Abstract
The present invention discloses a kind of connection structure that automatic processing precise deep hole is realized in center lathe, middle carriage, tailstock, active block and motion block；Active block is in polygonized structure, and side is equipped with connected unit a；Motion block is in 5/6ths discs, and one side is stepped, equipped with connected unit b；The bolt hole of 4 ￠ 8 is equipped with active block and motion block；Active block is fixed on the upper part of middle carriage by interior six square bolt；Motion block is fixed on the lower part of tailstock by interior six square bolt；Active block and motion block are arranged between middle carriage and tailstock；Realize that tailstock is fed with middle carriage linkage by being sternly engaged with the connected unit b in motion block by the connected unit a in active block.The present invention realizes that the movement of middle carriage drives the synchronous interaction of tailstock, tailstock feeding has been reached by just automatically transformation manually and has both been met detail drawing technological requirement, reduce labor intensity, effectively reduced the purpose of processing cost.
Description
Technical field
It is more particularly to a kind of to realize automatic add in center lathe the present invention relates to aero-engine processing and manufacturing technology
The connection structure of work precision deep bore.
Background technology
Under normal conditions, machine parts'precise deep hole machining is carried out using deep hole drilling equipment.Due to depth drill cost of equipment
Height, single component process equipment utilization rate is low, increases the manufacture cost of part.And with engine lathe processing deep hole labor intensity
Greatly, the handle of tailstock is driven to feed when being cut uneven by hand, rough surface plating does not reach drawing requirement, part qualification rate
Low, cutter is costly.
The content of the invention
In order to solve the above technical problems, realize that automatic processing precise is deep in center lathe the object of the present invention is to provide one kind
The connection structure in hole, concrete technical scheme are as follows：
A kind of connection structure that automatic processing precise deep hole is realized in center lathe, middle carriage, tailstock, active block and passive
Block；
The active block is in polygonized structure, and side is equipped with connected unit a；
The motion block is in 5/6ths discs, and one side is stepped, equipped with connected unit b；
The bolt hole of 4 ￠ 8 is equipped with the active block and motion block；
The active block is fixed on the upper part of middle carriage by interior six square bolt；
The motion block is fixed on the lower part of tailstock by interior six square bolt；
The active block and motion block are arranged between middle carriage and tailstock；
Realize that tailstock links with middle carriage by being sternly engaged with the connected unit b in motion block by the connected unit a in active block
Feeding.
A kind of connection structure that automatic processing precise deep hole is realized in center lathe, its preferred solution are the master
Motion block and motion block are made of medium carbon steel.
A kind of application method for the connection structure that automatic processing precise deep hole is realized in center lathe, includes the following steps,
Step 1：Boring, expand, before fraising, by front and rear and move up and down middle carriage, making active block, motion block by sternly stinging
Close, so that middle carriage and tailstock linkage work；
Step 2：Feed form is set, is adjusted to self-acting feed, under active block and motion block effect, makes active block, quilt
Motion block separates, and recovers the original working status of lathe.
Beneficial effects of the present invention：Technical scheme realizes that middle carriage drives the synchronous interaction of tailstock, makes tailstock
The modern transformation by manual extremely excitement, it is easy to operate effectively effectively to reduce vibrations, improve brill, expansion, the precision of fraising.Change skill
Art scheme may be implemented in machine tool processing below ￠ 20mm, length diameter ratio up to 25 precision deep bore, Nei Jing surfaces after processing
Roughness reaches 0.8mm, and cylindricity is no more than 0.01mm.Extensive reference work can in industry be provided by changing the solution of technical barrier
With.This structure work in-process is easy to operate, its automatic processing can reduce the labor intensity of operating personnel, save 50% cutter expense
And process time.

The active block 3 and motion block 4 are arranged between middle carriage 1 and tailstock 2；
Realize that tailstock 2 is dragged with by being sternly engaged with the connected unit b6 in motion block 4 by the connected unit a5 in active block 3
The linkage feeding of plate 1.
The active block 3 and motion block 4 are made of medium carbon steel.
A kind of application method for the connection structure that automatic processing precise deep hole is realized in center lathe, includes the following steps,
Step 1：Boring, expand, before fraising, by front and rear and move up and down middle carriage 1, making active block 3, motion block 4 by tight
Occlusion, so that middle carriage 1 and 2 linkage work of tailstock；
Step 2：Feed form is set, is adjusted to self-acting feed, in the case where active block 3 and motion block 4 act on, makes active block
3rd, motion block 4 separates, and recovers the original working status of lathe.
