Knob 15 is set on thread bush 13, knob 15 is interference fitted with thread bush 13, meanwhile, knob 15 and thread bush 13
Between pass through the positioning of two positioning screws being arranged symmetrically 14 and fix.
Left support 9 and right support 11 are further sleeved on fine tuning screw rod 8, wherein, left support 9 is sleeved on 801 one end of threaded hole；
Right support 11 is sleeved on 802 one end of smooth inner bore；By left support 9 and right support 11 to fine tuning screw rod 8 in the process of horizontally slipping
In positioned.
As shown in Figure 7 to 9, the upper surface of voussoir 6 and the lower face of elastic construction are inclined-plane, and oblique on voussoir 6
Face and the inclined-plane on elastic construction are parallel to each other.
The bond type through-hole 601 that two are further opened on voussoir 6 to be centrosymmetrically arranged.
At work：
Knob 15 rotates a lattice counterclockwise, drives fine tuning screw rod 8, voussoir screw 7 and voussoir 6 all whole therewith to core bar 16
It moves to right, which can realize that by convert rotational motion be linear motion.
Crimp can occur for the face that the ramp of voussoir 6 is contacted with the elastic construction of tool apron main body 3, finely tune the effect reached
Fruit is exactly one lattice of rotation counterclockwise of knob 15, and the elastic construction of tool apron is because crimp is in 1 μm of vertical direction raising, knob on the contrary
15 rotate clockwise a lattice, and the elastic construction of tool apron is because crimp is in 1 μm of vertical direction reduction.
Meanwhile the fine setting scope of entire fine tuning structure, by the way that journey limiting device is adjusted to limit, as shown in Figure 10, the limiting fills
It puts including preloading spring 17 and stop screw 18, wherein, there are two the settings of preloading spring 17, and with the central symmetry cloth of voussoir 6
It puts, one end of preloading spring 17 is connect with one end end face of the close left support 9 of voussoir 6, the other end of preloading spring 17 and bottom
Seat main body 3 connects；Meanwhile the one end of voussoir 6 far from left support 9 is provided with shell 10, it is right by shell 10 and preloading spring 17
The left end limit of voussoir 6 is limited.
There are two the settings of stop screw 18, is separately mounted to by 601, meanwhile, spring is set on stop screw 18,
The extreme right of voussoir 6 is defined by stop screw 18, prevents voussoir 6 and left support 9 from colliding, leads to tool apron master
The tune journey of body is not accurate.
Voussoir 6 is one of important part of this secondary design, and two sides of preload of Linear fine tuning and tool apron are completed for tool apron
Face plays indispensable effect.3 structure of tool apron main body seems in disorder complexity, is actually an entirety, wherein most important knot
Structure is then the elastic construction of main body upper left quarter.Power is transmitted to voussoir 6 by fine tuning screw rod 8, and power is transmitted to tool apron master by voussoir 6 by inclined-plane
The elastic construction of body 3, brings it about linear deformation, completes the fine tuning of point of a knife.8 semicolumn through-holes in tool apron main body 3 are to use
What the special process method of Wire EDM obtained, therefore ensure that the integraty of the part.
