Description
Technical field
This utility model relates to a kind of clamping device, particularly to a kind of fast clamping device of workpiece.
Background technology
Use screws clamp very universal in manufacturing industry, but how to shorten the rotation distance of screw, shorten processing
Non-cutting time, improving work efficiency, but there's sth behind all this can do.
The clamp body 3 currently used uses screws clamp, and its structure is as it is shown in figure 1, add on clamp body 3
Four screwed holes of work, are respectively mounted four and hold out against screw 2；Owing to workpiece to be machined positioning end is relatively big, at handle
When workpiece 1 is put in clamp body 3, it is necessary to hold out against screw 2 four and screw out, workpiece could be put into, work
Behind part location, then screwing in holding out against screw, the back-out holding out against screw screws in distance, consumes a large amount of auxiliary
Time, reduce working (machining) efficiency.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in construction, clamps convenient Quick-clamped
Device.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
A kind of fast fixture, including:
One is arranged on the fixed cover on clamp body, and the cylindrical of described fixed cover is provided with ladder boss, fixed cover
Centre is provided with a hole, the inwall in described hole is arranged with and extends keyway, described hole interior along hole length direction
Portion is provided with the escape for two keyways of processing；
One is arranged on the slip swivel nut in fixing trepanning, and a tapped through hole is offered at the middle part of described slip swivel nut,
Being arranged with two convex keys on one end cylindrical of described slip swivel nut, other end cylindrical is provided with along slip swivel nut
The external screw thread that circumferencial direction extends；
One is set in the back-moving spring on slip swivel nut；
One may be rotatably mounted at the housing screw in tapped through hole；
One is arranged on the back-up ring on slip swivel nut external screw thread.
In an embodiment of the present utility model, described fixed cover and clamp body interference fit.
In an embodiment of the present utility model, described housing screw is provided with locking nut.
By technique scheme, the beneficial effects of the utility model are:
Owing to this utility model housing screw does not expose in clamp body, so workpiece can be put into smoothly
Go；Furthermore, housing screw only needs little rotation, so that it may workpiece pressing, because originally relying on screw to rotate
Distance, achieve now by the slip between fixed cover and slip swivel nut, so the time is greatly shortened,
Achieve Quick-clamped.

Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be readily apparent from effect
Understand, below in conjunction with being specifically illustrating, this utility model is expanded on further.
See shown in Fig. 2 to Fig. 7, the utility model discloses a kind of fast fixture and include fixed cover 100
With the slip swivel nut 200 being arranged in fixed cover 100.
Fixed cover 100 is arranged on clamp body 400, and with clamp body 400 relatively tight fit (interference fit),
The cylindrical of fixed cover 100 is provided with ladder boss 110, and during work, ladder boss 110 can bear pressure,
Avoiding fixed cover to skid off from clamp body, be provided with a hole 120 in the middle of fixed cover 100, slip swivel nut 200 is pacified
Put in this hole 120, be slidably matched between the two, the inwall in hole 120 is arranged with along hole length direction
Extending keyway 130, the inside in hole 120 is provided with the escape 140 for two keyways of processing.
A tapped through hole 210 is offered at the middle part of slip swivel nut 200, and housing screw 260 may be rotatably mounted at spiral shell
In stricture of vagina through hole 210, one end cylindrical of slip swivel nut 200 is arranged with two convex keys 220, convex key 220
With keyway 130 matched in clearance on fixed cover, other end cylindrical is provided with and extends along slip swivel nut circumferencial direction
External screw thread 230, external screw thread 230 is provided with back-up ring 240, slip swivel nut is arranged with back-moving spring 250,
The effect of back-up ring 240 is fixed reset spring 250, prevents back-moving spring 250 from deviating from.
Shown in Figure 6, it is now releasing orientation, workpiece 300 can be called in clamp body 400,
Owing to now housing screw 260 does not expose in clamp body, so workpiece can put in smoothly；When
Workpiece is after clamp body inner position, with hand push housing screw 260, housing screw drive slip swivel nut 200 to
In move, compression spring 260 is slided inwards simultaneously, beyond solid inside the convex key 220 of slip swivel nut 200
Surely, during set inner face, rotate 90 degree, unclamp palm, under the effect of back-moving spring 250, slip swivel nut
Convex key inside with the end contact of fixed cover, rotate housing screw, by workpiece pre-tightening, tighten locking nut.
Shown in Figure 7, it is now impaction state, the rotation that 260 need of housing screw are little, so that it may
Workpiece pressing, because originally relying on the distance that housing screw rotates, now by fixed cover 100 and slip spiral shell
Slip between set 200 achieves, so the time is greatly shortened, it is achieved that Quick-clamped.
Work pieces process is complete, unclamps locking nut 270, slightly rotates housing screw 260, then use palm
Push housing screw 260, drive slip swivel nut 200 to rotate together, make the convex key 220 of slip swivel nut return to
During keyway 130 position of fixed cover, unclamp palm, under the effect of back-moving spring 250, slip swivel nut 200
Release together with housing screw 260, revert to releasing orientation.
Rely on housing screw rotation to realize workpiece pre-tightening and the segment distance unclamped due to original, change into by cunning
Between movable snail sleeve and fixed cover, quick sliding realizes, and has therefore saved the time.Achieve fast-holding and unclamp.
Of the present utility model ultimate principle and principal character and of the present utility model excellent have more than been shown and described
Point.Skilled person will appreciate that of the industry, this utility model is not restricted to the described embodiments, above-mentioned reality
Execute and principle of the present utility model is simply described, without departing from this utility model spirit described in example and description
On the premise of scope, this utility model also has various changes and modifications, and these changes and improvements both fall within
In the range of claimed this utility model.This utility model claims scope by appending claims
And equivalent defines.
