The awl of 2, four compressible reference column heads hole covers four protruding spheres of the big end end face of main shaft, needs artificial feel rotating table and want four to forward the position simultaneously to carefully, must handle electric lifting tool crawl lifting turntable mechanism repeatedly, and locating speed is slow.
[summary of the invention]
The utility model proposes a kind of rotary tablet machine and can transfer the platform location structure at the problems referred to above, makes can transfer platform and debug convenient in assembling process and reliable, and daily transposing turntable can accurately be located fast.
The technical solution of the utility model is: a kind of rotary tablet machine can be transferred the platform location structure, comprise turntable bottom face and main shaft large end face, it is characterized in that: the turntable bottom face is provided with the reference column hole that is positioned at same circumference and is evenly distributed, the reference column hole is built-in with the reference column assembly, and the head of reference column assembly is protruding sphere; The main shaft large end face is provided with the awl corresponding with reference column assembly on turntable bottom face hole, and awl hole drift angle is α, and the hole be D1 deeply, and place, awl hole circumference is a ring awl groove, and boring the groove drift angle is β, and groove depth is D2,90 °＜α＜β wherein, D2＜D1.
The reference column assembly is made up of pressure-regulating sleeve, spring base, spring, guide rod, spacer shell, steel ball and steel ball lid, pressure regulation is with screw thread and spacer shell is connected to form shell, spacer shell is connected with the turntable bottom face, shell inner spring seat pressing spring, spring housing is on guide rod, spacer shell is stretched out in the guide rod termination, and the steel ball lid contains steel ball and is connected to together on the guide rod termination.
The utility model changes original positioning screw hole into unthreaded hole and holds the reference column assembly, pressure-regulating sleeve and spacer shell are connected to form shell and contain all components and form independently compressible reference column assembly, before general assembly, can reach predefined numerical value, and can guarantee the uniformity of all initial support power at the starting force that turntable external application special tooling is adjusted supporting one by one.Secondly, the sphere that plays the role of positioning is moved to the head of reference column assembly on the turntable bottom face from original main shaft large end face, be located at the hole of the awl on the original reference column on the main shaft large end face simultaneously and have ring awl groove to be communicated with.
Install when connecting, above the big end end face of main shaft, drop to compressible reference column head sphere gradually and contact transferring platform to main shaft large end face ring awl groove, the hand rotation turntable makes the sphere head all enter the awl hole along ring awl groove then, can finish accurate location soon.
