Abstract

The invention relates to an oil fluid and chip prevention device for a cutter-head spindle of a spiral bevel gear cutting machine, which comprises a cutter shaft. A cutter-head spindle is arranged inside the cutter shaft, a gear-cutting cutter head is arranged on the end of the cutter-head spindle, and a flange matched with the cutter-head spindle is arranged fixedly on the end of the cutter shaft. The invention is characterized in that a circular groove is arranged on the outer end of the inner circumference of the flange matched with the cutter-head spindle mounted fixedly on the end of the cutter shaft; a rotary oil seal is arranged in the circular groove; an oil baffle which is fixed with the flange is arranged at the outer end of the rotating oil seal; an oil protection cover is fixed on the outer circumference of the cutter shaft. With the structure of the invention, when cutting the bevel gear with coolant, not only the chip will be prevented from entering into the cutter shaft body and damaging the spindle, but also the coolant and the chip can be prevented efficiently from splashing all around, this ensures a good machining environment, and lightens the cleaning work. In addition, the invention has the advantages of the simple structure, the reasonable design and the convenient manufacturing.

Description

The oil resistant liquid iron scurf-preventing device of blade disc principal axis of spiral bevel gear processing machine tool
Technical field
The invention belongs to the anti-iron filings device of a kind of anti-fluid, particularly relate to a kind of oil resistant liquid iron scurf-preventing device of blade disc principal axis that is used for spiral bevel gear processing machine tool.
Background technology
Spiral bevel gear processing machine tool be a kind of under the state of cooling a kind of equipment of machining of bevel gears; mill teeth cutterhead wherein can produce a lot of iron filings when the machining bevel gear; iron filings are bonded on mill teeth cutterhead and the processed workpiece through regular meeting; for solving this deficiency; using maximum solutions at present is to take the type of cooling, promptly when the mill teeth cutterhead rotates the smear metal workpiece at a high speed; cooling fluid is poured on mill teeth cutterhead and the processed workpiece, can takes away a large amount of iron filings and heat like this.But, because the high speed of mill teeth cutterhead rotation, iron filings and cooling fluid can be thrown out of, iron filings and cooling fluid are splashed on protective cover, casing and the lathe bed of machining tool workbench, therefore bring very big trouble to cleaning work, especially if untimely cleaning can make iron filings and fluid enter into cutter spindle and cause damage in the main shaft.
Summary of the invention
The present invention provides a kind of oil resistant liquid iron scurf-preventing device of blade disc principal axis that causes damage in the main shaft, can prevent the spiral bevel gear processing machine tool of the protection main shaft that fluid and anti-iron filings splash that is used for not making for solving the deficiency that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of oil resistant liquid iron scurf-preventing device of blade disc principal axis of spiral bevel gear processing machine tool, the inside that comprises cutter shaft body, cutter shaft body is equipped with the mill teeth cutterhead is housed on cutter spindle, the cutter spindle end face, is fixed with the ring flange that cooperates with cutter spindle on the end face of cutter shaft body, be characterized in, the place, inner periphery outer face that is fixed with the ring flange that cooperates with cutter spindle on the end face of cutter shaft body has cannelure, rotary oil seal is housed in cannelure, the oil baffle that installs with ring flange is housed in the outer end of rotary oil seal; On the excircle of cutter shaft body, be fixed with oil blocking cover.
The present invention can also adopt following technical measures:
On the end face of cutter shaft body, be fixed with ring flange that cutter spindle cooperates in the rotary oil seal cross section that is equipped be n shape, its inside is provided with L shaped fixed mount, have rectangular channel at rotary oil seal near the ring flange place, being shaped on two triangular hills, dead ring is installed at the back side of rotary oil seal triangular hill near the main shaft side.
The lower side of the oil blocking cover that installs on the excircle of described cutter shaft body has rectangular aperture.
Advantage and good effect that the present invention has are: owing to be fixed with the ring flange that cooperates with cutter spindle on the end face of cutter shaft body, place, inner periphery outer face at its ring flange has circular trough, rotary oil seal is housed in cannelure, is equipped with ring flange in the outer end of rotary oil seal and is fixed with oil baffle; On the excircle of cutter shaft body, be fixed with oil blocking cover; Therefore structure of the present invention can prevent that iron filings from entering the cutter shaft body and not damaging main shaft during machining of bevel gears under the state of cooling, can prevent effectively that again cooling fluid and iron filings from splashing everywhere, has guaranteed good processing environment, has alleviated a large amount of cleaning works.The present invention also has advantages such as simple in structure, reasonable in design, easily manufactured in addition.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is an I portion enlarged drawing among Fig. 1;
Fig. 3 is a user mode reference diagram of the present invention.
Among the figure: 1, oil blocking cover; 2, oil baffle; 3, ring flange; 4, rotary oil seal; 4-1, fixed mount: 4-2, rectangular channel; 4-3, dead ring; 4-4, triangular hill; 5, cutter spindle; 6, mill teeth cutterhead; 7, cutter shaft body, 8, screw; 9, screw; 10, screw; 11, bearing; 12, rectangular aperture; 13, spiral bevel gear processing machine tool.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 3, in the cutter shaft body 7 of spiral bevel gear processing machine tool 13, cutter spindle 5 is installed, end face at cutter spindle 5 is equipped with mill teeth cutterhead 6, between cutter spindle and cutter shaft body, bearing 11 is housed, on the end face of cutter shaft body 7, be fixed with ring flange 3 by screw 9, the place has cannelure in ring flange inner periphery outer face, the rotary oil seal 4 that seals is housed in cannelure, for making rotary oil seal play better sealing function, the rotary oil seal cross section made be n shape, also be provided with L shaped fixed mount 4-1 in rotary oil seal, present embodiment is elected the fixed mount material as steel material.And also be shaped on two triangular hill 4-4 at rotary oil seal near the main shaft side, see also Fig. 2, can make rotary oil seal play the effect of dual-seal protection like this.In addition, have rectangular channel 4-2 near the ring flange place, at the back side of triangular hill 4-4 dead ring 4-3 is housed, rotary oil seal 4 is fastened on the cutter spindle 5 by dead ring 4-3 by rectangular channel at rotary oil seal.In the outer end of rotary oil seal oil baffle 2 is housed, oil baffle installs by screw 10 and ring flange 3.On the excircle of cutter shaft body, be fixed with oil blocking cover 1 by screw 8, it can play the effect that prevents that fluid and iron filings from splashing, having rectangular aperture 12 at the oil blocking cover downside in addition, is to flow out from rectangular aperture 12 when mill teeth cutterhead 6 rotates at a high speed for convenience of fluid and iron filings.
