Abstract
The utility model relates to a hydraulic system, in particular to a hydraulic system of a beam locking cylinder of a vertical lathe, and belongs to the technical field of vertical lathes. The hydraulic system comprises an oil tank filled with hydraulic oil, an oil sucking pipe is arranged in the oil tank, a motor pump is connected to the upper end of the oil sucking pipe, the motor pump is connected with a high pressure oil filter through a first hydraulic pipe, the high pressure oil filter is connected with a check valve through a second hydraulic pipe, the check valve is connected with an electromagnetic directional valve through a third hydraulic pipe, and the electromagnetic directional valve is connected with the locking cylinder through a fourth hydraulic pipe. An overflow valve is connected to the second hydraulic pipe and connected with the oil tank through an oil return pipe. The hydraulic system is simple, compact and reasonable in structure, enough beam locking force is provided, the danger that the beam falls down because of self gravity is avoided, and working safety is improved.
Description
Technical field
The utility model relates to a kind of hydraulic system, and a kind of cross beam lock locking oil cylinder hydraulic system that is applicable to vertical car specifically, belongs to vertical car technical field.
Background technology
In vertical lathe, crossbeam often can be because original weight be come, and with former crossbeam retaining mechanism, it is inadequate that intensity just seems.In view of the problem of above-mentioned existence, in the urgent need to developing a kind of cross beam lock locking oil cylinder hydraulic system structure of novel vertical car.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of simple in structure, ingenious, rational cross beam lock locking oil cylinder hydraulic system of vertical car is provided, and enough crossbeam coupling mechanism forces are provided, the danger of avoiding crossbeam and dropping because of deadweight.
The technical scheme providing according to the utility model, a kind of cross beam lock locking oil cylinder hydraulic system of vertical car comprises the fuel tank of filling hydraulic oil, it is characterized in that: in fuel tank, be provided with fuel sucking pipe, fuel sucking pipe upper end connects electric-motor pump, electric-motor pump connects high-pressure filter by the first hydraulic tube, high-pressure filter connects check valve by the second hydraulic tube, and check valve connects solenoid directional control valve by the 3rd hydraulic tube, and solenoid directional control valve connects locking cylinder by the 4th hydraulic tube.On the second hydraulic tube, connect overflow valve, overflow valve connects fuel tank by oil return pipe.
Further, in fuel sucking pipe, be provided with oil absorption filter screen.
Further, Bonding pressure switch on the 3rd hydraulic tube, Bonding pressure table in pressure switch.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, and enough crossbeam coupling mechanism forces are provided, and the danger of avoiding crossbeam to drop because of deadweight has improved the security of working.
Accompanying drawing explanation
Fig. 1 is the utility model hydraulic system structure figure.
Description of reference numerals: 1-locking cylinder, 2-solenoid directional control valve, 3-check valve, 4-overflow valve, 5-fuel tank, 6-Pressure gauge, 7-pressure switch, 8-high-pressure filter, 9-electric-motor pump, 10-oil absorption filter screen, 11-fuel sucking pipe, 12-oil return pipe, 13-the first hydraulic tube, 14-the second hydraulic tube, 15-the 3rd hydraulic tube, 16-the 4th hydraulic tube.
The specific embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1, the utility model mainly comprises the fuel tank 5 of filling hydraulic oil, is provided with fuel sucking pipe 11 in fuel tank 5, is provided with oil absorption filter screen 10 in fuel sucking pipe 11, and oil absorption filter screen 10 is for filtering the impurity of hydraulic oil in fuel tank.
High-pressure filter 8 connects check valve 3 by the second hydraulic tube 14, and check valve 3 connects solenoid directional control valve 2 by the 3rd hydraulic tube 15, and solenoid directional control valve 2 connects locking cylinder 1 by the 4th hydraulic tube 16.
The equalizing pressure of overflow valve 4 is set as 10Mpa, the pressure of oil circuit in Pressure gauge 6 indication mechanisms.
The utility model arranges locking cylinder 1 on crossbeam, when needs are locked crossbeam, system oil-feed, solenoid directional control valve 2 is switched on, the right position work of solenoid directional control valve 2, fluid is opened check valve 3 via electric-motor pump 9, and fluid enters the left chamber of locking cylinder 1 via the right bit stream of solenoid directional control valve 2, and the piston rod of locking cylinder 1 moves right.
During system oil return, solenoid directional control valve 2 power-off, the left position connecting system oil circuit of solenoid directional control valve 2, now locking cylinder 1 makes piston rod to left movement because of the reset force of spring, and the fluid in locking cylinder 1 enters fuel tank 5 via the left bit stream of solenoid directional control valve 2.The fluid now flowing out from electric-motor pump 9 will be more poly-more in system, and when pressure reaches after the operating pressure of overflow valve 4, overflow valve 4 is opened automatically, and fluid flows back to fuel tank 5 through oil return pipe 12.
The utility model is simple in structure, compact, reasonable, and enough crossbeam coupling mechanism forces are provided, and the danger of avoiding crossbeam to drop because of deadweight has improved the security of working.
