Description of the drawings
Fig. 1 is the side view of the torque transmission mechanism in specific implementation mode；
Fig. 2 is the partial sectional view of the torque transmission mechanism.
Specific implementation mode
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawings.
Fig. 1 is the side view of the torque transmission mechanism in specific implementation mode；Fig. 2 is the part of the torque transmission mechanism
Sectional view.
As shown in Figure 1, 2, torque transmission mechanism 100 has the shaft coupling 1 for connecting spanner, passes through key on shaft coupling 1
Connection is mounted on the upper end of force application rod 2 (force application part), and by spline, (lower end periphery face is formed with the lower end 2a of force application rod 2
Spline) connection is on the upper end cover 3 (inner peripheral surface of upper end cover 3 is formed with corresponding spline) of sleeve part 4, sleeve part
The lower end of part 4 is installed with bottom end cover 5, tightening sleeve 6 (tightening connector) is fixedly mounted on bottom end cover 5, tightening sleeve 6 is for twisting
Clamping of workpieces.Wherein, 3 inner circumferential of upper end cover is inserted into the lower end of force application rod 2, and the peripheral surface of force application rod 2 divides on the inner peripheral surface of upper end cover 3
It is not formed with mutually matched spline structure.So that torsion can be passed to upper end cover 3 by force application rod 2 in the circumferential, but two
Person can relatively move in the axial direction.
In addition, being received in sleeve part 4, equipped with pressure head 13, (in present embodiment, pressure head 13 is separate structure, has top
Structure and the lower structures being fixed thereon), pressure head 13 is mounted on the interior of sleeve part 4 by upper and lower a pair of of ball bearing 12
Circumferential surface, and can move up and down.The upper surface of pressure head 13 is pushed down on by the lower face of force application rod 2 by thrust bearing 10
(axial push), i.e. force application rod 2 are connect through thrust bearing with pressure head 13 can relatively rotate, push away in the axial direction in the circumferential
The mode of pressure pressure head 13 connects.
In addition, being installed with action handle 7 on force application rod 2, action handle 7 is driven by driving mechanism (not shown) (such as cylinder)
And it moves up and down.A pair of bearings 9 up and down is installed, force application cylinder 2 is equipped with shaft shoulder portion and spacing ring 8 between action handle 7 and force application rod 2
(not shown), shaft shoulder portion are located at 9 lower section of bearing of downside, and spacing ring is located at the top of the bearing 9 of upside, so, it is possible to limit
The relative movement (preventing about 2 play of force application rod) of force application rod 2 and action handle 7 drives force application rod 2 to move up and down by action handle 7,
Entire mechanism can be made to move up and down and pushing force is applied to pressure head 13.
The tightening to the torque transmission mechanism 100 of present embodiment for tightening fuel injector tight cap of oil nozzle (workpiece) below
Action when operation illustrates.
First, driving mechanism (cylinder) action handle 7 moves down and then entire torque transmission mechanism 100 is made to decline, until
Pressure head 13 completely compresses oil nozzle (drives oil nozzle to make oil nozzle and spray when can prevent from tightening by oil nozzle and oil injector body compression completely
Oily body produces relative rotation).
Shaft coupling 1 is screwed by spanner later, the rotation of shaft coupling 1 by force application rod 2, upper end cover 3, sleeve part 4, under
End cap 5 passes to tightening sleeve 6.
In addition, using the characteristic (two pieces of spline can move axially, but be unable to circumferential relative motion) of spline, in early period
During slowly tightening, when six side of the inside of tightening sleeve 6 is identical as six square degree of tight cap of oil nozzle, by dead weight, tightening sleeve 6
Can be sleeved in tight cap of oil nozzle automatically, and with the progress of tightening operation, tightening sleeve 6 can with tight cap of oil nozzle slowly together under
Drop, without departing from.Torsion is required until being tightened to.
In tightening operation, action handle 7 pushes down on pressure head 13 by force application rod 2, thrust bearing 10, will be oily by pressure head 13
Mouth compresses.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
For example, in the above-described embodiment, 13 periphery of pressure head is sleeved on as the tightening sleeve 6 for tightening connector, pressure head 13 via
The inner circumferential of tightening sleeve 6 compresses workpiece,, can be with according to the actual conditions of workpiece however, the utility model is not limited to this
It is that pressure head is sleeved on the structure for tightening connector periphery.
In addition, in the above-described embodiment, force application rod 2 is realized by spline that can transmit in the circumferential with upper end cover 3
Torsion, the mode that can be relatively moved in the axial direction connect, however, the utility model is not limited to this, can replace spline, if
Other holding sections that fastens, can be moved in axial direction in the circumferential are set, such as the pin of radial arrangement is set on force application rod 2,
Longer slot hole in the axial direction that correspondingly setting coordinates with pin on upper end cover 3.
