Description
Technical field
The present invention relates to the clamping technical field of workpiece, in particular to a kind of fixed device of movable loop.
Background technique
In manufacturing, some equipment can use non-removable nested type movable loop assembly, as shown in Figure 1,
The movable loop 2 that such assembly generally comprises main body lantern ring 1 and is movably nested on the thin diameter section 11 of main body lantern ring 1, activity
Lantern ring 2 can not be removed from main body lantern ring 1, but can carry out axial activity relative to main body lantern ring 1；Some movable loops 2
Inner hole further include major diameter section 21 and path section 22.
This assembly is usually directly to be processed by machining apparatus, and when processing can be fixed by main body lantern ring 1
On machining apparatus；During movable loop 2 processed in assembly, first the major diameter section 21 of movable loop 2 can be added
Work molding, then again cuts off the connecting portion between movable loop 2 and main body lantern ring 1, and in order to avoid in cutting movable sleeve
Occur when the connecting portion of ring 2 and main body lantern ring 1 forge a knife, vibration deformation the problems such as, need to make movable loop 2 and main body lantern ring
1 is relatively fixed, in addition, when the inner wall of the subsequent path section 22 to movable loop 2 is further processed, it is also desirable to make
Movable loop 2 and main body lantern ring 1 are relatively fixed.
Summary of the invention
The object of the present invention is to provide a kind of fixed devices of movable loop, for making non-removable nested type movable loop
Movable loop and main body lantern ring in assembly is relatively fixed.
To achieve the above object, the fixed device of movable loop provided by the present invention uses following technical scheme:
The movable loop fixes device
Anchor ear, for banding in main body lantern ring；
At least two fixing pieces, for fixing movable loop, fixing piece is moved along the radially-directed of anchor ear and is assemblied on anchor ear, Gu
Determine the stretching portion for the inner hole surface that part has for stretching movable loop, the stretching portion of each fixing piece, which cooperates, realizes movable loop
The fixation of opposite main body lantern ring；
Thread, is rotatably assorted with fixing piece and the radial direction along anchor ear and fixing piece are relatively fixed, at the same also with anchor ear screw thread
Cooperation, to realize the locking of fixing piece and anchor ear；Alternatively, thread and anchor ear are rotatably assorted and along the radial direction and anchor ear of anchor ear
It is relatively fixed, while being also threadedly engaged with fixing piece, to realize the locking of fixing piece and anchor ear.
The beneficial effect of the fixed device of movable loop provided by the present invention is: the fixed device of the movable loop passes through anchor ear
Realize the fixation with main body lantern ring, the fixing piece stretching movable loop being then assemblied in by least two guiding movements on anchor ear
Inner hole surface, and by thread realize fixing piece and anchor ear locking, to realize the phase of movable loop with main body lantern ring
To fixation.
Further, fixing piece includes and the sliding block of anchor ear guiding cooperation and the stretching block being arranged on sliding block, stretching block
When in use towards the shape adaptation of the side of movable loop inner hole surface and movable loop inner hole surface, side constitutes the support of fixing piece
Tight portion；The sliding slot that sliding block is equipped with adaptation is corresponded on anchor ear.The structure of the fixing piece of this form is relatively simple, and convenient for guiding
It is assemblied on anchor ear.
Further, size of the stretching block in the circumferential direction of anchor ear is greater than size of the sliding block in the circumferential direction of anchor ear.In this way
It is arranged so that the contact area of the inner hole surface in the stretching portion and movable loop of fixing piece is larger, can not only increases movable loop
Stability, but also the probability of damage of the fixing piece to the inner hole surface of movable loop can be reduced.
