Embodiment:
Below in conjunction with accompanying drawing and embodiment fixture for pressing shaft of the present invention is done further explain:
As shown in Figure 2, in this embodiment, fixture for pressing shaft of the present invention comprises guiding core body 3, cylinder body 11 and the slip ring 7 and the slide block 6 that are arranged in cylinder body 11 inner chambers 13.Guiding core body 3 is provided with the guide slide 5 that power supply machine rotating shaft 2 is passed through; Inner chamber 13 perisporiums are provided with lubricating oil, and slip ring 7 periphery walls can slide up and down along inner chamber 13 perisporiums under the effect of lubricating oil, and slide block 6 is positioned at the through hole that slip ring 7 middle parts are provided with; Through-hole wall is provided with lubricating oil; Slide block 6 can slide up and down at the effect lower edge of lubricating oil through hole, and guiding core body 3 is positioned at slip ring 7 and slide block 6 tops, and guide slide 5 is positioned at slide block 6 tops; Being connected with between slip ring 7 and slide block 6 and the cylinder body 11 can avoid machine shaft 2 to be upsetting or diastrophic protection mechanism; This protection mechanism comprises left back-moving spring 16, upper left connecting rod 17, left lower link 15, left waling stripe 14, right waling stripe 12, upper right connecting rod 8, bottom right connecting rod 10, middle vertically connecting rod 18 and right back-moving spring 9, and upper left connecting rod 17 tops and slip ring 7 are hinged, and be hinged between upper left connecting rod 17 bottoms, left lower link 15 tops and left waling stripe 14 left parts; Left side lower link 15 lower hinge are in cylinder body 11 inner chambers 13 bottoms; Left side back-moving spring 16 left ends are connected with cylinder body 11 inner chambers 13 sidewalls, and left back-moving spring 16 right-hand members are connected with left lower link 15, and are hinged between left waling stripe 14 right parts, middle vertically connecting rod 18 bottoms and right waling stripe 12 left parts; Middle vertically connecting rod 18 tops and slide block 6 welding; Hinged between right waling stripe 12 right parts, upper right connecting rod 8 bottoms and bottom right connecting rod 10 tops, upper right connecting rod 8 tops and slip ring 7 are hinged, and connecting rod 10 lower hinge in bottom right are in cylinder body 11 inner chambers 13 bottoms; Right back-moving spring 9 left ends are connected with bottom right connecting rod 10, and right back-moving spring 9 right-hand members are connected with cylinder body 11 inner chambers 13 sidewalls.
Operation principle of the present invention is: cylinder body 11 is installed on the hydraulic press lower table (not shown); Protection mechanism in cylinder body 11 inner chambers 13 is when initial; Because the acting in conjunction of left back-moving spring 16, left waling stripe 14, right waling stripe 12 and right back-moving spring 9, upper left connecting rod 17 is in vertical state, promptly same vertical line position with left lower link 15 and upper right connecting rod 8 with bottom right connecting rod 10; At this moment then be the dead point of protection mechanism, slip ring 7 is can be to lower slider with slide block 6.When the workman assembled machine shaft 2, the workman at first need be buckled in guiding core body 3 tops with rotor 4, and makes the lining 1 and guide slide 5 coaxial lines that is embedded on the rotor 4; Pressure F through hydraulic press upper table (not shown) is pressed into machine shaft 2 in the lining 1 at last; After machine shaft 2 bottoms reach accurate installation dimension L, when promptly slide block 6 is run in machine shaft 2 bottoms, the hydraulic press if the workman does not also have enough time to turn-off; Machine shaft 2 bottoms will push slide block 6 to lower slider under the effect of hydraulic press upper table pressure; At this moment, left waling stripe 14 and right waling stripe 12 will drive upper left connecting rod 17, left lower link 15, upper right connecting rod 8 and 10 rotations of bottom right connecting rod under the ordering about of the vertical connecting rod 18 in centre, at this moment; Slip ring 7 will be with slide block 6 synchronously to lower slider; Thereby the rotor 4 that drives guiding core body 3 and be positioned on the guiding core body 3 moves down with machine shaft 2, and then has avoided machine shaft 2 to be upsetting or flexural deformation, has guaranteed the precision of installation dimension L.
