Description
Technical field
The invention belongs to machinery field more particularly to a kind of rotation boosting-type energy-absorbing tube fixing devices.
Background technology
At present in sled impact test, what the fixation of energy-absorbing cylinder mainly or using welding was realized, but welding job is imitated
Rate bottom, and after the completion of collision, it is also necessary to cutting could take off energy-absorbing cylinder, not reproducible utilization.It is set due to needing to weld
It is standby, so can be influenced significantly by place and equipment using traditional welding manner.
A kind of energy-absorbing tube fixing device is disclosed in patent 201510545865.0 and solves the above problem, but is still had
Some defects, for example, one, when energy-absorbing jacket casing is on device, need to insert alignment hexagonal from energy-absorbing cylinder front end with die nut
Sky, because energy-absorbing cylinder may be long sometimes, die nut needs put in very long distance, are difficult to alignment hexagonal in this way
It is empty.Two, energy-absorbing cylinder often will produce serious deformation after collision, can block energy-absorbing cylinder sky completely, such hexagonal is pulled
Hand will be unable to insert from energy-absorbing cylinder front end again, and energy-absorbing cylinder just unloads to get off yet.Three, at present needed energy-absorbing in most cases
What same front port sealed, i.e., with one piece of plate sheet welding in energy-absorbing cylinder front end, such words above-mentioned apparatus will be unable to play a role.
Invention content
To solve the above problems, the present invention provides a kind of rotation boosting-type energy-absorbing tube fixing devices.The present invention solves
The shortcomings that traditional welding fixes energy-absorbing cylinder mode by place and equipment limit, and working efficiency is low, heavy workload, it is proposed that Yi Zhongjian
Single energy-absorbing tube fixing device, simple in structure, functional reliability is strong, repeats and utilizes, and is especially applicable in a variety of different sizes
Energy-absorbing cylinder fixation.
To reach 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 pass through rotating disk and fixed bottom
Disk is fixedly connected, and rotating disk is rotatablely connected with screw axis；Rotatable lamella is rotatablely connected with screw axis, is led between rotating disk and rotatable lamella
It crosses guide rod to be fixedly connected, sliding shoe is threaded on screw axis；Sliding shoe can be slided along guide rod, and sliding shoe is hinged with
One connecting rod, rotating disk are hinged with second connecting rod；First connecting rod and second connecting rod are articulated and connected with tensioning piece.
The rotation side surface is machined with spliced eye, and rotating bar can be inserted in spliced eye, is driven and is rotated by rotating bar
Disk rotates, and the rotation of rotating disk drives the rotation of rotatable lamella by guide rod.
Further, the rotation of guide rod can drive sliding shoe to rotate and slided along screw axis.
Further, respectively there are one guide rods for sliding shoe both sides.
For the first connecting rod as second connecting rod length, guide rod rotation and sliding drive first connecting rod movement, lead to
Cross second connecting rod pushes tensioning piece radially movable together.
Further to improve, the fixed underpan is equipped with screw hole, fixed underpan can be fixed on trolley by screw
On.
The invention has the advantages that：
1. the configuration of the present invention is simple, functional reliability is strong, repeats and utilizes；
2. since shaft orientation moving range is larger in lead screw shaft for movable block, so the device is suitable for the energy-absorbing of different size
The fixation of cylinder；
3. after tensioning, tensioning piece except to energy-absorbing cylinder inner wall there are one radial tensile force in addition to, return one axis of energy-absorbing cylinder
To frictional force, make energy-absorbing cylinder resisting in rotating disk tightly, can prevent energy-absorbing cylinder from travelling forward, Automatic-falling, to make
Energy-absorbing cylinder is fixed more secured..

Specific implementation mode
It is illustrated below by way of specific implementation mode and in conjunction with attached drawing to technical scheme of the present invention.
Embodiment 1
A kind of rotation boosting-type energy-absorbing tube fixing device as depicted in figs. 1 and 2 includes mainly by rotating bar 1, fixed bottom
Disk 2, rotating disk 3, tensioning piece 4, rotational pin 5, first connecting rod 6.1, second connecting rod 6.2, sliding shoe 7, guide rod 8, screw axis 9,
Rotatable lamella 10.
Fixed underpan 2 is fixed on trolley front end by bolts through bolt holes 11 or is directly welded at trolley front end, rotation
Disk 3 is sleeved on screw axis 9, and 9 one end of screw axis is inserted in the hole of fixed underpan 2, and by being welded together, is rotated at this time
Disk 3 can rotate among screw axis 9 and fixed underpan 2, and rotatable lamella 10 is sleeved on screw axis 9, and guide rod 8 passes through sliding shoe 7
Two holes in, and be inserted into 3 corresponding two holes of rotating disk, by being welded to connect, the other end of guide rod 8 is inserted in rotatable lamella
In 10 hole, by being welded to connect, while rotatable lamella 10 is sleeved on 9 the tip of the axis of lead screw, and rotating disk 3 can pass through guide rod 8 and
One connecting rod 6.1 and second connecting rod 6.2 drive rotatable lamella 10 and sliding shoe 7 to rotate together, while sliding shoe 7 is along screw axis 9
Axial direction is slided.First connecting rod 6.1 is articulated and connected by rotational pin 5 and sliding shoe 7, and second liang of bar 6.2 passes through rotation
Pin 5 is articulated and connected with rotating disk 3.Since the rotation of sliding shoe 7 and first connecting rod 6.1, second connecting rod 6.2 and tensioning piece 4 is
Opposing stationary, so the sliding of sliding shoe 7 in an axial direction can drive tensioning piece 4 by first connecting rod 6.1 and second connecting rod 6.2
It is tensioned or is shunk.
Specific implementation process is, first according to the diameter of energy-absorbing cylinder, to rotate rotating disk 3, and tensioning piece 4 is made to be in suitable
Position, then by energy-absorbing jacket casing in tensioning piece 4 outside, and resist the surface of rotating disk 3, rotating bar 1 be inserted into rotate at this time
In the spliced eye 12 of disk 3, rotating bar 1 is rotated, rotating disk 3 is driven to rotate, and then drives sliding shoe 7 to revolve on one side by guide rod 8
Turn the axial direction sliding of an edge lead screw shaft 9, energy-absorbing cylinder is rotated also with sliding shoe at this time, and the axial movement of sliding shoe 7 is led to
It crosses first connecting rod 6.1 and second connecting rod 6.2 pushes tensioning piece 4 to do radial motion, while being rotated also with sliding shoe 7, rotated
During, it is tensioned piece 4 and energy-absorbing cylinder keeps opposing stationary, and then energy-absorbing cylinder is tensioned.
Be tensioned piece 4 except to energy-absorbing cylinder inner wall there are one radial tensile force in addition to, return the frictional force of one axial direction of energy-absorbing cylinder, make
Energy-absorbing cylinder tightly resist rotating disk 3, can prevent energy-absorbing cylinder from travelling forward, Automatic-falling, to make energy-absorbing cylinder fix more
Securely (there is axial friction after tensioning, prevent from falling off), while the energy-absorbing cylinder for being also suitable for different inner diameters is fixed.
The specific guiding embodiment of the present invention is above are only, but the design concept of the present invention is not limited thereto,
All changes for carrying out unsubstantiality to the present invention using this design, should all belong to the behavior for invading protection scope of the present invention.
