Description
Technical field
The utility model relates to a kind of multiple-cutting-edge fine boring cutter.
Background technology
Planet carrier is one of main member of planetary transmission, and planet wheel spindle or bearing are just contained on planet carrier.When planetary gear is as basic building block, it bears the maximum part of moment of face in mechanism.The structural design of planetary gear and to manufacture the load distribution between each planetary gear to such an extent as to the bearing capacity of transmission device, noise and vibration etc. have a significant impact.Boring cutter is the one of cutting tool for boring, be generally circle handle, also have larger workpiece user knife bar, the most frequently used occasion be exactly in hole machined, reaming, profiling etc.There is one or two cutting tip, be specifically designed to and roughing, semifinishing or accurately machined cutter are carried out to existing hole.Boring cutter can use on boring machine, lathe or milling machine.At present, the product sheet planet carrier different-diameter for small lot multi items unifies the processing of the many endoporus of axis, and employing is many mostly processes boring cutter, such long processing time, and efficiency is low; The axiality in each hole is difficult to be ensured well, time simultaneously sometimes because of part complexity, the more machine cutter holder that is subject to again of cutter is used to hold quantitative limitation and to have to many machine toolings and have impact on production, at this moment as with special non-standard cutter costly, the cycle is long, greatly increases production cost impact production.
Utility model content
The technical problems to be solved in the utility model is the defect overcoming prior art, provides a kind of multiple-cutting-edge fine boring cutter.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of multiple-cutting-edge fine boring cutter of the utility model, it comprises several boring heads, each described boring head is provided with boring blade, is connected described in adjacent two between boring head by connecting rod; Internal diameter and the external diameter of some described boring heads successively decrease all successively, and the external diameter of a rear boring head is identical with the internal diameter of previous boring head; All be bolted between each described boring head and described connecting rod.
Further, described boring head is set to two, comprises the first boring head and the second boring head, and the internal diameter of described first boring head is identical with the external diameter of the second boring head; The internal diameter 2cm less of the internal diameter of described first boring head of described second boring head.
The beneficial effect that the utility model reaches is:
The utility model by corresponding boring head and connecting rod in order direct be connected with bolt and be connected to handle of a knife use; Unified standardization special purpose interface, can carry out combination by any one boring head and other boring head as required and install, simultaneously can secondary (two boring heads), three grades (two boring heads), even more multistagely combines; Can carry out the processing in several hole, be only the process time of original part simultaneously, and disposable processing is simultaneously got rid of many factors and ensured product quality.This multiple-cutting-edge fine boring cutter is not only applicable to holes sheet planet carrier, being applicable to the coaxial casing of porous by changing connecting machine tool handle of a knife simultaneously, can being suitable for the machining center of all size of each machine tool plant.Simultaneously the utility model also decreases number of changing knife and effectively reduces lathe wearing and tearing, reduces processing cost because saving the twice Ministry of worker.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for description, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.In the accompanying drawings:

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Embodiment 1
As shown in Figure 1, a kind of multiple-cutting-edge fine boring cutter of the utility model, it internal diameter comprising the first boring head 1 and the second boring head 2, first boring head 1 is identical with the external diameter of the second boring head 2; The internal diameter 2cm less of the internal diameter of the first boring head 1 of the second boring head 2; First boring head 1 and the second boring head 2 are provided with boring blade 8, are connected by head rod 3 between the first boring head 1 and the second boring head 2; All be bolted between each boring head and connecting rod.
During use, second boring head 2 is connected on head rod 3, is connected on the first boring head 1, then be connected on lathe handle of a knife 7 by third connecting rod 6, mounted cutter will be combined, be placed on vernier boring blade 8 on tool setting gauge and can be placed on lathe to corresponding size and use.
Embodiment 2
As shown in Figure 2, a kind of multiple-cutting-edge fine boring cutter of the utility model, it internal diameter comprising the first boring head 1, second boring head 2 and the 3rd boring head 4, first boring head 1 is identical with the external diameter of the second boring head 2; The internal diameter of the second boring head 2 is identical with the external diameter of the 3rd boring head 4; The internal diameter 2cm less of the internal diameter of the first boring head 1 of the second boring head 2; The internal diameter 2cm less of the internal diameter of the second boring head 2 of the 3rd boring head 4; First boring head 1, second boring head 2 and the 3rd boring head 4 are provided with blade 8; Connected by head rod 3 between first boring head 1 and the second boring head 2; Connected by the second connecting rod 5 between second boring head 2 and the 3rd boring head 4; All be bolted between each boring head and connecting rod.
The utility model by corresponding boring head and connecting rod in order direct be connected with bolt and be connected to handle of a knife use; Unified standardization special purpose interface, can carry out combination by any one boring head and other boring head as required and install, simultaneously can secondary (two boring heads), three grades (two boring heads), even more multistagely combines; Can carry out the processing in several hole, be only the process time of original part simultaneously, and disposable processing is simultaneously got rid of many factors and ensured product quality.This multiple-cutting-edge fine boring cutter is not only applicable to holes sheet planet carrier, being applicable to the coaxial casing of porous by changing connecting machine tool handle of a knife simultaneously, can being suitable for the machining center of all size of each machine tool plant.Simultaneously the utility model also decreases number of changing knife and effectively reduces lathe wearing and tearing, reduces processing cost because saving the twice Ministry of worker.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
