Specific embodiment
As shown in Figs. 1-2, a kind of machining center running part anticollision mechanism, the running part is screw body, described
Feed screw nut 11 in screw body 1 is equipped with protrusion 12, and 2 center of anticollision mechanism is equipped with screw rod mounting hole 23, the peace
The side wall for filling hole 23 is equipped with static pressure chamber, and the static pressure chamber is mounted in the protrusion 12 of feed screw nut 11, sets in the static pressure chamber
There are fuel feed hole 27, oil outlet 28 and sensor mounting hole 26, the liquid of certain pressure is connected in the static pressure chamber, it is slow to play collision
Effect is rushed, screw body 1 is protected.
In this example, the anticollision mechanism 2 is made of stationary. platen A21 and stationary. platen B22, the stationary. platen A21 and quiet
The center pressing plate B22 is equipped with 23 screw rod mounting holes, and the stationary. platen A21 is equipped with groove A24, and the stationary. platen B22 is equipped with groove
B25, the stationary. platen A21 and stationary. platen B22 are installed together by bolt, and groove A24 and groove B25 is made to form static pressure chamber,
On static pressure chamber two sidewalls, i.e. stationary. platen A21 and stationary. platen B22 are equipped with sensor mounting hole 26 and fuel feed hole 27, static pressure chamber
Bottom be equipped with oil outlet 28, i.e. stationary. platen B23 groove B25 be equipped with oil outlet B；
In this example, the sensor mounting hole 26 and fuel feed hole 27 are symmetrical, and the oil outlet 28 is located at static pressure chamber
Bottom centre.
In this example, liquid is hydraulic oil, the fuel feed hole 27 and oil outlet 28 and isostatic pressing machine phase in the static pressure chamber
Even.
In this example, the static pressure chamber and 11 upper process position of feed screw nut are equipped with sealing ring.
In this example, the aperture of the oil outlet 28 is greater than the aperture of fuel feed hole 27, is convenient for quick pressure releasing, prevents collision from leading
