Description

Forward and reverse rotation deep hole turning tool
Technical Field
The utility model relates to a deep hole machining cutter technical field, especially corotation reversal deep hole lathe tool.
Background
In the machining process of aviation parts, deep hole machining is often needed, the requirement on roughness is high, common forming deep hole drills and deep hole push boring cutters cannot meet the requirement, and a numerical control lathe and a deep hole turning tool are needed to machine.
However, a general deep-hole lathe tool cannot simultaneously machine the side surface and the bottom surface of a hole, the lathe tool needs to be replaced, the deep-hole lathe tool is long and heavy, the replacement is difficult once, and the deep-hole lathe tool can only be manually replaced due to being too long, and the tool needs to be manually set again after the deep-hole lathe tool is replaced, so that the problem of automatically machining a deep hole is solved.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's shortcoming, provide a corotation reversal deep hole lathe tool, can reach the side and the bottom surface of one process processing deep hole, no manual tool changing action, do not have the tool setting again and look for the coordinate. The parts are only replaced without changing the tools, and the process automation is realized.
The purpose of the utility model is realized through the following technical scheme:
the forward and reverse rotation deep hole turning tool comprises a tool handle, a tool bit, a first blade and a second blade, wherein the tool bit is arranged at the end part of one end of the tool handle, the side wall, far away from the tool handle, of the tool bit is provided with the first blade and the second blade respectively, the second blade is positioned above the first blade, the projection distance of a connecting line between the cutting edge of the second blade and the cutting edge of the first blade in the axis direction of the tool handle is a, and a is not less than 10mm and not more than 20 mm.
Furthermore, the length of the knife handle is L which is more than or equal to 1000 mm.
Further, the first blade and the second blade are respectively fixed on the cutter head through screws.
Further, the cutter head and the cutter handle are of an integrally formed structure.
Furthermore, the projection distance of a connecting line between the cutting edge of the second blade and the cutting edge of the first blade in the radial direction of the tool handle is b, and b is greater than or equal to 30mm and less than or equal to 37 mm.
The utility model has the advantages of it is following:
1. the side surface and the bottom surface of the deep hole can be machined in one process, no manual tool changing action is needed, and no tool setting and coordinate searching are needed again. The parts are only replaced without changing the tools, and the process automation is realized.
2. The utility model discloses a lathe tool can install the clamp and carry out processing on numerical control lathe, and roughness is little, accords with aviation parts machining's requirement.

Detailed Description
The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.
As shown in fig. 1 and 2, the forward and reverse rotation deep hole turning tool comprises a tool shank 1, a tool bit 2, a first blade 3 and a second blade 4, wherein the tool bit 2 is arranged at one end of the tool shank 1, the side wall of the tool bit 2, which is far away from the tool shank 1, is provided with the first blade 3 and the second blade 4, the second blade 4 is positioned above the first blade 3, the projection distance of a connecting line between the cutting edge of the second blade 4 and the cutting edge of the first blade 3 in the axial direction of the tool shank 1 is a, and a is not less than 10mm and not more than 20 mm.
Further, the length of the knife handle 1 is L, and L is larger than or equal to 1000 mm.
Furthermore, the first blade 3 and the second blade 4 are respectively fixed on the cutter head 2 through screws, so that the mounting is convenient, the cutting edge direction of the blades is adjustable, and the cutter is suitable for different processing positions.
Furthermore, the tool bit 2 and the tool handle 1 are of an integrally formed structure, so that the structural strength of the turning tool is enhanced.
Furthermore, the projection distance of a connecting line between the cutting edge of the second blade 4 and the cutting edge of the first blade 3 in the radial direction of the tool holder 1 is b, and b is greater than or equal to 30mm and less than or equal to 37 mm. Different b values can be selected according to the diameter of the bottom of the hole.
The working process of the utility model is as follows: before processing, fix handle of a knife 1 on numerical control lathe's main shaft, will replace the processing part to fix on the workstation, adopt first blade 1 to process (rough turning, finish turning) the side of deep hole, treat the side processing of deep hole and finish the back, remove second blade 2 to the opposite side of deep hole for second blade 2 is close to with the bottom surface of deep hole, and the lathe tool antiport is processed (rough turning, finish turning) the bottom surface of deep hole through second blade 2, and the tool moves back until bottom surface roughness meets the requirements. The utility model discloses a deep hole lathe tool only needs a clamping, can realize the side and the high processing of bottom surface requirement of deep hole, has reduced the inconvenience that the tool changing brought.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
