Number in the figure is schematically as follows: 1-hollow oil cylinder, and 2-drawing pull bar, the 3-pressure head that leads, 4-moves back and unloads pressure head, 5-backstop, 6-crimping pressure head.
The specific embodiment
Move back and unload frock embodiment
The passenger train positioning arm lining of the present embodiment moves back and unloads frock as shown in Figure 1, comprises that hollow oil cylinder 1, rear end insert hollow oil cylinder 1 drawing pull bar 2 being fixedly connected with the backstop 5 of hollow oil cylinder 1, are sheathed on guiding pressure head 3 in drawing pull bar 2, are fixedly connected on moving back of drawing pull bar 2 front ends and unload pressure head 4; Guiding pressure head 3 can slide in drawing pull bar 2, and its external diameter is less than or equal to the external diameter of positioning arm lining; Move back and unload pressure head 4 and be shaped with one and can hold the counterbore that positioning arm lining enters towards a side of guiding pressure head 3.Guiding pressure head 3 is in the form of annular discs.Move back and unload pressure head 4 and be bolted with drawing pull bar 2, with for convenience detach.
Press-fitting tool embodiment
The passenger train positioning arm bushing press-mounting frock of the present embodiment as shown in Figure 2, comprises that hollow oil cylinder 1, rear end insert hollow oil cylinder 1 drawing pull bar 2 being fixedly connected with the backstop 5 of hollow oil cylinder 1, are sheathed on guiding pressure head 3 in drawing pull bar 2, are fixedly connected on the crimping pressure head 6 of drawing pull bar 2 front ends; Guiding pressure head 3 can slide in drawing pull bar 2; Its external diameter is greater than the external diameter of positioning arm lining.Guiding pressure head 3 is in the form of annular discs.Crimping pressure head 6 is bolted with drawing pull bar 2, with for convenience detach.
Need move back while unloading work, after the passenger train positioning arm bushing press-mounting frock of the present embodiment is installed, need are moved back to the lining unloading to be placed on to move back and to unload between pressure head 4 and guiding pressure head 3 by miniature aluminum alloy hollow oil cylinder, for electronic the automatic control of pump, piston rod is pushed ahead, promote guiding pressure head 3 lining is released, can easily complete the work of unloading of moving back.
In the time of need press-fiting work, only need to disassemble set bolt, by moving back, unload that moving back in frock unloaded pressure head 4 and guiding pressure head 3 is dismantled, be replaced by guiding pressure head 3 and the crimping pressure head 6 of press-fitting tool; Then the lining of needs being installed is placed between guiding pressure head 3 and crimping pressure head 6, and by the propelling of oil cylinder, guiding pressure head 3 and crimping pressure head 6 relatively move, and lining is pressed into.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
