Specific embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
All other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model of present invention protection
Enclose.
Fig. 1-Fig. 4 is referred to, the embodiment of the present invention includes：
A kind of 4 × 90 ° of automatic transposition apparatus of right-angle head, including：Right-angle head casing 21 and ram component 1, ram component 1
It is interior it is concentric be equipped with main shaft 4, main shaft 4 is connected by connecting shaft 12 with power transmission shaft 3, power transmission shaft 3 by a bolt mechanism with it is straight
Angle head casing 21 is connected, connection of being intermeshed between the ram component 1 and right-angle head casing 21.
Two states can be realized using the automatic transposition apparatus, one kind is that in normal operation, main shaft 4 voluntarily turns
Dynamic state.It, when indexing is needed, is to need directly to drive right-angle head casing 21 to rotate by main shaft 4 that another kind is, realizes automatic turning
The state of position.
Main shaft 4 is connected by straight end-face key 10 with a tapered sleeve 9, is connected by flat key 6 between the tapered sleeve 9 and connecting shaft 12,
The one end of the connecting shaft 12 is fixedly connected with power transmission shaft 3, and the other end is provided with a main blind rivet inside main shaft 4 at the top of it
2, it is connected with main shaft claw 7 on the main blind rivet 2.4 are provided with the outer surface of right-angle head casing 21 of the contact of ram component 1
Individual secondary blind rivet 5, claw is respectively connected with the secondary blind rivet 5.
The main shaft claw 7 is that, by three hydraulic oil cylinder drivings, the claw of 4 secondary blind rivets 5 is driven by 4 pull head oil cylinders 8, described
Pull head oil cylinder 8 is fixed on ram component 1.
The bolt mechanism is freely up and down slided in the right-angle head casing 21, by a latch 17 that can only be moved left and right with
Power transmission shaft 3 is connected.
As shown in Fig. 2 when system is connected to indexing instruction, main shaft 4 stops operating, 4 pull head fuel tanks control 4 secondary blind rivets
Claw on 5 is opened so that secondary blind rivet 5 can easily remove claw, and three oil cylinder control main shaft claws 7 advance downwardly a row
Journey, drives connecting shaft 12 and right-angle head casing 21 to move downwardly together.
Now, the position of the tapered sleeve 9 being fixed in ram component 1 is constant, and tapered sleeve 9 is fixed in the one end of the spring assembly 11
Interior, the other end is supported on right-angle head casing 21, and the position for causing tapered sleeve 9 by the spring assembly 11 remains constant.
Bolt mechanism also upward sliding while ram component 1 is raised, latch 17 locks power transmission shaft 3；When main shaft oil cylinder
Move into place, after system receives feedback signal, main shaft 4 starts to rotate, and motion is transmitted to tapered sleeve 9, tapered sleeve 9 by straight end-face key 10
By flat key 6, motion is transmitted to connecting shaft 12, then drives power transmission shaft 3 to rotate, power transmission shaft 3 transmits motion by latch 17
To right-angle head casing 21, the indexing of right-angle head casing 21 is finally realized.
As shown in figure 1, after completing indexing, three oil cylinder control main shaft claws 7 pull up main blind rivet 2, the He of connecting shaft 12
Right-angle head casing 21 is moved up, and ram component 1 is engaged with right-angle head casing 21.Engage simultaneously, bolt mechanism slide downward；Insert
Pin 17 unlocks power transmission shaft 3, and 4 claws tense secondary blind rivet 5, and main shaft 4 realizes normal work.
Wherein, bolt mechanism includes pad first 15, pad axle 18, pin 19 and compression spring 16,18 sets of the pad axle
In pad first 15, and pad first 15 is fixedly connected with pad axle 18 by screw, the compression spring 16 is located at pad
First 15 lower section, the pad axle 18 is connected by pin 19 with latch 17, and the pad axle 18 is further opened with guide 17 or so
Mobile oblique kidney slot, it is therefore an objective to which the latch 17 connected by pin 19 can be moved left and right.
As shown in figure 4, being provided with a gap 20 between its middle press pin first 15 and pad axle 18, the gap 20 is for adjusting
The size of coupling mechanism force is saved, gap 20 is worth bigger, and coupling mechanism force is smaller, conversely, coupling mechanism force is bigger.
The operation principle of bolt mechanism is：Using compression spring 16, the present invention preferably cylindroid helical-coil compression spring 16 to
On restoring force, drive latch 17 move right, so as to lock power transmission shaft 3.
When indexable, the upward sliding in the presence of compression spring 16 of pad first 15, drive pad axle 18 and pin 19 together to
Upper slip, pin 19 is slided along the kidney slot of pad axle 18, drives latch 17 to move right, so as to power transmission shaft 3 be locked；
During 4 normal work of main shaft, pad first 15 is depressed by ram component 1, promotes pad axle 18 to move down, pin 19 along
The kidney slot of pad axle 18 is slided, and drives latch 17 to be moved to the left, so as to disengage power transmission shaft 3.
The surrounding of right-angle head casing 21 is laid with least 4 convex key blocks 14, and ram component 1 is provided with to be nibbled with convex key block 14
The recessed key block 13 closed, nibbling for right-angle head casing 21 and ram component 1 is capable of achieving by the engagement of convex key block 14 and recessed key block 13
Close.
4 × 90 ° of automatic transposition apparatus simple structures of right-angle head of the invention, reduce the design difficulty of right-angle head, cost
It is low, improve the practicality of product；Increased retaining mechanism, it is possible to reduce workman changes the time of head, improve production efficiency, and
Help to realize automating.
