Description
Technical field
This utility model relates to lathe process field, particularly a kind of lathe safety support support set.
Background technology
In machining, turning is the most frequently used processing method.Traditional longaxones parts turning, generally uses a folder
One top, centre add centre frame mode and carry out clamping realization, as shown in Figure 6, but when processing major axis in the case of following four kinds
But centre frame cannot be directly used:
1, the least when the elongated diameter of axle processed, beyond the range of accommodation of center rest support pulley L, roller length L is i.e.
Make to be adjusted to greatest length and be all not readily accessible to axle cylindrical, as shown in Figure 7；
2, the axle processed is black skin, and surface relief is uneven, and only local can be with center rest support roller for axle cylindrical
Contact；As shown in Figure 8.
3, when special-shaped axial workpieces such as machining crankshafts, it needs the cylindrical centre of gyration of support zone to turn round with lathe spindle
Center is not coaxial, when axle rotates, two rollers all can be had cannot to support to axle surface；As shown in Figure 9.
4, spend greatly when major axis, when axle rotates, centre frame has one or two rollers and cannot support to axle
Surface.As shown in Figure 9.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of lathe safety support support set, it is possible to solve existing skill
In art encounter above-mentioned several in the case of, it is difficult to the problem using centre frame, and be able to ensure that the safety during use.
For solving above-mentioned technical problem, this utility model be the technical scheme is that a kind of lathe safety support support set,
Bushing core is provided with the hole passed for workpiece, is respectively arranged at the two ends with at least three for fixing the bolt of workpiece at sleeve；
It is provided with outer layer sleeve in the position of bolt, when the external diameter of outer layer sleeve is positioned at top more than bolt
Circumscribed circle diameter.
Preferably in scheme, the position corresponding with bolt at outer layer sleeve is provided with through hole.
Preferably in scheme, outer layer sleeve is connected with the outer wall of sleeve by multiple connection posts.
A kind of lathe safety support support set that this utility model provides, it is possible to solve slender axles, blank axle, special-shaped axle and curved
Bent axles etc. in particular cases cannot use centre frame to be supported, thus cannot the problem of direct turning.The outer layer sleeve arranged,
Ensure that the head of bolt will not reach the outer surface of outer layer sleeve, it is ensured that operation safety.This utility model can
Size according to shaft diameter designs different specifications in certain range of work, to adapt to turning different-diameter axial workpiece.

Detailed description of the invention
Such as Fig. 1, in 2, a kind of lathe safety support support set, sleeve 1 center is provided with the hole passed for workpiece 6, at sleeve 1
It is respectively arranged at the two ends with at least three for fixing the bolt 2 of workpiece 6；Preferably, it is respectively arranged at the two ends with four location at sleeve 1
Bolt 2.
Be provided with outer layer sleeve 7 in the position of bolt 2, the external diameter of outer layer sleeve 7 is positioned at top more than bolt 2
Time circumscribed circle diameter.
Preferably in scheme, it is provided with through hole 9 in the position that outer layer sleeve 7 is corresponding with bolt 2.
Preferably in scheme, outer layer sleeve 7 is connected with the outer wall of sleeve 1 by multiple connection posts 8.
During use, this utility model being enclosed within workpiece 6, the correct position of axle the most to be processed, with inner hexagon spanner from outward
Through hole 9 on layer sleeve 7 puts in and regulates soket head cap screw corresponding on it:
1, when the axle that the turning diameter of axle is the least, this utility model serves the effect increasing the diameter of axle, shown in Fig. 4；
2, it is black skin, rough and uneven in surface when processed axle outer round surface, adjusts each bolt 2 and support at crown of roll, concave surface
Place, part can be screwed into deeper, and as shown in Figure 5, remaining bolt 2 is supported on the high point position that axle cylindrical is relative, twists
Enter the degree of depth suitable more shallow, by means of positive axle center, to regulate bolt support length by adjusting the stroke of bolt 2, until sleeve 1
Cylindrical and lathe spindle are coaxial, then to sleeve 1 cylindrical medium position, centre frame frame can be completed turnery.
3, when processed bending shaft or coaxial time adjust with said method 2.
This utility model one is to improve production efficiency, and the process route of tradition working shaft-like part is: centering cylindrical；Add
Gong Pai building shelves；Centre frame is bearing in turning Zhou Wai garden or end face on row building shelves.
And use structures and methods working shaft-like part of the present utility model, decrease processing row's building shelves operation, only need by
Safety support support set is inserted in axial workpiece, adjusts bolt, the outer garden of axial workpiece or facing can be passed through sleeve after centering
1 realizes ingenious transition between axle with centre frame is connected.
Two are reduction of processing cost, easy installation and removal of the present utility model, wide accommodation, can be certain straight in processing
In the axial workpiece of footpath scope, clamping uses repeatedly, shortens the process-cycle.
Three is safe and reliable, owing to adding safty shield, has been completely covered by protruding from 8 location on sleeve 1 surface
Bolt 2, when preventing work, bolt with part high-speed rotary then hangs up the medicated clothing of the operator the most aside worked, and causes safety
The generation of accident so that it is safer that operation becomes, and helps to ensure that safety in production.
The above embodiments are only optimal technical scheme of the present utility model, and are not construed as limit of the present utility model
System, on the premise of not conflicting mutually, every technical characteristic that this utility model is recorded can be combined with each other.Guarantor of the present utility model
The technical scheme that the scope of protecting should be recorded with claim, replaces including the equivalent of technical characteristic in the technical scheme that claim is recorded
The scheme of changing is protection domain.Equivalent the most in this range is improved, also within protection domain of the present utility model.
