Description
Technical field
The utility model relates to frock clamp mechanism technology field, specifically a kind of two pawls centering clamping device.
Background technique
Cylinder material, section are to generally require in the process of equilateral even number bar to different-diameter cylinder and section
Material processing, it is sometimes desirable to be processed into during Taper Pipe and keep the cylindrical center of different-diameter consistent, folder in the prior art
Tight feeding mechanism should not easily lead to Taper Pipe broken end to center, cause production efficiency and product quality not high.
Summary of the invention
In view of the deficiencies of the prior art, the purpose of the utility model is to provide a kind of structure is simple, guarantee different-diameter
Cylinder material, section are the consistent two pawls centering clamping devices of equilateral even number bar machining center.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of two pawls centering clamping device, including clamp body, grip block, guiding axis, upper articulated slab, lower articulated slab, upper hinge
Spindle, intermediate articulated shaft, lower articulated shaft, bearing, grip block include upper grip block and lower grip block, upper grip block and lower grip block
It is connect respectively by guiding axis with clamp body, upper grip block and upper hinged axis connection, upper articulated shaft passes through upper articulated slab and centre
Hinged axis connection, intermediate articulated shaft is by lower articulated slab and lower hinged axis connection, lower grip block and lower hinged axis connection, upper hinged
Axis, intermediate articulated shaft and lower articulated shaft both ends are separately installed with bearing, and clamp body two sides are provided with vertical strip-shaped hole and horizontal bar shaped
Hole, bearing move in vertical strip-shaped hole and horizontal bar hole；
It further include power device, power device is connect by screw with clamp body；
Advantage is the utility model compared with prior art:
The utility model by the cooperation of upper and lower grip block and articulated shaft, articulated slab, by bearing in vertical strip-shaped hole and
Movement in horizontal bar hole drives grip block centered on horizontal bar hole, movement symmetrical above and below, guarantees processing different-diameter
Center during the cylinder material of size is consistent, it is ensured that machining accuracy.
Detailed description of the invention
Fig. 1 is the schematic diagram of internal structure of the utility model；
Fig. 2 is the external structure schematic diagram of the utility model；
Fig. 3 is the lower grip block structural schematic diagram of the utility model；
Fig. 4 is the lower grip block left view of the utility model.
Specific embodiment
The clamping device as shown in Figure 1, a kind of two pawls are felt relieved, including it is clamp body 7-1, grip block, guiding axis 7-2, lower hinged
Plate 7-5, lower articulated shaft 7-4, bearing 7-6, two pawls centering clamping device top are equipped with power device 6, power in the present embodiment
Device 6 is cylinder, and power device 6 is connect by screw with clamp body 7-1, this fixture clamps self-centering, piston using symmetrical
Bar 6-2 is connect by nut 6-3, screw with upper grip block 7-3；Upper grip block 7-3 and lower grip block 7-7 passes through guiding axis 7-2
It is connected with clamp body 7-1, lower grip block 7-7 passes through lower articulated slab 7-5, lower articulated shaft 7-4, intermediate articulated shaft 7-41, upper hinged
Plate 7-51, upper articulated shaft 7-42 are connect with upper grip block 7-3；The lower both ends articulated shaft 7-4 are equipped with bearing 7-6, lower grip block 7-7
Top two sides are provided with level trough 7-71, and the two sides of the bottom upper grip block 7-3 are provided with slot position corresponding with level trough 7-71, clamp body 7-
1 two sides are provided with vertical strip-shaped hole 7-8 and horizontal bar hole 7-9, and bearing is in the vertical strip-shaped hole 7-8 of clamp body 7-1 and horizontal bar shaped
It is moved in the 7-9 of hole.
When work, initial position is that upper grip block and lower grip block separate, and cylinder pushes grip block in piston rod 6-2 pushing
7-3, upper grip block 7-3 since the effect of guiding axis 7-2 can move down, upper grip block 7-3 by upper articulated shaft 7-42, on
Articulated slab 7-51, intermediate articulated shaft 7-41, lower articulated slab 7-5, lower articulated shaft 7-4 and lower grip block 7-7 link, upper, middle and lower hinge
Spindle both ends are respectively provided with bearing 7-6, therefore centre articulated shaft 7-41 can be moved in horizontal bar hole 7-9, upper articulated shaft 7-
42, lower articulated shaft 7-4 can be moved up and down in vertical strip-shaped hole 7-8, due to the position-limiting action of horizontal bar hole, upper articulated slab 7-
51 and lower articulated slab 7-5 is in heeling condition always, and lower grip block 7-7 is by the linkage of articulated slab and articulated shaft with cylinder
Movement, upper grip block 7-3 and lower grip block 7-7 are simultaneously under cylinder action power centered on horizontal bar hole, shifting symmetrical above and below
Dynamic, the cylinder material clamping rear center of such different-diameter is consistent always, ensure that machining accuracy, while improving production efficiency.
The utility model is by the cooperation of upper and lower two pieces of grip blocks and articulated shaft, articulated slab, by bearing in vertical bar shaped
Movement in hole and horizontal bar hole drives grip block centered on horizontal bar hole, movement symmetrical above and below, guarantees that processing is different
Center during the cylinder material of diameter is consistent, it is ensured that machining accuracy.
It is worth noting that the power device of driving two pawls centering clamping device can be cylinder, oil cylinder, screw driven
One kind, bearing 7-6 are also possible to sliding block.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
