Description
Technical field
The present invention relates to milling machine technical field, more particularly to pneumatic scroll chuck.
Background technology
Auto parts and components such as universal joint, wheel hub, piston workpiece, just metalworkings by forging, heat treatment, after ball blast
Treatment, wherein rim technique is carried out on milling machine.Rim be by piece-holder on the chuck of milling machine, cut by milling cutter
Milling.The chuck of prior art generally comprises two dog chucks, scroll chuck；Claw is slidably connected with the deck in chuck body；It is logical
Cross cylinder or cylinder movement drives claw move toward one another, clamping workpiece.
The bare terminal end of traditional claw is generally planar or the conical surface, and, in clamping workpiece, end gives workpiece table for it
The pressure in face is larger, easy disfiguring workpiece；In addition, for the processing such as work of universal joint, wheel hub, piston with curved surfaces
Part, bare terminal end is that plane or its clamping face of the claw of the conical surface are smaller, and firm grip is unstable, and in rim, claw holds with workpiece
Fallibility displacement is moved.
The content of the invention
The present invention is in view of the shortcomings of the prior art, there is provided a kind of to clamp stabilization, reduce claw to the pneumatic of the damage of workpiece
Scroll chuck.
The present invention realizes solving above-mentioned technical problem by following technological means：A kind of pneumatic scroll chuck, including card
Disk body, three claws；Three claws be arranged in the chuck body and in the chuck body slide match somebody with somebody
Close；Described three two claws are distributed in herringbone, and the angle between two neighboring claw is 120 °：Each claw includes sliding
Dynamic portion, corpus unguis portion；The corpus unguis portion includes bare terminal end, connection end；The connection end in the corpus unguis portion is detachable with the sliding part
Connection, the bare terminal end in the corpus unguis portion is in the arc-shaped caved in；Cave in region and two sides of bare terminal end of the bare terminal end
Between formed first be connected region, second linking region；The first linking region, the second linking region bend in opposite directions, are formed
Arcuate structure.
Preferably：The first screw-threaded counterbore is offered on the connection end in the corpus unguis portion, is offered on institute's sliding part
One tapped blind hole, the first bolt is provided with first screw-threaded counterbore, the first tapped blind hole.
The advantage of the invention is that：Invention is set in arc-shaped, when three by by the region of caving in of the bare terminal end of claw
Claw is clamped to round piece simultaneously when, the bare terminal end of multiple claws is drawn in form circular cavity in opposite directions, and workpiece is wrapped up to sky
In chamber, holding area is on the one hand improve, increase clamping fastness；On the other hand reduce because plane or conical surface clamping are to work
The damage that part brings.Using being detachably connected between sliding part, the corpus unguis portion of claw of the present invention, can be for different workpiece more
Change different corpus unguis.Further, since during claw draws in, bare terminal end is attached on the surface of workpiece, the depression area of bare terminal end
If being connected region wedge angle between domain and clamping end side surface, then workpiece can be scratched；And linking region of the invention is arc knot
Structure, in clamping process, it is to avoid nib contacts, effectively prevents workpiece from scratching.
Brief description of the drawings
Fig. 1 be pneumatic scroll chuck of the invention be arranged on chuck body when structural representation.
Fig. 2 is the partial enlarged drawing of Fig. 1 of the present invention.
Fig. 3 is the structural representation of claw of the invention.
Fig. 4 is the structural representation of the claw of the sliding part with dovetail groove in the present invention.
Specific embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
A part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
As shown in Figure 1-2, the present invention discloses a kind of pneumatic scroll chuck, including 4, three claws of chuck body；Described three
Individual claw be arranged in the chuck body 4 and be slidably matched in the chuck body 4；Described three two claws are in
Herringbone is distributed, and the angle between two neighboring claw is 120 °：Each claw includes sliding part 1, corpus unguis portion 2；Corpus unguis portion 2
Including bare terminal end, connection end；The connection end in corpus unguis portion 2 is detachably connected with sliding part 1, and the bare terminal end in corpus unguis portion 2 is in what is caved in
Arc；The formation two between region 212 and two sides 211 of bare terminal end of caving in of bare terminal end is connected region 213；Two linkings
Region 213 bends in opposite directions, forms arcuate structure.
The present invention sets in arc-shaped the region 212 of caving in of claw bare terminal end, when three claws are simultaneously to round piece
During clamping, the bare terminal end of multiple claws is drawn in form circular cavity in opposite directions, and workpiece is wrapped up into cavity, on the one hand improves folder
Area is held, clamping fastness is increased；On the other hand reduce because of the damage that plane or conical surface clamping bring to workpiece.The present invention
Using being detachably connected between sliding part 1, the corpus unguis portion 2 of claw, the different corpus unguis of different workpiece replacings can be directed to.Separately
Outward, during being drawn in due to claw, bare terminal end is attached on the surface of workpiece, cave in region 212 and two sides of bare terminal end
If between linking region wedge angle, then can scratch workpiece；And linking region of the invention is arcuate structure, in clamping process
In, it is to avoid nib contacts, effectively prevent workpiece from scratching.
As shown in Figure 1,3, in some embodiments：Block 3 is provided with sliding part 1, block 3 is contacted with corpus unguis portion 2.
During actually milling is cut, power, milling cutter particularly when motor cut milling intensity it is larger when, the company between corpus unguis portion 2 and block 3
Fitting can loosen, and cause the floating of the angle of corpus unguis portion 2, influence its clamping effect.The present invention is set by sliding part 1
There is block 3, when there is the trend of turn in corpus unguis portion 2, corpus unguis portion 2 is kept out effect by block 3, can effectively alleviate its rotation
It is dynamic.
In some embodiments：Block 3 is circumscribed with corpus unguis portion 2.
In some embodiments：Be provided with the arcuate structure for caving on block 3, the end of the connection end in corpus unguis portion 2 with
Arcuate structure is engaged.During clamping, block 3 forms local clad structure with the end of the connection end in corpus unguis portion 2, further, has
Effect prevents the turn of corpus unguis portion 2.
As shown in figure 4, in some embodiments：Sliding part 1 include the leading flank that is connected with corpus unguis portion 2 and with chuck
The trailing flank of the connection of slide 4；Trailing flank offers dovetail groove.It is swallow-tailed when sliding part 1 is fastened on the slide 4 of chuck
Trough body structure, can be preferably mutually chimeric with slide 4.
As shown in Fig. 1,4, in some embodiments：The first screw-threaded counterbore, second are offered on the connection end in corpus unguis portion 2
Screw-threaded counterbore, offers the first tapped blind hole on institute's sliding part 1, and is provided with the first screw-threaded counterbore, the first tapped blind hole
One bolt 5.The second tapped blind hole is provided with the slide 4 of chuck, second is provided with the second screw-threaded counterbore, the second tapped blind hole
Bolt 6.
In sum, the present invention has clamping stabilization, reduces technique effect of the claw to the damage of workpiece.
