First piston 5 is driven by first handle 8 and screw rod 7 and realizes moving left and right in oil cylinder overcoat 4, and the second piston 14 is driven by second handle 19 and cone valve 9 and realizes moving left and right in the first lining 12.By the position of adjustment screw thread blanking cover 16, the setting of spring 15 pretightning force can be realized, thus realize the adjustment of supporting force size.Working chamber 21 of the present utility model, lock chamber 6 and oil cylinder chamber 22 form the space of a sealing in respective line, for storing hydraulic oil.
Below in conjunction with accompanying drawing, a use procedure of the present utility model is described.
As shown in Figure 1, before work, because spring 15 has certain pretightning force, promote the second piston 14 and be moved to the left, ensure that cone valve 9 is in opening; When first piston 5 moves right, original oil pressure in oil cylinder chamber 22 is very little, be not enough to resilient sleeve 3 is deformed, hydraulic oil enters working chamber 21 by the gap between wedge 24 and the second lining 18, promote expansion bearing 2 to move upward, the second piston 14 can not move right because spring 15 has certain pretightning force.
When expansion bearing 2 rises the part encountered and need processing, stop rising, realize conformal function.Now, pressure increase in working chamber 21, because passage 23 is connected with air, second piston 14 moves right under the effect of pressure differential, and Compress Spring 15, drive wedge 24 to contact with the second lining 18, realize closing valve events, now, the hydraulic oil in oil cylinder chamber 22 can not enter working chamber 21.
When first piston 5 continues to move right, the pressure increase in lock chamber 6, now, resilient sleeve 3 produces micro-deformation, is located by expansion bearing 2 banding, so far achieves the reliable supporting location of expansion bearing 2.
When needing unloading, be moved to the left by first piston 5, the pressure drop in oil cylinder chamber 22 and lock chamber 6, resilient sleeve 3 deformed state disappears, and expansion bearing 2 hooked state is removed; When oil cylinder chamber 22 is equal with working chamber 21 pressure, expansion bearing 2 is in critical condition; When the pressure in oil cylinder chamber 22 is less than working chamber 21, cone valve 9 is moved to the left under negative pressure state, cone valve 9 is in opening, hydraulic oil enters oil cylinder chamber 22 from working chamber 21, second piston 14 is under the promotion of spring 15, be moved to the left, expand the open gap of cone valve 9 further, hydraulic oil enters the increased flow capacity in oil cylinder chamber 22 from working chamber 21; When the pressure of working chamber 21 is less than atmospheric pressure, expansion bearing 2 moves down under differential pressure action, and the second piston 14, under same pressure differential, is moved to the left, and can not move, complete whole uninstall process until spacing.
