Description
Technical field
The present invention relates to mechanical device design field, more particularly to a kind of drilling and milling machine screw mandrel shaft block.
Background technology
A variety of driving parts are generally used on lathe, screw mandrel is for carrying out feeding fortune in these driving parts
The very common part of the dynamic class transmitted, screw mandrel needs the pedestal for support screw, traditional silk when being installed on lathe
Pole socket body is more to be processed with lathe sheet, and because the place of some transition does not carry out rounding or chamfering, these positions are easily produced
Raw stress concentration, and inside may have internal stress, cause bearing capacity poor, the part on lathe when mounted some
Part can protrude, and security is poor, due to being bothered without the special oil injection structure of design, therefore oil filling, therefore design
A kind of simple structure, the stress concentration of bearing seat is small, and internal stress is small, and bearing capacity is strong, and long service life, security is good, note
Oily convenient drilling and milling machine screw mandrel shaft block seems very necessary.
The content of the invention
The purpose of the present invention is exactly that security is poor, and lubricating oil adds in order to overcome traditional screw mandrel pedestal to cause bearing capacity poor
Troublesome defect is noted, a kind of drilling and milling machine screw mandrel shaft block is devised, simple structure, the stress concentration of bearing seat is small, internal stress
Small, bearing capacity is strong, and long service life, security is good, and oiling is convenient.
The required technical problem for solving of the invention can be achieved through the following technical solutions：
A kind of drilling and milling machine screw mandrel shaft block, including bearing seat, boss, the bearing seat are longitudinal cross-section close to ladder
For semicylinder combines together with the cylindrical boss in the middle of the steel plate of shape, its bottom, also including cylindrical hole, bearing hole, note
Oilhole, the bottom of the bearing seat or so two ends do in the arc-shaped, and the cylindrical hole, the axle are machined with circular arc shaped position
Bearing body is fixed through the cylindrical hole using bolt with bed piece, and the bearing hole is machined with the center of the boss.
The transition position of the bearing seat uses arc transition, radius of corner to take 2~3mm.
The bearing seat is cast member, and it is internal in the absence of sand holes, shrinkage porosite, crack defect.
The end of the cylindrical hole is machined with counterbore.
The crown center position of the boss is provided with the oil filler point.
As a result of above technical scheme, the invention has the advantages that：
Designed drilling and milling machine screw mandrel shaft block is combined using bearing seat, boss, cylindrical hole, bearing hole, oil filler point,
The transition position of bearing seat uses arc transition, radius of corner to take 2~3mm, and the stress concentration of bearing seat is small, bearing capacity
By force, bearing seat is cast member, and the internal stress of bearing seat is small, is hardly damaged, long service life, and the end of cylindrical hole is machined with
Counterbore, when bearing seat being fixed on into bed piece using bolt, bolt head will not protrude from the surface of bearing seat, safety
Property it is good, the crown center position of boss is provided with oil filler point, when screw mandrel works, can be lubricated toward internal injection using lubricating cup by the way of
Oil, simple structure, oiling is convenient.

Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
A kind of drilling and milling machine screw mandrel shaft block, including bearing seat 1, cylindrical hole 2, boss 3, bearing hole 4, oil filler point 5, bearing
Pedestal 1 be longitudinal cross-section close to trapezoidal steel plate, for semicylinder combines together with cylindrical boss 3 in the middle of its bottom, axle
The bottom of bearing body 1 or so two ends do in the arc-shaped, and cylindrical hole 2 is machined with the position, and bearing seat 1 can be worn using bolt
Cross cylindrical hole 2 to be fixed with bed piece, bearing hole 4 is machined with the center of boss 3, screw mandrel is in bearing hole by bearings
In 4, simple structure, low cost.
The transition position of bearing seat 1 uses arc transition, radius of corner to take 2~3mm, the stress concentration of bearing seat 1
Small, bearing capacity is strong.
Bearing seat 1 is cast member, and it is internal in the absence of defects, the internal stress of bearing seat 1 such as sand holes, shrinkage porosite, crackles
It is small, it is hardly damaged, long service life.
The end of cylindrical hole 2 is machined with counterbore, when bearing seat 1 being fixed on into bed piece using bolt, bolt head
The surface of bearing seat 1 will not be protruded from, security is good.
The crown center position of boss 3 is provided with oil filler point 5, when screw mandrel works, can be noted toward internal by the way of lubricating cup
Enter lubricating oil, simple structure, oiling is convenient.
Drilling and milling machine screw mandrel shaft block disclosed in this invention, the transition position of bearing seat 1 uses arc transition, fillet
Radius takes 2~3mm, and the stress concentration of bearing seat 1 is small, and bearing capacity is strong, and bearing seat 1 is cast member, bearing seat 1 it is interior
Stress is small, is hardly damaged, long service life, and the end of cylindrical hole 2 is machined with counterbore, is fixed on bearing seat 1 using bolt
During bed piece, bolt head will not protrude from the surface of bearing seat 1, and security is good, and the crown center position of boss 3 is provided with
