When the radius of the endoporus of the outer arc curvature of a curve radius of sector segment and chuck body is inconsistent, the soft band of built-in wear-resisting and in described sector segment outer wall and the formed slit of chuck body inwall by location glue blind.
Form two sector segment mounting grooves in the described chuck body between per two fixed blocks, between two sector segments voussoir is installed, fixed block and voussoir are staggered at same sagittal plane.
Be close to solid screw between described chuck body and the fixed block and be connected and fixed, chuck body and fixed block joint are equipped with junction of the edges of two sheets of paper screw, and junction of the edges of two sheets of paper screw and trip bolt are perpendicular.
The preparation method that the present invention proposes is that the grinding segment chuck body is resolved into two bodies, processing respectively, recombinant together, the slit between grinding segment and the chuck body is with wear-resisting soft band and location glue filling.
May further comprise the steps according to above-mentioned installation detent mechanism preparation method of the present invention:
1) chuck body and fixed block are processed respectively, and endoporus, the cylindrical with chuck body adopts turning process to be machined to given size earlier, boring;
2) rough-cast with prefabricated fixed block becomes an annulus, after inside and outside circle is machined to given size, the annulus line is milled into several fixed blocks, drilling and tapping;
3) fixed processing is carved piece to requiring size, drilling and tapping;
4) fixed block is installed on the chuck body, adjust the mounting groove size of sector segment after, trip bolt makes fixed block and chuck body be fixed as one;
5) when the outer arc curvature of a curve radius of sector segment is consistent with the radius of the endoporus of chuck body, can directly in the grinding segment groove, sector segment be installed, voussoir is placed between two sector segments, carry out fastening with the voussoir screw;
6) if when the outer arc curvature of a curve radius of the radius of curvature of chuck body endoporus and sector segment is inconsistent, finish the 4th) after the step, built-in wear-resisting band in sector segment outer wall and the formed slit of chuck body inwall, do mould with sector segment, be full of the slit with location glue, make its radius of curvature corresponding, again voussoir is placed between two grinding segments with grinding segment, carry out fasteningly with the voussoir screw, adjust the back sector segment chuck body that finishes and complete.
The present invention has replaced traditional sector segment that location technology and structure are installed, and this technology is used in vertical surface grinding machine with round table is produced, and has solved the difficulty of processing chuck body and has eliminated potential safety hazard, has improved working (machining) efficiency simultaneously, has shortened the production cycle greatly; The mounting groove of sector segment changes turning processing into by original slotting processing, solved of the requirement of slotting processing chuck body to the technological equipment precision, farthest reduced difficulty of processing, can guarantee processing and positioning accuracy better, the installation rigidity of sector segment is improved, guaranteed the safety in utilization of lathe.The inventive method rapid and convenient can all satisfy the requirement to machining accuracy.
