Description
Technical field
The present invention relates to the lathe cutter saddle new structure, be particularly useful for the lathe cutter saddle of gear-hobbing machine and gear grinding machine with worm grinding wheel.
Background technology
Gear is a kind of key foundation property member, is widely used in all kinds of machineries.Gear-hobbing machine then is to use maximum main gear cutting machines in the Gear Processing, and its intermediate slide is again one of gear-hobbing machine two big vitals.Along with science and technology development, gear cutting machine has been proposed increasingly high requirement, be mainly reflected in aspects such as numerical control, efficient, high accuracy and environmental protection processing.
The knife rest of tradition gear-hobbing machine; Its bracket is installed on the rail plate of main shaft slide plate chair; The main shaft slide plate chair is installed on the rail plate of tool holder casing, and therefore, the secondary cutter frame structure of this two-stage rail plate causes the distance between cutter mandrel and the tool holder casing location and installation face bigger than normal; The disturbing moment that cutting force is caused is excessive, and the gear hobbing precision is on the low side; Secondly, also cause the complex structure of knife rest, the combination low precision.Simultaneously, the cutter mechanism of scurrying of traditional gear-hobbing machine is arranged between tool holder casing and the main shaft slide plate chair, makes and the assembly technology complicacy; The main shaft slide plate chair is a concave curvatures, has problems such as chip removal difficulty.
In sum, the knife rest of traditional gear-hobbing machine exists complex structure, the combination precision is low, manufacturability is poor, chip removal is difficult, bear defectives such as disturbing moment is big, machining accuracy is on the low side in the working angles.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, good rigidly, the combine and assemble precision is high, assembly technology is simple, can effectively improve the lathe cutter saddle of machining accuracy.
For this reason; The present invention adopts following technical scheme: a kind of lathe cutter saddle; Include tool holder casing, bracket, main shaft, main shaft slide plate chair, spindle drive systems, scurry the cutter motor and be installed in bracket and main shaft between the cutter mandrel, its key is: only a tool holder casing is provided with rail plate, and bracket and main shaft slide plate chair lower end are slab construction; Bracket and main shaft slide plate chair pass through slider support respectively on rail plate, and the bracket retaining mechanism is installed between bracket and the main shaft slide plate chair.
The present invention only is provided with rail plate on tool holder casing; Adopt the plate structure of the rail plate on bracket and the shared tool holder casing of main shaft slide plate chair; So just can reduce the distance between cutter mandrel and the tool holder casing location and installation face, effectively reduce the disturbing moment that produces in the cut.Compare with the cutter frame structure that traditional two-stage rail plate is secondary, structure is simpler, compact, good rigidly, and assembly technology is able to simplify, and is convenient for installation and maintenance, guaranteed the assembly technology precision, thereby improves part processing precision.
Further; Cutter mandrel one end cooperates with the hole of bracket, and the other end is clamped in the combined type chuck of tight nut with lock, and lock nut has the diminished shaft neck; This collar cooperates with the bellmouth of spindle end; The shade portion of lock nut and the external screw thread of spindle end are connected, and on the main shaft slide plate chair, spindle end links to each other with spindle drive systems main shaft through bearings.Utilize the locking of taper surface between lock nut collar and the main shaft to be used for tool setting tool mandrel one end and fix, loading and unloading are simple, convenient, can also improve the axiality between cutter mandrel and the main shaft.
Further, scurry the cutter motor and be installed on the tool holder casing, be connected through feed screw nut pair between the output shaft of scurrying the cutter motor and the main shaft slide plate chair, screw pair places the left side or the right side of main shaft slide plate chair.So just can link to each other with the left side or the right side of main shaft slide plate chair, effectively improve the lengthy and tedious and space availability ratio of conventional knives shelf structure, reduce processing and manufacturing and assembly cost scurrying the cutter motor.
Adopt technical scheme of the present invention, the cutter frame structure that is used in gear-hobbing machine or gear grinding machine with worm grinding wheel is simple, good rigidly, and assembly process process is good, and assembly precision is high, can effectively improve the machining accuracy of part, and cut is suitable for doing, wets.

Fig. 3 is the left view of Fig. 1.
Among the figure: 1. tool holder casing; 2. rail plate; 3. slide block; 4. bracket retaining mechanism; 5. bracket; 6. cutter mandrel; 7. lock nut; 8. main shaft; 9. main shaft slide plate chair; 10. nut; 11. screw mandrel; 12. spindle drive systems; 13. scurry the cutter motor.
The specific embodiment
Through specific embodiment the present invention is elaborated below.
Extremely shown in Figure 3 like Fig. 1; A kind of lathe cutter saddle; Be used for gear-hobbing machine or gear grinding machine with worm grinding wheel; Have tool holder casing 1, bracket 5, main shaft 8, main shaft slide plate chair 9, spindle drive systems 12, scurry cutter motor 13 and be installed in bracket 5 and main shaft 8 between cutter mandrel 6, tool holder casing 1 is provided with rail plate 2, bracket 5 is slab construction with main shaft slide plate chair 9 lower ends; Bracket 5 is supported on the rail plate 2 through slide block 3 respectively with main shaft slide plate chair 9, and bracket retaining mechanism 4 is installed between bracket 5 and the main shaft slide plate chair 9.That is to say; Bracket 5 is supported on the same rail plate pair on the tool holder casing 1 with main shaft slide plate chair 9; Concrete, about bracket 5 passes through each slider support on rail plate 2, about main shaft slide plate chair 9 passes through totally four slider support on rail plate 2.Bracket retaining mechanism 4 is used for when loading and unloading cutter mandrel 6, locking or unclamping bracket 5.
Rail plate on bracket 5 and the main shaft slide plate chair 9 shared tool holder casings 1; So just can reduce the distance between cutter mandrel 6 and the tool holder casing 1 location and installation face, thus the disturbing moment that reduces to produce in the cut, and also structure is simpler, compact, good rigidly; Simplified the assembly technology of knife rest each several part; Convenient for installation and maintenance, guarantee the assembly technology precision, thereby can significantly improve part processing precision.Main shaft slide plate chair 9 adopts slab constructions, has overcome that the main shaft slide plate is the problem that there is the chip removal difficulty in concave curvatures in the traditional design, is suitable for doing, wet cutting.
