Some defects, such as one, when energy-absorbing jacket casing is on device, need to insert alignment hexagonal with die nut from energy-absorbing cylinder front end
Sky, because energy-absorbing cylinder may be long sometimes, die nut needs to put in the longest distance, is thus difficult to alignment hexagonal
Empty.Two, after collision terminates, energy-absorbing cylinder often produces serious deformation, can be blocked completely by energy-absorbing cylinder sky, and such hexagonal is pulled
Hands will be unable to insert from energy-absorbing cylinder front end again, and energy-absorbing cylinder the most just unloads to get off.Three, it is in most cases to need energy-absorbing at present
Same front port seals, and i.e. by one piece of plate sheet welding in energy-absorbing cylinder front end, like this said apparatus will be unable to play a role.
Summary of the invention
For solving the problems referred to above, the invention provides a kind of rotation boosting-type energy-absorbing tube fixing device.The present invention solves
Traditional welding is fixed energy-absorbing cylinder mode and is limited by place and equipment, inefficiency, the shortcoming that workload is big, it is proposed that Yi Zhongjian
Single energy-absorbing tube fixing device, its simple in construction, functional reliability is strong, and repeatable utilization is particularly suitable for multiple different size
Energy-absorbing cylinder fixing.
For reaching above-mentioned technique effect, the technical scheme is that
A kind of rotation boosting-type energy-absorbing tube fixing device, including screw axis, screw axis one end is through rotating disk and the fixing end
Dish is fixing to be connected, and rotating disk is rotationally connected with screw axis；Rotatable lamella is rotationally connected with screw axis, logical between rotating disk and rotatable lamella
Crossing the fixing connection of guide post, threaded on screw axis have sliding shoe；Sliding shoe can slide along guide post, and sliding shoe is hinged with
One connecting rod, rotating disk is hinged with second connecting rod；First connecting rod and second connecting rod are all articulated and connected with tensioning sheet.
Described rotating disk end face is machined with spliced eye, rotates bar and can be inserted in spliced eye, is rotated by rotating bar
Dish rotates, and the guide post that rotates through of rotating disk drives the rotation of rotatable lamella.
Further, the rotation of guide post can drive sliding shoe to rotate and slide along screw axis.
Further, sliding shoe both sides are respectively arranged with a guide post.
Described first connecting rod is the same with second connecting rod length, and guide post rotates and slides and drives first connecting rod to move, logical
Crossing second connecting rod promotes tensioning sheet radially movable together.
Further improving, described fixed underpan is provided with screw hole, by screw, fixed underpan can be fixed on chassis
On.
Present invention have the advantage that
1. present configuration is simple, and functional reliability is strong, repeatable utilization；
2. relatively big, so this device is applicable to the energy-absorbing of different size due to movable block shaft orientation moving range in lead screw shaft
Fixing of cylinder；
3., after tensioning, tensioning sheet, in addition to have a radial direction tensile force to energy-absorbing cylinder inwall, returns one axle of energy-absorbing cylinder
To frictional force, make energy-absorbing cylinder tightly prop up in rotating disk, be possible to prevent energy-absorbing cylinder to travel forward, Automatic-falling so that
Energy-absorbing cylinder is fixing more firm..

Detailed description of the invention
Below by way of detailed description of the invention and combine accompanying drawing technical scheme is illustrated.
Embodiment 1
A kind of rotation boosting-type energy-absorbing tube fixing device as depicted in figs. 1 and 2, mainly includes by rotating bar 1, the fixing end
Dish 2, rotating disk 3, tensioning sheet 4, rotational pin 5, first connecting rod 6.1, second connecting rod 6.2, sliding shoe 7, guide post 8, screw axis 9,
Rotatable lamella 10.
Fixed underpan 2 is fixed on chassis front end by bolts through bolt holes 11 or is directly welded at chassis front end, rotates
Dish 3 is enclosed within screw axis 9, and screw axis 9 one end is inserted in the hole of fixed underpan 2, and by being welded together, now rotates
Dish 3 can rotate in the middle of screw axis 9 and fixed underpan 2, and rotatable lamella 10 is enclosed within screw axis 9, and guide post 8 is through sliding shoe 7
Two holes in, and insert in two holes of rotating disk 3 correspondence, by being welded to connect, the other end of guide post 8 is inserted in rotatable lamella
In the hole of 10, by being welded to connect, rotatable lamella 10 is enclosed within screw mandrel 9 the tip of the axis simultaneously, and rotating disk 3 can be by guide post 8 and the
One connecting rod 6.1 and second connecting rod 6.2 drive rotatable lamella 10 to rotate together with sliding shoe 7, and sliding shoe 7 is along screw axis 9 simultaneously
Axial direction slides.First connecting rod 6.1 is articulated and connected with sliding shoe 7 by rotational pin 5, and second liang of bar 6.2 is by rotating
Pin 5 is articulated and connected with rotating disk 3.Owing to the rotation of sliding shoe 7 and first connecting rod 6.1, second connecting rod 6.2 and tensioning sheet 4 is
Geo-stationary, so the slip that sliding shoe 7 is vertically can drive tensioning sheet 4 by first connecting rod 6.1 and second connecting rod 6.2
Carry out tensioning or contraction.
Specific implementation process is, first according to the diameter of energy-absorbing cylinder, rotates rotating disk 3, makes tensioning sheet 4 be in properly
Position, then by energy-absorbing jacket casing outside tensioning sheet 4, and prop up the surface of rotating disk 3, now rotation bar 1 inserted rotation
In the spliced eye 12 of dish 3, rotate bar 1, dish 3 is rotated and rotates, and then drive sliding shoe 7 to revolve by guide post 8
The axial direction turning an edge lead screw shaft 9 slides, and now energy-absorbing cylinder rotates also with sliding shoe, the axially-movable of sliding shoe 7, logical
Cross first connecting rod 6.1 and second connecting rod 6.2 promotes tensioning sheet 4 to do radial motion, rotate also with sliding shoe 7 simultaneously, rotating
During, tensioning sheet 4 and energy-absorbing cylinder keep geo-stationary, and then by energy-absorbing cylinder tensioning.
Tensioning sheet 4, in addition to have a radial direction tensile force to energy-absorbing cylinder inwall, is returned one axial frictional force of energy-absorbing cylinder, is made
Energy-absorbing cylinder tightly prop up rotating disk 3, be possible to prevent energy-absorbing cylinder to travel forward, Automatic-falling, so that energy-absorbing cylinder is fixing more
Firmly (having axial friction after tensioning, prevent from coming off), the energy-absorbing cylinder being simultaneously also adaptable for different inner diameters is fixed.
Above are only a concrete guiding embodiment of the present invention, but the design concept of the present invention be not limited thereto,
All changes utilizing this design that the present invention carries out unsubstantiality, all should belong to the behavior invading protection scope of the present invention.
