Embodiment
Shape measuring instrument fast-positioning device of the present invention by clamp system, make concentric mechanism, auxiliary body by oneself and constitute
(1) auxiliary body is by outer support 2, and interior bearing 4, support block 6 and steel ball 3 are constituted, and outer support 2 is that other parts are installed
Carrier, there is bearing mounting hole in the bottom center of outer support 2, and the mounting hole bottom hole of outer support 2 has the screwed hole that four circumference are divided equally, outside
There is the mounting hole of support block 6 at the upper surface center of bearing 2, and the mounting hole bottom hole of support block 6 has the screwed hole that two circumference are divided equally, interior bearing
4 mounting holes and the mounting hole of support block 6 are run through by smaller circular hole, have on the lower surface of outer support 2 circumferentially direction have it is equal
The even blind hole being spaced apart, steel ball 3 is arranged in blind hole, and the diameter of steel ball 3 is equal to blind hole diameter, and it is deep that radius value is equal to blind hole
Angle value.
(2) clamp system is by reverse-flighted screw 5, and sliding block 7, knob 1 is constituted, and the centre of reverse-flighted screw 5 is cylindric, and two survey
It is threaded rod, the end of threaded rod is tetragonal body structure, and the center of sliding block 7 is screwed hole, and there are two clamping screwed holes upper surface,
Sliding block 7 is connected to reverse-flighted screw both sides by screwed hole of centre, and there are four square grooves, each face width phase of the groove in the center of knob 1
Deng thering is screwed hole to run through one side of four square grooves on the face of cylinder of knob, knob 1 is connected by the tetragonal body of four square grooves and reverse-flighted screw
Connect, screw is connected knob and reverse-flighted screw by face of cylinder upper screwed hole.
(3) make concentric mechanism by oneself to be made up of claw 8 and support block 6, claw 8 is used cooperatively for a pair, and claw 8 has " V " type face,
