groove of different diameters, compare and need not to demolish the cutter from the main shaft before, can directly adjust the cutter diameter on the lathe, the knife adjustment step has been simplified, and the efficiency is improved.

The fastening bolt 7 is a stainless steel bolt, and the stainless steel bolt is adopted, so that the situation that the fastening bolt is rusted due to the fact that the fastening bolt is fixed by a common bolt is avoided.

When in use, when the diameter of the seal ring groove needs to be adjusted, the inclination angle of the blade 3 is changed, so that the distance from the cutting edge of the blade 3 to the main shaft is changed, then the fastening bolt 7 is in threaded connection with the threaded hole 5, the blade 3 is fixed, and the diameter of the seal ring groove is cut when the blade 3 rotates.

Example 2

Referring to fig. 1, as another preferred embodiment of the present invention, on the basis of embodiment 1, the blade 3 is provided with two cutting edges, and by using the cutting edges, in case that one of the cutting edges is worn, the blade 3 is rotated by rotating the rotating shaft 4, and the cutting edge is replaced.

Example 3

Referring to fig. 3, as another preferred embodiment of the present invention, on the basis of embodiment 1, one end of the rotating shaft 4 away from the blade 3 is provided with anti-slip patterns, and by adopting the design of the anti-slip patterns, the friction force is increased, which is beneficial to rotating the rotating shaft 4.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
