Description

Vertical lathe separated tool holder for bearing flange of 5 megawatt wind generating set gearbox

Technical Field

The utility model relates to a vertical lathe separated tool holder for a bearing flange of a gear box of a 5 megawatt wind generating set.

Background

The existing vertical lathe tool holder (the purpose is to clamp 40 x 40 lathe tool rods to perform turning on a workpiece) is heavy, 90kg of the existing vertical lathe tool holder is heavy, manual movement is difficult, and replacement and clamping are inconvenient. In addition, the interior design is not reasonable (the inner edge is right-angled, easy to crack and needs repair welding, as shown in fig. 1), and the inner edge is easy to crack when processing harder materials or cutting amount is large. The service life is about 6 months, and the replacement is required frequently. After damage, the cost of replacement is high. About 0.9 ten thousand yuan/piece.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provide the vertical lathe separated type tool holder of the bearing flange of the gear box of the 5 megawatt wind generating set, the weight is reduced by 45kg, and the replacement and the clamping are more convenient than before; the internal design is changed, and the cracking is not easy to occur when harder materials are processed or the cutting amount is larger. Has been used for 8 months without abnormality, and has a life expectancy of 3 years. After the damage, only need to change middle and lower part can, 0.36 ten thousand yuan/one. The cost is reduced.

In order to achieve the purpose, the technical scheme of the utility model is to design a vertical lathe separation type cutter holder of a 5 megawatt wind generating set gear box bearing flange, which comprises a cutter holder upper part and a cutter holder lower part which are arranged in a separation mode, wherein the cutter holder upper part and the cutter holder lower part are provided with a plug-in structure, the plug-in structure comprises a convex block arranged on the cutter holder upper part or the cutter holder lower part and a groove arranged on the cutter holder lower part or the cutter holder upper part and matched with the convex block, the bottom edge of the groove is provided with a fillet for bearing large torque and preventing cracking, the cutter holder upper part is integrally provided with a connecting cylinder connected with a vertical lathe cutter holder, the cutter holder lower part is provided with a groove for clamping a turning tool rod to perform turning on a workpiece, and the bottom edge of the groove is provided with a fillet.

The further technical proposal is that the upper part of the tool holder is detachably connected with the lower part of the tool holder.

The further technical proposal is that the upper part of the tool holder is detachably connected with the lower part of the tool holder through a bolt or a stud connecting piece.

Further technical scheme does, grafting structure is including setting up at cutter holder upper portion or the lug of cutter holder lower part and setting up in the cutter holder lower part or the cutter holder upper portion recess that matches with aforementioned lug, and the tank bottom edge of recess is equipped with the coating, and the coating forms and is used for bearing the fillet that big moment of torsion, prevent the fracture, and the coating is the TiCN coating. Thus, after the coating layer is worn or cracked (of course, the possibility of cracking is low), the coating layer can be recoated and continue to play a role in protection.

The utility model has the advantages and beneficial effects that: after the coating layer is worn or cracked (of course, the possibility of cracking is small), the coating layer can be recoated and continue to play a role in protection. The weight is reduced by 45kg, and the replacement and the clamping are more convenient than before; the internal design is changed, and the cracking is not easy to occur when harder materials are processed or the cutting amount is larger. Has been used for 8 months without abnormality, and has a life expectancy of 3 years. After the damage, only need to change middle and lower part can, 0.36 ten thousand yuan/one. The cost is reduced.

Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

The first embodiment is as follows:

as shown in fig. 2 to 3, the utility model relates to a vertical lathe separated type tool holder of a bearing flange of a gear box of a 5 megawatt wind generating set, which comprises a tool holder upper part 1 and a tool holder lower part 2 which are arranged in a separated manner, wherein the tool holder upper part 1 and the tool holder lower part 2 are provided with an inserting structure. The plug-in structure comprises a convex block 3 arranged on the upper part 1 of the cutter holder or the lower part 2 of the cutter holder and a groove which is arranged on the lower part 2 of the cutter holder or the upper part 1 of the cutter holder and is matched with the convex block 3, and a fillet 4 which can bear large torque and prevent cracking is arranged at the bottom edge of the groove. The upper part 1 of the cutter holder is detachably connected with the lower part 2 of the cutter holder. The upper part 1 of the tool holder is detachably connected with the lower part 2 of the tool holder through a bolt or a stud connector. The upper portion 1 of the tool holder is integrally provided with a connecting cylinder 5 connected with a clamping cutter head of a vertical lathe, the lower portion 2 of the tool holder is provided with a groove 6 used for clamping a turning cutter rod to perform turning on a workpiece, and the bottom edge of the groove 6 is provided with a fillet 4.

Example two:

the difference with the first embodiment lies in that the inserting structure comprises a convex block arranged on the upper part of the tool holder or on the lower part of the tool holder and a groove arranged on the lower part of the tool holder or on the upper part of the tool holder and matched with the convex block, a coating layer is arranged on the bottom edge of the groove, the coating layer forms a fillet for bearing large torque and preventing cracking, and the coating layer is a TiCN coating.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
