Detailed description of the invention
Referring to figs. 1 through Fig. 6, a kind of squeezing thorax 20 structure of oil press, comprise a squeezing thorax 20 and the squeezing bar 10 in being plugged in the inner chamber squeezing thorax 20, the front end of squeezing thorax 20 is provided with the charging aperture 21 with its inner space, the middle part of squeezing thorax 20 is provided with the oil-out 22 for passing through for grease, the end squeezing thorax 20 is provided with slag notch 23, the front end of squeezing bar 10 is provided with one and can connects to drive the power transmission shaft 11 squeezing bar 10 and rotate by motor-driven, squeeze bar 10 and be provided with the helical blade 12 stock can being pushed to slag notch 23 with the rotation of squeezing bar 10 from charging aperture 21, squeeze bar 10 to reduce gradually from charging aperture 21 to slag notch 23 with the spacing of squeezing thorax 20.Blank is poured in the cavity of squeezing thorax 20 from charging aperture 21 and is promoted by the squeezing bar 10 rotated and extruded fuel-displaced gradually by squeezing bar 10 and squeezing thorax 20, and grease leaches from oil-out 22, discharges after remaining waste residue is pushed into slag notch 23 from slag notch 23.In the present embodiment, slag notch 23 quantity is two, and point to be located at squeeze thorax 20 two side on, can effectively prevent grease from flowing out from slag notch 23, and convenient cleaning.
The end squeezing thorax 20 is provided with a bearing 30, and the end squeezing bar 10 passes this bearing 30 and is connected with a stopping means 40, and this stopping means 40 is resisted against on bearing 30 for limiting squeezing bar 10 relative to squeezing thorax 20 moving from tip forward extreme direction.While squeezing bar 10 promotes blank motion, stock also can apply a reverse thrust to squeezing bar 10, this thrust can promote to squeeze bar 10 makes it move from tip forward extreme direction relative to squeezing thorax 20, and then this thrust is conducted on motor or transmission mechanism, cause the damage of motor or transmission mechanism, the bearing 30 increased and stopping means 40 can carry out spacing to squeezing bar 10, make it cannot move under the effect of this deboost, and this thrust is transferred on bearing 30, energy available protecting motor or transmission mechanism; And this bearing 30 can squeeze with limit, and bar 10 is relative squeezes moving radially of thorax 20; prevent from squeezing bar 10 radial deflection and with squeezing thorax 20 contact internal walls and friction; available protecting squeezes thorax 20 and squeezes bar 10, can reduce motor load simultaneously, improves oil expression efficiency and extends motor service life.
Have employed one in the present embodiment to be screwed onto and to squeeze nut on bar 10 as stopping means 40, and this nut is only resisted against in the inner ring 31 of bearing 30, under the deboost effect of stock, this nut can compress the inner ring 31 of bearing 30, make the inner ring 31 of bearing 30 and squeeze bar 10 synchronous axial system, reduce to squeeze the resistance rotated between bar 10 and squeezing thorax 20, improve oil expression efficiency further, adopt the structure of nut also to facilitate and squeezing bar 10 is mounted and dismounted.Certainly this stopping means 40 also can adopt other the structure such as latch, snap ring.In the present embodiment, stopping means 40 is positioned at the outside of squeezing thorax 20 simultaneously, is easy for installation and removal.
In the present embodiment, the outer shroud 32 of bearing 30 is connected with the interference of squeezing thorax 20 and squeezes on thorax 20 to be fixed on by bearing 30, convenient installation and be also convenient to replacing when bearing 30 damages, and can certainly adopt welding, other modes such as bonding are fixed bearing 30.Also being provided with near the side of squeezing thorax 20 front end the locating convex block 24 be resisted against on outer shroud 32 at bearing 30, for sharing the axial force of squeezing bar 10 pairs of bearings 30 and applying, and being convenient to locate bearing 30 when installing bearing 30.
Because the utility model middle (center) bearing 30 needs to bear larger axial force, therefore preferred selection adopts radial thrust bearing, can certainly adopt the bearing of other types.
Squeeze thorax 20 and also can adopt split type structure, slag notch 23 is together with squeezing the dismountable spiral-lock of main body of thorax 20, and stock can compress slag notch 23 to the deboost squeezing bar 10 makes it can not throw off with the main body of squeezing thorax 20, is convenient to processing and unpicks and washes.
The end squeezing bar 10 can also make multidiameter structure, bearing 30 is resisted against on the cascaded surface of a radial direction near the end face squeezing bar 10 front end, the nut of the other end of bearing 30 will be positioned at, cascaded surface and nut is utilized to step up the inner ring 31 of bearing 30, the inner ring 31 of bearing 30 is made not produce relative sliding with squeezing bar 10, reduce the resistance squeezing bar 10 rotation, improve oil expression efficiency.This multidiameter is also provided with one with bearing 30 on away from the sagittal plane of end face squeezing bar 10 front end, this sagittal plane can carry out spacing to the installation site of stopping means 40, further restriction squeezes bar 10 squeezing the installation site in thorax 20, prevents from squeezing bar 10 and contact internal walls and the friction of squeezing thorax 20.
The foregoing is only preferred embodiments of the present utility model, as long as the technical scheme realizing the utility model object with basic same approach all belongs within protection domain of the present utility model.
