Description
Technical field
This utility model belongs to field of hydraulic equipment, is specifically related to a kind of hydraulic locking sheet on numerical control device.
Background technology
Hydraulic test refers to be transmitted a kind of equipment of pressure by hydraulic oil, because its transmission force is big, it is easy to transmission and
Configuration is extensive in sector application industrial, civilian.In Digit Control Machine Tool in hydraulic test, it would be desirable to the mold members of processing is fixed on
In rotating shaft, then rotating shaft high-speed rotation, carry out the operations such as the processing of mould, milling；After operation terminates, need to be decelerated to stop by rotating shaft
Stop, then mold removal.In prior art, rotating shaft, by driving the traction of motor to realize slowing down, causes moderating process longer, and this
Plant ways of deceleration and can produce bigger stress in rotating shaft, reduce the service life of rotating shaft.
Therefore, this utility model is made that research this side up.
Utility model content
For deficiency of the prior art, this utility model provides a kind of hydraulic locking sheet on numerical control device,
Rotating shaft rotating speed can be reduced fast and efficiently.
This utility model is achieved through the following technical solutions.
Hydraulic locking sheet on numerical control device, including main spindle box and the rotating shaft being located in this main spindle box, described rotating shaft
Keeping belt to be connected by belt pulley thereon with driving motor, described rotating shaft connects brake disc, and described brake disc sets
Having the friction plate for clamping brake disc, described friction plate is driven by oil cylinder piston, and described oil cylinder piston passes through oil circuit and hydraulic pressure
Standing connection, described oil circuit is provided with electromagnetic valve.
Compared to the mode of decelerating through motor of the prior art, in this utility model, by the brake disc being located in rotating shaft
With the rubbing action of friction plate, can the most quickly reduce the rotating speed of rotating shaft, and make it stop operating, when saving technological process
Between.
As preferably, described oil cylinder piston includes housing and the piston being placed in this housing and can moving in the housing, institute
The outer end stating piston is connected with friction plate, and the inner chamber of housing is separated into two parts by the inner of described piston, and divides on housing
It is not provided with the first oilhole and the second oilhole.Hydraulic Station passes through oil circuit oiling in the first oilhole and the second oilhole, drains the oil, Ke Yishi
Existing piston moves back and forth in the housing, promotes friction plate contact with brake disc or separate.
As preferably, described piston is provided with sealing ring with the wall that contacts of housing, it is ensured that close in reciprocating motion of piston
Feng Xing.
As preferably, the both sides of described brake disc are provided with friction plate and the oil cylinder piston of symmetry, are symmetrical arranged guarantee stable
Property.
Compared with prior art, this utility model has the advantages that and improves numerical control device of the prior art
On reducing gear, by the way of hydraulic locking sheet, efficiently, quickly reduce rotating shaft rotating speed, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is a-quadrant enlarged drawing in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings with detailed description of the invention, this utility model is further described.
Seeing Fig. 1 to Fig. 2, the hydraulic locking sheet on numerical control device, including main spindle box 7 be located in this main spindle box 7
Rotating shaft 6, described rotating shaft 6 keeps belt to be connected by belt pulley 61 thereon with driving motor, and described rotating shaft 6 connects brake
Dish 5, the friction plate 4 being symmetrically arranged on two with for clamping brake disc 5 of described brake disc 5, described friction plate 4 is by oil cylinder piston 3
Driving, described oil cylinder piston 3 is connected with Hydraulic Station 1 by oil circuit 11, and described oil circuit 11 is provided with the electromagnetism for oil circuit control
Valve 2.
In present embodiment, described oil cylinder piston 3 includes housing and the work being placed in this housing and can moving in the housing
Plug 33, the outer end of described piston 33 is connected with friction plate 4, and the inner chamber of housing is separated into two parts by the inner of described piston 33,
And on housing, it is respectively equipped with the first oilhole 31 and the second oilhole 32；Described piston 33 is provided with sealing ring with the wall that contacts of housing
34。
During hydraulic locking sheet of the present utility model work, control the hydraulic oil in Hydraulic Station 1 by electromagnetic valve 2 so that it is logical
Cross pipeline 11 to enter in housing, and promote piston 33 to move.When piston 33 is extrapolated, friction plate 4 is released and with brake disc 5
Joint, plays the purpose of brake locking, can the most quickly reduce the rotating speed of rotating shaft 6, and make it stop operating, and saves work
The process flow time.
Protection domain of the present utility model includes but not limited to embodiment of above, and protection domain of the present utility model is with power
Profit claim is as the criterion, and replacement that any those skilled in the art making this technology is readily apparent that, deforms, improves and each fall within
Protection domain of the present utility model.
