Accumulated error；Simultaneously on one cylindrical screen blank busbar of milling during axial mesh, positioning tooth wheel rotates a tooth, and positioning can
It leans on, reduces and avoid artificially to obscure angle calculation mistake and angle, reduce operation difficulty, realize and simplify production.
In addition, the configuration of the present invention is simple, mandrel upper screen cloth blank mounting portion both ends are equipped with locking nut, can coordinate for each
Kind length sieve blank milling, also disclosure satisfy that the requirement of batch micro operations.
Description of the drawings
Fig. 1 is the front view of the present invention.
Fig. 2 is the side view of the present invention.
Specific embodiment
Invention is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, the present invention includes two engine bases（Engine base 2 and engine base 4）, mandrel 11, dividing gear 1, positioning compression bar 5
And spring 8；Engine base 2 and engine base 4 are arranged in parallel, and engine base is equipped with mandrel mounting groove（It can also be mandrel mounting hole）, mandrel 11
It is supported in the mandrel mounting groove of two engine bases.Engine base 2 is equipped with the threaded hole for connecting mandrel mounting groove, engine base 2 and machine with engine base 4
Stop screw rod 6 is respectively equipped in the threaded hole of seat 4, stop screw rod 7, stop screw rod 6, stop screw rod 7 can hold out against mandrel 11, anti-
Only it is rotated when processing sieve.Dividing gear 1 is equipped on the mandrel at engine base 2, positioning compression bar 5 is located at indexing tooth
1 top of wheel, one end and the engine base 2 for positioning compression bar 5 are hinged, and positioning compression bar 5 is towards on the side of dividing gear（On bottom surface）It is equipped with
Latch, latch can be embedded in a tooth socket of dividing gear 1；It positions and spring 8 is equipped between compression bar 5 and engine base 2, spring 8 makes
Compression bar 5 must be positioned and push down dividing gear 1.Apply certain spring tension when positioning compression bar 5 and dividing gear 1 and coordinating, it both can be with
Precise positioning can avoid jumping tooth again.Locking nut there are two being set between two engine bases 2 on the mandrel 11（Locking nut 9 or lock
