Description
Technical field
The utility model belongs to nib processing technique field, the positioner on especially a kind of nib process equipment.
Background technology
At present, positioning for converted products is can't do without in automated machine processing, mechanical processing and positioning slowly from fixed manually
Automatic location is arrived in position, and positioner has generally comprised holder in the prior art, and holder is typically made up of two intermediate plates, and two
Individual intermediate plate realizes relative motion by the driving of actuator, i.e., mutually closes up or be separated from each other the clamping of corresponding pen clip and release folder
Hold, existing structure has some following deficiency, is formed first, being harmonious by two holding pieces, extruding is not in time or firmly not easy enough
Cause nib to be processed to fall, easily cause abrasion to produce polishing scratch the outer surface of nib again if extruding is excessive, influence attractive in appearance
And production, it is deep mixed second, the depth that nib is fallen into after holder is uncontrollable, increase difficulty to processing, and structure compared with
Complexity, it is unfavorable for producing.
The content of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of the more firm of clamping, simple in construction, operation
Convenient nib processing and positioning device.
To achieve these goals, the technical solution adopted in the utility model is：A kind of nib processing and positioning device, including
Holder, holder include at least two panels holding piece, the clamp area being adapted to nib, the holder are provided between holding piece
Outer peripheral face on be arranged with centring ring, centring ring and holder expansion fit, the outer peripheral face flue of the holder, clamping
Part moves up and down the clamp area opening and closing movement for forming holding piece along centring ring, and being provided with the clamp area between the holding piece can
Movable thimble, the limited block for preventing thimble from dropping is equipped with holder, the both ends of limited block extend outwardly through positioning respectively
Circle, limited block form spacing setting with centring ring.
In above-mentioned technical proposal, holder and centring ring is are coaxially disposed, and holder is relative to slide with centring ring, folder
It is horn-like that the outer peripheral face of gripping member is that internal diameter gradually increases from inside to outside, when centring ring has extruding to holding piece, i.e. holder
When the direction being gradually reduced towards internal diameter is moved, clamp area is in clamp position, when extruding of the centring ring releasing to holding piece, that is, presss from both sides
During the direction movement that gripping member gradually increases towards internal diameter, clamp area, which is in, releases clamp position, the exterior contour and nib of clamp area
Exterior contour adaptation, be circle, preferable holding piece be three into triangular structure, because triangular structure is most stable of
Geometry, clamping can be made more firm, simple in construction, centring ring is evenly distributed and fixed to the chucking power of holding piece, avoids
Abrasion to nib outer peripheral face, improves product quality, rate of reducing the number of rejects and seconds, and the effect of thimble is the nib that limitation is fallen into clamp area
Number, ensure only have a nib fall into clamp area, the pilot hole passed through for limited block is provided with holder, limited block can
Be oriented to and slide along pilot hole, limited block is also located on centring ring, can prevent centring ring from rotating, avoid holder outer peripheral face and
Friction is produced between the inwall of centring ring, is increased the service life.
Further set as of the present utility model, one end of the holder is bare terminal end, and the other end is connection end, even
Connect and be threaded with fixture on end, be provided between fixture and the bottom surface of centring ring on the outer peripheral face for being set in holder
Elastic component, the elastic force of elastic component drive holder clamp area is closed up in folder toward the direction movement that bare terminal end is stretched into centring ring
Hold station.
In above-mentioned technical proposal, elastic component can be that cylindrically coiled spring, special helical spring and shell fragment etc. are flexible
Part, fixture can be nut, and fixture forms removable threaded connection with holder, because elastic component is set in fixation
Between part and the bottom surface of centring ring, holder can be connected to admittedly respectively along the axially directed sliding of centring ring, the both ends of elastic component
Determine on part and centring ring, when fixture and centring ring are mutually drawn close, elastic component is compressed, and the bare terminal end of holder passes positioning
Circle, clamp area is set to open in clamp position is released, the elastic component after being compressed has individual elastic thrust to fixture and centring ring,
It is located remotely from each other fixture and centring ring, the bare terminal end of holder stretches into centring ring, clamp area is closed up in clamp position, side
Just clamp area toggles between clamp position and contact clamp position, simple in construction, and operating efficiency is high.
Further set as of the present utility model, the elastic component is butterfly spring.
In above-mentioned technical proposal, disk spring coning plate-like, both can be with used aloned, again as sealing auxiliary member
It can be used with multiple serial or parallel connections, the either statically or dynamically load acted on vertically is born at upper inner edge and lower outer rim, is pressed
It is deformed after contracting, until being driven plain, to store form of energy as changing load, is automatically converted to when necessary required for sealing
Additional compression load, to reduce the lasting requirement of pad, filler to tightening in, reduce unnecessary fault power time
And leakage loss, multiple butterfly springs are used in preferable the design, increase elastic force, clamp clamp area more firm.
Further set as of the present utility model, the through hole passed through for holder, through hole are provided with the centring ring
Inwall be the wedge shape that be adapted to holder outer peripheral face, the maximum outside diameter of holder is more than the maximum inner diameter of through hole, the clamping
Air-vent is provided with part outer peripheral face, air-vent connects with clamp area, and the number of air-vent is consistent with the number of holding piece.
In above-mentioned technical proposal, because the port outside diameter of bare terminal end is more than the internal diameter of through hole, so some is clamped all the time
End be it is exposed outside through hole, ensure centring ring have extruding force to bare terminal end in moving process, if the external diameter of bare terminal end port with
The internal diameter of through hole is equal or is less than, then is moved regardless of centring ring, centring ring does not all have extruding force, air-vent to bare terminal end
Setting can mitigate the overall weight of clamping device, also holder and centring ring can produce air-flow when mobile, these gas
If shunting can hinder the movement of holder and centring ring to stream not in time, so the setting of air-vent also has the effect of shunting, make
Air-flow caused by movement can be gone out by timely water conservancy diversion, holder and centring ring is moved more smooth, the number of air-vent and clamping
The number of piece is unanimously that outward appearance is also more good-looking in order to easy to process.
Using such scheme, by the relative movement between holder and centring ring, come realize clamp area clamp position and
The switching between clamp position is released, the setting of elastic component makes the switching efficiency of clamp area higher, effectively reduces energy consumption, saves life
Cost is produced, improves competitiveness, simple in construction, easy to process, installation and removal are easily quick.
The utility model is further described below in conjunction with the accompanying drawings.
