Summary of the invention
The utility model provides a kind of simple in structure, large gear numerical control saw-tooth setting machine that working (machining) efficiency is high for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of large gear numerical control saw-tooth setting machine, comprise lathe bed and the numerical control indexing table that is installed on the lathe bed, the outside of described numerical control indexing table is coaxially arranged with the supporting adn fixing device that is packed in the large gear on the ground with it; Left and right symmetrically is provided with two saw heads that structure is identical on the described numerical control indexing table, one of them saw head comprises that the X that is fixed on the index table is to line slideway, described X is equipped with the saddle that can drive this guide rail movement of lower edge at driving mechanism on line slideway, affixed Y is to line slideway on the described saddle, described Y is equipped with the column that can drive this guide rail movement of lower edge at driving mechanism on line slideway, the affixed Z in the outside of described column is to line slideway, described Z is equipped with the slide plate that can drive this guide rail movement of lower edge at driving mechanism on line slideway, be connected with band saw on the described slide plate.
The utility model can also adopt following technical measures:
Above-mentioned large gear numerical control saw-tooth setting machine, be characterized in: the supporting adn fixing device of described large gear comprises and is evenly distributed on around the numerical control indexing table, is packed at least three workpiece support columns on the ground, a work support all is installed on each workpiece support column, and large gear is packed on the work support by claw.
Advantage and the good effect that the utlity model has are: do not rotate by workpiece, with band saw the between cog metal of gear is become the piece excision, the sawing seam can be less than 1mm, and required cutting power only has several kilowatts, and stock-removing efficiency improves more than 10 times than generating; Secondly, machine tool structure does not need the complicated driving-chain of traditional generating, and simple in structure, cost is low; The 3rd, on machine tool structure, adopt the fixed innovative idea of work piece in the process, large gear is processed, no longer need to drive the large-scale turntable that workpiece rotates, but but process tool is contained on the less numerical control rotating platform of precision indexing positioning and locking, thereby realized that the weight of this saw-tooth setting machine has only the part of traditional large-scale gear hobbing machine, gear shapping machine with a less machine tooling large gear.In a word the utility model be a kind of efficiently, large gear cutting machine cheaply, be applicable to the roughing of gear.
