Description
Technical field
The utility model is related to a kind of mechanical processing frock clamps, and in particular to a kind of special-shaped workpiece clamping tooling.
Background technology
In machinery production manufacture field, some parts can be designed to circumference in irregular because of specific demand
The special-shaped workpiece of shape.
When being processed parts with lathe or machining center, need to carry out clamping to parts.Due to abnormity
The circumference of workpiece is complex, and common frock clamp clamping or can not be not easy clamping, it is therefore desirable to dedicated tooling.
But the type due to special-shaped parts and specification are more, existing special tooling can only be realized to specific one kind
Special-shaped workpiece be clamped, versatility is relatively low, it is therefore desirable to which a large amount of tooling causes cost higher.
Utility model content
The purpose of this utility model is：A kind of special-shaped workpiece clamping tooling is provided, it can be achieved that irregular to circumference
The firm clamping of special-shaped workpiece, and versatility is stronger.
To achieve the goals above, the utility model provides the following technical solution：
A kind of special-shaped workpiece clamping tooling, including center connecting shaft and fixture block；The upper end of the center connecting shaft is provided with
Gap, the gap are arranged in decussation, and the upper end lateral wall of the center connecting shaft is provided with screw hole, and the screw hole is in
Circumference array shape arranges that the fixture block connect axis connection with center by fixing screws, the quantity of the fixture block for four and
Gap between fixture block matches with the gap of center connecting shaft upper end, the fixing screws and the screw hole phase in the connecting shaft of center
Coordinate, special-shaped outline, the special-shaped wheel of four fixture blocks are provided at the position of center connection axis in axis on the fixture block
The profile that exterior feature is surrounded is matched with the circumference of special-shaped workpiece.
Further, the lower end inside of the center connecting shaft is provided with internal thread, and lower end outside is provided with linear
Keyway, middle and upper part outside are provided with taper face.
Further, the fixing screws are specially soket head cap screw, quantity and the center connecting shaft of the fixing screws
On screw hole quantity it is consistent.
The beneficial effects of the utility model are：A kind of special-shaped workpiece clamping tooling, fixture block are connected by fixing screws and center
Spindle is connected, and the special-shaped outline of multiple fixture blocks is corresponding, therefore can realize to the irregular special-shaped workpiece of circumference
Firm clamping, and can only be realized to a variety of different sizes or differently contoured special-shaped workpiece into luggage by replacing fixture block
Folder, versatility is stronger, can reduce the quantity required of tooling, reduces production cost.
Description of the drawings
Fig. 1 is a kind of center connecting shaft part drawing of special-shaped workpiece clamping tooling of the utility model.
Fig. 2 is a kind of overall structure diagram of special-shaped workpiece clamping tooling of the utility model.
Fig. 3 is a kind of overall structure diagram of another angle of special-shaped workpiece clamping tooling of the utility model.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the utility model is described in further detail.It should be appreciated that specific embodiment described herein is only explaining this
Utility model is not used to limit the utility model.
With reference to figure 1, Fig. 2 and Fig. 3, a kind of special-shaped workpiece clamping tooling, including center connecting shaft 1 and fixture block 4；In described
The upper end setting of heart connecting shaft 1 has the gap 2, and the gap 2 is arranged in decussation, and the gap 2 is for making center connect
The upper end of axis 1 generates slight elastic deformation in stress, and the upper end lateral wall of the center connecting shaft 1 is provided with screw hole 3, described
Screw hole 3 circumferentially arrange by array-like, and the fixture block 4 is connect by fixing screws 5 with center connecting shaft 1, the quantity of the fixture block 4
Gap between four and fixture block 4 matches with the gap 2 of 1 upper end of center connecting shaft, and elastic shape is being generated for ensureing
Interference is not will produce when change between adjacent fixture block 4, the fixing screws 5 are matched with the screw hole 3 in center connecting shaft 1, institute
It states and is provided with special-shaped outline 6, the special-shaped outline 6 of four fixture blocks 4 at the position of 1 axis of center connecting shaft on fixture block 4
The profile surrounded is matched with the circumference of special-shaped workpiece.
Special-shaped outline 6 on the fixture block 4 can make various shapes, to meet the special-shaped workpiece to a variety of irregular contours
Stabilizing grip, ensure the machining accuracy of special-shaped workpiece.
The lower end inside of the center connecting shaft 1 is provided with internal thread 7, and the internal thread 7 with lathe for connecting, lower end
Outside is provided with linear keyway 8, and the keyway 8 is used to avoid center connecting shaft 1 is opposite with lathe to slide, outside middle and upper part
Side is provided with taper face 9, and the taper face 9 is for making the upper end of center connecting shaft 1 generate slight elastic deformation, to make folder
Block 4 clamps special-shaped workpiece.
The fixing screws 5 are specially soket head cap screw, quantity and the spiral shell in center connecting shaft 1 of the fixing screws 5
The quantity in hole 3 is consistent.
Each fixture block 4 is connect at least through two fixing screws 5 with 1 upper end of center connecting shaft, for ensureing tightness.
When needing another special-shaped workpiece of clamping, fixing screws 5 only need to be backed out with tool, change corresponding fixture block 4
And fix, versatility is stronger, while saving the cost for needing multiple center connecting shafts 1.
The utility model is not confined to these by above-described embodiment for being further described to the utility model
Specific implementation mode.All any modification, equivalent and improvement made within the spirit and principle of the present invention etc.,
It is interpreted as being within the protection scope of the utility model.
