Description
Technical field
The utility model belongs to machine tool field more particularly to machine tool chief axis.
Background technique
Use of the main axle unit central water outlet on lathe is all the more extensive, especially in machining center, high in numerically controlled lathe etc.
End numerically controlled lathe largely uses, and can effectively act as cooling down and rushing bits effect.With numerically controlled lathe to high speed, efficiently, it is high
Precision, automation, intelligent direction development, clear up workpiece positioning surface ability on fixture to machine spindle speed and lathe automatically
Requirement it is higher and higher, especially digital control lathe clamper positioning surface rushes bits quality, directly affects working efficiency and workpiece dress
The precision of folder.Spindle of numerical control lathe central water outlet structure at present considers punching to be worth doing medium and outlet pipe using gyrator or swivel joint
It connects.Outlet pipe and the design of chuck pull rod are integrated by the structure, and causing faucet with main shaft, chuck clamps is synchronous rotation
Turn, on fixture positioning surface and claw be relatively stationary, efficiently the iron filings on claw and positioning surface cannot be rinsed dry
Only.Meanwhile the structure of swivel joint limits that its rotational speed is lower, to limit the maximum speed of Spindle Unit of Machine Tool.
And the cleannes of gyrator or swivel joint fluid medium are more demanding, need to increase filtering at swivel joint supply pump
Device, it is not only at high cost, and easy break-down.Cause lathe revolving speed it is low, it is at high cost, punching consider to be worth doing ineffective, workpieces processing precision
The problems such as overproof, poor reliability.
Utility model content
In order to solve deficiency in the prior art, providing one kind can adapt to revolution at a high speed main shaft, and not with main axis,
The operation is stable and numerically controlled lathe High-sp eed spindle unit central water outlet scrap flushing device with long service life, used by the utility model
Technical solution is:
A kind of numerically controlled lathe High-sp eed spindle unit center scrap flushing device, includes angling cylinder, main shaft, pull rod and card
Disk, the angling cylinder piston rod be it is hollow, the pull rod, which is located in main shaft, to be rotated and can axially stretch along main shaft with main shaft
Contracting, the pull rod be it is hollow, the main shaft is connect with external power supply, it is characterised in that: further include having jet water spout, it is described
Jet water spout include water inlet end and water spray end, the jet water spout passes through oil cylinder and pull rod and water spray end extend out to chuck jaws position
It sets, bearing is equipped between the jet water spout and pull rod, the jet water spout water inlet end is connect with lathe hose.
The bearing is deep groove ball bearing.
The jet water spout includes positioned at the water pipe head of water inlet end and positioned at the nozzle at water spray end and by water pipe head
The water service pipe being connected to nozzle.
It is equipped on the nozzle towards chuck jaws hole for water spraying.
The hole for water spraying towards chuck positioning surface is additionally provided on the nozzle.
The utility model has the beneficial effects that the device does not need to efficiently avoid using swivel joint because of swivel joint
Bring revolving speed is not high, cooling medium cleannes are required with harsh and poor reliability, problem at high cost, while outlet pipe sprays
Mouth can be formed with chuck clamps positioning surface, claw and be relatively rotated, and axial linear movement can also be done with pull rod, and dynamic rinses claw
And positioning surface.And the nozzle of outlet pipe can be customized according to the claw of different shape and size, positioning surface, and it can be by cooling
Medium is accurately transmitted to required position.Water service pipe spring bearing is deep groove ball bearing, and revolving speed is much higher than machine spindle speed.
The device can also be used to rush bits in hollow part hole.The characteristics of device is that at low cost, good reliability, punching bits effect be good, revolving speed
Height is easily installed and replaces, and has been used for production and marketization application.

Specific embodiment
Numerically controlled lathe revolution at a high speed main shaft as depicted in figs. 1 and 2 include: angling cylinder 1, main shaft 5, pull rod 6, chuck 2 with
And jet water spout 3,1 telescopic rod of angling cylinder and pull rod 6 are hollow structure so that jet water spout 3 can extend there through, thus to card
Disk 2 is implemented to rinse cutting and the impurity at cleaning chuck position, and wherein chuck 2 is connect by pull rod 6 with angling cylinder 1, by returning
Turning oil cylinder 1 drives pull rod 6 to drive 7 clamping of claw or release on chuck 2.Pull rod 6 be located in main shaft 5 rotated together with main shaft and
It can be realized expanding-contracting action, chuck 2 is connected with main shaft 5 and rotates together, and main shaft 5 connect realization rotation, angling cylinder 1 with power source
Cylinder body is then fixed on lathe not with main axis.Jet water spout 3 includes water inlet end and water spray end, and water inlet end is placed in angling cylinder one
Side, the jaw position that water spray end extend out to chuck 2 realize the flushing to 2 upper clipping claw 7 and positioning surface of chuck.Jet water spout 3 and pull rod 6
Between setting bearing 10 support, be able to bear high speed rotation when main shaft 5 works in order to ensure bearing 10, which preferably selects depth
Ditch ball bearing, and in order to make jet water spout 3 remain stationary state, 3 water inlet end of jet water spout is fixed on lathe, in the present embodiment
It is equipped on lathe and is mounted on anti-rotation bracket 4 for fixing the water inlet end of jet water spout 3, so that jet water spout 3 when main axis
Remain stationary state.
Jet water spout 3 as shown in Figure 3 includes the water pipe head 8 positioned at water inlet end and the nozzle 11 positioned at water spray end and by water
