The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
Among Fig. 1; Motor 3 makes hydraulic pump 4 that hydraulic oil is pumped in the hydraulic cylinder body 6, promotes the certain scale of small piston rod 33 to the right with hand, and the hydraulic path in the big piston makes hydraulic cylinder 6 left chambeies be communicated with right chamber; Be that hydraulic cylinder 6 left chambeies equate with the oil pressure in right chamber; Because the area on big piston 7 left sides can know that by F=P*A big piston 7 and big piston bar 9 can move right identical scale, till first hydraulic path 8 in making big piston 7 is sealed again greater than the area on the right; Spur the certain scale of small piston rod 33 left with hand; Second hydraulic path 29 in the big piston 7 makes hydraulic cylinder 6 left chambeies be communicated with oil-out 24; Be that hydraulic cylinder 6 left chamber oil pressure are zero; Because hydraulic cylinder 6 right chamber oil pressure are greater than left chamber oil pressure, big piston 7 and big piston bar 9 can be to the identical scales of left movement, till second hydraulic path 29 in making big piston is sealed again; When valve piston 27 was in first hydraulic path 8 and second hydraulic path, 29 closed conditions, even the position of motor 3 work also can't change big piston bar 9, hydraulic oil flowed back to fuel tank through overflow valve 5, promptly has latch functions.Utilization acts on power control action less on the small piston rod 33 bigger power on big piston bar 9, makes the vacuum cup 17 at big piston bar 9 tops accomplish with the adhesive of automobile depression steel plate face, extract work.
Among Fig. 2, there is a hole 27 at big piston 7 centers and has first hydraulic path 8 and second hydraulic path 29; Big piston bar 9 middle parts have hole 22 and communicate with oil-out 24 through annular groove 23; Big piston bar 9 tops are threaded with vacuum cup 17 usefulness, can select for use the vacuum cup of corresponding size to be connected with big piston bar 9 according to the size of autobody sheet notch area; 22 two ends, big piston bar hole are with gasket seal 11 and 20 sealings; First hydraulic path 8 makes hydraulic cylinder body 6 left chambeies be communicated with right chamber; Second hydraulic path 29 makes hydraulic cylinder body 6 left chambeies be communicated with oil-out 24 through big piston bar internal hydraulic pressure path 26; Small piston rod 33 tops indicate graduation mark 37, accurately to control automobile depression position leveling precision; End cap 31 is used to limit the maximum displacement that valve piston 28 is moved to the left; Screw thread support bar 14 tops cooperate with rubber cushion blocks 16 and process screw thread support bar adjusting nut 15 and can freely adjust height according to the cave in shape of steel plate face of automobile; Rubber cushion blocks 16 has certain area and thickness autobody sheet face when preventing to keep in repair and occurs depression once again.
In the workflow of the automobile depression apparatus for leveling of Hydrauservo System control shown in Figure 3; Motor 3 makes hydraulic pump 4 that hydraulic oil is pumped into hydraulic cylinder body 6; If small piston rod 33 does not move; When then first hydraulic path 8 and second hydraulic path 29 were in closed condition all the time, hydraulic oil flowed back to fuel tank through overflow valve 5, and hydraulic cylinder is in lockup state; Certain scale if small piston rod 33 moves right; First hydraulic path 8 in the big piston 7 makes hydraulic cylinder 6 left chambeies be communicated with right chamber; Be that hydraulic cylinder 6 left chambeies equate with the oil pressure in right chamber; Because the area on the big piston left side can know that by F=P*A big piston 7 and big piston bar 9 can move right identical scale, till first hydraulic path 8 in making big piston 7 is sealed again greater than the area on the right; If small piston rod 33 is moved to the left certain scale; Second hydraulic path 29 in the big piston 7 makes hydraulic cylinder 6 left chambeies be communicated with oil-out 24; Be that hydraulic cylinder 6 left chamber oil pressure are zero; Because hydraulic cylinder 6 right chamber oil pressure are greater than left chamber oil pressure, big piston 7 and big piston bar 9 can be to the identical scales of left movement, till second hydraulic path 29 in making big piston 7 is sealed again.Utilization acts on power control action less on the small piston rod 33 bigger power on big piston bar 9, makes the vacuum cup 17 at big piston bar 9 tops accomplish with the adhesive of automobile depression steel plate face, extract work.
Among Fig. 4; Motor 3 makes hydraulic pump 4 that hydraulic oil is pumped into hydraulic cylinder body 6, promotes the certain scale of small piston rod 33 to the right with hand, and second hydraulic path 29 in the big piston 7 make hydraulic cylinder 6 left chambeies be communicated with right chamber; Be that hydraulic cylinder 6 left chambeies equate with the oil pressure in right chamber; Because the area on the big piston left side can know that by F=P*A big piston 7 and big piston bar 9 can move right identical scale, till first hydraulic path 8 in making big piston 7 is sealed again greater than the area on the right.
Among Fig. 5; Motor 3 makes hydraulic pump 4 that hydraulic oil is pumped into hydraulic cylinder body 6, spurs the certain scale of small piston rod 33 left with hand, and second hydraulic path 29 in the big piston 7 make hydraulic cylinder 6 left chambeies be communicated with oil-out 24; Be that hydraulic cylinder 6 left chamber oil pressure are zero; Because hydraulic cylinder 6 right chamber oil pressure are greater than left chamber oil pressure, big piston 7 and big piston bar 9 can be to the identical scales of left movement, till second hydraulic path 29 in making big piston 7 is sealed again.
