Abstract
Machine tool chief axis fastener, is characterized in that, comprise main shaft, tight cover, inserts, friction pulley, nut and Non-return ring, friction pulley is fixed with inserts, and inserts is with inner conical surface; Be arranged with tight cover outside main shaft, tight cover outer surface is provided with male cone (strobilus masculinus) and is meshed with the inner conical surface of inserts; The lower end of tight cover is provided with screw thread and has the nut matched with it, can avoid inserts and axial displacement between tightly overlapping; Nut outer end is provided with Non-return ring, can prevent nut from getting loose; Nut, inserts and tight cover all can independently be changed, easy to maintenance, safe and reliable, reducing production cost, also without the need to offering pin hole on main shaft, not affecting the rigidity of main shaft.
Description
Technical field
The utility model relates to machine tool field, particularly relates to a kind of machine tool chief axis fastener of bench tapping machine.
Background technology
Lathe common on the market, needs expense nail on main shaft, adopts pin to connect, thus reduce the rigidity of main shaft between main shaft and friction pulley; When friction pulley needs to change, must change together with main shaft, make maintenance inconvenient, too increase the cost of maintenance.The utility model is exactly the improvement carried out to overcome the above problems.
Utility model content
The purpose of this utility model is to provide a kind of easy convenience, safe and reliable machine tool chief axis fastener.
The technical scheme that the utility model adopts for its technical problem of solution is:
Machine tool chief axis fastener, is characterized in that, comprise main shaft, tight cover, inserts, friction pulley, nut and Non-return ring, friction pulley is fixed with inserts, and inserts is with inner conical surface; Be arranged with tight cover outside main shaft, tight cover outer surface is provided with male cone (strobilus masculinus) and is meshed with the inner conical surface of inserts; The lower end of tight cover is provided with screw thread and has the nut matched with it, can avoid inserts and axial displacement between tightly overlapping; Nut outer end is provided with Non-return ring, can prevent nut from getting loose.
Tight cover is pyramidal structure.
The utility model has the advantage of:
1. adopt taper tightly to overlap setting, the parts such as nut, inserts and tight cover can independently be changed, easy to maintenance, reduce maintenance cost; Without the need to offering pin hole on main shaft, do not affect the rigidity of main shaft.
2. employ Non-return ring, can prevent nut from getting loose, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the machine tool chief axis fastener structural representation that the utility model proposes.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with diagram and specific embodiment, setting forth the utility model further.
With reference to shown in Fig. 1, this machine tool chief axis fastener comprises main shaft 1, tightly overlaps 2, inserts 3, friction pulley 4, nut 5 and Non-return ring 6, and friction pulley 4 is fixed with inserts 3, inserts 3 is with inner conical surface; Be arranged with tight cover 2 outside main shaft 1, tight cover 2 outer surfaces are provided with male cone (strobilus masculinus) and are meshed with the inner conical surface of inserts 3; The lower end of tight cover 2 is provided with screw thread and has the nut 5 matched with it, the axial displacement can avoided inserts 3 and tightly overlap between 2; Nut 5 outer end is provided with Non-return ring 6, can prevent nut 5 from getting loose.
Tight cover 2 is pyramidal structure.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
