Embodiment: the dental scans instrument tooth die clamper positioner of the present embodiment, comprises pedestal 1 and clamp base 2.As shown in Figure 1 and Figure 2, pedestal 1 is block, and periphery to be connected with two arc-shaped sides by two straight flanges and to surround, and straight flange is relative with straight flange, and arc-shaped side is relative with arc-shaped side.There are a positioning boss 10, three magnet installing holes 11 and three steel ball installing holes in pedestal 1 front.Positioning boss 10 is positioned at pedestal 1 center, the side of positioning boss 10 to be connected with a planar side 16 by a circular arc side 15 and to surround, planar side is parallel with a straight flange of pedestal, the radian of circular arc side 101 is greater than 180 degree, there is guiding surface 17 side of positioning boss 10 and the junction of end face, and namely the side of positioning boss is connected with end face by guiding surface.Three magnet installing holes 11 are centered around the surrounding of positioning boss 10 equably, three magnet installing holes are equilateral triangle distribution, namely three magnet installing holes 11 are each positioned at the drift angle place of equilateral triangle, the center of one of them magnet installing hole 11 is vertical with the planar side 16 of positioning boss 10 with the line at the center of positioning boss 10, and this magnet mounting hole site is in positioning boss planar side side, the magnet 12 with strong magnetic is respectively installed in three magnet installing holes 11.Three steel ball installing holes 13 are near susceptor edges, the spacing of steel ball installing hole 13 and positioning boss 10 is greater than the spacing of magnet installing hole 11 and positioning boss 10, three steel ball installing hole 13 distributions in isosceles triangle, be positioned at the center of the steel ball installing hole 13 at the drift angle place of this isosceles triangle vertical with the planar side 16 of positioning boss 10 with the line at the center of positioning boss 10, and this steel ball mounting hole site is in side, positioning boss circular arc side.Three steel ball installing holes 13 are all shrinkage pools, are respectively provided with positioning ball 14 in three steel ball installing holes, and positioning ball 14 protrudes from pedestal 1 front.Pedestal 1 is connected with the machine shaft of dental scans instrument by three attachment screws 18, the machine shaft of dental scans instrument is connected in the back side of pedestal, three attachment screws 18 are near positioning boss 10, and secondly, steel ball installing hole 13 from positioning boss farthest for magnet installing hole 11.In the present embodiment, pedestal is made up of aluminum material.As shown in Figure 3, Figure 4, clamp base 2 is blocks, and periphery to be connected with a circular arc limit by a straight flange and to surround, and straight flange is less than place, circular arc limit radius of a circle, and in the present embodiment, clamp base employing ferrous material is made.There is a locating hole 20 mated with the positioning boss 10 of pedestal at the center of clamp base 2, the straight flange of locating hole 20 is parallel with the straight flange of clamp base 2, and the straight flange of clamp base 2 is positioned at the side, circular arc limit of locating hole 20, there are three steel ball accommodation holes 21 at the back side of clamp base 2, three steel ball accommodation holes are all spheric shrinkage pool, three steel ball accommodation hole 21 distributions in isosceles triangle, the center being positioned at the steel ball accommodation hole 21 at the drift angle place of this isosceles triangle is vertical with the line at the center of locating hole 20 and the straight flange of locating hole, and this steel ball accommodation hole is between the straight flange and the circular arc limit of locating hole of clamp base, three positioning ball 14 one_to_one corresponding couplings on three steel ball accommodation holes 21 and pedestal, when clamp base and pedestal close, the steel ball part protruding from pedestal front just in time can embed in the steel ball accommodation hole of clamp base.The front of clamp base 2 has the orientation of two limited post 22, two limited posts separately parallel with the straight flange of clamp base, and two limited posts, between the straight flange and the circular arc limit of locating hole of clamp base, limited post 22 have anti-slip veins 23.In the present embodiment, limited post adopts sunk screw, and there are two counterbores at the back side of clamp base, and sunk screw passes and stretches out the front of clamp base from the counterbore at the clamp base back side.The front of clamp base 2 is provided with tooth mould clamping device 3, and the installation site of tooth mould clamping device is relative with the straight flange in clamp base.According to the difference of tooth mould, the structure of tooth mould clamping device is different, explain again for the structure of pressing from both sides upper and lower E Yamo at this, as shown in Figure 5, the tooth mould clamping device be installed in clamp base is the tooth mould clamping device pressing from both sides upper and lower E Yamo, during use, upper and lower E Yamo is placed in clamp base, and between limited post and Ya Mo clamping device, the side of upper and lower E Yamo is pushed up mutually with limited post, rotate the high-head knurling screw on upper and lower E Yamo clamping device, coupled square up and down E Yamo moves, until by upper and lower E Ya die clamp between limited post and Ya Mo clamping device.
Pedestal is arranged on dental scans instrument always, without dismounting under normal service condition.Positioning boss plays guiding positioning action, three are scattered in the steel ball guarantee clamp base of isosceles triangle and the uniqueness in the involutory direction of pedestal, play clamping effect, three magnet being scattered in equilateral triangle provide uniform the suction-combining force simultaneously, by pedestal and clamp base tightly adhesive.Therefore, clamp base can be installed on pedestal easily, and both connections are very firm, as long as and slightly firmly just clamp base can be taken off from pedestal when dismantling, change and dismounting very convenient, time saving and energy saving, be convenient to the clamp base changed with different tooth mould clamping device to press from both sides different tooth mould, and owing to not needing to load and unload any screw when changing, therefore avoid screw well and repeatedly load and unload defect easy to slip teeth, guarantee that dental scans instrument can normally use for a long time, increase the service life.
