Abstract
The utility model discloses a knife collision preventing device for a hydraulic fixture of a numerically-controlled machining center. The knife collision preventing device comprises a hydraulic fixture device, a hydraulic oil way, an equipment controller and a start button, wherein the hydraulic fixture device is used for implementing hydraulic clamping during numerically-controlled machining. The knife collision preventing device is characterized by further comprising a reversing valve; the reversing valve is connected with the oil way; the reversing valve is provided with a pressure sensor which is used for sensing oil pressure; the pressure sensor is connected with the equipment controller through pressure signals; and the equipment controller controls the start button through the pressure signals. With the adoption of the structure, the knife collision preventing device for the hydraulic fixture of the numerically-controlled machining center has the advantages that when the knife collision preventing device is used, the reversing valve is closed, a hydraulic station outputs hydraulic oil, the hydraulic oil passes through the pressure sensor through the reversing valve, the pressure sensor is switched on and sends a signal when normal pressure is sensed by the pressure sensor, the equipment controller receives the signal and is connected with the pressure sensor, the equipment controller unlocks the start button, and then, the start button is effective; and when the reversing valve is not closed, the reversing valve keeps normally open when the pressure sensor senses that the pressure is not normal or no pressure exists, the start button is locked, a machining program does not work, and thus, the occurrence of knife collision accidents is prevented.
Description
Technical field
The utility model relates to the crashproof knife system of numerical control machining center hydraulically operated fixture.
Background technology
In digital control processing; Employed anchor clamps are main with hydraulically operated fixture; And existing numerical control machining center hydraulically operated fixture is carrying out clamping operation back with regard to boot button, and this also starts procedure when just usually causing hydraulically operated fixture not have pressure or insufficient pressure, thereby hits the danger of cutter.
Summary of the invention
The purpose of the utility model is in order to solve above-mentioned prior art problem, the crashproof knife system of the effective numerical control machining center hydraulically operated fixture of program start button when providing a kind of hydraulically operated fixture not have pressure or insufficient pressure.
To achieve these goals; The technical scheme that the utility model adopts is: the crashproof knife system of numerical control machining center hydraulically operated fixture; Comprise the hydraulically operated fixture device, hydraulic circuit, device controller and the start button that carry out the hydraulic pressure clamping when realizing digital control processing; It is characterized in that also comprising reversal valve, said reversal valve and oil circuit join, and reversal valve is provided with the pressure sensor of induction oil pressure; Pressure sensor is connected through pressure signal with device controller, and device controller is controlled start button with pressure signal.
Said hydraulic circuit comprises Hydraulic Station, reversal valve, clamping cylinder, sequence valve and the over draft cylinder that links to each other successively.
Also be provided with overflow valve on the said hydraulic circuit.
The utility model adopts said structure, and in use, reversal valve closes; Hydraulic Station output hydraulic oil passes through pressure sensor through reversal valve; Closed when pressure sensor detects normal pressure, send signal, device controller receives signal and pressure sensor is connected; Device controller solves the locking to start button, and start button is effective; When reversal valve does not close, it is undesired or keep often opening when not having pressure that pressure sensor detects pressure, the start button locking, and procedure does not add row, prevents to hit the generation of cutter accident.
Description of drawings
Fig. 1 is the utility model structure chart;
Fig. 2 is hydraulic circuit figure;
Fig. 3 is for being pressure sensor ball bearing made using figure.
Specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explain:
The crashproof knife system of numerical control machining center hydraulically operated fixture shown in Figure 1 comprises the hydraulically operated fixture device 1 and reversal valve 2 that carry out the hydraulic pressure clamping when realizing digital control processing, and reversal valve 2 is provided with the pressure sensor 3 of induction oil pressure; Hydraulic circuit shown in Figure 2 comprises Hydraulic Station 4, reversal valve 2, clamping cylinder 5, sequence valve 6 and the over draft cylinder 7 that links to each other successively; Said reversal valve 2 joins with oil circuit; Pressure sensor 3 and device controller 8 are connected through pressure signal; Device controller is controlled start button with pressure signal, also is provided with overflow valve 9 on the said hydraulic circuit; As shown in Figure 3, in use, reversal valve closes; Hydraulic Station output hydraulic oil passes through pressure sensor through reversal valve; Closed when pressure sensor detects normal pressure, send signal, device controller receives signal and pressure sensor switch K1 connects; Device controller solves the locking to start button K2, and start button is effective; When reversal valve does not close, it is undesired or keep often opening when not having pressure that pressure sensor detects pressure, the start button locking, and procedure does not add row, prevents to hit the generation of cutter accident.
More than be a specific embodiment of the utility model, yet those of ordinary skill in the art still can make the protection domain that the scheme that does not break away from the utility model still falls into the utility model.
