Abstract
The main transmission system of a large turbine disk mortise broaching machine. Motive power passes a coupler 1 to be input through a main transmission shaft 2. A left cylindrical helical gear 4 and a right cylindrical helical gear 5 are positioned axially through a sleeve 3, a shaft sleeve 6 and an end cover 7. Due to the fact that the gear is meshed with a rack, rotary motion is converted into linear motion. The left cylindrical helical gear 4 and the right cylindrical helical gear 5 are respectively meshed with a left helical gear 8 and a right helical gear 9. The left helical gear 8 and the right helical gear 9 are positioned on a main sliding plate 12 accurately through pressing blocks 10 and fixed on the main sliding plate 12 through an end face key 15 and an end face key 16 so as to transmit load. The gap between the gear and the rack is adjusted through an inclined plane between the end face key 15 and the end face key 16. The main sliding plate 12 is installed on a linear guide rail 11 to perform reciprocal rectilinear motion. A knife rest 14 is installed on the main sliding plate 12. A knife box 13 is installed on the knife rest 14. The main transmission system of the large turbine disk mortise broaching machine is simple in structure and easy to install, scale side clearance can be adjusted through the end face keys and a pressing plate so as to reduce error, the two helical gears are installed reversely to offset axial force so as to transmit large distortion.
Description
Technical field
The invention belongs to this field of large-scale turbine disk tongue-and-groove machining tool in the broaching lathe.
Background technology
Aero-engine is the complicated thermal machine of under the high speed conditions of HTHP, working reliably and with long-term; It is that resistance when overcoming aircraft flight provides motive force; And the turbine disk is one of the most key part of engine; Its for a long time at a high speed, the environment work down of high temperature, therefore generally on material select to have high strength, can resistant to elevated temperatures material, structural design is complicacy also.Between the aircraft engine turbine disk and blade, promptly couple together with tongue-and-groove.In the processing of the turbine disk, the difficulty of processing of tongue-and-groove is maximum, also is the place of key problem in technology.
Main transmission is one of main task of turbine disk tongue-and-groove broaching machine research; Chinese scholars has been done a lot of researchs to it in recent years; But engine works' processing tongue-and-groove mostly is on the horizontal hydraulic transmission broaching machine of the fifties production, to carry out at home at present, lathe poor rigidity, broaching tool guiding weak point.The low requirement that can't satisfy increasingly high precision of tongue-and-groove and surface roughness of broaching speed.Broaching main motion power demand is big, cutting force is big, adopts the general kind of drive, and the complex structure cost is high.
General Machine Tool Main Drive adopts ball screw assembly, mostly, be difficult to satisfy the characteristics of the big impulse stroke of broaching machine main transmission, and cost is higher.The restriction of main transmission power, broaching speed, stroke has seriously restricted surface smoothness, the surface quality of the final finished surface of tongue-and-groove.Affect cutter life and production efficiency.A kind of main transmission that is suitable for large-scale turbine disk tongue-and-groove machining tool is badly in need of developing.
The large-scale turbine disk tongue-and-groove broaching main transmission system of machine tool of this patent design; With broaching tool and tool rest horizontal positioned; Belong to lateral recumbent posture broaching lathe, make broaching tool and tool rest do horizontal linear reciprocating motion at the following needs of the support of horizontal guide rail, main motor is arranged in the rigidity that side has strengthened lathe.Make the control of main transmission become simply, be easy to reach desired machining accuracy.
Summary of the invention
The technical problem that this patent solves is: to existing broaching Machine Tool Main Drive underpower; Can only the low speed broaching etc. defective; Invented a kind of high speed broaching main transmission; Frequency control through servomotor can realize that low speed arrives broaching campaign at a high speed, and big cutting force can be provided, and makes broaching tool and tool rest under the driving of rack-and-pinion, make linear reciprocating motion broaching workpiece through servomotor.
The large-scale turbine disk tongue-and-groove broaching machine main transmission of this patent invention is characterized in that: power is imported through final drive shaft 2 through shaft coupling 1. Sleeve 3 and 7 pairs of axle sleeve 6, end caps, left cylindric spiral gear 4 carries out axial location with right cylindric spiral gear 5.Through the rack-and-pinion engagement, will rotatablely move is converted into rectilinear motion.A left side cylindric spiral gear 4, right cylindric spiral gear 5 respectively with left helical rack 8,9 engagements of right helical rack.Left side helical rack 8 is accurately located on main cargo chute 12 through briquetting 10 with right helical rack 9, is fixed on transmitted load on the main cargo chute 12 through straight end-face key 15 and straight end-face key 16 then.Pass through the gap of inclined-plane adjustment rack-and-pinion between straight end-face key 16 and the straight end-face key 17.Main cargo chute 12 is installed in and carries out linear reciprocating motion on the line slideway 11, and tool rest 14 is installed on the main cargo chute 14, and cutter box 13 is installed on the tool rest 14.
Said line slideway 11 is fixed on the bed piece 17.
Said power is provided by servomotor 18, and servomotor 18 is installed on the lathe bed 17.
Said final drive shaft 2 links to each other with decelerator 20 through shaft coupling 21, and decelerator 20 equally is installed on the bed piece 17 with servomotor, links to each other through shaft coupling 19 between the two.
Said left helical rack 8 and right helical rack 9, through wedge 22 wedgings on main cargo chute 12.
