Further, described bearing inner race is closed by the back-up ring handle.
Described protective sleeve adopts a pair of semicircle cover, and elastic insert is established in semicircle cover inboard, installs easy to adjust.
In addition, the utility model also comprises a water fender, and this water fender one end is fixed on the slide block, is positioned at swivel joint one side.When swivel joint just feeds cutting fluid, allow a little off-load and reveal, carry out waterproof by water fender.
The utility model comprises that also one detects the oil cylinder sense switch of loose broaching tool state, and this oil cylinder sense switch is arranged on the blind flange, corresponding piston.
Sealing ring is set respectively between described blind flange and slide block and the piston.
The T type Te Kangge that is provided with between described blind flange and the piston for anti-oil seal encloses, and the O RunddichtringO is set between blind flange and the slide block.
The swivel joint rotating speed reaches as high as 20000r/min.When spindle operation, the broaching tool bar drives the spacer shell rotation, the rotation together of the axle of spacer shell driven rotary joint; Cooling fluid can enter swivel joint by the pipeline that links to each other with swivel joint, and the spacer shell of flowing through enters in the centre bore of broaching tool bar, thereby is sprayed onto on the workpiece by the hollow cutter, and the function of cooling fluid is better brought into play.
Advantage of the present utility model is:
The utility model connects swivel joint and broaching tool bar by spacer shell, adopts the bearing revolution to support spacer shell, and is simple in structure, compact, economical and practical; During main shaft pine broaching tool, the broaching tool bar still can and spacer shell between keep sealing, adaptability is strong; The utility model can move with slide block, can use and with the high-speed main spindle of boring axle, has very strong practical value and good economic benefit.During main shaft pine broaching tool, the broaching tool bar still can and spacer shell between keep sealing.The utility model is simple in structure, compact, has not only effectively guaranteed the cooling of cutting zone, and has realized the lubricated and chip removal of working angles, has improved the service life of cutter and the crudy of workpiece.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the sectional structure schematic diagram of the utility model embodiment.
The specific embodiment
Referring to Fig. 1, Fig. 2, a kind of high-speed main spindle of the present utility model center discharging device is installed on the blind flange 3 on machine tool chief axis piston 1 outer slide 2, cooperates with broaching tool bar 4 in the guide cylinder 17; Described blind flange 3 medial extremitys are sheathed on outside the piston 1, and are connected with slide block 2 by bolt 5, and blind flange 3 central authorities offer the through hole 31 that stretches out for broaching tool bar 4, and through hole, the blind flange outside stretches out and forms a boss 32; Spacer shell 6, one end stretch in the blind flange boss 32, and sheathed being connected in outside the broaching tool bar 4 that stretches out blind flange 3 is equipped with O RunddichtringO 7 between spacer shell 6 and the broaching tool bar 4; Be provided with between spacer shell 6 and the blind flange boss 32 and can turn round the bearing 8 that supports spacer shell, and compress by gland 9; Swivel joint 10 is threaded with described spacer shell 6 outer ends with the left hand thread structure; Swivel joint 10, spacer shell 6 connects with the central through hole of broaching tool bar 4, forms through swivel joint, spacer shell to flow into broaching tool bar centre bore and then be ejected into the path of the cutting fluid on the workpiece; Protective sleeve 11 is sheathed on swivel joint 10 and spacer shell 6 junctions.
Described bearing 8 inner rings are closed by 12 of back-up rings.
Described protective sleeve 11 adopts a pair of semicircle cover, and elastic insert is established in semicircle cover inboard, installs easy to adjust.
In addition, the utility model also comprises a water fender 13, and these water fender 13 1 ends are fixed on the slide block 2, are positioned at swivel joint one side.
The utility model comprises that also one detects the oil cylinder sense switch 14 of loose broaching tool state, and this oil cylinder sense switch 14 is arranged on the blind flange 3, corresponding piston 1.
During the machine cut workpiece, cutter is along with the broaching tool bar rotates with rotation speed n together, and its inner cutting fluid is also along with rotation together, but the pipeline of introducing cutting fluid can't rotate.Therefore, the afterbody connection spacer shell at the broaching tool bar is installed in swivel joint on the spacer shell, and the swivel joint maximum speed can reach 20000r/min, can satisfy the cutting requirement of machine tool chief axis.
When spindle operation, the broaching tool bar drives the spacer shell rotation, the rotation together of the axle of spacer shell driven rotary joint, direction of rotation sees it is counterclockwise from bottom to top, and spacer shell and swivel joint connecting thread are left hand thread, so can not occur connecting loosening phenomenon in the work, guarantee the reliability of device.
The cooling fluid that has a certain pressure by the road, pipe joint, swivel joint, spacer shell flow in the broaching tool bar centre bore, is ejected on the workpiece by hollow handle of a knife or sealing chuck pressure cap and hollow cutter again, and the function of cutting fluid is not fully exerted.
