Embodiment
Specific embodiment of the present utility model is further detailed below in conjunction with the accompanying drawings.
The stopper structure for adapting to engine line upstream rotation member positioning lifting stroke as shown in Figures 2 and 3
And its application state signal, horizontal cylinder 2, the cylinder connection of cylinder 2 are provided with the left of the frame structure of stopper main body 1
The front end of bar 3 is provided with roller bearing follower 5, and roller bearing follower 5 is placed on roller backing plate 4, two be arranged symmetrically piece
Servo-actuated clamping plate 8 is positioned at through rotating shaft 16 on the framework of stopper main body 1, is servo-actuated the curved surface 18 and roller bearing follower 5 of clamping plate 8
Roll surface be in contact, because curved surface 18 is non-horizontal surface, so in the telescopic process of cylinder 2, in roller bearing follower 5 by the right side
During advancing to the left, pass through its roll surface leaning to curved surface 18 so that it is applied with an active force to servo-actuated clamping plate 8
On, and then servo-actuated clamping plate 8 is rotated clockwise along its rotating shaft 16, and then the servo-actuated left part quilt of clamping plate 8 can be caused
Lifting, on the contrary, can also be by controlling cylinder 2 to decline the servo-actuated left part of clamping plate 8.It is attached on corresponding servo-actuated clamping plate 8
Part is also servo-actuated in the lump.
As illustrated, rotating bar 11 is located in the position of the servo-actuated left upper portion of clamping plate 8 by rotating shaft 17, rotating bar 11
Top, which is provided with, stops roller 13, is additionally provided with torsion spring 12 so that rotating bar 11 has the trend to turn clockwise or effect
Power.Buffer 6 is a hydraulic cushion oil cylinder, and it is fixed on servo-actuated clamping plate 8 by buffer mounting blocks 7, what it was provided
Cushion task face can be acted in the torque arm of the bottom of 11 rotating shaft of rotating bar 17.
Wherein, rotating bar 11 is provided in the space bit between two pieces of servo-actuated clamping plates 8, in the opposite side of two servo-actuated clamping plates 8
Stop arm 10 is respectively provided with panel, the top of stop arm 10 is provided with roller 15, and the rotating shaft of roller 15 is with stopping roller 13
Rotating shaft 17 it is parallel, and stop that the highest order of its roll surface when going to highest order of roller 13 is lucky in the rotation process of rotating bar 11
Can be concordant with the highest order holding of the roll surface of roller 15, in the case of no applied external force, stop the counter roller of roller 13
15 are closer to engine source direction side.
When engine advances in roller line, the piston of cylinder 2 is in contraction state, and cylinder 2 is rolled by cylinder connecting rod 3
Sub- bearing follower 5；At this moment the lower edge for being servo-actuated clamping plate 8 abuts against the outer rim of roller bearing follower 5, peace under gravity
Rotating bar 11 on servo-actuated clamping plate 8 keeps a kind of static tensile under the effect of the mutual elastic force of torsion spring 12 and buffer 6.When
When stop roller 13 in rotating bar 11 contacts with engine tray 14, under the frictional force effect of roller-way roller, hair
Motivation pallet moves on.Now, engine tray needs to overcome the resistance of buffer 6, can be by adjusting hydraulic bjuffer sheet
The elastic force of body, also it can reach a suitable buffering effect by adjusting buffer nut come the position of mobile cushioning device.
Such as a states in Fig. 3, by engine direction of advance, circulation part --- the engine tray on assembly line
14 start to contact and extrude with the stop roller 13 of rotating bar 11, when causing roller 15 of the pallet in the stop arm 10, that is, transport
Row b states, engine tray 14 into Fig. 3 halt.After engine tray 14 enters cold trial work position, cold test stand frame is to it
Positioning lifting is carried out, pallet now abuts the roller 15 being arranged in stop arm 10 and the stop roller 13 of rotating bar 11 is upward
Mobile, until pallet is kept completely separate with stopper, now the stop roller 13 of rotating bar 11 is in the presence of (hydraulic pressure) buffer 6
Rotate down；When cold test stand frame is completed to test, pallet declines, and pallet connects during decline with the roller 15 in stop arm 10
Touch, even if pallet pushes the stop roller 13 in rotating bar 11, will not also advance forward, so as to complete the essence of the action
It is determined that position.Hereafter, the piston of cylinder 2 forward extends out, and is servo-actuated clamping plate 8 under gravity along the outer of roller bearing follower 5
Edge moves down, until stop arm 10 abuts shock absorbing polyurethane 9, that is, runs the c states into Fig. 3.Engine tray 14 is crossed
Stopper moves under the frictional force effect of roller-way roller, flows to next station.So far, stopper complete buffering,
The everythings such as stopping, clearance.
