Description
Technical Field
The utility model relates to a processing furniture technical field especially relates to a two interior cold hole boring cutters.
Background
The existing small hole boring cutter is mostly of an outer cooling type or a single inner cooling hole type, the diameter of a hole in small hole boring is small, cooling liquid does not work completely in the machining process of the outer cooling type boring cutter, the general cooling liquid of the boring cutter of the single cooling hole acts on a cutter point through the cooling hole, but the general diameter of the cooling hole is 1mm-1.5mm, the flow of the cooling liquid sprayed out through the cooling hole is generally small, the cooling effect is general, and the effect of discharging cutting chips is general.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a smear metal discharge effect and cooling effect are good two interior cold hole boring cutters.
In order to achieve the purpose, the utility model provides a double inner-cooling hole boring cutter, which comprises a boring cutter body, wherein the boring cutter body comprises a cutter head and a cutter handle;
two cooling channels are preset in the boring cutter body, the first cooling channel is communicated with the head end of the cutter head and the tail end of the cutter handle, one end of the second cooling channel is close to the cutter head, and the other end of the second cooling channel is communicated with the tail end of the cutter handle.
Preferably, the diameter of the section of the cutter head is smaller than that of the section of the cutter handle, so that a fall surface is formed between the connecting end surfaces of the cutter handle and the cutter head;
the second cooling channel is communicated with the fall surface and the bottom surface of the cutter handle.
Preferably, a diversion trench is preset on the side wall of the cutter head; one end of the diversion trench is communicated with the second cooling channel, and the other end of the diversion trench is close to the processing head of the tool bit.
Preferably, the boring cutter body is integrally cast and molded.
Preferably, the hole diameters of the two cooling channels are both 0.9 mm.
Compared with the prior art, the utility model has the advantages that: the double inner-cooling-hole boring cutter of the utility model is preset with two cooling channels, the first cooling channel is communicated with the head end of the cutter head and the tail end of the cutter handle, one end of the second cooling channel is close to the cutter head, and the other end is communicated with the tail end of the cutter handle; the liquid sprayed out through the first cooling channel is sprayed to the surface of the workpiece, and the liquid sprayed out through the second cooling channel is guided to the position of the machining head of the cutter through the guide groove, so that the accurate positioning and cooling of the cutter and the machined part by the cooling liquid are ensured, and the cooling effect of the machining cutter is ensured; in addition, set up 0.9 mm's cooling channel, it is littleer than traditional cooling channel aperture, increased the jet pressure of coolant liquid to make the metal fillings in the cooling channel can spout, can not make the cooling channel block up.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be further described below.
As shown in fig. 1 and 2, the utility model provides a double inner-cooling hole boring cutter, which comprises a boring cutter body 1, wherein the boring cutter body 1 comprises a cutter head 11 and a cutter handle 12;
two cooling channels are preset in the boring cutter body 1, the first cooling channel 2 is communicated with the head end of the cutter head 11 and the tail end of the cutter handle 12, one end of the second cooling channel 3 is arranged close to the cutter head 11, and the other end of the second cooling channel is communicated with the tail end of the cutter handle 12.
In the embodiment, the diameter of the section of the tool bit 11 is smaller than that of the section of the tool shank 12, so that a drop surface is formed between the connecting end surfaces of the tool shank 12 and the tool bit 11;
the second cooling channel 3 communicates the fall surface with the bottom surface of the shank 12.
In the embodiment, a diversion trench 4 is preset on the side wall of the cutter head 11; one end of the diversion trench 4 is communicated with the second cooling channel 3, and the other end of the diversion trench 4 is arranged close to the processing head of the tool bit 11.
In the present embodiment, the boring tool body 1 is integrally cast.
In this example, the hole diameters of both cooling channels are 0.9 mm.
In this embodiment, the double inner-cooling-hole boring tool of the present invention has two cooling channels in advance, the first cooling channel 2 communicates with the head end of the tool bit 11 and the tail end of the tool shank 12, one end of the second cooling channel 3 is disposed near the tool bit 11, and the other end communicates with the tail end of the tool shank 12; the liquid sprayed out through the first cooling channel 2 is sprayed to the surface of a workpiece, and the liquid sprayed out through the second cooling channel 3 is guided to the position of a machining head of the cutter through the guide groove 4, so that the accurate positioning and cooling of the cutter and a machined part by the cooling liquid are ensured, and the cooling effect of the machining cutter is ensured; in addition, set up 0.9 mm's cooling channel, it is littleer than traditional cooling channel aperture, increased the jet pressure of coolant liquid to make the metal fillings in the cooling channel can spout, can not make the cooling channel block up.
The above description is only for the preferred embodiment of the present invention, and does not limit the present invention. Any technical personnel who belongs to the technical field, in the scope that does not deviate from the technical scheme of the utility model, to the technical scheme and the technical content that the utility model discloses expose do the change such as the equivalent replacement of any form or modification, all belong to the content that does not break away from the technical scheme of the utility model, still belong to within the scope of protection of the utility model.
