The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment, structure, feature and effect thereof to according to the nut closing in grip device that the utility model proposes are described in detail as follows:
Embodiment 1:
Referring to Fig. 1,2,3,4,9, two processing nut closing in grip devices, comprise tapered sleeve (1), panel (2), chute dish (3), pressure head (4), pressing plate (5), spring pressed stud (6), positioning element (7), spring (8) composition.Chute dish (3) is fixed on panel (2) end face, pressing plate (5) is fixed on chute dish (3) end face, positioning element (7) is fixed on chute dish (3) center hole, pressure head (4) is two, evenly distribution is installed in the groove of chute dish (3), mounting spring is pressed nail (6) and spring (8) in the pressure head, spring pressed stud (6) end face contacts with positioning element (7), and pressure head (3) rear end fillet compresses with the conical surface of tapered sleeve (1) and contacts.
Embodiment 2:
Referring to Fig. 5,6,9, three processing nut closing in grip devices, pressure head (4) is three, evenly distribution is installed in the groove of chute dish (3).All the other are with embodiment 1.
Embodiment 3:
Referring to Fig. 5,6,9, four processing nut closing in grip devices, pressure head (4) is four, evenly distribution is installed in the groove of chute dish (3).All the other are with embodiment 1.
Referring to Figure 10, among the embodiment 1-3, pressure head 4 also can be elliptic closing in pressure head.
Feature and effect thereof: two to four local conical surfaces at tapered sleeve (1) conical surface oblique angle are formed by the cutting of branches such as the complete conical surface, wherein big inclined-plane is the F.F./regression journey of pressure head, this trip can be accelerated movement velocity in the pressure head idle stroke (promptly do not contact with the closing in nut stroke) to increase work efficiency, and enlarge the stroke of pressure head so that when the clamping of pressure head (4) workpiece (closing in nut) when retreating, and little inclined-plane is the impulse stroke that pressure head (4) worker advances, this moment, pressure head (4) speed was slower, and the moment when increasing work, improved the closing in quality effectively.
Pressure head (4) is packed in the slotted eye of chute dish (3), on pressure head (4), install pressing plate (5) additional, pressing plate (5) is fixed with bolt and chute dish (3) end face, positioning element (7) is fixed by bolts in chute dish (3) center hole, pressure head (4) hole built-in spring is pressed nail (6) and spring (8), spring pressed stud (6) contacts with positioning element (7), by spring force pressure head (4) is pressed to the dish outside, panel (2) is packed in chute dish (3) the excircle step and is connected and fixed with bolt, tapered sleeve (1) is fixed with bolt and drive unit, tapered sleeve (1) conical surface passes the slotted eye of chute dish (3) and panel (2), after equipment installed, pressure head (4) rear end fillet should contact with the conical surface of tapered sleeve (1).
Pressure head (4) axial displacement in the slotted eye that chute dish (3) and pressing plate (5) form is limited, because effect pressure head (4) the rear end fillet of spring force and the conical surface of tapered sleeve (1) compress.
When driver element drives tapered sleeve (1) when moving upward, pressure head (4) carries out radial motion to chute dish (3) center under the acting in conjunction of tapered sleeve (1) and spring (8), the front end of pressure head this moment (4) makes nut be subjected to the radial compression effect, thereby realizes the closing in of nut.
When driver element drives tapered sleeve (1) when moving downward, under spring (8) effect, the conical surface that pressure head (4) presses tapered sleeve (1) along chute dish (3) radially outward away from nut, a fabrication cycles is finished.
