Embodiment
The embodiment of the present invention is described in detail with reference to the accompanying drawings.
Fig. 1 is the side view of the torque transmission mechanism in embodiment；Fig. 2 is the partial cutaway of the torque transmission mechanism
View.
As shown in Figure 1, 2, torque transmission mechanism 100 has the shaft coupling 1 for being used for connecting spanner, passes through key on shaft coupling 1
Connection installed in the upper end of force application rod 2 (force application part), the bottom 2a of force application rod 2 by spline (lower end periphery face formed with
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, and tightening sleeve 6 (tightening joint) is fixedly mounted on bottom end cover 5, and tightening sleeve 6 is used to twist
Clamping of workpieces.Wherein, the lower end insertion inner circumferential of upper end cover 3 of force application rod 2, the outer peripheral face of force application rod 2 on the inner peripheral surface of upper end cover 3 with dividing
The not spline structure formed with mutual cooperation.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 Split type structure, has top
Structure and the lower structures being fixed thereon), pressure head 13 is arranged in sleeve part 4 by upper and lower a pair of ball bearings 12
Side face, and can move up and down.The upper surface of pressure head 13 is pushed down on by the lower surface of force application rod 2 by thrust bearing 10
(axial push), i.e. force application rod 2 connect through thrust bearing can in the circumferential relatively rotate, push away in the axial direction with pressure head 13
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 drive mechanism (not shown) (such as cylinder)
And move up and down.A pair of bearings 9 up and down is installed, force application cylinder 2 is provided 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 the lower section of bearing 9 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 (prevent force application rod about 2 play) of force application rod 2 and action handle 7, drives force application rod 2 to move up and down by action handle 7,
It can move up and down whole mechanism and pushing force is applied to pressure head 13.
The tightening to the torque transmission mechanism 100 of present embodiment exemplified by tightening fuel injector tight cap of oil nozzle (workpiece) below
Action during operation illustrates.
First, drive mechanism (cylinder) action handle 7 moves down and then declines whole torque transmission mechanism 100, until
Pressure head 13 completely compresses oil nozzle (drives oil nozzle to make oil nozzle and spray when compressing oil nozzle and oil injector body can prevent from tightening completely
Oily body produces relative rotation).
Shaft coupling 1 is screwed by spanner afterwards, the rotation of shaft coupling 1 passes through force application rod 2, upper end cover 3, sleeve part 4, lower end
Lid 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 stage
During slowly tightening, when the side of inside six of tightening sleeve 6 is identical with the square degree of tight cap of oil nozzle six, by deadweight, tightening sleeve 6
Can be enclosed on automatically in tight cap of oil nozzle, 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, by pressure head 13 by oil
Mouth compresses.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
For example, in the above-described embodiment, the periphery of pressure head 13 is enclosed on as the tightening sleeve 6 for tightening joint, pressure head 13 via
The inner circumferential of tightening sleeve 6 compresses to workpiece, however, the present invention is not limited thereto, can be pressure according to the actual conditions of workpiece
Headgear is tightening the structure of joint periphery.
In addition, in the above-described embodiment, force application rod 2 is realized that can transmit in the circumferential with upper end cover 3 by spline
Torsion, the mode that can be relatively moved in the axial direction connect, however, the present invention is not limited thereto, can replace spline, set it
The holding section that he fastens, can moved on axial direction in the circumferential, for example, on force application rod 2 set radial arrangement pin, upper end
Elongated hole longer in the axial direction coordinated with pin is correspondingly set on lid 3.
