The rotation latch 47 is horizontal on 46 upper surface of inserted block after in 45.Rotating latch 47, it can prevent inserted block 46 upward
It is detached from, plays position-limiting action, after completing processing, as long as rotary motion latch 47 can cancel limit.
As shown in figures 1 to 6, the working principle of the present embodiment is as follows:
The arc panel 7 being connected on tie down screw 5 is previously inserted into box body hole, then by two on cabinet lower surface
A hole a2 is aligned with vertically oriented column and is fixed on vertically oriented column, has quenching layer, Yi Jiwei in the upper end of vertically oriented column
Limit convex shoulder below quenching layer, limits its positioning that can play upper and lower position of convex shoulder.
And the inserted block 46 being connected on tie down screw 5 then inserts in locating notch 45, is matched by the tool on tie down screw 5
External member 6 is rotated against inserted block 46 and relative to inserted block 46, and the rear side that can drive tie down screw 5 to fixed bottom plate 1 at this time is mobile, this
When transmission bracket 71 arc panel 7 and box body hole can be forced to be in close contact relative to the rotation of tie down screw 5, it is then sleeping on milling machine
Formula milling cutter b is contacted with cabinet stabilizer blade and is carried out Milling Machining.
After Milling Machining, tool auxiliary equipment 6 is reversely rotated, arc panel 7 and box body hole at this time, which is cancelled, to be in close contact, even
It is upwardly separated from together with cabinet and tie down screw 5 and finally dismantles cabinet.
As Figure 7-8,
There are two annulus to limit support frame 53 for rotation connection on tie down screw 5, and annulus limits support frame 53 and is located at two pieces
Between arc panel 7, and there are spacing on the periphery of the inner wall of arc panel 7 and annulus limitation support frame 53.
Two annulus limitation support frames 53 are located on the outside of the both ends of fixing sleeve 51.
The annulus limitation support frame 53 of design can prevent arc panel 7 voluntarily inwardly opposite close, that is, play limit in the limit
Bit function.
It includes inner ring that annulus, which limits support frame 53, and inner ring is connect by the extension rod that several even circumferentials are distributed with outer ring.
Specific embodiment described herein is only an example for the spirit of the invention.The neck of technology belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
