Specific implementation mode
The following describes the present invention in detail with reference to the accompanying drawings and embodiments.
Refering to fig. 1, Fig. 2 and Fig. 3, one embodiment of the hydraulic brake system 100 of turnning and milling head 200 of the present invention, the turnning and milling
First 200, which also include an axle bed unit 210, one extended along an axis L, can rotate and be installed in the axle bed unit 210
220, main axle units 230 for being connected to the B axle unit 220 of B axle unit in portion and one are installed on the axle bed unit
210 and the B axle unit 220 can be driven and drive the main axle unit 230 using axis L as center of rotation generate rotation driving list
Member 240.There are one cam 241 and a roller wheel 242 by 241 stopper of cam, the rollers for the driving unit 240 tool
Wheel 242 is connected to the B axle unit 220.
The hydraulic brake system 100 includes 10, cylinder chambers 20 of a friction member and a brake component 30.
The friction member 10 is set to 210 inside of axle bed unit and is connected to the B axle unit 220, which surrounds
Axis L is in hollow and annular, and there are one around axis L and substantially perpendicular to the rubbing surface 11 of axis L for tool.
The cylinder chamber 20 is set to inside the axle bed unit 210, and is set to 10 side of friction member, this reality along axis L
It applies in example, which is in hollow ring channel-shaped around axis L, and the cross sectional shape which is parallel to axis L is H-shaped,
And has and be parallel to axis L there are one the radial space 21, one substantially perpendicular to axis L and be communicated in the radial space
Pressure oil can be imported the first deflector hole 23 of 21 side of radial space by 22 axial space 22, one and an edge should
Axis L is set to 23 side of the first deflector hole and pressure oil can be imported to the second deflector hole of 21 other side of radial space
24.It is noted that the medium that can import first deflector hole 23 and second deflector hole 24 is not limited with pressure oil, also can
For water or gas, only these gaseous states, liquid medium compressibility come well unlike pressure oil, so in the present embodiment, directly
Announcement is connect using pressure oil as hydraulic medium.
The brake component 30 tool there are one can be moved along axis L and be installed on the cylinder chamber 20 main body 31 and a company
It is connected to the main body 31 and the braking parts 32 of the cylinder chamber 20 can be piercing in, the cross sectional shape which is parallel to axis L is in H
Shape, and there are one parallel substantially perpendicular to axis L and the radial wall 311 being located in the radial space 21 and one for tool
In axis L and the substantially perpendicular axial ring wall 312 for being connected to the radial wall 311, the radial wall 311 is between first water conservancy diversion
Between hole 23 and second deflector hole 24, which is located in the axial space 22.The braking parts 32 are set to the axis
To the end of ring wall 312.
Again as shown in Figures 1 and 3, show that the radial wall 311 of the brake component 30 is under pressure oil (such as Fig. 3 dotted arrows institute
Show) effect of the radial space 21 is incorporated in from first deflector hole 23, the brake component 30 is whole to move (such as Fig. 3 along axis L
Shown in solid arrow), which is detached from a first position in the rubbing surface 11, at this point, starting the driving unit
240 can the link B axle unit 220 and main axle units 230 using axis L are center of rotation relative to the axle bed unit 210 production
Raw rotation, can adjust the machine direction for a cutter (not shown) for being installed on the main axle unit 230.
When the cutter has turned to predetermined direction, start pressure oil (as shown in Fig. 4 dotted arrows) from second water conservancy diversion
Hole 24 is incorporated in the effect of the radial space 21, and the brake component 30 is whole to be moved along axis L (as shown in Fig. 4 solid arrows),
The braking parts 32 generate braking a second position, and towards the rubbing surface 11, at this point, can make the cutter of the main axle unit 230
The machine direction of (not shown) generates positioning.
Therefore, the brake component 30 is driven to generate the effect braked relative to the friction member 10 along axis L using pressure oil,
Snubber elastomeric is generated when the braking parts 32 can be enable to generate braking to the rubbing surface 11, the brake component 30 and the friction can be made
Part 10 generates rebound effect when generating friction, can reduce between brake component 30 and friction member 10 because of vibrations caused by braking,
And avoid damage between opposed member.
In addition, the hydraulic brake system 100 of turnning and milling head 200 of the present invention when carrying out braking maneuver, can utilize servo oil
The mode of pressure has the function that pressure adjustable is whole, and can generate different frictional dampings, once the driving unit 240 has back clearance
When generation, the influence of back clearance can be allowed to be preferably minimized using the frictional damping, and preferable machining accuracy can be maintained, it need not be through
Normal adjustment back clearance, and production capacity can be promoted and reduce manufacturing cost.
In conclusion the hydraulic brake system of turnning and milling head of the present invention, it is easy that overall structure is simple, manufacture assembles, and can reach
The influence that back clearance is reduced to braking buffering and using frictional damping, can reach the purpose of the present invention really.
