Specific embodiment
It is a specific embodiment of invention below, invention is described further now in conjunction with attached drawing.
As shown in Figures 1 to 4, a kind of major diameter root key jacking mechanism, basic framework 1 are rectangular frame structure, upper end
Equipped with connector, for quickly connecting with host, host can control major diameter root key jacking mechanism and provide high pressure for it
Oily power.Basic framework 1 is mainly including upper junction plate, four vertical pillars being connected under upper junction plate, and is connected to four
Pedestal 4 under a vertical pillar, pedestal 4 are provided with the sliding slot 4-1 of upward and downward；Slide mass 3 is slidably mounted on the sliding slot of basic framework 1
It is interior, the through-hole passed through for slide mass 3 is provided in the middle part of pedestal 4, pedestal 4 can be passed through by guaranteeing that slide mass 3 slides up and down.In slide mass
3 top is equipped with the mounting bracket that is fixedly connected with basic framework 1, be separately installed at left and right sides of mounting bracket one group it is vertical
Oil cylinder 2, vertical 2 lower end piston rod of oil cylinder are connect with slide mass 3；Vertical oil cylinder 2 is mobile for controlling slide mass 3, to adjust cunning
The relative position up and down of kinetoplast 3 and basic framework 1.3 lower part of slide mass is equipped with three groups of water along the arrangement of 3 vertical direction of slide mass
Flat oil cylinder；Every group of cross cylinder includes two, is respectively symmetrically mounted at left and right sides of 3 lower part of slide mass.This three groups of cross cylinders
Stepped from the bottom to top, the distance stretched out to two sides successively increases.3 front and rear sides of slide mass are respectively fixed with one vertically
Locating rod 3-1；Sensor 8 for detecting locating rod 3-1 stroke is installed in the mounting bracket on basic framework 1.Water
Flat oil cylinder can position the position of slide mass 3 by sensor 8 when driving slide mass 3 to glide, also it is ensured that sliding
The cross cylinder of body 3 can be parked in scheduled position, the every group of cross cylinder and prefabricated 5 water of key being accurately positioned in slide mass 3
It is flat concentric.By three groups of cross cylinders, successively pushing tow is mixed in 5 keys to stake holes wall of prefabricated key, and it is biggish to solve cross cylinder
Stroke demand and the limited problem of installation space；Three groups of cross cylinder movements are more steady, improve the level of prefabricated key 5 with one heart
Degree.Each side being provided with deep gouge a 4-1, two deep gouge 4-1 in the lower end surface of pedestal 4 is across 4 through hole center of pedestal；
