Description
Technical Field
The utility model relates to a cutter specifically is a quick reamer.
Background
The reamer is the instrument that is used for the bore hole, and the handle of a knife of conventional reamer is fixed on the cutter sleeve, and the cutter sleeve adopts the mode of holding tightly to realize the fixed of handle of a knife, and so, the fixed often can waste time of reamer, how can realize quick installation to the reamer, has become the problem that this company researcher urgently needed to solve.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how to realize quick installation of the reamer;
in order to achieve the purpose, the utility model is realized by the following technical scheme:
the utility model relates to a rapid reamer, which comprises a reamer handle and a reamer head;
a V-shaped notch is formed in the tool handle, one side of the V-shaped notch is an end face, and an included angle between the end face and the axis of the tool handle is an acute angle;
a knife sleeve for fixing the knife handle is arranged on the knife handle, an inclined threaded hole is formed in the knife sleeve, a bolt penetrates through the inclined threaded hole, and one end of the bolt abuts against the end face;
one side surface of the V-shaped notch is abutted to one end surface of the bolt, the central line of the inclined threaded hole is perpendicular to the end surface, when the bolt is rotated, the bolt pushes the tool shank to move towards the inner side of the tool sleeve and lock the tool shank, the other side surface of the V-shaped notch has a limiting effect, when the bolt pushes the tool shank to a corresponding position, the other side surface of the V-shaped notch is abutted to the bolt, and the bolt is limited to continue rotating.
How to discharge the cutting fluid during rotation, the utility model adopts a cutter head comprising an edge lobe and a cutter bar, one end of the cutter bar is connected with the cutter handle through a limiting block; a cutting edge is arranged on the side wall of the other end of the cutter bar, and the cutting edge is uniformly arranged on the cutter bar in a spiral shape and extends to the end part of the cutter bar; a spiral liquid discharge groove is formed between the blade lands;
the spiral blade is adopted, the boring can be better carried out, and the spiral liquid discharge groove formed between the two blades can better discharge the cutting liquid.
The utility model has the advantages that: the utility model relates to a quick reamer through setting up the oblique terminal surface to and the bolt of perpendicular to terminal surface can realize the quick installation location of reamer, the utility model discloses the structure is retrencied.

The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic view of the matching structure of the knife handle and the knife sleeve of the present invention;
FIG. 3 is a schematic view of the land configuration of the present invention;
in the figure: 1-knife handle, 2-knife head, 3-V-shaped notch, 4-end face, 5-knife sleeve, 6-bolt, 7-limiting block, 8-blade, 9-knife rod and 10-liquid discharge groove.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-2, the utility model relates to a rapid reamer, which comprises a reamer handle 1 and a reamer head 2;
a V-shaped notch 3 is formed in the tool handle 1, an end face 4 is arranged on one side of the V-shaped notch 3, and an included angle between the end face 4 and the axis of the tool handle 1 is an acute angle a;
a knife sleeve 5 used for fixing the knife handle 1 is arranged on the knife handle 1, an inclined threaded hole is formed in the knife sleeve 5, a bolt 6 penetrates through the inclined threaded hole, and one end of the bolt 6 abuts against the end face 4;
one side surface of the V-shaped notch is abutted to one end surface of the bolt, the central line of the inclined threaded hole is perpendicular to the end surface, when the bolt is rotated, the bolt pushes the tool shank to move towards the inner side of the tool sleeve and lock the tool shank, the other side surface of the V-shaped notch has a limiting effect, when the bolt pushes the tool shank to a corresponding position, the other side surface of the V-shaped notch is abutted to the bolt, and the bolt is limited to continue rotating.
As shown in fig. 3, how to discharge the cutting fluid during rotation, the utility model adopts a cutter head 2 comprising a blade 8 and a cutter bar 9, wherein one end of the cutter bar 9 is connected with a cutter handle 1 through a limiting block 7; a cutting edge 8 is arranged on the side wall of the other end of the cutter bar 9, and the cutting edge 8 is uniformly arranged on the cutter bar 9 in a spiral shape and extends to the end part of the cutter bar 9; a spiral liquid discharge groove 10 is formed between the blade lands 8;
the limiting block has the effect that the limiting block can be abutted against the end face of the cutter sleeve to prevent the reamer from being continuously fed in the cutter sleeve.
The spiral blade is adopted, the boring can be better carried out, and the spiral liquid discharge groove formed between the two blades can better discharge the cutting liquid.
The utility model relates to a quick reamer through setting up the inclined end face to and the bolt of perpendicular to terminal surface can realize the quick installation location of reamer, the utility model discloses the structure is retrencied
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
