Specific embodiment
One embodiment of plane and two pits positioning device is as shown in Fig. 1 ~ Fig. 3, including positioning table 1 and is integrally disposed upon respectively
Upper positioning pin and lower positioning pin on the upper and lower table top of positioning table 1, upper and lower positioning pin is coaxial and structure snd size are identical.With
For upper positioning pin, it is made of many tooth valves 4 being uniformly distributed along the circumference, and has gap, each tooth between adjacent tooth valve 4
The root of valve 4 is integrally connected to form a whole tooth root, and the junction of whole tooth root and positioning table 1 offers ring
Connected in star 5, the setting of annular groove 5, which is equivalent to, reduces the thickness of whole tooth root, to be conducive to the change of each tooth valve 4
Shape, elasticity are relatively good.
Circular hole 2 is offered between two adjacent tooth valves 4 on whole tooth root, the setting of circular hole 2 is equivalent to each
The root width of tooth valve 4 reduces, to be more conducive to the deformation of tooth valve 4.It is found by test of many times, in order to be compared
Excellent deformation performance, the height of tooth valve 4 are preferably the 2/5 of entire plane and two pits positioning device height, the center of circular hole 2 to ring
5 height of connected in star are preferably the 1/10 of entire plane and two pits positioning device height.
The shape and size of each tooth valve 4 be it is identical, each tooth valve 4 tool it is flexible so that tooth valve 4 with positioning
It can deform under the extruding of location hole hole wall after the cooperation of hole and be interference fitted with location hole, i.e., what is be made of multiple tooth valves 4 is outer
Circumferential surface and location hole are interference fitted, the value of interference fit be it is micro, the damage of workpiece is caused to prevent excessive interference fit.
The tooth top of each tooth valve 4 curves inwardly and forms bending section, the bending starting point of the bending section and bending section
The line on top and vertical angle are 20 degree, and all bending sections come closer, in this way in the tooth valve structure forms of receipts can be with
Good protection formed to tooth valve 4, when use when carrying out the cooperation with location hole, the top of tooth valve 4 will not be caused to damage,
It ensure that using effect and service life, while ensure that positioning accuracy.In addition, the tooth valve structure form of interior receipts can also generate
One guiding role, allows positioning pin and location hole to be quickly and accurately positioned cooperation, so that structure is simple, easy to use.
The facewidth that tooth valve 4 removes remaining vertical portion outside bending section is consistent, and the facewidth of each bending section is from top to bottom
It is not consistent, but is in up-narrow and down-wide shape, if being arranged in this way, as tooth valve 4 is by the extruding of location hole hole wall, tooth
After valve 4 is deformed inward, the side in adjacent flex portion can be bonded to each other, the top of each bending section can piece together a circular hole, tooth valve 4
Top be equivalent to and be deformed into an entity with rigidity, tooth valve 4 following in this way would not deform again, in this way
Setting be equivalent to tooth valve 4 be provided with a deformation limit, prevent when in use, excessive deformed damaged tooth valve 4, while
It is to give one using standard, i.e., if positioning device with location hole when cooperating, tooth valve is by appropriate deformation, discovery positioning
Pin is still difficult to be inserted into location hole, that just illustrates that positioning device is not matched with location hole, is replaced.
The left and right sides of positioning table 1 further respectively has the screw hole 3 for assembling lifting pin screw 7, and screw hole 3 is countersunk head
The setting in hole, counter sink can guarantee that the head of screw of lifting pin screw 7 will not expose screw hole 3, to guarantee positioning device just
It is often used.
The working principle of plane and two pits positioning device is as shown in Fig. 2 ~ Fig. 3: in use, first assembling lifting pin screw 7
In screw hole 3, the effect of lifting pin screw 7 is, when removing positioning device, can use lifting pin screw 7 for entire plane and two pits
Positioning device is easily taken out from the groove on fixture 9.After assembling lifting pin screw 7, by two plane and two pits positioning dresses
It sets 6 to be placed on fixture 9, and is interference fitted the location hole on lower positioning pin and fixture 9, fluted, positioning is opened up on fixture 9
Platform 1 is just embedded in the groove, and the upper surface and the upper surface of fixture 9 of positioning table 1 are just concordant.Then each one side
Two pin positioning device for use 6 are all fixed on fixture 9 by two pressing plates 8, in addition, being located at two plane and two pits positioning in fixture 9
The two sides up and down in 6 middle position of device are also respectively fixed with a pressing plate 8, and six pressing plates 8 together constitute and are used to support workpiece
10 supporting element.Workpiece 10 is finally placed on to the top of pressing plate 8 and plane and two pits positioning device 6, makes the location hole of workpiece 10
It is interference fitted with upper positioning pin, so far just completes the positioning of workpiece 10 Yu fixture 9.
Since location hole interference of the upper and lower positioning pin respectively with workpiece 10 and fixture 9 of plane and two pits positioning device 6 is matched
It closes, tooth valve 4 deforms so that not having any gap between positioning pin and location hole, to improve positioning accuracy.In addition, adopting
Cooperated with two plane and two pits positioning devices 6 and workpiece 10 and fixture 9, two plane and two pits positioning devices 6 limit workpiece 10
It around the rotation of Z-direction, and repeats to limit workpiece 10 and is moved along X, Y-direction, the freedom degree for repeating limitation further improves
The positioning accuracy of workpiece 10, so as to improve machining accuracy.
In the other embodiments of plane and two pits positioning device: the structure snd size of upper and lower positioning pin can not be identical, than
If the quantity of its outer diameter, height and tooth valve can be different, according on workpiece and fixture location hole size and required bullet
Property power can adjust accordingly；It can be the structure type of tooth valve with only one in upper and lower positioning pin, and another is still existing
Solid construction form in technology, can adjust according to the needs of use；Upper and lower positioning pin can not be with positioning table integrally to be set
It sets, such as can be to be weldingly fixed on positioning table after separately fabricated；The line on the bending starting point of bending section and bending section top with
Vertical angle may be 15 degree or 18 degree；The height of tooth valve may be the 2/ of entire plane and two pits positioning device height
3, it can adjust accordingly according to actual needs；Screw hole can also be not provided on positioning table；Annular groove is arrived at the center of circular hole
The 1/9 of height or entire plane and two pits positioning device height, can adjust accordingly according to actual needs；On whole tooth root
Circular hole can not also be opened up between two adjacent tooth valves；The junction of whole tooth root and positioning table can also be not provided with annular
Groove；The tooth root of each tooth valve, which can not be, is integrally connected into a whole tooth root, for example, each tooth valve can individually with positioning
Platform is connected；The facewidth of each bending section be also possible to from top to bottom it is consistent, at this time with the deformation of tooth valve, the top in adjacent flex portion
End can contact with each other；By adjusting the shape in gap and tooth valve between each tooth valve, after the deformation of tooth valve, adjacent flex portion can also
It need not contact with each other；The shape and size of each tooth valve can not also be identical.
