Description
Technical field
The utility model relates to a kind of milling machine table hydraulic transmission, belongs to hydraulic machinery manufacturing technology field.
Background technique
At present, rough milling of part all uses milling machine to process with half finish-milling.Because product batch is large, milling machine utilization ratio is high, so equipment failure is relatively more frequent, usually affects production.Common fault mostly is on the reciprocating mechanical drive train of worktable, as the wearing and tearing etc. of friction clutch, gear pair, feed screw nut pair.
Model utility content
Object: in order to overcome the deficiencies in the prior art, the utility model provides a kind of milling machine table hydraulic transmission.
Technological scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of milling machine table hydraulic transmission, comprise: fuel tank, worktable, oil hydraulic pump, the first selector valve, the second selector valve, oil hydraulic cylinder, described oil hydraulic pump is connected with fuel tank by pressure oil pipe, the oil hydraulic pump the other end is in series with the import of the first selector valve, the second selector valve respectively by pressure oil pipe, described second selector valve is connected with oil hydraulic cylinder import, and described hydraulic cylinder piston is connected with worktable; Described first selector valve, second selector valve outlet by return tube respectively fuel tank be connected.
Also comprise filter, described filter is arranged in fuel tank, is connected with the pressure oil pipe end of oil hydraulic pump.
Also comprise throttle valve, between described first selector valve, the second selector valve, in pressure oil pipe, be in series with throttle valve.
Also comprise relief valve, described relief valve is connected between oil hydraulic pump and the first selector valve, and relief valve end is connected with fuel tank.
Preferably, described first selector valve is set to hand-operated direction valve.
Preferably, described second selector valve is set to hand-operated direction valve.
Beneficial effect: the milling machine table hydraulic transmission that the utility model provides, output power is large, compact structure, and quality is light; Stable drive, moment of inertia is little.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of milling machine table hydraulic transmission, comprise: fuel tank 1, worktable 2, oil hydraulic pump 3, first selector valve 4, second selector valve 5, oil hydraulic cylinder 6, described oil hydraulic pump 3 is connected with fuel tank 1 by pressure oil pipe, oil hydraulic pump 3 the other end is in series with the import of the first selector valve 4, second selector valve 5 respectively by pressure oil pipe, described second selector valve 5 is connected with oil hydraulic cylinder 6 import, and described oil hydraulic cylinder 6 piston is connected with worktable 2; Described first selector valve 4, second selector valve 5 export by return tube respectively fuel tank 1 be connected.
Also comprise filter 7, described filter 7 is arranged in fuel tank 1, is connected with the pressure oil pipe end of oil hydraulic pump 3.
Also comprise throttle valve 8, between described first selector valve 4, second selector valve 5, in pressure oil pipe, be in series with throttle valve 8.
Also comprise relief valve 9, described relief valve 9 to be connected between oil hydraulic pump 3 and the first selector valve 4, and relief valve 9 end is connected with fuel tank 1.
Specific works process is as follows: during use, fluid is inhaled into oil hydraulic pump by fuel tank through filter, the pressure oil inputted by oil hydraulic pump enters the left chamber of oil hydraulic cylinder by the first selector valve, throttle valve, the second selector valve, promotion piston and worktable move right, and the fluid in the right chamber of oil hydraulic cylinder flows back to fuel tank through the second selector valve.When variation second selector valve handle, pressure oil enters the right chamber of oil hydraulic cylinder, and promotion piston and worktable are moved to the left, and the fluid in the left chamber of oil hydraulic cylinder flows back to fuel tank through the second selector valve 15.The travelling speed of worktable is regulated by throttle valve.The pressure oil that oil hydraulic pump exports is except entering throttle valve, and remaining is opened relief valve and flows back to fuel tank.When variation first selector valve handle, the fluid that oil hydraulic pump exports flows back to fuel tank through the first selector valve, at this moment worktable stop motion.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
