Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of automobile self-locking aiding support cylinder, comprise cylinder body 7, the lower inside of cylinder body 7 installs lower fixed seat 6, the lower inside of lower fixed seat 6 installs piston 12, piston 12 coordinates with the inwall of lower fixed seat 6, piston 12 the other end (piston rod) installs jack-up plug screw 9, tappet spring 1 is installed on the top of jack-up plug screw 9, one end of tappet spring 1 is connected with jack-up plug screw 9, the other end is connected with contact screw 16, contact screw 16 is arranged on the upper end of tappet 8, the inside upper part of cylinder body 7 installs fixed base 2, tappet 8 is installed in the inner side of upper fixed seat 2, piston 12 upper end (piston rod) is arranged on the inner side of tappet 8, jack-up plug screw 9 is positioned at the inner side of tappet 8, several steel ball 10 is installed in tappet 8 periphery, steel ball 10 is between upper fixed seat 2 and lower fixed seat 6, lock sheet 11 is installed inside cylinder body 7, lock sheet 11 is positioned at steel ball 10 side, lock sheet 11 coordinates with steel ball 10, the side week of upper fixed seat 2 installs latching ram 3, latching ram 3 is positioned on the upside of lock sheet 11, the side week of lower fixed seat 6 installs and unclamps piston 4, unclamping piston 4 is positioned on the downside of lock sheet 11, the side of cylinder body 7 is offered and is unclamped hydraulic fluid port 5, unclamp hydraulic fluid port 5 and be positioned at lower fixed seat 6 side.Steel ball 10 of the present invention is centered around tappet 8 conical surface one circle, and it directly holds tappet 8 conical surface tightly; Piston 12 of the present invention, under the effect of oil inlet and oil return pressure (or air pressure), on drive tappet 8, contact screw 16 contacts or departs from workpiece; Lock sheet 11 of the present invention is that the annulus of an inner conical surface is slit into a few lobe, and the angle [alpha] of inner conical surface is less than self-locking friction angle; Latching ram 3 of the present invention promotes lock sheet 11 and moves down under the effect of oil pressure or air pressure, produces self-locking; The piston 4 that unclamps of the present invention, under the effect of oil pressure or air pressure, promotes lock sheet 11 and moves up, and realizes removing self-locking; Tappet spring 1 of the present invention is under the effect of piston 12, and tappet spring 1 promotes contact screw 16 and drives tappet 8 to move, contact workpiece; Tappet 8 of the present invention: contact screw 16, tappet spring 1 and jack-up plug screw 9 are equipped with in tappet 8 upper end, jack-up plug screw 9 is tightened in the top of piston 12 upper end piston rod, when piston rises, jack-up plug screw 9 is driven to rise, jack-up plug screw 9 compresses tappet spring 1, tappet spring 1 promotes contact screw 16 and drives tappet 8 to rise, and contact screw 16 contacts workpiece; When piston 12 declines, tappet 8 is pulled to decline by jack-up plug screw 9; The bottom of tappet 8 is with outside cone angle, and outside cone angle is less than angle of rolling friction.Under oil pressure and gas pressure, first piston (12) rises through compression tappet spring (1) and drives tappet (8) rising, contact screw (16) is made to contact workpiece, then latching ram (3) action, promote lock sheet (11) mobile, promote steel ball (10) and hold tappet (8) male cone (strobilus masculinus) tightly.The compression area of piston (12) is greater than the compression area of latching ram (3); The moving resistance of piston (12) is less than the moving resistance of latching ram (3);
Piston 12 of the present invention rises under the effect of oil pressure or air pressure, compression tappet spring 1, and tappet spring 1 promotes contact screw 16 and drives tappet 8 to rise, and contact screw 16 contacts workpiece; Latching ram 3 moves down under the effect of oil pressure or air pressure, and promote lock sheet 11, lock sheet 11 promotes the conical surface that tappet 8 held tightly by steel ball; Wedging is between steel ball 10 and cylinder body 7 sidewall under the promotion of latching ram 3 for lock sheet 11, and because in lock sheet 11, cone angle is less than mechanical self-latching friction angle, lock sheet 11 can not produce displacement on the sidewall of cylinder body 7, thus reaches the object of mechanical self-latching.Again because the outside cone angle of tappet 8 is less than angle of rolling friction, tappet 8 under the effect of steel ball 10 can not on move.
Locking hydraulic fluid port 15 of the present invention oil-feed, piston 12 rises, and drives jack-up plug screw 9 to rise, compression tappet spring 1, tappet spring 1 acts on contact screw 16, drives tappet 8 to rise, contact screw 16 contacts workpiece, is only the active force of tappet spring 1 to the active force of workpiece;
Latching ram 3 of the present invention promotes lock sheet 11 under the effect of oil pressure, lock sheet 11 promotes the male cone (strobilus masculinus) that tappet 8 locked by steel ball 10, lock sheet 11 is under the effect of latching ram 3 and steel ball 10, wedging is between steel ball 10 and cylinder body 7 inwall, because in lock sheet 11, cone angle is less than mechanical self-latching friction angle, lock sheet 11 can not produce displacement, thus produces mechanical self-latching; Again because the outside cone angle of tappet 8 is less than angle of rolling friction, tappet 8 under the effect of steel ball 10 can not on move, to workpiece produce active force.
Of the present inventionly unclamp hydraulic fluid port 5 oil-feed, unclamp piston 4 and promote lock sheet 11 moves, remove self-locking; Piston 12 drives tappet 8 to move down by jack-up plug screw 9 under the effect of oil pressure.The oil-feed of locking hydraulic fluid port 15, piston 12 rises, and drives jack-up plug screw 9 to rise, compression tappet spring 1, tappet spring 1 acts on contact screw 16, and contact screw 16 and tappet 8 rise, contact screw 16 contacts workpiece, is only the spring force of tappet spring 1 to the active force of workpiece.
Self-locking of the present invention is completely automatic; Function-stable, reliably; Compact structure, fabricating cost is low; The present invention can be used on pneumatic, hydraulic fixture, plays aiding support effect to the part of processing, solves the vibrations of workpiece, improves part processing precision and quality; Manufacturing efficiency is high, function-stable, because self-locking is completely automatic, does not need manual operation; Energy saving: oil of the present invention (gas) cylinder, after self-locking, can be closed hydraulic station or cut off source of the gas.
Second sealing gasket 14, second sealing gasket 14 is installed between described piston 12 and lower fixed seat 6 be arranged on piston block 12.Second sealing gasket 14 of the present invention can improve the sealing between piston block 12 and lower fixed seat 6, avoids because revealing appears between piston block 12 and lower fixed seat 6 in oil pressure or air pressure excessive causing.
Several first sealing gasket 13, first sealing gasket 13 is installed between described lower fixed seat 6 and cylinder body 7 be arranged on lower fixed seat 6.First sealing gasket 13 of the present invention can improve the sealing between lower fixed seat 6 and cylinder body 7, avoids because revealing appears between lower fixed seat 6 and cylinder body 7 in oil pressure or air pressure excessive causing.
3rd sealing gasket the 17, three sealing gasket 17 is installed between fixed seat 2 and cylinder body 7 be arranged on upper fixed seat 2.3rd sealing gasket 17 of the present invention can improve the sealing between upper fixed seat 2 and cylinder body 7, avoids because revealing appears between upper fixed seat 2 and cylinder body 7 in oil pressure or air pressure excessive causing.
