Detailed Description

As shown in fig. 1 to 3, the utility model discloses a lathe tool, including handle of a knife 1 and tool bit 2, tool bit 2 sets up in 1 tip of handle of a knife, and tool bit 2 is provided with cutting edge 3, its characterized in that: be provided with cooling main entrance 4 in the handle of a knife 1, 4 one ends of cooling main entrance are opening 41 and with external UNICOM, one end is for extending end 42 and extend and run through handle of a knife 1 in to handle of a knife 1, cooling main entrance 4 and handle of a knife 1 towards parallel arrangement, be provided with first cooling branch passageway 5 in the handle of a knife 1, first cooling branch passageway 5 and cooling main entrance 4 UNICOM and respectively extend to handle of a knife 1 upper end and lower extreme, first cooling branch passageway 5 is a plurality of and evenly sets up in handle of a knife 1 along cooling main entrance 4, be provided with second cooling branch passageway 6 in the tool bit 2, 6 one end of second cooling branch passageway is connected with extension end 42 and is linked with cooling main entrance 4, one end extends to cutting edge 3.

By adopting the technical scheme, the cooling main channel 4 is arranged in the tool shank 1, one end of the cooling main channel 4 is provided with the opening 41 and is communicated with the outside, the other end is provided with the extension end 42 which extends into the tool shank 1 and penetrates through the tool shank 1, the cooling main channel 4 and the tool shank 1 are arranged in parallel, the tool bit 2 is provided with the second cooling branch channel 6, one end of the second cooling branch channel 6 is connected with the extension end 42 and is communicated with the cooling main channel 4, and the other end of the second cooling branch channel extends to the cutting edge 3, so that cooling liquid can be introduced into a lathe tool to cool the lathe tool and can be directly introduced to the cutting edge 3 to cool the region with the highest heat production, the mechanical property of the lathe tool is further ensured, the first cooling branch channel 5 is arranged in the tool shank 1, the first cooling branch channel 5 is communicated with the cooling main channel 4 and respectively extends to the upper end and the lower end of the tool shank 1, the first cooling branch channels 5 are a plurality of and are uniformly arranged in the cooling main channel 4, after the cooling liquid lets in handle of a knife 1, can enlarge the circulation scope in handle of a knife 1 of cooling liquid to make the cooling of cooling liquid to handle of a knife 1 more even, the cooling effect is higher.

First cooling branch passageway 5 is the multistage, including feed liquor section 51 and stock solution section 52, feed liquor section 51 and cooling main entrance way 4 UNICOM and set up towards cooling main entrance way 4 slope along opening 41 to extension end 42, stock solution section 52 set up in feed liquor section 51 tip and with feed liquor section 51 UNICOM, feed liquor section 51 is parallel with cooling main entrance way 4, the one end that feed liquor section 51 was kept away from to feed liquor section 51 is provided with recess 53, recess 53 is sunken down.

By adopting the above technical scheme, the liquid inlet section 51 is communicated with the cooling main channel 4 and is obliquely arranged towards the cooling main channel 4 along the opening 41 to the extending end 42, so that the arrangement direction of the liquid inlet section 51 is the same as the flowing-in direction of the cooling liquid, so that the cooling liquid can directly flow along the inclined direction of the first cooling branch channel 5 after flowing into the lathe tool, the flow speed of the cooling liquid is improved, further improving the cooling efficiency of the lathe tool, the liquid storage section 52 is arranged at the end part of the liquid inlet section 51 and communicated with the liquid inlet section 51, the liquid inlet section 51 is parallel to the cooling main channel 4, a groove 53 is arranged at one end of the liquid inlet section 51 far away from the liquid inlet section 51, the groove 53 is sunken downwards, when the cooling liquid flows in, the cooling liquid can be partially stored in the groove 53, thereby the cooling time of the coolant to the lathe tool is prolonged, the number of times of introducing the coolant is reduced, and the cutting efficiency of the workpiece is further improved.

The bottom wall of the cooling main channel 4 is provided with a convex strip 7, and the convex strip 7 is obliquely arranged towards the cooling main channel 4 along the opening 41 to the extending end 42.

Through adopting above-mentioned technical scheme, cooling main channel 4 diapire is provided with sand grip 7, sand grip 7 sets up towards cooling main channel 4 slope along opening 41 to extension end 42, the incline direction of this sand grip 7 is unanimous with the inlet liquid section 51 incline direction of the first cooling branch passageway 5 of upper end, back in coolant liquid gets into lathe tool, because the coolant liquid velocity of flow of injection is very fast, and block by sand grip 7 after contacting with sand grip 7, thereby in the first cooling branch passageway 5 of upper end is sputtered to along the incline direction part of sand grip 7, and then after letting in the coolant liquid, the coolant liquid can be more even to the cooling of handle of a knife 1, otherwise because the influence of gravity, the coolant liquid is the passageway of bottom earlier flowed into, just can flow into the passageway on top after treating the coolant liquid water level and rising.

The cutting edge 3 is arranged close to the bottom end of the cutter head 2, and the second cooling branch channel 6 is obliquely arranged towards the cutting edge 3.

Through adopting above-mentioned technical scheme, because cutting edge 3 is close to the setting of 2 bottoms of tool bit for second cooling branch channel 6 can the downward sloping and set up towards cutting edge 3, thereby lets in the back when the coolant liquid, can utilize the effect of gravity to make the coolant liquid can be faster let in to cutting edge 3 position, cool down the region that the heat production is the highest.

The tool bit 2 is a rectangular pyramid, and the top wall of the tool bit 2 is downwards sunken relative to the tool holder 1 to form a clearance gap 21.

Through adopting above-mentioned technical scheme, tool bit 2 is the rectangular pyramid to do benefit to the lathe tool to the piece discharge that produces when the cutting, 2 roof of tool bit are sunken downwards relative handle of a knife 1 and are formed clearance breach 21, thereby can avoid the lathe tool to bump with being processed the work piece in the cutting process.

The knife handle 1 and the knife head 2 are integrally arranged.

Through adopting above-mentioned technical scheme, handle of a knife 1 and 2 integrative settings of tool bit to avoid producing the vibration and influencing tool bit 2's life and machining precision between handle of a knife 1 and the tool bit 2.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
