Extensively, design, to manufacture the various robots applied in enterprise particularly significant, and the Research on processing technology of part and special fixture are set
Meter is then one of most important technical work in enterprise production process, currently known fixture by setting element, clamping device with
And clamp body is formed by combining, what fixture utilized is regulations and parameters principle, and the arm of force of central point side is multiplied by the power acted on the arm of force,
The power acted on clipped object product is multiplied by equal to other side torque arm length, by the pressure fixing clipped object product of clamping device.But
It is the single article relatively regular mainly for geometry of traditional clamp structure so common fixture abnormity difficult to realize
Being reliably fixed for workpiece special angle installation, falls off and is damaged in process so as to cause robot base, and tradition folder
It is low to have processing efficiency.
Invention content
To achieve the goals above, the present invention provides a kind of fixture, the fixture can effective stationary machines human wrist body,
Conveniently to the milling of robot base upper surface, brill, boring working process.
The technical scheme is that：A kind of special fixture of processing machine human wrist body, the fixture include clamp body,
Clamping device and positioning device, positioning device and clamping device are fixed on clamp body, clamping device include guide post, pressing plate and
Support column, the guide post are fixed on clamp body；The pressing plate is equipped with waist hole, and guide post free end screws in elasticity successively
Part, pressing plate and fastener, guide post pass through pressing plate by waist hole；Support column is used to support pressing plate, is located at one of pressing plate far from workpiece
End, is fixed on clamp body, and the position that the pressing plate is contacted with support column is equipped with guide groove, and pressing plate can supported by guide groove
It is slided on column.
As being further improved for this programme：The clamping device further includes the Thrust nut for preventing guide post from loosening, institute
It states Thrust nut and is located at guide post and is screwed with clamp body and locate top.
As being further improved for this programme：The clamping device further includes the cushion block for preventing pressing plate from wearing, the cushion block
It is located between fastener and pressing plate.
As being further improved for this programme：The positioning device include support plate, positioning pin, at least two support nails and
The support nail mounting plate of fixed support nail, support plate, positioning pin and support nail mounting plate are fixed on clamp body, and support plate is located at
The opposite both sides of clamp body；The positioning pin and the hole of wrist body bottom coordinate.
As being further improved for this programme：The waist hole width, which is more than, is oriented to column diameter no more than 0.5mm.The elasticity
Part is spring.The fastener is nut.
The invention has the advantages that it can be held fixedly robot base, it is convenient that upper end facing cut, brill, boring are processed
Processing, clamps that the location of workpiece is identical every time, and once clamping milling, brill, the boring that can complete to bottom surface, work efficiency is high, folder simple in structure
Tight easy to operate, the stability of fixture service life machining long workpieces is high；Wherein, guide post bottom end is equipped with Thrust nut, can prevent
Guide post loosens；It is equipped with cushion block between pressing plate and fastener, can prevent pressing plate from wearing.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the front view of specific embodiments of the present invention；
Fig. 2 is the left view of Fig. 1；
Fig. 3 is the vertical view of Fig. 2；
1 clamp body, 2 pressing plates, 3 support columns, 4 nuts, 5 cushion blocks, 6 support plates, 7 support nails, 8 support nail mounting plates, 9 in figure
Positioning pin, 10 Thrust nuts, 11 springs, 12 waist holes, 13 guide grooves.
Specific implementation mode
The specific implementation mode of the present invention is described in detail below in conjunction with the accompanying drawings：Facilitate for statement and defines the left sides Fig. 1
For left part, the right is right part, and as shown in Figure 1, Figure 2 and Figure 3, special fixture includes positioning device, clamping device and clamp body, is determined
Position device, clamping device are fixed on clamp body.
Positioning device includes support plate, support nail, support nail mounting plate and positioning pin, as shown in figure 3, support plate is parallel solid
It is scheduled on clamp body bottom plate, in use, workpiece is placed on the supporting plate, limits the three degree of freedom of workpiece；On the right side of clamp body
Portion is fixed with support nail mounting plate, at least two support nails is equipped on support nail mounting plate, in actual use, workpiece abuts
Support nail, two support nail shapes are into a line, limit two degree of freedom；A positioning pin is additionally provided on clamp body bottom plate,
Have the hole with detent fit on workpiece, in actual use, positioning pin is inserted into hole below workpiece, prevent workpiece without limitation forward
Fang Yidong limits the one degree of freedom of workpiece.
As shown in Figure 1,2 and 3, clamping device includes guide post, support column, pressing plate, fastener, elastic component, Thrust nut
