Specific embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing, but this utility model can be according to power
Profit requires that the multitude of different ways for limiting and covering is implemented.
Referring to Fig. 1, Fig. 2, a kind of positioner for copying circle product external of the present utility model, including being arranged at
On workbench and for place the lower clamp 1 and lower clamp of processed product 4 coordinate for clamp processed product 4 and arrange
Above lower clamp, by, binder cylinder drives upper fixture 2 moving up and down and positions for horizontal direction to be added
The positioning fixture 3 of chemical product 4；Lower clamp 1 includes lower chuck 11, and upper fixture 2 includes upper grip 21, and positioning fixture 3 is provided with rank
Terraced through hole, ladder hole include the upper Positioning holes 32 for the lower Positioning holes 31 of the insertion of lower chuck 11 and for processed product insertion,
Upper Positioning holes are coaxially disposed with lower Positioning holes, the diameter with diameter greater than lower Positioning holes of upper Positioning holes, upper Positioning holes and lower positioning
The interface in hole is formed for supporting and position the shoulder 33 of processed product；Positioning fixture 3 is set in lower clamp radial outside
And can be placed on workbench, in the case where manually acting on, positioning fixture individually can be moved up and down along lower clamp；Instantly press from both sides
In 11 insertion lower Positioning holes 31, and processed product 4 is when being placed in upper Positioning holes 32, effect of the upper fixture in upper binder cylinder
Lower drive upper grip 21 is moved towards lower chuck 11, processed product is clamped between upper grip and lower chuck, to complete
Placement product is on positioning collet manually.
In this utility model, processed product is pottery or sapphire product, and its outside diameter is more than 42mm；Lower fixed
Position hole 31 is less than 0.05mm with the fit clearance of lower chuck 11；Upper Positioning holes 32 and the cylindrical fit clearance of processed product 4
It is less than 0.05mm.When the structure setting causes to control product design of the vertical copy machining outside diameter more than 42mm, product
With the concentricity of positioning collet within 0.1mm, it is prevented effectively from and places product off normal manually and the finished product after causing to process occurs
Trimming, subregion is undressed in place etc. bad.Simultaneously so that in the high product of the hardness of the materials such as processing ceramic, sapphire
During product, the allowance of the reserved 0.15～0.2mm of monolateral need of supplied materials product, so as to shorten process time, improves production
