Abstract
The utility model relates to a fluid pressure executive mechanism, particularly a hydraulic oscillating motor characterized in a motor structure. The hydraulic oscillating motor is composed of a cylinder body, a shaft, a front end cover, a back end cap, a fixed block and a movable block, wherein, the contact surfaces of the movable block and the fixed block as well as the front end cover and the back end cover form semicircular shapes. The utility model has the advantages of small internal leakage quantity, long service life, high efficiency, stable and reliable motion, large torque, small size, light weight, convenient installation, etc. The utility model is used for metallurgy departments, chemical departments, rubber machinery departments, etc.
Description
The utility model relates to fluid pressure actuator, especially is the hydraulic pressure rotary actuator of feature with the motor configuration.
The hydraulic pressure rotary actuator also is the hydraulic rotating oil cylinder, is used to drive the to-and-fro motion that manufacturing machine is made several angle.Existing product is owing to oil cylinder inner rectangular cavity configuration, so internal leakage is bigger, and working life is shorter.
The purpose of the utility model is to provide a kind of internal leakage less, the novel hydraulic rotary actuator that working life is long.
Above-mentioned purpose adopts oil cylinder inner annular cavity configuration and board-like sealing to realize.
The hydraulic pressure rotary actuator is by cylinder body, with cylinder body with the axle that bearing connects, be contained in the front cover and the rear end cover at cylinder body two ends, be contained in the fixed block on the cylinder body, the movable block that is contained on the axle is formed.The surface of contact of movable block and fixed block and front cover and rear end cover is semicircle.
Below in conjunction with embodiment shown in the drawings, the utility model will be further described.
Accompanying drawing 1 is that the utility model master looks sectional view, and accompanying drawing 2 is the utility model A-A sectional views, and accompanying drawing 3 is the utility model plan views, and accompanying drawing 4 is the utility model left views.Among above-mentioned each figure: 1, axle, 2, joint bolt, 3, O shape circle, 4, movable block, 5, positioning screw hole, 6, bearing, 7, front cover, 8, set screw, 9, fixed block, 10, positioning screwn, 11, cylinder body, 12, rear end cover, 13, pouring orifice, 14, board-like Sealing, 15, pressing plate, 16, movable block mark, 17, keyway.
As shown in Figures 1 and 2, hydraulic swing motor with the axle 1 that cylinder body 11 usefulness bearings 6 connect, is contained in drive end bearing bracket 7 and the rear end cap 12 at cylinder body 11 two ends by cylinder body 11, is contained in the fixed block 9 on the cylinder body 11, and the movable block 4 that is contained on the axle 1 forms. The front end of axle 1 has spline, seals with O type circle 3 between axle 1 and drive end bearing bracket 7 and the rear end cap 12. Drive end bearing bracket 7 and rear end cap 12 usefulness joint bolts 2 are fixed on the cylinder body 11. Hold-down screw 8 is fixed on fixed block 9 on the cylinder body 11. Dog screw 10 is fixed on movable block 4 on the axle 1. Movable block 4 and fixed block 9 are semicircle with the contact-making surface of drive end bearing bracket 7 and rear end cap 12, have formed the annular chamber of hydraulic swing motor inside.
As shown in Figure 2, two pouring orifices 13 are arranged on the cylinder body 11. Movable block 4 and fixed block 9 adopt board-like seal 14 sealings. Board-like seal 14 is fixed on movable block 4 and the fixed block 9 by pressing plate 15 and screw.
As shown in Figure 4, positioning screw hole 5, movable block mark 16 and keyway 17 are arranged on the drive end bearing bracket 7.
The operation principle of hydraulic swing motor is: the side that pressure oil enters cylinder body 11 through a pouring orifice 13 promotes movable block 4 axle 1 is rotated. Spline on the axle 1 is with after manufacturing machine connects, and manufacturing machine is also along with rotation. After turning to certain angle, pressure oil enters the opposite side of cylinder body 11 through another pouring orifice 13, promotes movable block 4 axle 1 is rotated to other direction, and also along with rotating to other direction, namely manufacturing machine is made the reciprocating rotation of certain angle to manufacturing machine.
The hydraulic pressure rotary actuator can adopt vertical or horizontal installation, and the positioning screw hole 5 on the front cover 7, movable block mark 16 and keyway 17 are connection usefulness in location when installing.
The inner ring cavity structure that adopts of hydraulic pressure rotary actuator, movable block 4 adopts board-like Sealing 14 sealings with fixed block 9, motor is in movement process, 11 of front cover 7, rear end cover 12 and cylinder bodies contact with board-like Sealing 14, so the motor internal leakage is less, working life is longer, and the user is as long as the board-like Sealing 14 of periodic replacement just can satisfy production requirement.Because the motor internal leakage is little, thereby have advantages such as efficient height, hydraulic station oil supply volume are little.Motor also has characteristics such as motion is steadily reliable, torsional moment is big, volume is little, in light weight, easy for installation.Can be widely used in departments such as metallurgy, chemical industry, rubber manufacturing machinery.
Embodiment shown in the drawings is a BM-7500 type hydraulic pressure rotary actuator, claims BM-7500 type hydraulic rotating oil cylinder again.Its external dimension are φ 309 * 499.Important technological parameters is: output Maximum Torque 7500Nm, 250 ° of maximum angle of swing, the maximum service pressure 11MPa of oil, 1 ° of required oil mass 15.7cm of revolution
3, weight 150kg.
