Detailed Description

In order to make the utility model realize the technical means, creation characteristics, achievement purpose and efficiency are easy to understand and understand, which is further explained below.

As shown in fig. 1 to 8, a quick positioning and measuring device for reinforcing a bolt comprises a U-shaped plate 5 matched with the distribution characteristics of a circular hole 1 of a measuring instrument in a working table of a non-contact optical measuring instrument, and an annular frame 4 arranged right above the U-shaped plate 5, wherein the periphery of the annular frame 4 is in interference fit with a positioning pin 8.

Specifically, the U-shaped plate 5 is made of hard aluminum alloy, so that the manufacturing is relatively easy, and the surface is not easy to corrode and rust.

And the U-shaped plate 5 and the circular hole 1 of the measuring instrument are fixedly connected by adopting an inner hexagonal screw 6.

And the right upper part of the U-shaped plate 5 is connected and matched with the annular frame 4 by adopting an outer hexagonal screw 7.

The U-shaped plate 5 carries out material removal treatment on the middle area 11 according to topology optimization, so that the quality is minimized on the premise of meeting the integral function.

The right side area of the U-shaped plate 5 is provided with a right threaded hole 10 fixed with the inner hexagonal screw 6, and the left side area of the U-shaped plate 5 is provided with a left threaded hole 9 matched with the annular frame 4.

Specifically, the U-shaped plate 5 and the non-contact optical measuring instrument platform are fixed by the inner hexagonal screw 6 through a hexagonal wrench, and a gasket is used for increasing the friction force between the surfaces of the U-shaped plate 5 and the non-contact optical measuring instrument platform.

Specifically, the positions of the right threaded hole 10 and the left threaded hole 9 in the U-shaped plate 5 are manufactured according to the position of the measuring instrument round hole 1 in the table top of the optical measuring instrument, the positions are fixed through bolts, and 2 threaded holes are manufactured at the other end of the U-shaped plate 5 and longitudinally fixed with the L-shaped rib.

The annular frame 4 comprises L-shaped ribs 30 and a circular ring 20 which are formed by milling through a machining center.

Two L-shaped rib threaded holes 31 are formed in two ends of the L-shaped rib 30, the size of each L-shaped rib threaded hole is the same as that of the left threaded hole 9, and the L-shaped rib 30 is fixed through the outer hexagonal screws 7.

Specifically, sharp edges of the L-shaped ribs 30 are all subjected to deburring, and are blunted from R1 to R3.

Two rows of round holes of ring 20 evenly distributed all around, including top hole 22 and below hole 21, wherein top hole 22 diameter ratio below hole 21 diameter is little,

top hole

22 and 8 interference fit of locating pin, all carry out the abate processing around top hole 22 and the below hole 21.
